Description

Technical Field

[0001] This invention relates to the field of yarn clamping technology, specifically to a yarn clamping mechanism for a knitting machine. Background Technology

[0002] Knitting machines utilize needles to form loops from various raw materials and yarns, which are then interlocked to create knitted fabrics. Knitted fabrics are soft, wrinkle-resistant, breathable, and have considerable stretch and elasticity, making them comfortable to wear. Besides clothing and decoration, knitted products are used in industry, agriculture, medical and health fields, and national defense. Knitting is divided into hand knitting and machine knitting. Large circular knitting machines typically have a yarn clamping mechanism, whose main function is to hold the yarn to be knitted. However, existing knitting machine yarn clamping mechanisms have poor stability, and the clamping force is not easily adjustable.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 6 This invention provides a technical solution: a yarn clamping mechanism for a knitting machine, comprising a fixed yarn clamping disc 1, a second connecting shell 23 fixedly connected to one side of the fixed yarn clamping disc 1, an adjusting column 2 slidably connected inside the fixed yarn clamping disc 1 and the second connecting shell 23, a sliding column 3 slidably connected inside the adjusting column 2, a movable yarn clamping disc 10 cooperating with the fixed yarn clamping disc 1 fixedly connected to one end of the sliding column 3, a fixed inner plate 32 fixedly connected inside the adjusting column 2, a pull rod 31 fixedly connected to one end of the sliding column 3, the pull rod 31 slidably connected to the fixed inner plate 32, a first movable plate 6 fixedly connected to the end of the pull rod 31 away from the sliding column 3, the first movable plate 6 slidably connected to the adjusting column 2, a lead screw 20 threadedly connected inside the adjusting column 2, a movable rod 19 slidably connected inside the lead screw 20 cooperating with the first movable plate 6, and so on. The moving rod 19 is movably connected to the second connecting shell 23. The sliding plate 16 is slidably connected inside the second connecting shell 23. One end of the moving rod 19 is rotatably connected to the sliding plate 16. The top of the adjusting column 2 is provided with pointed slots 30 at equal intervals. The second moving plate 27 is slidably connected inside the second connecting shell 23. The bottom of the second moving plate 27 is fixedly connected with a pointed block 29 that cooperates with the pointed slot 30. The top of the second moving plate 27 is rotatably connected with an adjusting bolt 28. The adjusting bolt 28 is threadedly connected to the second connecting shell 23. Two springs 7 are symmetrically provided on one side of the first moving plate 6. One end of the spring 7 is fixedly connected to the second connecting shell 23. The first moving plate 6 compresses the spring 7 and clamps the knitting yarn through the moving clamping plate 10 and the fixed clamping plate 1, thereby adjusting the elasticity of the spring 7.

[0024] The top and bottom of the adjusting column 2 are fixedly connected to the first limiting slider 4. The inner sides of the fixed clamping plate 1 and the second connecting shell 23 are symmetrically opened with two first limiting grooves 5. The first limiting slider 4 is slidably connected to the first limiting groove 5. The first limiting slider 4 and the first limiting groove 5 limit the sliding, thereby enabling the fixed clamping plate 1, the sliding column 3 and the movable clamping plate 10 to rotate synchronously.

[0025] The top and bottom of the sliding column 3 are fixedly connected with the second limiting slider 8, and the inner side of the adjusting column 2 is symmetrically provided with two second limiting grooves 9, and the second limiting slider 8 is slidably connected to the second limiting groove 9.

[0026] Two No. 3 limit sliders 21 are symmetrically fixedly connected to the outer side of the moving rod 19, and two No. 3 limit grooves 22 are symmetrically opened on the inner side of the lead screw 20. The No. 3 limit sliders 21 and the No. 3 limit grooves 22 are slidably connected. When the No. 3 limit sliders 21 rotate, they drive the No. 3 limit grooves 22 and the lead screw 20 to rotate. The lead screw 20 adjusts the position of the adjusting column 2, thereby adjusting the distance between the fixed clamping plate 1 and the moving clamping plate 10.

[0027] The movable rod 19 has two symmetrically arranged fourth-position sliding grooves 34 on its outer side. A worm gear 26 is slidably connected to the outer side of the movable rod 19. Two fourth-position sliding blocks 33 are symmetrically fixedly connected to the inner side of the worm gear 26. The fourth-position sliding blocks 33 are slidably connected to the fourth-position sliding grooves 34. A worm 25 is rotatably connected inside the second connecting shell 23. The worm 25 is meshed with the worm gear 26. When the worm 25 rotates, it drives the fourth-position sliding blocks 33 on the inner side to rotate and adjust the fourth-position sliding grooves 34 through the worm gear 26. The movable rod 19 is rotated through the fourth-position sliding grooves 34. The left and right adjustment extension does not affect the rotation adjustment.

[0028] Among them, the top of the second connecting shell 23 is rotatably connected to the second rotating screw block 24, and one end of the worm 25 is fixedly connected to the second rotating screw block 24. The worm 25 is rotated and adjusted by the second rotating screw block 24.

[0029] Among them, two fixed plates 15 are fixedly connected to one side of the second connecting shell 23, and an adjusting screw 17 is threadedly connected inside the sliding plate 16. The adjusting screw 17 is rotatably connected to the fixed plate 15, and the position of the sliding plate 16 is adjusted when the adjusting screw 17 rotates.

[0030] One of the fixed plates 15 is rotatably connected to a first rotating screw block 18 on one side. One end of the adjusting screw 17 is fixedly connected to the first rotating screw block 18. The first rotating screw block 18 rotates the adjusting screw 17 to adjust the position of the sliding plate 16.

[0031] Among them, a limiting post 11 is fixedly connected to one side of the movable clamping plate 10, and a first connecting shell 12 is slidably connected to the outside of the limiting post 11. Two limiting plates 13 are symmetrically fixedly connected to one side of the limiting post 11. The limiting plates 13 are slidably connected to the first connecting shell 12, and the limiting plates 13 are limited to slide within the first connecting shell 12 to ensure synchronous rotation between the first connecting shell 12 and the limiting post 11.

[0032] Among them, the second connecting shell 23 and the first connecting shell 12 are both fixedly connected to one side of the mounting rod 14, and the clamping mechanism is installed on the equipment by means of the two mounting rods 14.

[0033] Specifically, in use, the worm gear 25 is rotated by the second rotating screw block 24. When the worm gear 25 rotates, it drives the inner fourth limiting slider 33 via the worm wheel 26, which in turn drives the fourth limiting groove 34 to rotate and adjust. The fourth limiting groove 34 then drives the moving rod 19 to rotate. When the moving rod 19 rotates, it drives the outer third limiting slider 21 to rotate. When the third limiting slider 21 rotates, it drives the third limiting groove 22 and the lead screw 20 to rotate. The lead screw 20 adjusts the position of the adjusting column 2, thus fixing the position of the fixed column. The distance between the fixed clamping disc 1 and the movable clamping disc 10 is adjusted by rotating the adjusting screw 17 through the first rotating screw block 18. When the adjusting screw 17 rotates, it pushes the sliding plate 16 and the moving rod 19. The moving rod 19 pushes the first moving plate 6. When the first moving plate 6 pushes, it drives the pull rod 31 and the sliding column 3 to move outward. The first moving plate 6 compresses the spring 7. The knitting yarn is clamped by the movable clamping disc 10 and the fixed clamping disc 1, and the elasticity of the spring 7 is adjusted by pressing.
