Description

Technical Field

[0001] This invention relates to the field of cable manufacturing equipment, and more particularly to a continuously variable diameter and width cable coiling device. Background Technology

[0002] Cables are crucial relay media for power transmission and are indispensable core components for the development of my country's communications and power industries. With the rapid development of the cable industry, the cable market is becoming increasingly diversified and segmented, and customers' demand for small-batch customized products is gradually rising. At this stage, some short-length cables of small to medium specifications must be coiled and packaged according to customer requirements, which places demands on cable coiling technology.

[0003] Relying solely on traditional manual methods for winding cables into coils is inefficient and labor-intensive, clearly insufficient to meet the demands of the massive cable market. Consequently, mechanical devices specifically designed for coiling and packaging cables have been introduced, enabling the coiling technology to evolve from purely manual operation to semi-automation or even full automation.

[0004] The currently developed coiling equipment cannot adjust the parameters of the coiling reel without limitation according to the inner diameter and width of the cable coil. The coil size is limited, and the produced cable coils cannot well meet the more detailed actual needs of customers.

[0005] Therefore, there is an urgent need to develop a cable coiling device with stepless diameter and width adjustment functions that is more convenient to operate and has superior performance. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a continuously variable diameter and width cable coiling device.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A continuously variable diameter and width cable coiling device includes a bracket, a coiling module, a diameter-changing module, and a width-changing module. The loop-forming module includes a support component, a loop-forming component rotatably mounted on the support component, and a first driving component for driving the loop-forming component to rotate. The coiling assembly includes a first rotating wheel rotatably connected to the support assembly and a plurality of cable winding rods arranged circumferentially along the first rotating wheel. The plurality of cable winding rods enclose each other to form a circumferential coiling frame for coiling cables. The variable diameter module includes a first connecting shaft coaxially arranged with the first rotating wheel, a movable component screw-driven to the first connecting shaft, and a transmission component connected to the movable component. The first connecting shaft and the first rotating wheel can rotate synchronously or relative to each other. The transmission component is connected to the cable winding rod. When the first connecting shaft and the first rotating wheel rotate relative to each other, the first rotating wheel drives the moving part to move axially along the first connecting shaft, and the transmission part synchronously drives the winding rod to move radially along the first rotating wheel, so as to realize stepless adjustment of the inner diameter of the coil. The widening module includes a moving component, a widening blocking member disposed on the moving component, and a second driving member for driving the moving component to move. The widening blocking member can move along the axial direction of the winding rod and, together with the first rotating wheel, defines the loop width. The second driving member drives the moving component to move along the axial direction of the cable rod, and simultaneously drives the widening blocking member to move closer to or further away from the first rotating wheel, so as to achieve stepless adjustment of the loop width.

[0009] More specifically, a first braking assembly is provided on the first connecting shaft, the first braking assembly including a first brake disc and a first braking element for controlling the start and stop of the first brake disc; During the diameter change operation, the first braking component controls the first brake disc to stop rotating, the first connecting shaft stops rotating synchronously, and the first driving component drives the first rotating wheel to rotate, so that the first connecting shaft and the first rotating wheel rotate relative to each other.

[0010] More specifically, a tension adjustment structure is provided on the first connecting shaft, and a tension wheel is provided on the first rotating wheel. The tension adjustment structure elastically abuts against the outer circumferential surface of the tension wheel. The tension adjustment structure applies a circumferential elastic damping force to the tension wheel to suppress the unexpected rotation of the first connecting shaft relative to the first rotating wheel when the coiling module coils the cable, thereby maintaining the synchronization of the two.

[0011] More specifically, the tension adjustment structure includes a tension adjustment cylinder, a telescopic spring, an adjustment bolt, a tension conveying rod, a tension fixing frame, a roller shaft, and a roller; The tension adjusting cylinder is connected to the first connecting shaft. The telescopic spring is disposed in the tension adjusting cylinder. The adjusting bolt passes through one end of the tension adjusting cylinder and contacts the telescopic spring. The tension conveying rod passes through the other end of the tension adjusting cylinder and contacts the telescopic spring. The tension conveying rod is connected to the tension fixing frame. The roller is disposed on the roller shaft, which is connected to the tension fixing frame. The tension wheel is configured as a cam with a wavy outer circumference. The roller abuts against the wavy outer circumference of the tension wheel under the elastic force of the telescopic spring.

[0012] More specifically, a variable diameter thread is provided on the first connecting shaft, and the moving part is connected to the variable diameter thread; The transmission component includes a plurality of fixed lugs disposed on the moving component, a plurality of first hinges disposed on the fixed lugs, a plurality of connecting rods connected to the first hinges, a plurality of second hinges connected to the connecting rods, and a plurality of external fixed lugs connected to the cable winding rod. When the moving part rotates along the variable diameter thread, it will generate axial movement along the first connecting shaft. The connecting rod rotates around the first hinge and / or the second hinge, pulling the cable rod to move radially along the first wheel.

[0013] More specifically, a plurality of first variable diameter holes are provided on the first rotating wheel. The first variable diameter holes are arranged radially outward from the first rotating wheel. The cable winding rod is arranged in the first variable diameter holes and can move along the first variable diameter holes.

[0014] More specifically, a second motor is provided on the moving component, and a second connecting shaft is provided on the widening blocking component. The second connecting shaft is connected to the second motor, and the second motor drives the second connecting shaft to rotate, which in turn drives the widening blocking component to rotate.

[0015] More specifically, the widening blocking component is configured as a widening rotating wheel, and a clearance opening is provided on the widening rotating wheel. A plurality of clearance openings are provided, and the plurality of clearance openings are arranged radially along the widening rotating wheel. The cable winding rod is inserted into the clearance opening, and the cable winding rod is arranged in a one-to-one correspondence with the clearance opening.

[0016] More specifically, the moving component includes a slide rail mounted on the bracket, a slider mounted on the slide rail, and a fixed seat mounted on the slider. The slide rail extends axially along the winding rod, the fixed seat is mounted on the slider, and the second motor is mounted on the fixed seat.

[0017] More specifically, a widening braking assembly is provided on the second connecting shaft, the widening braking assembly including a widening brake disc and a widening braking element for controlling the widening brake disc to stop rotating; During the widening adjustment or cable unwinding, the widening brake component controls the widening brake disc to stop rotating, simultaneously stopping the widening wheel from rotating.

[0018] This invention addresses the shortcomings of the prior art and has the following beneficial effects: By setting a variable diameter structure, the circumference formed by the cable rod can be set to any diameter. By using a widening module, the distance between the adjustment component and the first rotating wheel can be adjusted arbitrarily to obtain any width. Attached Figure Description

Therefore, they should not be construed as limiting the scope of protection of this invention. The embodiments of this invention will now be described in detail with reference to the accompanying drawings.

[0022] It should be understood that the accompanying drawings are for illustrative purposes only.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0024] A continuously variable diameter and width cable coiling device, such as Figures 1-11 As shown, it includes a bracket 1, a coiling module 2, a diameter-changing module 3, and a width-changing module 4. The coiling module 2, the diameter-changing module 3, and the width-changing module 4 are all mounted on the bracket 1. The cable is wound around the coiling module 2. The diameter-changing module 3 adjusts the diameter, and the width-changing module 4 adjusts the width.

[0025] The coiling module 2 includes a support component, a coiling component disposed on the support component, and a first driving member for driving the coiling component to rotate. The support component enables the coiling component to rotate, and the first driving member drives the coiling component to rotate on the support component. The cable is wound into a coil on the coiling component.

[0026] The support assembly includes a support frame 21, which is mounted on the bracket 1. The ring-forming assembly is mounted on the support frame 21 and can rotate on the support frame 21.

[0027] The coiling assembly includes a first rotating wheel 22 disposed on the support assembly and a cable winding rod 23 disposed circumferentially along the first rotating wheel 22. The first rotating wheel 22 is rotatably disposed on the support assembly. Furthermore, the first rotating wheel 22 is disposed on a support frame 21. A receiving opening is provided in the middle of the support frame 21, and the first rotating wheel 22 is disposed in the receiving opening. A connecting structure is provided on the support frame 21 so that the first rotating wheel 22 is rotatably disposed in the receiving opening within the support frame 21.

[0028] The cable winding rod 23 is mounted on the first rotating wheel 22 and rotates synchronously with the first rotating wheel 22. When the first driving member drives the first rotating wheel 22 to rotate, the cable winding rod 23 rotates accordingly, so that the cable is wound around the cable winding rod 23 to form a loop.

[0029] A plurality of cable winding rods 23 are provided, and the plurality of cable winding rods 23 are arranged to form a circumferential winding frame for coiling the cable, so that the cable can be coiled and wound around the cable winding rods 23. The axial direction of the plurality of cable winding rods 23 is parallel to the axial direction of the first rotating wheel 22, and the distance from the axis of the plurality of cable winding rods 23 to the axis of the first rotating wheel 22 is the same, ensuring the diameter of the cable after coiling.

[0030] A U-shaped groove 231 is provided at the end of the cable winding rod 23 to facilitate placing one end of the cable in the U-shaped groove 231 before cabling, thus preventing the cable from falling off during cabling. The U-shaped groove 231 can be provided on only one cable winding rod 23, or on each of the cable winding rods 23, or every other one.

[0031] The first driving component is mounted on the support frame 21 and includes a first motor 24, a pulley 25, a drive wheel 26, and a belt 27.

[0032] The first motor 24 is mounted on the support frame 21. Specifically, when the outer periphery of the support frame 21 is circular, a motor mounting base 413 is mounted on the support frame 21, and the first motor 24 is fixed on the motor mounting base 413 to avoid unreliable connection between the first motor 24 and the support frame 21. When the outer periphery of the support frame 21 is square or rectangular or other planar shapes, there is no need to mount the motor mounting base 413.

[0033] A plurality of pulleys 25 are arranged evenly along the first rotating wheel 22. Each pulley 25 is connected to a drive wheel 26, which contacts the outer periphery of the first rotating wheel 22. The pulleys 25 are connected in pairs along belts 27. The first pulley 25 is connected to the first motor 24 via belts 27, and the last pulley 25 is not connected to the first pulley 25. This ensures that the first motor 24 drives the first pulley 25 via belts 27, synchronously driving all the pulleys 25. Since each pulley 25 is connected to a drive wheel 26, the drive wheel 26 rotates when the corresponding pulley 25 rotates. Because the drive wheel 26 contacts the outer periphery of the first rotating wheel 22, the first rotating wheel 22 rotates in the opposite direction to the drive wheel 26. The start, stop, and rotation of the first rotating wheel 22 are controlled by controlling the start, stop, and rotation of the first motor 24.

[0034] To ensure the rotation of the pulley 25 and the drive wheel 26, and the connection between the first wheel 22 and the support frame 21, the connection structure includes a pulley connecting plate 251 and a drive wheel connecting plate 261 mounted on the support frame 21. A drive connecting shaft 262 passes through the pulley connecting plate 251 and the drive wheel connecting plate 261. The pulley 25 and the drive wheel 26 are both mounted on the drive connecting shaft 262. The drive wheel 26 is positioned between the pulley connecting plate 251 and the drive wheel connecting plate 261. The pulley 25 is positioned on the pulley connecting plate 251. On the side of plate 251 away from drive wheel connecting plate 261, bearings are provided on both the pulley connecting plate 251 and drive wheel connecting plate 261, allowing the drive connecting shaft 262 to rotate on both plates. When the first motor 24 drives the pulley 25 to rotate, the pulley 25 drives the drive connecting shaft 262 to rotate synchronously, which in turn drives the drive wheel 26 to rotate synchronously. The drive wheel 26 then drives the first rotating wheel 22 to rotate in the opposite direction. The pulley connecting plate 251, drive wheel connecting plate 261, and drive wheel 26 work together to rotatably connect the first rotating wheel 22 to the support frame 21.

[0035] To further ensure the driving effect of the drive wheel 26 on the first rotating wheel 22, a placement groove 221 is provided on the first rotating wheel 22. The width of the placement groove 221 matches that of the drive wheel 26, so that the drive wheel 26 is accommodated in the placement groove 221. Furthermore, the placement groove 221 is located on the outer periphery of the first rotating wheel 22. When the drive wheel 26 drives the first rotating wheel 22 to rotate, it prevents the drive wheel 26 from moving axially along the drive connecting shaft 262, thus ensuring reliable driving of the first rotating wheel 22.

[0036] When it is necessary to stop the rotation of the first rotating wheel 22, the first motor 24 can be turned off. However, in order to make the first rotating wheel 22 stop rotating immediately when it is necessary to stop rotating, a first electromagnetic brake is provided on the first motor 24. By controlling the first electromagnetic brake, the starting and immediate stopping of the first motor 24 can be controlled.

[0037] To prevent the cable from rubbing against the support frame 21 when the cable is being wound up, a clearance opening 451 is provided on the side of the support frame 21 near the cable winding rod 23.

[0038] A diameter-changing module 3 is provided to allow free adjustment of the diameter of the cable after coiling. The diameter-changing module 3 adjusts the diameter by changing the distance between the axis of several cable-winding rods 23 and the axis of the first rotating wheel 22. The diameter-changing module 3 includes a first connecting shaft 31, a diameter-changing thread 311, a moving part disposed on the diameter-changing thread 311, a transmission part disposed on the moving part, a tension adjustment structure 33, and a tension wheel 30.

[0039] The first connecting shaft 31 is coaxially arranged with the first rotating wheel 22. The first connecting shaft 31 can rotate synchronously with the first rotating wheel 22 or rotate relative to the first rotating wheel 22. When the first connecting shaft 31 and the first rotating wheel 22 rotate relative to each other, the first rotating wheel 22 rotates around the first connecting shaft 31.

[0040] To ensure diameter accuracy, the first connecting shaft 31 must stop immediately when necessary. Therefore, a first braking assembly is provided on the first connecting shaft 31. The first connecting shaft 31 is set to a normally open state, meaning that when the first connecting shaft 31 is normally rotating, applying braking force to the first connecting shaft 31 will immediately stop its rotation. Furthermore, the first braking assembly includes a first brake disc 37 and a first braking element 36 for controlling the start and stop of the first brake disc 37. To drive the first braking element 36 to move, a first drive cylinder 35 is provided on the bracket 1. The first braking element 36 is mounted on the first drive cylinder 35. Through the extension and retraction of the first drive cylinder 35, the first braking element 36 is driven to contact or separate from the first brake disc 37 on the first connecting shaft 31, so that the first connecting shaft 31 immediately stops rotating or maintains rotation. Specifically, the first brake disc 37 is disposed at the end of the first connecting shaft 31, and the first drive cylinder 35 includes a fixed part and a telescopic part. The fixed part is fixed on the bracket 1, and the telescopic part is disposed on the fixed part and can extend or retract from the fixed part. The first brake member 36 is disposed at the end of the telescopic part away from the fixed part. The shape of the first brake member 36 is adapted to the first brake disc 37, so that when the first brake member 36 controls the first brake disc 37 to stop rotating, the first connecting shaft 31 will immediately stop rotating.

[0041] Furthermore, to ensure reliable rotation of the first rotating wheel 22 around the first connecting shaft 31, a bearing sleeve is fitted onto the first connecting shaft 31, and an intermediate bearing 38 is provided on the bearing sleeve. The outer side of the intermediate bearing 38 is connected to the first rotating wheel 22. Specifically, the intermediate bearing 38 and the first rotating wheel 22 are interference-fitted. The bearing sleeve ensures that the intermediate bearing 38 can be stably connected to the first connecting shaft 31, and that it will not be displaced along the first connecting shaft 31 when it rotates. It also prevents wear on the first connecting shaft 31 when the intermediate bearing 38 rotates.

[0042] Because the contact surface between the first rotating wheel 22 and the first connecting shaft 31 is large, multiple intermediate bearings 38 can be provided. In this solution, two intermediate bearings 38 are provided.

[0043] To further prevent the first rotating wheel 22 and / or the intermediate bearing 38 from axially displacing along the first connecting shaft 31, a blocking member 39 is provided on the first connecting shaft 31. A connecting through hole is provided in the middle of the first rotating wheel 22, which is used to connect with the first connecting shaft 31. The outer circumference of the blocking member 39 on the side closer to the first rotating wheel 22 is larger than the connecting through hole, ensuring that the blocking member 39 axially blocks the first rotating wheel 22. A through hole is provided in the middle of the blocking member 39, which is clearance-fitted with the first connecting shaft 31. A connecting hole 391 is provided on the blocking member 39, which is evenly distributed along the circumference of the blocking member 39. A pin is inserted into the connecting hole 391 to connect the blocking member 39 to the first connecting shaft 31, preventing the blocking member 39 from displacing and further preventing the first rotating wheel 22 and / or the intermediate bearing 38 from displacing. Because the blocking member 39 needs to block the movement of the first rotating wheel 22, its outer perimeter is relatively large. However, if a pin is to be inserted, a large outer perimeter would be inconvenient. Therefore, the outer perimeter of the part of the blocking member 39 furthest from the first rotating wheel 22 is made smaller, and the pin is placed at the smaller outer perimeter position for easy insertion. In this design, the blocking member 39 is cylindrical, with the diameter of the end furthest from the first rotating wheel 22 being smaller than the diameter of the end closest to the first rotating wheel 22.

[0044] A retaining ring for a hole is provided on the first connecting shaft 31. The retaining ring for a hole is located between the intermediate bearing 38 and the blocking member 39. The retaining ring for a hole is in close contact with the inner ring of the intermediate bearing 38, further blocking the axial movement of the intermediate bearing 38.

[0045] A placement groove is provided at the end of the blocking member 39 near the first rotating wheel 22. The tension adjusting structure 33 is disposed within the placement groove. The tension wheel 30 is disposed between the blocking member 39 and the first rotating wheel 22. The tension adjusting structure 33 elastically abuts against the outer peripheral surface of the tension wheel 30. The tension wheel 30 is connected to the first rotating wheel 22. Further, the tension wheel 30 can be configured as a cam. In this embodiment, the tension wheel 30 is configured as a cam with a wavy outer peripheral surface.

[0046] The tension adjustment structure 33 includes a tension adjustment cylinder 331, a telescopic spring, an adjustment bolt 332, a tension conveying rod 333, a tension fixing frame 334, a roller 335, a rotating shaft, and a roller 335.

[0047] The tension adjusting cylinder 331 is connected to the limiting member. The tension adjusting cylinder 331 is hollow inside. The telescopic spring is disposed inside the tension adjusting cylinder 331. A threaded hole is provided at the top of the tension adjusting cylinder 331. The adjusting bolt 332 is connected to the threaded hole. The adjusting bolt 332 passes through the top of the tension adjusting cylinder 331 and contacts the telescopic spring. By rotating the adjusting bolt 332, the length of the adjusting bolt 332 extending into the tension adjusting cylinder 331 is adjusted. An adjustment hole is provided at the bottom of the tension adjusting cylinder 331. The tension conveying rod 333 passes through the bottom of the tension adjusting cylinder 331 and contacts the telescopic spring. One end of the tension conveying rod 333 extends into the tension adjusting cylinder 331 from the adjustment hole. The other end of the tension conveying rod 333 is connected to the tension fixing frame 334. The tension fixing frame 334 is located on the outside of the tension adjusting cylinder 331. The roller 335 is located on the roller shaft. The roller shaft is connected to the tension fixing frame 334. The roller 335 abuts against the wavy outer circumferential surface of the tension wheel 30 by the elastic force of the telescopic spring. Specifically, the tension fixing frame 334 includes a first fixing rod, a second fixing rod, and a third fixing rod. The first fixing rod is connected to the tension conveying rod 333, and a portion of the first fixing rod extends into the placement groove. The second and third fixing rods are both connected to the first fixing rod, and both the second and third fixing rods are located on the side of the first rod away from the tension conveying rod 333. The second fixing rod is located in the placement groove, and a placement space is left between the second and third fixing rods. The roller 335 is disposed in the placement space and contacts the tension wheel 30. Furthermore, the roller shaft passes through the roller 335, and both ends of the roller shaft are connected to the second and third fixing rods respectively, so that the roller 335 can rotate within the placement space.

[0048] One end of the telescopic spring is in contact with the adjusting bolt 332, and the other end is in contact with the tension conveying rod 333. By adjusting the length of the adjusting bolt 332 extending into the tension adjusting cylinder, the adjusting bolt 332 can compress or relax the compression spring.

[0049] The tension adjustment structure 33 applies a circumferential elastic damping force to the tension wheel 30 to suppress the unexpected rotation of the first connecting shaft 31 relative to the first rotating wheel 22 when the coiling module is coiling the cable, and to maintain the synchronization of the two.

[0050] When the first rotating wheel 22 rotates relative to the first connecting shaft 31, the driving force of the first rotating wheel 22 is greater than the strength of the telescopic spring, and the telescopic spring is compressed. The tension wheel 30 rotates at the same speed as the first rotating wheel 22. When the first rotating wheel 22 rotates and the first connecting shaft 31 also rotates synchronously, the roller 335 and the tension wheel 30 remain relatively stationary. Due to long-term rotation, the speed of the first rotating wheel 22 and / or the first connecting shaft 31 changes, causing their rotation to be asynchronous. At this time, the driving force of the tension wheel 30 is less than the strength of the telescopic spring, and the telescopic spring cannot be compressed. The roller 335 cannot move from the concave part to the protruding part of the wavy tension wheel 30, and the speed of the first rotating wheel 22 and / or the first connecting shaft 31 gradually synchronizes.

[0051] The variable diameter thread 311 is formed on the first connecting shaft 31. A moving part is provided on the variable diameter thread 311. The moving part is a variable diameter nut 321. The transmission part can be configured to drive the cable rod to move radially along the first rotating wheel 22 when the variable diameter nut 321 moves axially along the first connecting shaft 31. In this solution, the transmission part includes a fixed ear plate 322, a first hinge, a connecting rod 323, a second hinge 324, and an outer fixed ear plate 325.

[0052] The reducing nut 321 is disposed on the reducing thread 311, and the reducing nut 321 can rotate on the reducing thread 311, thereby moving axially along the first connecting shaft 31. Further, a fixing lug 322 is disposed on the reducing nut 321, and the fixing lug 322 is fixed to the reducing nut 321. Several fixing lugs 322 are disposed, and these lugs are evenly distributed along the circumference of the reducing nut 321. Several connecting rods 323 and first hinges are disposed, and the connecting rods 323 are connected to the fixing lugs 322 via the first hinges. Several external fixing lugs 325 and second hinges 324 are provided. Each external fixing lug 325 is connected to the cable winding rod 23. The connecting rod 323 is connected to the external fixing lugs 325 via the second hinges 324. The number of external fixing lugs 325 and the cable winding rod 23 are the same. The fixing lugs 322, first hinges, connecting rods 323, second hinges 324, external fixing lugs 325, and cable winding rod 23 are arranged in a one-to-one correspondence. The connecting rod 323 can rotate around the first hinge and / or the second hinge 324. When the variable diameter nut 321 moves along the variable diameter thread 311, the connecting rod 323 begins to rotate around the first hinge and / or the second hinge 324, thereby driving the cable winding rod 23 to move radially along the first rotating wheel 22, changing the distance between the axis of the cable winding rod 23 and the axis of the first rotating wheel 22, thus changing the diameter of the cable loop.

[0053] To facilitate the radial movement of the cable winding rod 23 along the first rotating wheel 22 to change the coil diameter of the cable, a plurality of first diameter-changing holes 222 are provided on the first rotating wheel 22. The first diameter-changing holes 222 are elongated holes, radiating radially from the first rotating wheel 22. The cable winding rod 23 is disposed within the first diameter-changing holes 222 and can move along them. The number of first diameter-changing holes 222 is equal to or greater than the number of cable winding rods 23. The first diameter-changing holes 222 are made as large as possible in the radial direction to increase the adjustable range of the coil diameter and achieve stepless diameter change.

[0054] To further ensure the connection between the first connecting shaft 31 and the first variable diameter hole 222, a limiting nut 232 is provided at the end of the cable winding rod 23 near the first rotating wheel 22. After the cable winding rod 23 passes through the first variable diameter hole 222, the limiting nut 232 connects to the cable winding rod 23 from the side of the first rotating wheel 22 away from the cable winding rod 23, allowing the cable winding rod 23 to pass through the first variable diameter hole 222 and connect to the first rotating wheel 22, and to move along the first variable diameter hole 222. A clearance plane is provided on the limiting nut 232 to prevent interference between the limiting nut 232 and the first rotating wheel 22, thus avoiding affecting the connection.

[0055] In this scheme, since the tension wheel 30 is connected to the first rotating wheel 22, when the first driving member drives the first rotating wheel 22 to rotate, the tension wheel 30 rotates accordingly. The tension adjustment structure 33 is set on the blocking member 39, and the blocking member 39 is connected to the first connecting shaft 31. When both the first connecting shaft 31 and the first rotating wheel 22 rotate, the tension adjustment structure 33 and the tension wheel 30 need to rotate synchronously. If the rotation is not synchronous, the variable diameter structure may start to rotate around the first connecting shaft 31, thereby driving the cable rod 23 to move radially along the first rotating wheel 22, changing the diameter formed between the cable rods 23. By setting the tension adjustment structure 33 and the tension wheel 30, the rotation of the first rotating wheel 22 and the first connecting shaft 31 is synchronized. Specifically, when the first connecting shaft 31 or the first rotating wheel 22 rotates faster or slower, the rotation speed of the first connecting shaft 31 or the first rotating wheel 22 is adjusted by the tension adjustment structure 33, so that the first connecting shaft 31 and the first rotating wheel 22 rotate synchronously, ensuring the accuracy of the diameter formed between several cable rods 23.

[0056] To adjust the width of the cable after it is coiled, a widening module 4 is provided. The widening module 4 includes a moving component, a widening blocking component disposed on the moving component, and a second driving component that drives the moving component to move.

[0057] The moving component includes a slide rail 411, a slider 412 mounted on the slide rail 411, and a fixed seat 413 mounted on the slider 412. The slide rail 411 is mounted on the bracket 1 and extends axially along the winding cable 23. The fixed seat 413 is mounted on the slider 412. The groove in the slide rail 411 is a dovetail groove, the slider 412 is dovetail-shaped, and the fixed seat 413 slides on the slider 412 in a direction that moves closer to or away from the winding cable 23. Furthermore, slide rails 411 and sliders 412 are provided on both sides of the fixed seat 413 to ensure stability.

[0058] The second driving component includes a lead screw motor 421, a lead screw 422, a lead screw mounting base 413, and a widening drive block 424. The lead screw motor 421 and the lead screw mounting base 413 are both fixed on the bracket 1. One end of the lead screw 422 is connected to the lead screw motor 421, and the other end of the lead screw 422 is rotatably connected to the lead screw mounting base 413. The widening drive block 424 is disposed on the lead screw 422, and the other end of the widening drive block 424 is connected to the mounting base 413. When the lead screw motor 421 drives the lead screw 422 to rotate on the lead screw mounting base 413, the widening drive block 424 moves linearly on the lead screw 422. Specifically, the lead screw motor 421 and the lead screw fixing seat 413 are both fixed between the two slide rails 411, so that the movement of the fixing seat 413 will not be offset. The lead screw fixing seat 413 is located at the end of the bracket 1 near the winding rod 23, and the lead screw motor 421 is located at the end of the bracket 1 away from the winding rod 23. The widening drive block 424 is located on the lead screw 422. When the lead screw motor 421 drives the lead screw 422 to rotate, the widening drive block 424 drives the fixing seat 413 to move on the lead screw 422 in a direction closer to or away from the winding rod 23, and the lead screw motor 421 is located at the end away from the winding rod 23 to avoid interference between the adjustment component and the lead screw motor 421.

[0059] Furthermore, a placement opening or slot is provided on the fixed seat 413. One end of the widening drive block 424 is connected to the lead screw 422, and the other end of the widening drive block 424 is inserted into the placement opening or slot. When the widening drive block 424 moves linearly, it drives the fixed seat 413 to move closer to or further away from the first rotating wheel 22.

[0060] To ensure that the lead screw motor 421 can stop immediately when it needs to stop, thus guaranteeing the accuracy of the width, a lead screw brake 43 is provided on the lead screw motor 421. After the fixed seat 413 moves into place, the lead screw brake 43 is immediately activated, stopping the lead screw motor 421 immediately and stopping the fixed seat 413 from moving, thus ensuring the accuracy of the width.

[0061] A second connecting shaft 44 is provided on the widening blocking member. The second connecting shaft 44 is connected to the fixed base 413. When the fixed base 413 moves linearly, it drives the widening blocking member to move closer to or away from the cable rod 23, thus defining the circle width together with the first rotating wheel 22.

[0062] The widening blocking component can be configured as a blocking plate, blocking rod, blocking ring, blocking disc, or blocking arc disc, etc., as long as it can jointly define the circle width with the first rotating wheel 22. In this solution, the widening blocking component is configured as a widening rotating wheel 45.

[0063] To ensure that the cable loop width can be adjusted by changing the distance between the widening roller 45 and the first roller 22, the cable winding rod 23 needs to pass through the widening roller 45. That is, the widening roller 45 needs to be fitted around the outside of the cable winding rod 23. Therefore, a clearance opening 451 is provided on the widening roller 45. When the widening roller 45 moves toward the cable winding rod 23, the cable winding rod 23 can pass through the clearance opening 451. At the same time, the cable winding rod 23 can move within the clearance opening 451. Specifically, when the cable winding rod 23 rotates with the first roller 22, the clearance opening 451 does not interfere with the rotation of the cable winding rod 23, ensuring that the cable can be looped. When the cable winding rod 23 moves radially along the first roller 22, the clearance opening 451 does not interfere with the movement of the cable winding rod 23.

[0064] However, if the diameter of the coil is too large or too small, a single large clearance opening is insufficient. Therefore, several clearance openings 451 are provided, which are arranged radially along the widening wheel 45 in a long strip shape. The cable winding rod 23 is arranged in a one-to-one correspondence with the clearance opening 451. Of course, the number of clearance openings 451 can be equal to or greater than the number of cable winding rods 23, so that each cable winding rod 23 can be inserted into a clearance opening 451. The widening wheel 45 can move linearly along the axial direction of the cable winding rod 23 towards or away from the first wheel 22 to adjust the width of the coiled cable. When the cable winding rod 23 moves to adjust the diameter of the coiled cable, the cable winding rod 23 can move along the clearance opening 451.

[0065] Because the clearance opening 451 is elongated and each of the cable-winding rods 23 is inserted into a clearance opening 451, the widening wheel 45 needs to rotate synchronously with the first wheel 22 when the first wheel 22 rotates. Therefore, a second motor 46 is provided on the fixed base 413. The second motor 46 is connected to the second connecting shaft 44 and synchronously drives the second connecting shaft 44 to rotate. The second connecting shaft 44 synchronously drives the widening wheel 45 to rotate, and the widening wheel 45 rotates synchronously with the first wheel 22.

[0066] A distance sensor is provided at one end of the clearance opening 451 to detect the distance moved by the cable rod 23, so as to facilitate the adjustment of the loop diameter.

[0067] A widening braking assembly is provided on the second connecting shaft 44. The widening braking assembly includes a widening brake disc 47 and a widening brake element 481 for controlling the start and stop of the widening brake disc 47. The widening brake disc 47 is mounted on the second connecting shaft 44. To drive the widening brake element 481 to move closer to or away from the widening brake disc 47, a widening cylinder 48 is provided on the fixed base 413. The widening cylinder 48 includes a fixed part and a telescopic part. The fixed part is mounted on the fixed base 413, and the telescopic part is connected to the fixed part. The telescopic part can extend and retract within the fixed part, moving closer to or away from the widening brake disc 47. The widening brake element 481 is located at the end of the telescopic part near the widening brake disc 47. When the widening brake element 481 contacts the widening brake disc 47, the second connecting shaft 44 immediately stops rotating, and further, the widening wheel 45 immediately stops rotating, avoiding damage to the cable winding rod 23.

[0068] Furthermore, the second connecting shaft 44 is set to a normally open state. That is, under normal conditions, when the widening brake component 481 is not in contact with the widening brake disc 47, both the second connecting shaft 44 and the widening wheel 45 remain in a rotating state. After the widening brake component 481 contacts the widening brake disc 47, the second connecting shaft 44 immediately stops rotating, and simultaneously causes the widening wheel 45 to immediately stop rotating.

[0069] A cylindrical electric slide rail 441 is provided on the second connecting shaft 44, and a slip ring fixing seat 49 is provided on the fixing seat 413. An electric slip ring is provided on the slip ring fixing seat 49. The electric slip ring contacts the cylindrical electric slide rail 441, so that the rotation of the second connecting shaft 44 will not be deflected. At the same time, the electric slip ring energizes the second connecting shaft 44, avoiding the cable from getting tangled on the second connecting shaft 44 when using a cable for energizing.

[0070] The process of coiling cables: The first electromagnetic brake is activated, causing the first motor 24 to be off and the first rotating wheel 22 to stop rotating; the first cylinder drives the first brake element 36 to move towards the first brake disc 37 and contact the first brake disc 37, causing the first connecting shaft 31 to stop rotating; the widening cylinder 48 drives the widening brake element 481 to move towards the widening brake disc 47 until the widening brake element 481 contacts the widening brake disc 47, causing the second connecting shaft 44 to stop rotating and the widening rotating wheel 45 to stop rotating; the lead screw motor 421 stops operating, and the fixed seat 413 remains stationary. Insert one end of the cable into the U-shaped groove 231 to lock the cable head in the groove and prevent it from coming loose, and then start the coiling module 2; The first electromagnetic brake is deactivated, the first motor 24 is activated, the first rotating wheel 22 begins to rotate, and the winding rod 23 rotates accordingly; the first cylinder drives the first brake element 36 to move away from the first brake disc 37, causing the first brake element 36 to separate from the first brake disc 37, and the first connecting shaft 31 begins to rotate; the widening cylinder 48 drives the widening brake element 481 away from the widening brake disc 47, causing the widening brake element 481 to separate from the widening brake disc 47, and the second connecting shaft 44 begins to rotate; the lead screw motor 421 is deactivated. As the cable rod 23 rotates, combined with the external cable routing device, the cable is arranged tightly and orderly layer by layer on the coiling frame formed by several cable rods 23; after the coiling is completed, the cable is cut to the required length and the end of the cable is tied, and the coiling is completed.

[0071] The process of cable disassembly: After the loop is completed, the cable is cut to the required length and the end of the cable is tied. Then, the first electromagnetic brake is activated, the first braking component 36 contacts the first brake disc 37, and the widening braking component 481 contacts the widening brake disc 47, so that the first rotating wheel 22, the first connecting shaft 31 and the second connecting shaft 44 all stop rotating. The lead screw motor 421 starts, driving the fixed seat 413 to move away from the first rotating wheel 22, further causing the widening rotating wheel 45 to move away from the first rotating wheel 22, until the cable winding rod 23 disengages from the widening rotating wheel 45, making it easier to disassemble the coiled cable; When the first electromagnetic brake is closed, the first rotating wheel 22 rotates in the opposite direction to when it is forming a coil. If it rotates clockwise when forming a coil, it rotates counterclockwise when disassembling. At this time, the reducing nut 321 moves toward the direction closer to the first rotating wheel 22, and the connecting rod 323 begins to rotate around the first hinge and / or the second hinge 324, causing the cable winding rod 23 to contract toward the direction closer to the first connecting shaft 31. The distance from the axis of the first connecting shaft 31 becomes smaller, and the outer diameter of the cable that can be wound will shrink, causing the cable coil to change from a tensioned state to a loose state on the cable winding rod 23. Insert the binding rope into the sufficient space between several cable rods 23 and secure the cable loop. Then the cable loop can be easily removed. At the same time, the cable end inserted before the cable loop is wound will slide out from the U-shaped groove 231 of the cable rod 23, thus achieving cable disassembly.

[0072] Variable diameter working process: The first cylinder drives the first brake member 36 to move toward the first brake disc 37 and to contact the first brake disc 37, so that the first connecting shaft 31 remains in a non-rotating state. To adjust the diameter as needed, the first motor 24 can be operated to rotate forward, not rotate, or rotate in reverse. Taking normal loop formation as an example, if the diameter to be adjusted is larger than the current loop diameter, the first motor 24 rotates forward; if the diameter to be adjusted is equal to the current loop diameter, the first motor 24 does not rotate; if the diameter to be adjusted is smaller than the current loop diameter, the first motor 24 rotates in reverse. If the end of the cable 23 near the widening wheel 45 is inserted into the clearance opening 451, the widening wheel 45 will rotate with the first wheel 22. The rotation of the widening wheel 45 is synchronous and in the same direction as the first wheel 22. If the end of the cable 23 near the widening wheel 45 is not inserted into the clearance opening 451, the widening wheel 45 can stop rotating when the first wheel 22 rotates.

[0073] Widening process: The first electromagnetic brake remains in the open state, keeping the first motor 24 in the closed state and the first rotating wheel 22 in a non-rotating state; the first cylinder drives the first brake member 36 to move towards the first brake disc 37 and contact the first brake disc 37, keeping the first connecting shaft 31 in a non-rotating state; the widening cylinder 48 drives the widening brake member 481 to move towards the widening brake disc 47 until the widening brake member 481 contacts the widening brake disc 47, causing the second connecting shaft 44 to stop rotating, further keeping the widening rotating wheel 45 in a non-rotating state; Depending on the required width, the lead screw motor 421 can be operated to rotate forward, not rotate, or rotate in reverse. Taking moving towards the first rotating wheel 22 as an example, if the required width is greater than the current loop width, the lead screw motor 421 rotates in reverse, and the widening rotating wheel 45 moves away from the first rotating wheel 22. If the required width is equal to the current loop width, the lead screw motor 421 does not rotate. If the required width is less than the current loop width, the lead screw motor 421 rotates in reverse, and the widening rotating wheel 45 moves towards the first rotating wheel 22.

[0074] This device can be connected to an external control system, including but not limited to PLC control. By inputting the required diameter and width into the PLC, the PLC can automatically control the device to adjust.

[0075] To achieve automation, a sensor can be set at the corresponding position on the bracket 1 as a width marker. When the fixed base 413 reaches the width marker, the width of the cable loop is the set width. When the width needs to be adjusted, the required width is input to the control system. The control system drives the first electromagnetic brake to stop the first motor 24, the first wheel 22 stops rotating, drives the first brake element 36 to stop the first brake disc 37, the first connecting shaft 31 stops rotating, drives the widening brake element 481 to stop the widening brake disc 47, and the second connecting shaft 44 stops rotating. The sensor sends a signal to the control system to inform it of the position of the fixed seat, or the control system sends a signal to the lead screw motor 421 to control the fixed seat 423 to reach the width mark point. Based on the required width and the position of the fixed seat 423, the lead screw motor 421 is driven to rotate forward or backward, causing the widening wheel 45 to move towards or away from the first wheel 22. A distance sensor is installed on the clearance opening 451 as a diameter marker point. When the cable reaches the diameter marker point after winding around the cable rod 23, the diameter of the cable loop is the set diameter. When the diameter needs to be adjusted, the required diameter is input to the control system. The control system drives the first brake 36 to stop the first brake disc 37 and the first connecting shaft 31 to stop rotating. The distance sensor sends a signal to the control system to inform it of the current position of the cable rod 23. Based on the required adjustment width and the position of the cable rod 23, the first motor 24 rotates forward or in reverse, causing the cable rod 23 to move radially along the first rotating wheel 22.

[0076] The control system is electrically connected to all modules, sensors, braking components, motors, and brakes in this solution to ensure automatic and precise control.

[0077] In summary, by setting a variable diameter structure, the circumference formed by the cable rod 23 can be set to any diameter. The widening module 4 allows for arbitrary adjustment of the distance between the adjusting component and the first rotating wheel 22 to achieve any width. By incorporating a braking element or brake, the motor can be stopped immediately when needed, ensuring the accuracy of diameter and width changes. The tension adjusting structure 33 and tension wheel 30 further guarantee precise diameter changes.
