Description

Technical Field

[0001] The present invention relates to the technical field of cable stripping, and in particular to a cable stripping device for cable recycling. Background Art

[0002] Cables are a general term for items such as optical cables and electric cables. Cables have many uses, mainly for controlling installations, connecting devices, transmitting electricity, and other multiple functions. They are a common and indispensable thing in daily life. At present, when dealing with waste power supply cables, the cables need to be stripped, and then the internal cable cores are recycled.

[0003] In the prior art, when stripping the recycled cables, most of them complete the cable stripping work by manually holding a knife to cut the cable skin. However, manually stripping the cables not only has low efficiency, but also the knife is easy to scratch the staff, and the risk factor is relatively high. Summary of the Invention

[0004] This application provides a cable stripping device for cable recycling, which can automatically strip the cables, reduce the trouble of manual stripping, and improve work efficiency.

[0005] A cable stripping device for cable recycling provided by this application adopts the following technical solutions: A cable stripping device for cable recycling includes a base; a housing is horizontally arranged on the base; both ends of the housing are open, and a set of cutting mechanisms are arranged on the inner side wall of the outlet end of the housing; the cutting mechanism includes a first electric push rod; the first electric push rod is installed on the inner wall of the housing, and a blade holder is installed at the output end of the first electric push rod; a cutting motor is installed on the outer wall of the blade holder; the output end of the cutting motor is coaxially fixed with a cutting blade located inside the blade holder; a feeding mechanism is arranged on the inner wall of the inlet end of the housing; the feeding mechanism can convey the cable to pass through the middle position of a set of cutting blades.

[0006] By adopting the above technical solutions, when stripping the cable, the cable is fed into the housing from the inlet end of the housing, and the cable is conveyed by the feeding mechanism arranged in the housing. When one end of the cable approaches the outlet end of the housing, the first electric push rod is started to drive the blade holder and the cutting blade to move towards the direction close to the cable, and the cutting depth of the cutting blade is adjusted. Then the cutting motor is started to drive the cutting blade to rotate. When the cable is conveyed to pass through the middle position of a set of cutting blades, the rotating cutting blade cuts the cable skin, and the cable is automatically stripped.

[0007] Preferably, the feeding mechanism includes a first support frame, a second support frame and a moving assembly; the first support frame is arranged inside the shell, and a plurality of rotating rollers are horizontally rotatably connected to the inner wall of the first support frame; the second support frame is arranged inside the shell, the second support frame is located on the top of the first support frame, a plurality of driving rollers are horizontally rotatably connected to the inner wall of the second support frame, and a power assembly that can rotate the plurality of driving rollers is arranged on the outer wall of the second support frame; the moving assembly is arranged inside the shell, and the moving assembly can drive the first support frame and the second support frame to move toward or away from each other in the vertical direction.

[0008] By adopting the above technical solution, one end of the cable to be stripped is extended into the middle position of the first support frame and the second support frame, and the moving component drives the first support frame and the second support frame to move toward each other, so that the cable is clamped between the rotating roller and the driving roller, and then the power component drives the multiple driving rollers on the second support frame to rotate. The cable is pushed forward under the action of friction, so as to force the cable to pass through the middle position of a group of cutting blades for stripping.

[0009] Preferably, the power assembly includes a drive motor and a chain; the drive motor is installed on the outer wall of the second support frame, and the output end of the drive motor is coaxially fixed to the end of the drive roller located at one end of the second support frame; the ends of the multiple drive rollers away from the drive motor are coaxially fixed with sprockets; the chain is arranged on the outside of the multiple sprockets to drive the multiple sprockets to work in conjunction.

[0010] By adopting the above technical solution, when the cable is clamped in the middle position between the rotating roller and the driving roller, the driving motor is started to drive the driving roller located at one end of the second support frame to rotate. With the cooperation of the chain and multiple sprockets, multiple driving rollers rotate synchronously, and the cable is pushed forward under the action of friction force, so as to realize automatic cable conveying and feeding.

[0011] Preferably, the moving assembly includes a first motor and a screw; the first motor is mounted on the top surface of the shell; the screw is vertically rotatably connected to the inner wall of the shell, the top end of the screw is coaxially fixed to the output end of the first motor, and a pair of slides that cooperate with the screw thread transmission are sleeved on the outer wall of the screw; the pair of slides are both slidably matched with the inner wall of the shell, and the ends of the two slides away from the inner wall of the shell are respectively fixed to the first support frame and the second support frame; the threads on the outer wall of the screw that cooperate with the two slides are symmetrically arranged.

[0012] By adopting the above technical solution, when the first motor is started to drive the screw rod to rotate, the two slides mounted on the screw rod will move toward or away from each other, thereby adjusting the distance between the first support frame and the second support frame, so that cables of different diameters can be placed between the first support frame and the second support frame for transportation.

[0013] Preferably, a pair of limiting mechanisms are arranged inside the housing; the pair of limiting mechanisms are respectively located outside both sides of the first support frame along the axis direction of the housing. The limiting mechanism includes two second electric push rods, and the two second electric push rods are horizontally installed on the inner side walls of the two sides of the housing respectively. A limiting roller is vertically and rotatably connected to the output end of each second electric push rod.

[0014] By adopting the above technical solution, when automatically conveying the cable, the second electric push rods located on both sides of the cable are started to drive the limiting rollers to move and contact the outer wall of the cable. The cable being conveyed is guided and limited by the limiting rollers located on both sides of the cable, reducing the possibility of the cable shifting during the conveying process, thereby improving the accuracy of the cutting blade when cutting the cable skin.

[0015] Preferably, a ring body is vertically and fixedly connected to the top surface of the base near the cable outlet end of the housing; a ring pipe is fixedly connected to the end surface of the ring body close to the housing; a plurality of nozzles communicating with the ring pipe are fixedly connected to the outer wall of the ring pipe; the plurality of nozzles are all arranged obliquely towards the axis of the housing; a blowing component capable of supplying gas into the ring pipe is arranged on the base; a through port is arranged on the top surface of the base at the middle position between the housing and the ring body, and a material receiving box is arranged at the position corresponding to the through port at the bottom of the base.

[0016] By adopting the above technical solution, after the cable extends out from the cable outlet end of the housing, a notch is cut on the cable skin. The cable skin with the cut notch is dragged downwards to droop, and then the blowing component blows air into the ring pipe, and the gas is sprayed through the nozzles on the contact part between the cable core and the cable skin with the cut notch, promoting the separation of the cable skin from the cable core, reducing the possibility of the cable skin adhering to the outside of the cable core, and promoting the gradual peeling off of the cable skin into the material receiving box for collection.

[0017] Preferably, the blowing component includes a pump body; the pump body is installed on the top surface of the base. An air inlet pipe communicating with the external environment is fixedly connected to the input end of the pump body, and an air outlet pipe communicating with the ring pipe is fixedly connected to the output end of the pump body.

[0018] By adopting the above technical solution, the pump body is started to suck external air from the air inlet pipe and then convey the gas into the ring pipe through the air outlet pipe, thereby conveniently realizing the work of blowing gas into the ring pipe. The magnitude of the blowing wind force can be adjusted by the pump body according to needs.

[0019] Preferably, a rotating ring is coaxially and rotatably connected to the end surface of the ring body far from the ring pipe; a concave frame is installed on the end surface of the rotating ring far from the ring body; a second motor is installed on the outer wall of the concave frame; a winding roller located inside the concave frame is coaxially and fixedly connected to the output end of the second motor; a thin wire is wound around the outer wall of the winding roller; a driving component capable of driving the rotating ring to rotate is arranged on the outer wall of the ring body.

[0020] By adopting the above technical scheme, when the stripped cable core moves into the fixed ring and the rotating ring, the thin wire wound on the winding roller is pulled out, and the output end of the thin wire is wound and fixed on the outside of the multi-strand cable core. As the cable is continuously fed for stripping, the cable core gradually moves forward and passes through the rotating ring. In the process of the cable core passing through the rotating ring, the driving assembly drives the rotating ring to rotate, and starts the second motor to drive the winding roller to pay out the wire, causing the thin wire to be wound around the outside of the multi-strand cable core to gather the cable core, thereby reducing the possibility of the cable core scattering after the cable stripping is completed, and facilitating the collection and sorting by the staff.

[0021] Preferably, the driving assembly includes a third motor and a ring gear; the ring gear is coaxially fixed to the outer wall of the rotating ring; the third motor is installed on the outer wall of the ring body, and a gear is coaxially fixed to the output end of the third motor; the gear is meshed with the ring gear.

[0022] By adopting the above technical solution, the third motor is started to drive the gear to rotate, and the rotating ring rotates under the meshing cooperation of the gear and the gear ring, so that the thin wire can be wrapped around the outside of the cable core to gather the multiple cable cores.

[0023] Preferably, support rollers are provided on the top surface of the base near both ends.

[0024] By adopting the above technical solution, the support rollers located at both ends of the base can be used to lay cables and cable cores, thereby reducing the trouble of manually lifting the cables and cable cores.

[0025] In summary, this application has the following beneficial effects: 1. Feed the cable into the housing and automatically convey the cable through the feeding mechanism. When one end of the cable approaches the outlet of the housing, start the first electric push rod to drive the blade holder and the cutting blade to move to adjust the cutting depth of the cutting blade, and then start the cutting motor to drive the cutting blade to rotate. When the cable is conveyed and passes through the middle position of a group of cutting blades, the rotating cutting blade cuts the cable skin and automatically strips the cable, reducing the trouble of manual stripping and improving the efficiency of cable stripping. 2. During the automatic transmission of the cable, the second electric push rods on both sides of the cable are started to drive the limit rollers to contact the cable. The limit rollers on both sides of the cable cooperate with each other to guide and limit the conveyed cable, thereby reducing the possibility of cable deviation during the transmission process and improving the accuracy of the cutting blade when cutting the cable surface. 3. When the cable extends from the outlet end of the shell, a notch is cut on the cable skin. The notched cable skin is dragged downward and then blown into the ring tube by the blowing assembly. The gas is sprayed through the nozzle on the contact part between the cable core and the notched cable skin, so as to separate the cable skin from the cable core and reduce the possibility of the cable skin adhering to the outside of the cable core.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0029] The present invention discloses a peeling device for cable recycling, as shown in Figure 1 and Figure 2As shown, it includes a base 1, a shell 2 and a feeding mechanism 4. The shell 2 is horizontally installed on the top surface of the base 1. The shell 2 is a square shell with both ends open. One end of the shell 2 is the input end and the other end is the output end. Four cutting mechanisms 3 are arranged on the inner wall of the output end of the shell 2. The four cutting mechanisms 3 are evenly distributed on the four inner walls of the output end of the shell 2. The cutting mechanism 3 includes a first electric push rod 31, a blade holder 32 and a cutting blade 34. The first electric push rod 31 is installed on the inner wall of the output end of the shell 2. The output end of the first electric push rod 31 is arranged toward the axis of the shell 2. The blade holder 32 is fixedly connected to the output end of the first electric push rod 31. A cutting motor 33 is installed on the outer wall of the blade holder 32. The cutting blade 34 is rotatably connected to the inner wall of the blade holder 32. One end of the cutting blade 34 is coaxially fixedly connected to the output end of the cutting motor 33. The feeding mechanism 4 is arranged inside the shell 2 near the input end of the shell 2. The feeding mechanism 4 can convey the cable through the output end of the shell 2.

[0030] The cable is fed into the shell 2 from the inlet end of the shell 2, and the feeding mechanism 4 conveys the cable. When one end of the cable approaches the outlet end of the shell 2, the first electric push rod 31 is started to drive the cutting blade 34 to move toward the direction close to the cable, and the insertion depth of the cutting blade 34 is adjusted. The cutting motor 33 is started to drive the cutting blade 34 to rotate. When the cable is fed and passes through the middle position of the four cutting blades 34, the rotating cutting blade 34 cuts the cable skin to realize automatic cable stripping.

[0031] like Figure 2 and Figure 3 As shown, the feeding mechanism 4 includes a first support frame 41, a second support frame 42 and a moving assembly 43, the first support frame 41 is horizontally arranged inside the housing 2, a plurality of rotating rollers 411 are horizontally rotatably connected to the inner wall of the first support frame 41, the second support frame 42 is arranged on the top of the first support frame 41, a plurality of driving rollers 421 are horizontally rotatably connected to the inner wall of the second support frame 42, and a power assembly 44 that can rotate the plurality of driving rollers 421 is arranged on the outer wall of the second support frame 42; The power assembly 44 includes a driving motor 441 and a chain 442. The driving motor 441 is installed on the outer wall of the second support frame 42. The output end of the driving motor 441 is coaxially fixed to the end of the driving roller 421 located at one end of the second support frame 42. The end of each driving roller 421 away from the driving motor 441 is coaxially fixed to a sprocket 443 located outside the second support frame 42. The chain 442 is sleeved on the outside of multiple chains 442 to drive multiple sprockets 443 to work together. The moving assembly 43 is arranged inside the shell 2. The moving assembly 43 can drive the first support frame 41 and the second support frame 42 to move toward or away from each other in the vertical direction.

[0032] Insert one end of the cable into the middle position between the first support frame 41 and the second support frame 42. Drive the first support frame 41 and the second support frame 42 to move towards each other through the moving component 43, so that the cable is clamped between the rotating roller 411 and the driving roller 421. Then start the driving motor 441 to drive the multiple driving rollers 421 on the second support frame 42 to rotate. The cable is pushed forward under the action of friction, prompting the cable to automatically feed through the outlet end of the housing 2 for peeling treatment.

[0033] As Figure 2 and Figure 4 shown, the moving component 43 includes a first motor 431 and a lead screw 432. The first motor 431 is vertically installed on the top surface of the housing 2. The first motor 431 is a brake motor. The lead screw 432 is vertically rotatably connected to the inner wall of the bottom end of the housing 2. The top end of the lead screw 432 is coaxially fixed to the output end of the first motor 431. A pair of sliding plates 433 that are slidably matched with the inner wall of the housing 2 are sleeved on the outer wall of the lead screw 432. The end portions of the two sliding plates 433 away from the inner wall of the housing 2 are respectively fixed to the outer walls of the first support frame 41 and the second support frame 42. The lead screw 432 is in threaded transmission cooperation with the two sliding plates 433. The threads of the lead screw 432 cooperating with the two sliding plates 433 are arranged in symmetric threads.

[0034] Start the first motor 431 to drive the lead screw 432 to rotate, prompting the two sliding plates 433 sleeved on the lead screw 432 to move towards each other or away from each other, and adjust the distance between the first support frame 41 and the second support frame 42, so as to be able to place cables with different diameters between the first support frame 41 and the second support frame 42 for conveying.

[0035] As Figure 2 and Figure 5 shown, a pair of limiting mechanisms 21 are arranged in the housing 2 respectively outside both ends of the first support frame 41 along the axial direction of the housing 2. The limiting mechanism 21 includes two second electric push rods 211. The two second electric push rods 211 are respectively horizontally installed on the two inner side walls of the housing 2. The two second electric push rods 211 are located outside both sides of the cable. The output end of each second electric push rod 211 is rotatably connected with a vertically arranged limiting roller 212. The second electric push rod 211 drives the limiting roller 212 to contact the cable.

[0036] When the cable is being conveyed forward, start the second electric push rods 211 located on both sides of the cable, so that the limiting rollers 212 located outside the cable contact the outer wall of the cable. The cable is guided and limited through the cooperation of the limiting rollers 212 on both sides of the cable, reducing the possibility of the cable shifting during the conveying process and improving the accuracy when cutting the cable skin.

[0037] As Figure 1 and Figure 6As shown in the figure, a ring body 5 close to the wire outlet end of the housing 2 is vertically fixed to the top surface of the base 1 through a support rod. A ring pipe 51 is fixed to the end surface of the ring body 5 close to the housing 2. A plurality of nozzles 511 communicating with the ring pipe 51 are fixed to the outer wall of the ring pipe 51. Each nozzle 511 is arranged obliquely towards the axis of the housing 2. A blowing assembly 52 for supplying gas into the ring pipe 51 is arranged on the base 1. The blowing assembly 52 includes a pump body 521, an air inlet pipe 522 and an air outlet pipe 523. The pump body 521 is installed on the top surface of the base 1. One end of the air inlet pipe 522 is fixed to the input end of the pump body 521, and the other end communicates with the external environment. One end of the air outlet pipe 523 is fixed to the output end of the pump body 521, and the other end is fixed to the outer wall of the ring pipe 51 and communicates with the ring pipe 51.

[0038] After the cable extends out from the wire outlet end of the housing 2, a notch is cut on the cable skin. The cable skin with the cut notch is dragged downward to make it droop. Then, the pump body 521 is started to blow air into the ring pipe 51, and the gas is blown through the nozzles 511 onto the contact part between the cable core and the cable skin with the cut notch, so as to separate the cable skin from the cable core and reduce the possibility of the cable skin adhering to the outside of the cable core.

[0039] As Figure 1 and Figure 6 shown in the figure, a through hole 11 is arranged on the top surface of the base 1 at the middle position between the housing 2 and the ring body 5. A material receiving box 12 is arranged at the bottom of the base 1, and the material receiving box 12 corresponds to the position of the through hole 11.

[0040] The material receiving box 12 arranged at the bottom of the base 1 can be used to collect the drooping cable skin, so that the staff can centrally process the peeled cable skin.

[0041] As Figure 6 and Figure 7 shown in the figure, a rotating ring 6 is coaxially rotatably connected to the end surface of the ring body 5 far from the ring pipe 51. A concave frame 61 is installed on the end surface of the rotating ring 6 far from the ring body 5. A second motor 62 is installed on the outer wall of the concave frame 61. The output end of the second motor 62 is coaxially fixed with a winding roller 63 located inside the concave frame 61. The winding roller 63 is rotationally matched with the inner wall of the concave frame 61. A thin wire 64 is wound around the outer peripheral surface of the winding roller 63. A driving assembly 65 for driving the rotating ring 6 to rotate is further arranged on the outer wall of the ring body 5. The driving assembly 65 includes a third motor 651, a gear ring 652 and a gear 653. The third motor 651 is installed on the outer wall of the ring body 5. The gear 653 is coaxially fixed to the output end of the third motor 651. The gear ring 652 is coaxially fixed to the outer wall of the rotating ring 6, and the gear ring 652 meshes with the gear 653.

[0042] When the skinned cable core moves into the fixed ring and the rotating ring 6, the thin wire 64 wound around the winding roller 63 is drawn out and wound and fixed outside the multi-strand cable core. As the cable is continuously skinned and fed, the cable core gradually moves forward through the rotating ring 6. During the process of the cable core passing through the rotating ring 6, the third motor 651 is started, and the rotating ring 6 is driven to rotate through the meshing of the gear 653 and the gear ring 652, and the second motor 62 is started to drive the winding roller 63 to pay out the wire, so that the thin wire 64 is wound around the multi-strand cable core to gather the cable core, reducing the possibility of the cable core spreading after cable skinning is completed, so as to facilitate the staff to collect and sort out the cable core.

[0043] As Figure 1 and Figure 7 shown, two support rollers 13 are horizontally and rotatably connected to the top surface of the base 1. One of the two support rollers 13 is located outside the side close to the wire inlet end of the housing 2, and the other support roller 13 is located outside the side of the rotating ring 6 away from the ring body 5.

[0044] The support roller 13 located close to the wire inlet end of the housing 2 can be used to support the fed and conveyed cable, and the support roller 13 located close to the rotating ring 6 can be used to support the wound cable core, thus reducing the trouble of manually lifting the cable and the cable core.

[0045] Working principle: When skinning the cable, one end of the cable is inserted into the middle position between the first support frame 41 and the second support frame 42. The first motor 431 is started to drive the lead screw 432 to rotate, and the two sliding plates 433 sleeved on the lead screw 432 drive the first support frame 41 and the second support frame 42 to move towards each other, so that the end of the cable is clamped between the rotating roller and the driving roller 421. Then, the driving motor 441 is started to drive the multiple driving rollers 421 on the second support frame 42 to rotate, and the cable is pushed forward under the action of friction force to realize the automatic feeding and conveying work of the cable; when the cable is fed and conveyed, the second electric push rod 211 located outside both sides of the cable is started to drive the limiting roller 212 to move and contact the outer wall of the cable, and the cable is guided and limited through the cooperation of the limiting rollers 212 located outside both sides of the cable, reducing the possibility of the cable deviating during the feeding and conveying process; When one end of the fed and conveyed cable approaches the wire outlet end of the housing 2, the first electric push rod 31 is started to drive the blade holder 32 and the cutting blade 34 to move towards the direction close to the cable. After adjusting the cutting depth of the cutting blade 34, the cutting motor 33 is started to drive the cutting blade 34 to rotate. When the cable is conveyed and passes through the middle position of a group of cutting blades 34, the rotating cutting blade 34 cuts open the cable skin; After the cable extends from the wire outlet end of the housing 2, a notch is cut in the cable skin. The cable skin with the cut notch is dragged downward and allowed to hang. The pump body 521 is activated to blow air into the annular pipe 51. The gas blown into the annular pipe 51 is blown through the nozzle 511 onto the contact part between the cable core and the cable skin with the cut notch, promoting the separation of the cable skin from the cable core and reducing the possibility of the cable skin adhering to the outside of the cable core, so that the cable skin gradually peels off and enters the material receiving box 12 for collection.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
