[0002] Winding, as the final step in spinning and the first step in weaving, plays a crucial "bridge" role, thus holding an important position in the textile industry. The winding machine is a commonly used piece of equipment for winding.

[0003] The winding drum is a crucial component of a winding machine, rotating to guide the yarn onto the yarn bobbin. Existing winding drums, as shown in the applicant's earlier utility model patent application No. 201920065297.8, tend to accumulate a large amount of yarn lint inside after prolonged use. When cleaning the lint is necessary, workers must manually disassemble the winding drum, clean it, and then reassemble it. This process is not only inefficient but also significantly increases the labor intensity for workers.

[0004] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative pneumatic trough for a winding machine to overcome the defects in the prior art. [Utility Model Content]

Detailed Implementation Methods

[0017] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 4 As shown, this utility model is a pneumatic grooved cylinder for a winding machine, which is assembled from several parts such as a cylinder body 1, a cylinder rod 2, a return spring 3, a bushing 4, a first grooved cylinder seat 5, a winding blade 6, a second grooved cylinder seat 7, and a grooved cylinder synchronous pulley 8.

[0018] The cylinder body 1 is fixed to the winding machine, therefore, the cylinder body 1 is fixedly installed. An air inlet 11 is installed at one end of the cylinder body 1.

[0019] The cylinder rod 2 is located in the center of the entire pneumatic cylinder, with one end inserted into the cylinder body, forming an air chamber 12 between the cylinder body 1 and the cylinder rod 2. The air inlet 11 is connected to the air chamber 12, so that high-pressure gas can be introduced into the air chamber 12 through the air inlet 11, thereby driving the cylinder rod 2.

[0020] To prevent the cylinder rod 2 from rotating relative to the cylinder body 1, an anti-rotation pin 13 is provided inside the cylinder body 1. The cylinder rod 2 has a long groove 21 along its radial direction. The anti-rotation pin 13 is housed in the long groove 21 and can move along the long groove 21. This allows the cylinder rod 2 to extend and retract relative to the cylinder body 1, but it will not rotate relative to the cylinder body 1.

[0021] The return spring 3 is sleeved on the cylinder rod 2, connecting the cylinder body 1 and the cylinder rod 2, and can drive the cylinder rod 2. In this embodiment, the return spring 3 is specifically a tension spring. When the high-pressure gas supply is stopped, the tension spring can pull the cylinder rod 2, causing the cylinder rod 2 to return to its original position.

[0022] One end of the cylinder rod 2 is provided with several sealing rings 22, which abut against the inner wall of the cylinder body 1, thereby sealing the air chamber 12 and preventing air leakage.

[0023] Furthermore, the bushing 4 is supported on the cylinder body 1 by a pair of bearings 41. Due to the presence of the bearings 41, the bushing 4 can rotate relative to the cylinder body 1. The first grooved seat 5 is fixed to one end of the bushing 4 and rotates with the bushing 4.

[0024] The grooved cylinder synchronous pulley 8 is supported on the cylinder rod 2 by another bearing 42, and can rotate relative to the cylinder rod 2. The second grooved cylinder seat 7 is mounted on the grooved cylinder synchronous pulley 8 and rotates with the grooved cylinder synchronous pulley 8.

[0025] A guide sleeve 41 is also installed at one end of the bushing 4. A guide cavity 81 is provided inside the grooved synchronous pulley 8, and the guide sleeve 41 can be inserted into the guide cavity 81. When the cylinder rod 2 extends or retracts, the grooved cylinder is opened or closed through the guide sleeve 41 and the guide cavity 81.

[0026] The winding plates 6 are respectively installed on the first grooved cylinder seat 5 and the second grooved cylinder seat 7, and spliced ​​into a cylindrical shape. A yarn groove 61 is formed between adjacent winding plates 6 to guide the yarn to wind into shape.

[0027] The design principle of the pneumatic winding cylinder of this utility model is as follows: When the winding cylinder has been used for a long time and its interior needs cleaning, high-pressure gas is introduced into the air chamber 12 through the air inlet 11, pushing the cylinder rod 2 to extend. The cylinder rod 2 sequentially pushes the winding cylinder synchronous pulley 8, the second winding cylinder seat 7, and the winding strip 6 on it. At this time, the return spring 3 is in a stretched state, and the winding strip 6 of the second winding cylinder seat 7 and the winding strip 6 of the first winding cylinder seat 5 are relatively separated, thus facilitating the worker to clean the yarn lint and other debris inside the winding strip 6. After cleaning is completed, the high-pressure gas supply is stopped. At this time, the spring return 3 pulls the cylinder rod 2, causing the cylinder rod 2 to return to its original position, thus eliminating the need for manual disassembly of the winding cylinder, greatly improving production efficiency and reducing the labor intensity of workers.

[0028] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
