Description

Technical Field

[0001] This utility model relates to the field of fiber processing technology, specifically to a tension traction device for DTY fiber processing. Background Technology

[0002] DTY fiber, short for low-elastic polyester yarn, is a type of textured polyester fiber. It is made from polyester chips (PET) as raw material, through high-speed spinning of pre-oriented polyester yarn (POY), followed by drawing and false twisting. It features a short process, high efficiency, and good quality. After the DTY fiber is processed, it needs to be wound up. In order to ensure that the density and compactness of the DTY fiber on the winding roller are equal, the tension of the DTY fiber needs to be adjusted during the winding process. Therefore, a traction device that facilitates the tension adjustment of the wound DTY fiber is needed.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN222433792U discloses a tension traction device for DTY fiber processing, comprising: a base plate, a base, a housing, and a movable rod.

A hydraulic cylinder is fixed to the middle of the lower end inside the housing. A hydraulic rod is movably installed at the middle of the upper end of the hydraulic cylinder. The lower side of one end of the movable rod is fixed to the upper end of the hydraulic rod. A second movable shaft is movably installed at the end of the movable rod opposite to the hydraulic rod. A fixing rod is fixed to the upper end of the housing located on the side of the through groove.

[0004] Although the existing technical solution described above achieves tension adjustment for wound DTY fibers, it can only adjust the movable rod, which has a limited range of motion in the through groove, and the position of the fixed rod cannot be adjusted, which also limits the range of tension adjustment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] A tension traction device for DTY fiber processing includes a base 1, a side plate 2 installed at one top end of the base 1, a groove formed at the top of the side plate 2, a connecting plate 3 installed on one side of the outer wall of the base 1, a take-up roller 4 installed at the end of the connecting plate 3 away from the base 1, multiple sets of guide rollers rotatably connected to the surface of the side plate 2, and universal wheels installed at the bottom corners of the base 1. The universal wheels are lockable universal wheels. A tension adjustment mechanism is installed on the side plate 2. The tension adjustment mechanism includes a synchronous adjustment component and a fine adjustment component. The synchronous adjustment component is used to initially adjust the approximate tension during conveying, and the fine adjustment component is used to fine-tune the tension after the synchronous adjustment component has made the approximate adjustment. In use, the device can initially adjust the approximate tension during conveying through the synchronous adjustment component, and the fine adjustment component can fine-tune the tension after the synchronous adjustment component has made the approximate adjustment. The structure is simple and easy to operate. The positions of the two sets of adjustment rollers 10 can be moved synchronously relative to each other or in opposite directions, which further increases the tension adjustment range. Moreover, when the tension adjustment range is small, there is no need to rotate the threaded rod 5; only the handle needs to be held for fine-tuning within a smaller range.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the synchronous adjustment assembly includes adjustment grooves on both sides of one side plate 2. Threaded rods 5 are rotatably connected to the inner side of the adjustment grooves. The threads on the outer sides of the two sets of threaded rods 5 are opposite. Adjustment blocks 6 are threadedly connected to the upper end of one set of threaded rods 5 and the lower end of the other set of threaded rods 5. The adjustment blocks 6 are slidably connected to the adjustment grooves. Operating rods are rotatably connected to both ends of the top of the grooves. Sprockets 7 are fixedly sleeved on one end of the outer side of the two sets of operating rods. The two sets of sprockets 7 are connected by a chain. A rotating wheel 8 is installed at the top of one set of sprockets 7. The other end of the operating rod extends into the inner side of the adjustment groove and is fixedly connected to one end of the threaded rod 5. First, when a larger tension adjustment is required, the rotating wheel 8 can be held and rotated. This, combined with the chain, drives both sets of sprockets 7 to rotate, which in turn drives the threaded rods 5 to rotate. This causes the two sets of adjustment blocks 6 to move in opposite directions within the adjustment grooves, increasing the adjustment range.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the fine-tuning assembly includes a fixed roller 9 installed on one side of the adjusting block 6. The other end of the fixed roller 9 is rotatably connected to an adjusting roller 10. The other end of the adjusting roller 10 is rotatably connected to a connecting rod 11. The outer side of the connecting rod 11 is rotatably connected to a positioning seat 12. Then, when the tension does not need to be adjusted over a large range, the handle can be held to move the pull-out seat 14, so that the extrusion plate 15 slides and extrudes the two sets of first springs 20 inside the extrusion groove, thereby driving the adjusting column 16 to be pulled out from the adjusting hole.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a horizontal plate 13 is installed between one side of the positioning seat 12 and the outer wall of the fixed roller 9. A pull-out seat 14 is slidably connected to one side of the positioning seat 12. The connecting rod 11 is slidably connected to the pull-out seat 14. An extrusion groove is opened inside the positioning seat 12 on the outside of the pull-out seat 14 and the connecting rod 11. An extrusion plate 15 is slidably connected to the inside of the extrusion groove. A first spring 20 is installed between both ends of one side of the extrusion plate 15 and the inner wall of the extrusion groove. The extrusion plate 15 is rotatably connected to the connecting rod 11. One end of the pull-out seat 14 is rotatably connected to one side of the extrusion plate 15. Furthermore, the handle can be twisted at this time. While twisting, the pull-out seat 14 will also rotate. In this way, the outer wall of the limiting block 17 abuts against the inner wall of the limiting groove, so that the connecting rod 11 is also rotated. This drives the adjusting roller 10 to rotate on the fixed roller 9, thereby driving the conveying roller 19 on the fixed frame to rotate together, adjusting the angle at which it supports the fiber, thereby achieving the effect of fine-tuning the tension.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, one side of the positioning seat 12 has multiple sets of adjustment holes arranged in a row. One side of the pull-out seat 14 is equipped with an adjustment column 16 that is slidably connected to the adjustment holes. The end of the pull-out seat 14 away from the positioning seat 12 is equipped with a handle. Limit grooves are provided on both sides of one end of the connecting rod 11. Two sets of limit blocks 17 that are slidably connected to the limit grooves are arranged on the inner wall of the pull-out seat 14. A magnetic block 18 is installed at one end of the adjustment column 16. An iron block that attracts the magnetic block 18 is embedded in the inner side of the adjustment hole. The top end of one set of adjustment rollers 10 and the other set of adjustment rollers 16 are connected in a row. A fixed frame is installed at one end of the bottom of each roller 10. The conveying roller 19 is rotatably connected to the inside of the fixed frame. Furthermore, after the adjustment is in place, the pull-out seat 14 can be released back by the elastic force of the two sets of first springs 20, so that the adjusting column 16 on it enters the corresponding adjusting hole. At the same time, the magnetic block 18 attracts the iron block to enhance the positioning effect. When the fixed frame and the conveying roller 19 rotate, they can pass through the area between the horizontal plate 13, the adjusting roller 10 and the fixed roller 9 without being obstructed. The adjustment range is further increased on the basis of the synchronous adjustment component.

[0027] The implementation principle of the tension traction device for DTY fiber processing in this application embodiment is as follows: When a large tension adjustment is required, the rotating wheel 8 can be gripped and rotated, which in turn drives the two sets of sprockets 7 to rotate, thereby driving the threaded rod 5 to rotate. This causes the two sets of adjusting blocks 6 to move in opposite directions within the adjusting groove, increasing the adjustment range. When a large tension adjustment is not required, the handle can be gripped and the pull-out seat 14 can be moved, causing the extrusion plate 15 to slide and extrude the two sets of first springs 20 within the extrusion groove. This causes the adjusting column 16 to be pulled out of the adjusting hole. At this time, the handle can be twisted, and the pull-out seat 14 will also rotate simultaneously, thus limiting the movement of the limit block. The outer wall of 17 abuts against the inner wall of the limiting groove, causing the connecting rod 11 to rotate as well, which in turn drives the adjusting roller 10 to rotate on the fixed roller 9, thereby driving the conveying roller 19 on the fixed frame to rotate together, adjusting the angle at which it supports the fiber, thus achieving the effect of fine-tuning the tension. After the adjustment is in place, the pull-out seat 14 can be released back by the elastic force of the two sets of first springs 20, so that the adjusting column 16 on it enters the corresponding adjusting hole. At the same time, the magnetic block 18 and the iron block attract each other, which enhances the positioning effect. When the fixed frame and the conveying roller 19 are rotating, they can pass through the area between the horizontal plate 13, the adjusting roller 10 and the fixed roller 9 without being blocked, further increasing the adjustment range on the basis of the synchronous adjustment component.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
