DETAILED DESCRIPTION

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

[0021] like Figures 1-6 As shown, a take-up mechanism for a large circular knitting machine includes a mounting frame. The mounting frame includes a base 1. Supporting walls 1-2 and 2-3 are respectively connected to the left and right sides of the upper part of the base 1, and the supporting walls 1-2 and 2-3 are perpendicular to the base 1. Rotating seats 1-5 and 2-7 are respectively provided on the supporting walls 1-2 and 2-7. Fixing components 6 and mounting components 8 are rotatably installed in the rotating seats 1-5 and 2-7, respectively. The fixing component 6 includes a rotating shaft 12. One end of the rotating shaft 12 near the take-up roller 10 is connected to a turntable 11. The other end of the rotating shaft 12 passes through the rotating seat 1-5 and is connected to a driven wheel 13. A limiting groove 17 is formed on the side of the turntable 11 near the take-up roller 10. Limiting blocks 18 are connected to both ends of the take-up roller 10. The cross-section of the limiting blocks 18 is rectangular. The cross-sectional shape of the limiting groove 17 matches the limiting blocks 18, and the limiting blocks 18 can be inserted into the limiting groove 17 for installation. Mounting component 8 includes mounting sleeve 19 and cover plate 20 slidably disposed on the upper part of mounting sleeve 19. Cover plate 20 and mounting sleeve 19 can be relatively fixed together by limiting component. Mounting sleeve 19 has mounting groove 21 on the side near take-up roller 10. The shape of mounting groove 21 matches limiting block 18. When installing take-up roller 10, cover plate 20 can be slid away from mounting groove 21 to expose mounting groove 21. Part of limiting block 18 at the end of take-up roller 10 near turntable 11 is inserted into limiting groove 17. Then, limiting block 18 at the end of take-up roller 10 near mounting sleeve 19 is inserted into mounting groove 21 from the exposed opening. During this process, limiting block 18 at the end of take-up roller 10 near turntable 11 can be fully inserted into limiting groove 17. Then, by sliding the cover plate 20, the cover plate 20 covers the top of the mounting groove 21, thereby completing the locking and fixing of the limiting block 18 in the mounting groove 21, and thus completing the installation of the take-up roller 10. When disassembling the take-up roller 10, slide the cover plate 20 to expose the upper opening of the mounting groove 21, and remove the limiting block 18 of the take-up roller 10 near the mounting sleeve 19 from the opening of the mounting groove 21. The limiting block 18 of the take-up roller 10 near the turntable 11 can also be brought out from the limiting groove 17, thereby completing the disassembly of the take-up roller 10.

[0022] The bearings are arranged between the fixing member 6 and the rotating seat 1, and between the rotating seat 2 and the mounting member 8 to complete the mounting. The limiting strips are arranged on the rotating shaft 12 at positions on both sides of the rotating seat 1, and the limiting strips are arranged on the mounting sleeve 19 at positions on both sides of the rotating seat 2 to limit the axial movement of the rotating shaft 12 and the mounting sleeve 19.

[0023] The driving member is mounted on the support wall 1, and the driving member comprises a driving motor 14. The driving motor 14 is drivingly connected with a driving wheel 16. One end of the rotating shaft 12 located outside the support wall 1 is connected with a driven wheel 13. The driven wheel 13 and the driving wheel 16 are connected. The driving motor 14 drives the driving wheel 16. The driving wheel 16 drives the driven wheel 13 through the transmission belt 15. The driven wheel 13 drives the rotating disc 11 through the rotating shaft 12. Thus, the rotating disc 11 drives the cloth collecting roller 10 to rotate to complete the winding.

[0024] The two cloth guide rollers 4 are rotatably arranged between the support wall 1 and the support wall 2. The two cloth guide rollers 4 are arranged in parallel and at the same height. The cloth collecting roller 10 is located below the two cloth guide rollers 4. The cloth is guided into the two cloth guide rollers 4, which facilitates the winding of the cloth collecting roller 10.

[0025] The cloth spreading roller 9 is rotatably arranged between the cloth guide rollers 4 and the cloth collecting roller 10 between the support wall 1 and the support wall 2. The cloth spreading roller 9 is provided with two spiral grooves on both sides. The spiral grooves on both sides are opposite in rotation direction. The two spiral grooves opposite in rotation direction are arranged to spread the cloth when the cloth passes through the cloth spreading roller 9, so that the cloth wound by the cloth collecting roller 10 is not prone to wrinkles.

[0026] The sliding groove 22 is formed on one side of the upper portion of the mounting sleeve 19 away from the mounting groove 21. The sliding groove 22 is arranged along the axial direction of the mounting sleeve 19. The lower portion of the mounting groove 21 is connected with the sliding block 23. The sliding block 23 is slidingly arranged in the sliding groove 22. The sliding groove 22 and the sliding block 23 are matched to limit the sliding of the cover plate 20 along the axial direction of the mounting sleeve 19.

[0027] The limiting member comprises the mounting cylinder 27 mounted on the upper portion of the mounting groove 21. The mounting cylinder 27 is hollow. The mounting cylinder 27 is provided with the top cover 28 on the upper portion. The mounting cylinder 27 is provided with the fixing pin 26. The mounting sleeve 19 is provided with the fixing hole 24. The mounting groove 21 is provided with the through hole 25. The fixing hole 24 and the through hole 25 are arranged along the radial direction of the mounting sleeve 19. When the cover plate 20 is moved to the position on the mounting sleeve 19, the through hole 25 and the fixing hole 24 are communicated. The lower end of the fixing pin 26 can pass through the through hole 25 and be inserted into the fixing hole 24. The portion of the fixing pin 26 located in the mounting cylinder 27 is provided with the limiting ring 29. The mounting cylinder 27 is provided with the spring 30. One end of the spring 30 abuts against the limiting ring 29. The other end of the spring 30 abuts against the top cover 28. The end of the fixing pin 26 passing through the top cover 28 is connected with the limiting disc.

[0028] When the sliding cover 20 is needed, the fixing pin 26 is pulled out a certain length, so that the lower end of the fixing pin 26 is separated from the fixing hole 24, and the limiting between the mounting sleeve 19 and the cover 20 is released. When the cover 20 is needed to be closed, the cover 20 is moved to the designated position on the mounting sleeve 19, at this time the through hole 25 and the fixing hole 24 are communicated, under the action of the spring 30, the fixing pin 26 moves to the radial inner side of the mounting sleeve 19, so that the lower end of the fixing pin 26 is inserted into the fixing hole 24, thereby completing the limiting between the mounting sleeve 19 and the cover 20.

[0029] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
