Description

Technical Field

[0001] This invention relates to the field of cable processing technology, specifically to a cable processing equipment and a cable processing method. Background Technology

[0002] In the field of cable manufacturing, ultraviolet irradiation crosslinking is a key process to improve the heat resistance, mechanical strength and electrical properties of rubber insulation materials. It generates free radicals by stimulating the photoinitiator inside the material with ultraviolet light, which promotes the formation of a three-dimensional network crosslinked structure of linear polymer chains, thereby significantly improving the overall performance of cable products.

[0003] For example, an existing patent (publication number: CN223967070U) discloses an irradiation rubber cable processing equipment and cable processing method, relating to the field of cable production technology. This utility model includes an irradiation box, inside which a rotating assembly is arranged. An irradiation assembly is located at the rotating end of the rotating assembly. A driving assembly is located on one side of the rotating assembly, and the driving assembly is power-connected to the rotating end of the rotating assembly. By passing a cable through the interior of the irradiation box and causing it to move continuously inside the box under the drive of a winding device, the driving assembly drives the rotating assembly, causing the irradiation assembly to rotate on the outside of the cable. Since the irradiation assembly has a certain length, the ultraviolet rays emitted by the irradiation assembly can evenly irradiate the outer surface of the cable. This arrangement ensures a relatively uniform distribution of radiation energy on the cable surface, thereby guaranteeing the quality of cable irradiation.

[0004] However, when the above-mentioned devices are used, the fixed irradiation structure with a single ultraviolet lamp results in a generally poor irradiation effect, making it difficult to guarantee the stability of product quality. At the same time, existing equipment generally does not have an effective cable centering and guiding mechanism. During continuous traction and transportation, the cable is prone to radial deviation, vertical movement, or swinging, and cannot always be kept in the center position of the irradiation area. This causes the distance between the cable surface and the ultraviolet lamp to change randomly, further aggravating the problem of uneven irradiation dose and seriously affecting the consistency of processing.

[0005] Therefore, a cable processing equipment and cable processing method are proposed to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a cable processing equipment and a cable processing method to solve the problems mentioned in the background art.

A second mounting bracket is fixedly installed at the end of the second transmission rod. A centering roller is rotatably installed in the second mounting bracket. The irradiation lamp, the centering roller, and the cable are parallel. A first transmission groove corresponding to the first transmission rod and a second transmission groove corresponding to the second transmission rod are opened in the adjustment disc. The first transmission rod can slide along the first transmission groove, and the second transmission rod can slide along the second transmission groove.

[0010] Preferably, the first transmission groove and the second transmission groove are staggered, and both the first transmission groove and the second transmission groove are arranged in an oblique structure.

[0011] Preferably, the control mechanism includes a slide groove, which is formed on an adjusting circular frame. An incomplete worm gear plate is slidably installed in the slide groove. The incomplete worm gear plate is fixedly connected to the outer edge of the adjusting disc. A worm is also rotatably installed on the adjusting circular frame via a shaft bracket. The incomplete worm gear plate meshes with the worm. An operating knob is fixedly connected to one end of the worm.

[0013] Preferably, the inlet and outlet ends of the sealed control cabinet are equipped with sealing and dustproof components. The sealing and dustproof components include an internal thread and a threaded disc. The internal thread and the threaded disc are detachably threaded. The inner side of the threaded disc is provided with a sealing sponge, and the outer side of the threaded disc is also concentrically fixed with a toothed disassembly ring.

[0014] Preferably, the sealed control cabinet is further equipped with a dust removal component, which includes a fixing rod. A circulating air nozzle is fixedly connected to one side of the inner cavity of the sealed control cabinet via the fixing rod. An air hole is provided on the inner side of the circulating air nozzle. A circulating pump is fixedly installed on the sealed control cabinet. The input end of the circulating pump is connected to the circulating air nozzle via a first hose. The output end of the circulating pump is detachably connected to a collection box. The end of the collection box away from the circulating pump is connected to the other side of the inner cavity of the sealed control cabinet via a second hose. A dust filter screen is provided inside the collection box.

[0015] Preferably, the circulating air nozzle is concentrically arranged with the inner ring plate, and the irradiation lamp and centering roller are both located inside the circulating air nozzle.

[0016] A cable processing method includes the following steps:

[0017] S1. Pre-processing: Adjust the radial positions of the irradiation lamp and the centering roller according to the outer diameter specifications of the cable to be processed; rotate the worm gear through the control mechanism to drive the incomplete worm wheel plate to slide along the slide groove, thereby driving the adjustment disk to rotate in the adjustment frame. When the adjustment disk rotates, the first transmission groove drives the first transmission rod to slide radially along the first frame plate, simultaneously adjusting the radial position of each irradiation lamp. At the same time, the second transmission groove drives the second transmission rod to slide radially along the second frame plate, simultaneously adjusting the radial position of each centering roller, so that the inner diameter of the centering roller is matched with the outer diameter of the cable, and the distance between the irradiation lamp and the surface of the cable reaches the preset irradiation distance. After the adjustment is completed, the position of the adjustment disk is locked by the self-locking characteristics of the worm gear and the incomplete worm wheel plate.

[0018] S2. Cable threading and centering: The cable to be processed is threaded through the sealed dustproof assembly at one end of the sealed control cabinet, then through the inner ring plate and the inside of the circulating air nozzle in sequence, and out through the sealed dustproof assembly at the other end of the sealed control cabinet. The end of the cable is then connected to the winding device. After threading, the centering rollers distributed around the circumference are attached to the outer surface of the cable to limit and keep the cable in the center position concentric with the inner ring plate, thus completing the cable centering and positioning.

[0019] S3. Irradiation processing parameter setting: Start the irradiation lamp to complete the preheating. Set the ultraviolet irradiation parameters according to the material characteristics and thickness of the insulation layer of the cable to be processed. At the same time, start the drive motor. The drive motor drives the spur gear to rotate. Through the meshing transmission of the spur gear ring, it drives the inner ring plate to rotate. Then, through the connecting rod, it drives the circumferentially distributed irradiation lamps and centering rollers to rotate synchronously around the cable as the axis. Set the rotation speed of the inner ring plate to match the traction and winding speed of the cable.

[0020] S4. Sealing and dust prevention and internal cavity purification: After the cable is threaded through, the threaded disc containing sealing sponge is installed at the inlet and outlet ends of the sealed control cabinet through the threaded engagement of the threaded disc and the internal thread, so that the sealing sponge adheres to the outer surface of the cable to form a sealed barrier; at the same time, the circulation pump is started. The circulation pump draws dust-laden gas from the inner cavity of the sealed control cabinet through the air hole of the circulation air nozzle, and delivers it to the collection box through the first hose. After being filtered and removed by the dust filter screen, the clean gas flows back to the inner cavity of the sealed control cabinet through the second hose, forming a circulating airflow for purification and continuously maintaining the cleanliness of the inner cavity;

[0021] S5. Continuous irradiation processing: Start the winding device to drive the cable through the irradiation processing area of ​​the sealed control cabinet at a preset speed. Multiple sets of irradiation lamps rotating in the circumferential direction continuously and uniformly irradiate the outer surface of the cable from 360 degrees, so that the cable insulation material completes the cross-linking reaction.

[0022] S6. After processing is completed, turn off the winding device, drive motor, irradiation lamp and circulation pump in sequence. After the irradiation lamp cools down, take the processed cable out of the equipment to complete the cable irradiation processing.

[0023] Beneficial effects

[0024] Compared with the prior art, the present invention provides a cable processing equipment and a cable processing method, which have the following beneficial effects:

[0025] 1. This invention uses multiple sets of irradiation lamps evenly distributed around the circumference of the cable, and in conjunction with a uniform irradiation component to drive the irradiation lamps to rotate synchronously around the cable as the axis. Compared with the existing single-lamp rotating irradiation structure, it achieves 360° continuous irradiation without dead angles from multiple light sources, fundamentally eliminating the irradiation energy gradient in the circumference of the cable, avoiding the problems of insufficient or excessive cross-linking in some areas, significantly improving the uniformity of irradiation dose on the cable surface, ensuring the stability of key indicators such as thermal elongation and withstand voltage performance of the insulation layer, and significantly improving the processing quality and finished product qualification rate of cable products.

[0026] 2. This invention uses multiple sets of centering rollers arranged in a staggered circumference with the irradiation lamp to fully adhere to the outer surface of the cable during the irradiation process, limiting the cable from multiple directions and keeping it stably in the center position concentric with the inner ring plate. This effectively avoids radial offset, slippage, or swaying problems that occur during continuous traction and transportation of the cable, ensuring a constant distance between the cable surface and the irradiation lamp, further improving the consistency of irradiation dose and processing stability, and filling the technical gap of existing equipment without a synchronous centering mechanism.

[0027] 3. This invention, by setting a distance adjustment component, allows for the synchronous adjustment of the radial position of the irradiation lamp and the centering roller through a single set of control mechanisms, adapting to the processing needs of cables with different outer diameter specifications. The worm gear and the incomplete worm wheel plate meshing drive the adjustment disc to rotate. Utilizing the first and second transmission grooves with oblique structures, multiple sets of first and second transmission rods can be synchronously driven to extend and retract radially, achieving high adjustment precision. Furthermore, after adjustment, the self-locking characteristic of the worm gear automatically locks the position, preventing displacement during processing. Simultaneous synchronous adjustment of the irradiation lamp and the centering roller ensures they are always in a suitable relative position, balancing centering effect with precise control of the irradiation distance, significantly improving the equipment's versatility and ease of operation.

[0028] 4. This invention, by installing a sealing and dustproof component at the inlet and outlet of the enclosed control cabinet, utilizes the sealing sponge inside the threaded disc to form a flexible seal against the outer surface of the cable. This not only does not affect the axial movement of the cable but also effectively isolates the internal irradiation environment from dust, impurities, and temperature and humidity fluctuations in the external environment. This avoids the problems of reduced irradiation efficiency and hindered photochemical reactions caused by dust adhering to the surface of the irradiation lamp or cable. Simultaneously, in conjunction with the closed-loop circulating airflow purification structure of the dust removal component, the internal gas is circulated by a circulating pump. The dust is continuously filtered and removed from the internal cavity by the dust filter screen in the collection box, further maintaining the cleanliness of the irradiation cavity, ensuring the stability of the irradiation effect during long-term operation, reducing processing defects, and meeting the needs of continuous and large-scale production of high-quality rubber cables.

[0029] 5. The invention has a compact overall structure, integrating functions such as cable centering, irradiation spacing adjustment, uniform irradiation, and environmental protection into one unit. The irradiation lamp and the centering roller rotate and adjust synchronously, and the centering and irradiation processes are completed in one integrated manner. The processing flow is continuous, the equipment is easy to operate, and it can be adapted to the batch continuous processing of cables of different specifications. The equipment modification cost is low, and it can be directly connected to existing cable production lines, which has good promotion and application value. Attached Figure Description

[0044] 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.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0046] Example 1, please refer to Figures 1 to 6 As shown:

[0047] To address the problems mentioned in the technical solutions, this application provides a cable processing equipment and a cable processing method, including a sealed control cabinet 1. The sealed control cabinet 1 is a horizontal hollow cavity structure that provides a closed processing environment for cable irradiation processing. Support legs 2 are fixedly installed at the four corners of the bottom of the sealed control cabinet 1 to provide stable support for the entire equipment. A switch plate 3 is provided on the support leg 2. A handle 4 is fixedly installed on the front side of the switch plate 3. The switch plate 3 is rotatably installed between the two sets of support legs 2 via a hinge and is used to place electrical components related to equipment control, facilitating maintenance and parameter operation by operators.

[0048] Both ends of the inlet and outlet of the sealed control cabinet 1 are concentrically mounted with inner ring plates 5. The two inner ring plates 5 are fixedly connected by multiple connecting rods 6 evenly distributed around the circumference. The two inner ring plates 5 and the connecting rods 6 together form an integrated rotating frame, providing a stable mounting base for the irradiation lamps 7 and the centering rollers 8. At least two irradiation lamps 7 are evenly distributed around the circumference between the two inner ring plates 5. In this embodiment, four sets of irradiation lamps 7 are provided, evenly distributed around the circumference at ninety degrees. The irradiation lamps 7 are ultraviolet mercury lamps or ultraviolet LED lamps, used to emit ultraviolet light to complete the irradiation crosslinking of the cable insulation layer; the two inner ring plates Centering rollers 8, the same number as the irradiation lamps 7, are evenly distributed circumferentially between the 5. The centering rollers 8 are staggered with the irradiation lamps 7, that is, a set of centering rollers 8 is set between every two adjacent irradiation lamps 7. The centering rollers 8 are made of high temperature resistant and UV aging resistant silicone rollers. The roller surface is flexibly attached to the outer surface of the cable to keep the cable in a concentric positioning state with the inner ring plate 5 and prevent the cable from radially deviating during the traction process. The sealed control cabinet 1 is also equipped with a uniform irradiation component 10. The uniform irradiation component 10 is used to control the irradiation lamps 7 and the centering rollers 8 to rotate synchronously around the cable to achieve 360° uniform irradiation.

[0049] Furthermore, a distance adjustment assembly 9 is provided on the irradiation lamp 7 and the centering roller 8 to synchronously adjust the radial position of the irradiation lamp 7 and the centering roller 8, adapting to the processing of cables with different outer diameter specifications. The distance adjustment assembly 9 includes an adjustment frame 91, which is fixedly installed between the connecting rods 6 and is concentrically arranged with the inner ring plate 5. An adjustment disc 92 is rotatably mounted on the inner side of the adjustment frame 91 via a bearing, and the adjustment disc 92 can rotate freely around the concentric axis within the adjustment frame 91. A control mechanism 93 is provided on the adjustment frame 91 to drive the adjustment disc 92 to rotate and achieve position locking.

[0050] A first frame plate 94, the same number as the number of irradiation lamps 7, is fixedly installed between the two inner ring plates 5. The first frame plate 94 is fixedly set radially along the adjusting round frame 91. A radial guide hole is opened on the first frame plate 94. The first transmission rod 95 is linearly slidably installed along the radial direction of the adjusting round frame 91 through the guide hole. A first mounting bracket 96 is fixedly installed on the end of the first transmission rod 95 facing the cable. The irradiation lamps 7 are fixedly installed in the first mounting bracket 96 by bolts. The radial sliding of the first transmission rod 95 drives the irradiation lamps 7 to move synchronously in the radial direction, thereby adjusting the irradiation distance between the irradiation lamps 7 and the cable surface.

[0051] A second frame plate 97, the same number as the centering rollers 8, is fixedly installed between the two inner ring plates 5. The second frame plate 97 is fixedly arranged radially along the adjusting round frame 91. A radial guide hole is opened on the second frame plate 97. The second transmission rod 98 is linearly slidably installed along the radial direction of the adjusting round frame 91 through the guide hole. A second mounting bracket 99 is fixedly installed at the end of the second transmission rod 98 facing the cable. The centering rollers 8 are rotatably installed in the second mounting bracket 99 through bearings. By sliding the second transmission rod 98 radially, the centering rollers 8 are driven to move synchronously radially, adjusting the encircling inner diameter of multiple sets of centering rollers 8 to adapt to cables with different outer diameters.

[0052] The irradiation lamp 7 and the centering roller 8 are both parallel to the cable, ensuring that the irradiation range of the irradiation lamp 7 and the limiting range of the centering roller 8 are consistent with the axial movement direction of the cable, thus ensuring the continuity and stability of irradiation and centering during processing. The adjusting plate 92 has a first transmission groove 911 corresponding to the first transmission rod 95 and a second transmission groove 912 corresponding to the second transmission rod 98. A sliding column is fixed at the end of the first transmission rod 95 away from the cable. The sliding column is embedded in the first transmission groove 911 and can slide along the first transmission groove 911. A sliding column is fixed at the end of the second transmission rod 98 away from the cable. The sliding column is embedded in the second transmission groove 912 and can slide along the second transmission groove 912.

[0053] Furthermore, the first transmission groove 911 and the second transmission groove 912 are staggered to avoid motion interference between the first transmission rod 95 and the second transmission rod 98 during transmission. Both the first transmission groove 911 and the second transmission groove 912 are arranged with oblique lines. The oblique transmission groove can convert the circumferential rotation of the adjusting disk 92 into the radial linear displacement of the first transmission rod 95 and the second transmission rod 98 when the adjusting disk 92 rotates. The tilt angle and spiral direction of the multiple sets of first transmission grooves 911 are completely consistent, and the tilt angle and spiral direction of the multiple sets of second transmission grooves 912 are completely consistent, ensuring that the multiple sets of irradiation lamps 7 and multiple sets of centering rollers 8 synchronously extend and retract radially during the adjustment process, and always maintain a concentric circumferential distribution.

[0054] Furthermore, the control mechanism 93 includes a slide 931, which is an arc-shaped through groove formed on the side wall of the adjusting frame 91. The slide 931 is concentrically arranged with the adjusting frame 91. An incomplete worm gear plate 932 is slidably installed in the slide 931. The bottom surface of the incomplete worm gear plate 932 is fixedly connected to the outer edge of the adjusting plate 92. A worm 934 is also rotatably installed on the adjusting frame 91 via two sets of shaft brackets 933. The worm gear teeth on the outer edge of the incomplete worm gear plate 932 mesh with the worm 934. One end of the worm 934 is fixedly connected to an operating knob 935. Rotating the operating knob 935 drives the worm 934. The rotation of the worm gear 934, through meshing transmission, drives the incomplete worm gear plate 932 to slide along the slide groove 931, ultimately driving the adjustment disk 92 to rotate, thus completing the radial position adjustment of the irradiation lamp 7 and the centering roller 8. At the same time, the meshing structure of the worm 934 and the incomplete worm gear plate 932 has a reverse self-locking characteristic, that is, the incomplete worm gear plate 932 can only be driven to rotate by the worm 934, and the incomplete worm gear plate 932 cannot drive the worm 934 to rotate in the reverse direction. This ensures that after the adjustment is completed, the position of the adjustment disk 92 is stably locked and will not be displaced by vibration during the processing, thus ensuring the long-term stability of the irradiation spacing and the centering position.

[0055] Furthermore, the uniform irradiation assembly 10 includes a gear cavity 101, which is located inside one end side plate of the sealed control cabinet 1. A spur gear ring 102 and a spur gear 103 are disposed within the gear cavity 101, meshing with each other. The spur gear ring 102 is concentrically and fixedly connected to one of the inner ring plates 5, and the rotation axis of the spur gear ring 102 is completely coincident with the rotation axis of the inner ring plate 5. A drive motor 104 is fixedly mounted on the outside of the sealed control cabinet 1 via a motor mount. The drive motor 104 is a variable frequency speed control motor, which can precisely adjust the rotation speed. The output end of the drive motor 104 is fixedly connected to the spur gear 103 through a coupling. When the drive motor 104 starts, it drives the spur gear 103 to rotate. Through the meshing transmission between the spur gear 103 and the spur gear ring 102, it drives the inner ring plate 5 to rotate. Then, through the connecting rod 6, it drives the adjusting round frame 91, the irradiation lamp 7, and the centering roller 8 to rotate circumferentially around the cable as the axis, so as to achieve continuous and uniform irradiation of 360 degrees.

[0056] Example 2, please refer to Figure 7 As shown:

[0057] The inlet and outlet ends of the sealed control cabinet 1 are equipped with sealing dustproof components 11 to prevent external dust and moisture from entering the equipment cavity and stabilize the irradiation processing environment. The sealing dustproof component 11 includes an internal thread 111 and a threaded disc 112. The internal thread 111 is formed on the inner wall of the cable through-hole at the inlet and outlet ends of the sealed control cabinet 1. The outer edge of the threaded disc 112 has an external thread that matches the internal thread 111. The internal thread 111 and the threaded disc 112 are detachably threaded. A sealing sponge 113 is bonded and fixed to the inner side of the threaded disc 112. The sealing sponge 113 is made of high-temperature resistant and UV-resistant polyurethane sponge, with a through-hole in the center for the cable to pass through. A concentrically fixed mounting device is also present on the outer side of the threaded disc 112. Equipped with a toothed disassembly ring 114, it is easy for operators to quickly disassemble and assemble the cable by rotating the threaded disc 112 with tools. After the cable is threaded, the threaded disc 112 is screwed into the internal thread 111. The edge of the central through hole of the sealing sponge 113 is squeezed to fit the outer surface of the cable, forming a flexible sealing barrier. This does not affect the axial movement of the cable, and can effectively prevent external dust, impurities and moisture from entering the inner cavity of the sealed control cabinet 1, avoiding interference from the external environment to the irradiation process. At the same time, sealing sponges 113 with different inner diameters can be customized according to the size of the cable.

[0058] Example 3, please refer to Figure 8 As shown:

[0059] The sealed control cabinet 1 is also equipped with a dust removal component 12, which is used to continuously purify the environment inside the sealed control cabinet 1 and remove suspended dust generated during processing. The dust removal component 12 includes a fixing rod 121. A circulating air nozzle 122 is fixedly connected to one side of the inner cavity of the sealed control cabinet 1 through multiple sets of fixing rods 121. The circulating air nozzle 122 is an annular nozzle, and multiple air holes 123 are evenly opened on the inner side of the circulating air nozzle 122. A circulating pump 124 is fixedly installed on the outer side of the sealed control cabinet 1 through a bracket. The input end of the circulating pump 124 is connected to the interface of the circulating air nozzle 122 through a first hose 125. The output end of the circulating pump 124 is detachably connected to a collection box 126 through a quick-release connector. The end of the collection box 126 away from the circulating pump 124 is connected to the other side of the inner cavity of the sealed control cabinet 1 through a second hose 127. The inner drawer is equipped with a dust filter 128, which uses a HEPA high-efficiency dust filter to effectively filter suspended dust in the gas inside the cavity. When the circulation pump 124 starts, it draws dust-laden gas from the cavity of the sealed control cabinet 1 through the air hole 123 on the inner side of the circulation nozzle 122 and delivers it to the collection box 126 through the first hose 125. When the dust-laden gas passes through the dust filter 128, the dust is intercepted and filtered. The clean gas flows back to the cavity of the sealed control cabinet 1 through the second hose 127, forming a closed-loop circulating airflow purification. During the processing, the cleanliness of the cavity is continuously maintained, preventing dust from adhering to the surface of the irradiation lamp 7 and affecting the luminous efficiency, or adhering to the surface of the cable and affecting the irradiation crosslinking effect.

[0060] Furthermore, the circulating air nozzle 122 is concentrically arranged with the inner ring plate 5, and the irradiation lamp 7 and the centering roller 8 are both located inside the circulating air nozzle 122, ensuring that the circulating air nozzle 122 will not interfere with the rotation of the irradiation lamp 7 and the centering roller 8. At the same time, the annular circulating air nozzle 122 can realize the extraction of airflow in the entire range of the inner cavity, improving the comprehensiveness and efficiency of dust removal and purification.

[0061] A cable processing method includes the following steps:

[0062] Step 1: Pre-processing before processing. Adjust the radial positions of the irradiation lamp 7 and the centering roller 8 according to the outer diameter specifications of the cable to be processed. The operator rotates the operating knob 935, causing the worm gear 934 to rotate. Through the meshing transmission between the worm gear 934 and the incomplete worm wheel plate 932, the incomplete worm wheel plate 932 slides along the slide groove 931, thereby driving the adjusting disc 92 to rotate within the adjusting frame 91. When the adjusting disc 92 rotates, the inner wall of the first transmission groove 911 pushes the sliding column at the end of the first transmission rod 95, causing the first transmission rod 95 to slide radially along the first frame plate 94, simultaneously adjusting multiple sets of irradiation lamps. The radial position of the irradiation lamp 7 is adjusted, and at the same time, the inner wall of the second transmission groove 912 pushes the sliding column at the end of the second transmission rod 98, causing the second transmission rod 98 to slide radially along the second frame plate 97, and the radial position of multiple sets of centering rollers 8 is adjusted simultaneously. The adjustment distance is observed through the scale groove on the guide plate, so that the inner diameter of the multiple sets of centering rollers 8 is matched with the outer diameter of the cable to be processed, and the distance between the irradiation lamp 7 and the cable surface reaches the preset optimal irradiation distance. After the adjustment is completed, the position of the adjustment plate 92 is automatically locked by the self-locking characteristics of the worm gear 934 and the incomplete worm wheel plate 932, without the need for additional locking operation.

[0063] Step 2: Cable threading and centering. The cable to be processed is threaded through the sealed dustproof assembly 11 at one end of the sealed control cabinet 1, and then through the inner ring plate 5 and the inner side of the circulating air nozzle 122, arranged concentrically. It then exits through the sealed dustproof assembly 11 at the other end of the sealed control cabinet 1, connecting the end of the cable to the external winding device. After threading, multiple sets of centering rollers 8 evenly distributed around the circumference are attached to the outer surface of the cable, limiting the cable from multiple directions and keeping it stably in the center position concentric with the inner ring plate 5. This completes the centering and positioning of the cable and prevents radial displacement during subsequent traction.

[0064] Step 3: Setting irradiation processing parameters. Start the irradiation lamp 7 for preheating. Set the power and wavelength parameters of ultraviolet irradiation according to the material characteristics and thickness of the insulation layer of the cable to be processed. At the same time, start the drive motor 104. The drive motor 104 drives the spur gear 103 to rotate. Through the meshing transmission of the spur gear ring 102, it drives the inner ring plate 5 to rotate. Then, through the connecting rod 6, it drives the circumferentially distributed irradiation lamps 7 and the centering roller 8 to rotate synchronously around the cable as the axis. By adjusting the speed of the drive motor 104 through frequency conversion, the rotation speed of the inner ring plate 5 is matched with the traction and winding speed of the cable to ensure that each section of the cable receives a uniform irradiation dose along the axial direction.

[0065] Step 4: Sealing and dust prevention and internal cavity purification. After the cable is threaded, align the threaded disc 112 containing the sealing sponge 113 with the internal thread 111 at the inlet and outlet of the sealed control cabinet 1. Rotate the threaded disc 112 through the toothed disassembly ring 114 to tighten and fix the threaded disc 112 with the internal thread 111. At this time, the edge of the central through hole of the sealing sponge 113 is attached to the outer surface of the cable to form a flexible seal barrier to prevent external dust and moisture from entering. At the same time, start the circulation pump 124. The circulation pump 124 draws dust-laden gas from the inner cavity of the sealed control cabinet 1 through the air hole 123 on the inner side of the circulation nozzle 122 and delivers it to the collection box 126 through the first hose 125. When the dust-laden gas passes through the dust filter 128, the suspended dust is intercepted and filtered. The clean gas flows back to the inner cavity of the sealed control cabinet 1 through the second hose 127 to form a closed-loop circulating airflow purification, which continuously maintains the cleanliness of the inner cavity during the processing.

[0066] Step 5: Continuous irradiation processing. The external winding device is activated, driving the cable through the irradiation processing area inside the sealed control cabinet 1 at a preset uniform speed. Multiple sets of irradiation lamps 7 rotate synchronously in the circumference to continuously and uniformly irradiate the outer surface of the cable with 360° no dead angle. The ultraviolet light excites the photoinitiator inside the cable insulation layer to generate free radicals, which promotes the linear polymer chains to form a three-dimensional network cross-linked structure, completing the irradiation cross-linking processing of the cable insulation layer. During the processing, multiple sets of centering rollers 8 rotate synchronously with the inner ring plate 5, concentrically limiting the cable throughout the process to ensure that the cable is always in the irradiation center position. At the same time, the sealing dustproof component 11 and the dust removal component 12 continue to operate to maintain the stability of the irradiation environment.

[0067] Step Six: After processing is completed, turn off the external winding device, drive motor 104, irradiation lamp 7 and circulation pump 124 in sequence. After the irradiation lamp 7 cools down, unscrew the threaded discs 112 at both ends and take the processed cable out of the equipment to complete the irradiation processing of the entire cable. After long-term use, the inspection door on the top of the sealed control cabinet 1 can be opened to replace the irradiation lamp 7. At the same time, the collection box 126 can be removed to clean or replace the internal dust filter 128 to ensure the long-term stable operation of the equipment.
