[0002] Cable is a general term for optical cables, electrical cables, etc. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity, and other multiple functions. They are common and indispensable items in daily life.

[0003] When cables cannot be used normally, in order to achieve resource recycling, they are usually stripped and the internal copper wires are then recycled. However, when existing stripping equipment processes waste cables, cables of different diameters require stripping cutters of different specifications. A single device is difficult to meet the needs of processing cables of different diameters.

[0004] The patent with patent number CN220492560U discloses a stripping device for recycling waste cables, including a fixed base, a lifting assembly is arranged on one side of the top of the fixed base, the lifting assembly includes a telescopic rod fixed at both ends of the top of the fixed base, a supporting roller is installed on the top of the telescopic rod, and limiting groove plates are arranged at both ends of the top of the supporting roller, a conveying assembly is arranged in the middle of the fixed base, and the conveying assembly includes a supporting frame installed at both ends of the top of the fixed base, and a cutting assembly is arranged at the other end of the top of the fixed base; the lifting assembly arranged in the invention can ensure that the ends of the cables are smoothly conveyed during stripping to avoid the ends from curling up, and the limiting groove plates arranged on both sides can limit and block the two sides of the cables to avoid falling, thereby reducing the physical strength consumed in lifting and avoiding deviation to a certain extent, and adjusting the spacing of the stripping blades on both sides by using the spacing-adjustable cutting assembly, so that the device can cut cables of different diameters.

[0005] When the above-mentioned device recycles and processes cables, it is necessary to manually adjust the distance between the extrusion tooth rollers by adjusting the screw to extrude and transport the cables, and then adjust the distance between the stripping blades by a bidirectional screw to strip cables of different diameters. However, all adjustment processes need to be performed manually, and the adjustment results may be inaccurate, which may result in the cable sheath not being completely cut off, affecting the recycling efficiency.

[0016] The beneficial effects are as follows: 1. The device is divided into two parts, one for conveying cables upward and the other for pushing cables outward. The part for conveying cables upward can push cables upward through the rotating conveying frame and the arc-shaped pressure plate, and every time the rotating conveying frame rotates 60 degrees, the lifting lever will drop and separate the transmission gear from the active gear through the wedge-shaped protrusion. When the rotating block between the transmission gear and the active gear is out of contact, the rotating conveying frame stops rotating, and at this time the pushing gear contacts the moving friction block, and the mechanism for pushing the cables outward operates, the pushing gear is driven to rotate, and the reciprocating screw rotates accordingly and pushes the cables to move through the moving pushing plate. In this process, the lifting cutter cuts the cable sheath horizontally, and the moving pushing plate moves and resets the transmission gear again, and the rotating conveying frame rotates again and conveys the cables upward, and the structure for conveying cables upward and the structure for pushing cables outward replace each other to quickly and automatically cut the cable sheath.

[0017] 2. When processing the same batch of cables, 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 the lifting cutter will be driven up and down through the swing rod, lifting push rod and other components 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 will also be locked. After the same batch of cables are processed, the equipment is turned off. At this time, the locking mechanism will automatically release the restriction on the sliding adjustment frame, and the sliding adjustment frame will automatically move and reset, and the lifting cutter and other components will move and reset accordingly. The next time the cable is processed, the height of the lifting cutter will be 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 outward, two arc-shaped limiting plates limit the cable from both sides to prevent the cable sheath from spreading to both sides. When the cable passes through the fixed frame, the circular cutting knife rotating with the circular cutting gear will cut the cable sheath in a circular manner. The cut sheath automatically breaks away from contact with the wire core and falls downward. When the oblique cutting knife on the circular cutting knife contacts the cable sheath, the oblique cutting knife and the circular cutting knife are in oblique contact with the cable sheath, so that the oblique cutting knife and the circular cutting knife can cut into the cable 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 Figure 1-Figure 15As shown, it includes a shell 1, an arcuate inner shell 1001, a transmission shaft 101, a driving gear 102, a rotating block 103, a transmission gear 104, a conveying gear 107, a fixed disk 108, a rotating conveying frame 109, a clamping assembly, a conveying and cutting mechanism and an adjusting mechanism. The arcuate inner shell 1001 is fixedly connected in the shell 1, and there is a rectangular entrance between the shell 1 and the arcuate inner shell 1001. The cable is sent into the rotating conveying frame 109 in the shell 1 from the rectangular entrance. The fixed disks 108 are fixedly connected at both ends of the arcuate inner shell 1001. The arcuate inner shell 1001 and the fixed disk 108 form a cylindrical cabin. The shell 1 is rotatably connected with the transmission shaft 101, which passes through the shell 1 and is connected to the fixed disk 108. The driving gear 102 is fixedly connected to the transmission shaft 101, and the rotating block 103 is fixedly connected to the driving gear 102. The transmission shaft 101 is slidably connected with the transmission gear 104. A rotating block 103 is fixedly connected to the transmission gear 104, and the rotating block 103 between the transmission gear 104 and the driving gear 102 can be engaged with each other, and the driving gear 102 can drive the transmission gear 104 to rotate only after the two rotating blocks 103 are engaged. A conveying gear 107 is rotatably connected to the fixed disk 108, and the conveying gear 107 is always meshed with the transmission gear 104. A rotating conveying frame 109 is rotatably connected in the two fixed disks 108, and the rotating conveying frame 109 is coaxially fixed with the conveying gear 107. The clamping assembly is installed in the rotating conveying frame 109, and the rotating conveying frame 109 conveys the cable upward through the clamping assembly when the rotating conveying frame 109 rotates. The conveying and cutting mechanism is installed in the shell 1, and the conveying and cutting mechanism conveys the cable outward and cuts the cable sheath horizontally. The adjusting mechanism is installed on the shell 1 and the arc-shaped inner shell 1001, and the adjusting mechanism adjusts the height of the cutter in the conveying and cutting mechanism according to the cable diameter.

[0037] When processing waste cables, first push the cables from the entrance between the arc-shaped inner shell 1001 and the shell 1 to the rotating conveyor frame 109, and the clamping assembly presses the cables 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 clamping block 103 between the driving gear 102 and the transmission gear 104 is docked together. During the rotation process, the driving gear 102 drives the transmission gear 104 to rotate through the rotating clamping block 103. When the transmission gear 104 rotates, the rotating conveyor frame 109 is driven to rotate through the conveying gear 107. During the rotation of the rotating conveyor frame 109, the cables are driven to move upward inside the arc-shaped inner shell 1001 through the clamping assembly. After the rotating conveyor frame 109 rotates 60 degrees, a new cable is sent into the arc-shaped inner shell 1001 through the entrance. When the rotating conveyor frame 109 rotates 60 degrees, a new cable is sent into the arc-shaped inner shell 1001 through the entrance. When the delivery rack 109 delivers the cable to the highest point, the conveying and cutting assembly will drive the transmission gear 104 to slide along the transmission shaft 101, so that the rotating block 103 between the transmission gear 104 and the active gear 102 is out of contact. At this time, the transmission gear 104, the conveying gear 107 and the rotating conveying rack 109 stop rotating, and the conveying and cutting assembly runs and pushes the cable outward from the top outlet of the shell 1. In the process of the cable being pushed out, the insulating skin on the outside will be cut horizontally by the conveying and cutting assembly. When the conveying and cutting assembly moves and resets, the rotating block 103 between the active gear 102 and the transmission gear 104 is automatically engaged, and the rotating conveying rack 109 continues to rotate and conveys the cable upward. In the process of conveying the cable, the rotating conveying rack 109 will drive the adjustment mechanism to run according to the cable specifications, and then adjust the conveying and cutting mechanism through the adjustment mechanism.

[0038] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5 As shown, the clamping assembly includes a fixed rod 1091, an arc-shaped pressure plate 110 and a clamping spring 111. The fixed rod 1091 is fixedly connected inside the rotating conveying frame 109, and the arc-shaped pressure plate 110 is slidably connected to the fixed rod 1091. A clamping spring 111 is provided between the arc-shaped pressure plate 110 and the fixed rod 1091. One end of the clamping spring 111 is fixed on the fixed rod 1091, and the other end is fixed on the arc-shaped pressure plate 110. The clamping spring 111 clamps the cable through the arc-shaped pressure 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 rotating conveyor frame 109, and finally the cable is pushed between the arc-shaped pressure plate 110 on the rotating conveyor frame 109 and the arc-shaped inner shell 1001. At this time, under the action of the clamping spring 111, the arc-shaped pressure plate 110 is tightly attached to the cable, and the rotation of the rotating conveyor frame 109 will drive the cable to move along the inner arc surface of the arc-shaped inner shell 1001 through the arc-shaped pressure plate 110, so as to realize the function of conveying the cable.

[0040] like Figure 3 , Figure 4 , Figure 6-Figure 8 and Fig.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, the shifting 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 pressing spring 2085, a gate-shaped rod 2086 and a lifting baffle 209. The transmission gear 104 is fixedly connected with the wedge-shaped protrusion 105, which 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 in 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. The liquid storage tube 208 is horizontally slidably connected to a sliding piston rod. 2081, the sliding piston rod 2081 passes through the moving push plate 207 and is slidably connected thereto, the liquid storage tube 208 is slidably connected to the lifting piston rod 2082 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 plate 108, a lifting lever 2084 is fixedly connected to the sliding block 2083, a door-shaped rod 2086 is fixedly connected to the outside of the fixed plate 108, and the sliding block 2083 is slidably connected to the door-shaped rod 2086 Then, a downward pressure spring 2085 is provided between the door-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 door-shaped rod 2086. A lifting baffle 209 is slidably connected inside the movable push plate 207. The lifting baffle 209 is used to limit the sliding piston rod 2081. When the lever 1081 rotates, the lifting baffle 209 will be pushed up, thereby releasing the restriction on the sliding piston rod 2081.

[0042] During the rotation of the rotating conveyor frame 109, the rotating lever 1081 rotates accordingly in the fixed disk 108. At this time, the lifting baffle plate 209 is blocked outside the sliding piston rod 2081, and the downward pressure spring 2085 between the sliding block 2083 and the door-shaped rod 2086 is compressed. At this time, the moving friction block 202 is not in contact with the pushing gear 204, and 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 plate 209 and pushes it to slide upward along the moving pushing plate 207, the lifting baffle plate 209 no longer blocks the sliding piston rod 2081. At this time, under the push of the downward pressure 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 is out of contact with the lifting baffle 209, the lifting baffle 209 will be hung on the sliding piston rod 2081. When the sliding block 2083 descends, the lifting lever 2084 will also descend. 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 through the wedge-shaped protrusion 105 to slide along the transmission shaft 101 in the direction away from the driving gear 102 and compresses the expansion spring 106. When the rotating block 103 between the driving gear 102 and the transmission gear 104 is out of contact, the transmission The gear 104 stops rotating, and the conveying gear 107, the rotating lever 1081 and the rotating conveying frame 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 accordingly on the spline shaft 201. When the rotating block 103 between the driving gear 102 and the transmission gear 104 is out of contact, the moving friction block 202 just presses on the push gear 204. At this time, the driving gear 102 can drive the spline shaft 201, the moving friction block 202 and the push gear 204 to rotate through the rotating gear 2, and the reciprocating screw 206 rotates accordingly. At this time, the moving push plate 207 and the lifting baffle 209 inside it can slide along the push guide frame 205. When the lifting baffle 209 is out of contact with the sliding piston rod 2081, the lifting baffle 209 will slide downward along the moving push plate 207 to reset, and at the same time, the cable sent to the highest point of the rotating conveyor frame 109 will be pushed toward the outlet on the shell 1. In the process of the cable being pushed out of the shell 1, the lifting cutter 507 will cut the cable sheath horizontally from the top. When the moving push plate 207 moves to the other end of the reciprocating screw 206, as the reciprocating screw 206 continues to rotate, the moving push plate 207 will slide and reset along the push guide frame 205. In 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 then slides upward along the fixed plate 108. When the lifting lever 2084 is out of contact with the wedge-shaped protrusion 105, the transmission gear 104 is pushed by the expansion 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 then slide along the spline shaft 201. The moving friction block 202 is out of contact with the push gear 204. At this time, the moving push plate 207 has moved back along the push guide frame 205. When the expansion spring 106 is restored to its original state, the rotating block 103 between the transmission gear 104 and the driving gear 102 is clamped together again. At this time, the driving gear 102 drives the transmission gear 104 to rotate again through the rotating block 103, thereby driving the conveying gear 107 and the rotating conveying frame 109 to rotate and convey the cable.

[0043] like Fig. 9 , Fig.10 and Figure 13-Figure 15 As shown, the adjustment mechanism includes a sliding adjustment frame 5, an adjustment spring 501, a swing rod 502, a lifting push rod 503, an L-shaped limit frame 504, a fixed connection block 505, a rotation 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, and an adjustment spring 501 is provided between the sliding adjustment frame 5 and the shell 1. One end of the adjustment spring 501 is fixed to the sliding adjustment frame 5, and the other end is fixed to the shell 1. The lifting push rod 503 is slidably connected to the outside of the shell 1, and 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 shell 1. One end of the 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.

[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 Figure 13-Figure 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 will drive the locking gear 6 to rotate. When the locking gear 6 rotates, under the action of centrifugal force, the rotating propping rod 601 will slide along the locking gear 6 and compress the reset spring 602. When the rotating propping rod 601 slides outward, it will push the lifting locking rod 603 to slide downward along the fixed plate 108 and compress the supporting spring 604. When the lifting locking rod 603 descends, it will push the swing push rod 605 to rotate around the fixed plate 108. The end of the swing push rod 605 away from the lifting locking rod 603 will tilt upward. In this process, the swing push rod 605 will push the sliding locking rod 606 to slide along the shell 1 into the guide frame 607. When the positioning rod 606 slides into the guide frame 607, it pushes the lifting positioning frame 608 to slide downward and compresses the support spring 611. The wedge-shaped positioning block 609 on the lifting positioning frame 608 passes through the guide frame 607 and extends downward. When the sliding adjustment frame 5 is pushed by the cable and slides along the arc-shaped inner shell 1001, the sliding limit rod 5001 moves along the guide frame 607. During the movement of the sliding limit rod 5001, it will contact the inclined surface of the wedge-shaped positioning block 609. The wedge-shaped positioning block 609 will be pushed by the sliding limit rod 5001 and slide upward along the lifting positioning frame 608 and compress the positioning spring 610. When the wedge-shaped positioning block 609 and the sliding limit rod After 5001 is out of contact, the wedge-shaped blocking block 609 slides downward along the guide frame 607 under the push of the blocking spring 610. At this time, the vertical surface of the wedge-shaped blocking block 609 will be stuck on the side of the sliding limit rod 5001 close to the active gear 102. According to the different diameters of the cables to be processed, the sliding limit rod 5001 slides along the guide frame 607 at different distances. When the sliding limit rod 5001 moves at different distances, there will be a wedge-shaped blocking block 609 stuck on the side of the sliding limit rod 5001 close to the active gear 102, so as to limit the sliding adjustment frame 5 through the sliding limit rod 5001. When the cables of the same specification are processed, , turn off the equipment, at this time the locking gear 6 stops rotating, and under the push of the reset spring 602, the rotating propping rod 601 slides and resets along the locking gear 6, and under the push of the supporting spring 604, the lifting locking rod 603 slides upward and resets, and the swing push rod 605 is driven to rotate and reset, and the sliding locking rod 606 is pulled out of the guide frame 607 by the swing push rod 605, and under the push of the propping spring 611, the lifting locking frame 608 slides upward and resets, and the wedge-shaped locking block 609 slides into the guide frame 607 again and disengages from the sliding limit rod 5001 to release the restriction on the sliding adjustment frame 5, and the lifting cutter 507 and other components move synchronously and reset.

A push spring 3052 is provided between the circular cutting knife 305 and the circular cutting gear 304. One end of the push spring 3052 is fixed to the circular cutting knife 305, and the other end of the push spring 3052 is fixed to the circular cutting gear 304. The oblique cutting head 3051 is fixedly connected to one end of the circular cutting knife 305 close to the shell 1.

[0049] After the push plate 207 is moved to push the cable out of the housing 1, the cable will slide out along the fixed frame 303. Driven by the push gear 204, the ring cutting driving wheel 3 drives the ring cutting driven wheel 302 to rotate through the ring cutting shaft 301. The ring cutting driven wheel 302 drives the ring cutting gear 304 and the ring cutting knife 305 to rotate. The ring cutting knife 305 has a certain angle with the outlet of the fixed frame 303. When the cable passes through the outlet of the fixed frame 303, the oblique angle on the ring cutting knife 305 The cutting head 3051 will cut into the cable sheath at an angle, and under the action of the push spring 3052, the circular cutting knife 305 and the oblique cutting head 3051 will contact the internal core of the cable to completely cut off the cable sheath. In the process of the cable sliding out from the exit of the fixed frame 303, the circular cutting knife 305 rotates continuously with the circular cutting gear 304 to cut the cable sheath in an annular direction. The circular cutting knife 305 cooperates with the lifting cutter 507 to cut the cable sheath into multiple sections for easy recycling.

[0051] When the movable push plate 207 moves along the reciprocating screw rod 206 and withdraws the cable from the shell 1, the connecting rod 2071 moves accordingly. When the wedge-shaped moving block 2072 is out of contact with the wedge-shaped fixed block 401, under the push of the limiting spring 402, the two sliding limiting rods 4 and their upper parts slide along the shell 1 and move closer to each other. When the two arc limiting plates 403 move closer to each other, the cable sheath will be limited from both sides of the cable to prevent the cable sheath from opening to both sides. During the movement of the sliding limiting rod 4, the limiting block 404 at the bottom will contact the L-shaped limiting frame 504. The position of the L-shaped limiting frame 504 is related to the cable diameter. Under the action of the L-shaped limiting frame 504 and the limiting block 404, the distance between the two arc limiting plates 403 is also related to the cable diameter.
