Description

Technical Field

[0001] This invention relates to the field of cable routing technology, specifically to a cable winding and routing device. Background Technology

[0002] Cable winding and unwinding equipment generally consists of two parts: a winding device and a cable unwinding device. First, the cable is wound into the winding device, and then guided by the cable unwinding device, it is pushed out of the device. When operating indoors, workers can easily retrieve or replace the cable by simply stretching it to the appropriate length and then cutting it.

[0003] In current cable winding processes, a winding motor typically drives and controls the take-up reel to wind and collect the cable. A cable arrangement mechanism then sequentially positions the cable onto the take-up spool. When selecting a take-up spool, a longer spool is generally more suitable for thicker cables. This is because a longer spool provides a larger winding area, reducing cable overlap and crossing, which helps reduce mechanical stress and potential damage. Furthermore, a longer spool allows for better control of cable tension, ensuring stability and uniformity during winding. However, the selection of the spool length also needs to consider other factors, such as equipment space limitations, the total cable length, and the winding and unwinding speeds. If space is limited, a balance may need to be found between the spool length and safe cable winding. However, existing winding drums generally use a uniform length, which is basically impossible to extend or shorten, thus causing some trouble for the winding work.

[0004] Therefore, we propose a cable winding and unwinding device. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-11 The present invention provides a technical solution: a cable winding and unwinding device, comprising: Cable reel 10, the cable reel 10 being used to wind up cables; A base 11 is provided, on which a placement tray 12 is fixedly connected. The cable reel 10 is rotatably connected to the placement tray 12. Two sets of cables are symmetrically arranged on the base 11 about the vertical center of the cable reel 10. A pulley 14 is provided at the bottom of the base 11. The cable reel 10 can be extended to both sides in coordination with the base 11. The pulley 14 is rotatably connected to the base 11. The base 11 can be moved by rotating the base 11 in coordination with the pulley 14. Cable assembly 20, which is disposed on placement tray 12, is used to evenly arrange cables on cable reel 10; The reversing assembly 30 is used in conjunction with the cable laying assembly 20 to stack the cable on the cable reel 10. By cooperating with the cable laying assembly 20, the cable can be evenly wound on the cable reel 10. By cooperating with the reversing assembly 30 and the cable laying assembly 20, the cable can be stacked on the cable reel 10. By lengthening the cable reel 10, the winding area can be increased, thereby reducing the stacking and crossing of the cable. This helps to reduce the mechanical stress and potential damage to the cable.

[0024] The cable assembly 20 includes a lead screw 21, on which a cable winding assembly 22 is mounted. A sliding member 23 is located on one side of the lead screw 21, and a sliding member 24 is located on the other side. The lead screw 21 is slidably connected to both the sliding member 23 and the sliding member 24, which are both slidably connected to the placement tray 12. A driving assembly 25 is located on one side of the lead screw 21, and the driving assembly 25 is used to drive the lead screw 21 and the cable winding drum 1. The cable reel rotates, and the drive assembly 25 drives the cable reel 10 and the lead screw 21 to rotate. The cable winding assembly 22 moves along the direction of the lead screw 21, so that the cable reel 10 and the cable winding assembly 22 can evenly wind the cable onto the cable reel 10. The sliding parts 23 and 24 on both sides of the lead screw 21 can be lifted upwards when moving to the placement tray 12 with the reversing assembly 30, so as to stack the cable on the next layer of cable, thereby achieving the goal of evenly and layering the cable onto the cable reel 10.

[0025] The code assembly 22 includes a movable component 221, which is threadedly connected to a lead screw 21. A limiting block 222 is provided at the top of the movable component 221. A limiting rod 223 is provided between the sliding component 23 and the sliding component 24. The limiting block 222 and the limiting rod 223 are slidably connected. Under the restriction of the limiting block 222 and the limiting rod 223, the movable component 221 can move along the extension direction of the lead screw 21 when the lead screw 21 is rotated. A connector 224 is provided on one side of the movable component 221. Two connectors 224 are symmetrically arranged about the vertical center plane of the movable component 221. The cross-sectional shape of the connector 224 is an inner arc. A rotating rod 225 is rotatably connected inside the connector 224. The top of the rotating rod 225... A slider 226 is fixedly connected. A groove 229 is provided at the front end of the movable part 221. The slider 226 is slidably connected to the movable part 221. A knob 227 is threadedly connected to the top of the slider 226. The knob 227 can abut against the top of the movable part 221. By loosening the knob 227, the slider 226 can be moved within the movable part 221, thereby adjusting the distance between the connectors 224. Then, the cable is passed through the connectors 224, and by moving the slider 226, the connectors 224 clamp the cable, thereby achieving the limiting purpose. By tightening the knob 227, the slider 226 can be fixed. During the movement of the cable within the connectors 224, the connectors 224 can rotate on the rotating rod 225, thus not hindering the cable winding.

[0026] The bottom of the movable component 221 is provided with a lifting wheel 228. There are two lifting wheels 228 symmetrically arranged about the vertical center plane of the movable component 221. The lifting wheels 228 are rotatably connected to the movable component 221. When the movable component 221 moves to the placement tray 12, the reversing component 30 moves in the opposite direction in cooperation with the movable component 221. During the reversing process, the cable at the bottom of the movable component 221 is stacked on the lower layer cable. At this time, the lifting wheel 228 is lifted upward in contact with the cable, so as to continue to wind the cable on the lower layer cable.

[0027] The reversing assembly 30 includes a limiting assembly 31, which is disposed on one side of the lead screw 21. A switching assembly 32 is disposed on the other side of the lead screw 21. A buffer assembly 33 is disposed on the moving part 221. The limiting assembly 31 can limit the range of lateral movement of the lead screw 21. The lead screw 21, in conjunction with the buffer assembly 33 and the switching assembly 32, can switch the direction of rotation of the lead screw 21.

[0028] The limiting component 31 includes a limiting tube 311, which is fixedly connected to a sliding member 23. A lead screw 21 has two semi-circular grooves 312 inside the limiting tube 311. Limiting beads 313 are slidably connected within the semi-circular grooves 312. An abutment block 314 is connected to the top of each limiting bead 313. An abutment groove 315 is provided inside the limiting tube 311. The abutment block 314 is slidably connected to the limiting tube 311. A spring 316 is provided inside the abutment groove 315, with one end of the spring 316 fixedly connected to the abutment block 314. 6. The other end is fixedly connected to the limiting tube 311. When the buffer assembly 33 abuts against the placement plate 12, the lead screw 21 can be moved laterally, so that the limiting bead 313 can compress the spring 316 along the direction of the abutment groove 315. When the limiting bead 313 moves laterally into the semi-circular groove 312 on the other side, the lead screw 21 can rotate in the opposite direction with the switching assembly 32, so that the lead screw 21 drives the moving part 221 to move in the opposite direction. The limiting bead 313 can rotate in the abutment block 314. Thus, during the rotation of the lead screw 21, the limiting bead 313 does not affect the rotation of the lead screw 21.

[0029] The switching assembly 32 includes a switching housing 321, which is fixedly connected to a sliding member 24. A bevel gear 322 is rotatably connected to the bottom of the switching housing 321. Two bevel gears 322 are provided, each sleeved on the outside of a lead screw 21. A gear 323 is positioned between the bevel gears 322 and fixedly connected to the outer wall of the lead screw 21. The gear 323 has teeth on both sides. A gear 324 is fixedly connected to the bevel gear 322 and can mesh with the gear 323. A bevel gear 325 meshes with the bottom of the bevel gear 322. The second bevel gear 325 is rotatably connected to the switching housing 321. When the second bevel gear 325 rotates, the first bevel gear 322 meshing with it on both sides rotates along the center point of the first screw 21, and the first bevel gear 322 on both sides rotates in opposite directions. When the first screw 21, in conjunction with the buffer assembly 33 on the moving part 221, abuts against the placement plate 12 and moves laterally, the first gear 323 on the first screw 21 separates from the second gear 324 on one side of the first bevel gear 322 and meshes with the second gear 324 on the second bevel gear 322 that rotates in the opposite direction on the other side. At this time, the first screw 21 rotates in the opposite direction, thereby causing the moving part 221 to move in the opposite direction, and vice versa.

[0030] The buffer assembly 33 includes a tube 331, which is symmetrically arranged about the moving part 221. The tube 331 is fixedly connected to the moving part 221, and both sides of the tube 331 are open ends. An abutment rod 332 is slidably connected inside the tube 331. Rubber sleeves 333 are fixedly connected to both ends of the abutment rod 332. The rubber sleeves 333 can reduce wear on the surface of the placement tray 12. A spring block 334 is fixedly connected to the middle of the abutment rod 332. Springs 335 are provided at both ends of the spring block 334, and one end of the spring 335 is fixedly connected to the spring block 334. The other end of the second spring 335 is fixedly connected to the tube body 331. When the first lead screw 21 drives the moving part 221 to move along the direction of the lead screw 21, the abutting rod 332 on the moving part 221 abuts against the placement tray 12. At this time, the second spring 335 is compressed. At this time, the second spring 335 gives the moving part 221 a reverse force to drive the first lead screw 21 to move in the opposite direction. At this time, the limiting component 31 and the switching component 32 cooperate with the first lead screw 21 to rotate in the opposite direction and limit the lateral movement range of the first lead screw 21, so that the moving part 221 moves back and forth on the first lead screw 21, thereby making the cable orderly wound on the winding drum 10.

[0031] The drive assembly 25 includes a motor base 251, which is fixedly connected to the base 11. A motor 252 is housed inside the motor base 251. The outer casing of the motor 252 is fixedly connected to the motor base 251. A first idler roller 253 is fixedly connected to the end of the internal shaft of the motor 252. A second idler roller 254 is fixedly connected to one end of the winding drum 10. A connecting belt 255 connects the first idler roller 253 and the second idler roller 254. The internal shaft of the motor 252 drives the first idler roller 253 to rotate, which in turn drives the connecting belt 255 to rotate. The connecting belt 255 drives the second idler roller 254 to rotate, which in turn drives the winding drum 10 to rotate. A third bevel gear 256 is fixedly connected to the other end of the winding drum 10. A fourth bevel gear 257 meshes with one side of the third bevel gear 256. The outer side of the fourth bevel gear 257 is provided with… A gear frame 258 is fixedly connected to a placement tray 12. A bevel gear four 257 is rotatably connected to the gear frame 258. An extension rod one 259 is fixedly connected to the top of the bevel gear four 257. A non-circular groove 2591 is opened in the extension rod one 259. An extension rod two 2592 overlapping with the non-circular groove 2591 is fixedly connected to the bottom of the bevel gear two 325. The winding drum 10 drives the bevel gear three 256 to rotate, the bevel gear three 256 drives the bevel gear four 257 to rotate, the bevel gear four 257 drives the extension rod one 259 to rotate, the extension rod one 259 drives the extension rod two 2592 to rotate, and the extension rod two 2592 drives the bevel gear two 325 to rotate. Since the extension rod two 2592 is slidably connected to the extension rod one 259, the bevel gear two 325 continues to rotate when the extension rod two 2592 moves upward.

[0032] The winding drum 10 includes a winding drum seat 101, of which there are two sets. A wire-holding plate 102 is arranged in a circumferential array on one side of the winding drum seat 101. The wire-holding plate 102 is fixedly connected to the winding drum seat 101. The lead screw 21 includes a lead screw seat 103. A semi-circular plate 104 is arranged in a circumferential array on the lead screw seat 103. The semi-circular plate 104 is fixedly connected to the lead screw seat 103. A threaded strip is fixedly connected to the semi-circular plate 104. There are two sets of lead screw seats 103. The lead screw seats 103 are rotatably connected... A lead screw 105 is connected to the base 11. A hexagonal groove 106 is formed at the end of the lead screw 105. A threaded plate 107 is fixedly connected inside the semi-circular plate 104, and the threaded plate 107 is threadedly connected to the lead screw 105. A sleeve 108 is fixedly connected to one side of the base 11. A rectangular tube 109 is slidably connected inside the sleeve 108 and fixedly connected to the other side of the base 11. A threaded hole is formed at the end of the sleeve 108, and a knob 1091 is threadedly connected inside the threaded hole. Positioning rod 223 includes a limiting sleeve 2231, which is fixedly connected to sliding member 24. A positioning rod 2232 is slidably connected inside the limiting sleeve 2231. First, remove lead screw 21 from the placement plate 12. Then, insert a hexagonal wrench into the hexagonal groove 106 on lead screw 2 105 and rotate the hexagonal wrench. The hand makes the lead screw 105 rotate, and at the same time fixes the lead screw seat 103 that is threadedly connected to the lead screw 105. This causes the lead screw 105 to work with the threaded plate 107 to push the semi-circular plate 104 on the other side, adjust it to a suitable length and make the threaded strips on the semi-circular plate 104 overlap. Then loosen the knob 1091 to stretch the placement plate 12 to a suitable length on both sides. Then tighten the knob 1091 again. Finally, put the adjusted lead screw back into the placement plate 12 to achieve the purpose of extending the length of the winding drum 10.
