Detailed Description

The present application is described in further detail below with reference to figures 1-5.

For convenience of understanding, the structure of the conventional four-needle six-thread sewing machine will be briefly described. Referring to fig. 1 and 2, the four-needle six-thread sewing machine includes a machine body 1, a machine head 2 mounted on the machine body 1, and a cross arm 3 integrally formed on the machine body 1 and horizontally extending to a position right below the machine head 2, wherein the cross arm 3 is located right below the machine head 2 and internally mounted with an active cloth feeding tooth, and is mainly used for driving cloth placed on the cross arm 3 to feed. The machine body 1 is provided with a pay-off roller 11 and a lead frame 12; the machine head 2 is provided with a cutter, a sewing needle and a presser foot; the cutter is mainly used for trimming the fed cloth; the thread on the pay-off roller 11 is connected with a needle through a lead frame 12 and is mainly used for sewing cloth; the presser foot is mainly used for being matched with the cloth feeding teeth so that cloth can be fed smoothly.

The xarm 3 is close to the banding director 4 that the cloth feed direction arranged of installing on the surface of sending the cloth tooth, add man-hour, the staff carries out preliminary fixed to two blocks of cloth through the presser foot, then stand the limit that two blocks of cloth need be made up respectively and lean on in the both sides of director 4, along with the feeding of cloth, the upper portion excision of cutter with two blocks of cloth, the in-process of feeding, the staff need drag the cloth through the hand and move together with it in order to last the taut flat and straight of cloth, after the excision, the seam is made up to the part after the excision, the in-process of making up, the part that two cloth stand is though pressed down, nevertheless can produce in the flat and piled up in 0.6mm wide flat and sew up, be similar to in limited space compression, lead to making up the back and inside uplift towards the clothes, make the seam.

Therefore, the embodiment of the application discloses a narrow four-needle six-thread sewing machine. Referring to fig. 3, the narrow four-needle six-thread sewing machine comprises a machine body 1, a machine head 2 installed on the machine body 1 for sewing and trimming cloth, and a cross arm 3 integrally formed on the machine body 1 and horizontally extending to the position under the machine head 2, wherein the cross arm 3 is located inside the position under the machine head 2 and is provided with a cloth feeding tooth for driving the cloth to feed, the upper surface of the cross arm 3 is a horizontal plane, a distributor 5 and a limiting guider 6 are installed on the upper surface of the cross arm 3 close to the position of the machine head 2, the distributor 5 and the limiting guider 6 are arranged along the feeding direction of the cloth in sequence and in a left-right staggered mode, namely, one is located on the left hand side of a worker, and the other is located.

The distributor 5 is mainly used for erecting a piece of cloth, so that the machine head 2 can cut the edge of the piece of cloth, and the other piece of cloth is limited at the same time, so that the machine head 2 can sew the two pieces of cloth. The limiting guide device 6 is mainly used in cooperation with the distributor 5, so that the probability of burrs and exposed seams of the cloth in the subsequent trimming and sewing processes due to deviation of the cloth is reduced when the cloth is fed smoothly.

Referring to fig. 3 and 4, the distributor 5 includes a supporting plate 51 fixedly mounted on the upper surface of the cross arm 3 and extending along the width direction of the cross arm 3, and a vertical plate 52 integrally connected to one end of the supporting plate 51 close to the center line of the cross arm 3, the supporting plate 51 and the vertical plate 52 are L-shaped, one side of the vertical plate 52 away from the supporting plate 51 is a vertical surface 53 perpendicular to the upper surface of the cross arm 3, and the vertical surface 53 is used for positioning the tiled cloth. An arc surface 54 is processed between the vertical plate 52 and the supporting plate 51, and the arc surface 54 is used for supporting the cloth to be erected. One side edge of the supporting plate 51 far away from the machine head 2 is processed with a slope 55, the slope 55 deviates from the cloth feeding direction and is gradually reduced, the minimum thickness of the slope 55 is 0.5-1.5mm, the structural design is mainly convenient for the hand of a worker to slide along the upper surface of the cross arm 3 so as to feed along with the cloth, and the damage caused by the finger poking on the side edge of the supporting plate 51 in the feeding process is avoided.

Spacing director 6 is including installing at 3 upper surfaces of xarm and along 3 width direction extension's of xarm bottom plate 61 to and bend the shaping and be close to the board 62 of bending of 5 one ends in bottom plate 61, bend board 62 through bend after and form centre gripping space 63 between the bottom plate 61, this centre gripping space 63 not only can lead the cloth of tiling, can also carry out the spacing in vertical side to the cloth of tiling.

Referring to fig. 5, in order to ensure that the spacing guide 6 and the distributor 5 can continuously guide the tiled cloth, the inner curved wall surface of the bending part of the spacing guide 6 and the vertical surface 53 of the vertical plate 52 need to be located on the same straight line.

The implementation principle of the embodiment of the application is as follows: before sewing, a worker lays a part of one piece of cloth to be sewn on the cross arm 3, penetrates through the clamping space 63 of the limiting guide 6, supports the edge of the piece of cloth on the vertical surface 53 of the vertical plate 52 while penetrating through the clamping space, and then puts the edge of the other piece of cloth on the distributor 5 along the arc surface 54 and enables the edge of the piece of cloth to be higher than the vertical plate 52; the two pieces of cloth are respectively dragged by two hands and are tensioned and straightened, specifically, the cloth is dragged by a thumb and a forefinger, and in the feeding process of the cloth, a middle finger and a ring finger cling to the arc surface 54 and the vertical surface 53 of the vertical plate 52 to slide along the upper surface of the cross arm 3, so that the positioning effect is mainly played; after the cutter on the machine head 2 cuts the upright cloth, the cloth is inclined towards one side of the tiled cloth to form a vertically overlapped flat structure; the seam on the aircraft nose 2 is made up to two fabrics immediately, because two fabrics are the level and smooth structure of overlap from top to bottom, consequently can not appear piling up, the circumstances of uplift after making up, and the flat seam is thinner, has improved wearer's travelling comfort greatly.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
