Referring to fig. 1, an embodiment of the present invention provides a tuck presser 10 for a circular knitting machine. The tucking presser 10 comprises a tucking presser 11, a tucking lead-in part 12 and a tucking presser mounting part 13, the tucking presser 11 and the tucking lead-in part 12 are positioned at the same end of the tucking presser mounting part 13; a tuck presser 11 is formed with a tuck presser plane 1101 on a surface thereof remote from the tuck presser mounting portion 13, a tuck introduction curved surface 1201 is formed on a surface thereof remote from the tuck presser mounting portion 13 of the tuck introduction portion 12, the tuck introduction curved surface 1201 is curved toward the tuck presser mounting portion 13, and the tuck presser plane 1101 is smoothly connected to the tuck introduction curved surface 1201.

In the tuck presser 10 of the present embodiment, the movement locus of the yarn can be limited during tucking mainly by the cooperation of the tuck introduction part 12 and the tuck presser 11, and the risk of the occurrence of loop floating can be reduced. Specifically, through the cooperation of the tuck introduction curved surface 1201 and the tuck pressing plane 1101, the yarns smoothly transit to the pressing plane 1101 along the introduction curved surface 1201, and a stable position state is maintained under the action of the pressing plane, so that the position of the yarns is favorably controlled, the risk of coil floating is reduced, and the quality of the fabric is improved.

Further, in the tuck presser 10 in this embodiment, the tuck presser 11, the tuck introduction portion 12, and the tuck presser mounting portion 13 are supported in cooperation with each other in use, and are not easily deformed in the processing process, and a stable structure can be maintained, which is advantageous for improving stability of tuck.

It is understood that "plane" and "curved" in the present invention mean two forms of surfaces. "planar" is understood to mean that the slope is equal throughout the surface, and "curved" is understood to mean a surface with some curvature.

In a specific example, the tuck presser 10 is constituted by a tuck presser 11, a tuck introduction part 12, and a tuck presser mounting part 13, the tuck presser 11 and the tuck introduction part 12 being located at the same end of the tuck presser mounting part 13; a tuck presser 11 is formed with a tuck presser plane 1101 on a surface thereof remote from the tuck presser mounting portion 13, a tuck introduction curved surface 1201 is formed on a surface thereof remote from the tuck presser mounting portion 13 of the tuck introduction portion 12, the tuck introduction curved surface 1201 is curved toward the tuck presser mounting portion 13, and the tuck presser plane 1101 is smoothly connected to the tuck introduction curved surface 1201.

In one particular example, tuck-in plane 1101 is tangent to tuck-in curve 1201. At this time, the tucking presser plane 1101 and the tucking introduction curved surface 1201 can make smooth transition, so that the yarn smoothly moves along the tucking presser plane 1101 and the tucking introduction curved surface 1201, and the tucking quality is further improved.

Referring again to fig. 1, the tuck presser 11 extends toward one side of the tuck presser mounting portion 13, and the tuck lead-in portion 12 extends toward the other side of the tuck presser mounting portion 13. At this time, a relief area is formed between the projecting end of the tuck presser 11 and the tuck presser mounting portion 13, and a relief area is formed between the projecting end of the tuck introduction portion 12 and the tuck presser mounting portion 13. Therefore, the installation uniformity can be improved, and the interference of other parts in the circular knitting machine on the tucking presser 10 can be avoided.

Further, the distance between one end of the tuck presser 11 away from the tuck presser mounting portion 13 and the tuck presser mounting portion 13 is 5cm to 10 cm. That is, the distance represented by a in FIG. 1 is in the range of 5cm to 10 cm. Within this distance range, the tuck presser 10 better adapts to the length of the tuck yarn, keeping the tuck stable. Alternatively, the distance between the tuck presser mounting part 13 and one end of the tuck presser 11 remote from the tuck presser mounting part 13 is 5cm, 6cm, 7cm, 8cm, 9cm, or 10 cm.

Further, an end surface 1102 of the tuck presser 11 at an end remote from the tuck presser mounting portion 13 is perpendicular to the tuck presser plane 1101.

In a specific example, the tuck guide-in portion 12 is spaced from the tuck presser mounting portion 13 by a distance of 2cm to 5cm from one end thereof remote from the tuck presser mounting portion 13. That is, the distance represented by b in FIG. 1 ranges from 2cm to 5 cm. Within this distance range, the tuck introduction portion 12 stably introduces the yarn, and the stability of tucking is further improved. Alternatively, the distance between the tuck guiding section 12 and the tuck presser mounting section 13 at the end away from the tuck presser mounting section 13 is 2cm, 2.5cm, 3cm, 3.5cm, 4cm, 4.5cm, or 5 cm.

Alternatively, the projecting end of the tuck presser 11 is smoothly connected to the tuck presser mounting portion 13, and the projecting end of the tuck lead-in portion 12 is smoothly connected to the tuck presser mounting portion 13. Therefore, the acting force of the yarn on the tuck pressing part 11 can be effectively dispersed, and the tuck pressing piece 10 can keep better structural stability.

Further, a surface of the tuck presser 11 close to the tuck presser mounting portion 13 is flush with a surface of the tuck introduction portion 12 close to the tuck presser mounting portion 13.

In a specific example, the tuck presser mounting part 13 is provided with a through hole 1301, and the through hole 1301 is used for mounting the tuck presser 10 of the circular knitting machine. For example, the tuck presser 10 is attached to the circular knitting machine through the through hole 1301.

Further, the through hole 1301 has a space for avoiding for adjusting the installation position of the tucking presser 10 of the circular knitting machine. The through hole 1301 is provided with a yielding space, so that the installation position of the tucking yarn pressing piece 10 can be conveniently controlled.

In a specific example, the tuck presser 11, the tuck introduction portion 12, and the tuck presser attachment portion 13 are integrally formed. The processing and forming are facilitated, and the stable structure of the tucking presser 10 is kept. Alternatively, the tuck presser 11 is a hard tuck presser 11, and the tuck introduction portion 12 is a hard tuck introduction portion 12.

In a specific example, the tuck-in presser 11 has a thickness of 0.5cm to 1cm, and the tuck-in guide 12 has a thickness of 0.5cm to 1 cm. For example, the tuck hold 11 may have a thickness of, but not limited to, 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, or 1 cm. The thickness of the tuck-in portion 12 may be, but is not limited to, 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, or 1 cm. Further, the tuck presser 11 has a thickness equal to that of the tuck introduction portion 12. Further, the thickness of the tuck presser 11, the thickness of the tuck introduction part 12, and the thickness of the tuck presser mounting part 13 are all equal. At this time, the tuck presser 10 maintains an overall uniform thickness.

In one specific example, tuck-in yarn plane 1101 is a smooth plane and tuck-in curve 1201 is a smooth curve.

In yet another embodiment of the present invention, a yarn presser is provided, which includes a tuck presser 10.

A further embodiment of the present invention provides a circular knitting machine including a tuck presser 10.

Referring to fig. 2, an embodiment of the present invention provides a looping yarn pressing sheet 20 of a circular knitting machine. The looping yarn pressing sheet 20 comprises a looping yarn pressing part 21 and a looping yarn pressing sheet mounting part 22, wherein the looping yarn pressing part 21 is positioned at one end of the looping yarn pressing sheet mounting part 22; one surface of the looping yarn pressing part 21, which is far away from the looping yarn pressing piece mounting part 22, is provided with a first sub yarn pressing plane 2101, a transition curved surface 2102 and a second sub yarn pressing plane 2103 which are connected in sequence, the first sub yarn pressing plane 2101 is parallel to the second sub yarn pressing plane 2103, the first sub yarn pressing plane 2101 protrudes out of the second sub yarn pressing plane 2103, and the first sub yarn pressing plane 2101 and the second sub yarn pressing plane 2103 are respectively and smoothly connected with the transition curved surface 2102.

In the looped yarn pressing sheet 20 of the present embodiment, the movement locus of the yarn is mainly defined by the cooperation of the first sub yarn pressing plane 2101, the transition curved surface 2102 and the second sub yarn pressing plane 2103. In the looping process, the track and the looping path of the yarn can be well buffered, the track of the yarn is adjusted to a certain degree through the transition curved surface 2102, the tension of the yarn is properly released, the looping stability can be improved, meanwhile, the problem that the fabric is broken in the looping process is effectively avoided, and the yield of the fabric and the quality of the fabric are improved.

In a specific example, the height of the first sub-pressing plane 2101 protruding from the second sub-pressing plane 2103 is 1mm to 9 mm. That is, the distance indicated by c in FIG. 2 ranges from 1mm to 9 mm. Optionally, the height of the first sub-pressing plane 2101 protruding from the second sub-pressing plane 2103 is 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm or 9 mm. When the height of the first sub-pressing plane 2101 protruding from the second sub-pressing plane 2103 is too small, a good transition effect is difficult to achieve, and when the height is too large, yarn displacement may be too large, which may adversely affect looping.

In a specific example, the first sub-pressing plane 2101 is tangent to the curved transition surface 2102, and the second sub-pressing plane 2103 is tangent to the curved transition surface 2102. At this time, the yarn can be more smoothly transited between the first sub-pressing plane 2101 and the transition curved surface 2102 and between the transition curved surface 2102 and the second sub-pressing plane 2103, and the looping quality of the yarn is effectively ensured.

Further, the distance between one end of the looping yarn pressing part 21 far away from the looping yarn pressing piece mounting part 22 and the looping yarn pressing piece mounting part 22 is 5 cm-10 cm. That is, the distance represented by d in FIG. 2 ranges from 5cm to 10 cm. Within this distance, the loop-forming presser 20 is better adapted to the length of the looped yarn, maintaining a stable loop formation. Alternatively, the distance between the end of the looping presser 21 away from the looping presser mounting part 22 and the looping presser mounting part 22 is 5cm, 6cm, 7cm, 8cm, 9cm or 10 cm.

Further, an end surface 2104 of the looping presser 21 at an end remote from the looping presser mounting part 22 is perpendicular to the first sub-presser plane 2101.

In a specific example, the looping presser 20 further includes a looping lead-in portion 23, the looping lead-in portion 23 and the looping presser 21 are located at the same end of the looping presser mounting portion 22; a looping introduction curved surface 2301 is formed on one surface of the looping introduction part 23 far away from the looping yarn pressing piece mounting part 22, and the looping introduction curved surface 2301 is bent towards the looping yarn pressing piece mounting part 22; the loop-forming curved introduction surface 2301 is smoothly connected to the first sub-pressing plane 2101. The yarn is more stably fed into the yarn pressing position of the loop yarn pressing piece 20 by the loop guide-in portion 23, and the loop stability is improved. Optionally, the loop-forming lead-in curved surface 2301 is tangent to the first sub-packing plane 2101.

In a specific example, the looping presser 21 projects toward one side of the looping presser mounting part 22, and the looping introduction part 23 projects toward the other side of the looping presser mounting part 22. At this time, a relief area is formed between the protruding end of the looping yarn pressing part 21 and the looping yarn pressing piece mounting part 22, and a relief area is also formed between the protruding end of the looping lead-in part 23 and the looping yarn pressing piece mounting part 22, so that the looping yarn pressing piece 20 can be conveniently mounted and matched with other components.

Further, the distance between the end of the looping guide-in part 23 away from the looping presser mounting part 22 and the looping presser mounting part 22 is 2cm to 5 cm. That is, the distance indicated by e in FIG. 2 ranges from 2cm to 5 cm. Within this distance range, the stitch guide 23 stably guides the yarn, and the stability of the stitch is further improved. Alternatively, the distance between the end of the looping introduction portion 23 away from the looping presser mounting portion 22 and the looping presser mounting portion 22 is 2cm, 2.5cm, 3cm, 3.5cm, 4cm, 4.5cm, or 5 cm.

In a specific example, the protruding end of the looping press part 21 is smoothly connected to the looping press piece mounting part 22, and the protruding end of the looping introduction part 23 is smoothly connected to the looping press piece mounting part 22. This effectively disperses the force of the yarn on the looped yarn-pressing portion 21, and the looped yarn-pressing portion 21 maintains a better stability.

Further, a surface of the looping yarn pressing portion 21 adjacent to the looping yarn pressing piece mounting portion 22 is flush with a surface of the looping introduction portion 23 adjacent to the looping yarn pressing piece mounting portion 22.

In a specific example, the looping presser mounting part 22 is provided with a through hole 2201, and the through hole 2201 is used for mounting the looping presser 20 of the circular knitting machine. For example, the looping presser 20 is attached to the circular knitting machine through the through hole 2201.

Further, the through hole 2201 has a space for avoiding for adjusting the installation position of the looping presser 20 of the circular knitting machine. The through hole 2201 is provided with a yielding space, so that the installation position of the looping yarn pressing piece 20 can be conveniently controlled.

In a specific example, the looping yarn pressing portion 21, the looping introduction portion 23, and the looping yarn pressing piece attaching portion 22 are integrally formed. The processing and forming are facilitated, and the stable structure of the looped yarn pressing sheet 20 is kept. Alternatively, the looping yarn portion 21 is a hard looping yarn portion 21, and the looping introduction portion 23 is a hard looping introduction portion 23.

In a specific example, the thickness of the loop forming and yarn pressing portion 21 is 0.5cm to 1cm, and the thickness of the loop forming and yarn introducing portion 23 is 0.5cm to 1 cm. For example, the thickness of the looped pile yarn portion 21 may be, but is not limited to, 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, or 1 cm. The thickness of the looping introduction portion 23 may be, but is not limited to, 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, or 1 cm. Further, the thickness of the loop pressing portion 21 is equal to the thickness of the loop introducing portion 23. Further, the thickness of the looping presser 21, the thickness of the looping introduction portion 23, and the thickness of the looping presser mounting portion 22 are all equal. At this time, the entire thickness of the loop presser 20 is kept uniform.

In a specific example, the first sub-pressing plane 2101 is a smooth plane, the second sub-pressing plane 2103 is a smooth plane, the transition curved surface 2102 is a smooth curved surface, and the loop-forming introduction curved surface 2301 is a smooth curved surface.

A further embodiment of the invention provides a circular knitting machine comprising a presser device 30.

Referring to fig. 4 and 5, an embodiment of the present invention provides a needle-containing corner block 40 of a circular knitting machine. The needle-containing corner block 40 includes a needle-containing base 41, a first needle-containing stopper 42, and a second needle-containing stopper 43; the first needle-containing stopper 42 and the second needle-containing stopper 43 both protrude from the needle-containing base 41, and a gap is provided between the first needle-containing stopper 42 and the second needle-containing stopper 43 for forming a needle rail 44 through which a knitting needle passes.

The first needle-containing retainer 42 has a first needle-containing introduction portion 4201 and a second needle-containing discharge portion 4302, and the second needle-containing retainer 43 has a second needle-containing introduction portion 4301 and a second needle-containing discharge portion 4302; the first needle-containing lead-in portion 4201 and the second needle-containing lead-in portion 4301 are fitted to form a needle-containing lead-in track, the first needle-containing lead-out portion 4202 and the second needle-containing lead-out portion 4302 are fitted to form a needle-containing lead-out track, the first needle-containing lead-out portion 4202 has a first needle-containing lead-out plane 42021, the first needle-containing lead-out plane 42021 faces the second needle-containing lead-out portion 4302, the second needle-containing lead-out portion 4302 has a second needle-containing lead-out plane 43021, the second needle-containing lead-out plane 43021 faces the first needle-containing lead-out portion 4202, and the first needle-containing lead-out plane 42021 and the second needle-containing lead-out plane 43021 are parallel.

The knitted air layer fabric is widely favored by consumers by the properties of comfortable hand feeling, fluffiness, softness, sweat releasing, warm keeping, moisture absorption, air permeability and the like, and is widely applied to the preparation of sports clothes, casual clothes and professional clothes. Currently, sandwich type knitted air layer fabrics are used more, as shown in fig. 16. In the "sandwich" knitted air layer fabric shown in fig. 16, the surface layer and the inner layer are connected by the yarn count of the middle layer through the tuck structure to form the "sandwich" type knitted air layer fabric.

Although the sandwich type knitted air layer fabric has good texture, the inner layer and the surface layer are easy to drill out due to the yarn count of the middle layer in the using process, and the problems of yarn leakage, pilling and the like occur, so that the surface of the fabric is uneven. Based on the defects of the sandwich type knitted air layer fabric, the sandwich type knitted air layer fabric appears. The surface layer, the subsurface layer, the hollow layer, the sub-inner layer and the inner layer are sequentially formed from the surface to the inner layer of the 'wuwen' type knitted air layer fabric shown in fig. 17, and the design can improve the surface performance of the 'wuwen' type knitted air layer fabric to a certain extent. However, the traditional knitting equipment has difficulty in continuously forming the surface layer and the inner layer of the five-cultural-relic type knitted air layer fabric on the basis of keeping the needle-containing structure of the three-cultural-relic.

In the pin-containing corner block 40 of the present embodiment, by the cooperation of the first pin-containing retainer 42 and the second pin-containing retainer 43, the first pin-containing guide portion 4201 and the second pin-containing guide portion 4301 cooperate to form a pin-containing guide track, the first pin-containing guide portion 4202 and the second pin-containing guide portion 4302 cooperate to form a pin-containing guide track, the first pin-containing guide portion 4202 has a first pin-containing guide plane 42021, the second pin-containing guide portion 4302 has a second pin-containing guide plane 43021, and the first pin-containing guide plane 42021 and the second guide plane are parallel. At this time, when the needle-containing corner block 40 is used, the yarn can be guided on the guiding track without stitch return or stitch formation, so that the surface layer and the inner layer of the five-culture type knitting air layer fabric can be formed on the basis of the three-culture type needle-containing structure smoothly, and the quality of the fabric is improved.

This allows the knitting needles to be guided more smoothly into the needle-containing corner block 40.

Further, the first needle-containing guide portion 4201 and the second needle-containing guide portion 4301 are splayed at the positions of the guide ports.

Referring again to fig. 4, in one particular pin-containing cube 40, the lead-out end of the pin-containing lead-out track is lower than the lead-in end of the pin-containing lead-in track along the lead-in direction. Specifically, the needle-containing discharge rail is disposed horizontally. More specifically, the slope of the first needle-containing curved surface 42011 in the direction along the leading-in direction is a negative value. The slope of the first needle-containing lead-out plane 42021 is 0. The slope of the second needle containing lead-out plane 43021 is 0.

Specifically, the needle-containing discharge rail is disposed horizontally. More specifically, the slope of the first needle-containing curved surface 42011 is positive. The slope of the first needle-containing lead-out plane 42021 is 0. The slope of the second needle containing lead-out plane 43021 is 0.

In one particular example, the first needle containing exit plane 42021 is horizontally disposed and the second needle containing exit plane 43021 is horizontally disposed.
