Technical Field

[0001] This invention relates to the field of winding equipment technology, and in particular to a winding device and winding process for an anti-ultraviolet cable packaging film. Background Technology

[0002] Cables are core infrastructure for power transmission and communication networks, widely used in power grids, rail transit, new energy power plants, and outdoor engineering projects. From manufacturing to installation, cables often require long-term warehousing, long-distance transportation, and temporary outdoor storage. The outer packaging directly determines the cable's insulation performance, mechanical strength, and service life. With the development of new power systems, ultra-high voltage power transmission, and photovoltaic / wind power industries, the outdoor and long-term applications of cables are increasing, placing stringent requirements on packaging films for long-lasting UV resistance, high weather resistance, and high reliability. Industry standards such as those of the State Grid Corporation of China have clearly stipulated that outer packaging films must pass more than 1000 hours of accelerated UV aging testing. Ordinary films no longer meet compliance and practical requirements, making UV-resistant cable packaging films an industry necessity. This film uses PE as the base material and is compounded with functional components such as UV absorbers and hindered amine light stabilizers (HALS). It can absorb / quench UV energy, inhibit polymer degradation, significantly improve weather resistance, and provide stable protection for the entire cable storage and transportation process, while also aligning with power material safety standards and green and low-carbon trends.

[0026] The positioning assembly 33 includes a lead screw 331, a slider 332, a connecting body 333, two push plates 334, and a rotating wheel 335. A groove 21 is provided on the power housing 2.

The slider 332 is made of nylon and has a graphite copper sleeve embedded in its surface to reduce the coefficient of friction with the groove 21. The rotating wheel 335 is fixedly connected to the lead screw 331. The rotating wheel 335 is a handwheel structure with a non-slip rubber sleeve on its surface for easy manual adjustment. The lead screw 331 is rotatably connected to the power housing 2. The slider 332 is screwed to the lead screw 331. When the lead screw 331 rotates, it drives the slider 332 to move back and forth along the slide groove 21. The connecting body 333 is fixedly connected to the slider 332. The connecting body 333 is a U-shaped connector and is fastened to the slider 332 by bolts. One end of the two push plates 334 is rotatably connected to the connecting body 333.

The rotation angle range of the push plates 334 is 0-60°, which can be adapted to different movement angles of the adjusting shafts 311 to achieve bidirectional tension adjustment.

[0027] The winding module 4 also includes a second transmission belt 43, with its two ends connected to the drive rod 321 and the drive shaft 41 respectively. The second transmission belt 43 is a synchronous toothed belt, meshing with the synchronous pulley of the drive rod 321 and the winding roller connecting shaft of the drive shaft 41, with a transmission ratio of 1:2. It can transmit the power of the drive assembly 32 to the winding module 4, driving the winding roller to rotate and realize the winding of the film material. The tension of the second transmission belt 43 is adjusted by an adjustable tensioning wheel to ensure transmission efficiency.

[0028] The limiting assembly 42 includes an adaptive limiting rod 421, a second slider 422, and a first spring 423. The adaptive limiting rod 421 is slidably connected to the power housing 2, and the sliding direction of the adaptive limiting rod 421 is perpendicular to the axis of the drive shaft 41. The second slider 422 is fixedly connected to the adaptive limiting rod 421 and slides in conjunction with the guide groove of the power housing 2. The two ends of the first spring 423 are fixedly connected to the adaptive limiting rod 421 and the power housing 2, respectively. The first spring 423 is a tension spring. When the winding diameter of the cable packaging film reaches the preset maximum diameter, the limiting assembly 42 will trigger the switching assembly.

[0029] The switch assembly 44 includes a bidirectional contactor 441 and a trigger button 442. The bidirectional contactor 441 is slidably connected to the power housing 2, and its sliding stroke is 0-50mm. It can realize the forward and reverse rotation, start and stop of the motor 6, and start and stop control of the cutting assembly 5. The contacts of the bidirectional contactor 441 are made of silver alloy material, which has the properties of high temperature resistance and arc resistance. The trigger button 442 is fixedly connected to the power housing 2 and electrically connected to the motor 6 and the cutting assembly 5.

[0030] The cutting assembly 5 includes a safety housing 51, a second motor 52, a second drive shaft 53, a first power gear 54, a second power gear 55, a third power gear 56, a second lead screw 57, a moving block 58, a loading chamber 59, a second spring 591, and a blade 592.

The second drive shaft 53 is fixedly connected to the second motor 52 and rotatably connected to the second power housing 2. The first power gear 54 is fixedly connected to the second drive shaft 53, and has 24 teeth and a module of 2. The second power gear 55 meshes with the first power gear 54, and has 36 teeth. The third power gear 56 meshes with the second power gear 55 and is coaxially and fixedly connected to the second lead screw 57, and has 18 teeth. Precise speed control is achieved through a three-stage gear transmission with a transmission ratio of 1:3. Lead screw 57 is rotatably connected to safety housing 51. Both ends of lead screw 57 are rotatably engaged with the mounting base of safety housing 51 via thrust ball bearings. Moving block 58 is screwed to lead screw 57. A nut seat is embedded inside moving block 58, engaging with lead screw 57. The sliding stroke of moving block 58 is 0-150mm, enabling reciprocating movement of loading chamber 59. Loading chamber 59 is fixedly connected to moving block 58. Both ends of spring 591 abut against loading chamber 59 and blade 592, respectively. Blade 592 abuts against safety housing 51. When cutting is required, motor 2 52 drives power gear 1 54 to rotate, which in turn drives power gear 2 55 to rotate, and then transmits the force to power gear 3 56, which in turn drives lead screw 2 57 to rotate, so that moving block 58 can move up and down on lead screw 2 57. When moving block 58 moves to the preset position, blade 592 separates from safety housing 51 and is ejected from safety housing 51 under the action of spring 2 591, and then contacts cable packaging film and continues to move to achieve the purpose of cutting cable packaging film.

[0031] In summary, the working principle of a winding device for UV-resistant cable packaging film is described below: After startup, motor 6 achieves precise speed and torque output, transmitting power to the two drive rods 321 of drive assembly 32 via two synchronous toothed drive belts. One drive rod 321 drives the reversing gear set 314 of tension adjustment system 3 via the synchronous toothed drive belt. The reversing gear set 314 transmits power to adjustment shaft 311 through the meshing of outer ring gear 3141, transmission gear 3142 and inner ring gear 3143. At the same time, rotating the handwheel 335 of positioning assembly 33 drives lead screw 331 to rotate, causing slider 332 to reciprocate along the "+" shaped slide groove 21 of power housing 2. A drive rod 332 drives an aluminum alloy push plate 334 to swing, which in turn pushes two adjusting shafts 311 to slide along the guide rail pair. This, in conjunction with the guide wheel 34, prevents film deflection and scratching during winding and allows for quick replacement of the guide wheel 34 according to the film width. Simultaneously, it achieves bidirectional and precise adjustment of the film tension. The pressure sensor embedded in the adjusting shaft 311 can also monitor tension changes in real time, providing feedback for adjustment. Another drive rod 321 drives a drive shaft 41 to rotate via a transmission belt 43. The drive shaft 41 drives the winding roller to rotate, completing the continuous winding of the UV-resistant cable packaging film. As the film winding diameter increases, the outer wall of the film roll will push up a limit. The adaptive limit rod 421 of component 42 causes the slider 2 422 to slide along the guide groove of the power housing 2 and stretch the spring 1 423. When the winding diameter reaches the preset maximum value, the displacement of the adaptive limit rod 421 will trigger the switch component 44. After the bidirectional contactor 441 of the switch component 44 is triggered, on the one hand, the power supply of the servo motor 1 6 is cut off to automatically stop the device, and on the other hand, a start signal is sent to the cutting component 5. After the trigger key 442 is energized, the motor 2 52 starts and drives the drive shaft 2 53 to rotate. Through the three-stage gear transmission composed of the power gear 1 54, the power gear 2 55, and the power gear 3 56, the speed is precisely adjusted. The control system transmits power to the lead screw 57, which rotates in conjunction with the safety housing 51. The rotation of the lead screw 57 causes the moving block 58, which has an embedded nut seat inside, to slide axially. The moving block 58 causes the loading chamber 59 to move synchronously. When the moving block 58 reaches the preset cutting position, the blade 592 disengages from the contact limit of the safety housing 51 and is ejected from the safety housing 51 by the elastic force of the spring 591. After contacting the cable packaging film, it continues to move with the moving block 58 to complete the film cutting. After the cutting is completed, the motor 52 reverses, causing the lead screw 57, the moving block 58, the loading chamber 59, and the blade 592 to reset. The device completes the entire process of a single winding and cutting.

[0032] This invention also provides a winding process for an anti-UV cable packaging film, comprising: The overall operation program of the starting device is initiated. Motor 6 starts and outputs precise speed and torque, transmitting power synchronously to the two drive rods 321 of the drive assembly 32 via two synchronous toothed drive belts, providing the power foundation for subsequent winding and tension adjustment. The initial position confirmation of each component of the device is completed simultaneously: the tension adjustment system 3, positioning assembly 33, winding drive assembly, limiting assembly 42, and cutting assembly 5 are all in their initial working state, ready for the winding process.

[0033] Two drive rods 321 perform different transmission tasks. One drive rod 321 drives the reversing gear set 314 of the tension adjustment system 3 via a synchronous toothed transmission belt; the other drive rod 321 drives the drive shaft 41 to rotate via a second transmission belt 43. After the drive shaft 41 rotates, it directly drives the winding roller to rotate. The UV-resistant cable packaging film enters the winding roller along a preset path. The continuous rotation of the winding roller realizes the continuous winding of the film material, providing the core power for film forming.

[0034] After receiving power from the drive rod 321, the reversing gear set 314 transmits power precisely to the adjusting shaft 311 through the meshing of the outer ring gear 3141, the transmission gear 3142, and the inner ring gear 3143, providing a transmission basis for the displacement of the adjusting shaft. Rotating the handwheel 335 of the positioning assembly 33 drives the lead screw 331 to rotate, causing the slider 332 to reciprocate linearly along the "+" shaped groove 21 of the power housing 2; when the slider 332 moves, it drives the aluminum alloy push plate 334 to swing, thereby pushing the two adjusting shafts 311 to slide along the guide rail pair.

[0035] During the sliding process of the adjusting shaft 311, it works with the guide wheel 34 to achieve dual functions: first, to limit the offset and scratching of the membrane material during winding, ensuring the flatness of the winding; second, to allow the guide wheel 34 to be quickly replaced according to the actual width of the membrane material, adapting to different specifications of membrane material; at the same time, the pressure sensor embedded in the adjusting shaft 311 monitors the changes in membrane material tension in real time, and feeds the data back to the adjusting system to achieve bidirectional and precise adjustment of membrane material tension.

[0036] As the membrane winding diameter increases, the outer wall of the membrane roll gradually pushes up the adaptive limit rod 421 of the limiting component 42, causing the slider 422 to slide along the guide groove of the power housing 2 and stretch the spring 423. When the winding diameter reaches the preset maximum value, the displacement of the adaptive limit rod 421 triggers the switch component 44. After the bidirectional contactor 441 of the switch component 44 is triggered, it executes two commands: first, it cuts off the power to the servo motor 6, causing the winding device to stop automatically and preventing over-winding of the membrane; second, it sends a start signal to the cutting component 5, energizing the trigger key 442. After the trigger key 442 is energized, the motor 52 starts, driving the drive shaft 53 to rotate. The power is precisely adjusted through a three-stage gear transmission group consisting of the power gear 54, the power gear 55, and the power gear 56, and then transmitted to the lead screw 57 that rotates with the safety housing 51.

[0037] The rotation of the lead screw 57 drives the moving block 58, which has an internally embedded nut seat, to slide axially. The moving block 58 simultaneously drives the loading chamber 59 to move. When the moving block 58 reaches the preset cutting position, the blade 592 disengages from the abutment limit of the safety housing 51 and pops out of the safety housing 51 under the elastic force of the spring 591. After the blade pops out, it contacts the cable packaging film and continues to move with the moving block 58 to complete the precise cutting of the film material.

[0038] After the cutting is completed, motor 2 52 executes the reverse command, which drives drive shaft 2 53 to rotate in the opposite direction. Through the three-stage gear transmission group, it drives lead screw 2 57 to reverse, thereby driving moving block 58, loading chamber 59 and blade 592 to return to the initial position along the axis. The cutting assembly returns to standby state, completing the closed loop of a single winding and cutting process.

By driving the reversing gear set (314), and then driving the drive shaft (41) to rotate through the transmission belt (43), the winding roller rotates, and the film material enters along the preset path and is continuously wound. After receiving power, the reversing gear set (314) transmits the power to the adjusting shaft (311) through gear meshing; rotating the rotating wheel (335) drives the lead screw (331) to rotate, causing the slider (332) to move along the cross-shaped groove (21) of the power housing (2), and then pushes the two adjusting shafts (311) to slide along the guide rail pair through the push plate (334); when the adjusting shaft (311) slides, it cooperates with the guide wheel (34) to adjust the tension; When the diameter of the membrane roll increases, the membrane roll lifts the adaptive limit rod (421) of the limiting component (42), causing the second slider (422) to slide and stretch the first spring (423); when the winding diameter reaches the preset maximum value, the adaptive limit rod (421) triggers the switch component (44).
