Description

Technical Field

[0001] This utility model relates to the field of knitting machine heart technology, and more specifically, to a knitting machine heart with high-efficiency yarn supply. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, work by using a series of knitting machine accessories to weave various knitted fabrics. In this machine, yarn moves smoothly along the weft direction, sequentially bending into loops and interlocking to ultimately form the familiar knitted fabric. The heart of the knitting machine usually refers to the knitting mechanism, the core component of the circular knitting machine. It mainly consists of a cylinder, needles, cams, cam seats, and sinkers. These components work together to control the up-and-down movement of the needles, completing the entire process of knitting fabric from yarn. However, existing knitting machines are not conducive to a uniform yarn supply, affecting the quality of the knitted fabric. Therefore, we propose a knitting machine heart with a highly efficient yarn supply. Utility Model Content

[0003] In view of the problems mentioned in the background art above, the purpose of this utility model is to provide a high-efficiency yarn feeding core for knitting machines.

[0004] To solve the above problems, the present invention adopts the following technical solution:

A first rubber roller is rotatably connected to one L-shaped bracket, and a second rubber roller is rotatably connected to the other L-shaped bracket. A dual-axis motor is fixedly installed on the top surface of the other L-shaped bracket. One output shaft of the dual-axis motor is connected to the top end of the second rubber roller shaft via a coupling. A spur gear is fixedly sleeved on the other output shaft of the dual-axis motor. The top end of the first rubber roller shaft extends to the top of the L-shaped bracket and is fixedly sleeved with another spur gear. The two spur gears mesh with each other.

Then, the two electric push rods 6 are activated to drive the two L-shaped brackets 7 to move closer together, causing the first rubber roller 8 and the second rubber roller 9 on the two L-shaped brackets 7 to squeeze the yarn. At the same time, the two spur gears 11 mesh with each other. Finally, after the yarn feeding mechanism releases the yarn, the dual-shaft motor 10 is activated to drive the second rubber roller 9 and the spur gears 11 to rotate clockwise. Through the meshing transmission between the two spur gears 11, the first rubber roller 8 rotates counterclockwise. The second rubber roller 9 and the first rubber roller 8 provide driving force for the yarn, so as to efficiently and uniformly feed yarn to the braiding mechanism.
