Technical Field

[0001] This utility model relates to the field of yarn feeder technology, and more specifically, to an anti-tangling device for a computerized flat knitting machine yarn feeder. Background Technology

[0002] The yarn feeder is a key component in textile machinery used to control the speed and tension of yarn feeding. It is mainly used in equipment such as knitting machines to ensure that the yarn is fed evenly into the knitting needles and maintain constant tension, thereby improving the quality and efficiency of knitted fabrics.

[0003] However, in the actual process of wool yarn conveying, if the wool yarn is too loose, it is easy for the wool yarn to get tangled on the yarn conveying roller, which will prevent the wool yarn from being conveyed normally. At the same time, it is necessary to stop the operation of the entire textile machinery to clean the wool yarn tangled on the yarn conveying roller, which brings unnecessary trouble to the staff and affects the overall work efficiency of the machinery.

[0004] Therefore, an anti-tangling device for the yarn feeder of a computerized flat knitting machine is proposed to address the above problems. Utility Model Content

[0007] Preferably, one end of the connecting shaft has a threaded hole, and a bolt for limiting and fixing the guide conveyor roller is threaded into the threaded hole at one end of the connecting shaft.

[0008] Preferably, the limiting component includes an external gear shaft, a first connecting ring, and an internal gear groove. An external gear shaft is fixedly provided at one end of the connecting shaft cylinder, and a first connecting ring is sleeved on the outer side of the external gear shaft. An internal gear groove is provided at the central axis position of the first connecting ring, and the external gear shaft is engaged with the internal gear groove provided at the central axis position of the first connecting ring.

[0009] Preferably, rubber pads are connected to the surfaces of the fixed adsorption block and the movable adsorption block that are in contact with each other, and the surfaces of the rubber pads are provided with rough textures to increase the friction between the rubber pads and the wool yarn.

[0010] Preferably, the connecting card holder has an engaging notch, the top wall of the engaging notch is connected to an elastic clamping piece, and the bottom wall of the engaging notch is fixedly provided with a rubber gasket.

[0011] Preferably, the diameter of the connecting shaft cylinder and the external gear shaft are the same, and both the connecting shaft cylinder and the external gear shaft can pass through the connecting slot hole opened on the surface of the connecting card seat.

[0023] 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.

[0024] Example 1

[0025] As attached Figures 1 to 8 The anti-winding device for the yarn feeder of a computer flat knitting machine shown includes a connecting bracket 1 with a connecting slot 4. A connecting shaft cylinder 11 is rotatably connected to the connecting slot 4. A first connecting arm 5 is fixedly mounted on the outer side of one end of the connecting shaft cylinder 11. A movable suction block 6 is connected to one end of the first connecting arm 5. An installation port 10 is provided on the movable suction block 6, and a first magnetic suction block 7 is provided inside the installation port 10. A fixed suction block 8 is fixedly mounted on the side wall of the connecting bracket 1, and an installation port is provided on the fixed suction block 8. 10. A second magnetic adsorption block 9 is provided inside the mounting port 10. The other end of the connecting shaft cylinder 11 is connected to a second connecting arm 15 through a limiting component. The end of the second connecting arm 15 away from the connecting shaft cylinder 11 is connected to a second connecting ring 16. A connecting shaft 17 is rotatably connected to the second connecting ring 16. A guide conveying roller 18 is sleeved on the outside of the connecting shaft 17. A threaded hole is opened at one end of the connecting shaft 17. A bolt for limiting and fixing the guide conveying roller 18 is threaded into the threaded hole at one end of the connecting shaft 17.

[0026] Specifically: When the conveyed wool yarn is relatively loose, the first magnetic adsorption block 7 and the second magnetic adsorption block 9 attract each other, thereby causing the movable adsorption block 6 to come into contact with the fixed adsorption block 8. The movable adsorption block 6 and the fixed adsorption block 8, which come into contact with each other, clamp and fix the wool yarn passing between them, preventing the loose wool yarn from continuing to fall and then winding onto the yarn conveying roller. Simultaneously, when the wool yarn is at its normal tension, it will squeeze the guide conveying roller 18, and the squeezed guide conveying roller 18 will... The external gear shaft 12 rotates around the pivot point. Simultaneously, through the engagement connection between the external gear shaft 12 and the internal gear groove 14 opened on the central axis of the first connecting ring 13, the external gear shaft 12, the connecting shaft cylinder 11, and the first connecting arm 5 rotate. Then, the rotating first connecting arm 5 drives the movable adsorption block 6 away from the fixed adsorption block 8. At this time, the fixed adsorption block 8 and the movable adsorption block 6 open up, and the guide conveying roller 18 set on the second connecting ring 16 supports the wool yarn, ensuring the normal conveying of the wool yarn and improving the practicality of the device.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details:

[0029] In a preferred embodiment, the limiting component includes an external gear shaft 12, a first connecting ring 13, and an internal gear groove 14. The external gear shaft 12 is fixedly installed at one end of the connecting shaft cylinder 11, and the first connecting ring 13 is sleeved on the outside of the external gear shaft 12. Then, an internal gear groove 14 is opened at the central axis position of the first connecting ring 13, and the external gear shaft 12 is engaged in the internal gear groove 14 opened at the central axis position of the first connecting ring 13. When the guide conveying roller 18 is squeezed by the wool yarn, the second connecting arm 15 will rotate. At this time, through the engagement connection between the external gear shaft 12 and the internal gear groove 14 opened at the central axis of the first connecting ring 13, the external gear shaft 12, the connecting shaft cylinder 11, and the first connecting arm 5 are driven to rotate. Then, the rotating first connecting arm 5 drives the movable adsorption block 6 away from the fixed adsorption block 8. At this time, the fixed adsorption block 8 and the movable adsorption block 6 open, releasing the clamping and fixing of the wool yarn, and the wool yarn can be conveyed normally.

[0030] In a preferred embodiment, rubber pads are connected to both the fixed adsorption block 8 and the movable adsorption block 6 on the side surfaces that are in contact with each other. The rubber pads are provided with rough textures. The rough textures can increase the friction between the rubber pads and the wool yarn, making it easier to clamp and fix the wool yarn stably.

[0031] In a preferred embodiment, a locking notch 2 is provided on the connecting card seat 1, and an elastic clamping piece 3 is connected and provided on the top wall of the inner wall of the locking notch 2. A rubber pad is fixedly provided on the bottom wall of the inner wall of the locking notch 2. In use, the entire device can be clamped and fixed on the connecting rod at the wool yarn input end by the cooperation of the locking notch 2 and the elastic clamping piece 3.

[0032] The working process of this utility model is as follows: First, as follows... Figure 8 As shown, the wool yarn passes through the movable adsorption block 6 and the fixed adsorption block 8, then winds around the two yarn conveying rollers, then passes through the outer wall of the guide conveying roller 18, and finally passes out through the output end hole on the wool yarn connecting rod. In use, the connecting card seat 1 clamps and fixes the entire device on the connecting rod at the wool yarn input end by engaging the notch 2 and the elastic clamping piece 3.

[0033] When the conveyed wool yarn is relatively loose, the guide conveyor roller 18 is not compressed by the wool yarn. At this time, the first magnetic adsorption block 7 and the second magnetic adsorption block 9 attract each other, thereby causing the movable adsorption block 6 to come into contact with the fixed adsorption block 8. The movable adsorption block 6 and the fixed adsorption block 8, which come into contact with each other, clamp and fix the wool yarn passing between the movable adsorption block 6 and the fixed adsorption block 8, preventing the loose wool yarn from continuing to fall and then winding onto the yarn conveyor roller. At the same time, when the wool yarn is at its normal tension, the wool yarn will squeeze the guide conveyor roller 18, and then the guide conveyor roller 18, which is squeezed, will have its outer toothed shaft... The device rotates around pivot point 12. Simultaneously, through the engagement connection between the external gear shaft 12 and the internal gear groove 14 opened on the central axis of the first connecting ring 13, the external gear shaft 12, the connecting shaft cylinder 11, and the first connecting arm 5 rotate. Then, the rotating first connecting arm 5 drives the movable adsorption block 6 away from the fixed adsorption block 8. At this time, the fixed adsorption block 8 and the movable adsorption block 6 open up, and the guide conveying roller 18 set on the second connecting ring 16 supports the wool yarn, ensuring the normal conveying of the wool yarn and improving the practicality of the device. The above is the working principle of the anti-winding device of the computer flat knitting machine yarn feeder.
