Knitting needle method of yarn change machine and yarn feeding mouth structure used thereof

Abstract

The invention discloses a method for needling a knitting needle of a yarn regulating machine and a feed nozzle structure thereof, belonging to the technical field of yarn regulating machine manufacture. The feed nozzle structure body of the yarn regulating machine is provided with a depressed area, wherein the lower edge of the depressed area is contacted with the middle position of a needle latch, while the other side surface of the depressed area is an inclined plane. The invention also provides the method for needling the knitting needle of the yarn regulating machine, comprising the following steps: the needle latch slightly opens at a certain angle, slides along the side surface of the feed nozzle; after the knitting needle slides a chute, the middle part of the needle latch is constantly contacted with the lower edge of the depressed area of the feed nozzle, so that clearance is reserved between the tip of the needle latch and the bottom surface of the depressed area of the feed nozzle; and the needle latch slides the inclined plane on the tail end of the depressed area to enter the next process. The method and the structure have the characteristic of safe needling, moreover, cooperation of the feed nozzle structure and the needling method can reduce consumption of the knitting needles, thereby reducing the defective rate of cloth.

Description

technical field [0001] The invention discloses a needle-moving method of a knitting needle of a thread-adjusting machine and a used yarn feeding nozzle structure, belonging to the technical field of thread-adjusting machine manufacturing. Background technique [0002] Knitting is a method of using knitting needles to weave yarns into coils and interlock them to form a piece of cloth. According to different process characteristics, knitting production is divided into two categories: weft knitting and warp knitting. The circular knitting machine is a device that feeds the yarn into the working needles of the circular weft machine sequentially from the weft direction, and then bends the yarn into loops sequentially through the loop forming parts, and interlocks each other to form a knitted fabric . The thread adjusting machine belongs to the type of circular weft knitting machine. The formation of weft knitted fabric generally goes through three stages of yarn supply, weaving ...

AI Technical Summary

Problems solved by technology

The knitting needle ① is attached to the yarn feeder ③, the gap between the two is between 0.5mm-1mm, and the length of the needle latch ② is about 4mm. When the machine runs at high speed and the yarn breaks, the needle latch ② will be closed by the old coil , but no new yarn is fed, but the equipment is still rotating. At this time, the needle latch is slightly opened at a certain angle and slides along the side of the yarn feeder ③. Generally, it will go through two stages, such as figure 2 and image 3 As shown, the first stage is the smooth plane A of the yarn feeder that slides past. At this stage, the latch ② of the knitting needle maintains an open angle, and the tip of the latch contacts with the smooth plane A so that the needle does not strike the needle; the second The stage is to pass through the chute ④ and slide over the yarn feeder ③. The existing yarn feeder ③ is set as an inclined plane B at one edge of the chute. Then it slides out from the arc surface of the yarn feeder ③. The setting of the inclined surface B above avoids the phenomenon of the needle latch ② being bumped to a certain extent. However, in the actual knitting process, the needle latch ② is often bumped and crooked. , the reason is as follows: when the knitting needle passes through the inclined surface of the yarn feeder chute, there will still be friction between the inclined surface and the needle latch, and the tip of the needle latch will be subjected to a force along the direction of machine reversal, which will easily make the needle latch crooked In severe cases, if the opening angle of the needle latch is too large and the reaction force received is large, the knitting needle will be broken, and then defective weaving will occur.

[0004] Knitting needles are high-precision accessories of knitting machines. Currently, the price of a knitting needle on the market is generally 2 to 6 yuan, and there are 1500-3000 knitting needles on a piece of equipment. With the structure of the yarn feeder, the knitting needles often have the phenomenon of crooked or broken needle latches, and repairing or replacing the knitting needles requires both manpower and time, which reduces the working efficiency of the knitting machine and is harmful to the user. cause very large property damage
