Description

Technical Field

[0001] This invention relates to the field of stranded wire technology, specifically to a high-efficiency stranded wire device for wire production. Background Technology

[0002] During the manufacturing process of electrical wires, multiple strands of conductive wires are basically twisted together. This not only ensures that the wires can be used for a long time, but also ensures the strength of the wires. In order to quickly twist the wires and ensure that the twisted wires are of consistent shape, specific equipment is usually required during the twisting process.

[0003] Current high-efficiency stranding devices have certain shortcomings;

[0004] During the stranding process of electrical wires, multiple strands of conductive wires are rotated and their ends are fixed to twist them together. However, some conductive wires may become loose during the stranding process, resulting in an unsatisfactory stranding effect. After stranding, these wires need to be collected. The existing collection methods mostly involve winding the wires together. However, if the speed is not controlled properly during winding, the wires may be pulled too fast, affecting the stranding process.

[0005] Meanwhile, during the pulling process, these wires can easily get stuck at the outlet of the equipment. If these wires get stuck during the winding process, it will cause the motor driving the winding drum to be overloaded, which can easily lead to damage to the motor. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency stranding device and method for wire production, addressing the issues raised in the background art. In the stranding process, multiple conductive wires are typically rotated and their ends fixed to achieve stranding. However, some conductive wires tend to loosen during stranding, resulting in less than ideal stranding performance. Furthermore, after stranding, these wires need to be collected. Existing collection methods mostly involve winding the wires together, but if the speed is not properly controlled, the wires can be pulled too quickly, affecting the stranding process. Additionally, during the pulling process, these wires can easily get stuck at the exit point.

[0016] Compared with the prior art, the present invention provides a high-efficiency stranding device for wire production, which has the following advantages:

[0017] 1. This invention, through the cooperation of an electric cylinder, a first arc-shaped plate, an outer sleeve, an inner sleeve rod, a fixed plate, a horizontal plate, a pressure cylinder, a fixed ring, a rotating rod, a limiting block, a hinge block, and a first spring, can uniformly pull these stranded wires during the wire production process, ensuring that these stranded wires can be output evenly. Furthermore, after pulling these stranded wires a certain distance, it can drive the pressure cylinder to move in the opposite direction without affecting the pulling of the stranded wires, so that the pressure cylinder performs a certain pressing work on the outer side of the stranded wires, ensuring the stability of these stranded wires and preventing the stranded wires from becoming loose.

[0018] 2. Under the action of the locking block, rotating drum, rotating shaft, locking groove, mounting groove, and second spring, this invention can evenly collect the stranded wires after they are twisted and wound around the outside of the winding drum. During the winding process, if the stranded wires get stuck at a certain point, the connection between the rotating drum and the winding drum will be temporarily loosened, so that the rotating drum will no longer drive the winding drum to rotate. This avoids the situation where the stranded wires are stuck but the winding drum continues to rotate, thus protecting the second drive motor and preventing it from being damaged due to excessive load.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0029] Please see Figure 1-8This invention provides a technical solution: a high-efficiency stranding device for wire production, comprising a base plate 1, a base 8 on one side of the base plate 1, a stranding drum 30 on the top of the base 8, a large pulley 9 on the outer side of the stranding drum 30, a placement frame 6 in the middle of the top of the base plate 1, a small pulley 5 inside the placement frame 6, a belt 10 between the outer sides of the small pulley 5 and the large pulley 9, a first drive motor 7 on one side of the placement frame 6, a sliding groove 31 in the middle of the top of the base plate 1, a sliding seat 3 slidably connected inside the sliding groove 31, a movable frame 2 on the top of the sliding seat 3, a first arc plate 11 on the top of the movable frame 2, outer sleeves 20 symmetrically arranged at both ends of the first arc plate 11, and an inner sleeve rod 21 slidably connected inside the outer sleeve 20. The top of the sleeve rod 21 is provided with a fixing plate 22, and a second arc plate 12 is provided between the two sets of fixing plates 22. Limiting components are provided at the second arc plate 12 and the first arc plate 11. An electric cylinder 4 is provided on one side of the top of the base plate 1. The output end of the electric cylinder 4 is connected to the moving frame 2. An outer chamber 14 is provided on the top of the base plate 1. A connecting plate 13 is provided at the bottom of the outer chamber 14. Guide grooves 19 are symmetrically provided on both sides of the connecting plate 13. A moving frame 18 is provided on the top of the second arc plate 12. Sliding blocks 32 are symmetrically provided at both ends inside the moving frame 18.

A winding drum 15 is provided inside the fixing frame 17. A protective component is provided on the outside of the winding drum 15.

[0030] As a preferred embodiment, the limiting assembly comprises a horizontal plate 23, a pressure cylinder 24, a fixing ring 25, a rotating rod 26, a limiting block 27, a hinge block 28, and a first spring 29. A horizontal plate 23 is provided at the second arc-shaped plate 12 and the first arc-shaped plate 11. A fixing ring 25 is provided on one side of the horizontal plate 23. A pressure cylinder 24 is provided between the two sets of horizontal plates 23. A rotating rod 26 is provided inside the pressure cylinder 24. Multiple sets of hinge blocks 28 are evenly hinged to the outside of the rotating rod 26. A first spring 29 is provided on one side of the hinge block 28. 29 is connected to the rotating rod 26. Multiple sets of limiting blocks 27 are evenly arranged inside the fixing ring 25. During the wire production process, these stranded wires can be pulled at a uniform speed to ensure that these stranded wires can be output evenly. After pulling these stranded wires a certain distance, the pressure cylinder 24 can be driven to move in the opposite direction without affecting the pulling of the stranded wires. This allows the pressure cylinder 24 to perform a certain pressing work on the outside of the stranded wires, ensuring the stability of these stranded wires and preventing the stranded wires from becoming loose.

[0031] As a preferred embodiment, the protective assembly comprises a locking block 33, a rotating drum 34, a rotating shaft 35, a locking groove 36, a mounting groove 37, and a second spring 38.

A rotating drum 34 is located on the outer side of the winding drum 15, and multiple locking grooves 36 are evenly distributed on the inner side of the rotating drum 34. A rotating shaft 35 is located on one side of each locking groove 36. The output end of the second drive motor 16 is connected to the rotating shaft 35 during the winding process. After completion, the stranded wires can be evenly collected and wound around the outside of the winding drum 15. During the winding process, if the stranded wires get stuck at any point, the connection between the rotating drum 34 and the winding drum 15 will temporarily loosen. This prevents the rotating drum 34 from driving the winding drum 15 to rotate, thus avoiding a situation where the stranded wires are stuck while the winding drum 15 continues to rotate. This protects the second drive motor 16 from excessive load and potential damage.

[0032] As a preferred embodiment, one side of the guide groove 19 is made of an upwardly inclined structure, and the sliding block 32 is located inside the guide groove 19. The guide groove 19 and the sliding block 32 are adapted to each other, which facilitates the guidance of the movement of the second arc plate 12.

[0033] As a preferred embodiment, the bottom of the sliding seat 3 is supported by a T-shaped structure, and a limiting groove is provided on the inner side of the sliding groove 31. The bottom of the sliding seat 3 is located inside the limiting groove to limit the position of the sliding seat 3.

[0034] As a preferred embodiment, the inner side of the rotating drum 34 is provided with a limiting ring, and the outer side of the winding drum 15 is provided with a limiting ring groove, with the limiting ring located inside the limiting ring groove, which facilitates the limiting of the winding drum 15.

[0035] As a preferred embodiment, one end of the fixing frame 17 is provided with a mounting hole, and one end of the rotating shaft 35 extends through the mounting hole to one end of the fixing frame 17 and is connected to the output end of the second drive motor 16. The outer side of the second drive motor 16 is provided with a motor compartment to facilitate connection.

[0036] As a preferred embodiment, the top of the base 8 is made of an arc-shaped groove structure, the stranding drum 30 is located inside the base 8, and multiple sets of connecting holes are evenly provided on one side of the stranding drum 30, which facilitates subsequent stranding work.

[0037] As a preferred embodiment, the electric cylinder 4 is provided with a support frame on one side, and the electric cylinder 4 is connected to the base plate 1 through the support frame. The output end of the electric cylinder 4 is provided with a locking plate, and the locking plate is connected to the movable frame 2 by bolts, which facilitates fixed connection.

[0038] Example 1: As Figure 1-8 As shown, during the wire stranding process, multiple strands are first placed sequentially inside the stranding drum 30, and then the strands are pulled to perform preliminary stranding at their ends. The stranded wires are then passed through the second arc-shaped plate 12 and wound around the outside of the winding drum 15, completing the initial assembly. Then, the first drive motor 7 is started, which drives the small pulley 5 to rotate. The small pulley 5, through the belt 10, drives the large pulley 9 and the stranding drum 30 to rotate. As the stranding drum 30 rotates, it drives multiple sets of stranded wires to rotate as well. Since the ends of these wires cannot rotate due to the pressing action of the two pressure cylinders 24, the stranded wires become twisted together as the stranding drum 30 rotates. Then, the electric cylinder 4 is activated, causing it to push the moving frame 2, the first arc plate 11, and the second arc plate 12 to move. During this movement, the first arc plate 11 and the second arc plate 12 uniformly pull the guide ends of the stranded wires. After reaching the designated position, the moving frame 18 moves to the end of the guide groove 19, thereby pulling the second arc plate 12 upward and no longer clamping the stranded wire. At this time, the second drive motor 16 drives the winding drum 15 to rotate, thereby winding these guides around the outside of the winding drum 15. Then, the electric cylinder 4 is activated, and the electric cylinder 4 pulls the moving frame 2, the first arc plate 11 and the second arc plate 12 to move in opposite directions. During the reverse movement, the two sets of pressure cylinders 24 move on the outside of the stranded wire while pressing it. The pressure cylinder 24 drives the rotating rod 26 to rotate clockwise. During the clockwise rotation, the hinge block 28 comes into contact with the limiting block 27 and is flipped under the influence of pressure, thus preventing the rotation of the pressure cylinder 24. During the counterclockwise rotation, the limiting block 27 restricts the hinge block 28, so that the two sets of pressure cylinders 24 can pull the line to move in the pressed state. Conversely, they roll along the outside of the conductor to press the conductor. When the second arc plate 12 moves to the designated position again, it pulls the conductor to move again.

[0039] Example 2: Figure 1-8 As shown, when the guide is stuck and cannot move, the winding drum 15 rotates. At this time, the pressure on the rotation increases, causing the rotating drum 34 to move downward under pressure. During the movement, the second spring 38 is compressed, and at the same time, the locking block 33 disengages from the locking groove 36 and is no longer connected to the rotating drum 34. This prevents the rotating shaft 35 and the rotating drum 34 from driving the winding drum 15 to rotate, thus avoiding the situation where the rotating shaft 35 and the rotating drum 34 continuously drive the winding drum 15 to rotate, which could lead to the second drive motor 16 being damaged due to excessive load.

[0040] Working principle: During the wire stranding process, multiple strands are first placed sequentially inside the stranding drum 30, and then the strands are pulled to perform preliminary stranding at their ends. The stranded wires are then passed through the second arc-shaped plate 12 and wound around the outside of the winding drum 15, completing the initial assembly. Then, the first drive motor 7 is started, which drives the small pulley 5 to rotate. The small pulley 5, through the belt 10, drives the large pulley 9 and the stranding drum 30 to move forward. As the stranding drum 30 rotates, it drives multiple sets of stranded wires to rotate as well. Since the ends of these wires cannot rotate due to the pressing action of the two pressure cylinders 24, the stranded wires become twisted together as the stranding drum 30 rotates. Then, the electric cylinder 4 is activated, causing it to push the moving frame 2, the first arc plate 11, and the second arc plate 12 to move. During this movement, the first arc plate 11 and the second arc plate 12 uniformly pull the guide ends of the stranded wires. After moving to the designated position, the moving frame 18 moves to the end of the guide groove 19, thereby pulling the second arc plate 12 upward and no longer clamping the stranded wire. At this time, the second drive motor 16 drives the winding drum 15 to rotate, thereby winding these guides around the outside of the winding drum 15. Then, the electric cylinder 4 is activated, and the electric cylinder 4 pulls the moving frame 2, the first arc plate 11 and the second arc plate 12 to move in opposite directions. During the reverse movement, the two sets of pressure cylinders 24 move on the outside of the stranded wire while pressing it. The pressure cylinder 24 drives the rotating rod 26 to rotate clockwise. During the clockwise rotation, the hinge block 28 comes into contact with the limiting block 27 and is flipped under the influence of pressure, thus preventing the rotation of the pressure cylinder 24. During the counterclockwise rotation, the limiting block 27 restricts the hinge block 28, so that the two sets of pressure cylinders 24 can pull the line to move in the pressed state. Conversely, they roll along the outside of the conductor to press the conductor. When the second arc plate 12 moves to the designated position again, it pulls the conductor to move again.

[0041] When the guide is stuck and cannot move, the winding drum 15 rotates. At this time, the pressure on the rotation increases, causing the rotating drum 34 to move downward under pressure. During the movement, the second spring 38 is compressed, and the locking block 33 disengages from the locking groove 36 and is no longer connected to the rotating drum 34. This prevents the rotating shaft 35 and the rotating drum 34 from driving the winding drum 15 to rotate, thus avoiding the situation where the rotating shaft 35 and the rotating drum 34 continuously drive the winding drum 15 to rotate, which could lead to the second drive motor 16 being damaged due to excessive load.

[0042] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
