Description

Technical Field

[0001] This utility model relates to the field of yarn traction technology, specifically a yarn traction device for textile machines. Background Technology

[0002] Yarn is a textile product made from various textile fibers processed to a certain fineness. It is used for weaving, rope making, thread making, knitting, and embroidery. Yarn is classified into staple fiber yarn and continuous filament yarn. Yarn fineness is expressed in various ways, such as count, metric count, imperial count, denier, etc. (see count). Yarn twist is expressed as the number of twists per meter or inch. Wool yarn is generally used to weave sweaters, trousers, vests, scarves, hats, gloves, and to knit various spring and autumn clothing items. Besides warmth, it also serves a decorative purpose. When textile machines produce yarn, a traction mechanism is needed to pull the yarn to prevent it from shifting. However, in actual production, multiple different yarns need to be transported simultaneously, which can easily lead to yarn shifting and tangling, affecting production. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a yarn traction device for textile machines to solve the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a yarn traction device for a textile machine, comprising a traction frame, a lower guide traction roller rotatably mounted on the traction frame, the lower guide traction roller having a plurality of annular grooves, the plurality of annular grooves being equally spaced along the axial direction of the lower guide traction roller, an upper guide traction roller being mounted above the lower guide traction roller, the upper guide traction roller having a degree of freedom to move along the height direction of the traction frame, a plurality of guide teeth being fixedly sleeved on the upper guide traction roller, the plurality of guide teeth corresponding one-to-one with the plurality of annular grooves, the guide teeth extending into the annular grooves, and a gap being formed between the guide teeth and the annular grooves for yarn to pass through.

[0006] Furthermore, each of the lifting seats is provided with a corresponding cylinder, the cylinder body of which is vertically mounted on the traction frame, and the output shaft of the cylinder is connected to the lifting seat.

[0007] Furthermore, it also includes a yarn clamping assembly. The traction frame and the yarn clamping assembly are arranged sequentially along the yarn conveying direction. The yarn clamping assembly includes an upper yarn clamping roller and a lower yarn clamping roller. The yarn passes between the upper yarn clamping roller and the lower yarn clamping roller. The upper yarn clamping roller moves closer to or away from the lower yarn clamping roller to clamp the yarn.

[0008] Furthermore, the wire clamping assembly also includes a wire clamping bracket, the lower wire clamping roller is fixedly mounted on the wire clamping bracket, and the upper wire clamping roller is slidably disposed on the wire clamping bracket.

Detailed Implementation

[0015] Example 1

[0016] like Figure 1 and Figure 2As shown, a yarn traction device for a textile machine includes a traction frame 1. A lower guide traction roller 2 is rotatably mounted on the traction frame 1. The lower guide traction roller 2 has several annular grooves 3, which are evenly spaced along the axial direction of the lower guide traction roller 2. An upper guide traction roller 4 is positioned above the lower guide traction roller 2 and has the freedom to move along the height direction of the traction frame 1. Several guide teeth 5 are fixedly fitted onto the upper guide traction roller 4, each guide tooth 5 corresponding to one of the annular grooves 3. The guide teeth 5 extend into the annular grooves 3, forming a gap between the guide teeth 5 and the annular grooves 3. The gap for yarn passage is provided. First, the yarn is arranged, and the upper guide traction roller 4 moves upward to create a large operating space between the upper guide traction roller 4 and the lower guide traction roller 2. The yarn passes through the annular groove 3. Each yarn is assigned a corresponding annular groove 3 to achieve individual conveying of each yarn. Then, the upper guide traction roller 4 moves downward so that the guide teeth 5 extend into the annular groove 3 to prevent the yarn from detaching from the annular groove 3. The yarn is guided and pulled through the gap formed by the guide teeth 5 and the annular groove 3. This allows for the simultaneous distinguishing and conveying of multiple different yarns, avoiding the problem of entanglement caused by conveying deviation.

[0017] Example 2

[0018] Based on Example 1, such as Figure 1 and Figure 2 As shown, it also includes a yarn clamping assembly. The traction frame 1 and the yarn clamping assembly are arranged sequentially along the yarn conveying direction. The yarn clamping assembly includes an upper yarn clamping roller 8 and a lower yarn clamping roller 9. The yarn passes between the upper yarn clamping roller 8 and the lower yarn clamping roller 9. The upper yarn clamping roller 8 moves closer to or away from the lower yarn clamping roller 9 to clamp the yarn. When the textile machine completes one production cycle, it needs to cut the yarn. At this time, the yarn is easy to fall back and get out of the annular groove 3. For this reason, a yarn clamping assembly is set up. Before cutting the yarn, the upper yarn clamping roller 8 moves closer to the lower yarn clamping roller 9 so that the upper yarn clamping roller 8 presses the yarn tightly on the lower yarn clamping roller 9 to prevent the yarn from falling back and avoid the yarn from falling out of the annular groove 3.

[0019] Example 3

[0020] Based on Embodiment 2, the yarn clamping assembly further includes a yarn clamping bracket 10. The lower yarn clamping roller 9 is fixedly installed on the yarn clamping bracket 10, and the upper yarn clamping roller 8 is slidably installed on the yarn clamping bracket 10. Both ends of the upper yarn clamping roller 8 are fixedly connected to yarn clamping slides 11. Each yarn clamping slide 11 is correspondingly provided with a yarn clamping cylinder 12. The cylinder body of the yarn clamping cylinder 12 is vertically installed on the yarn clamping bracket 10. The telescopic shaft of the yarn clamping cylinder 12 is connected to the yarn clamping slide 11. The telescopic movement of the yarn clamping cylinder 12 drives the upper yarn clamping roller 8 to move closer to or away from the lower yarn clamping roller 9, thereby realizing the clamping and releasing of the yarn.

[0021] Example 4

[0022] Based on Embodiment 3, both ends of the upper guide traction roller 4 are rotatably connected to lifting seats 6. The lifting seats 6 are slidably installed on the traction frame 1. Each lifting seat 6 is correspondingly provided with a cylinder 7. The cylinder body of the cylinder 7 is vertically installed on the traction frame 1. The output shaft of the cylinder 7 is connected to the lifting seat 6. The extension and retraction of the cylinder 7 drives the lifting seat 6 to move up and down, which facilitates the initial insertion of the yarn into the gap formed by the guide tooth 5 and the annular groove 3.
