Background

The artificial wool is a wool fabric similar to animal fur and formed by processing artificial fiber through knitting and weft knitting, and people prefer the wool fabric with longer wool length along with the improvement of aesthetic requirements of people. The length of the knitted long pile fabric is determined by the length of the thread between the upper knitting needle and the lower knitting needle at the lowest point.

The silk threads of the silk thread barrel are conveyed to the circular knitting machine and then are alternately hung between the upper knitting needle and the lower knitting needle; the circular knitting machine rotates to enable the lower knitting needle to rise to hook the silk thread under the driving of the triangle, and then the lower knitting needle descends to pull the silk thread downwards; during the process of pulling down the front knitting needle, the back knitting needle rises to hook the back section of silk thread, therefore, the next knitting needle needs to slide through the hook part of the back knitting needle when pulling down the silk thread continuously; as the lower knitting needles descend, more and more lower knitting needles on the rear side of the lower knitting needles hook the yarns, so that the resistance of the lower knitting needles on the front side to pull the yarns is larger and larger; the long-wool fabric needs a long length for pulling the silk thread down, namely, the lower knitting needle needs to descend for a long distance, the structure of the existing circular knitting machine guides the lower knitting needle to descend through a triangle, the triangle guides the lower knitting needle to descend through a track groove, the slope of an inclined track groove cannot be too large, the speed for guiding the lower knitting needle to descend is low, when the lower knitting needle descends to a lower position, a large number of lower knitting needles are hung on the silk thread on the rear side of the circular knitting machine, the resistance for continuously pulling the silk thread down becomes very large, the silk thread cannot be pulled completely, and the silk thread can be broken after the maximum tensile force which can be borne by the silk thread is exceeded.

The circular knitting machine for knitting the ultra-long fluff fabric needs to use the lower knitting needle 4 with longer length, and as the lower knitting needle 4 is longer in length, the direct stamping deformation is larger, the needle body is easy to be excessively bent, and further the circular knitting machine cannot be produced by adopting a stamping forming process; the lower knitting needle of the integrated structure can meet the use requirement only by adopting a wire-cutting mode for manufacturing, the cost of the wire-cutting manufacturing is high, and the production efficiency is low.

The lower knitting needle 4 in the application adopts two-section separated production, the lengths of the first needle body 42 and the second needle body 43 are shorter, so that the lower knitting needle can be produced by adopting a stamping mode with low cost and high efficiency under the condition of ensuring the quality, a detachable connection mode that the clamping block 44 and the clamping groove 45 are correspondingly clamped and embedded is adopted between the first hooking section 421 of the first needle body 42 and the second hooking section 431 of the second needle body 43, on a circular knitting machine, the lower knitting needle 4 is positioned between the two inserting sheets, so that the left and right sides of the first needle body 42 and the second needle body 43 are limited and can not move relatively, namely the first needle body 42 and the second needle body 43 of the lower knitting needle 4 can not be separated from the left and right side surface directions in the working process, because at least one clamping groove 45 has a necking structure gradually shrinking from inside to outside, the first needle body 42 and the second needle body 43 can not be separated from the front and back directions after being clamped and embedded, so that the two-section knitting needle body 4 can be ensured to be kept in the integral state in the working process, the working process is reliable.

A method for weaving a super-long plush fabric comprises the following steps:

step one, with the rotation of the upper dial 1, the silk thread of the silk thread cylinder is hooked by each upper knitting needle 2 and pulled out;

step two, along with the rotation of the lower dial 3, the butt 41 of the lower knitting needle 4 enters the ascending rail groove 51 of the triangle 5 and slides upwards along the ascending rail groove 51, so that the lower knitting needle 4 ascends to hook the silk thread of the upper knitting needle 2;

thirdly, with the rotation of the lower dial 3, the lower knitting needle 4 hooking the silk thread is separated from the ascending track groove 51 of the triangle 5 and is pulled downwards under the action of the spring 6, after the lower knitting needle 4 descends for a certain distance, the butt 41 of the lower knitting needle firstly falls to the high-position end of the inclined straight surface 521 of the guide slope 52 to be propped against, at the moment, only a few upper knitting needles 2 hook the silk thread at the rear section of the hooking position, so that the resistance of the downward pulling of the silk thread is small, the silk thread can slide relative to the hooking position of the upper knitting needle 2 and is pulled downwards, and the silk thread is quickly pulled downwards for a certain distance under the condition of small resistance;

step four, along with the rotation of the lower dial 3, under the action of the pull-down force of the spring 6, the lower knitting needle 4 slides downwards along the inclined straight surface 521 of the guide slope 52, and then smoothly moves to the horizontal guide surface 53 through the arc transition surface 522, namely the lower knitting needle 4 keeps a height unchanged state to perform transverse movement after descending to the lowest position, because the spring 6 is adopted as the power for pulling the lower knitting needle 4, the guide slope 52 plays a supporting role, therefore, the slope of the inclined straight surface 521 of the guide slope 52 can be designed to be larger, and under the condition that the transverse displacement of the lower knitting needle 4 is shorter, the lower knitting needle 4 descends from the high position to the low position and pulls a section of filament yarn.

In the process that the lower knitting needle 4 descends through the guide slope 52, because the transverse displacement of the lower knitting needle 2 is short, only one to two other lower knitting needles 4 on the rear side of the lower knitting needle 4 catch the silk thread, the resistance to the pulling of the silk thread is not large, the silk thread can slide relative to the catching positions of the upper knitting needles 2 and the lower knitting needles 4 and can be pulled down, and the situation that the silk thread is excessively tightened and broken is avoided.

The guide ramp 52 is provided for: because the lower knitting needle 4 is pulled down for a long distance, the spring is pulled down to make the lower knitting needle 4 do the accelerated descending action, if the guide slope 52 is not arranged, the butt 41 will impact on the flat guide surface 53 of the cam 5 at a high speed when the lower knitting needle 4 descends to the lowest position, the butt 41 is easily damaged by high impact force, and the needle drop can happen; when the guiding slope 52 is provided, the needle butt 41 firstly falls to the high-position end of the inclined straight surface 521 of the guiding slope 52 to be abutted against, at this time, the descending speed of the lower knitting needle 4 is not large, the impact force of the needle butt 41 is small and within a bearable range, and then the needle butt 41 is guided to slide downwards through the guiding slope 52, so that the needle butt 41 can be in smooth transition, the slope of the inclined straight surface 521 is large, and the lower knitting needle 4 can also reach the lowest position in a short time.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
