Description

A yarn tension compensation device Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a yarn tension compensation device. Background Technology

[0002] Yarn tension compensation devices are crucial components in textile equipment used to adjust and stabilize yarn tension. Uneven yarn tension results in inconsistent stretching during weaving, leading to variations in yarn thickness and affecting yarn evenness. Tension compensation ensures the yarn maintains appropriate and stable tension throughout the weaving process, preventing uneven thickness, increased hairiness, and other problems, thus guaranteeing consistent yarn strength and abrasion resistance.

[0003] Chinese patent application CN202420088998.4 discloses a yarn tension compensation device, which includes a rotating rod and threaded blocks threadedly connected to the rotating rod. When adjusting the tension compensation points of the yarn, rotating the rotating rod forward causes each pair of threaded blocks threaded to the rotating rod to move closer together. The corresponding hinged arms then push the ejector rod outward, and the tensioning wheel fixedly installed at the top of the ejector rod also pushes it outward. Tension compensation at each yarn tension compensation point can be achieved simply by rotating the rod, ensuring that all tension compensation points are tightened synchronously, eliminating the need for manual adjustment of each compensation point sequentially. However, this compensation device lacks a mechanism to prevent yarn slippage, making it prone to yarn slippage under dynamic tension adjustment or external force. Summary of the Invention

[0004] The main objective of this invention is to provide a yarn tension compensation device to solve the problem that existing compensation devices in related technologies do not have a mechanism to prevent yarn slippage, which can easily lead to yarn slippage under dynamic tension adjustment or external force.

[0039] The hanging rod part 2 includes a hanging rod 21, which passes through the compensating cylinder 11 and the piston plate 13. The hanging rod 21 is slidably connected to the compensating cylinder 11 and fixedly connected to the piston plate 13. The hanging rod 21 passes through the center of the spring 14.

[0040] The bottom of the hanging rod 21 is provided with a hanging port 4 on one side, and the counterweight 3 is hung on the hanging port 4.

[0041] As shown in Figure 7, the counterweight part 3 includes a tray 31, a column 32, a hanging ring 33, and several counterweight blocks 34. The column 32 is fixedly installed on the upper surface of the tray 31, the hanging ring 33 is installed on the top of the column 32, and the counterweight blocks 34 are all placed on the tray 31. The counterweight blocks 34 have notches, which are engaged with the column 32. Each counterweight block 34 is marked with its weight. The counterweight blocks 34 are added or removed from the tray 31 according to the yarn tension requirements.

[0042] As shown in Figures 3 and 6, the hanging rod part 2 also includes a yarn receiving part and a groove receiving part. The yarn receiving part includes a hanging hole 22 and a horizontal opening 23, and the groove receiving part includes an arc-shaped groove 24, a top groove 25 and a stop block 26.

[0043] Hanging hole 22 is located at the upper end of hanging rod 21. Horizontal opening 23 is located on one side of hanging rod 21 and communicates with hanging hole 22. Arc groove 24 is located inside hanging rod 21 below hanging hole 22 and communicates with hanging hole 22.
