Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, and in particular to a wrapping device for processing MPP cable pipes. Background Technology
[0002] Cable protection pipes primarily serve to protect cables. During processing, a thin film is wrapped around the ends of the pipes to enhance protection and waterproofing. The ends of the pipes are prone to wear, deformation, and damage. The film provides an extra protective layer, improving protection and preventing damage and corrosion from the external environment. The film material can be chosen according to actual needs; common materials include polyethylene film and polyvinyl chloride film.
[0003] During the processing, the film is usually tightly wrapped around the surface of the cable protection pipe, so that it fits tightly and covers the entire pipe. This can enhance the waterproof and corrosion-resistant properties of the cable protection pipe and extend its service life. However, in the actual processing, if the tension of the film is uneven, it will lead to uneven wrapping, resulting in too much film overlap or some exposed areas. Utility Model Content
[0004] To address the technical problem that uneven tension during actual processing can lead to uneven wrapping, excessive film overlap, or partial exposure, this invention provides a wrapping device for processing MPP cable pipes.
[0005] This utility model is achieved using the following technical solution: a wrapping device for processing MPP cable pipes, including a worktable, a fixed plate at the top of the worktable, an installation hole on the worktable surface, the outer side of the fixed plate being fixed to the inner sidewall of the installation hole, an opening in the middle of the fixed plate for the cable pipe to pass through, an internal gear rotatably arranged around the opening on one side of the fixed plate, an installation shaft rotatably connected to the outer side of the internal gear, and a wrapping roller for providing wrapping for the cable pipe being installed on the outer side of the installation shaft.
[0006] With the above technical solution, a rotatable internal gear is provided on one side of the fixed plate, and a rotatable mounting shaft is provided on the outside of the internal gear. This allows the film-wrapping roller on the outside of the mounting shaft to rotate in the opposite direction while following the rotation of the internal gear, thereby releasing the film and achieving uniform tension on the film wrapped around the outside of the cable pipe.
[0007] As a further improvement to the above solution, a connecting plate is fixedly connected to the other side of the fixed plate. The connecting plate is provided with a drive assembly for driving the internal gear to rotate on one side of the wrapping roller. Multiple limiting blocks are installed on one side of the fixed plate. Limiting grooves are opened on the side of the limiting blocks, and the outer side of the internal gear slides in the limiting grooves.
[0008] Through the above technical solution, limit grooves are opened on multiple limit blocks installed on one side of the fixed plate, so as to limit the rotation of the internal gear and continuously slide inside the multiple limit grooves, so that the internal gear always maintains the same position to rotate, ensuring uniform tension on the film wrapped around the outside of the cable pipe.
[0009] As a further improvement to the above solution, the drive assembly includes a connecting shaft rotatably connected to the middle of the connecting plate, a first servo motor coaxial with the connecting shaft is fixedly connected to the side of the connecting plate away from the fixed plate, and a transmission gear meshing with an internal gear is fixedly connected to the end of the connecting shaft.
[0010] Through the above technical solution, the first servo motor fixed on the connecting plate in the drive assembly can drive the connecting shaft and the transmission gear meshing with the internal gear at the end of the connecting shaft to rotate, and synchronously drive the internal gear to rotate on the fixed plate.
[0011] As a further improvement to the above solution, a slide groove is provided at the top of the workbench, and a reciprocating screw is rotatably connected inside the slide groove. A second servo motor coaxial with the reciprocating screw is fixed to one vertically parallel side of the workbench. A moving block is connected to the outer nut pair of the reciprocating screw. A collar for limiting and clamping the cable pipe is fixed to the top of the moving block. A U-shaped frame for supporting the cable pipe is fixed to the top of the workbench.
[0012] Through the above technical solution, when the collar is moved through the top of the moving block, the second servo motor drives the reciprocating screw to rotate, which in turn drives the end of the cable tube that is limited inside the collar to move, so as to realize the multi-distance film winding of the cable tube end.
[0013] As a further improvement to the above solution, the inner bottom ends of the U-shaped frame and the collar are at the same height, and the center height of the cable pipe that is limited inside the collar and the inner bottom end of the U-shaped frame is the same as the center height of the internal gear.
[0014] Through the above technical solution, the inner bottom heights of the U-shaped frame and the collar are consistent, so that the height of the cable pipe center is consistent with the height of the internal gear, ensuring that the distance of the film coating roller on the outer side of the cable pipe is consistent when the film coating roller rotates with the internal gear.
[0015] As a further improvement to the above solution, the reciprocating lead screw is located inside the internal gear, and the distance from the bottom of the internal gear to the reciprocating lead screw is greater than the diameter of the wrapping roller.
[0016] The above technical solution ensures that when the stretch film rotates to the bottom of the internal gear, it can pass smoothly between the mounting hole and the reciprocating screw.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention features a rotatable internal gear on one side of a fixed plate and a rotatable mounting shaft on the outside of the internal gear. This allows the wrapping roller on the outside of the mounting shaft to rotate in the opposite direction while simultaneously releasing the wrapping film, thus achieving uniform tension on the film wrapped around the outside of the cable conduit. Limiting grooves are provided on the limiting blocks on one side of the fixed plate to limit the rotation of the internal gear and allow it to slide continuously within multiple limiting grooves. This ensures that the internal gear rotates in the same position at all times, further guaranteeing uniform tension on the film wrapped around the outside of the cable conduit.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Please combine Figures 1-4This embodiment of a wrapping device for processing MPP cable conduits includes a worktable 1, a fixed plate 2 at the top of the worktable 1, and mounting holes 3 on the surface of the worktable 1. The outer side of the fixed plate 2 is fixed to the inner wall of the mounting holes 3. An opening 4 for cable conduit passage is opened in the middle of the fixed plate 2. An internal gear 5 is rotatably arranged around the opening 4 on one side of the fixed plate 2. An installation shaft 6 is rotatably connected to the outer side of the internal gear 5. A wrapping roller 7 for providing wrapping film to the cable conduit is installed on the outer side of the installation shaft 6. By providing a rotatable internal gear 5 on one side of the fixed plate 2 fixed inside the mounting holes 3 and opening 4 for cable conduit passage in the middle of the fixed plate 2, the installation shaft 6 rotatably connected to the outer side of the internal gear 5 rotates around the midpoint of the opening 4 while following the internal gear 5. At the same time, the wrapping film installed on the outer side of the installation shaft 6 can rotate in the opposite direction to release the wrapping film, thereby achieving a film with uniform tension wrapped around the outer side of the cable conduit.
[0027] Combination Figures 2-4 A connecting plate 8 is fixedly connected to the other side of the fixed plate 2. The connecting plate 8, located on one side of the wrapping roller 7, has a drive assembly for rotating the internal gear 5. Multiple limiting blocks 9 are installed on one side of the fixed plate 2. Limiting grooves 10 are formed on the side of each limiting block 9. The outer side of the internal gear 5 slides within the limiting grooves 10. The drive assembly includes a connecting shaft 11 rotatably connected to the middle of the connecting plate 8. A first servo motor 12, coaxial with the connecting shaft 11, is fixedly connected to the side of the connecting plate 8 away from the fixed plate 2. An internal gear 5 is fixedly connected to the end of the connecting shaft 11. The meshing transmission gears; the first servo motor 12, which is fixed to the side of the connecting plate 8 away from the fixed plate 2, drives the connecting shaft 11, which is rotatably connected to the middle of the connecting plate 8, to rotate, so that the transmission gear 13 at the end of the connecting shaft 11 can drive the meshing internal gear 5 to rotate. Since multiple limit blocks 9 installed on one side of the fixed plate 2 have limit grooves 10, when the internal gear 5 rotates, it slides synchronously inside the limit grooves 10 opened by multiple limit blocks 9, so that the internal gear 5 always maintains the same position to rotate.
[0028] Combination Figures 1-3The top of the worktable 1 has a slide groove 14, and a reciprocating screw 15 is rotatably connected inside the slide groove 14. A second servo motor 16, coaxial with the reciprocating screw 15, is fixed to one vertically parallel side of the worktable 1. A moving block 17 is connected to the outer nut pair of the reciprocating screw. A collar 18 for limiting and clamping the cable pipe is fixed to the top of the moving block 17. A U-shaped frame 19 for supporting the cable pipe is fixed to the top of the worktable 1. The inner bottom ends of the U-shaped frame 19 and the collar 18 are at the same height, and the center of the cable pipe limited inside the collar 18 is located at the inner bottom end of the U-shaped frame 19. The height is the same as the center height of the internal gear 5. The reciprocating screw is located inside the internal gear 5, and the distance from the bottom of the internal gear 5 to the reciprocating screw is greater than the diameter of the wrapping roller 7. The second servo motor 16 drives the reciprocating screw 15 inside the slide groove 14 at the top of the worktable 1 to rotate, so that the moving block 17 connected to the nut pair on the outside of the reciprocating screw 15 drives the cable tube limited inside the collar 18 to move. At the same time, the other end of the moving cable tube slides on the inner top of the U-shaped frame 19, so that the cable tube can be evenly received by the wrapping roller 7 for outer film coating while moving.
[0029] The implementation principle of the wrapping device for processing MPP cable pipes in this application embodiment is as follows: Before operation, the cable pipe is passed through the inside of the U-shaped frame 19 on the top of the workbench 1 until one end of the cable pipe passes through the collar 18 located at the top of the moving block 17, and the cable pipe is left with the length to be covered. At this time, the first servo motor 12 fixed to the side of the connecting plate 8 away from the fixed plate 2 is activated to drive the connecting shaft 11 rotatably connected to the middle of the connecting plate 8 to rotate, so that the transmission gear 13 at the end of the connecting shaft 11 can drive the meshing internal gear 5 to rotate. Since multiple limit blocks 9 installed on one side of the fixed plate 2 are provided with limit grooves 10, when the internal gear 5 rotates, it slides synchronously in the limit grooves 10 provided by multiple limit blocks 9, so that the internal gear 5 always maintains the same position to rotate. At this time, the mounting shaft 6 is rotatably connected to the outside of the internal gear 5, and the wrapping roller 7 is installed on the outside of the mounting shaft 6. The film-coating roller 7 rotates in a circular motion around the midpoint of the opening 4, following the internal gear 5. At the same time, the film on the film-coating roller can rotate in the opposite direction to release the film, thus achieving uniform tension on the outer side of the cable tube end. Then, the second servo motor 16 on the outer side of the vertical parallel worktable 1 drives the reciprocating screw 15 to rotate. The slide groove 14 is opened at the top of the worktable 1, so that the moving block 17 connected to the nut pair on the outer side of the reciprocating screw 15 drives the cable tube limited inside the collar 18 to move, which can cover the cable tube end with different lengths as required.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
