Description

Technical Field

[0001] This utility model relates to a yarn tension compensation and anti-twist device, belonging to the field of textile yarn. Background Technology

[0002] In the spinning process, twisting the yarn around its axis increases its twist, satisfying certain physical properties of the yarn. This twisting enhances the yarn's strength, elasticity, elongation, luster, and hand feel, directly impacting the fabric's style and the garment's performance. It is a crucial criterion for product grading. However, varying yarn feed rates and tension during spinning can cause yarn back-twist, hindering normal weaving and disrupting production. The high tension during back-winding necessitates cleaning, disrupting operation. While many devices exist to eliminate yarn back-twist, their application is limited, primarily suited for weft knitting. Therefore, a more versatile and effective yarn tension compensation and anti-twist device is urgently needed. Summary of the Invention

[0003] Based on the problems described in the background, the problem that this utility model aims to solve is:

[0004] Design an effective and widely adaptable yarn tension compensation and anti-twist device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A yarn tension compensation and anti-twist device includes a yarn baffle, an anti-twist adjuster, a terminal yarn guide plate, and a U-shaped bracket. The yarn baffle has a yarn guide eye. The anti-twist adjuster includes symmetrical clamps and a compression spring. The terminal yarn guide plate has a yarn guide eye. The yarn passes through the yarn guide eye of the yarn baffle to the anti-twist adjuster, and then through an opening between the symmetrical clamps to the downstream process. The symmetrical clamps are divided into fixed plates and squeezing plates, which are symmetrically arranged. The yarn passes through the gap between the squeezing plates and the fixed plates. The squeezing plates squeeze the yarn to eliminate twist through the elastic force of the compression spring.

[0007] After adding this utility model device between the spool and the yarn feeder of the circular knitting machine, the originally loose yarn becomes taut and tension-compensated between the symmetrical clamps and the yarn feeder, making it difficult to twist back. Figure 3 It can be seen that the distance between the spool and this utility model is close, so no large twists will be formed. The twists can be easily untangled by the symmetrical clamps.

[0008] Preferably, the compression spring is a tower-shaped compression spring, including a support rod and a spring. The bottom end of the support rod is fixed to the bottom surface of the device. The spring is sleeved on the surface of the support rod, with one end of the spring fixedly connected to the upper end of the support rod and the other end connected to the compression plate. The fixing plate is fixedly sleeved on the support rod, and the compression plate is positioned above the fixing plate and movably sleeved on the support rod. The compression plate is connected to the spring. The structure is simple and durable, and can effectively eliminate twist.

[0009] Preferably, the yarn guide eye is provided with a wear-resistant sleeve.

[0010] The beneficial effects of this utility model are:

[0011] This utility model device is simple to operate and easy to use. It can effectively prevent yarn back-twisting from causing fabric downgrade, reduce secondary processing caused by yarn back-twisting, reduce needle damage, save time and effort, save costs, and improve production efficiency.

Detailed Implementation

[0016] Example 1

[0017] A yarn tension compensation and anti-twist device includes a yarn baffle plate 1, an anti-twist adjuster, a terminal yarn guide plate 4, and a U-shaped bracket 6. The yarn baffle plate 1 has a yarn guide eye 5. The anti-twist adjuster includes symmetrical clamping plates 2 and a compression spring 3. The terminal yarn guide plate 4 has a yarn guide eye 5. The yarn passes through the yarn guide eye 5 of the yarn baffle plate 1 to the anti-twist adjuster, and passes between the symmetrical clamping plates 2 to the downstream process. The symmetrical clamping plates are divided into a fixing plate 21 and a squeezing plate 22. The squeezing plate 22 and the fixing plate 21 are arranged symmetrically. The yarn passes through the gap between the squeezing plate 22 and the fixing plate 21. The squeezing plate 22 squeezes the yarn to eliminate twist through the elastic force of the compression spring 3.

[0018] The compression spring 3 is a tower-shaped compression spring, including a support rod 31 and a spring 32. The bottom end of the support rod 31 is fixed to the bottom surface of the device. The spring 32 is sleeved on the surface of the support rod 31, and one end of the spring 32 is fixedly connected to the upper end of the support rod 31, while the other end is connected to the extrusion plate 22. The fixing plate 21 is fixedly sleeved on the support rod 31, and the extrusion plate 22 is disposed above the fixing plate 21 and movably sleeved on the support rod 31. The extrusion plate 22 is connected to the spring 32.
