[0030] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0031] Please see Figures 1-3 A yarn feeder is mainly used on knitting machines. The yarn feeder is mainly used to install yarn bobbins, and the yarn on the yarn bobbins is supplied to the knitting machine. It includes a vertical rod 1, a rotating disk 2 rotatably installed on the vertical rod 1, a locking assembly 3 and a yarn mechanism 4 installed on the rotating disk 2. Multiple rotating disks 2 are installed on the vertical rod 1 to facilitate the installation of multiple yarn bobbins. The inner wall of the rotating disk 2 has an opening, and the inner wall of the opening is slidably connected to a limit block 7. The locking assembly 3 includes a locking box 10 fixedly connected to the rotating disk 2. The rotating disk 2 can rotate on the vertical rod 1. The locking assembly 3 is designed to fix the rotating disk 2 to the vertical rod 1. One side of the outer wall of the locking box 10 has an opening, and the inner wall of the opening is slidably connected to a drive seat 13. The drive seat 13 is fixedly connected to the limit block 7. One side of the outer wall of the drive seat 13 is fixedly connected to a pull rod 14, and one end of the pull rod 14 is fixedly connected to a handle 16.
[0032] In use, a rotating disk 2 is set on the vertical rod 1. When the rotating disk 2 rotates, it drives the yarn mechanism 4 to rotate. The locking component 3 makes it easy to fix the rotating disk 2 on the vertical rod 1, thereby preventing the rotating disk 2 from shaking.
[0033] Reference Figure 4 The inner wall of the locking box 10 is fixedly connected to two symmetrically arranged mounting rods 11, and the outer wall of each mounting rod 11 is fitted with a spring 12. The mounting rods 11 are arranged to facilitate the installation of the spring 12. The drive seat 13 is slidably connected to the outer wall of the two mounting rods 11. The mounting rods 11 are arranged to limit the sliding trajectory of the drive seat 13. The two mounting rods 11 in the locking box 10 facilitate the installation of the spring 12, and the spring 12 directly drives the drive seat 13 to extend.
[0034] Reference Figure 2 and Figure 3 A limiting groove 8 is provided on the outer wall of the vertical rod 1. A limiting block 7 is inserted into the inner wall of the limiting groove 8. The rotation of the rotating disk 2 can be restricted by the limiting block 7 being inserted into the limiting groove 8. When the limiting block 7 is inserted into the limiting groove 8, the rotating disk 2 can be fixed on the vertical rod 1 to prevent the rotating disk 2 from shaking when releasing the yarn.
[0035] Reference Figure 3 A limiting ring 9 is fixedly connected to the outer wall of the vertical rod 1, and the limiting ring 9 is in contact with the rotating disk 2. The limiting ring 9 facilitates the limiting of the rotating disk 2.
[0036] Reference Figure 2 and Figure 3 The yarn mechanism 4 includes a mounting base 5 and an adjusting component 6 rotatably connected to the rotating disk 2. The adjusting component 6 and the mounting base 5 are connected by a drive shaft. The mounting base 5 is designed to facilitate the installation of the yarn bobbin. Rotating the mounting base 5 facilitates the installation of the yarn bobbin. The adjusting component 6 is designed to facilitate the adjustment of the angle of the mounting base 5.
[0037] Reference Figure 5 The adjustment assembly 6 includes an adjustment box 17 fixedly connected to the rotating disk 2, and a gear 18 is rotatably connected to one inner wall of the adjustment box 17. The gear 18 is connected to the drive shaft and the mounting base 5. The gear 18 and the mounting base 5 rotate coaxially. By adjusting the gear 18 in the adjustment box 17 and the mounting base 5 coaxially, the angle of the mounting base 5 can be adjusted. The mounting base 5 facilitates the installation of the yarn bobbin, thereby facilitating the adjustment of the angle of the yarn bobbin.
[0038] Reference Figure 5Two symmetrically arranged fixing rods 19 are fixedly connected to the inner wall of the top of the regulating box 17, and the same limiting rack 20 is slidably connected to the outer wall of the two fixing rods 19. The setting of the fixing rods 19 facilitates the restriction of the sliding trajectory of the limiting rack 20. The limiting rack 20 and the gear 18 mesh with each other. The setting of the fixing rods 19 facilitates the sliding installation of the limiting rack 20. When the limiting rack 20 and the gear 18 mesh, the rotation of the gear 18 can be restricted, thereby ensuring the stability of the mounting base 5.
[0039] Reference Figure 5 The top outer wall of the regulating box 17 has a threaded opening, and a screw 21 is screwed into the inner wall of the threaded opening. One end of the screw 21 is rotatably connected to the limiting rack 20. When the screw 21 rotates, it directly drives the limiting rack 20 to move, thereby facilitating the locking and unlocking of the gear 18. One end of the screw 21 is fixedly connected to a rotating part 22. The rotating part 22 drives the screw 21 to rotate, thereby facilitating the adjustment of the distance between the limiting rack 20 and the gear 18, thereby facilitating the locking or unlocking of the gear 18.
[0040] The implementation principle of this application is as follows: When in use, the yarn bobbin is first installed on the mounting base 5. When adjusting the angle of the yarn bobbin, the rotating part 22 is rotated to drive the screw 21 to rotate. When the screw 21 rotates, it directly drives the limiting rack 20 to move closer to or away from the gear 18. When the limiting rack 20 moves away from the gear 18, the angle of the yarn bobbin can be adjusted. When the angle of the yarn bobbin is adjusted, the limiting rack 20 and the gear 18 can be driven to mesh, thereby ensuring the stability of the yarn bobbin. When replacing the yarn bobbin, the handle 16 is pulled to drive the drive base 13 to move through the pull rod 14. When the drive base 13 moves, it directly drives the limiting block 7 to slide out of the limiting groove 8. At this time, the rotating disk 2 is directly rotated on the vertical rod 1, which facilitates the adjustment of the direction of the yarn mechanism 4 and facilitates the replacement of the yarn bobbin.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
