Description

Technical Field

[0001] This utility model relates to the field of polyester sewing thread technology, and in particular to a polyester thread twisting device disc. Background Technology

[0002] Polyester fiber is a high-quality synthetic fiber. Sewing thread made from polyester has high strength, second only to nylon among various types of sewing thread, and its strength does not decrease when wet. Its shrinkage rate is very low, less than 1% after proper setting, ensuring that the stitches remain flat, neat, and wrinkle-free. Its abrasion resistance is second only to nylon. It has low moisture regain and good resistance to high and low temperatures, light, and water.

[0003] For example, the authorization announcement number "CN210048905U" describes a polyester thread stranding device. Although it uses a motor, rotating rod, and stranding roller, the motor, after normal operation, drives the rotating rod to rotate, which in turn drives the stranding roller to rotate, thus achieving automatic stranding of the polyester thread, there are several drawbacks. The varying height of the polyester roller at the exit point means that the guide tube's inlet end face is not always parallel to the polyester thread, causing scratches on the thread. Similarly, the varying height of the stranding roller during stranding also results in the guide tube's outlet end face not always being parallel to the polyester thread, leading to scratches. This stranding device reduces the efficiency of the stranding process. Utility Model Content

The polyester thread passes through the upper end of the third transmission wheel, then the lower end of the second transmission wheel, then the upper end of the first transmission wheel, and finally through a guide tube. Multiple polyester threads are stranded by the stranding roller. Because the multiple first transmission wheels correspond one-to-one with the multiple guide tubes and are height-matched, the inlet end face of the guide tube remains parallel to the polyester thread, preventing scratching. The lifting device, when the polyester thread forms a certain angle with the outlet end face of the guide tube, activates the first cylinder, extending the first telescopic rod and driving the stranding roller upwards, ensuring the outlet end face of the guide tube remains parallel to the polyester thread, preventing scratching. This stranding device improves the efficiency of stranding. Attached Figure Description
