Description

Technical Field

[0001] This application relates to the field of textile drawing frame technology, and in particular to an automatic sliver cutting device for textile drawing frames. Background Technology

[0002] The original meaning of textiles comes from the general term for spinning and weaving. However, with the continuous development and improvement of the knowledge system and discipline of textiles, especially after the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, it is no longer just about traditional hand spinning and weaving. It also includes nonwoven technology, modern three-dimensional weaving technology, modern electrostatic nano-web forming technology, etc., to produce clothing, industrial and decorative textiles. In the textile process, drawing frames are required.

[0003] A search revealed that patent document CN221797777U discloses an automatic sliver cutting device for a textile drawing frame. The device comprises a base plate, on the top of which are sequentially mounted a positioning component for positioning the material, a clamping mechanism for holding the material, a limiting component for limiting the material's position, a conveying component for conveying the material, and a cutting component for cutting the material. The clamping mechanism is included. This relates to the field of automatic sliver cutting technology. Compared to the prior art, this application, through its clamping mechanism, can automatically limit and clamp the material as it passes through the positioning ring, and then directly adjust the length of the material, making its operation simpler.

[0004] In practical use, it was found that the existing device cannot clamp the sliver after drawing, which easily leads to the problem of the sliver becoming loose after cutting. Therefore, we proposed an automatic sliver cutting device for textile drawing machines to solve the above problems. Utility Model Content

[0038] Specifically, the bidirectional mechanism includes a bidirectional screw 13 and two screw seats 14. The same bidirectional screw 13 is rotatably installed on the inner wall of the front side and the inner wall of the rear side of the base box 1. Two screw seats 14 are threaded on the bidirectional screw 13. The screw seats 14 are slidably connected to the corresponding seat holes 23. A sliding mechanism is provided between the screw seats 14 and the base box 1.

[0039] Specifically, the sliding mechanism includes a slider 19 and a groove 20. The bottom of the screw seat 14 is provided with a slider 19, and the bottom inner wall of the bottom box 1 is provided with a groove 20. The slider 19 and the groove 20 are slidably connected.

[0040] Specifically, the cutting mechanism includes a lifting seat 10 and a cutter 11. The lifting seat 10 is fixedly installed on the output shaft of the hydraulic cylinder 9, and the cutter 11 is fixedly installed at the bottom of the lifting seat 10. A gear mechanism is provided between the lifting seat 10 and the bidirectional screw 13.

[0041] Specifically, the gear mechanism includes a gear 17 and a rack plate 18. The gear 17 is fixedly sleeved on the bidirectional screw 13. The gear 17 is located on the front side of the corresponding screw seat 14. The rack plate 18 is fixedly installed on the left side of the lifting seat 10.

[0043] Specifically, a cutting groove 12 is provided on the inner wall of the top of the strip holder 4. The cutting groove 12 is located to the right of the thickness sensor 22, and the cutter 11 is adapted to the cutting groove 12.

[0044] Specifically, two slide rods are fixedly installed on the inner wall of the top of the mounting bracket 3, the output shaft of the hydraulic cylinder 9 is located between the two slide rods, and the lifting seat 10 is slidably sleeved on the slide rods.

[0045] Specifically, the clamping mechanism includes two clamping seats 15 and two clamping pads 16. Two clamping seats 15 are slidably installed on the top of the base box 1.

[0046] In this application, during operation, the sliver after being drawn by the drawing device 2 is first passed through the sliver break holder 4 and fixed on the conveyor roller 7. By starting the motor 6, the sliver can be conveyed to the right. The thickness sensor 22 on the inner wall of the rear side of the sliver break holder 4 monitors the thickness information of the sliver in real time and transmits the data to the controller 21. When the thickness sensor 22 detects an abnormal sliver thickness (too thick or too thin), the controller 21 receives the signal and performs a judgment. If it is determined that the sliver needs to be broken, the controller 21 first controls the motor 6 to stop the rotation of the conveyor roller 7 and stops the sliver conveying. Then, the controller 21 starts the hydraulic cylinder 9 on the top of the mounting frame 3. The output shaft of the hydraulic cylinder 9 drives the lifting seat 10 to slide along the inner wall of the top of the mounting frame 3. As the rod moves downward, the cutter 11 at the bottom of the lifting seat 10 descends accordingly. During the descent, the rack plate 18 on the left side of the lifting seat 10 meshes with the gear 17 fixedly sleeved on the bidirectional screw 13. When the lifting seat 10 descends, the rack plate 18 drives the gear 17 to rotate, thereby causing the bidirectional screw 13 to rotate. This drives the two screw seats 14 to move closer to each other, which in turn drives the clamping seat 15 and the clamping pad 16 to move closer to the strip. This allows the strip to be squeezed and fixed by the clamping pad 16, preventing the strip from becoming loose after cutting. At the same time, the cutter 11 finally descends into the cutting groove 12 on the inner wall of the top of the strip cutting seat 4, thus cutting the strip.
