The mounting cylinder 22 is fixedly mounted on one side of the circular plate 2. Two parallel support rings 25 are fixedly installed on the outer side of the mounting cylinder 22. Each support ring 25 has the same number of mounting holes as the spool 23. Two parallel guide wheels 26 are rotatably installed in each mounting hole to provide support and guidance for the yarn. Multiple parallel support wheels are rotatably installed on the side of the two support rings 25 that are close to each other. The multiple support wheels are all rolledly connected to the inner wall of the housing 1 to ensure the stable rotation of the mounting cylinder 22 and the support rings 25.

A pressure plate 24 is radially fixed on the rotating pin 241. The pressure plate 24 movably abuts against the corresponding spool 23. A torsion spring 242, which is movably sleeved on the outside of the rotating pin 241, is fixedly installed between the pressure plate 24 and the inner wall of one side of the mounting slot. This spring can limit the position of the spool 231 on the spool 23 to prevent it from falling off when it moves with the circular plate 2. A vacuum cleaner 272 is fixedly mounted on one side of the housing 1. The hollow shaft 21 is connected to the air inlet of the vacuum cleaner 272. The sealed rotating connection has multiple conveying pipes 271 fixedly installed on the mounting cylinder 22. Multiple cylinders 27 connected to the corresponding two mounting ports are fixedly installed on the side of the two support rings 25 that are close to each other. The multiple conveying pipes 271 extend into the corresponding cylinders 27. The same circular block is fixedly installed in the hollow shaft 21 at the end of the multiple conveying pipes 271 away from the cylinder 27. The multiple conveying pipes 271 are all in communication with the hollow shaft 21, which can perform dust removal operation on the yarn and prevent the debris adhering to the yarn from entering the knitting fabric manufacturing equipment.

[0030] The yarn guide 4 is fixedly installed inside the housing 1 and is located on the same axis as the hollow shaft 21. Multiple support blocks are fixedly installed on the support ring 25 away from the circular plate 2. An electric cylinder 3 is fixedly installed on the support block. An installation block 31 is fixedly installed on the working end of the electric cylinder 3. Two guide rods 321 are slidably installed on the installation block 31. The same installation seat 32 is fixedly installed on the two guide rods 321. A guide wheel 35 is rotatably installed on the installation seat 32. The same spring 33 is provided between the installation seat 32 and the installation block 31, and the spring 33 is fixedly connected to the installation seat 32, which can adjust the tension of the yarn. A pressure sensor 34 is fixedly installed on the end of the spring 33 away from the installation seat 32, and the pressure sensor 34 is fixedly connected to the installation block 31, which can monitor the tension of the yarn in real time. When the tension needs to be adjusted, it can cooperate with the controller to control the electric cylinder 3 to adjust the position of the guide wheel 35, thereby ensuring that the yarn tension is within a suitable range.

[0031] In this embodiment, in order to facilitate the operation of the pressure plate 24 and the disassembly and replacement of the wire roller 231, a handle is fixedly installed on the side of the pressure plate 24 away from the mounting cylinder 22, and an arc-shaped opening is provided on the top of the housing 1, and the arc-shaped opening corresponds to the plane where the circular plate 2 and the wire roller 231 are located.

[0032] The circuits, electronic components, and modular mechanisms involved (such as servo motors, electric cylinders, yarn guides, and pressure sensors) all employ existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0033] Working principle: In use, first connect the power supply, pull the pressure plate 24 upwards by the handle to put the yarn roller 231 onto the yarn shaft 23, then pass the yarn through the corresponding guide roller 26 and around the corresponding guide roller 35, and then guide it into the yarn guide 4 position. When the servo motor 211 starts, the driving gear 212 drives the driven gear 213 to rotate, thereby making the hollow shaft 21 and the circular plate 2 rotate synchronously. This allows the yarn roller 231 to be adjusted to the required position as needed, and thus, with the cooperation of the yarn guide 4, a rapid yarn adjustment operation can be achieved. When the yarn passes through the guide roller 26, it can provide a lifting effect. The electric cylinder 3 provides support and guidance to prevent abnormal friction. At the same time, the electric cylinder 3 adjusts the position of the guide wheel 35 through the mounting block 31 and guide rod 321 to control the tension of the yarn. The pressure sensor 34 can monitor the yarn tension in real time and adjust the electric cylinder 3 through the controller when needed to maintain the yarn tension within a suitable range. When the yarn passes through the cylinder 27, the vacuum cleaner 272 works and extracts air from the multiple cylinders 27 through the hollow shaft 21 and multiple conveying pipes 271, thereby sucking out dust and other debris adhering to the yarn, thus achieving the effect of yarn dust removal.

[0034] The above provides a detailed description of the automatic yarn-adjusting sportswear knitted fabric manufacturing equipment provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
