Description

Technical Field

[0001] This utility model relates to the field of cable turntable technology, specifically a cable take-up and untake-down turntable. Background Technology

[0002] Cables are generally made of one or more mutually insulated conductors covered with insulation and protective layers. Their function is to transmit electricity or information from one place to another. Cables are an indispensable device in the field of electronic power in modern society. After the cables are processed, in order to facilitate transportation, they are usually wound around on cable winding reels, bundled and then sold. With the development of science, there are more and more cable winding reels.

[0003] However, in actual use, the inner diameter of the internal winding of a traditional cable winding turntable cannot be changed. That is, the winding roller of the cable winding turntable cannot be made to change diameter. As a result, it can only complete the winding of a single inner diameter when winding, which cannot meet the usage requirements of winding with different inner diameters and has certain limitations. Therefore, this utility model proposes a cable winding turntable with dynamic adjustment of inner diameter. Utility Model Content

[0004] The purpose of this invention is to provide a cable take-up and take-down turntable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable winding turntable, comprising a first turntable side plate and a second turntable side plate, wherein the first turntable side plate and the second turntable side plate are arranged in a mirror symmetrical manner, and each of the first turntable side plate and the second turntable side plate is provided with five guide grooves. The five guide grooves on the same turntable are circumferentially distributed at equal intervals through the center point of the turntable. A threaded screw is rotatably installed in the guide groove of the first turntable side plate through a bearing. Each threaded screw is threadedly connected to a threaded seat. The top end of the threaded screw is fixedly connected to the output shaft of a servo motor. The servo motor is fixedly installed on the top outer wall of the first turntable side plate. A variable diameter plate is fixedly installed on the outside of each threaded seat. The outer surface of the variable diameter plate adopts an arc-shaped structure design.

[0006] Preferably, a sliding light rod is fixedly installed in the guide groove of the side plate of the second turntable, and a sliding seat is slidably connected to each sliding light rod.

[0008] Preferably, guide rails are fixedly installed on both sides of the guide groove of the first turntable side plate and the second turntable side plate.

[0009] Preferably, the guide rails are in a limiting sliding connection with the corresponding threaded seat and sliding seat.

[0010] Preferably, a rotating shaft is fixedly installed at the center of the outer surface of both the first turntable side plate and the second turntable side plate, and a drive gear is fixedly installed on the outer wall of the rotating shaft of the second turntable side plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a threaded drive to drive a variable diameter plate to freely contract inward and expand outward. In practical use, the inner diameter of the take-up and unwinding turntable can be freely changed, providing a dynamic adjustment effect for the inner diameter. The inner diameter can be dynamically adjusted according to actual take-up and unwinding requirements, thus adapting to different cable take-up and unwinding needs. Compared to traditional single, non-adjustable inner diameter turntables, this invention offers a dynamic adjustment effect for the inner diameter, making it suitable for a wider range of take-up and unwinding inner diameter requirements. This effectively improves the overall performance, reduces limitations, and broadens the application range, making it more practical. Attached Figure Description

[0022] Please see Figure 1-5 The present invention provides an embodiment of a cable winding turntable, comprising a first turntable side plate 1 and a second turntable side plate 2, wherein the first turntable side plate 1 and the second turntable side plate 2 are arranged in a mirror symmetrical manner.

[0023] For details, please refer to the appendix of the instruction manual. Figure 3 as well as Figure 4 As shown, in order to adjust the inner diameter and winding size of the turntable, five guide grooves 3 are provided on the first turntable side plate 1 and the second turntable side plate 2. The five guide grooves 3 on the same turntable are circumferentially distributed at equal intervals through the center point of the turntable. A threaded screw 4 is rotatably installed in the guide groove 3 of the first turntable side plate 1 through a bearing. Each threaded screw 4 is threadedly connected to a threaded seat 5. The top end of the threaded screw 4 is fixedly connected to the output shaft of a servo motor 6. Thus, the servo motor 6 can drive the threaded screw 4 to perform automatic forward and reverse rotation. The servo motor 6 is fixedly installed on the top outer wall of the first turntable side plate 1. A variable diameter plate 7 is fixedly installed on the outside of each threaded seat 5. The outer surface of the variable diameter plate 7 adopts an arc structure design.

[0024] Based on the above structure, when it is necessary to adjust the inner diameter of the cable winding turntable of this utility model, the servo motor 6 can rotate in the same direction in both forward and reverse directions. When several servo motors 6 rotate in the same direction, they will synchronously drive the threaded screw 4 to rotate. When the threaded screw 4 rotates in both directions under the drive of the servo motor 6, the threaded seat 5 connected to it can move linearly up and down along the threaded screw 4. In this way, the up and down displacement of the threaded seat 5 can drive the variable diameter plate 7 to perform synchronous displacement work.

[0025] Furthermore, when the servo motor 6 drives the threaded screw 4 to rotate forward, the threaded seat 5 on it moves from top to bottom. At this time, several variable diameter plates 7 gather inward, thereby reducing the inner diameter winding size of the turntable of this utility model.

[0026] When the servo motor 6 drives the threaded screw 4 to reverse, the threaded seat 5 on it moves from bottom to top. At this time, several variable diameter plates 7 expand outward, thereby increasing the inner diameter winding size of the turntable of this utility model.

[0027] This invention, through the combined use of the above-mentioned structures, allows the variable diameter plate 7 to be driven by a threaded drive to freely contract inward and expand outward. In actual use, the inner diameter of the take-up and unwinding turntable can be freely changed, providing a dynamic adjustment effect for the inner diameter. The inner diameter can be dynamically adjusted according to actual take-up and unwinding requirements, making it suitable for different cable take-up and unwinding needs. Compared to traditional single, non-adjustable inner diameter turntables, this invention has a dynamic adjustment effect for the inner diameter, making it suitable for more take-up and unwinding inner diameter requirements, effectively improving the overall performance, reducing limitations, and broadening its application range and practicality.

[0028] In this embodiment, in order to improve the connectivity and stability of the structure at the other end of the inner diameter plate 7, a sliding light rod 9 is fixedly installed in the guide groove 3 of the second turntable side plate 2, and a sliding seat 10 is slidably connected to each sliding light rod 9.

[0029] The end of the variable diameter plate 7 away from the threaded seat 5 is fixedly connected to the outer wall of the sliding seat 10;

[0030] The sliding seat 10 can be fixedly connected to the other end of the variable diameter plate 7, thereby improving the structural integrity of the other end of the variable diameter plate 7. The sliding seat 10 can slide freely under the action of the thread drive, thereby avoiding structural obstruction and having good displacement synchronization characteristics.

[0031] In this embodiment, in order to improve the linear displacement guidance of the threaded seat 5 and the sliding seat 10, guide rails 8 are fixedly installed on both sides of the guide groove 3 of the first turntable side plate 1 and the second turntable side plate 2. Several guide rails 8 are limited and slidably connected to the corresponding threaded seat 5 and sliding seat 10. Thus, the guide rails 8 can provide a certain displacement guidance for the displacement work between the threaded seat 5 and the sliding seat 10, and ensure the linear displacement effect of the seat body.

[0032] In this embodiment, in order to drive the turntable of this invention to rotate as a whole through an external structure, a rotating shaft is fixedly installed at the center of the outer surface of the first turntable side plate 1 and the second turntable side plate 2. A drive gear 11 is fixedly installed on the outer wall of the rotating shaft of the second turntable side plate 2. When in use, the drive gear 11 can mesh with the external drive motor and the gear structure. In this way, the external drive motor can drive the turntable of this invention to rotate as a whole through the transmission effect of the gear, thereby ensuring the normal rotation and loading / unloading effect of the turntable.

[0033] Working principle: When in use, the take-up and put-down turntable of this utility model can be installed on a suitable take-up and put-down frame and rotated and supported by the external take-up and put-down frame. When in use, the drive gear 11 can mesh with the external drive motor and gear structure. In this way, the external drive motor can drive the take-up and put-down turntable of this utility model to rotate as a whole through the transmission effect of the gear, thereby ensuring the normal rotation and take-up and put-down effect of the take-up and put-down turntable and ensuring normal use.

[0034] When it is necessary to adjust the inner diameter of the cable winding turntable of this utility model, the servo motor 6 can rotate in the same direction in both forward and reverse directions. When several servo motors 6 rotate in the same direction, they will drive the threaded screw 4 to rotate synchronously. When the threaded screw 4 rotates in both directions under the drive of the servo motor 6, the threaded seat 5 connected to it can move linearly up and down along the threaded screw 4. In this way, the up and down displacement of the threaded seat 5 can drive the variable diameter plate 7 to perform synchronous displacement work.

[0035] Furthermore, when the servo motor 6 drives the threaded screw 4 to rotate forward, the threaded seat 5 on it moves from top to bottom. At this time, several variable diameter plates 7 gather inward, thereby reducing the inner diameter winding size of the turntable of this utility model.

[0036] When the servo motor 6 drives the threaded screw 4 to reverse, the threaded seat 5 on it moves from bottom to top. At this time, several variable diameter plates 7 expand outward, thereby increasing the inner diameter winding size of the turntable of this utility model.

[0037] This invention, through the combined use of the above-mentioned structures, allows the variable diameter plate 7 to be driven by a threaded drive to freely contract inward and expand outward. In actual use, the inner diameter of the take-up and unwinding turntable can be freely changed, providing a dynamic adjustment effect for the inner diameter. The inner diameter can be dynamically adjusted according to actual take-up and unwinding requirements, making it suitable for different cable take-up and unwinding needs. Compared to traditional single, non-adjustable inner diameter turntables, this invention has a dynamic adjustment effect for the inner diameter, making it suitable for more take-up and unwinding inner diameter requirements, effectively improving the overall performance, reducing limitations, and broadening its application range and practicality.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
