Description

Technical Field

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

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer, and is used to transmit electricity or information from one place to another. It is usually a rope-like structure twisted by several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a central wire, and the whole is wrapped with a highly insulating covering layer.

[0003] With the progress of technology and the continuous renewal of equipment, the original cables may be eliminated and unable to be used normally because they cannot meet the performance requirements of new equipment. Therefore, they will be scrapped and recycled. Moreover, 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. Among them, during the process of scrapping and recycling cables, cable stripping equipment is required.

[0004] However, during the use of existing cable stripping equipment, it is usually necessary for workers to manually hold the cable until the protective layer on the outer surface of the cable is completely cut open. During this process, the mixture of the protective layer of the cable and the separated copper wires will fall to the ground. Therefore, the existing cable stripping equipment cannot separate and recycle the copper wires to be recycled, so secondary separation and cleaning are required. Therefore, it cannot reduce the labor intensity of workers. Moreover, after the cable cutting knife is used for a long time, the sharpness of the cutting edge decreases, which will affect the cutting speed and efficiency of the cable. This requires replacing or grinding the cutting knife, which will affect the cutting and recycling of the cable. Therefore, the existing cable stripping equipment does not have a self-grinding function and cannot meet people's usage requirements. Summary of the Invention

[0021] The beneficial effects of the present invention:

[0022] (1) By arranging a vertical guide plate in the middle of the support frame, the present invention can limit and guide the cable protective layer that slides and cuts at both ends, so that the protective layer slides to both sides of the middle of the support frame, while the copper wire passes through the middle of the vertical guide plate through the arc-shaped groove and slides to one end and enters the inside of the storage box for collection.

At the same time, by alternately feeding the cable at both ends of the support frame, the time for the staff to prepare the cable can be shortened, thereby improving the efficiency of the wire stripping process on the outer surface of the cable;

[0024] (3) Through the coordinated operation of the extrusion component, the polishing component, the limiting component and the clamping component, the present invention can automatically cut the cable, and at the same time can separate and collect the protective layer and the copper wire of the cable.

[0043] The limiting component 3 includes a support frame 36, an electric control box 35 is fixedly installed on one side of one end of the support frame 36, storage boxes 31 are installed at the bottoms of both ends of the support frame 36, a connecting frame 310 is slidably inserted into the center of the top of the support frame 36, a second threaded rod 39 which is rotationally clamped with the top of the connecting frame 310 is threadedly connected to the center of the top of the support frame 36, and first threaded rods 38 are symmetrically threadedly connected to the center of the support frame 36 and below the second threaded rod 39;

[0044] One end of the first threaded rod 38 is rotatably clamped with a double-edge cutting knife 314. Limiting rods 37 are symmetrically arranged on both sides of the middle part of the support frame 36. Transverse guide plates 34 are fixedly installed on both sides of the middle part of the support frame 36. Lower feeding pressure rollers 316 are symmetrically and rotatably clamped on the upper surface of the middle part of the support frame 36.

[0045] Drive gears 317 are fixedly installed on the outer surfaces of both ends of the lower feeding pressure roller 316.

The two lower feeding pressure rollers 316 on the upper surface of the middle part of the support frame 36 are rotationally connected through the drive toothed belt 318. A limiting guide rod is arranged in the middle of the outer surface of the support frame 36 away from the electric control box 35. Limiting insertion holes 32 are symmetrically opened below both sides of the middle part of the support frame 36. Limiting clamping grooves 33 are opened around the limiting insertion holes 32 in the middle of the support frame 36.

[0046] The clamping component 4 includes an arc-shaped clamping plate 43. Clamping wheels 44 are uniformly arranged on the inner surface of the arc-shaped clamping plate 43. A third threaded rod 42 is rotatably clamped at the center of the outer surface of the arc-shaped clamping plate 43. Limiting guide columns 41 are arranged on the outer surfaces of both ends of the arc-shaped clamping plate 43.

[0047] Both ends of the threaded conveying rod 15 of the present invention are rotatably clamped with the end part and the middle part of the middle end of the support frame 36, 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 part of the support frame 36 to ensure the stability of the operation of the driving motor 19. A limiting cross bar is arranged below the inside of the support frame 36. Moreover, sleeve holes adapted to the limiting cross bar are penetrated and opened at the bottoms of both end faces of the pushing frame 11. Therefore, one end of the pushing frame 11 is slidably sleeved with the limiting guide rod through the first socket hole 14, which can play a role in limiting the sliding of the pushing frame 11.

[0048] The transmission shaft 22 of the present invention is rotatably connected with the edges on both sides of the first threaded rod 38 at the top of the supporting 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 gear shafts 29 on both sides of the middle part of the supporting 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 gear shaft 29 are rotatably connected with the middle part of the supporting frame 36 through the limiting plug hole 32, so as to limit the rotation of the gear shaft 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 gear shaft 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] Working principle of the present invention: When recycling waste cables, first cut the long cables at equal intervals, then place the end of the cut cable on the top of the roller 112 at one end of the pushing frame 11, then pull the positioning pin 110 so that one end thereof is separated from the second extrusion head 16, causing the second extrusion head 16 to deflect to the side, and then push the cable to be centered and inserted between the clamping members 4. 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 inserted into the interior between the clamping members 4. Then pull the positioning pin 110 to slide and compress the tension spring 111 to contract, and then pull the second extrusion head 16 to reset and flip. At the same time, the end of the second extrusion head 16 will be aligned and in contact with the end of the cable. At the same time, remove the external force of the positioning pin 110, so that one end of the positioning pin 110 is inserted and positioned with the end face of the second extrusion head 16. Then start the driving motor 19 to drive the threaded conveying rod 15 to rotate through the transmission chain 18, thereby driving the entire pushing frame 11 to slide inside the support frame 36. At the same time, the pushing frame 11 will push the end of the cable towards the middle of the support frame 36 through the second extrusion head 16 at one end of the top, so that the end of the cable enters between the upper feeding pressure roller 315 and the double-edge cutting knife 314, and the upper and lower protective layers of the end face of the cable contact the upper and lower double-edge cutting knives 314 in the middle of the support frame 36. Therefore, the double-edge 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 will slide to both sides under the block of the vertical guide plate 312, and the copper wire in the middle will continue to move towards the other end of the support frame 36 through the arc-shaped groove 311 until the entire cable is completely skinned. At the same time, the protective layer outside the cable will fall on both sides in the middle of the support frame 36, and the internal copper wire will slide into the internal of the other end storage box 31 for collection;

[0052] Among them, when the cable is pushed into contact with the lower feeding pressure roller 316, it will drive the lower feeding pressure roller 316 to rotate under the action of friction, and the lower feeding pressure roller 316 will drive another set of lower feeding pressure rollers 316 to rotate synchronously through the transmission gears 317 and transmission belts 318 at both ends. Therefore, after the copper wire passes through the middle of the vertical guide plate 312 through the arc-shaped groove 311, the copper wire will overlap on the upper surface of the lower feeding pressure roller 316 at the other end, and the lower feeding pressure roller 316 will continue to drive the copper wire to slide forward under the friction of the rubber layer on the outer surface until the copper wire falls into the internal of the storage box 31 for collection;

[0053] Among them, while the pushing frame 11 is moving, it will drive a set of gear shafts 29 that are disengaged from the cable engagement to rotate through the driving tooth groove 12 at one end. At the same time, the gear shafts 29 will drive the second winding disc 210 to wind the connecting rope 26 through the ratchets 28 and pawls 27 at both ends, so that the connecting rope 26 pulls the polishing frame 24 at the top to descend. At the same time, the knife grinding groove 211 in the middle of the polishing frame 24 will descend along the cutting edge of the double-edge cutting knife 314. When the knife grinding groove 211 descends to the bottommost end, the stripped copper wire will pass through the arc-shaped groove 311 and overlap on the upper surface of the lower feeding pressure roller 316. At this time, the polishing frame 24 is located below the copper wire, and the gear shaft 29 will also be separated from the driving tooth groove 12 on the upper surface of the pushing frame 11. Therefore, the transmission shaft 22 will drive the first winding discs 23 at both ends to wind the connecting rope 26 under the elastic force of the torsion spring 21, so as to drive the polishing frame 24 to rise and contact the bottom of the copper wire. Until the copper wire completely slides into the storage box 31 inside, the polishing frame 24 rises and resets without obstruction, so as to polish the double-edge cutting knife 314 for the second time to ensure the sharpness of the double-edge cutting knife 314;

[0054] When the pushing frame 11 moves to the other end, it can pull the positioning pin 110 at the edge of the first extrusion head 13 to slide and squeeze the tension spring 111 to contract, then pull the first extrusion head 13 to flip, and then insert the cable between the clamping components 4 by the same operation. Then pull the first extrusion head 13 to reset and flip. At the same time, the end of the first extrusion head 13 will be aligned and in contact with the end of the cable. At the same time, remove the external force on the positioning pin 110, so that one end of the positioning pin 110 is inserted and positioned with the end face of the second extrusion head 16. Then continue to control the driving motor 19 to rotate in the reverse direction, so as to drive the pushing frame 11 to slide back inside the support 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 inside the other end for collection. Moreover, it will also drive another set of polishing components 2 to polish the double-edge cutting knife 314 on the other side, so as to ensure that the double-edge cutting knives 314 on both sides remain sharp;

[0055] The ratchet 28 at the end of the gear shaft 29 is engaged with the pawl 27. Therefore, when the pushing frame 11 slides back, it will not drive the second winding disc 210 to wind the connecting rope 26, so as to ensure the normal cutting and processing of the cable. Therefore, through the coordinated operation of the extrusion component 1, the polishing component 2, the limiting component 3 and the clamping component 4, the cable can be automatically cut, and at the same time, the protective layer and the copper wire of the cable can be separated and collected. Moreover, during the cutting process, the double-edge cutting knife 314 can be polished to ensure the sharpness of the double-edge cutting knife 314, and the cable can be efficiently cut, processed and recycled to meet people's use requirements.

[0056] The above has described in detail an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
