[0001] The utility model relates to the technical field of copper wire twisting equipment, in particular to a copper wire twisting device. Background Art

[0002] Stranded copper wire, composed of multiple strands of fine copper wire, offers excellent electrical conductivity and flexibility. Wire stranding is an essential step in copper wire production. This process allows multiple individual copper wires to be twisted together into a larger-diameter conductor, improving the wire's flexibility and bendability while meeting the demands of power and signal transmission in various applications.

[0003] The Chinese utility model patent with authorization number CN115410775A provides a copper wire stranding device, which includes a base, a discharge plate fixedly installed on one side of the top of the base, a positioning plate fixedly installed on the top of the base, a guide seat fixedly installed on one side of the top of the positioning plate, a guide hole is opened on the guide seat, and a twisting seat is fixedly installed on the other side of the top of the positioning plate. Through the setting of the transmission mechanism, the twisting part and the cutting part are coordinated, so that the winding is completed, the twisting is stopped and the copper stranded wire is cut at the same time. At this time, the motor stops, and the mounting seat is moved to replace the winding roller. When the replacement is completed, the motor is started to reverse, so that all components are reset to the initial position. The above steps can then be repeated to perform the copper wire stranding operation. The process is simple, and each component can run and stop at the same time, simplifying the operation process and steps, and improving the efficiency of copper wire stranding and production.

[0004] However, the copper wire stranding device provided by the above patent has the problem of copper wire loosening during the stranding process, resulting in uneven distribution of the copper strands. Therefore, it is necessary to provide a solution to improve this problem. Utility Model Content

The gaps between the multiple wire pressing rollers are smaller than the sum of the outer diameters of the multiple copper wires, and are used to press the multiple copper wires.

[0017] By adopting the above technical solution, the twisted multiple copper wires can be pressed together through the gaps between the wire pressing rollers, thereby reducing the gaps between the copper wires.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The words "including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0024] An embodiment of the present utility model provides a copper wire stranding device, comprising a base and a stranding module fixed on the base, the stranding module comprising a pay-off assembly 1 and a tension assembly 2 fixedly connected to the pay-off assembly 1, the pay-off assembly 1 being used to drive the tension assembly 2 to rotate, the tension assembly 2 comprising a guide rod 22, a reset member 23, and an assembly 21, the assembly 21 being fixedly connected to the pay-off assembly 1, the multiple guide rods 22 being plugged into the assembly 21, and a wire entry hole being provided on the guide rod 22, the outer end of the guide rod 22 being sleeved with the reset member 23, and the reset member 23 being in elastic contact with the guide rod 22 and the assembly 21.

[0025] See also Figure 1 Figure 2, multiple strands of copper wire pass through the wire entry hole on the guide rod 22, and the tension assembly 2 is driven to rotate by the wire pay-off assembly 1, driving the guide rod 22 to twist the multiple strands of copper wire. During the twisting process of the copper wire, the copper wire will become loose, resulting in uneven twisting of the copper wire. The reset member 23 in elastic contact with the guide rod 22 can drive the guide rod 22 to move toward the outside of the assembly 21, and then the copper wire in the wire entry hole is stretched and tightened. The utility model can tighten the twisted copper wire and improve the twisting effect of the copper wire. Specifically, the reset member 23 is a return spring, and the reset member 23 is always in a compressed state during the twisting process.

[0026] In some embodiments, an elastic pad 221 is provided in the wire entry hole on the guide rod 22 to protect the copper wire from being worn.

[0027] In fact, during the stranding process, the copper wire passes through the wire entry hole, and the elastic pad 221 in the wire entry hole protects the copper wire from wear and tear, thereby preventing the copper wire from being worn and reducing product quality.

[0028] In some embodiments, the pay-off assembly 1 includes a fixed seat 11, a pay-off drum 14, a pay-off roller 13, a driving member 12, and a driving rod 15. The pay-off drum 14 is fixedly connected to multiple pay-off rollers 13, the driving member 12 is fixed on the fixed seat 11, and the driving member 12 is fixedly connected to the pay-off drum 14 and the tension assembly 2 through the driving rod 15.

[0029] In practice, the driver 12 is fixed to the fixed base 11 and is used to drive the pay-off drum 14 and the assembly 21, which are fixedly connected to the drive rod 15, to rotate, thereby twisting the multiple strands of copper wire. The pay-off roller 13 on the pay-off drum 14 facilitates the continuous twisting of the copper wire. In addition, the driver 12 twists the multiple strands of copper wire by synchronously driving the pay-off drum 14 and the tension assembly 2, which are fixedly connected to the drive rod 15. Specifically, the driver 12 is a motor 421, and the motor 421 can adjust the speed to adjust the copper wire twisting efficiency.

[0030] In some embodiments, the pay-off roller 13 includes a roller and a fixing member, and the fixing member is detachably connected to the roller.

[0031] In fact, after the copper wires on the roller are twisted, the fixing piece can be disassembled and a new copper wire can be connected to the roller, so that the device can continue to work. Specifically, the fixing piece and the roller are matched through threads.

[0032] In some embodiments, the crimping seat 31 on the base is provided with a crimping hole 311 , and the crimping hole 311 is located at the center of the stranded wire and is used to merge multiple strands of copper wire.

[0033] In fact, during the twisting process, the multiple copper wires are converged in the wire pressing hole 311, thereby improving the twisting effect of the multiple copper wires and having a guiding effect on the copper wires.

[0034] In some embodiments, multiple wire pressing rollers 32 are located on the top surface of the wire pressing seat 31, and the multiple wire pressing rollers 32 are distributed on both sides of the wire pressing hole 311. The gap between the multiple wire pressing rollers 32 is smaller than the sum of the outer diameters of the multiple copper wires, and are used to press the multiple copper wires.

[0035] In fact, there will be some gaps between the twisted copper wires. The wire pressing roller 32 can be used to press the multiple copper wires to reduce the gaps between the copper wires, thereby improving the use effect of the product. The unevenly twisted copper wires can also be pressed to ensure the use effect of the copper wires.

[0036] In some embodiments, the wire take-up seat 41 on the base is provided with a wire take-up mechanism 42 for centrally collecting the pressed copper wires.

[0037] In practice, after the copper wires are twisted, the twisted copper wires are collected by the take-up mechanism 42 on the take-up base 41 and further compressed. Specifically, the take-up mechanism 42 includes a take-up drum and a motor 421 that drives the take-up drum. The twisting efficiency of the copper wires can be controlled by adjusting the speed of the motor 421. The speed of the motor 421 and the speed of the driving member 12 need to be compatible with each other to achieve a better twisting effect and avoid copper wire breakage and loosening.

[0038] While the embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations may be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as set forth in the claims. Furthermore, the present invention described herein may have other embodiments and may be implemented or carried out in a variety of ways.
