Description

Technical Field

[0001] The utility model relates to the technical field of stocking production, in particular to a tension regulating mechanism of a stocking knitting machine. Background Art

[0002] The tension adjustment mechanism of a hosiery machine is mainly responsible for controlling the tension of the yarn by adjusting the yarn delivery amount, which can prevent technical problems such as thread breakage during high-speed knitting operations. At present, many tension adjustment mechanisms achieve effective control of yarn tension by adjusting the lifting and lowering of the traction wheel. However, there are still some shortcomings, such as insufficient adjustment accuracy and slow response speed. During high-speed knitting, the tension adjustment mechanism must be able to quickly adapt to any changes in yarn tension. If the response speed is not fast enough, it may cause fluctuations in yarn tension, affecting knitting quality and production efficiency. Utility Model Content

The outer wall of one end of the round rod 213 is slidably plugged into the annular groove 131. A bidirectional threaded screw 222 is rotatably connected inside the square tube 211. The outer wall of the square rod 212 is screwed together with the outer wall of one side of the bidirectional threaded screw 222. The outer wall of the bidirectional threaded screw 222 is fixedly connected with bevel gear 223 at the positions on both sides of the center.
