Detailed implementation manner

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1-4 shown, the present invention provides a yarn feeder for a knitting flat knitting machine, including a mounting mechanism 1, and an adjusting mechanism 2 is fixedly connected to the top of the mounting mechanism 1;

[0026] The adjusting mechanism 2 includes a fixing plate 201. On one side of the outer wall of the fixing plate 201, two first mounting holes 202 are provided. On the inner walls of the two first mounting holes 202, first bearings 203 are fixedly inserted. Inside the two first bearings 203, yarn guide rollers 204 are fixedly inserted. On one side of the outer wall of the fixing plate 201, a second mounting hole 205 is provided. On the inner wall of the second mounting hole 205, a second bearing 206 is fixedly inserted. Inside the second bearing 206, a rotating shaft 207 is fixedly inserted. A rotating rod 208 is fixedly sleeved on the outer surface of the rotating shaft 207. On one side of the outer wall of the rotating rod 208, a first fixing rod 209 is fixedly installed. An electric push rod 210 is movably sleeved on the outer surface of the first fixing rod 209. A second fixing rod 211 is movably inserted into the electric push rod 210, and one side of the outer wall of the fixing plate 201 is fixedly connected to one side of the outer wall of the second fixing rod 211. On one side of the outer wall of the rotating rod 208, a third mounting hole 212 is provided. On the inner wall of the third mounting hole 212, a third bearing 213 is fixedly inserted. Inside the third bearing 213, an adjusting roller 214 is fixedly inserted. On one side of the outer wall of the fixing plate 201, an arc-shaped groove 215 is provided, and the outer surface of the adjusting roller 214 is movably inserted into the arc-shaped groove 215.

[0027] The effect achieved by the entire Example 1 is that the yarn first passes over the top of one yarn guide roller 204, then enters the bottom of the adjusting roller 214, and then enters the top of the other yarn guide roller 204. This layout design is mainly to control the path of the yarn to ensure that the yarn maintains a stable tension and direction during transmission. In this way, the yarn is effectively guided and tensioned, avoiding slack or excessive tightness. When the yarn tension is insufficient, the staff first activates the electric push rod 210. The telescopic end of the electric push rod 210 will drive the rotating rod 208 to rotate clockwise around the rotating shaft 207. This action will further cause the adjusting roller 214 to move downward along the trajectory of the arc-shaped groove 215. As the adjusting roller 214 descends, the relative distance between the adjusting roller 214 and the two yarn guide rollers 204 will increase, thereby increasing the pressure on the yarn and improving the yarn tension. This process will continue until the yarn obtains sufficient tension to ensure the stability and product quality during knitting or textile processes. In this way, the system can automatically adjust the yarn tension, reduce production problems caused by uneven tension, and improve production efficiency and product quality.

[0028] Example 2, as Figures 2-4As shown, the installation mechanism 1 includes a bottom plate 101. A clamping groove 102 is formed at the top of the bottom plate 101. A clamping block 103 is movably inserted into the inner wall of the clamping groove 102. A yarn feeder body 104 is fixedly connected to the top of the clamping block 103. Two limiting grooves 105 are formed in the outer wall of the clamping block 103. Limiting blocks 106 are movably inserted into the inner walls of the two limiting grooves 105. A pulling block 107 is fixedly connected to one side of the outer wall of each of the two limiting blocks 106. A reset spring 108 is fixedly connected to one side of the outer wall of each of the two pulling blocks 107. The top of the bottom plate 101 is fixedly connected to the bottom of the fixing plate 201.

[0029] The effect achieved by the entire embodiment 2 is that when the yarn feeder body 104 needs to be disassembled for maintenance, cleaning or replacement, first pull the two pulling blocks 107. These two pulling blocks 107 will respectively drive the two limiting blocks 106 to move outward. During this process, the movement of the two pulling blocks 107 will stretch the two reset springs 108 and generate elastic potential energy. Once the two limiting blocks 106 completely move out of the two limiting grooves 105, the yarn feeder body 104 can be easily removed from the bottom plate 101, facilitating subsequent operations. When the yarn feeder body 104 needs to be reinstalled, just align the clamping block 103 at the bottom of the yarn feeder body 104 and insert it into the clamping groove 102. Subsequently, utilize the elastic potential energy released by the two reset springs 108 to push the two limiting blocks 106 to move inward respectively until they smoothly enter the limiting grooves 105 on both sides of the bottom plate 101. This process realizes the stable connection between the yarn feeder body 104 and the bottom plate 101, ensuring the stability and reliability of the yarn feeder during operation.

[0030] Working principle: When using the yarn feeder, the yarn first passes through the yarn hole at the top of the yarn feeder body 104, and then sequentially passes over the top of a yarn guide roller 204, under the bottom of the adjusting roller 214, and over the top of another yarn guide roller 204. In this way, the yarn can be guided to travel along a predetermined path while ensuring that the yarn maintains appropriate tension and stability during transmission. Through the coordinated action of the adjusting roller 214 and the two yarn guide rollers 204, the tension of the yarn can be effectively controlled to prevent it from being too loose or too tight. When the yarn tension is insufficient, the electric push rod 210 is first activated, and its telescopic end drives the rotating rod 208 to rotate clockwise around the rotating shaft 207. This action causes the adjusting roller 214 to move downward along the track of the arc-shaped groove 215, thereby increasing the relative distance between the adjusting roller 214 and the two yarn guide rollers 204. This adjustment enhances the pressing effect of the adjusting roller 214 on the yarn, thereby increasing the tension of the yarn until it reaches a stable state, ensuring the smooth progress of the knitting or textile process and product quality. On the contrary, when the yarn tension is too high, by activating the electric push rod 210 to contract its telescopic end, the adjusting roller 214 is driven to move upward along the arc-shaped groove 215, reducing the vertical distance from the yarn guide roller 204, thereby reducing the pressing force on the yarn and achieving the purpose of adjusting the tension. When the yarn feeder body 104 needs to be disassembled for maintenance, cleaning or replacement, the operator first pulls two pulling blocks 107. These two pulling blocks 107 drive two limit blocks 106 to move outward through mechanical connection, causing them to disengage from the limit grooves 105 on the bottom plate 101. During this process, two reset springs 108 are stretched and store elastic potential energy. Once the limit blocks 106 are completely removed from the limit grooves 105, the yarn feeder body 104 can be easily removed from the bottom plate 101. When reinstalling the yarn feeder body 104, the two reset springs 108 use the elastic potential energy they store to automatically push the two limit blocks 106 to move inward until the two limit blocks 106 are reinserted into the two limit grooves 105, realizing the firm connection between the yarn feeder body 104 and the bottom plate 101.

[0031] The above is only the preferred embodiment of the present invention and is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
