Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable winding device. Background Technology

[0002] Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc., used to connect circuits, electrical appliances, etc. Cables need to be wound up according to actual use.

[0003] A search revealed that Chinese patent CN221500152U discloses a cable winding device. This cable winding device, through the arrangement of a support shaft, spring, support block, connecting block and roller, uses the spring force to make the roller press against the cable. When the drive motor drives the winding drum to rotate and wind the cable, the roller can make the cable wind more tightly, making it less likely for the cable to fall off the winding drum, thus facilitating the storage and transportation of the cable.

[0004] Because the roller length in the above device is fixed, it cannot be adapted to different specifications of cable reels, resulting in poor versatility. Furthermore, after the cable reel is wound and packaged, the spring is compressed to a certain extent due to the thickness of the cable reel, causing the roller to exert continuous pressure on the cable reel, making it difficult to remove when taking it out. Therefore, we propose a cable winding device. Utility Model Content

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figures 1 to 5 As shown, a cable winding device includes: a mounting frame 1, a drive motor 12 fixedly mounted on the rear side of the mounting frame 1 by bolts, the output shaft of the drive motor 12 passing through the mounting frame 1 and fixedly connected to a winding drum 13 via a rotating shaft, a fixing block 14 movably connected to the outer side of the winding drum 13, a mounting block 2 located not far from the top of the rear side of the winding drum 13, a sliding groove 25 formed at the front end of the mounting block 2, a knob 21 located at the top of the mounting block 2, a worm gear 22 fixedly connected to the knob 21 passing through the mounting block 2, a sector gear 23 in frictional contact at the front side of the worm gear 22, a fixing shaft 24 passing through the center of the sector gear 23, a connecting rod 231 fixedly connected to the front end of the sector gear 23, and a first fastening nut 31 passing through the front end of the connecting rod 231. The connecting rod 231 is rotatably connected to a U-shaped block 3 via a first fastening nut 31. A spring 32 is fixedly connected to the bottom end of the U-shaped block 3. An arc-shaped block 33 is fixedly connected to the bottom end of the spring 32. A slide rail 332 is provided on the left bottom end of the arc-shaped block 33. Protrusions 331 are provided on the left and right sides of the slide rail 332. A first mounting groove 333 is provided on the right bottom end of the arc-shaped block 33. A first rotating roller 334 is installed inside the first mounting groove 333. An extension plate 34 is in frictional contact inside the slide rail 332. Grooves 341 are provided on the left and right sides of the extension plate 34. A second mounting groove 342 is provided at the bottom of the extension plate 34. A second rotating roller 343 is installed inside the second mounting groove 342. A second fastening nut 35 passes through the left side of the arc-shaped block 33.

[0028] In this implementation scheme: the start-up drive motor 12 can drive the winding drum 13 to rotate through the rotating shaft to wind the cable. The fixing block 14 serves to fix the winding drum 13 of different specifications. The height of the connecting rod 231 can be adjusted by rotating the knob 21 to drive the internal gear structure to adapt to the height of the cable roll. The included angle is fixed by the first fastening nut 31 to keep the U-shaped block 3 in a vertical state. The extension plate 34 can adjust the overall length of the arc-shaped block 33 and is fixed by the second fastening nut 35.

[0029] like Figures 1 to 2 As shown, the worm gear 22 meshes with the sector gear 23, and the knob 21 forms a linkage structure with the sector gear 23 through the worm gear 22.

[0030] In this implementation scheme: rotating the knob 21 drives the worm gear 22 to rotate, which in turn drives the sector gear 23 to swing up and down, thereby adjusting the height of the connecting rod 231.

[0031] like Figure 2 As shown, the left and right ends of the fixed shaft 24 are fixedly connected to the mounting block 2, and the sector gear 23 is rotatably connected to the fixed shaft 24.

[0032] In this embodiment: the fixed shaft 24 is fixed inside the mounting block 2 to provide stability, so that the sector gear 23 rotates around the fixed shaft 24 under the drive of the worm gear 22.

[0033] like Figures 1 to 2 As shown, the outer diameter of the connecting rod 231 is the same as the inner diameter of the slide groove 25, and the connecting rod 231 is slidably connected to the slide groove 25.

[0034] In this embodiment, the connecting rod 231 slides inside the slide groove 25 and maintains stable oscillation under the constraint of the slide groove 25.

[0035] like Figures 1 to 3 As shown, the U-shaped block 3 is elastically connected to the arc-shaped block 33 by the spring 32.

[0036] In this implementation plan: during the cable winding process, the height of the cable roll continuously increases, causing the arc-shaped block 33 to rise upwards, and the spring 32 plays the role of adjusting the height.

[0037] like Figures 3 to 5 As shown, the outer diameter of the extension plate 34 is the same as the inner diameter of the slide rail 332, and the extension plate 34 is slidably connected to the slide rail 332. The protrusion 331 and the groove 341 are positioned corresponding to each other.

[0038] In this embodiment: the extension plate 34 slides inside the slide rail 332, which serves to adjust the length of the arc block 33 to accommodate different specifications of winding spools 13. The protrusion 331 engages with the groove 341 to provide a stable connection.

[0039] like Figures 3 to 5 As shown, the first rotating roller 334 is rotatably connected to the first mounting groove 333, and the second rotating roller 343 is rotatably connected to the second mounting groove 342. The second rotating roller 343 and the first rotating roller 334 are symmetrically arranged about the central axis of the arc-shaped block 33.

[0040] In this implementation scheme: the front and rear ends of the first roller 334 are fixed inside the first mounting groove 333 by a rotating shaft and rotate inside. The front and rear ends of the second roller 343 are fixed inside the second mounting groove 342 by a rotating shaft and rotate inside. The second roller 343 is symmetrical to the first roller 334 and performs the winding operation of the cable, so that the cable is not easy to loosen.

[0041] Working principle: When using this cable winding device, the operator installs the winding drum 13 on the rotating shaft and fixes it with the fixing block 14. One end of the cable is inserted into the slot on the winding drum 13. Then, the knob 21 is rotated to drive the internal gear structure to adjust the connecting rod 231 so that the first rotating roller 334 and the second rotating roller 343 are in contact with the winding drum 13, and the U-shaped block 3 is kept perpendicular. Then, the U-shaped block 3 is fixed with the first fastening nut 31. Next, the second fastening nut 35 is loosened, and the extension plate 34 is pulled out to the same size as the winding drum 13 and fixed with the second fastening nut 35. Finally, the drive motor 12 is started. The drive motor 12 drives the cable to rotate along the winding drum 13 to perform the winding work. The elasticity of the spring 32 makes the two sets of rotating rollers press against the cable, making the cable winding tighter. After winding is completed, the first fastening nut 31 is loosened first, and then the overall height of the device is raised by the knob 21, so that the pressure of the roller on the cable roll is automatically released, and the cable roll can be easily picked up and put away.

[0042] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
