Description

Technical Field

[0001] This invention belongs to the technical field of cable processing equipment, specifically a heat treatment device for bonding the insulation layer of a single-core cable. Background Technology

[0002] After the insulation layer is processed and applied to single-core cables, problems such as poor adhesion between the core and the insulation layer and insufficient interfacial bonding force often occur, making it difficult to achieve the ideal bonding effect. This can easily lead to defects such as insulation layer delamination, slippage, and separation, directly affecting the electrical insulation performance, mechanical stability, and long-term service life of the cable. To ensure that the core and the insulation layer form a firm and uniform bonded structure, the industry typically adopts a composite process of heat treatment combined with extrusion: the insulation layer is heated by precise temperature control, which softens the insulation material and increases its fluidity, improving its ability to wet and adhere to the surface of the core; at the same time, appropriate mechanical extrusion force is applied, allowing the softened insulation layer to tightly adhere to the surface of the core, eliminating interfacial gaps, strengthening the wrapping density and interfacial bonding strength, thereby significantly improving the bonding effect between the core and the insulation layer, ensuring the overall structural stability and safe use of the cable.

[0003] For example, the invention disclosed in CN111508664B discloses a heat treatment device for bonding the insulation layer in single-core cable processing. This device aims to solve the problem that after the cable is extruded from an extruder, rapid cooling is required, causing the outer insulation layer to shrink rapidly upon cooling, leading to increased cable stress and partial detachment of the core material from the outer insulation layer, thus affecting the use of the single-core cable. The device includes a chassis with heat insulation plates I and II horizontally installed inside. These heat insulation plates I and II divide the chassis cavity from top to bottom into a take-up chamber, a heat treatment chamber, and a pay-off chamber. Multiple heating plates are mounted on the inner wall of the heat treatment chamber via supports. A take-up reel is rotatably installed in the take-up chamber, along with a meter counter for single-core cable metering. A pay-off reel is rotatably installed in the pay-off chamber. A cable transfer roller is rotatably installed on the inner wall of the heat treatment chamber. This device is particularly suitable for heat treatment processing of single-core cables and has high social value and application prospects.

[0004] In existing technologies, pressing heated cables with horizontal and vertical pressure bonding rollers can effectively increase the tightness and adhesion of the insulation layer. However, the existing clamping structure cannot be adjusted, and the diameter of the cables being processed also varies, making it impossible for the existing device to flexibly adapt to different cable processing needs. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides an insulation layer adhesive heat treatment device for processing single-core cables, which solves the problem that existing clamping structures cannot be adjusted and the diameters of the cables being processed also vary, making it impossible for existing devices to flexibly adapt to different cable processing needs.

The linkage switching component includes three sets of limiting guide rails. A guide rail is slidably arranged on one side of the limiting guide rail, and a guide groove is opened on the inner side of the guide rail. Several sets of sliding columns are slidably arranged on the inner side of the guide groove. A limiting plate is installed between two sets of sliding columns, and a limiting bracket is installed on the side of the limiting plate away from the limiting guide rail. A pressing wheel is rotatably arranged on the inner side of the limiting bracket.

[0007] Preferably, an adjustment shaft is installed on the top of the large gear plate, and an adjustment motor is fixedly installed at the input end of the adjustment shaft. A fixing bracket is installed at the bottom of the adjustment motor by bolts, and the fixing bracket is welded to the top of the main housing. A bidirectional lead screw is installed at the bottom of the large gear plate.

[0008] Preferably, a set of fixing cylinders is installed on the outer side of the three sets of limiting guide rails, and the fixing cylinders are welded to the inner wall of the main box through a bracket. Two sets of guide rail grooves are opened on one side of the limiting guide rails, and several sets of limiting rods are installed on one side of the limiting guide rails. The limiting plate is slidably arranged on the outer side of the limiting rods.

[0009] Preferably, guide rail posts are installed on the upper and lower ends of the guide rail near the limiting guide rail, and the guide rail posts are slidably disposed on the inner side of the guide rail groove.

[0010] Preferably, two sets of connecting arc plates are welded between the two sets of guide rails, and a connecting column is installed between the two sets of connecting arc plates. The bottom of the connecting column is connected to the top of the connecting arc plate by a rod.

[0011] Preferably, a linkage adjustment component is movably provided on the outer side of the bidirectional lead screw; The linkage adjustment component includes two sets of lead screw sliders. The lead screw sliders are slidably arranged on the outside of the bidirectional lead screw. A limit ring is installed at the end of the lead screw slider away from the bidirectional lead screw, and five sets of drive plates are flipped on the outside of the limit ring.

[0012] Preferably, a set of arc-shaped heating plates is rotatably connected to one end of the two sets of driving plates away from the limiting ring, and several sets of positioning plates are provided on the outer side of the limiting ring and the arc-shaped heating plates, with the driving plates rotatably positioned on the inner side of the positioning plates.

[0013] Preferably, the linkage adjustment component includes a heat insulation cylinder, which is welded to the inner wall of the main housing via a bracket. Five sets of limiting frames are installed on the inner side of the heat insulation cylinder, and limiting posts are slidably arranged on the inner side of the limiting frames. The limiting posts are fixedly installed on the side of the arc-shaped heating plate near the heat insulation cylinder.

[0014] Preferably, a winding box is provided on both sides of the upper end of the main box, a gear drive module is provided on the top of the main box, two sets of auxiliary guide wheels are provided on both sides of the lower end of the main box, and a water cooling component is provided on one side of the upper end of the main box, the water cooling component being fixedly located above the movable ring.

[0015] Preferably, the output end of the gear drive module is equipped with a rotating shaft, and a cable transmission roller is provided on the outer side of the rotating shaft. The cable transmission roller is rotatably arranged between the five sets of arc-shaped heating plates, and an argon gas filling assembly is provided at the bottom of the inner side of the main housing.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordination of a linkage switching component and an adjusting shaft, facilitates the adjustment of extrusion rollers of different sizes, thereby adapting to the needs of cables with different diameters. When the adjusting shaft rotates, it drives a large gear plate to rotate, which in turn meshes with a small gear plate, causing the adjusting screw to rotate. Under the action of the thread, the adjusting slider slides up and down. During adjustment, the side movable ring, in conjunction with the rod, drives the three sets of connecting arc plates to slide up and down. During adjustment, the guide rail column slides along the inner side of the guide rail groove. During adjustment, the guide groove of the guide rail guides the sliding column to slide laterally along the limit rod. Through the predetermined guide groove, four sets of extrusion rollers can be adjusted to a fully extended state. Combined with the other two sets of extrusion rollers, a completely circular structure is formed in the center, with the diameter of the central circle gradually decreasing, thus extruding the cable on the inner side. The linkage switching component allows for flexible adjustment of the corresponding extrusion rollers to move closer to the center according to different cable diameters, thereby adapting to different needs.

[0017] This invention, through the coordinated arrangement of a linkage adjustment component and an adjustment shaft, facilitates the synchronous adjustment of the spacing of the arc-shaped heating plates, thereby adapting to cable insulation layers of varying thicknesses. During the rotation of the adjustment shaft, a bidirectional lead screw rotates synchronously, causing the upper and lower sets of lead screw sliders to move towards the center and outwards. During this outward movement, the lead screw sliders drive a limiting ring to one end synchronously. Combined with the drive plate, this allows the arc-shaped heating plates and limiting posts to slide laterally along the limiting frame. This lateral sliding adjustment changes the spacing with the cable transmission roller, and by controlling the spacing, the heating effect is altered to accommodate cables of different diameters. Furthermore, it enables heating treatment of insulation layers of varying thicknesses to ensure optimal heating performance. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 6 As shown, the present invention provides a heat treatment device for the adhesive bonding of the insulation layer in the processing of single-core cables, including a main housing 100, and a linkage switching component 001 is provided on one side of the upper end of the main housing 100. The linkage switching component 001 includes a large gear disk 204, a small gear disk 206 meshing with one side of the large gear disk 204, and an adjusting screw 200 installed at the bottom of the small gear disk 206. An adjusting slider 406 is slidably arranged on the outer side of the adjusting screw 200, and a movable ring 405 is installed on one side of the adjusting slider 406. The linkage switching component 001 includes three sets of limiting guide rails 301. A guide rail 400 is slidably arranged on one side of the limiting guide rail 301, and a guide groove 402 is opened on the inner side of the guide rail 400. Several sets of sliding columns 304 are slidably arranged on the inner side of the guide groove 402. A limiting plate 305 is installed between two sets of sliding columns 304, and a limiting bracket 306 is installed on the side of the limiting plate 305 away from the limiting guide rail 301. A pressing wheel 300 is rotatably arranged on the inner side of the limiting bracket 306.

[0022] The above scheme employs the following: the main housing 100 is the main structure of the device, and its interior is enclosed. The large gear disc 204 engages with and drives the small gear disc 206 to rotate and adjust its speed. When the adjusting screw 200 rotates synchronously, it drives the adjusting slider 406 to slide up and down. The limiting guide rail 301 restricts the internal structure, limiting its up and down sliding adjustment. The guide rail 400 guides and adjusts the sliding column 304 through its internal curved structure. The guide groove 402 restricts the sliding column 304. When the sliding column 304 slides and adjusts inside the guide groove 402, it slides laterally along the limiting rod 303. The limiting plate 305 maintains the stability of the sliding adjustment. The limiting bracket 306 further restricts the inner pressing roller 300. The combination of the three sets of pressing rollers 300 forms a circular space, which can tightly adhere to the insulation layer of the cable, thereby achieving the effect of applying pressure and maintaining a tight bond with the wire core.

[0023] like Figure 2 - Figure 5 As shown, an adjustment shaft 203 is installed on the top of the large gear 204, and an adjustment motor 202 is fixedly installed at the input end of the adjustment shaft 203. A fixed bracket 201 is installed at the bottom of the adjustment motor 202 by bolts, and the fixed bracket 201 is welded to the top of the main housing 100. A two-way lead screw 205 is installed at the bottom of the large gear 204.

[0024] A set of fixing cylinders 307 are installed on the outer side of the three sets of limiting guide rails 301, and the fixing cylinders 307 are welded to the inner wall of the main housing 100 through the bracket. Two sets of guide rail grooves 302 are opened on one side of the limiting guide rails 301, and several sets of limiting rods 303 are installed on one side of the limiting guide rails 301. The limiting plate 305 is slidably arranged on the outer side of the limiting rods 303.

[0025] Guide rail posts 401 are installed on the upper and lower ends of the guide rail 400 near the limiting guide rail 301. The guide rail posts 401 are slidably arranged inside the guide rail groove 302.

[0026] Two sets of connecting arc plates 403 are welded between the two sets of guide rails 400, and a connecting column 404 is installed between the two sets of connecting arc plates 403. The bottom of the connecting column 404 is connected to the top of the connecting arc plate 403 through a rod.

[0027] Using the above scheme: After the fixed bracket 201 is welded, it can provide support for the top adjustment motor 202. After the adjustment motor 202 is powered on, it can drive the bottom bidirectional lead screw 205 and the large gear plate 204 to rotate through the adjustment shaft 203. The two ends of the bidirectional lead screw 205 have opposite threads. When rotating, it can drive the outer lead screw slider 600 to move closer or outward through the threads. The fixed cylinder 307 can restrict the inner limit guide rail 301, effectively ensuring the stability of the inner structure. The guide rail groove 302 can guide the guide rail column 401. The limit rod 303 can restrict the limit plate 305, effectively ensuring the guiding and adjustment effect. The connecting arc plate 403 can connect the guide rails 400. When the movable ring 405 moves up and down, it will synchronously control the guide rails 400 to adjust and change the spacing of the extrusion rollers 300.

[0028] like Figure 5 As shown, a linkage adjustment component 002 is movably installed on the outer side of the bidirectional lead screw 205; The linkage adjustment component 002 includes two sets of lead screw sliders 600. The lead screw sliders 600 are slidably disposed on the outside of the bidirectional lead screw 205. A limit ring 607 is installed on the end of the lead screw slider 600 away from the bidirectional lead screw 205, and five sets of drive plates 606 are flipped on the outside of the limit ring 607.

[0029] Two sets of drive plates 606 are rotatably connected to an arc-shaped heating plate 604 at the end away from the limiting ring 607. Several sets of positioning plates 605 are provided on the outer side of the limiting ring 607 and the arc-shaped heating plate 604, and the drive plates 606 are rotatably positioned on the inner side of the positioning plates 605.

[0030] The linkage adjustment component 002 includes a heat insulation cylinder 601, which is welded to the inner wall of the main housing 100 via a bracket. Five sets of limiting frames 602 are installed on the inner side of the heat insulation cylinder 601, and limiting posts 603 are slidably arranged on the inner side of the limiting frames 602. The limiting posts 603 are fixedly installed on the side of the arc-shaped heating plate 604 near the heat insulation cylinder 601.

[0031] The main housing 100 has winding boxes 101 on both sides of the upper end, a gear drive module 102 on the top of the main housing 100, two sets of auxiliary guide wheels 103 on both sides of the lower end of the main housing 100, and a water cooling component 104 on one side of the upper end of the main housing 100. The water cooling component 104 is fixed above the movable ring 405.

[0032] A rotating shaft 105 is installed at the output end of the gear drive module 102, and a cable transmission roller 106 is provided on the outer side of the rotating shaft 105. The cable transmission roller 106 is rotatably arranged between five sets of arc-shaped heating plates 604, and an argon filling assembly 107 is provided at the bottom of the inner side of the main housing 100.

[0033] Using the above scheme: the spacing of the lead screw slider 600 can be adjusted by the rotation of the bidirectional lead screw 205. The limiting ring 607 can assist in pushing the drive plate 606 for adjustment by adjusting the lead screw slider 600. When the drive plate 606 is adjusted, it will cooperate with the positioning plate 605 to push each group of arc heating plates 604 to adjust the spacing. By adjusting the spacing, the distance with the cable is changed to achieve the heating effect and adapt to different cable thicknesses. The heat insulation cylinder 601 can isolate the internal heat and reduce the impact on the external environment. The limiting frame 602 can limit the limiting post 603 to ensure... The stability of the limit post 603 is adjusted by sliding. The winding box 101 is the winding mechanism. The kinetic energy transmission of the gear drive module 102 can drive the winch structure to rotate, thereby releasing and winding the cable to assist in cable transmission and processing. The auxiliary guide wheel 103 can adjust and turn the cable. The water cooling component 104 can quickly cool the cable through water cooling. The rotating shaft 105 can drive the cable transmission roller 106 to rotate, which can assist in cable transmission. The argon filling component 107 can fill argon to protect the cable during processing and prevent cable oxidation.

[0034] The working principle and usage process of this invention: When the adjusting shaft 203 rotates, it will drive the large gear disk 204 to rotate. The large gear disk 204 meshes with the small gear disk 206 to drive the adjusting screw 200 to rotate. Under the action of the screw, the adjusting slider 406 will be pushed to slide up and down for adjustment. During the adjustment process, the side movable ring 405 cooperates with the rod to drive the three sets of connecting arc plates 403 to slide up and down for adjustment. During the adjustment process, the guide column 401 will slide along the inner side of the guide groove 302. During the adjustment, the guide groove 402 of the guide rail 400 will guide the sliding column 304 to slide laterally along the limiting rod 303. Through the predetermined guide groove 402, four sets of extrusion wheels 300 can be adjusted to be in a fully unfolded state. After being combined with the other two sets of extrusion wheels 300, the middle part will be completely circular, and the diameter of the middle circle will gradually decrease, thereby extruding the inner cable. During the rotation of the adjusting shaft 203, the bidirectional lead screw 205 will rotate synchronously. During the rotation, the upper and lower sets of lead screw sliders 600 will move towards the center and outward. During the outward movement, the lead screw slider 600 will drive the limiting ring 607 to one end synchronously. In conjunction with the drive plate 606, the arc-shaped heating plate 604 and the limiting post 603 can be laterally slid along the limiting frame 602. By adjusting the lateral sliding, the distance between the heating plate and the cable transmission roller 106 can be changed. By controlling the distance, the heating effect can be changed to adapt to cables of different diameters.
