Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 , Attachment Figure 2 and attached Figure 3The utility model provides an embodiment of an adjustable cable reel, comprising a left baffle 1, the middle part of the left baffle 1 is rotatably connected to a screw rod 3, the other end of the screw rod 3 is rotatably connected to the right baffle 4, the outer wall of the screw rod 3 is threadedly connected to a threaded sleeve 5, the outer wall of the threaded sleeve 5 is fixedly connected to a plurality of fixing blocks 10, the outer wall of the fixing block 10 is rotatably connected to a support rod 6, the other end of the support rod 6 is rotatably connected to a fixing block 2 11, the other end of the fixing block 2 11 is fixedly connected to a fan-shaped plate 7, the outer walls of the adjacent sides of the left baffle 1 and the right baffle 4 are provided with a slide groove 8, the two ends of the fan-shaped plate 7 are slidably connected to the inner wall of the slide groove 8, the outer walls of the left baffle 1 and the right baffle 4 away from the side are fixedly connected to a flange 9, the outer wall of the flange 9 is provided with an automatic bracket 2, and the automatic bracket 2 is used for automatically retracting and releasing the cable;

[0033] Specifically, the screw rod 3 can rotate stably under the support of the left baffle 1. The other end of the screw rod 3 is rotatably connected to the right baffle 4. The right baffle 4 cooperates with the left baffle 1 to provide support and fixation for the screw rod 3 and other related components. The threaded sleeve 5 can move axially according to the rotation direction of the screw rod 3. This threaded connection method enables the threaded sleeve 5 to achieve precise position adjustment under the drive of the screw rod 3. The outer wall of the fixed block 10 is rotatably connected to the support rod 6. The rotational connection method of the support rod 6 and the fixed block 10 enables the support rod 6 to flexibly adjust the angle under the drive of the fixed block 10, thereby pushing or pulling the fan-shaped plate 7. The rotational connection between the support rod 6 and the fixed block 2 11 ensures that when the support rod 6 moves, it can smoothly drive the fan-shaped plate 7 to perform corresponding movements. The slide 8 provides a sliding track for the two ends of the fan-shaped plate 7, allowing the fan-shaped plate 7 to slide smoothly along a specific direction under the action of the support rod 6. The flange 9, as a key part connecting other components, provides a foundation for the installation and fixation of the automatic bracket 2.

[0034] Please see the attached Figure 4 and attached Figure 5 The automatic bracket 2 includes a lower tile 202, the top surface of the lower tile 202 is rotatably connected to the outer wall of the flange 9, the top surface of the lower tile 202 is fixedly connected to the upper tile 201, the bottom surface of the lower tile 202 is fixedly connected to the right support leg 207, the bottom surface of the right support leg 207 is fixedly connected to the servo motor 205, the output end of the servo motor 205 is fixedly connected to the reducer 206, one end of the flange 9 and the other end of the reducer 206 are fixedly connected to the pulley 203, and the two pulleys 203 are rotatably connected through a transmission belt 204;

[0035] Specifically, the top surface of the lower tile 202 is rotationally connected with the outer wall of the flange plate 9, and this connection mode enables the relative flexible rotation between the two, thereby providing a basic condition for subsequent operation. The upper tile 201 cooperates with the lower tile 202 to jointly form a relatively stable structure, thereby providing a solid support for the installation and operation of the flange plate 9. The right supporting leg 207 plays a supporting and stabilizing role to ensure that the device can remain stable during operation. The servo motor 205 serves as the power source of the automatic support 2 and can provide accurate power output to provide power support for the operation of the entire system. The function of the speed reducer 206 is to reduce the output speed of the servo motor 205 while increasing the output torque, so that the device can operate at a more stable and appropriate speed. The flange plate 9 has one end fixedly connected with a belt pulley 203, and the other end of the speed reducer 206 is also fixedly connected with a belt pulley 203. The belt pulley 203 enables power to be transmitted through a transmission belt 204, thereby achieving power transmission between different components.

[0036] Please refer to the accompanying Figure 1 and the accompanying Figure 4 The outer wall of the left flange plate 9 is rotationally connected with a rotating piece 22. The bottom of the rotating piece 22 is fixedly connected with a left supporting leg 21. The outer wall of the left supporting leg 21 is threadedly connected with a cross beam 12. The other end of the cross beam 12 is threadedly connected with the outer wall of the left supporting leg 21. The middle of the upper tile 201 is threadedly connected with a locking screw 17. The top surface of the right supporting leg 207 is fixedly connected with a protective shell 16. The left end of the lead screw 3 is fixedly connected with a hexagonal prism 20. The outer wall of the left baffle 1 is provided with a wire clamping hole 18. The top surface of the right supporting leg 207 is fixedly connected with an operation table 14. The top surface of the operation table 14 is fixedly connected with a controller 15. The outer wall of the left supporting leg 21 is fixedly connected with a reinforcing rib 13. The bottom surface of the left supporting leg 21 is provided with a mounting hole 19.

[0037] Specifically, the outer wall of the flange plate 9 on the left is rotationally connected with a rotating piece 22. The rotating piece 22 plays a role of connection and rotation here. The left supporting leg 21 serves as a part of the supporting structure and provides stable support for the entire device. The cross beam 12 plays a role of connection and strengthening of the structural stability in the entire device. The threaded connection of the cross beam 12 with the left supporting leg 21 makes the installation and disassembly of the cross beam 12 more convenient, and also enables the length to be adjusted according to actual needs to adapt to different installation environments and use requirements. The locking screw 17 plays a role of fixing and locking the winding drum. The hexagonal prism 20 facilitates the rotation operation of the lead screw 3. The lead screw 3 can be easily rotated through the cooperation of a tool and the hexagonal prism 20, thereby achieving adjustment and control of the entire device. The controller 15 is the core control component of the entire device. Through the control of the servo motor 205 and the speed reducer 206, automatic winding and unwinding operation of the cable drum is realized. The mounting hole 19 is used to fix the device on the installation base. The servo motor 205 is of Mitsubishi HG-KR23J type, and the controller 15 is of EPC-A10 type.

[0038] Working principle: When the reel diameter needs to be adjusted, the hexagonal prism 20 is rotated, the screw rod 3 is rotated, the threaded sleeve 5 is threadedly connected to the screw rod 3, the threaded sleeve 5 moves in the right direction, the support rod 6 is rotatably connected to the threaded sleeve 5 and the fan plate 7, the fan plate 7 is restricted between the left baffle 1 and the right baffle 4, and multiple fan plates 7 move along the corresponding slide grooves 8 to change the reel diameter. The outer diameter of the reel is adjusted by changing the radial position of the fan plate 7 to adapt to the winding of cables of different diameters. When a thicker cable needs to be wound, the outer diameter of the reel is increased, so that the bending radius of the cable during winding is increased and the bending stress of the cable is reduced. When a thinner cable is wound, the outer diameter of the reel is reduced to save space and keep the cable tightly wound.

[0039] When the cable needs to be wound, one end of the cable is inserted into the wire clamping hole 18, and the servo motor 205 is started. The rotational power of the servo motor 205 increases the torque and reduces the speed through the reducer 206, and is then transmitted to the flange 9 through the pulley 203 and the transmission belt 204. The flange 9 is fixedly connected to the right baffle 4, and the flange 9 is rotationally connected to the upper tile 201 and the lower tile 202. The reel rotates and starts to wind the cable. No manual intervention is required, which greatly saves operation time.
