Description

Technical Field

[0001] This utility model relates to the field of frame-type stranding machine technology, specifically to a frame-type stranding machine for cable processing. Background Technology

[0002] The frame-type stranding machine is a key piece of equipment in cable processing used for stranding conductors. Its structure revolves around a frame, which rotates to drive multiple conductors to spirally strand around a central axis, thus forming a cable with a certain strength and structural stability. The efficient operation of the take-up system directly affects overall production efficiency and cable quality. The take-up reel, as the core component of the take-up system, is used to wind and collect the stranded cable. When the take-up reel reaches its rated take-up capacity, it must be replaced promptly to ensure continuous production.

[0003] In existing technologies, the take-up reel and spindle are typically fixed using a tapered surface fit and a lock nut. The spindle end is designed with a tapered structure, and the take-up reel's shaft hole is machined into a corresponding tapered hole. The self-locking property of the tapered surface is used for initial positioning and circumferential fixation. Multiple threads are provided at the end of the spindle, and tightening the lock nut axially presses the take-up reel against the tapered surface.

[0004] However, the process of replacing the take-up reel requires tightening and loosening multiple locking nuts in sequence, resulting in low replacement efficiency and consequently affecting the stranding efficiency of the stranding machine. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a frame-type stranding machine for cable processing, which solves the technical problem of low replacement efficiency of the take-up reel fixed by multiple bolts in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a frame-type stranding machine for cable processing, including a base plate, a stranding machine body, a support frame, a main shaft, a first motor, a take-up reel, and a fixing mechanism. The stranding machine body is mounted on the base plate, the support frame is fixedly mounted on the base plate, the main shaft is rotatably mounted on the side wall of the support frame, the first motor is mounted on the support frame, the output end of the first motor is fixedly connected to the main shaft, the take-up reel is fitted onto the main shaft, and the fixing mechanism is disposed between the main shaft and the take-up reel for fixing the main shaft and the take-up reel.

[0007] Preferably, the fixing mechanism includes a fixing block, a fixing slot, and a positioning mechanism. A plurality of fixing blocks are fixedly disposed on the side wall of the main shaft, and a plurality of fixing slots are opened on the inner wall of the take-up reel. The fixing block extends into the fixing slot and is slidably connected to the side wall of the fixing slot. The positioning mechanism is disposed on the main shaft and is used to position the take-up reel and the main shaft.

[0008] Furthermore, the positioning mechanism includes a positioning ring, a positioning groove, a positioning block, and a synchronous rotation mechanism. The positioning ring is fixedly disposed on the side wall of the main shaft. The side wall of the main shaft is provided with a plurality of positioning grooves. A first gear is rotatably disposed in the positioning groove. The positioning block is fixedly disposed on the side wall of the first gear.

[0009] Furthermore, the synchronous rotation mechanism includes a first cavity, a moving block, and a moving mechanism. The first cavity is opened inside the main shaft. The moving block is slidably disposed inside the first cavity. A first rack is fixedly disposed on the side wall of the moving block near the first gear. The first rack meshes with the adjacent first gear. The moving mechanism is disposed on the moving block and is used to drive the moving block to move within the first cavity.

[0010] Furthermore, the moving mechanism includes an adjusting groove, a threaded rod, a handwheel, and a limiting mechanism. The adjusting groove is formed on the side wall of the first cavity, and a first housing is rotatably disposed within the adjusting groove. The threaded rod is rotatably disposed between the first housing and the side wall of the first cavity. The handwheel is rotatably disposed on the main shaft and is fixedly connected to the threaded rod. The limiting mechanism is disposed on the first housing and is used to limit the rotation angle of the first housing.

[0011] Based on the above scheme, the limiting mechanism includes an annular groove, a limiting through groove, a limiting groove, a limiting disc, and a pressing mechanism. The annular groove is formed on the side wall of the adjusting groove, the limiting through groove is formed on the side wall of the adjusting groove, the limiting through groove communicates with the annular groove, the limiting groove is formed on the side wall of the first cavity, the limiting disc is slidably disposed in the first housing, a limiting block is fixedly disposed on the side wall of the limiting disc, the limiting block extends through the limiting groove into the limiting through groove, and the pressing mechanism is disposed on the handwheel for driving the limiting disc to move within the first housing.

[0012] Based on the above scheme, the pressing mechanism includes a pressing groove and a pressing plate. The pressing groove is formed on the handwheel, and a pressing port is formed at the bottom of the pressing groove. The pressing port is connected to the first housing. The pressing plate is slidably disposed in the pressing groove, and a pressing rod is fixedly disposed between the pressing plate and the limiting plate.

[0013] Based on the above scheme, a support spring is fitted on the pressing rod, and the two ends of the support spring are fixedly connected to the pressing plate and the bottom of the pressing groove, respectively.

[0014] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, by setting up a fixing mechanism, after the take-up reel is mounted on the main shaft, the fixing block can be inserted into the fixing through groove. Then, by rotating the handwheel, the threaded rod can be rotated. In turn, the threaded rod and the moving block are moved by the threaded engagement of the threaded rod and the moving block. Thus, the first gear is rotated by the meshing of the first rack and the first gear, and the positioning block is pressed against the surface of the take-up reel, thereby facilitating the fixing between the main shaft and the take-up reel. 2. In this utility model, by setting a limiting mechanism, after the take-up reel is fixed, the pressing plate, pressing rod and limiting plate can be moved by the elastic force of the support spring. At the same time, the limiting plate drives the limiting block to extend into the limiting through groove. Then, the limiting block and the limiting through groove cooperate to limit the first housing and the threaded rod, thereby avoiding the impact on the installation stability of the take-up reel due to the rotation of the threaded rod.

[0023] like Figures 1-6 As shown, a frame-type stranding machine for cable processing according to an embodiment of the present invention is illustrated. It includes a base plate 1, a stranding machine body 2, a support frame 3, a main shaft 4, a first motor 5, a take-up reel 6, and a fixing mechanism. The stranding machine body 2 is mounted on the base plate 1, the support frame 3 is fixedly mounted on the base plate 1, the main shaft 4 is rotatably mounted on the side wall of the support frame 3, the first motor 5 is mounted on the support frame 3, and the output end of the first motor 5 is fixedly connected to the main shaft 4. The take-up reel 6 is fitted onto the main shaft 4, and the fixing mechanism is disposed between the main shaft 4 and the take-up reel 6 for fixing the main shaft 4 and the take-up reel 6.

[0024] Reference Figures 1-3 The fixing mechanism includes a fixing block 7, a fixing slot 8, and a positioning mechanism. Multiple fixing blocks 7 are fixedly installed on the side wall of the main shaft 4, and multiple fixing slots 8 are opened on the inner wall of the take-up reel 6. The fixing blocks 7 extend into the fixing slots 8 and are slidably connected to the side wall of the fixing slots 8. The positioning mechanism is installed on the main shaft 4 and is used to position the take-up reel 6 and the main shaft 4. Specifically, after the take-up reel 6 is installed on the main shaft 4, the fixing blocks 7 can extend into the fixing slots 8. During the rotation of the main shaft 4, the take-up reel 6 can be driven to rotate through the cooperation of the fixing blocks 7 and the fixing slots 8.

[0025] Reference Figures 2-5The positioning mechanism includes a positioning ring 9, a positioning groove 10, a positioning block 12, and a synchronous rotation mechanism. The positioning ring 9 is fixedly mounted on the side wall of the main shaft 4. Multiple positioning grooves 10 are formed on the side wall of the main shaft 4. A first gear 11 is rotatably mounted within each positioning groove 10. The positioning block 12 is fixedly mounted on the side wall of the first gear 11. The synchronous rotation mechanism is located within the main shaft 4 and is used to drive the multiple first gears 11 to rotate synchronously. The synchronous rotation mechanism includes a first cavity 13, a moving block 14, and a moving mechanism. The first cavity 13 is located within the main shaft 4. The moving block 14 is slidably mounted within the first cavity 13. A first rack 15 is fixedly mounted on the side wall of the moving block 14 closest to the first gear 11. The first rack 15 meshes with the adjacent first gear 11. The moving mechanism is mounted on the moving block 14 and is used to drive the moving block 14 to move within the first cavity 13. The moving mechanism includes an adjusting groove, a threaded rod 16, a handwheel 17, and a limiting mechanism. The adjusting groove is opened on the side wall of the first cavity 13, and the first housing is rotatably disposed in the adjusting groove. The threaded rod 16 is rotatably disposed between the first housing and the side wall of the first cavity 13. The handwheel 17 is rotatably disposed on the main shaft 4 and is fixedly connected to the threaded rod 16. The limiting mechanism is disposed on the first housing and is used to limit the rotation angle of the first housing. Specifically, the rotation of the handwheel 17 can drive the threaded rod 16 to rotate, and then the threaded engagement between the threaded rod 16 and the moving block 14 can drive the moving block 14 and the first rack 15 to move. Thus, the meshing of the first rack 15 and the first gear 11 can drive the first gear 11 to rotate and drive the positioning block 12 to press against the surface of the take-up reel 6, thereby facilitating the fixation between the main shaft 4 and the take-up reel 6.

[0026] Reference Figures 4-6The limiting mechanism includes an annular groove 18, a limiting through groove 19, a limiting groove 20, a limiting plate 21, and a pressing mechanism. The annular groove 18 is formed on the side wall of the adjusting groove, and the limiting through groove 19 is formed on the side wall of the adjusting groove, communicating with the annular groove 18. The limiting groove 20 is formed on the side wall of the first cavity 13. The limiting plate 21 is slidably disposed within the first housing. A limiting block 22 is fixedly disposed on the side wall of the limiting plate 21, extending through the limiting groove 20 and into the limiting through groove 19. The pressing mechanism is disposed on the handwheel 17 and is used to drive the limiting plate 21 to move within the first housing. The pressing mechanism includes a pressing groove 23 and a pressing plate 24. The pressing groove 23 is formed on the handwheel 17, and a pressing port is formed at the bottom of the pressing groove 23 for pressing. The opening is connected to the first housing. The pressing plate 24 is slidably disposed in the pressing groove 23. A pressing rod 25 is fixedly disposed between the pressing plate 24 and the limiting plate 21. A support spring 26 is fitted on the pressing rod 25. The two ends of the support spring 26 are fixedly connected to the pressing plate 24 and the bottom of the pressing groove 23, respectively. Specifically, after the take-up reel 6 is fixed, the pressing plate 24, the pressing rod 25 and the limiting plate 21 can be moved by the elastic force of the support spring 26. At the same time, the limiting plate 21 drives the limiting block 22 to extend into the limiting through groove 19. Then, the limiting block 22 and the limiting through groove 19 cooperate to limit the first housing and the threaded rod 16, thereby avoiding the impact on the installation stability of the take-up reel 6 due to the rotation of the threaded rod 16.

[0027] In this embodiment, during use, after the operator mounts the take-up reel 6 onto the main shaft 4, the fixing block 7 can extend into the fixing through groove 8. Then, the operator pushes the pressing plate 24, which in turn moves the limiting plate 21 and the limiting block 22 via the pressing rod 25, causing the limiting block 22 to extend into the annular groove 18. The operator then rotates the handwheel 17, which drives the threaded rod 16 to rotate. The threaded engagement between the threaded rod 16 and the moving block 14 moves the moving block 14 and the first rack 15. This allows the first rack 15 to mesh with the first gear 11, causing the first gear 11 to rotate. The positioning block 12 is pressed against the surface of the take-up reel 6, which facilitates the fixation between the main shaft 4 and the take-up reel 6. After that, the operator releases the pressing plate 24, and the pressing plate 24, pressing rod 25 and limiting plate 21 are moved by the elastic force of the support spring 26. At the same time, the limiting plate 21 drives the limiting block 22 to extend into the limiting through groove 19. Then, the cooperation between the limiting block 22 and the limiting through groove 19 realizes the limiting of the first housing and the threaded rod 16, thereby preventing the rotation of the threaded rod 16 from affecting the installation stability of the take-up reel 6. After that, the pressing plate 24 is pushed and the handwheel 17 is turned to disassemble the take-up 6, which makes it easy to replace.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
