Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically, to a cable insulation layer grinding device. Background Technology

[0002] Cable insulation is a layer that wraps around the cable conductor, providing electrical insulation. It prevents current leakage, ensures the safe operation of the cable, and avoids safety accidents caused by current leakage. Cable insulation materials typically possess good insulation properties, heat resistance, corrosion resistance, and mechanical strength. Common insulation materials include polyvinyl chloride (PVC), polyethylene (PE), and cross-linked polyethylene (XLPE). Different insulation materials are suitable for different cable applications. For example, PVC insulation has good flexibility and chemical corrosion resistance and is commonly used in general low-voltage cables; XLPE insulation has higher heat resistance and electrical properties and is suitable for medium- and high-voltage cables. The quality and performance of the insulation layer are crucial during cable production and use, requiring strict control and testing. The process of polishing the cable insulation layer is also important for ensuring the connection quality and performance of the cable. For example, it can remove impurities and oxide layers from the insulation surface, improving the reliability of the connection between the cable and other components.

[0003] According to patent document CN119217224A, a cable joint insulation layer grinding device, belonging to the field of cable construction, is disclosed. It includes two supports, each with a first guide rod connected to both ends. One support has a first fixing device, and the other has a second fixing device. A rotating base is mounted on the first guide rod. The rotating base includes an inner cylinder with symmetrically connected support arms on both sides. The lower ends of the support arms are mounted on the first guide rod. An outer cylinder is rotatably connected to the inner cylinder via bearings. A first fixing plate is fixedly mounted on one side of the outer cylinder, and the grinding assembly is mounted on the first fixing plate. This invention utilizes the first and second fixing devices to clamp and pull the cable until it is taut, avoiding the impact of cable end swaying on the grinding effect and preventing injuries caused by cable end swaying. Simultaneously, this taut state facilitates the grinding operation and improves grinding efficiency.

[0004] In cable insulation polishing, manual operation makes it difficult to ensure uniform polishing force and speed, easily leading to uneven insulation thickness. This affects the cable's insulation performance and subsequent safety. When using fully automated equipment, bending or unevenness of the cable surface during winding can cause uneven contact between the polishing equipment and the cable surface, resulting in over- or under-polishing. Furthermore, both manual and fully automated polishing methods generate a large amount of dust and debris. If not cleaned promptly and effectively, this not only deteriorates the working environment but may also endanger the health of operators, increase the risk of insulation surface contamination, and further adversely affect cable performance. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a cable insulation layer grinding device. The technical problem this invention aims to solve is that when manually holding the grinding tool, it is difficult to ensure the uniformity of grinding force and speed, which easily leads to uneven grinding thickness of the insulation layer, thereby affecting the insulation performance and subsequent safety of the cable. When using fully automatic equipment for grinding, some cables may bend or have uneven surfaces during the winding process, resulting in uneven contact between the grinding equipment and the cable surface, which may lead to over-grinding or under-grinding. In addition, both manual and fully automatic grinding methods may generate a large amount of dust and debris. If not cleaned in a timely and effective manner, it will not only deteriorate the working environment but may also endanger the health of operators, while increasing the risk of contamination of the insulation layer surface, further adversely affecting the cable performance.

A columnar tube 21115 is movably connected to the middle of the inner wall of the connecting plate 2111. A U-shaped vertical connecting block 21117 is provided at the front end of the columnar tube 21115. A bidirectional electric push rod 21119 is fixedly connected to the bottom of the inner wall of the U-shaped vertical connecting block 21117.

Rotating side arms 21122 are rotatably connected to both sides of the inner wall of the U-shaped vertical connecting block 21117. Rotating side arm push blocks 21121 are fixedly connected to both ends of the bidirectional electric push rod 21119. The outer walls of the two rotating side arm push blocks 21121 are rotatably connected to the bottom of the inner walls of the two rotating side arms 21122. Clamping side plates 21123 are fixedly connected to the top of the inner sides of the two rotating side arms 21122. Rotary wheels 21124 are rotatably connected to the inner sides of the two clamping side plates 21123. The grinding disc 212 includes a guide disc 2121. Guide grooves 2122 are provided on three sides of the guide disc 2121. A push-pull tube 2123 is slidably connected to the inner wall of the guide disc 2121.A hinge sleeve 2124 is fixedly connected to the front end of the push-pull tube 2123. An electric push rod connecting block 2125 is fixedly connected to the bottom of the front middle part of the guide plate 2121. An electric push rod 2126 is fixedly connected to the inner wall of the electric push rod connecting block 2125. The front end of the electric push rod 2126 is fixedly connected to the rear bottom of the push-pull block 21118. Connecting rods 2127 are fixedly connected to three sides of the outer wall of the guide plate 2121. The front sides of the three connecting rods 2127 are fixedly connected to the rear sides of the C-shaped toothed plate 21114. The inner walls of the three guide grooves 2122 opened in the guide plate 2121 are slidably connected to expansion and contraction plates 2. 128. A grinding component connecting block 21210 is fixedly connected to the rear side of each of the three expanding plates 2128. A expanding plate rotating rod 2129 is rotatably connected to the front side of the inner side of each of the three expanding plates 2128. The side of each of the three expanding plate rotating rods 2129 away from the expanding plates 2128 is rotatably connected to three sides of the outer wall of the hinge sleeve 2124. A grinding component L-shaped connecting rod 21211 is fixedly connected to the front side of each of the three grinding component connecting blocks 21210. A grinding component 21212 is fixedly connected to the inner side of each of the three grinding component L-shaped connecting rods 21211. The front end of the hinge sleeve 2124 is fixedly connected to the rear end of the columnar tube 21115. When it is necessary to polish the cable insulation layer, the cable is wound towards the cable winding roller 13 by the cable conveying roller 12. During this process, the cable passes through the columnar tube 21115 and the push-pull tube 2123. When the part to be polished is inside the multiple polishing parts 21212, the bidirectional electric push rod 21119 is first activated to push the rotating side arm push blocks 21121 at both ends to rotate to both sides. Then, the two rotating side arms 21122 rotate to both sides under the push of the bidirectional electric push rod 21119. Then, the two rotating side arms 21122 will rotate inward around the rotating connection point with the U-shaped vertical connecting block 21117. As the rotating side arms 21122 rotate, the clamping side plates 21123 on their inner top will also move, causing the two clamping side plates 21123 to move closer to each other. Since the inner sides of the two clamping side plates 21123 are rotatably connected with rotating wheels 21124, the rotating wheels 21124 will gradually fit against the outer wall of the cable, clamping and positioning the cable from both sides, ensuring that the cable remains stable and does not shake during the grinding process. At this time, the electric push rod 2126 is activated, which pushes the push-pull block 21118 to move backward. The push-pull block 21118 drives the ring 21120 at its top and the columnar tube 21115 connected to the ring 21120 to move backward. Since the hinge sleeve 2124 is fixedly connected to the rear end of the columnar tube 21115, the hinge sleeve 2124 will also move backward along with the columnar tube 21115. At this time, since the cable part is fixed inside the two rotating wheels 21124, when the rotating wheels 21124 move backward, they pull one end of the cable to move backward, thereby ensuring the tension of the cable during grinding. When the hinge sleeve 2124 moves backward, it will drive the expansion plate rotating rod 2129, which is rotatably connected to the three sides of its outer wall, to move. The movement of the expansion plate rotating rod 2129 causes the expansion plate 2128 to slide in the guide groove 2122 opened in the guide plate 2121. As the expansion plate 2128 slides, the three expansion plates 2128 gradually approach each other, thereby driving the grinding part connecting block 21210, which is fixedly connected to the rear side of the expansion plate 2128, as well as the grinding part L-shaped connecting rod 21211 and the grinding part 21212 connected to the grinding part connecting block 21210, to approach the cable until the grinding part 21212 is attached to the outer wall of the cable insulation layer. Then, the motor 2119 is started. The output end of the motor 2119 drives the left columnar transmission rod 2114 to rotate. The left columnar transmission rod 2114 drives the gear 2115 at its rear end to rotate. Since the two gears 2115 are connected to the transmission disk 2116 through the track 2117, the right columnar transmission rod 2114 and the gear 2115 will also rotate. The rotation of the two gears 2115 will drive the C-shaped toothed disk 21114 that meshes with their outer walls to rotate on the outer wall of the C-shaped toothed disk guide disk 21116. When the C-shaped toothed disc 21114 rotates, it drives the guide disc 2121 to rotate through the connecting rod 2127. This causes the grinding part 21212, which is connected to the guide disc 2121, to move in a circular motion around the cable, grinding the cable insulation layer in all directions. If it is necessary to adjust the grinding force or range, the extension and retraction of the electric push rod 2126 can be adjusted to change the degree of contact between the grinding part 21212 and the cable. Alternatively, the extension and retraction of the bidirectional electric push rod 21119 can be controlled to adjust the clamping force of the rotating wheel 21124 on the cable, further ensuring the stability and grinding effect of the grinding process.

[0022] like Figure 10As shown, the grinding chamber 22 includes a grinding chamber shell 221. A debris storage bin 222 is fixedly connected to the top of the grinding chamber shell 221. Side uprights 223 are fixedly connected to both the left and right sides of the debris storage bin 222. The inner sides of the two side uprights 223 are fixedly connected to the rear sides of the outer sides of the two side connecting rods 21113. A debris extraction device 224 is fixedly connected to the bottom of the outer wall of the grinding chamber shell 221. Pipes 2 are fixedly connected to both the left and right sides of the rear side of the debris storage bin 222. 25. The ends of the two pipes 225 furthest from the debris storage bin 222 are fixedly connected to the left and right sides of the debris extraction component 224. A circular guide disc 226 is fixedly connected to the rear side of the grinding chamber shell 221. An external gear disc 227 is rotatably connected to the outer wall of the circular guide disc 226. An internal gear disc 228 is fixedly connected to the inner side of the external gear disc 227. A second gear 2214 is provided on one side of the outer wall of the external gear disc 227. The outer wall of the second gear 2214 is connected to the external gear disc 227. The outer wall meshes with the second gear 2214, and the rear side of the second gear 2214 is fixedly connected to the second gear transmission rod 2215. The front side of the outer wall of the second gear transmission rod 2215 is rotatably connected to the inner wall of the L-shaped connecting plate 2113. The front end of the second gear transmission rod 2215 is fixedly connected to the output end of the second motor 21110. The front side of the circular guide disk 226 is fixedly connected to the L-shaped guide block 229 in a ring array. The front side of the grinding chamber shell 221 is arranged in a ring array on one side of the inner side of the circular guide disk 226. Rotary transmission gears 2210 are rotatably connected. The outer walls of multiple transmission gears 2210 mesh with the inner walls of the inner gear disk 228 on multiple sides. The front sides of multiple L-shaped guide blocks 229 are slidably connected to rack rods 2211. One side of multiple rack rods 2211 meshes with the outer walls of multiple transmission gears 2210. The front sides of multiple rack rods 2211 are fixedly connected to fan-shaped expansion plates 2212. The inner sides of multiple fan-shaped expansion plates 2212 are rotatably connected to second rotating wheels 2213. During grinding, the grinding disc 212 rotates at high speed inside the grinding chamber shell 221. The strong friction generated will grind away the impurities and excess parts on the cable insulation layer. During the grinding process, the generated debris will be drawn into the debris storage bin 222 through the pipe 225 by the debris extraction component 224, so as to avoid the debris from accumulating in the grinding chamber 22 and affecting the grinding effect, and also to prevent the debris from flying into the surrounding environment and causing pollution. Before grinding, the second motor 21110 is started. The second motor 21110 drives the second gear transmission rod 2215 to rotate, which in turn drives the second gear 2214 to rotate. Since the second gear 2214 meshes with the outer gear disk 227, the outer gear disk 227 will rotate accordingly. The inner gear disk 228, which is fixedly connected to the inner side of the outer gear disk 227, will also rotate together. The inner gear disk 228 meshes with multiple transmission gears 2210. The rotation of the transmission gears 2210 will drive the rack rod 2211 meshing with it to slide on the L-shaped guide block 229. Since the front side of multiple rack rods 2211 is fixedly connected with fan-shaped expansion plates 2212, the fan-shaped expansion plates 2212 will expand and contract as the rack rods 2211 slide, thereby adjusting the multiple fan-shaped expansion plates 2212 to close the rear opening space of the grinding chamber shell 221, preventing debris from overflowing from the rear opening during the grinding process. In addition, during the grinding process, the closing of the second rotating wheel 2213 can play a role in supporting the cable, reducing the shaking of the cable during grinding, making the grinding more stable and precise. Moreover, the second rotating wheel 2213 inside the multiple fan-shaped expansion plates 2212 can rotate with the movement of the cable, ensuring that the cable can pass smoothly in the grinding chamber 22 and improving grinding efficiency.

[0023] Working principle of the invention: When it is necessary to polish the cable insulation layer, the cable is wound towards the cable winding roller 13 by the cable conveying roller 12. During this process, the cable passes through the columnar tube 21115 and the push-pull tube 2123. When the part to be polished is inside the multiple polishing parts 21212, the bidirectional electric push rod 21119 is first activated to push the rotating side arm push blocks 21121 at both ends to rotate to both sides. Then, after the bidirectional electric push rod 21119 pushes the rotating side arm push blocks 21121 at both ends to rotate to both sides, the two rotating side arms 21122 will, with their interaction with U... The rotating connection of the upright connecting block 21117 rotates inward. As the rotating side arm 21122 rotates, the clamping side plate 21123 on its inner top also moves, causing the two clamping side plates 21123 to move closer to each other. Since the inner sides of the two clamping side plates 21123 are rotatably connected to the rotating wheels 21124, the rotating wheels 21124 will gradually fit against the outer wall of the cable, clamping and positioning the cable from both sides to ensure that the cable remains stable and does not shake during the grinding process. At this time, the electric push rod 2126 is activated, and the electric push rod 2126 pushes the push-pull block 21118 backward. The push-pull block 21118 moves its top ring 21120 and the cylindrical tube 21115 connected to the ring 21120 backward. Since the hinge sleeve 2124 is fixedly connected to the rear end of the cylindrical tube 21115, the hinge sleeve 2124 also moves backward along with the cylindrical tube 21115. At this time, since the cable part is fixed inside the two rotating wheels 21124, when the rotating wheels 21124 move backward, they pull one end of the cable backward, thereby ensuring the tension of the cable during grinding. When the hinge sleeve 2124 moves backward, it will drive the three sides of its outer wall to rotate. The rotating rod 2129 of the expansion plate moves, causing the expansion plate 2128 to slide within the guide groove 2122 of the guide plate 2121. As the expansion plate 2128 slides, the three expansion plates 2128 gradually move closer to each other, thereby driving the grinding part connecting block 21210 fixedly connected to the rear side of the expansion plate 2128, as well as the grinding part L-shaped connecting rod 21211 and the grinding part 21212 connected to the grinding part connecting block 21210, to move closer to the cable until the grinding part 21212 is attached to the outer wall of the cable insulation layer. During grinding, the grinding disc 212... The entire assembly is located inside the grinding chamber housing 221. Before grinding, the second motor 21110 is started. The second motor 21110 drives the second gear transmission rod 2215 to rotate, which in turn drives the second gear 2214 to rotate. Since the second gear 2214 meshes with the outer gear disk 227, the outer gear disk 227 will rotate accordingly. The inner gear disk 228, which is fixedly connected to the inner side of the outer gear disk 227, will also rotate together. The inner gear disk 228 meshes with multiple transmission gears 2210. The rotation of the transmission gears 2210 will drive the rack rod 2211, which meshes with it, to slide on the L-shaped guide block 229.Because the front sides of multiple rack rods 2211 are fixedly connected to fan-shaped expansion and contraction plates 2212, the fan-shaped expansion and contraction plates 2212 will expand and contract as the rack rods 2211 slide, thereby adjusting the multiple fan-shaped expansion and contraction plates 2212 to close the rear opening space of the grinding chamber shell 221, preventing debris from overflowing from the rear opening during grinding. Then, the motor 2119 is started, and the output end of the motor 2119 drives the left columnar transmission rod 2114 to rotate. The left columnar transmission rod 2114 drives the gear 2115 at its rear end to rotate. Since the two gears 2115 are connected to the transmission disc 2116 through the track 2117, the right columnar transmission rod 2114 and the gear 2115 will also rotate accordingly. The rotation of 2115 causes the C-shaped gear disk 21114, which meshes with its outer wall, to rotate on the outer wall of the C-shaped gear disk guide disk 21116. When the C-shaped gear disk 21114 rotates, it drives the guide disk 2121 to rotate via the connecting rod 2127. This causes the grinding part 21212, connected to the guide disk 2121, to move in a circular motion around the cable, performing all-around grinding of the cable insulation layer. If it is necessary to adjust the grinding force or range, the extension or retraction of the electric push rod 2126 can be adjusted to change the degree of contact between the grinding part 21212 and the cable. Alternatively, the extension or retraction of the bidirectional electric push rod 21119 can be controlled to adjust the clamping force of the rotating wheel 21124 on the cable, further ensuring the stability and grinding effect of the grinding process.
