Description

Technical Field

[0001] This invention relates to the field of cable winding technology, and in particular to a cable winding device after production. Background Technology

[0002] A cable winding device is a specialized piece of equipment used to neatly and orderly wind up cables after they have been manufactured, so that they can be stored, transported and used. It typically consists of a winding shaft, a drive system, a tension control mechanism and other auxiliary components, designed to ensure that the cable maintains appropriate tension and neatness during the winding process.

[0003] After being produced by a multi-strand rope-making machine, the cable is conveyed out at a uniform speed to await winding. Winding is achieved by rotating a winding reel. As the winding thickness increases, the linear winding speed also increases, eventually leading to an unstable winding speed. For example, patent CN115043270B discloses a cable winding and unwinding device and its usage method with an anti-winding entanglement structure to solve this problem. By reducing the pressure received by the first pressure sensor, the retraction of the second hydraulic actuator causes the first conical disc, the first connecting rod, and the second connecting rod to move to the right until the first pressure sensor is in contact with the outer layer of the cable. Under the action of the return spring, the second conical disc contacts the outer wall of the first conical disc. The radial distance between the meshing blocks is approximately the distance from the outer layer of the cable on the cable reel to the center of the cable reel. When the motor rotation speed remains constant, the distance of one revolution between the meshing blocks, adjusted by the second hydraulic actuator, is equal to the circumference of the outermost layer of the cable reel, thus achieving uniform unwinding.

[0004] The aforementioned patent incorporates three structures—monitoring, adjustment, and driving—to achieve uniform winding and unwinding, resulting in a relatively complex structure. Summary of the Invention

[0005] The purpose of this invention is to provide a cable winding device after production, which solves the problem that existing winding equipment in the background art, in order to achieve uniform winding speed, requires complex algorithms to control the motor speed or to set up more complex structures, resulting in increased costs and inconvenient control.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable winding device after production, comprising a housing and a drive shaft rotatably disposed within the housing, with one end of the drive shaft extending to the outside of the housing. A winding roller is installed at the end of the drive shaft located outside the housing. A layer-changing mechanism and an adjustment mechanism are disposed inside the housing. The housing also contains a movable block, a first drive disc, a second drive disc, and a drive mechanism. The movable block is slidably connected inside the housing and rotatably connected to the first drive disc via a bearing. The first drive disc is slidably connected to the drive shaft. The second drive disc is fixedly connected to the end of the drive shaft located inside the housing. The drive mechanism is used to drive the drive shaft to rotate via the first and second drive discs. The layer-changing mechanism is used to drive the cable to move laterally back and forth. The adjustment mechanism is used to drive the movable block and the first drive disc to move closer to one side of the second drive disc.

[0007] The layer-changing mechanism includes a first motor fixedly connected to the top of the housing, the output end of the first motor extending into the housing and fixedly connected to a drive disk, a driven disk rotatably connected inside the housing, a synchronous belt installed between the drive disk and the driven disk, a guide rod fixedly connected below the synchronous belt, and a sliding plate slidably connected inside the housing. The sliding plate is provided with a movable groove corresponding to the guide rod, the guide rod is used to drive the sliding plate to slide laterally back and forth inside the housing, a lead wire ring is provided on the side of the movable groove, the cable passes through the lead wire ring and is wound up by the take-up roller;

[0008] The adjustment mechanism includes a T-shaped plate that is slidably connected to the inside of the housing. The T-shaped plate is located below the driven plate and corresponds to the guide rod. The guide rod is also used to push the T-shaped plate to move. The adjustment mechanism also includes a movable plate that is slidably connected to the inside of the housing. A ratchet gear set is provided inside the housing at the intersection of the T-shaped plate and the movable plate. A telescopic cylinder and a limiting tooth block are provided inside the housing for unidirectional limiting of the movable plate.

[0009] The movable plate is fixedly connected to the movable block. The driving mechanism includes a transmission wheel rotatably disposed inside the housing and a tensioning wheel movably disposed inside the housing. A transmission steel belt is installed between the tensioning wheel, the transmission wheel, and the first and second transmission discs. The cross-section of the transmission steel belt is an inverted trapezoid. The inner sides of the first and second transmission discs are in contact with the two sides of the transmission steel belt.

[0010] Furthermore, a first spring is provided inside the outer casing, with one end of the first spring fixedly connected to the interior of the outer casing and the other end of the first spring fixedly connected to the T-shaped plate.

[0011] Furthermore, the ratchet gear set includes a first gear rotatably disposed inside the housing and a second gear rotatably connected above the first gear. The lower part of the second gear is rotatably connected to the first gear. The inner side of the first gear has a preset groove evenly distributed. The inside of the preset groove is connected to a ratchet block by a second spring. The lower outer wall of the second gear has a slot corresponding to the ratchet block evenly distributed.

[0012] Furthermore, the T-shaped plate is provided with a first tooth groove that meshes with the first gear, and the movable plate is provided with a second tooth groove that corresponds to the second gear.

[0013] Furthermore, a third spring is provided between the output end of the telescopic cylinder and the limiting tooth block. The limiting tooth block is slidably connected to the inside of the outer shell. The movable plate is provided with a third tooth groove corresponding to the limiting tooth block. The cross-section of the third tooth groove and the tooth on the limiting tooth block is a right triangle. When the first motor drives the synchronous belt drive, the guide rod drives the sliding plate to slide laterally back and forth inside the outer shell. When the guide rod moves close to the driven plate, it moves the T-shaped plate. The T-shaped plate drives the movable plate to move through the ratchet gear set. When the movable plate moves to the right, it passes through the movable block. The first transmission disc is moved to one side of the second transmission disc, so that the diameter of the transmission steel belt between the first and second transmission discs is adapted to the diameter of the cable on the take-up roller. Then, the T-shaped plate is reset. Under the action of the telescopic cylinder, the limit tooth block, and the ratchet gear set, the movable plate is restricted to reset. Then, when the guide rod moves to the driven disc again, the first transmission disc is moved to one side of the second transmission disc again through the T-shaped plate, the movable plate, and the movable block, and the diameter of the transmission steel belt is adjusted again to adapt to the diameter of the cable on the take-up roller. This achieves deceleration adjustment to ensure a constant take-up speed.

[0014] Furthermore, a return spring is also provided inside the outer shell. One end of the return spring is fixedly connected to the inside of the outer shell, and the other end of the return spring is fixedly connected to the movable block. When the winding is completed, it is retracted by the telescopic cylinder, the limit tooth block releases the restriction on the movable plate, and the movable block and the first transmission plate are reset under the action of the return spring.

[0015] Furthermore, the drive shaft has evenly distributed limit strips at one end near the inside of the housing, and the first drive disc is provided with a groove corresponding to the limit strips.

[0016] Furthermore, the drive mechanism also includes a second motor fixedly mounted outside the housing. The output end of the second motor extends into the interior of the housing and is equipped with a transmission wheel. The second motor is used to drive the transmission wheel to rotate, and the transmission wheel is slidably connected to the output end of the second motor.

[0017] Furthermore, the tensioning wheel includes a spring fixedly installed inside the housing, a movable frame slidably installed inside the housing, and a movable roller movably installed on the movable frame, with one end of the spring fixedly connected to the movable frame.

[0018] Furthermore, the cross-section of the ratchet block is a right trapezoid, and the cross-section of the slot is a right triangle. When the T-shaped plate slides backward, it drives the first gear to rotate clockwise. Under the action of the ratchet block and the slot, it drives the second gear to rotate clockwise. The second gear meshes with the second tooth groove, causing the movable plate to move to the right.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention provides a cable winding device after production. A first motor drives a synchronous belt and a guide rod, which in turn drives a sliding plate to move laterally and reciprocally, causing the cable to be evenly wound onto the winding roller. When the guide rod moves to the driven disc, it presses against a T-shaped plate. Under the action of the T-shaped plate, ratchet gear set, movable plate, and movable block, the first transmission disc moves closer to the second transmission disc. After the first transmission disc moves towards the second transmission disc, it presses against the transmission steel belt, causing the transmission steel belt to move outward between the first and second transmission discs. This ensures that the size of the transmission steel belt between the first and second transmission discs matches the diameter of the cable outside the winding roller, ultimately maintaining uniform winding speed. The structure is simple and reliable. Attached Figure Description

The first transmission disc 6 is slidably connected to the drive shaft 71. The second transmission disc 7 is fixedly connected to the end of the drive shaft 71 located inside the housing 1. The drive mechanism 8 is used to drive the drive shaft 71 to rotate via the first transmission disc 6 and the second transmission disc 7. The layer-changing mechanism 2 is used to drive the cable to move laterally back and forth. The adjustment mechanism 3 is used to drive the movable block 5 and the first transmission disc 6 to move closer to one side of the second transmission disc 7.

[0033] like Figure 3As shown, the layer-changing mechanism 2 includes a first motor 21 fixedly connected to the top of the outer shell 1. The output end of the first motor 21 extends into the interior of the outer shell 1 and is fixedly connected to a drive disk 211. A driven disk 212 is rotatably connected inside the outer shell 1. The layer-changing mechanism 2 also includes a synchronous belt 22 installed between the drive disk 211 and the driven disk 212. A guide rod 24 is fixedly connected below the synchronous belt 22. The layer-changing mechanism 2 also includes a sliding plate 23 slidably connected inside the outer shell 1. The sliding plate 23 is provided with a movable groove 231 corresponding to the guide rod 24. The guide rod 24 is used to drive the sliding plate 23 to slide laterally back and forth inside the outer shell 1. A lead wire ring 232 is provided on the side of the movable groove 231. The cable passes through the lead wire ring 232 and is wound up by the winding roller 4.

[0034] The adjustment mechanism 3 includes a T-shaped plate 31 that is slidably connected to the inside of the housing 1. The T-shaped plate 31 is located below the driven plate 212 and corresponds to the guide rod 24. The guide rod 24 is also used to push the T-shaped plate 31 to move. When the guide rod 24 moves close to the driven plate 212, it moves the T-shaped plate 31. The adjustment mechanism 3 also includes a movable plate 33 that is slidably connected to the inside of the housing 1. A ratchet gear set 32 ​​is provided inside the housing 1 at the intersection of the T-shaped plate 31 and the movable plate 33. A telescopic cylinder 34 and a limiting tooth block 35 are provided inside the housing 1 for unidirectional limiting of the movable plate 33.

[0035] The movable plate 33 is fixedly connected to the movable block 5. The drive mechanism 8 includes a transmission wheel 82 rotatably disposed inside the housing 1, and a tension wheel 84 movably disposed inside the housing 1. A transmission steel belt 83 is installed between the tension wheel 84, the transmission wheel 82, the first transmission disc 6, and the second transmission disc 7. The cross-section of the transmission steel belt 83 is an inverted trapezoid. The inner sides of the first transmission disc 6 and the second transmission disc 7 are in contact with the two sides of the transmission steel belt 83.

[0036] like Figure 5 As shown, a first spring 312 is provided inside the outer casing 1. One end of the first spring 312 is fixedly connected to the inside of the outer casing 1, and the other end of the first spring 312 is fixedly connected to the T-shaped plate 31. The first spring 312 is used for the reset of the T-shaped plate 31.

[0037] like Figures 5-6As shown, the ratchet gear set 32 ​​includes a first gear 321 rotatably disposed inside the housing 1 and a second gear 323 rotatably connected above the first gear 321. The lower part of the second gear 323 is rotatably connected to the first gear 321. The inner side of the first gear 321 has a preset groove 322 evenly distributed. The interior of the preset groove 322 is connected to a ratchet block 326 by a second spring 325. The lower outer wall of the second gear 323 has a slot 324 evenly distributed corresponding to the ratchet block 326. When the first gear 321 rotates clockwise, it will drive the second gear 323 to rotate clockwise as well. However, when the first gear 321 rotates counterclockwise, it will not drive the second gear 323 to rotate counterclockwise.

[0038] The T-shaped plate 31 is provided with a first tooth groove 311 that meshes with the first gear 321, and the movable plate 33 is provided with a second tooth groove 331 that corresponds to the second gear 323.

[0039] A third spring 341 is provided between the output end of the telescopic cylinder 34 and the limiting tooth block 35. The limiting tooth block 35 is slidably connected to the inside of the outer shell 1. The movable plate 33 is provided with a third tooth groove 332 corresponding to the limiting tooth block 35. The cross-section of the third tooth groove 332 and the tooth on the limiting tooth block 35 is a right-angled triangle. When the first motor 21 drives the synchronous belt 22, the guide rod 24 drives the sliding plate 23 to slide laterally back and forth inside the outer shell 1. When the guide rod 24 moves close to the driven plate 212, it moves the T-shaped plate 31. The T-shaped plate 31 drives the movable plate 33 to move through the ratchet gear set 32. When the movable plate 33 moves to the right, it drives the T-shaped plate 31 to move. The moving block 5 drives the first transmission disc 6 to move to one side of the second transmission disc 7, so that the diameter of the transmission steel belt 83 between the first transmission disc 6 and the second transmission disc 7 is adapted to the diameter of the cable on the take-up roller 4. Then the T-shaped plate 31 is reset. Under the action of the telescopic cylinder 34, the limiting tooth block 35 and the ratchet gear set 32, the movable plate 33 is restricted to reset. Then, when the guide rod 24 moves to the driven disc 212 again, the first transmission disc 6 is moved to one side of the second transmission disc 7 again through the T-shaped plate 31, the movable plate 33 and the moving block 5, and the diameter of the transmission steel belt 83 is adjusted again to adapt to the diameter of the cable on the take-up roller 4, so as to achieve deceleration adjustment to meet the constant winding speed.

[0040] like Figure 8 As shown, a reset spring 52 is also provided inside the outer casing 1. One end of the reset spring 52 is fixedly connected to the inside of the outer casing 1, and the other end of the reset spring 52 is fixedly connected to the movable block 5. When the winding is completed, it is retracted by the telescopic cylinder 34, and the limiting tooth block 35 releases the restriction on the movable plate 33. Under the action of the reset spring 52, the movable block 5 and the first transmission disc 6 are reset.

[0041] Limiting strips 711 are evenly distributed at one end of the drive shaft 71 near the inside of the outer casing 1, and the first drive disc 6 is provided with a sliding groove corresponding to the limiting strips 711.

[0042] like Figure 8 As shown, the drive mechanism 8 also includes a second motor 81 fixedly disposed outside the housing 1. The output end of the second motor 81 extends into the interior of the housing 1 and is equipped with a transmission wheel 82. The second motor 81 is used to drive the transmission wheel 82 to rotate, and the transmission wheel 82 is slidably connected to the output end of the second motor 81.

[0043] The tensioning wheel 84 includes a spring fixedly installed inside the housing 1, a movable frame slidably installed inside the housing 1, and a movable roller movably installed on the movable frame, with one end of the spring fixedly connected to the movable frame.

[0044] like Figures 5-6 As shown, the cross-section of the ratchet block 326 is a right trapezoid, and the cross-section of the slot 324 is a right triangle. When the T-shaped plate 31 slides backward, it drives the first gear 321 to rotate clockwise. Under the action of the ratchet block 326 and the slot 324, it drives the second gear 323 to rotate clockwise. The second gear 323 meshes with the second tooth groove 331, causing the movable plate 33 to move to the right.

[0045] Specifically, the take-up roller 4 is mounted on the drive shaft 71. The cable, produced by the multi-strand rope making machine, passes through the lead ring 232 and is fixed to the take-up roller 4. Then, the second motor 81 and the first motor 21 are started. The transmission steel belt 83 drives the drive shaft 71 via the first transmission disc 6 and the second transmission disc 7 to perform winding. Simultaneously, the first motor 21 drives the synchronous belt 22 and the guide rod 24, which in turn drives the sliding plate 23 to move laterally back and forth, ensuring the cable is evenly wound around the take-up roller 4. When the guide rod 24 moves to the driven disc 212... The guide rod 24 presses against the T-shaped plate 31, and under the action of the T-shaped plate 31, ratchet gear set 32, movable plate 33 and movable block 5, the first transmission disc 6 moves closer to the second transmission disc 7. After the first transmission disc 6 moves to the second transmission disc 7, it presses against the transmission steel belt 83, causing the transmission steel belt 83 to move outward between the first transmission disc 6 and the second transmission disc 7. This principle is similar to a CVT gearbox, so that the size of the transmission steel belt 83 between the first transmission disc 6 and the second transmission disc 7 matches the diameter of the outer cable of the take-up roller 4, and finally maintains uniform speed winding.
