[0002] Polyester fiber is a high-quality synthetic fiber. The sutures made from it are strong, ranking second only to nylon thread among all types of sutures. Moreover, its strength does not decrease when wet. Its abrasion resistance is second only to nylon, and its moisture regain is low. It has good high-temperature resistance, low-temperature resistance, light resistance and water resistance. Therefore, polyester thread is a very widely used variety. In many occasions, it has replaced cotton sewing thread. Polyester thread has a wide range of uses. It can be used for sewing clothing made of cotton fabrics, chemical fiber fabrics and blended fabrics, as well as for sewing knitted outerwear. Special polyester thread is also an excellent thread for the footwear, hats and leather industries. A twisting device is required when twisting the sewing threads.

[0026] Through the positioning assembly 7, the positioning pin 8 slides as a whole along the guide rod 9, and the positioning pin 8 pushes the ejection spring 10 and drives the ejection spring 10 to compress as a whole, so that the positioning pin 8 is retracted as a whole, the winding wheel 5 for winding the wire is placed on the rotating frame 4, and the rotating shaft on the rotating frame 4 is directly installed in the clamping groove 6, the positioning pin 8 is loosened, and the rotating shaft is auxiliary positioned under the action of the compressed ejection spring 10, so that the stable clamping installation of the winding wheel 5 can be achieved during operation.

[0027] Reference Figure 1 and Figure 3As shown, a fixing sleeve 31 is sleeved and fixed at the middle section of the cross bar 3, and a U-shaped clamping frame 11 is symmetrically protruded on the fixing sleeve 31. A through groove is provided on the clamping frame 11, and cavities are equidistantly provided in the through groove. A winding assembly 12 for auxiliary wire winding is installed in the cavity. There are a plurality of winding assemblies 12, and the plurality of winding assemblies 12 are staggered up and down.

[0028] Through the cooperation between the clamping frame 11 arranged on the fixed sleeve 31 and the winding component 12 thereon, the wires are twisted as a whole during the rotation of the rotating disk 2 and the action of the winding motor pulling the wires. During the winding process, the push-out spring 16 installed on the sliding rod 15 can ensure that the wires have a certain tension during the winding process, thereby ensuring that the wires will not become loose during the subsequent twisting process, and ensuring that the twisted wires will not have quality problems due to looseness.

[0029] Reference Figure 1 and Figure 4 As shown, a winding assembly 19 for auxiliary wire winding is installed at one end of the top of the mounting base 1 away from the rotating disk 2, a receiving rod 18 is arranged between the receiving disk 17 and the winding assembly 19, the bottom of the receiving rod 18 is fixed at the top of the mounting base 1, and a threading hole is opened on the receiving rod 18, and the winding assembly 19 includes a U-shaped receiving frame 20, and a winding roller 21 is rotatably arranged on the receiving frame 20, and an extension rod is horizontally fixed on the outer side of the winding roller 21, and a reciprocating screw rod 22 is rotatably arranged on the two extension rods, and a slider 24 is sleeved and installed on the reciprocating screw rod 22, and the reciprocating screw rod 22 is threadedly matched with the slider 24, and a wire hole 241 for the wire to pass through is opened on the slider 24, and an adjusting motor 23 for driving the reciprocating screw rod 22 to rotate is installed on one extension rod.

[0030] Through the winding assembly 19, the winding motor and the adjusting motor 23, the winding motor drives the twisted wire to be wound, and the adjusting motor 23 drives the reciprocating screw rod 22 to rotate. The reciprocating screw rod 22 and the slider 24 are threadedly matched, so that the slider 24 moves as a whole, and then the position of the wire is changed, thereby ensuring that the wire can move back and forth laterally during the winding process, and can stably wind the wire and install it on the winding roller 21, and try to avoid the wire being wound in one place after production, affecting the stable winding of the subsequent wire.

[0031] A guide rod 25 is horizontally fixed on the two extending rods, and the guide rod 25 is installed on the slider 24.

[0035] Start the servo motor, the winding motor and the adjusting motor 23. The winding motor drives the twisted wire to be wound. The rotating disk 2 driven by the servo motor rotates as a whole. During the rotation of the rotating disk 2 and the wire pulled by the winding motor, the wire is twisted as a whole. During the winding process, the ejection spring 16 installed on the sliding rod 15 can ensure that the wire has a certain tension during the winding process, thereby ensuring that the wire will not become loose during the subsequent twisting process.

[0036] During the wire winding process, the adjusting motor 23 is started, and the adjusting motor 23 drives the reciprocating screw 22 to rotate. The reciprocating screw 22 and the slider 24 are threadedly matched, so that the slider 24 moves as a whole, and then the position of the wire is changed, thereby ensuring that the wire can move laterally back and forth during the winding process, and the wire can be stably wound and installed on the winding roller 21.
