Description

Technical Field

[0001] This invention belongs to the field of material recycling technology, specifically referring to a waste cable recycling and processing device. Background Technology

[0002] Currently, cable insulation stripping is a core process in power construction and waste cable recycling. The industry mainstream adopts a fixed blade spacing stripping structure with circumferential cutting and longitudinal cutting, or a full-diameter adaptive floating blade structure, which strips the insulation by directly cutting through the insulation layer. However, the current technology generally requires the blade feed depth to exceed the nominal thickness of the insulation layer. During the operation, the blade is very likely to directly contact and scratch the copper core. In the waste recycling scenario, this will lead to an increase in copper loss rate, a decrease in the purity and economic value of recycled copper, and leave electrical safety hazards. It cannot completely avoid the problem of copper core scratches and has extremely poor adaptability to thin-insulated, small-diameter cables.

[0003] Therefore, developing a stripping device that can completely avoid scratching the copper core with the blade, has high stripping efficiency, and is highly adaptable to cables has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a waste cable recycling and processing device, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a waste cable recycling and processing device, including a base, a cutting mechanism, a guiding mechanism and a positioning mechanism. The base includes a bottom plate. The cutting mechanism is symmetrically arranged above the bottom plate. The guiding mechanism is slidably arranged on one side of the cutting mechanism. The positioning mechanism is slidably arranged on the other side of the cutting mechanism. The cutting mechanism is symmetrically arranged.

[0006] Furthermore, the top of the base plate is provided with a sliding groove 1 and a sliding groove 2. The sliding groove 1 is located on one side of the cutting mechanism, and the sliding groove 2 is located on the other side of the cutting mechanism. A bidirectional screw 1 is rotatably installed in the sliding groove 1. An operating knob 1 is provided on the side wall of the base plate. The operating knob 1 is drivenly connected to the bidirectional screw 1. A hexagonal groove 1 is provided on the operating knob 1. A bidirectional screw 2 is rotatably installed in the sliding groove 2. An operating knob 2 is also provided on the side wall of the base plate. The operating knob 2 is drivenly connected to the bidirectional screw 2. A hexagonal groove 2 is provided on the operating knob 2.

[0007] Furthermore, the guiding mechanism includes a slider and a guide plate. The slider is slidably disposed in a groove and has a threaded hole that engages with a bidirectional screw. The guide plate is disposed on the top of the slider and is inclined.

[0008] The inclined guide plate can expand the cable insulation layer after it has been cut by the cutting mechanism to both sides during the transportation process, so that the copper core is separated from the insulation layer.

[0009] Furthermore, the positioning mechanism includes a positioning plate and a second slider. The second slider has a threaded hole that engages with the threaded double screw. The positioning plate is located on the top of the second slider.

[0010] Furthermore, a threaded hole is provided on the top of the base plate, the threaded hole being located between the positioning mechanisms, and a threaded knob is rotatably provided inside the threaded hole.

[0011] The positioning plate and threaded knob can guide the cable through limiting, so that the cable is positioned during transportation.

[0012] Furthermore, the cutting mechanism includes a base with a receiving groove at the bottom. A cutting blade is hinged within the receiving groove, with the hinge point of the cutting blade located at the front end of the receiving groove. An expansion chamber is located at the top of the rear end of the base, communicating with the receiving groove. A trigger rod is hinged within the expansion chamber, with its hinge point located within the expansion chamber. The length of the trigger rod extending beyond the receiving groove is greater than the length of the blade extending beyond the receiving groove. A positioning groove is located on the side of the trigger rod near the cutting blade. The cutting blade includes a hinge rod and a blade head, with the blade head located at the bottom of the hinge rod. The positioning groove is fitted to the rear end of the hinge rod. In the initial state, the rear end of the hinge rod is engaged in the positioning groove. A spring is located within the expansion chamber, connected to the hinge rod. When the spring is in a balanced state, the hinge rod is in the position engaged with the positioning groove.

[0013] The cutting edge of the blade is set at an angle.

[0014] The hinge rod has a through hole at the end away from the trigger rod, and a retaining shaft is provided in the receiving groove. The retaining shaft is located inside the through hole.

[0015] The trigger rod has a through hole two at one end inside the expansion chamber, and a retaining shaft two is provided inside the expansion chamber. The retaining shaft two is located inside the through hole two, and the retaining shaft two is press-fitted with the through hole two.

[0016] Furthermore, the base is symmetrically provided with extension rods on both sides, and the top of one side extension rod of the bottom positioning mechanism is provided with a sliding rod, and the top of the other side extension rod of the bottom positioning mechanism is rotatably provided with a threaded rod. A sliding hole is opened on one side extension rod of the top positioning mechanism, and a second threaded hole is opened on the other side extension rod of the top positioning mechanism. The sliding hole fits with the sliding rod, and the second threaded hole is threadedly engaged with the threaded rod.

[0017] The beneficial effects of this invention using the above structure are as follows: This solution provides a waste cable recycling and processing device. After adjusting the spacing of the guide mechanism, the spacing of the cutting mechanism, and the height of the threaded knob according to the cable specifications, when the cable is conveyed to the cutting mechanism, the cutting blade will cut the insulation layer of the cable. When the cable's starting end passes the cutting blade, the cutting blade will completely cut the insulation layer, exposing the copper core. When the cable end touches the trigger rod, it will push the trigger rod away. After losing the limitation of the positioning groove, the cable will squeeze the cutting blade to both sides during the conveying process, and the blade head will slightly retract into the receiving groove. With a larger gap between the two cutting heads, the insulation layer cannot be completely cut. The incompletely cut insulation layer acts as a thin protective layer on the copper core. After cutting, the insulation layer can be easily torn apart by the guide mechanism, thus peeling off the copper core. Compared with the traditional one-time cutting method, this method of incomplete cutting followed by physical tearing and separation means that the cutting head may only damage the copper core in the initial stage of cutting. In the rest of the process, the cutting head will only cut the insulation layer and will never come into contact with the copper core, thus preventing damage to the copper core. This method can effectively improve the quality of cable recycling. Attached Figure Description

[0023] like Figures 1-6 As shown, the present invention provides a waste cable recycling and processing device, including a base 1, a cutting mechanism 2, a guiding mechanism 3 and a positioning mechanism 4.

A bidirectional screw 103 is rotatably installed in the sliding groove 102. An operating knob 104 is provided on the side wall of the base plate 101. The operating knob 104 is connected to the bidirectional screw 103. A hexagonal groove 105 is provided on the operating knob 104.

[0026] The inclined guide plate 301 can expand the cable insulation layer after it has been cut by the cutting mechanism 2 to both sides during the transportation process, so that the copper core is separated from the insulation layer.

[0027] The positioning mechanism 4 includes a positioning plate 401 and a slider 402. The slider 402 has a screw hole that engages with the bidirectional screw 107. The positioning plate 401 is located on the top of the slider 402.

[0028] The top of the base plate 101 is provided with a threaded hole 110, which is located between the positioning mechanisms 4. A threaded knob 111 is rotatably provided inside the threaded hole 110.

[0029] The positioning plate 401 and the threaded knob 111 can guide the cable through limiting, so that the cable is positioned during the transportation process.

[0030] The cutting mechanism 2 includes a base 201, with a receiving groove 202 at the bottom of the base 201. A cutting blade 204 is hinged within the receiving groove 202, with the hinge point of the cutting blade 204 located at the front end of the receiving groove 202. An extension chamber 203 is located at the top of the rear end of the base 201, communicating with the receiving groove 202. A trigger rod 207 is hinged within the extension chamber 203, with the hinge point of the trigger rod 207 located within the extension chamber 203. The length of the trigger rod 207 extending outside the receiving groove 202 is greater than the length of the blade head 206 extending into the receiving groove 202. The trigger rod 207 has a positioning groove 208 on the side near the cutting blade 204. The cutting blade 204 includes a hinge rod 205 and a blade head 206. The blade head 206 is located at the bottom of the hinge rod 205. The positioning groove 208 is in contact with the tail end of the hinge rod 205. In the initial state, the tail end of the hinge rod 205 is locked in the positioning groove 208. A spring 209 is provided in the expansion chamber 203. The spring 209 is connected to the hinge rod 205. When the spring 209 is in a balanced state, the hinge rod 205 is in the position where it is locked with the positioning groove 208.

[0031] The hinge rod 205 has a through hole 210 at the end away from the trigger rod 207, and a retaining shaft 211 is provided in the receiving groove 202. The retaining shaft 211 is located inside the through hole 210.

[0032] Among them, the trigger rod 207 has a through hole 212 at one end inside the expansion chamber 203, and a retaining shaft 213 is provided inside the expansion chamber 203. The retaining shaft 213 is located inside the through hole 212, and the retaining shaft 213 and the through hole 212 are interference fit.

[0033] Furthermore, the base 201 is symmetrically provided with extension rods 214 on both sides. The top of one side extension rod 214 of the bottom positioning mechanism 4 is provided with a slide rod 217, and the top of the other side extension rod 214 of the bottom positioning mechanism 4 is rotatably provided with a threaded rod 218. The one side extension rod 214 of the top positioning mechanism 4 is provided with a sliding hole 215, and the other side extension rod 214 of the top positioning mechanism 4 is provided with a threaded hole 216. The sliding hole 215 fits with the slide rod 217, and the threaded hole 216 engages with the threaded rod 218.

[0034] In practical use, first adjust according to the specifications of the recycled cable. Rotate the threaded rod 218 to adjust the distance between the cutting mechanisms 2, so that the minimum spacing of the cutter heads 206 is the same as the diameter of the cable's copper core. At the same time, rotate the bidirectional screw 107 by operating knob 108. The bidirectional screw 107 adjusts the spacing between the positioning plates 401 to fit the overall diameter of the cable. Then, rotate the threaded knob 111 to adjust its height to support the bottom of the cable, so that the cable's axis fits the axis of symmetry of the cutter head 206. Subsequently, rotate the bidirectional screw 107 by operating knob 104. The bidirectional screw 107 adjusts the spacing between the guide plates 301 (the function of the guide plates 301 is to separate and peel the insulation layer of the cut cable to both sides; the spacing of the guide plates 301 can be determined by comprehensively considering the cable specifications, insulation layer thickness, and insulation layer flexibility). Finally, confirm the hinge of the positioning mechanism 4. After the rod 205 is inserted into the positioning slot 208, the cable can be fed. Initially, the spacing between the cutter heads 206 is the smallest, and the copper core is completely exposed after the cable head is cut by the cutter head 206. As the cable is fed, after the cable head contacts the trigger rod 207, the cable pushes the trigger rod 207 away, and the tail end of the hinge rod 205 disengages from the positioning slot 208. After losing its limit, the cutting blade 204 is squeezed and pushed to both sides until the hinge rod 205 is in contact with the receiving slot 202. The spacing between the cutter heads 206 becomes larger, and the insulation layer of the cable cannot be completely cut, leaving a protective layer. This achieves the purpose of not contacting the copper core and protecting the copper core. At the same time, in the early stage of cutting, the operator pushes the insulation layer to both sides of the guide plate 301, so that the insulation layer is separated from the copper core as the cable is fed. The limit of the guide plate 301 will tear the insulation layer to both sides, so that the incompletely cut insulation layer can be easily torn apart during the cable feeding process.
