Description

Technical Field

[0001] This utility model relates to the field of traction equipment technology, specifically a traction device for the manufacture of wires and cables. Background Technology

[0002] Cables are typically made up of several or groups of conductors twisted together, resembling ropes. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated. Currently, cable processing and production require the use of cable pulling equipment, which uses winding reels to wind up the cables, thus facilitating their storage and transportation.

[0003] Chinese Patent Publication No. CN219950059U discloses a pulling device for manufacturing wires and cables, comprising: a base; a take-up roller, on which a mounting seat is fixedly mounted, the take-up roller being rotatably mounted on the mounting seat via a first rotating shaft for winding wires and cables; and a pulling mechanism, located on the base, for pulling the wires and cables and winding them orderly onto the take-up roller. This pulling device is simple to operate and convenient to use. First, the pulling mechanism is adjusted according to the actual specifications of the wires and cables to be wound. After adjustment, the wires and cables are wound up by the take-up roller. During this process, the pulling mechanism pulls the wires and cables and winds them orderly onto the take-up roller, effectively solving the problem of messy wire and cable winding.

[0004] However, the aforementioned patents still have certain shortcomings. In actual use, they are not very effective in solving the problem of messy wire and cable winding. Since the wire and cable are wound back and forth layer by layer on the surface of the winding roller during the winding process, the aforementioned pulling mechanism cannot move back and forth with the wire and cable during winding. This results in the wire and cable being tilted between the pulling mechanism and the winding roller during winding, which still easily leads to the problem of messy winding and is quite inconvenient.

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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides a technical solution: a pulling device for manufacturing wires and cables, including a base 1, two vertical plates 2 respectively welded to the front and rear top walls of the right end of the base 1, the middle rod of the rotating rod 4 passing through the top plate of the vertical plate 2 via a bearing, a winding roller 3 installed in the clamping cavity of the two rotating rods 4, and a motor 5 connected to the rear end of the rear rotating rod 4 via a coupling, the motor 5 being fixed to the rear side wall of the rear vertical plate 2 by bolts. A groove 8 is formed in the top wall of the left end of the base 1. The rear end of the reciprocating screw 9 is mounted on the rear side wall of the groove 8 via a bearing, and its front end passes through the front side wall of the groove 8 via a bearing. A movable seat 10 is screwed onto the surface of the reciprocating screw 9. Second guide grooves 20 are formed on both the left and right side walls of the groove 8. Guide posts 21 are welded to both the left and right side walls of the movable seat 10. The ends of the guide posts 21 are slidably connected in the grooves of the second guide grooves 20. The purpose is to allow the movable seat 10 to move back and forth along the reciprocating screw 9 without rotating itself when the reciprocating screw 9 rotates. A wire and cable clamping assembly is provided on the top wall of the movable seat 10. Pulleys 6 are welded to the surface of the front end of the reciprocating screw 9 and the front rotating rod 4. A belt 7 is sleeved between adjacent pulleys 6. The purpose is to allow the rotating rod 4 to drive the reciprocating screw 9 to rotate together when it rotates.

[0023] The cable clamping assembly includes a connecting post 11, a frame 12, a partition plate 13, a first guide groove 14, a bidirectional threaded rod 15, a traction wheel 16, a moving block 17, a fixed post 18, and a first lever 19. The connecting post 11 is welded to the top wall of the moving seat 10, the frame 12 is welded to the top wall of the connecting post 11, and the partition plate 13 is vertically welded inside the frame 12, dividing the inner cavity of the frame 12 into front and rear parts. The bottom end of the bidirectional threaded rod 15 is rotatably connected to the bottom wall of the rear inner cavity of the frame 12 via a bearing, and its top end passes through the top wall of the frame 12 via a bearing. The first lever 19 is welded to the top end of the bidirectional threaded rod 15 to facilitate the rotation of the bidirectional threaded rod 15 via the first lever 19. The first guide groove 14 is formed on the surface of the partition plate 13. Two movable blocks 17 are screwed onto the upper and lower ends of the bidirectional threaded rod 15. The column of the fixed column 18 moves through the cavity of the first guide groove 14, and the rear end of the fixed column 18 is welded to the front side wall of the movable block 17. The traction wheel 16 is welded to the front end of the fixed column 18, that is, the traction wheel 16 is located in the front inner cavity of the frame 12. The purpose is to allow the bidirectional threaded rod 15 to rotate via the first lever 19 when the distance between the two traction wheels 16 needs to be adjusted to accommodate wires and cables of different sizes. Under the limiting guidance of the first guide groove 14 and the fixed column 18, the two movable blocks 17 can move closer or further away from each other, thereby causing the two traction wheels 16 to move closer or further away from each other, thus adjusting the distance between the two traction wheels 16 to accommodate wires and cables of different sizes. A recessed cavity 401 is formed on one end of the rotating rod 4 near the take-up roller 3. Connecting shafts 22, adapted to the recessed cavity 401, are welded to both the front and rear side walls of the take-up roller 3, allowing the connecting shafts 22 to be inserted into the recessed cavity 401. Positioning holes 28 are formed on the surface of the connecting shafts 22. A fixing frame 23 is welded to the surface of the rotating rod 4. A positioning post 25 is installed in the inner cavity of the fixing frame 23. The right end of the positioning post 25 movably penetrates the wall of the fixing frame 23, and the left end of the positioning post 25 movably penetrates the wall of the recessed cavity 401 and is inserted into the cavity of the positioning hole 28. A pressing plate 27, welded to the surface of the positioning post 25, is provided in the inner cavity of the fixing frame 23. A spring 26, sleeved on the surface of the positioning post 25, is provided on the side of the pressing plate 27 away from the connecting shaft 22, to facilitate the automatic reset of the positioning post 25. The right end of the positioning post 25 is welded with a second lever 24, which is used to facilitate the movement of the positioning post 25.

[0024] During the winding and connection of the wire and cable, the motor 5 starts and drives the rotating rod 4 to rotate. Under the action of the connecting shaft 22, the winding roller 3 rotates to wind and pull the wire and cable. Under the transmission effect of the pulley 6 and belt 7, the rotating rod 4 drives the reciprocating screw 9 to rotate together. Under the limiting and guiding action of the second guide groove 20 and the guide post 21, the moving seat 10 moves back and forth along the rod of the reciprocating screw 9 without rotating itself. This allows the frame 12 equipped with the traction wheel 16 to move back and forth along with the winding of the wire and cable, thereby preventing the cable from becoming tilted and preventing the wire and cable from becoming messy during the winding process. When the take-up roller 3 is fully wound and needs to be disassembled and replaced with a new take-up roller 3, the second lever 24 can be pulled to the right to move the positioning post 25 to the right, so that the left end of the positioning post 25 is pulled out from the positioning hole 28 of the connecting shaft 22. During this process, the extrusion plate 27 will squeeze the spring 26. After the positioning post 25 is pulled out, the take-up roller 3 can be disassembled. Releasing the second lever 24 will allow the positioning post 25 to automatically reset under the action of the spring 26. This facilitates the quick installation and disassembly of the take-up roller 3, thereby improving the pulling efficiency of wires and cables.
