Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, specifically to a tension roller device and method for shaping the sheathing layer of wires. Background Technology

[0002] In the manufacturing process of wires and cables, the wrapping quality of the shielding and protective layers directly affects the electrical performance and mechanical strength of the product. Currently, the industry commonly adopts multi-layer composite structure designs, with the wrapping process of the metal shielding layer and non-metallic protective layer being a critical step. With the development of fields such as 5G communication and high-voltage power transmission, the requirements for the flatness and uniformity of wire sheathing are increasingly stringent, and traditional wrapping processes can no longer meet the demands of high-end applications. In recent years, various post-processing technologies for sheathing have emerged in the industry, including hot pressing and laser finishing, but these technologies generally suffer from problems such as complex equipment, high costs, or low efficiency.

[0003] Traditional shaping methods use mechanical rolling to extrude the coating layer using multiple sets of rigid rollers. However, in actual use, mechanical rolling devices are prone to stress concentration during the shaping process, resulting in uneven coating thickness and affecting the overall shaping quality. Summary of the Invention

[0006] The above technical solution involves an inner ring rotatably mounted inside a fixed ring. The rotation of the inner ring causes the cleaning brush inside to rotate, cleaning the dust adhering to the outer sheath of the wire and improving subsequent shaping quality. A vacuum cleaner can absorb the swept dust, preventing it from re-adhering to the wire's surface. A tension roller can shape the wire, and a winding roller can wind it up. A mechanical counter records the winding length while the wire is being wound up.

[0007] Preferably, the linkage assembly includes a third gear, a fourth gear, and a first connecting belt. The third gear is rotatably mounted on the outer surface of the outer frame via a rotating shaft. The two fourth gears are meshed on both sides of the third gear. The first connecting belt is connected to the third gear and the second gear respectively via pulleys.

[0008] Preferably, a first motor is fixedly mounted on the outer surface of the outer frame by a fixing bracket, and the output end of the first motor is connected to a third gear.

[0009] Preferably, a first worm gear is fixedly sleeved on the outer surface of the inner ring, a first worm is connected to the bottom of the first gear, and one end of the first worm extends a certain distance outward from the outer frame. A second connecting belt is connected between the fourth gear and the extended end of the first worm through a pulley.

[0010] Preferably, two collars are fixedly sleeved on the outer surface of the inner ring, and multiple rollers are rotatably installed on the inner side of the two collars. The inner walls of the two fixed rings are provided with raceways, and the rollers are arranged inside the raceways.

[0011] Preferably, a mounting base is fixedly installed on the inner side of the outer frame. The surface of the mounting base has a slot. The mounting base has two first screws inside, and the first screws are located inside the slot. The first screws pass through a first moving block, and the first moving block is connected to the pressure roller through a connecting rod. The top ends of the two first screws are fixedly connected to second worm gears. One side of the two second worm gears is meshed with a second worm. A third worm gear is fixedly connected between the two second worms, and one side of the third worm gear is meshed with a third worm.

[0012] Preferably, a movable frame is fixedly installed on the inner side of the outer frame, a second screw is installed inside the movable frame, a second movable block is passed through the second screw, a telescopic rod is fixedly connected to one side of the second movable block, a connecting frame is fixedly connected to one end of the telescopic rod, and a movable roller is installed on the inner side of the connecting frame.

[0013] Preferably, a telescopic spring is installed inside the telescopic rod, and the two ends of the telescopic spring are connected to the inner rod and the outer rod of the telescopic rod. A second motor is fixedly installed on the outer surface of the outer frame through a fixing bracket, and the output end of the second motor is connected to the second screw.

[0014] Preferably, a baking oven is fixedly installed on the inner side of the outer frame by a fixing seat, and a first guide plate and a second guide plate are sequentially fixedly installed inside the outer frame by fixing rods.

[0015] Preferably, a method for shaping the sheath of electrical wires includes the following steps: S1. Clean the impurities on the surface of the wires with a cleaning brush to increase the quality of the shaping; S2. The coating layer of the wire is shaped by a tension roller to increase the smoothness of the coating; S3. The wire is wound up by rotating the take-up roller; S4. The number of rotations of the take-up roller can be recorded by a mechanical counter, which can be used to count the length of the wire.

[0016] Working principle: When using this device, place it in the designated position, extend the wire to be shaped sequentially between the inner ring, baking chamber, pressure roller and tension roller, and wrap it around the outer surface of the take-up roller. Turn on the first motor, which drives the third gear to rotate. The third gear drives the fourth gears on both sides to rotate synchronously in the same direction. The fourth gears can drive the tension roller to rotate through the transmission rod. Through the rotation of the tension roller, a relatively uniform stress can be applied to the outer coating layer of the wire, thereby shaping the wire. Before shaping, by opening the baking chamber, the outer coating layer of the wire can be heated, making the coating layer softer, which is more conducive to shaping and increases the quality of shaping. When the third gear rotates, it can drive the second gear to rotate via the first connecting belt. The second gear can drive the take-up roller to take up the wire. At the same time, the second gear can drive the first gear at the bottom to rotate. The number of rotations of the first gear can be recorded by a mechanical counter, which can then record the number of rotations of the take-up roller. By multiplying the number of rotations of the take-up roller by the circumference of the take-up roller, the winding length of the wire can be obtained. When the third gear drives the fourth gear to rotate, the fourth gear can drive the first worm to rotate via the second connecting belt. The first worm drives the first worm wheel to rotate, and the first worm wheel drives the inner ring, which is fixedly connected to the inside, to rotate inside the fixed ring. When the inner ring rotates, it can drive the cleaning brush to rotate. The cleaning brush can sweep away the dust attached to the outer sheath of the wire. When the vacuum cleaner is turned on, it can absorb the swept dust through the suction pipe and suction port, preventing dust and other impurities from re-attaching to the surface of the wire and affecting the shaping quality.

[0017] This invention provides a tension roller device and method for shaping the coating layer of electrical wires. It has the following beneficial effects: 1. In this invention, a tension roller is used to shape the wire covered with a coating layer, so that the coating layer is more evenly covered, thereby improving the overall quality and appearance of the wire. By balancing the tension in all directions, the tension roller can prevent stress concentration, thereby further ensuring the quality of wire shaping.

[0018] 2. In this invention, a cleaning brush is installed on the inner side of the inner ring. The inner ring drives the cleaning brush to rotate, which can remove dust and impurities from the outer surface of the wire. This can prevent dust and other impurities from getting stuck between the coating layer and the tension roller, which would cause dents on the surface of the coating layer and affect the shaping quality.

[0019] 3. In this invention, when cleaning dust and impurities from the surface of the conductor, a vacuum cleaner can be used to absorb the cleaned dust, preventing the scattered dust from re-attaching to the surface of the conductor sheath and affecting the shaping quality.

[0020] 4. In this invention, by setting up a linkage component, the tension roller can rotate to shape the wire while simultaneously driving the take-up roller to rotate and take up the wire, thereby increasing the linkage during use.

[0021] 5. In this invention, when the second gear drives the take-up roller to rotate and the wire is wound up, the second gear can drive the first gear to rotate. The number of rotations of the first gear can be recorded by a mechanical counter, and thus the number of rotations of the take-up roller can be recorded. In this way, the winding length of the wire can be recorded while the wire is being wound up.

[0022] 6. In this invention, the rotation of the first screw can drive the first moving block to move, the first moving block can drive the connecting rod to rise and fall, the connecting rod can drive the pressure roller to rise and fall, thereby adjusting the gap between the pressure roller and the tension roller, making it convenient for personnel to pass the wire through the gap between the pressure roller and the tension roller, and at the same time, the pressure of the pressure roller on the wire can also be adjusted.

[0023] 7. In this invention, the second moving block can be driven to move back and forth by the forward and reverse rotation of the second screw. The second moving block can drive the connecting frame and the moving roller to move back and forth by the telescopic rod. By moving back and forth by the moving roller, the winding wire can be bent and deviated on the winding roller, thereby preventing the wire from accumulating at one place on the winding roller when winding the wire, thus affecting the winding process.

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4This invention provides a tension roller device for shaping the sheath of electrical wires, comprising an outer frame 1. Two fixing rings 10 are fixedly installed on the inner side of the outer frame 1 via fixing rods 23. An inner ring 25 is provided between the two fixing rings 10, and the fixing rings 10 are sleeved on the outer side of the inner ring 25. A cleaning brush 26 is installed on the inner wall of the inner ring 25. A vacuum cleaner 2 is installed on the top of the outer frame 1. Two suction pipes 24 are connected to one side of the vacuum cleaner 2. A suction port 28 is provided through the inner wall of the inner ring 25, and one end of the suction pipe 24 is connected to the suction port. The opening 28 is connected. Two tension rollers 21 are provided on the inner side of the outer frame 1. A pressure roller 20 is provided on the top of the tension roller 21. A take-up roller 13 is provided on the inner side of the outer frame 1. A second gear 6 is connected to one side of the take-up roller 13. A first gear 5 is meshed with the bottom of the second gear 6. A mechanical counter 4 is fixedly installed on the outer surface of the outer frame 1 through a fixing frame. The end of the mechanical counter 4 is connected to the first gear 5. A transmission rod 31 is fixedly connected to one side of the two tension rollers 21. A linkage component is connected to one end of the transmission rod 31.

[0028] Specifically, the inner side of the outer frame 1 has a slot for mounting components. The inner ring 25 is movably mounted inside the fixed ring 10, allowing the inner ring 25 to rotate inside the fixed ring 10. When the inner ring 25 rotates, it drives the cleaning brush 26 inside to rotate. The cleaning brush 26 used in this device is made of nylon, whose softness prevents scratching the outer sheath of the wire. In use, the wire can be passed through the hole in the center of the inner ring 25. The rotation of the cleaning brush 26 can sweep away the dust on the surface of the wire, preventing the dust on the surface of the sheath from affecting the subsequent shaping quality. When shaping the wire, the wire can be passed between the tension roller 21 and the pressure roller 20. The rotation of the tension roller 21 and the pressure roller... The calendering process of 20 allows for the shaping of the wire. The shaping via the tension roller 21 reduces stress concentration and improves the quality of the wire shaping. The vibration of the take-up roller 13 winds up the shaped wire. When the take-up roller 13 rotates, it drives the second gear 6, which in turn drives the first gear 5. The counting end of the mechanical counter 4 is connected to the first gear 5. Therefore, when the first gear 5 rotates, the mechanical counter 4 detects the number of rotations of the first gear 5, thus recording the number of rotations of the take-up roller 13. Multiplying the number of rotations by the circumference of the take-up roller 13 yields the winding length of the wire by the take-up roller 13, enhancing the linkage performance of the device during use.

[0029] Please see the appendix Figure 3 The linkage assembly includes a third gear 8, a fourth gear 9, and a first connecting belt 15. The third gear 8 is rotatably mounted on the outer surface of the outer frame 1 via a rotating shaft. The two fourth gears 9 are meshed and mounted on both sides of the third gear 8. The first connecting belt 15 is connected to the third gear 8 and the second gear 6 respectively via pulleys.

[0030] Specifically, when the third gear 8 rotates, it drives the fourth gears 9 on both sides to rotate synchronously in the same direction. When the two fourth gears 9 rotate, they drive the transmission rod 31 fixedly connected to it on one side to rotate. The transmission rod 31 drives the two tension rollers 21 to rotate. When the tension rollers 21 rotate, the wire can be evenly stressed in the circumferential direction, thus ensuring the stable operation of the shaping process. When the third gear 8 rotates, it can drive the second gear 6 to rotate through the transmission of the first connecting belt 15. Thus, in actual use, the shaping, winding and meter counting can be carried out synchronously, further enhancing the linkage of this device.

[0031] Please see the appendix Figure 1 and attached Figure 3 The outer surface of the outer frame 1 is fixedly mounted with a first motor 7 by a fixing bracket, and the output end of the first motor 7 is connected to the third gear 8.

[0032] Specifically, by turning on the first motor 7, the first motor 7 can drive the third gear 8 to rotate, thereby synchronizing the operation of shaping, winding and metering.

[0033] Please see the appendix Figure 3 The outer surface of the inner ring 25 is fixedly fitted with a first worm gear 22, the bottom of the first gear 5 is connected to a first worm 27, and one end of the first worm 27 extends a distance to the outside of the outer frame 1. The fourth gear 9 and the extended end of the first worm 27 are connected by a second connecting belt 16 through a pulley.

[0034] Specifically, the first worm 27 is meshed with the first worm wheel 22, and the first worm 27 is rotatably mounted on the inner side of the outer frame 1 via a rotating shaft, thereby ensuring the stable rotation of the first worm 27 on the inner side of the outer frame 1. When the first worm 27 rotates, it drives the first worm wheel 22 to rotate, which in turn drives the inner ring 25 to rotate stably on the inner side of the fixed ring 10, thereby causing the cleaning brush 26 on the inner side of the inner ring 25 to rotate. Furthermore, through the setting of the second connecting belt 16, when the third gear 8 drives the fourth gear 9 to rotate, the fourth gear 9 can drive the first worm 27 to rotate through the transmission of the second connecting belt 16, thereby ensuring the synchronous operation of the device in winding, counting, shaping, and cleaning, further increasing the linkage during use.

[0035] Please see the appendix Figure 5 and attached Figure 6 Two collars 29 are fixedly sleeved on the outer surface of the inner ring 25. Multiple rollers 30 are rotatably installed on the inner side of the two collars 29. The inner wall of the two fixed rings 10 is provided with a raceway 38, and the rollers 30 are located inside the raceway 38.

[0036] Specifically, when the inner ring 25 rotates inside the fixed ring 10, the roller 30 can roll inside the raceway 38. Since the roller 30 is located inside the raceway 38, it can limit the position of the collar 29, thus limiting the position of the inner ring 25 and ensuring the stability of the inner ring 25's rotation inside the fixed ring 10. Furthermore, a cavity is provided between the outer wall of the inner ring 25 and the inner wall of the fixed ring 10. When the vacuum cleaner 2 is turned on, its negative pressure suction can be transmitted to the cavity between the inner ring 25 and the fixed ring 10, and then through the suction port 28, the cleaned dust is adsorbed. This prevents the dust cleaned by the cleaning brush 26 from continuously drifting and re-adhering to the surface of the wire, thus affecting the shaping quality.

[0037] Please see the appendix Figure 2 and attached Figure 7 An mounting base 18 is fixedly installed on the inner side of the outer frame 1. The surface of the mounting base 18 has a slot. The mounting base 18 has two first screws 32 inside, and the first screws 32 are located inside the slot. The first screws 32 pass through a first moving block 33, and the first moving block 33 is connected to the pressure roller 20 through a connecting rod 19. The top ends of the two first screws 32 are fixedly connected to second worm gears 34. A second worm 35 is meshed with one side of the two second worm gears 34. A third worm gear 36 is fixedly connected between the two second worm gears 35. A third worm 37 is meshed with one side of the third worm gear 36.

[0038] Specifically, the first movable block 33 is threadedly connected to the first screw 32, so that when the first screw 32 rotates, it can drive the first movable block 33 to move on the first screw 32. The surface of the mounting base 18 has a slot, and the first movable block 33 is slidably connected to the inner wall of the slot, thus ensuring the stability and directional accuracy of the first movable block 33 during movement and preventing the first movable block 33 from rotating due to the rotation of the first screw 32. One end of the third worm gear 37 extends upwards a certain distance, and a rotating ring is fixedly connected to the extended end, thus facilitating the rotation of the third worm gear 37 by personnel. Furthermore, when the third worm 37 rotates, it can drive the third worm wheel 36 to rotate. The third worm wheel 36 drives the second worms 35 on both sides to rotate. The second worms 35 drive the second worm wheel 34 to rotate. The second worm wheel 34 drives the two first screws 32 to rotate synchronously. The first screws 32 drive the first moving block 33 to move synchronously on the first screws 32. The first moving block 33 can drive the pressure roller 20 to rise and fall through the connecting rod 19, thereby adjusting the height of the pressure roller 20, which facilitates the passing of the wire between the pressure roller 20 and the tension roller 21. At the same time, the pressure of the pressure roller 20 can also be adjusted, increasing its functionality.

[0039] Please see the appendix Figure 2 and attached Figure 8A movable frame 12 is fixedly installed on the inner side of the outer frame 1. A second screw 39 is installed inside the movable frame 12. A second movable block 40 is passed through the second screw 39. A telescopic rod 41 is fixedly connected to one side of the second movable block 40. A connecting frame 42 is fixedly connected to one end of the telescopic rod 41. A movable roller 43 is installed on the inner side of the connecting frame 42.

[0040] Specifically, the second movable block 40 is connected to the second screw 39 by a thread, so that when the second screw 39 rotates, it can drive the second movable block 40 to move on the second screw 39. The movable frame 12 has a slot for the second movable block 40 to move and the second screw 39 to rotate. When the second movable block 40 moves, it can drive the telescopic rod 41 to move. The telescopic rod 41 can drive the movable roller 43 to move through the connecting frame 42. When winding the wire, the wire can be extended into the inside of the movable roller 43. Through the reciprocating movement of the movable roller 43, the wound wire can be bent. When the wire bends at the top of the winding roller 13, the winding range of the wire around the winding roller 13 can be increased, thereby preventing the wire from accumulating at one place on the winding roller 13 and affecting the winding process.

[0041] Please see the appendix Figure 8 and attached Figure 9 The telescopic rod 41 is equipped with a telescopic spring 44 inside, and the two ends of the telescopic spring 44 are connected to the inner rod and the outer rod of the telescopic rod 41. The outer surface of the outer frame 1 is fixedly installed with a second motor 11 through a fixing bracket, and the output end of the second motor 11 is connected to the second screw 39.

[0042] Specifically, when the take-up roller 13 takes up the wire, as the number of turns increases, the wire becomes thicker on the outside of the take-up roller 13. When the wire becomes thicker, it will squeeze the moving roller 43. The moving roller 43, when squeezed, will squeeze the telescopic rod 41 inward. The inner rod of the telescopic rod 41 squeezes the telescopic spring 44 inward. This allows the telescopic rod 41 to retract inward while ensuring that the inner side of the moving roller 43 is always in contact with the wire, thus ensuring the normal operation of the take-up.

[0043] Please see the appendix Figure 1 and attached Figure 2 The baking oven 3 is fixedly installed on the inner side of the outer frame 1 by a fixing seat, and the first guide plate 14 and the second guide plate 17 are fixedly installed in sequence on the inside of the outer frame 1 by fixing rods 23.

[0044] Specifically, when shaping the conductor, the conductor can be extended into the inner side of the baking oven 3. By opening the baking oven 3, the baking oven 3 can heat the coating layer of the conductor, thereby softening the coating layer. During the subsequent shaping by the tension roller 21, the stress can be evenly applied to the surface of the coating layer, and the shaping of the coating layer is convenient. This can further enhance the shaping effect of the conductor. The first guide plate 14 and the second guide plate 17 are arranged one below and one above the inner side of the outer frame 1, so the conductor can be in a bent state during guidance. This allows the bending performance of the conductor to be detected, and also increases the directionality and stability of the conductor during winding.

[0045] Please see the appendix Figure 1 - Appendix Figure 10 A method for shaping the sheathing layer of electrical wires, the method comprising the following steps: S1. Clean the impurities on the surface of the wire by using the cleaning brush 26 to increase the quality of the shaping; S2. The coating layer of the wire is shaped by the tension roller 21 to increase the flatness of the coating; S3. The wire is wound up by rotating the take-up roller 13; S4. The number of rotations of the take-up roller 13 can be recorded by the mechanical counter 4, which can be used to count the length of the wire.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
