Yarn feeder structure of computerized flat knitting machine

Abstract

This utility model discloses a yarn feeder structure for a computerized flat knitting machine, including a mounting frame. A connecting plate is fixedly mounted at the bottom of the mounting frame, and a yarn feeder body is mounted on one side of the connecting plate. A yarn feeding hole is opened at the bottom end of the yarn feeder body. Correction mechanisms are provided on both sides of the yarn feeder body, and each correction mechanism includes a fixed plate, a fixed rod, a fixed ring, a guide tube, and a U-shaped plate. Fixed plates are slidably connected to both sides of the connecting plate, and a U-shaped plate is fixedly mounted on the side of the two fixed plates that are far apart from each other. Through the correction mechanism, the limiting groove, the limiting block, and the return spring, when the guide tube moves, the fixed plate moves, causing the limiting block to move within the limiting groove. This stretches or compresses the return spring, generating potential energy, which causes the limiting block to perform a reset action. This provides appropriate buffering during the movement of the guide tube, thereby stabilizing the yarn guide.

[0002] The yarn feeder structure of a computerized flat knitting machine is a key component that affects knitting efficiency and product quality. Its design must take into account the stability of yarn feeding, the flexibility of movement, and the needs of multi-color knitting.

[0003] Currently, the yarn feeder guides the yarn through the guide tube on its side wall as it moves. However, the yarn will generate tension as it moves and will run along the guide tube, which may cause friction and wear on the yarn, thus reducing the quality of the subsequent fabric. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a yarn feeder structure for a computerized flat knitting machine to solve the problems mentioned in the background art.

[0006] Both sides of the yarn feeder body are provided with a correction mechanism, and the correction mechanism includes a fixed plate, a fixed rod, a fixed ring, a guide tube and a U-shaped plate. The two sides of the connecting plate are slidably connected with fixed plates. The two fixed plates are fixedly installed with U-shaped plates on the side away from each other. The two U-shaped plates are rotatably connected with fixed rods on both sides of their inner walls. The four fixed rods are hinged with fixed rings at the ends that are close to each other. The inner walls of the two fixed rings are installed with guide tubes.

[0007] In one example, limit grooves are provided on both sides of the connecting plate, and limit blocks that are fixed to the fixing plate are slidably connected to the inner walls of the two limit grooves.

[0008] In one example, a return spring is fixedly installed on one side of each of the two limiting blocks, and the other end of each of the two return springs is fixedly connected to the limiting groove.

[0009] In one example, a miniature cylinder is fixedly mounted on the top of the inner wall of the mounting bracket, and the output shaft of the miniature cylinder is fixedly mounted with a movable rod that is inserted and connected to the mounting bracket.

[0010] In one example, the end of the movable rod located outside the mounting bracket is fixedly connected to the connecting plate.

[0011] In one example, two screws are threadedly connected to one side of the yarn nozzle body, and both screws are threadedly connected to the connecting plate.

[0012] The yarn feeder structure of the computerized flat knitting machine proposed in this utility model can bring the following beneficial effects:

[0013] 1. The yarn feeder structure of this computerized flat knitting machine, through the correction mechanism, limiting groove, limiting block and return spring, when the guide bobbin moves, the fixed plate can move and drive the limiting block to move in the limiting groove, and will stretch or compress the return spring to generate potential energy, and under the action of its potential energy, the limiting block will perform a reset action, and can provide appropriate buffering when the guide bobbin moves, thereby stabilizing the yarn guide.

[0019] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0020] like Figures 1-3 As shown, the embodiment of this utility model proposes a yarn feeder structure for a computerized flat knitting machine, including a mounting frame 1, a connecting plate 4 fixedly provided at the bottom of the mounting frame 1, a yarn feeder body 5 installed on one side of the connecting plate 4, and a yarn feeding hole 6 opened at the bottom end of the yarn feeder body 5.

[0021] Both sides of the yarn feeder body 5 are provided with a correction mechanism, and the correction mechanism includes a fixing plate 11, a fixing rod 12, a fixing ring 13, a guide tube 14 and a U-shaped plate 15. The two sides of the connecting plate 4 are slidably connected with the fixing plate 11. The U-shaped plate 15 is fixedly installed on the side of the two fixing plates 11 that is far apart from each other. The two sides of the inner wall of the two U-shaped plates 15 are rotatably connected with the fixing rod 12. The ends of the four fixing rods 12 that are close to each other are hinged with the fixing ring 13. The inner wall of the two fixing rings 13 is installed with the guide tube 14.

[0022] Specifically, limit grooves 8 are provided on both sides of the connecting plate 4, and limit blocks 9 fixed to the fixing plate 11 are slidably connected to the inner walls of the two limit grooves 8. The limit blocks 9 are installed through the limit grooves 8, and the limit blocks 9 are fixed to the reset spring 10.

[0023] Specifically, a reset spring 10 is fixedly installed on one side of each of the two limit blocks 9, and the other end of each of the two reset springs 10 is fixedly connected to the limit groove 8. The reset spring 10 performs a reset movement, which drives the limit block 9 to perform a reset movement, and can provide appropriate buffering for the moving fixed plate 11.

[0024] Specifically, a miniature cylinder 2 is fixedly installed on the top of the inner wall of the mounting frame 1. The output shaft of the miniature cylinder 2 is fixedly installed with a movable rod 3 that is inserted and connected to the mounting frame 1. The movable rod 3 is driven to move by the miniature cylinder 2, and the movable rod 3 drives the connecting plate 4 to move.

[0025] Specifically, the end of the movable rod 3 located outside the mounting bracket 1 is fixedly connected to the connecting plate 4, and the yarn nozzle body 5 is fixed through the connecting plate 4.

[0026] Specifically, two screws 7 are threadedly connected to one side of the nozzle body 5, and both screws 7 are threadedly connected to the connecting plate 4, thereby fixing the nozzle body 5 and the connecting plate 4 together through the screws 7.

[0027] Working principle: During operation, the yarn passes through the guide tube 14 and then through the yarn feeding hole 6. When the yarn moves, tension may be generated, which will pull the guide tube 14 to move. At this time, the fixed ring 13 will drive the fixed rod 12 to move, which will drive the U-shaped plate 15 to move, and drive the fixed plate 11 to move. It can also drive the limiting block 9 to move in the limiting groove 8, which will stretch or compress the return spring 10, so that the return spring 10 generates potential energy and performs a reset action under the action of its potential energy. It can also provide appropriate buffering when the guide tube 14 moves and stabilize the yarn. When it is necessary to adjust the height of the yarn feeding hole 6 on the yarn nozzle body 5, the micro cylinder 2 is activated and the connecting plate 4 is raised and lowered through the movable rod 3, which can also drive the yarn nozzle body 5 to raise and lower, thereby adjusting the height of the yarn feeding hole 6 and improving its working efficiency.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
