[0002] The yarn feeder is one of the important components of a knitting machine, used for feeding yarn. With the development of yarn feeders, there are various types and shapes of yarn feeders.

[0003] For example, a Chinese patent discloses a yarn feeder with an adjustable yarn feeding angle, with application number CN202021549320.X. It includes a mounting plate, a slot, and a yarn feeder body. The mounting plate has a mounting hole at its top and a slot on its lower surface, with a threaded rod connected to the center of the slot. A connecting piece is connected to the bottom of the mounting plate, and a yarn feeding groove is formed above the connecting piece. A limiting piece is fixed to the surface of the connecting piece. The yarn feeder body is located below the mounting plate, and an inlet plate is located below the yarn feeder body. The patent allows the connecting teeth on the top of the yarn feeder body to rotate below the mounting plate by rotating the yarn feeder body, facilitating the adjustment of the yarn feeder body's operating angle. Combined with the use of the threaded rod, the lower part of the threaded rod protrudes between the connecting teeth, facilitating the fixing of the yarn feeder body after angle adjustment.

[0004] However, during the process of feeding yarn through the yarn feeding hole by the yarn guiding device, although direct contact between the yarn and the yarn feeding hole is avoided, reducing yarn wear and breakage, the yarn guiding device will wear out after guiding the yarn for a long time, and burrs will appear on the surface, which will increase the possibility of yarn breakage. Therefore, it needs to be replaced quickly. Utility Model Content

[0015] This utility model proposes a yarn feeder with an adjustable yarn feeding angle;

[0016] By incorporating a quick-change device, when replacing the yarn guide device, the slider is pulled down and slids within the second sliding cavity. One side of the slider contacts the abutment on the side wall of the limiting block, causing the abutment to slide within the groove. This causes the limiting block to slide within the first sliding cavity, compressing the spring on the sleeve. The spring's elasticity then disengages the limiting block from the limiting groove, allowing for quick replacement of the yarn guide device. Similarly, when installing the yarn guide device, the mounting block on the lower surface of the bracket is inserted into the mounting groove, and the slider is released. The spring's rebound energy then engages the limiting block, completing the quick installation of the yarn guide device. This allows for rapid replacement of worn yarn guide devices, preventing yarn breakage risks due to delayed replacement, reducing downtime, and lowering production costs. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1 to 7 This utility model provides a technical solution: a yarn feeder with an adjustable yarn feeding angle;

[0027] Example 1:

[0028] To enable rapid replacement of worn yarn guide devices, a first sliding cavity 16 and a second sliding cavity 17 are formed on the inner surface of the frame 15. A groove 21 is provided between the first sliding cavity 16 and the second sliding cavity 17. A limiting block 19 is provided on the inner surface of the first sliding cavity 16. A sleeve post 18 is fixedly installed at the end of the first sliding cavity 16 away from the limiting block 19. A spring 20 is fitted on the outer surface of the sleeve post 18. The end of the spring 20 away from the sleeve post 18 is elastically connected to the limiting block 19. A stop post 22 is fixedly installed on the side wall of the limiting block 19. A slider 23 is provided on the inner surface of the second sliding cavity 17. The limiting block 19 is slidably installed on the inner surface of the first sliding cavity 16 through the elastic connection of the spring 20. The first sliding cavity 16 and the second sliding cavity 17 are separated by the groove 21. The side wall of the stop post 22 is connected to the side wall of the slider 23. The slider 23 slides on the inner surface of the slide groove 21 under the force of the slider 23. By pulling the slider 23 down, it slides in the second slide cavity 17. One side of the slider 23 contacts the abutment 22 on the side wall of the limiting block 19, thereby causing the abutment 22 on the side wall of the limiting block 19 to slide in the slide groove 21. This causes the limiting block 19 to slide in the first slide cavity 16 and compress the spring 20 on the sleeve column 18. Through the elastic connection of the spring 20, the limiting block 19 is driven to disengage from the limiting groove 12, so that the yarn guide device can be quickly replaced. When installing the yarn guide device, the mounting block 11 on the lower surface of the bracket 10 is inserted into the mounting groove 9, the slider 23 is released, and the rebound energy of the spring 20 drives the limiting block 19 to be inserted into the limiting groove 12, thereby completing the quick installation of the yarn guide device.

[0029] Working principle: In actual use, by pulling down the slider 23 and sliding it in the second sliding cavity 17, one side of the slider 23 contacts the abutment 22 on the side wall of the limiting block 19, thereby driving the abutment 22 on the side wall of the limiting block 19 to slide in the sliding groove 21. This causes the limiting block 19 to slide in the first sliding cavity 16 and compress the spring 20 on the sleeve 18. Through the elastic connection of the spring 20, the limiting block 19 is driven to disengage from the limiting groove 12, thus allowing for quick replacement of the yarn guide device. When installing the yarn guide device, by inserting the mounting block 11 on the lower surface of the bracket 10 into the mounting groove 9 and releasing the slider 23, the rebound energy of the spring 20 drives the limiting block 19 to engage in the limiting groove 12, thereby completing the quick installation of the yarn guide device. This allows for the rapid replacement of worn yarn guide devices, avoiding the risk of yarn breakage due to failure to replace worn yarn guide devices in time, reducing downtime, and lowering production costs.
