Description

Technical Field

[0001] The present invention relates to the technical field of cable stripping, and in particular to an automatic wire stripping device for cables. 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, etc., and are common and indispensable items in daily life.

[0003] When a cable cannot be used normally, in order to achieve the recyclable utilization of resources, the cable is usually stripped, and then the internal copper wire is recycled. However, when the existing stripping equipment processes waste cables, different diameter cables require different specifications of stripping cutters, and a single device is difficult to meet the needs of processing cables with different diameters.

[0004] The patent with the patent number CN220492560U discloses a stripping device for waste cable recycling, including a fixed base. One side of the top of the fixed base is provided with a lifting component. The lifting component includes telescopic rods fixed at both ends of the top of the fixed base. A support roller is installed at the top of the telescopic rod. Limiting groove plates are arranged at both ends of the top of the support roller. A conveying component is arranged in the middle of the fixed base. The conveying component includes support frames installed at both ends of the top of the fixed base. A cutting component is arranged at the other end of the top of the fixed base; the lifting component set in this invention can make the end of the cable be smoothly conveyed during stripping, avoiding the end from warping up, and the limiting groove plates arranged on both sides can limit and block both sides of the cable to avoid dropping, thereby slowing down the physical strength consumed by lifting to a certain extent and avoiding deviation. The distance between the two stripping blades is adjusted by the cutting component with adjustable spacing, so that the device can cut cables with different diameter sizes.

[0005] When the above device recycles and processes cables, it is necessary to manually adjust the distance between the extrusion tooth rollers through an adjusting screw to extrude and convey the cable, and then adjust the distance between the stripping blades through a bidirectional lead screw to strip cables with different diameters. However, all adjustment processes need to be carried out manually, and the adjustment result may not be accurate enough, resulting in the situation that the cable outer skin is not completely cut off, affecting the recycling efficiency.

[0016] The beneficial effects are as follows: 1. This device is divided into two parts: upward cable conveying and outward cable pushing. The part for upward cable conveying can push the cable upward through the rotating conveying frame and the arc-shaped pressing plate. And every time the rotating conveying frame rotates 60 degrees, the lifting lever will descend and separate the transmission gear from the driving gear through the wedge-shaped convex block. When the rotating block between the transmission gear and the driving gear is disengaged, the rotating conveying frame stops rotating. At this time, the feeding gear contacts the moving friction block, and the mechanism for outward cable pushing operates. The feeding gear is driven to rotate, and the reciprocating lead screw rotates accordingly and pushes the cable to move through the moving feeding plate. During this process, the lifting cutter cuts the cable outer sheath horizontally. After the moving feeding plate moves back to its original position, it will also cause the transmission gear to move back to its original position. The rotating conveying frame rotates again and conveys the cable upward. The structure for upward cable conveying and the structure for outward cable pushing operate alternately to quickly and automatically cut the cable outer sheath.

[0017] 2. When processing cables of the same batch, after the first cable contacts the sliding adjustment frame, the sliding adjustment frame will be pushed and slide along the arc-shaped inner shell, and then drive the lifting cutter to move up and down through components such as the swing rod and the lifting push rod to automatically adjust the height of the lifting cutter according to the cable diameter. After the initial adjustment, the locking mechanism will directly lock the sliding adjustment frame, and the height of the lifting cutter is also locked. After processing all the cables of the same batch, when the equipment is turned off, the locking mechanism will automatically release the restriction on the sliding adjustment frame, and the sliding adjustment frame will automatically move back to its original position, and components such as the lifting cutter will move back to their original positions accordingly. When processing cables next time, the height of the lifting cutter is adjusted again through the sliding adjustment frame to realize the function of automatically adjusting the cutting depth of the lifting cutter.

[0018] 3. When the cable is pushed outwards, two arc-shaped limiting plates limit the cable from both sides to prevent the cable outer sheath from spreading to both sides. During the process of the cable passing through the fixed frame, the circumferential cutting knife rotating with the circumferential cutting gear will cut the cable outer sheath circumferentially. The cut outer sheath will automatically disengage from the core and fall downward. And when the oblique cutting-in knife on the circumferential cutting knife contacts the cable outer sheath, due to the oblique contact between the oblique cutting-in knife and the circumferential cutting knife and the cable outer sheath, it can make the oblique cutting-in knife and the circumferential cutting knife cut into the cable outer sheath more smoothly.

DETAILED DESCRIPTION

[0035] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1: An automatic wire stripping device for a cable, such as Figures 1 - 15As shown in the figure, it includes a housing 1, an arc-shaped inner housing 1001, a drive shaft 101, a driving gear 102, a rotating block 103, a transmission gear 104, a conveying gear 107, a fixing plate 108, a rotating conveying frame 109, a pressing assembly, a conveying and cutting mechanism, and an adjusting mechanism. An arc-shaped inner housing 1001 is fixedly connected inside the housing 1. There is a rectangular inlet between the housing 1 and the arc-shaped inner housing 1001. The cable is fed into the rotating conveying frame 109 inside the housing 1 through the rectangular inlet. Fixing plates 108 are fixedly connected to both ends of the arc-shaped inner housing 1001. The arc-shaped inner housing 1001 and the fixing plates 108 form a cylindrical chamber. A drive shaft 101 is rotatably connected to the housing 1. The drive shaft 101 passes through the housing 1 and is connected to the fixing plate 108. A driving gear 102 is fixedly connected to the drive shaft 101. A rotating block 103 is fixedly connected to the driving gear 102. A transmission gear 104 is slidably connected to the drive shaft 101. A rotating block 103 is fixedly connected to the transmission gear 104. The rotating blocks 103 between the transmission gear 104 and the driving gear 102 can be engaged with each other. Only after the two rotating blocks 103 are engaged can the driving gear 102 drive the transmission gear 104 to rotate. A conveying gear 107 is rotatably connected to the fixing plate 108. The conveying gear 107 is always meshed with the transmission gear 104. A rotating conveying frame 109 is rotatably connected inside the two fixing plates 108. The rotating conveying frame 109 is coaxially fixedly connected to the conveying gear 107. The pressing assembly is installed inside the rotating conveying frame 109. When the rotating conveying frame 109 rotates, the cable is conveyed upward through the pressing assembly. The conveying and cutting mechanism is installed inside the housing 1. The conveying and cutting mechanism conveys the cable outward and transversely cuts the outer skin of the cable. The adjusting mechanism is installed on the housing 1 and the arc-shaped inner housing 1001. The adjusting mechanism adjusts the height of the inner cutter of the conveying and cutting mechanism according to the diameter of the cable.

[0037] When dealing with waste cables, first push the cable from the entrance between the arc-shaped inner shell 1001 and the shell 1 to the rotary conveyor rack 109. The pressing assembly presses the cable against the inner arc surface of the arc-shaped inner shell 1001. At this time, the external motor drives the driving gear 102 to rotate through the transmission shaft 101. At this time, the rotating block 103 between the driving gear 102 and the transmission gear 104 is docked together. During the rotation of the driving gear 102, the transmission gear 104 is driven to rotate through the rotating block 103. When the transmission gear 104 rotates, the rotary conveyor rack 109 is driven to rotate through the conveying gear 107. During the rotation of the rotary conveyor rack 109, the cable is driven to move upward inside the arc-shaped inner shell 1001 through the pressing assembly. After the rotary conveyor rack 109 rotates 60 degrees each time, a new cable is sent into the arc-shaped inner shell 1001 through the entrance. When the rotary conveyor rack 109 sends the cable to the highest position, the conveying and cutting assembly drives the transmission gear 104 to slide along the transmission shaft 101, so that the rotating block 103 between the transmission gear 104 and the driving gear 102 is disengaged. At this time, the transmission gear 104, the conveying gear 107 and the rotary conveyor rack 109 stop rotating. The conveying and cutting assembly operates and pushes the cable outwards from the top outlet of the shell 1. During the process of the cable being pushed out, the outer insulating skin of the cable will be transversely cut by the conveying and cutting assembly. When the conveying and cutting assembly moves back to its original position, the rotating block 103 between the driving gear 102 and the transmission gear 104 automatically engages, and the rotary conveyor rack 109 continues to rotate and convey the cable upward. During the process of conveying the cable, the rotary conveyor rack 109 drives the adjusting mechanism to operate according to the cable specifications, and then adjusts the conveying and cutting mechanism through the adjusting mechanism.

[0038] Embodiment 2: On the basis of Embodiment 1, as Figure 4 and Figure 5 shown, the pressing assembly includes a fixed rod 1091, an arc-shaped pressing plate 110 and a pressing spring 111. The fixed rod 1091 is fixedly connected inside the rotary conveyor rack 109. The arc-shaped pressing plate 110 is slidably connected to the fixed rod 1091. A pressing spring 111 is arranged between the arc-shaped pressing plate 110 and the fixed rod 1091. One end of the pressing spring 111 is fixed on the fixed rod 1091, and the other end is fixed on the arc-shaped pressing plate 110. The pressing spring 111 presses the cable through the arc-shaped pressing plate 110 to push the cable to move upward inside the arc-shaped inner shell 1001.

[0039] After the cable is pushed into the arc-shaped inner shell 1001, the cable is moved synchronously with the rotary conveyor rack 109, and finally the cable is pushed between the arc-shaped pressing plate 110 on the rotary conveyor rack 109 and the arc-shaped inner shell 1001. At this time, under the action of the pressing spring 111, the arc-shaped pressing plate 110 is in close contact with the cable. And at this time, when the rotary conveyor rack 109 rotates, the cable will be driven to move along the inner arc surface of the arc-shaped inner shell 1001 through the arc-shaped pressing plate 110 to realize the function of conveying the cable.

[0040] like Figure 3 , Figure 4 , Figures 6 - 8 and Figure 10 As shown, the conveying and cutting mechanism includes a rotating gear 2, a spline shaft 201, a movable friction block 202, a connecting frame 203, a push gear 204, a push guide frame 205, a reciprocating screw rod 206, a movable push plate 207, a lifting cutter 507 and a toggle adjustment component. The spline shaft 201 is rotatably connected in the housing 1, the rotating gear 2 is fixedly connected to the spline shaft 201, the rotating gear 2 is meshed with the driving gear 102, the movable friction block 202 is slidably connected to the spline shaft 201, the transmission gear 104 is rotatably connected to the connecting frame 203, the top of the connecting frame 203 is rotatably connected to the outside of the movable friction block 202, the push guide frame 205 is fixedly connected between the two fixed plates 108, and the push guide frame 205 is fixedly connected to the outside of the movable friction block 202. 05 is rotatably connected with a reciprocating screw rod 206, one end of the reciprocating screw rod 206 passes through the pushing guide frame 205 and is fixedly connected with a pushing gear 204. When the moving friction block 202 is pressed against the pushing gear 204, the rotating gear 2 can drive the pushing gear 204 to rotate through the spline shaft 201 and the moving friction block 202. A moving pushing plate 207 is slidably connected with the pushing guide frame 205. The moving pushing plate 207 is threadedly connected with the reciprocating screw rod 206. A lifting cutter 507 is slidably connected with the shell 1. The lifting cutter 507 cuts the cable sheath horizontally. The toggle adjustment component is installed in the shell 1. The toggle adjustment component is used to adjust the position of the moving friction block 202 through the transmission gear 104.

[0041] like Figure 3 , Figure 6 and Figure 7As shown in the figure, the toggling and transposing assembly includes a wedge-shaped protrusion 105, a spreading spring 106, a rotating lever 1081, a liquid storage tube 208, a sliding piston rod 2081, a lifting piston rod 2082, a sliding block 2083, a lifting lever 2084, a downward pressure spring 2085, a U-shaped rod 2086 and a lifting baffle 209. A wedge-shaped protrusion 105 is fixedly connected to the transmission gear 104. The wedge-shaped protrusion 105 is located at one end of the transmission gear 104 away from the rotating block 103. A spreading spring 106 is provided between the transmission gear 104 and the fixed disk 108. One end of the spreading spring 106 is fixed on the fixed disk 108, and the other end is in contact with the transmission gear 104. A rotating lever 1081 is rotatably connected inside the fixed disk 108. The rotating lever 1081 is fixedly connected to the rotating shaft of the conveying gear 107. A liquid storage tube 208 is fixedly connected to the fixed disk 108. Hydraulic oil is stored in the liquid storage tube 208. A sliding piston rod 2081 is slidably connected to the liquid storage tube 208 in the horizontal direction. The sliding piston rod 2081 passes through the movable pushing plate 207 and is slidably connected thereto. A lifting piston rod 2082 is slidably connected to the liquid storage tube 208 in the vertical direction. A sliding block 2083 is fixedly connected to the top of the lifting piston rod 2082. The sliding block 2083 is slidably connected to the fixed disk 108. A lifting lever 2084 is fixedly connected to the sliding block 2083. A U-shaped rod 2086 is fixedly connected outside the fixed disk 108. The sliding block 2083 is slidably connected to the U-shaped rod 2086. A downward pressure spring 2085 is provided between the U-shaped rod 2086 and the sliding block 2083. One end of the downward pressure spring 2085 is fixed on the sliding block 2083, and the other end is fixed on the U-shaped rod 2086. A lifting baffle 209 is slidably connected inside the movable pushing plate 207. The lifting baffle 209 is used to limit the sliding piston rod 2081. During the rotation of the rotating lever 1081, the lifting baffle 209 will be pushed up, thereby releasing the restriction on the sliding piston rod 2081.

[0042] During the rotation of the rotary conveyor rack 109, the rotating lever 1081 rotates within the fixed disk 108 accordingly. At this time, the lifting baffle 209 blocks outside the sliding piston rod 2081, and the compression spring 2085 between the sliding block 2083 and the portal rod 2086 is compressed. At this time, the moving friction block 202 is not in contact with the feeding gear 204. The rotating gear 2 drives the spline shaft 201 and the moving friction block 202 to rotate. When the rotating lever 1081 contacts the lifting baffle 209 and pushes it to slide upward along the moving feeding plate 207, the lifting baffle 209 no longer blocks the sliding piston rod 2081. At this time, under the push of the compression spring 2085, the sliding block 2083 will push the lifting piston rod 2082 to slide into the liquid storage tube 208, and the sliding piston rod 2081 will be pushed outward by the hydraulic oil in the liquid storage tube 208. At this time, the sliding piston rod 2081 is inserted into the through hole in the middle of the lifting baffle 209. After the rotating lever 1081 disengages from the lifting baffle 209, the lifting baffle 209 will hang on the sliding piston rod 2081. When the sliding block 2083 descends, the lifting lever 2084 descends accordingly. At this time, the lifting lever 2084 just moves to the inside of the wedge-shaped protrusion 105. As the transmission shaft 101 continues to rotate, the lifting lever 2084 pulls the transmission gear 104 along the transmission shaft 101 to slide away from the driving gear 102 and compresses the expansion spring 106 through the wedge-shaped protrusion 105. When the rotating block 103 between the driving gear 102 and the transmission gear 104 disengages, the transmission gear 104 stops rotating, and the conveying gear 107, the rotating lever 1081, and the rotary conveyor rack 109 stop rotating accordingly. When the lifting lever 2084 pulls the transmission gear 104 to move through the wedge-shaped protrusion 105, the connecting frame 203 and the moving friction block 202 move along the spline shaft 201 accordingly. When the rotating block 103 between the driving gear 102 and the transmission gear 104 disengages, the moving friction block 202 just presses on the feeding gear 204. At this time, the driving gear 102 can drive the spline shaft 201, the moving friction block 202, and the feeding gear 204 to rotate through the rotating gear 2, and the reciprocating lead screw 206 rotates accordingly. At this time, the moving feeding plate 207 and the lifting baffle 209 inside it can slide along the feeding guide frame 205. When the lifting baffle 209 disengages from the sliding piston rod 2081, the lifting baffle 209 will slide downward along the moving feeding plate 207 to reset, and at the same time, push the cable at the highest position of the rotary conveyor rack 109 towards the outlet on the housing 1. During the process of the cable being pushed out of the housing 1, the lifting cutter 507 will horizontally cut the cable outer skin from the top. When the moving feeding plate 207 moves to the other end of the reciprocating lead screw 206, as the reciprocating lead screw 206 continues to rotate, the moving feeding plate 207 will slide along the feeding guide frame 205 to reset. During this process, the lifting baffle 209 will contact the sliding piston rod 2081 and push it to slide into the liquid storage tube 208. Under the action of the hydraulic oil in the liquid storage tube 208, the lifting piston rod 2082 will be pushed upward.The sliding block 2083 slides upward along the fixed disk 108 accordingly. After the lifting lever 2084 disengages from the wedge-shaped convex block 105, the driving gear 104 is pushed by the expanding spring 106 and slides along the transmission shaft 101 in the direction close to the driving gear 102. The connecting frame 203 and the moving friction block 202 slide along the spline shaft 201 accordingly, and the moving friction block 202 disengages from the pushing gear 204. At this time, the moving pushing plate 207 has moved and reset along the pushing guide frame 205. After the expanding spring 106 returns to its original state, the rotating catch 103 between the driving gear 104 and the driving gear 102 is engaged again. At this time, the driving gear 102 drives the driving gear 104 to rotate again through the rotating catch 103, and then drives the conveying gear 107 and the rotating conveying frame 109 to rotate and convey the cable.

[0043] As Figure 9 、 Figure 10 and Figures 13 - 15 shown, the adjusting mechanism includes a sliding adjustment frame 5, an adjusting spring 501, a swing rod 502, a lifting push rod 503, an L-shaped limiting frame 504, a fixed connection block 505, a rotating adjustment rod 506, a connecting slide rod 508 and a locking mechanism. The sliding adjustment frame 5 is slidably connected to the arc-shaped inner shell 1001. An adjusting spring 501 is provided between the sliding adjustment frame 5 and the housing 1. One end of the adjusting spring 501 is fixed to the sliding adjustment frame 5, and the other end is fixed to the housing 1. The lifting push rod 503 is slidably connected to the outside of the housing 1. The top surface of the lifting push rod 503 is an inclined surface. The swing rod 502 is rotatably connected to the outside of the housing 1. One end of the swing rod 502 is rotatably connected to the sliding adjustment frame 5, and the other end of the swing rod 502 is rotatably connected to the lifting push rod 503. One-word holes are provided at both ends of the swing rod 502. The L-shaped limiting frame 504 is slidably connected to the outside of the housing 1. The L-shaped limiting frame 504 matches the top inclined surface of the lifting push rod 503. A fixed connection block 505 is fixedly connected to the top of the L-shaped limiting frame 504. The rotating adjustment rod 506 is rotatably connected to the fixed connection block 505. The connecting slide rod 508 is slidably connected to the housing 1. One end of the connecting slide rod 508 is fixedly connected to the cutter, and the other end of the connecting slide rod 508 is rotatably connected to the rotating adjustment rod 506.

[0044] When the rotating conveying frame 109 rotates to push the cable, the cable will be pressed into the arc inner shell 1001 by the compression spring 111 and the arc pressure plate 110. When the cable passes through the sliding adjustment frame 5, the sliding adjustment frame 5 will be pushed by the cable and slide along the arc inner shell 1001. The adjustment spring 501 is compressed. At this time, the sliding adjustment frame 5 pushes the lifting push rod 503 to rise through the swing rod 502. When the lifting push rod 503 rises, it pushes the two L-shaped limit frames 504 away from each other, and the fixed connection block 505 moves accordingly. When the two fixed connection blocks 505 move away from each other, the rotating adjustment rod 50 6, the connecting slide bar 508 will slide downward along the shell 1 and drive the lifting cutter 507 to slide downward to adjust the cutting depth according to the cable diameter. Since the recycled waste cables are usually recycled and stored according to specifications, the cables of the same specification are processed within a certain period of time, and only one adjustment of the sliding adjustment frame 5 is required. When the cables pass through the sliding adjustment frame 5, the locking mechanism will limit the position of the sliding adjustment frame 5. After the same batch of cables is recycled, the equipment is turned off, and the locking mechanism can automatically release the restriction on the sliding adjustment frame 5.

[0045] like Figures 13 - 15As shown, the locking mechanism is used to limit the position of the sliding adjustment frame 5, and the locking mechanism includes a sliding limit rod 5001, a locking gear 6, a rotating open rod 601, a reset spring 602, a lifting locking rod 603, a support spring 604, a swing push rod 605, a sliding locking rod 606, a guide frame 607, a lifting locking frame 608, a wedge-shaped locking block 609, a locking spring 610 and a support spring 611. The sliding limit rod 5001 is fixedly connected to one end of the sliding adjustment frame 5 away from the swing rod 502, and the housing A locking gear 6 is rotatably connected in the body 1, and a rotating expansion rod 601 is slidably connected to the locking gear 6. A return spring 602 is provided between the rotating expansion rod 601 and the locking gear 6. One end of the return spring 602 is fixed to the locking gear 6, and the other end is fixed to the rotating expansion rod 601. A lifting locking rod 603 is slidably connected to the fixed plate 108. A supporting spring 604 is provided between the lifting locking rod 603 and the fixed plate 108. One end of the supporting spring 604 is fixed to the lifting locking rod 603, and the other end is fixed to the lifting locking rod 603. One end is fixed on the fixed disk 108, and a swing push rod 605 is rotatably connected to the fixed disk 108. The end of the swing push rod 605 away from the locking gear 6 is provided with a slotted hole. A sliding locking rod 606 is slidably connected in the shell 1. One end of the sliding locking rod 606 is slidably connected in the slotted hole on the swing push rod 605. A guide frame 607 is fixed in the shell 1. The guide frame 607 passes through the sliding limit rod 5001. A lifting locking frame 608 is slidably connected in the guide frame 607. The lifting locking frame 608 is connected to the locking gear 6. A supporting spring 611 is provided between the guide frames 607, one end of the supporting spring 611 is fixed to the lifting and clamping frame 608, and the other end is fixed to the guide frame 607. A wedge-shaped clamping block 609 is slidably connected to the lifting and clamping frame 608, and the side of the wedge-shaped clamping block 609 facing the clamping gear 6 is an inclined surface. A supporting spring 611 is provided between the wedge-shaped clamping block 609 and the lifting and clamping frame 608, one end of the supporting spring 611 is fixed to the wedge-shaped clamping block 609, and the other end is fixed to the lifting and clamping frame 608.

[0046] When the driving gear 102 rotates, it drives the clamping gear 6 to rotate. When the clamping gear 6 rotates, under the action of centrifugal force, the rotating expanding rod 601 slides along the clamping gear 6 and compresses the return spring 602. When the rotating expanding rod 601 slides outwards, it pushes the lifting clamping rod 603 to slide downwards along the fixed disk 108 and compresses the supporting spring 604. When the lifting clamping rod 603 descends, it pushes the swinging push rod 605 to rotate around the fixed disk 108. One end of the swinging push rod 605 away from the lifting clamping rod 603 will tilt upwards. During this process, the swinging push rod 605 pushes the sliding clamping rod 606 to slide into the guiding frame 607 along the housing 1. When the sliding clamping rod 606 slides into the guiding frame 607, it pushes the lifting clamping frame 608 to slide downwards and compresses the supporting spring 611. The wedge-shaped clamping block 609 on the lifting clamping frame 608 extends downwards through the guiding frame 607. When the sliding adjustment frame 5 is pushed by the cable and slides along the arc-shaped inner housing 1001, the sliding limit rod 5001 moves along the guiding frame 607 accordingly. During the movement of the sliding limit rod 5001, it contacts the inclined surface of the wedge-shaped clamping block 609. The wedge-shaped clamping block 609 is pushed by the sliding limit rod 5001 and slides upwards along the lifting clamping frame 608 and compresses the clamping spring 610. When the wedge-shaped clamping block 609 disengages from the sliding limit rod 5001, under the push of the clamping spring 610, the wedge-shaped clamping block 609 slides downwards along the guiding frame 607. At this time, the vertical surface on the wedge-shaped clamping block 609 will be stuck on the side of the sliding limit rod 5001 close to the driving gear 102. And according to the different diameters of the cables to be processed, the sliding distance of the sliding limit rod 5001 along the guiding frame 607 is different. No matter how far the sliding limit rod 5001 moves, there will always be a wedge-shaped clamping block 609 stuck on the side of the sliding limit rod 5001 close to the driving gear 102 to limit the sliding adjustment frame 5 through the sliding limit rod 5001. When the cables of the same specification are processed, the device is turned off. At this time, the clamping gear 6 stops rotating. Under the push of the return spring 602, the rotating expanding rod 601 slides back along the clamping gear 6. Under the push of the supporting spring 604, the lifting clamping rod 603 slides upwards to reset. The swinging push rod 605 is driven to rotate and reset. The sliding clamping rod 606 is pulled out of the guiding frame 607 by the swinging push rod 605. Under the push of the supporting spring 611, the lifting clamping frame 608 slides upwards to reset. The wedge-shaped clamping block 609 slides back into the guiding frame 607 and disengages from the sliding limit rod 5001 to release the restriction on the sliding adjustment frame 5, and components such as the lifting cutter 507 move synchronously to reset.

[0047] Embodiment 3: On the basis of Embodiment 2, as Figure 8 、 Figure 11 and Figure 12As shown, it further includes a circumferential cutting mechanism for circumferentially cutting the cable outer sheath. The circumferential cutting mechanism includes a circumferential cutting driving wheel 3, a circumferential cutting rotating shaft 301, a circumferential cutting driven wheel 302, a fixed frame 303, a circumferential cutting gear 304, a circumferential cutting knife 305 and a cutting-in component. The circumferential cutting rotating shaft 301 is rotatably connected inside the housing 1. One end of the circumferential cutting rotating shaft 301 is fixedly connected with the circumferential cutting driving wheel 3. The circumferential cutting driving wheel 3 meshes with the feeding gear 204. The other end of the circumferential cutting rotating shaft 301 is fixedly connected with the circumferential cutting driven wheel 302. The fixed frame 303 is fixedly connected outside the housing 1. The circumferential cutting gear 304 is rotatably connected inside the fixed frame 303. The circumferential cutting gear 304 meshes with the circumferential cutting driven wheel 302. The circumferential cutting knife 305 is slidably connected outside the circumferential cutting gear 304. The circumferential cutting knife 305 forms a certain angle with the housing 1 so that the circumferential cutting knife 305 can obliquely cut into the cable outer sheath. The circumferential cutting knife 305 rotates with the circumferential cutting gear 304. The cutting-in component is installed outside the circumferential cutting gear 304 and is used to make the circumferential cutting knife 305 cut into the cable outer sheath.

[0048] As Figure 11 and Figure 12 As shown, the cutting-in component includes an obliquely cutting-in tool head 3051 and a pushing spring 3052. A pushing spring 3052 is arranged between the circumferential cutting knife 305 and the circumferential cutting gear 304. One end of the pushing spring 3052 is fixed on the circumferential cutting knife 305, and the other end of the pushing spring 3052 is fixed on the circumferential cutting gear 304. An obliquely cutting-in tool head 3051 is fixedly connected to one end of the circumferential cutting knife 305 close to the housing 1.

[0049] After the moving pushing plate 207 pushes the cable out of the housing 1, the cable will slide out along the fixed frame 303. Driven by the feeding gear 204, the circumferential cutting driving wheel 3 drives the circumferential cutting driven wheel 302 to rotate through the circumferential cutting rotating shaft 301. The circumferential cutting driven wheel 302 drives the circumferential cutting gear 304 and the circumferential cutting knife 305 to rotate. The circumferential cutting knife 305 forms a certain angle with the outlet of the fixed frame 303. When the cable passes through the outlet of the fixed frame 303, the obliquely cutting-in tool head 3051 on the circumferential cutting knife 305 will obliquely cut into the cable outer sheath. And under the action of the pushing spring 3052, the circumferential cutting knife 305 and the obliquely cutting-in tool head 3051 will contact the inner core of the cable to completely cut off the cable outer sheath. During the process of the cable sliding out of the outlet of the fixed frame 303, the circumferential cutting knife 305 continuously rotates with the circumferential cutting gear 304 to circumferentially cut the cable outer sheath. The circumferential cutting knife 305 cooperates with the lifting cutting knife 507 to cut the cable outer sheath into multiple segments for easy recycling.

[0050] As Figure 6 , Figure 8 and Figure 9As shown, it further includes a limiting mechanism for preventing the outer cable sheath cut transversely from spreading to both sides. The limiting mechanism includes a connecting rod 2071, a wedge-shaped moving block 2072, a sliding limiting rod 4, a wedge-shaped fixed block 401, a limiting spring 402, an arc-shaped limiting plate 403 and a limiting block 404. A connecting rod 2071 is fixedly connected to the moving pusher plate 207, and a wedge-shaped moving block 2072 is fixedly connected to the connecting rod 2071. A sliding limiting rod 4 is slidably connected in the housing 1, and a wedge-shaped fixed block 401 is fixedly connected to the sliding limiting rod 4. The wedge-shaped moving block 2072 is matched with the wedge-shaped fixed block 401. A limiting spring 402 is arranged between the sliding limiting rod 4 and the housing 1. One end of the limiting spring 402 is fixed on the housing 1, and the other end is fixed on the sliding limiting rod 4. An arc-shaped limiting plate 403 is fixedly connected to the sliding limiting rod 4. The two arc-shaped limiting plates 403 are used for gathering and limiting the outer sheath of the cable cut transversely. A limiting block 404 is fixedly connected to the sliding limiting rod 4.

[0051] When the moving pusher plate 207 moves along the reciprocating lead screw 206 and withdraws the cable from the housing 1, the connecting rod 2071 moves accordingly. When the wedge-shaped moving block 2072 is disengaged from the wedge-shaped fixed block 401, under the push of the limiting spring 402, the two sliding limiting rods 4 and the components thereon slide along the housing 1 and approach each other. When the two arc-shaped limiting plates 403 approach each other, they will limit the outer sheath of the cable from both sides of the cable, preventing the outer sheath of the cable from opening to both sides. During the movement of the sliding limiting rod 4, the limiting block 404 at its bottom will contact the L-shaped limiting frame 504. The position of the L-shaped limiting frame 504 is related to the diameter of the cable. Under the action of the L-shaped limiting frame 504 and the limiting block 404, the distance between the two arc-shaped limiting plates 403 is also related to the diameter of the cable. The distance between the two arc-shaped limiting plates 403 will be automatically adjusted accordingly according to the diameter of the cable, so as to prevent the arc-shaped limiting plates 403 from clamping the outer skin of the cable too tightly and affecting the outward pushing speed.

[0052] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
