Description

Technical Field

[0001] The invention relates to the field of cable outer surface stripping processing, and in particular to an outer surface stripping device for cable processing. Background Art

[0002] Cable is made of one or more mutually insulated conductors and an outer insulating protective layer, used to transmit power or information from one place to another. It is usually a rope-like structure made of several or several groups of conductors (at least two in each group), each group of conductors is insulated from each other and often twisted around a center, and the entire outside is covered with a highly insulating covering.

[0003] With the advancement of technology and the continuous upgrading of equipment, the original cables may be eliminated and cannot be used normally because they cannot meet the performance requirements of new equipment, so they will be scrapped and recycled. In addition, during the use of cables, they may age or be damaged due to long-term exposure to harsh environments, excessive loads, or physical damage. These aged or damaged cables cannot continue to be used normally and will also be scrapped and recycled. In the process of scrapping and recycling cables, cable stripping equipment is required.

[0004] However, during the use of existing cable stripping equipment, the staff is required to manually support the cable until the protective layer on the outer surface of the cable is completely cut off. During this process, the protective layer of the cable is mixed with the separated copper wire and scattered on the ground. Therefore, the existing cable stripping equipment cannot separate and recycle the copper wire that needs to be recycled, so secondary separation and cleaning are required, so the labor intensity of the staff cannot be reduced. Moreover, after long-term use, the sharpness of the cable cutting knife decreases, which affects the cutting speed and efficiency of the cable. This requires the cutting knife to be replaced or polished, which affects the cutting and recycling of the cable. Therefore, the existing cable stripping equipment does not have a self-polishing function and cannot meet people's usage needs. Summary of the invention

A limiting slot 33 is opened in the middle of the support frame 36 and located on the periphery of the limiting hole 32.

[0046] The clamping component 4 includes an arc-shaped clamping plate 43 , the inner surface of which is evenly provided with clamping wheels 44 , the outer surface of which is centrally rotatably clamped with a third threaded rod 42 , and the outer surfaces of both ends of the arc-shaped clamping plate 43 are provided with limiting guide pillars 41 .

[0047] The two ends of the threaded conveying rod 15 of the present invention are rotatably connected with the end and the middle of the middle end of the support frame 36 respectively, which can ensure the stability of the rotation of the threaded conveying rod 15. The driving motor 19 is fixedly connected to the outer surface of the end of the supporting frame 36 to ensure the stability of the operation of the driving motor 19. A limiting cross bar is arranged at the lower part of the interior of the supporting frame 36, and sleeve holes adapted to the limiting cross bar are opened through the bottom of the two end surfaces of the pushing frame 11. Therefore, one end of the pushing frame 11 is slidably connected with the limiting guide rod through the first sleeve hole 14, which can limit the sliding of the pushing frame 11.

[0048] The transmission shaft 22 of the present invention is rotatably connected with the edges of the first threaded rod 38 on both sides of the top of the support frame 36, so as to limit the position of the transmission shaft 22 and ensure the stable rotation of the transmission shaft 22. The grinding frame 24 is slidably connected with the outer surface of the limiting rod 37 through the second sleeve hole 25, so as to limit the lifting and sliding of the grinding frame 24. The grinding frame 24 is in sliding contact with the outer surface of the double-edged cutting knife 314 through the grinding groove 211, so as to grind the blade of the double-edged cutting knife 314 and ensure the sharpness of the double-edged cutting knife 314. The two groups of ratchets 29 on both sides of the middle part of the support frame 36 are respectively adapted and meshed with the transmission tooth grooves 12 on the outer surfaces of the two ends of the pushing frame 11, so that when the pushing frame 11 slides, the grinding frame 24 can be driven to rise and fall. The two ends of the ratchet 29 are rotatably connected with the middle part of the support frame 36 through the limiting plug hole 32, so as to limit the rotation of the ratchet 29.

[0049] The second winding drum 210 of the present invention is rotatably connected with the side surface of the middle part of the support frame 36 through the limiting card slot 33, which can limit the rotation of the second winding drum 210. The arc clamping plate 43 is slidably connected with the two sides of the support frame 36 through the limiting guide column 41, which can limit the sliding of the arc clamping plate 43. The third threaded rod 42 is threadedly connected with the support frames 36 on both sides, and can adjust and control the distance between the two groups of arc clamping plates 43, so that cables of different sizes can be clamped and limited. The pawl 27 is movably connected with the ratchet 28 on the side of the second winding drum 210, which can limit the rotation of the ratchet 28, so that the second winding drum 210 can rotate unidirectionally on the outer surface of the ratchet 29. The outer surface of the lower feeding roller 316 is provided with a rubber layer, which can increase the friction between the lower feeding roller 316 and the copper wire, so that the copper wire can be transported to ensure that the copper wire falls into the storage box 31.

[0050] Moreover, when processing cables of different sizes, the second threaded rod 39 can be rotated to adjust the distance between the upper feeding rollers 315, thereby ensuring that the cable ends are stably transported, and the first threaded rod 38 can be rotated to adjust the distance between the two sets of double-edged cutting knives 314, so that cables of different layer thicknesses can be cut, avoiding the copper wire of the cutting knife affecting the cutting quality.

[0051] The working principle of the present invention is as follows: when recycling waste cables, first cut the longer cables at equal distances, then place the cut cable ends on the top of the roller 112 at one end of the pushing frame 11, then pull the positioning pin 110 to separate one end of it from the second extrusion head 16, so that the second extrusion head 16 deflects to the side, and then push the cable to align and plug in the center between the clamping component 4, and at the same time the clamping wheels 44 on both sides will contact the cable and limit the cable at the same time until the cable is completely plugged into the inside between the clamping components 4, then pull the positioning pin 110 to slide and squeeze the tensioning spring 111 to shrink, and then pull the second extrusion head 16 to reset and flip, and at the same time the end of the second extrusion head 16 will align and contact with the end of the cable, and at the same time remove the external force of the positioning pin 110, so that one end of the positioning pin 110 is plugged and positioned with the end face of the second extrusion head 16, and then start the drive motor 19 to drive the threaded conveying rod 1 through the transmission chain 18 5 rotates, thereby driving the pushing frame 11 to slide inside the supporting frame 36 as a whole. At the same time, the pushing frame 11 will push the cable end to move toward the middle of the supporting frame 36 through the second extrusion head 16 at the top of one end, so that the cable end enters between the upper feeding roller 315 and the double-edged cutting knife 314, and the upper and lower protective layers of the end surface of the cable contact the upper and lower double-edged cutting knives 314 in the middle of the supporting frame 36, so the double-edged cutting knife 314 will cut the protective layer on the outer surface of the moving cable up and down. As the cable moves, the cut protective layer of the cable end slides to both sides under the obstruction of the vertical guide plate 312, and the copper wire in the middle continues to move toward the other end of the supporting frame 36 through the arc groove 311 until the entire cable is stripped. At the same time, the protective layer outside the cable will fall on both sides of the middle of the supporting frame 36, and the internal copper wire will slide to the inside of the storage box 31 at the other end for collection;

[0052] When the cable is pushed to contact the lower feeding roller 316, the lower feeding roller 316 will be driven to rotate under the action of friction, and the lower feeding roller 316 will drive another group of lower feeding rollers 316 to rotate synchronously through the transmission gears 317 and the transmission toothed belt 318 at both ends. Therefore, after the copper wire passes through the arc groove 311 and penetrates the middle part of the vertical guide plate 312, the copper wire will overlap the upper surface of the lower feeding roller 316 at the other end, and the lower feeding roller 316 will continue to drive the copper wire to slide forward under the friction of the outer surface rubber layer until the copper wire falls into the inside of the storage box 31 for collection;

[0053] When the push rack 11 moves, it will drive a group of ratchets 29 away from the cable meshing connection to rotate through the transmission tooth groove 12 at one end, and at the same time, the ratchet 29 will drive the second winding disk 210 to wind up the connecting rope 26 through the ratchets 28 and the pawls 27 at both ends, so that the connecting rope 26 pulls the top grinding rack 24 to descend, and at the same time, the grinding groove 211 in the middle of the grinding rack 24 will descend along the blade of the double-edged cutting knife 314. When the grinding groove 211 descends to the bottom, the stripped copper wire will pass through the arc groove 311 and overlap the lower feeder The upper surface of the pressure roller 316, at this time, the grinding frame 24 is located below the copper wire, and the ratchet 29 will also be separated from the transmission tooth groove 12 on the upper surface of the pushing frame 11, so the transmission shaft 22 will drive the first winding discs 23 at both ends to wind up the connecting rope 26 under the elastic force of the torsion spring 21, thereby driving the grinding frame 24 to rise and contact the bottom of the copper wire, until the copper wire completely slides and falls into the storage box 31, the grinding frame 24 is not blocked and rises to reset, thereby performing a secondary grinding on the double-edged cutting knife 314 to ensure the sharpness of the double-edged cutting knife 314;

[0054] When the pushing frame 11 moves to the other end, the positioning pin 110 on the edge of the first extrusion head 13 can be pulled to slide and squeeze the tensioning spring 111 to contract, and then the first extrusion head 13 can be pulled to flip, and then the same operation can be performed to insert the cable between the clamping parts 4, and then the first extrusion head 13 is pulled to reset and flip, and at the same time, the end of the first extrusion head 13 will be aligned with the end of the cable, and at the same time, the external force of the positioning pin 110 is removed, so that one end of the positioning pin 110 is plugged and positioned with the end face of the second extrusion head 16, and then the driving motor 19 is continued to be controlled to rotate in the opposite direction, thereby driving the pushing frame 11 to reset and slide inside the supporting frame 36, and continue to push the cable for cutting. The cutting method also makes the protective layer fall to both sides, and the copper wire will enter the storage box 31 at the other end for collection, and it will also drive another set of grinding components 2 to grind the double-edged cutting knife 314 on the other side, thereby ensuring that the double-edged cutting knife 314 on both sides remains sharp;

[0055] The ratchet 28 at the end of the ratchet 29 is engaged with the pawl 27, so when the pushing frame 11 is reset and slid, it will not drive the second winding drum 210 to wind up the connecting rope 26, thereby ensuring that the cable is cut and processed normally. Therefore, through the coordinated operation of the extrusion component 1, the grinding component 2, the limiting component 3 and the clamping component 4, the cable can be automatically cut, and the protective layer and the copper wire of the cable can be separated and collected. In addition, during the cutting process, the double-edged cutting knife 314 can be grinded to ensure the sharpness of the double-edged cutting knife 314, and the cable can be efficiently cut, processed and recycled to meet people's usage needs.
