Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an automatic cable winding and unwinding device. Background Technology

[0002] A cable is a conductor made of one or more insulated conductors and an outer insulating protective layer, used to transmit electricity or information from one place to another. Another definition is that a cable is usually made of several or groups of conductors (at least two conductors per group) twisted together, with each group of conductors insulated from each other and often twisted around a central core, with the entire outer layer covered by a highly insulating material.

[0003] As described in announcement number CN221916863U, an automatic cable winding and unwinding device includes a base platform. Symmetrically mounted support seats are mounted on the top of the base platform. A winding shaft is movably mounted on the inner side of each of the two sets of support seats, and a winding drum is mounted on the outer side of the winding shaft. A clamping assembly is symmetrically mounted on the top of the base platform. This clamping assembly is used to clamp the cable wound around the outside of the winding drum, preventing the cable from loosening during winding. In this invention, when winding the cable, the cable on the winding drum exerts a squeezing effect on the clamping roller, causing the guide rod to slide inwards into the limiting sleeve. The telescopic spring is compressed, and the rebound force generated by the compressed telescopic spring can be applied to the cable being wound through the clamping roller, clamping the cable on the winding drum and preventing the cable from loosening during winding.

[0004] This application uses a telescopic spring to prevent cable loosening during winding. However, during long-term use, the frequent extension and retraction of the telescopic spring can lead to fatigue and wear of the spring material. This fatigue and wear will gradually reduce the spring's elasticity and restoring force, thus affecting its anti-loosening effect.

[0005] Therefore, we propose a novel automatic cable reeling and unloading device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in the prior art, during long-term use of telescopic springs, frequent extension and retraction movements lead to fatigue and wear of the spring material. This fatigue and wear gradually reduces the elasticity and restoring force of the spring, thereby affecting its anti-loosening effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an automatic cable winding and unwinding device, comprising a base platform, a winding drum disposed on the top surface of the base platform, an anti-loosening component connected inside the base platform, the anti-loosening component comprising a connecting rod, one end of the connecting rod being connected to the output end of a motor, two sets of first gears being connected to the surface of the connecting rod, support frames being connected to the surfaces of the base platform near the two sets of first gears, bearing sleeves disposed inside the support frames, one-way screws inserted inside the bearing sleeves, a second gear being connected to the bottom of the one-way screws, a lifting frame being connected to the surface of the one-way screws, threaded holes being opened inside the lifting frame, pressure sensors being connected to the top of the lifting frame, and anti-loosening top plates being connected to the tops of the two sets of pressure sensors.

[0008] Furthermore, guide sleeves are connected to the four bottom corners of the anti-loosening top plate, and guide posts are connected to the four corners of the surface of the base platform.

[0009] Furthermore, the outer surface of the guide post is in contact with the inner wall of the guide sleeve, and a sliding connection is formed between the guide post and the guide sleeve. A PLC controller is connected to one side of the front end of the base.

[0010] Furthermore, the PLC controller is electrically connected to an external power supply via a control switch, and is also electrically connected to both sets of pressure sensors and the motor.

[0011] Furthermore, the position and size of the first gear match the position and size of the second gear, and the first gear and the second gear form a meshing connection.

[0012] Furthermore, the one-way screw and the bearing sleeve form a rotatable connection, and the one-way screw and the lifting frame form a threaded connection through a threaded hole.

[0013] Furthermore, a wire feeding assembly is connected to the center of the front surface of the base platform. The wire feeding assembly includes a fixing frame, and a threaded rod is inserted into the top of the fixing frame.

[0014] Furthermore, a throttle is connected to the top of the threaded rod, a bearing body is connected to the bottom of the threaded rod, and a limit block is connected to the bottom of the bearing body.

[0015] Furthermore, the inner walls on both sides of the fixing frame are provided with sliding grooves, the two sides of the limiting block are connected with sliders, and the bottom surface of the base is provided with grooves.

[0016] Furthermore, the threaded rod and the fixed frame form a threaded connection, the threaded rod and the bearing body form a rotatable connection, and the limiting block forms a sliding connection with the slider and the slide groove.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] In this invention, the pressure value sensed by the pressure sensor can be sent to the PLC controller, which can then use a gear meshing connection to automatically adjust the lifting of the anti-loosening top plate. This ensures that the cable tension is optimal during the winding process, avoiding the problem of springs loosening over time and affecting the anti-loosening effect.

[0019] In this invention, the height of the limiting block can be adjusted by rotating the handle, thereby ensuring that the cable can be stably clamped during the cable laying process and avoiding problems such as unstable clamping or falling off due to cable size mismatch.

[0027] 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.

[0028] 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.

[0029] Example 1, as Figure 1 - Figure 5 As shown, this utility model provides an automatic cable winding and unwinding device, including a base platform 1. A winding drum 2 is provided on the top surface of the base platform 1. An anti-loosening component 3 is connected inside the base platform 1. The anti-loosening component 3 includes a connecting rod 301. One end of the connecting rod 301 is connected to the output end of a motor 302. Two sets of first gears 303 are connected to the surface of the connecting rod 301. Support frames 304 are connected to the surfaces of the base platform 1 near the two sets of first gears 303. A bearing sleeve 305 is provided inside the support frame 304. A one-way screw 306 is inserted into the bearing sleeve 305. A second gear 307 is connected to the bottom of the one-way screw 306. A lifting frame 308 is connected to the surface of the one-way screw 306. A threaded hole 309 is opened inside the lifting frame 308. A pressure sensor 310 is connected to the top of the lifting frame 308. An anti-loosening top plate is connected to the top of the two sets of pressure sensors 310. 311, guide sleeves 312 are connected to the four corners of the bottom of the anti-loosening top plate 311, and guide posts 313 are connected to the four corners of the surface of the base platform 1. The outer surface of the guide post 313 is in contact with the inner wall of the guide sleeve 312, and a sliding connection is formed between the guide post 313 and the guide sleeve 312. A PLC controller 314 is connected to one side of the front end of the base platform 1. The PLC controller 314 is electrically connected to an external power supply through a control switch. The PLC controller 314 is electrically connected to two sets of pressure sensors 310 and the motor 302. The position and size of the first gear 303 match the position and size of the second gear 307. The first gear 303 and the second gear 307 form a meshing connection. A one-way screw 306 is rotatably connected to the bearing sleeve 305. The one-way screw 306 is threadedly connected to the lifting frame 308 through the threaded hole 309.

[0030] The overall effect of Embodiment 1 is that, during cable winding, the anti-loosening top plate 311 can prevent the cable from loosening during winding. When the pressure sensor 310 is under high pressure, it sends a group A electrical signal to the PLC controller 314, enabling the PLC controller 314 to start the forward rotation function of the motor 302. When the output end of the motor 302 rotates forward, it can drive the connecting rod 301 to rotate forward, thereby causing the two sets of first gears 303 to rotate forward simultaneously. When the two sets of first gears 303 rotate forward, they will mesh with the two sets of second gears 307 in the forward direction, thereby driving the two sets of one-way screws 306 to rotate forward simultaneously. When the one-way screws 306 rotate forward, they will also rotate with the lifting frame 308 through the threaded hole 309, so that the lifting frame 308 can rotate in the threaded direction to push the pressure sensor 310 to activate the anti-loosening mechanism. The top plate 311 moves downwards. When the anti-loosening top plate 311 moves downwards, it also drives the guide column 313 to slide within the guide sleeve 312, improving the stability of the anti-loosening top plate 311 when it moves downwards. When the pressure sensor 310 is within the normal range, the motor 302 will automatically shut off. When the pressure on the anti-loosening top plate 311 is low, the pressure sensor 310 will send a B group signal to the PLC controller 314, which will enable the PLC controller 314 to control the output end of the motor 302 to rotate in the opposite direction. This will cause the two sets of one-way screws 306 to rotate in the opposite direction at the same time, thereby causing the two sets of support frames 304 to drive the anti-loosening top plate 311 to move upwards, preventing the cable from loosening during winding and ensuring that the cable tension reaches the optimal state during winding. This avoids the problem that the spring may loosen after long-term use, thus affecting the anti-loosening effect.

[0031] Example 2, as Figure 1 and Figure 6 As shown, a wire feeding assembly 4 is connected to the center of the front surface of the base 1. The wire feeding assembly 4 includes a fixing frame 401. A threaded rod 402 is inserted into the top of the fixing frame 401. A throttle 403 is connected to the top of the threaded rod 402. A bearing body 404 is connected to the bottom of the threaded rod 402. A limit block 405 is connected to the bottom of the bearing body 404. Slide grooves 407 are provided on both sides of the inner wall of the fixing frame 401. Slider blocks 406 are connected to both sides of the limit block 405. A groove 408 is provided on the bottom surface of the base 1. The threaded rod 402 and the fixing frame 401 are connected by a thread. The threaded rod 402 and the bearing body 404 are connected by a rotation. The limit block 405 is connected to the slide groove 407 through the slider 406.

[0032] The effect achieved by the entire embodiment 2 is that when the cable is laid out, the threaded rod 402 and the fixing frame 401 can be rotated by rotating the throttle 403, so that the threaded rod 402 can push the limiting block 405 downward through the bearing body 404 to realize the compression and fixation of the cable. When the limiting block 405 moves downward, it will also drive the slider 406 to slide in the slide groove 407, which improves the stability of the limiting block 405 when it is raised and lowered, and avoids the problem of unstable clamping or falling off due to cable size mismatch.

[0033] Working principle: The pressure value sensed by the pressure sensor 310 can be sent to the PLC controller 314, which can drive the anti-loosening top plate 311 to automatically adjust its height through gear meshing. This ensures that the tension of the cable is at its optimal state during the winding process, avoiding the problem of springs loosening after long-term use and affecting the anti-loosening effect. Furthermore, the height of the limit block 405 can be adjusted by rotating the throttle 403, thereby ensuring that the cable can be stably clamped during the unwinding process and avoiding problems such as unstable clamping or falling off due to cable size mismatch.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
