Technical Field
[0001] This utility model relates to the field of power cord twisting technology, and in particular to a DC power cord twisting machine. Background Technology
[0002] With the rapid development of the electrification and automation industries, DC power cords are increasingly widely used in various electrical devices. Against this backdrop, the production efficiency and quality requirements for DC power cords are also rising. As a crucial piece of equipment in this industry, the DC power cord twisting machine is responsible for twisting the conductor and insulation material of the power cord together, making it a key device for ensuring the performance and quality of the power cord. To improve production efficiency and ensure product quality, twisting machine technology is constantly evolving, especially in the precision of pressure control during the twisting process, which has become an important direction for improving its performance.
[0003] Existing DC power cord twisting machines generally employ a mechanized structure, using a mechanical drive system and a power transmission system to complete the twisting operation. The core principle is that a motor drives a rotating wheel, which in turn drives the twisting head via a chain or gear to perform the twisting operation. Simultaneously, the twisting machine is typically equipped with a sensor system to monitor the rotational speed of the twisting head and the twisting tension. In these devices, the twisting head usually twists the power cord with constant pressure. During the twisting process, the conductor and insulation material of the power cord form a tight connection through continuous compression and rotation, ensuring the stability and high conductivity of the power cord.
[0004] However, existing DC power cord twisting machines typically use a fixed pressure setting during the twisting process, lacking adaptive pressure guidance, resulting in uneven pressure during twisting. During production, due to differences in power cord specifications, wire hardness, and thickness, a fixed pressure cannot adapt to power cords of different materials and specifications, leading to uneven twisting. This uneven pressure affects the stability of the wire, thus impacting product quality, increasing scrap rates, and reducing production efficiency. Therefore, a new DC power cord twisting machine is proposed to address these issues. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a DC power cord twisting machine, which aims to improve the problem that the lack of adaptive pressure function in the existing technology leads to uneven pressure during the twisting process, resulting in unstable wire and affecting production efficiency and product quality.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A DC power cord twisting machine includes a bracket, a drive shaft fixedly connected to the top of the bracket, a fixed plate fixedly connected to the bottom of the bracket, a motor fixedly connected to the bottom of the fixed plate, a first drive wheel fixedly connected to the output end of the motor, a support ring fixedly connected to the top of the bracket, a second drive wheel rotatably connected to the side wall of the support ring, a synchronous belt rotatably connecting the outer walls of the first drive wheel and the second drive wheel, a connecting column fixedly connected to the side wall of the second drive wheel, a twisting head provided on the side wall of the connecting column, and a guide assembly provided on the top of the bracket.
[0008] The guide assembly includes a support plate, the bottom of which is fixedly connected to the top of the bracket. A sliding column is slidably connected inside the support plate. A nut is fixedly connected to the outer wall of the sliding column. A slotted plate is fixedly connected to one end of the sliding column. A rotating wheel is rotatably connected to the inner wall of the slotted plate. A spring-loaded assembly is provided on the outer wall of the sliding column.
[0009] As a further description of the above technical solution:
[0010] The rebound assembly includes a second spring, one end of which is fixedly connected to the outer wall of the sliding column, and the other end of which is fixedly connected to the side wall of the slot plate.
[0011] As a further description of the above technical solution:
[0012] A hollow column is slidably connected to the inner wall of the twisted thread head, and a button is slidably connected to the inner wall of the hollow column.
[0013] As a further description of the above technical solution:
[0014] One end of the button is fixedly connected to a trapezoidal column, and the outer wall of the trapezoidal column is slidably connected to the inner wall of the hollow column.
[0015] As a further description of the above technical solution:
[0016] The trapezoidal column sidewall is provided with a retaining ball, and the outer wall of the retaining ball is slidably connected to the outer wall of the hollow column.
[0017] As a further description of the above technical solution:
[0018] A sliding ring is fixedly connected to the outer wall of the button, and the outer wall of the sliding ring is slidably connected to the inner wall of the hollow column.
[0019] As a further description of the above technical solution:
[0020] The sliding ring sidewall is provided with a first spring, one end of which is fixedly connected to the sliding ring sidewall and the other end of which is fixedly connected to the outer wall of the button.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the rotating wheel is driven to move by the pressure of the power cord. The movement of the rotating wheel drives the empty slot plate to move. Then, the empty slot plate drives the sliding column on the side wall to slide inside the support plate. During the process of the sliding column being subjected to force, the second spring on the outer wall will contract, achieving the effect of adaptive pressure guidance. This solves the problem of uneven pressure during the twisting process due to the lack of adaptive pressure function, which causes the wire to be unstable, affecting production efficiency and product quality, and improves the stability of the DC power cord twisting machine.
[0023] In this invention, pressing the button moves the trapezoidal column at one end, and at the same time, the side wall of the trapezoidal column disengages from the retaining ball, causing its outer wall to disengage from the hollow column. Simultaneously, the sliding ring moves as the button is pressed, and then the sliding ring retracts the first spring on the side wall, allowing the twisted head to be disassembled. This achieves the effect of quickly disassembling the twisted head, solving the problem of needing to stop the machine for a long time when the twisted head needs to be replaced, which affects the production process, reduces work efficiency, and improves the convenience of the DC power cord twisting machine.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a DC power cord twisting machine, including a bracket 1. The bracket 1 supports all components of the DC power cord twisting machine, ensuring the stability and reliability of the equipment, thereby effectively supporting and fixing the motor 5, transmission system and guide assembly, achieving stable operation. A transmission shaft 3 is fixedly connected to the top of the bracket 1, and a fixing plate 4 is fixedly connected to the bottom of the bracket 1. A motor 5 is fixedly connected to the bottom of the fixing plate 4. The motor 5, in conjunction with the first transmission wheel 6, transmits power and drives the second transmission wheel 8 to rotate through the synchronous belt 7, thereby driving the twisting head 10 to rotate, realizing the rotation action during the twisting process, thereby achieving the effect of effectively twisting the power cord. The output end of the motor 5 is fixedly connected to the first transmission wheel 6. A support ring 2 is fixedly connected to the top of the bracket 1. The second transmission wheel 8 is rotatably connected to the side wall of the support ring 2. The first transmission wheel 6 and the outer wall of the second transmission wheel 8 are rotatably connected to the synchronous belt 7. A connecting column 9 is fixedly connected to the side wall of the second transmission wheel 8. The twisting head 10 is provided on the side wall of the connecting column 9. A guide assembly is provided on the top of the bracket 1.
[0034] The guiding assembly includes a support plate 22, the bottom of which is fixedly connected to the top of the bracket 1. A sliding column 18 is slidably connected inside the support plate 22. The sliding column 18 slides in conjunction with the slotted plate 20. The pressure applied by the power cord drives the sliding column 18 to move within the support plate 22, simultaneously compressing the second spring 19. This dynamic adjustment achieves adaptive pressure guidance, ensuring uniform pressure during the twisting process, thereby improving twisting stability, avoiding uneven pressure during twisting, ensuring wire stability, and improving production efficiency and product quality. A nut 17 is fixedly connected to the outer wall of the sliding column 18, and the slotted plate 20 is fixedly connected to one end of the sliding column 18. A rotating wheel 21 is rotatably connected to the inner wall of the slotted plate 20. A spring-loaded assembly is provided on the outer wall of the sliding column 18. The spring-loaded assembly includes a second spring 19, one end of which is fixedly connected to the outer wall of the sliding column 18, and the other end of which is fixedly connected to the side wall of the slotted plate 20.
[0035] Reference Figure 1 , Figure 5 and Figure 6The twisting head 10 consists of a button 12, a trapezoidal column 15, and a retaining ball 16. Pressing the button 12 moves the trapezoidal column 15, releasing the retaining ball 16 and enabling quick replacement of the twisting head 10. This design reduces downtime, improves equipment efficiency, and provides a simple and quick operating experience during replacement. A hollow column 11 is slidably connected to the inner wall of the twisting head 10, and a button 12 is slidably connected to the inner wall of the hollow column 11. One end of the button 12 is fixedly connected to the trapezoidal column 15, and the outer wall of the trapezoidal column 15 is slidably connected to the inner wall of the hollow column 11. A retaining ball 16 is provided on the side wall of the trapezoidal column 15, and the outer wall of the retaining ball 16 is slidably connected to the outer wall of the hollow column 11. A sliding ring 13 is fixedly connected to the outer wall of the button 12, and the outer wall of the sliding ring 13 is slidably connected to the inner wall of the hollow column 11. A first spring 14 is provided on the side wall of the sliding ring 13, with one end fixedly connected to the side wall of the sliding ring 13 and the other end fixedly connected to the outer wall of the button 12.
[0036] Working principle: After the motor 5 is started, its output end drives the first transmission wheel 6 to rotate. The power is transmitted to the second transmission wheel 8 through the synchronous belt 7, causing the second transmission wheel 8 to rotate on the side wall of the support ring 2. In turn, the connecting column 9 drives the twisting head 10 to rotate, realizing the twisting action. When the power line passes through the rotating wheel 21, it will exert pressure on the rotating wheel 21, pushing the rotating wheel 21 to move the slotted plate 20. The slotted plate 20 then drives the sliding column 18 to slide in the support plate 22, while compressing the second spring 19. When the pressure of the power line decreases, the second spring 19 rebounds and pushes the sliding column 18 to reset, causing the rotating wheel 21 to re-fit the power line, realizing adaptive pressure guidance, ensuring uniform pressure during the twisting process, and improving the twisting stability.
[0037] When replacing the twisted head 10, press button 12. Button 12 causes the trapezoidal column 15 to slide inside the hollow column 11, while simultaneously pushing the sliding ring 13 to compress the first spring 14. After the trapezoidal column 15 moves, it disengages from the locking ball 16, and the locking ball 16 exits from the slot on the outer wall of the hollow column 11. At this point, the twisted head 10 can be removed from the connecting column 9. After replacement, release button 12. The first spring 14 rebounds and pushes the sliding ring 13 and button 12 back to their original positions. The trapezoidal column 15 then presses against the locking ball 16 again, causing the locking ball 16 to snap into the slot of the hollow column 11, thus completing the quick fixing of the twisted head 10, reducing downtime and improving the working efficiency of the equipment.
