Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically to a cable outer sheath stripping device. Background Technology

[0002] Cables are typically encased in an oil-insulated outer sheath. During cable production, issues such as uneven sheath finish, inconsistent wire diameter, and substandard color transitions can lead to the recycling of substandard cables. Cables also require recycling after use and when they are deemed unsuitable. During cable recycling, the cable core is usually stripped for reuse to avoid waste. Currently, cable stripping is mostly done manually, using a blade to cut along the length of the cable and then manually separating the inner core from the insulation sheath. This method is inefficient and unsafe.

[0003] Chinese patent application CN202221169323.X discloses a cable material stripping and recycling device. This device involves a cable moving within a cylinder, where multiple cutting blades cut the cable's outer sheath. The cut cable enters a stripping block, where the stripping block separates the cable's outer sheath using an arc-shaped cutter, thus separating the cable core from the outer sheath. However, this method has a fixed cutting blade position and depth. When the cable enters the cylinder, gravity pulls it closer to the lower side of the cylinder. The cutting blades on the upper side are too far from the cable to completely cut the outer sheath, while the cutting blades on the lower side may damage the cable core, making it difficult to guarantee effective stripping. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable outer sheath stripping device. Multiple arc-shaped positioning blocks can limit the cable to the center of the cylinder, and the cutting blade can be adjusted radially relative to the cylinder to flexibly adjust the cutting depth. This can not only adapt to the stripping of cables of different thicknesses, but also avoid the situation where the cutting position shifts due to the cable moving inside the cylinder, thus ensuring the stripping effect of the cable.

[0005] This utility model provides a cable outer sheath stripping device to solve the above-mentioned technical problems. It includes a base, on which a cylindrical body is mounted. At least three sets of first radial holes are evenly distributed circumferentially on both sides of the cylindrical body. Movable blocks are slidably mounted within the first radial holes. The inner end of each movable block is fixed to an arc-shaped positioning block, and its outer end has a first wedge-shaped surface. A locking sleeve is threadedly connected to the outer side of the cylindrical body. One side of the locking sleeve has a second wedge-shaped surface that mates with the first wedge-shaped surface. At least two sets of second radial holes are provided in the middle of the cylindrical body. A screw is threadedly mounted within each of the second radial holes. The outer end of the screw has a turntable, and its inner end is rotatably connected to a mounting base. A cutting blade and a guide rod are mounted on the mounting base. The guide rod slidably engages with a guide hole on the cylindrical body. A separation disc located on one side of the cylindrical body is also provided on the base. The separation disc has a guide hole, and a separation gear with opposite rotation direction is provided on the side of the separation disc closest to the cylindrical body. The separation gear is driven to rotate by a driving mechanism.

[0006] Furthermore, the drive mechanism includes two meshing drive gears rotatably mounted on the base, one of which is fixed to the output end of the rotary motor, and the two drive gears are respectively meshed with transmission gears. The transmission gears are provided with transmission shafts, and the upper end of the transmission shafts is fixed to the separation gear.

[0007] Furthermore, the second radial hole is provided in two sets and is located on the upper and lower sides of the cylinder, and the two separation gears are located on the horizontal sides of the separation disc.

[0008] Furthermore, the inner wall of the cylinder is provided with radial grooves evenly distributed around the first radial hole, and an elastic element is provided in the radial groove, the other end of which is fixed to the arc-shaped positioning block.

[0009] Furthermore, the inner wall of the cylinder is provided with a receiving groove for accommodating the arc-shaped positioning block.

[0010] Furthermore, the inner side of the arc-shaped positioning block is provided with several ball bearings.

[0011] Furthermore, the guide rod is provided with a scale.

[0012] Furthermore, the cylinder is also provided with an inspection port.

[0013] The beneficial effects of this utility model are as follows: The base supports the cylinder and the separation disc. At least three sets of first radial holes are evenly arranged circumferentially on both sides of the cylinder. Movable blocks slide within these first radial holes. Through the engagement of the first wedge-shaped surface on the movable block and the second wedge-shaped surface on the locking sleeve, the movable block can move equidistantly towards the axis of the cylinder, thereby causing the arc-shaped positioning block to abut against the outer wall of the cable inside the cylinder, restricting the cable's position. At this time, both ends of the cable inside the cylinder are restricted to the center of the cylinder by the arc-shaped positioning block, preventing the cable from shifting within the cylinder under gravity. Furthermore, since the arc-shaped positioning block can move radially, it can limit the movement of cables of different diameters, offering strong adaptability. The second radial hole in the middle of the cylinder engages with the screw thread. The guide rod on the mounting base slides with the guide sliding hole on the cylinder to prevent the mounting base from rotating. By rotating the turntable, the screw rotates, causing the mounting base to move radially towards the cylinder, thereby adjusting the cutting depth of the cutting blade on the mounting base. This also allows for the cutting of outer sheaths of cables of different diameters and thicknesses. The cable core is guided by the guide holes on the separation disc. After the cable passes through the cylinder and its outer sheath is cut by the cutting blade, the outer sheath still wraps around the cable core. When one end of the cut cable moves out of the cylinder, the cable core is guided again through the guide holes. The separation gear, located in front of the guide holes, separates the cut outer sheath from the cable core, thus separating the cable core from the outer sheath. This invention uses multiple arc-shaped positioning blocks to confine the cable at the center of the cylinder. The cutting blade is adjustable radially relative to the cylinder, allowing for flexible adjustment of the cutting depth. This accommodates cables of different thicknesses and diameters and prevents the cutting position from shifting during cable movement within the cylinder, ensuring effective cable stripping.

Detailed Implementation

[0019] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0020] Reference Figures 1 to 3 This utility model provides a cable outer sheath stripping device, including a base 1, which supports the cylinder 2 and the separation disc 5. Of course, a cable unwinding mechanism can be installed on one side of the base 1, and a cable core winding mechanism can be installed on the other side near the separation disc 5. The unwinding and winding mechanisms can use existing devices. This embodiment illustrates that both the unwinding and winding mechanisms can use motors, rollers, mounting frames, etc. The roller is mounted on the mounting frame, and the motor drives the roller to rotate, unwinding or winding the cable spool mounted on the roller.

[0021] The base 1 is provided with a cylindrical body 2. The front and rear sides of the cylindrical body 2 have flared guide openings to facilitate the insertion of cables into the cylindrical body 2. At least three sets of first radial holes 21 are evenly distributed circumferentially on both sides of the cylindrical body 2. Movable blocks 22 are slidably disposed within the first radial holes 21. The inner end of the movable block 22 is fixed to an arc-shaped positioning block 23, and the outer end has a first wedge-shaped surface 221. The inner side of the arc-shaped positioning block 23 has several ball bearings 231. When the cable is inserted into the cylindrical body 2 and confined by the arc-shaped positioning block 23, the ball bearings 231 on the arc-shaped positioning block 23 roll in contact with the outer wall of the cable, facilitating axial movement of the cable within the cylindrical body 2. Furthermore, when the outer sheath of the cable is cut, the rolling of the ball bearings 231 compresses the outer sheath, loosening the connection between the outer sheath and the cable core, facilitating subsequent stripping. A locking sleeve 3 is threadedly connected to the outer side of the cylindrical body 2. One side of the locking sleeve 3 has a second wedge-shaped surface 31 that mates with the first wedge-shaped surface 221. At this time, rotating the locking sleeve 3 causes the side of the locking sleeve 3 with the second wedge-shaped surface 31 to move towards the movable block 22. The movable block 22 is confined within the first radial hole 21. The second wedge-shaped surface 31 engages with the first wedge-shaped surface 221 on the movable block 22, squeezing the movable block 22 and causing it to move towards the axis of the cylinder 2. Since the first radial hole 21 is arranged circumferentially along the cylinder 2, the locking sleeve 3 can cause multiple sets of movable blocks 22 to move equidistantly towards the axis of the cylinder 2. This allows multiple arc-shaped positioning blocks 23 to move equidistantly towards the axis of the cylinder 2, thereby abutting against the outer wall of the cable inside the cylinder 2. This restricts the position of the cable at both ends inside the cylinder 2, ensuring it remains at the center of the cylinder 2. This prevents the cable from shifting under gravity, which could cause uneven cutting or slippage by the cutting blade 43. Furthermore, since the arc-shaped positioning blocks 23 can move radially, they can be used to limit cables of different diameters, offering strong adaptability. Furthermore, the inner wall of the cylinder 2 is provided with radial grooves 261 evenly distributed around the first radial hole 21. An elastic element 262 is provided within the radial grooves 261, and the other end of the elastic element 262 is fixed to the arc-shaped positioning block 23. In this case, the elastic element 262 can both confine the arc-shaped positioning block 23 within the first radial hole 21, preventing it from detaching from the first radial hole 21, and can also pull the arc-shaped positioning block 23 so that it always has a tendency to move outwards from the cylinder 2, allowing the arc-shaped positioning block 23 to fit against the inner wall of the cylinder 2, reducing the possibility of interference between the cable and the arc-shaped positioning block 23 when the cable enters the cylinder 2. Furthermore, the inner wall of the cylinder is provided with a receiving groove 26 for accommodating the arc-shaped positioning block 23. Under the pull of the elastic element 262, the arc-shaped positioning block 23 can be positioned within the receiving groove 26 without protruding from the inner wall of the cylinder 2, further preventing interference between the cable and the arc-shaped positioning block 23 when the cable enters the cylinder 2.

[0022] The cylinder 2 has at least two sets of second radial holes 24 in its middle section. A screw 4 is threaded into each of the second radial holes 24. The outer end of the screw 4 has a turntable 41, and the inner end is rotatably connected to a mounting base 42. A cutting blade 43 is mounted on the mounting base 42. Preferably, the mounting base 42 and the cutting blade 43 are detachably fixed for easy replacement of the cutting blade 43. Furthermore, the cylinder 2 also has an inspection port 27 for easy replacement of the cutting blade 43. A guide rod 44 is mounted on the mounting base 42, and the guide rod 44 slides with a guide hole 25 on the cylinder 2 to prevent rotation of the mounting base 42. Furthermore, the guide rod 44 has graduations for easy observation of the cutting depth of the cutting blade 43. Rotating the turntable 41 drives the screw 4 to rotate. The screw 4 engages with the second radial hole 24, causing the mounting base 42 to move radially toward the cylinder 2. This allows for adjustment of the cutting depth of the cutting blade 43 on the mounting base 42, and also adapts to the cutting of outer sheaths of cables with different diameters and thicknesses.

[0023] The base 1 is also provided with a separation disc 5 located on one side of the cylinder 2. The separation disc 5 is provided with a guide hole 51. The side of the separation disc 5 near the cylinder 2 is also provided with a separation gear 6 with opposite rotation direction. The separation gear 6 is driven to rotate by a drive mechanism 7. The guide hole 51 on the separation disc 5 guides the cable core. When the cable passes inside the cylinder 2, after the outer sheath is cut by the cutting blade 43, the outer sheath of the cable still wraps around the cable core and moves with it. After one end of the cut cable moves out of the cylinder 2, it guides the cable core through the guide hole 51. The separation gear 6 separates the cut outer sheath on the cable core on the front side of the guide hole 51, causing it to detach from the cable core, thus completing the separation of the cable core and the outer sheath. Furthermore, the second radial hole 24 is provided in two sets and located on the upper and lower sides of the cylinder 2. The two separating gears 6 are located on the horizontal sides of the separating disc 5. In this way, the upper and lower sets of cutting blades 43 cut open the upper and lower sides of the outer sheath of the cable, and the outer sheath of the cable is cut into two halves. When it moves to the arc-shaped positioning block 23 at the cable outlet, it is rolled and squeezed by the ball 231 on the arc-shaped positioning block 23, so that the outer sheath and the cable core are loosened. Then, when it moves to the separating disc 5, the two separating gears 6 rotate, and the two halves of the outer sheath are peeled off to both sides through the separating gears 6.

[0024] Furthermore, the drive mechanism 7 includes two meshing drive gears 71 rotatably mounted on the base 1. One drive gear 71 is fixed to the output end of the rotary motor 74, and each of the two drive gears 71 meshes with a transmission gear 72. The transmission gear 72 is provided with a transmission shaft 73, and the upper end of the transmission shaft 73 is fixed to the separating gear 6. At this time, the rotary motor 74 drives one of the drive gears 71 to rotate, which in turn drives the other drive gear 71 to rotate in the opposite direction. The two drive gears 71 then drive their adjacent transmission gears 72 to rotate in the opposite direction, which in turn drives the separating gear 6 to rotate in the opposite direction, thus peeling off the outer sheath.

[0025] In use, the cable is threaded into the cylinder 2. Then, the locking sleeves 3 on both sides of the cylinder 2 are rotated, causing multiple movable blocks 22 to move equidistantly towards the axis of the cylinder 2. This causes multiple arc-shaped positioning blocks 23 to press against the outer wall of the cable. At this time, the balls 231 on the arc-shaped positioning blocks 23 roll in contact with the outer wall of the cable, facilitating axial movement of the cable within the cylinder 2. Then, depending on the size of the cable and the thickness of the outer sheath, the screw 4 is rotated via the rotating disc, driving the cutting blade 43 on the mounting base 42 to move towards the axis of the cylinder 2, adjusting the cutting depth of the cutting blade 43. After the cable with the outer sheath cut out passes through the cylinder 2, the cable core passes through the guide hole 51 on the separating disc 5. During the cable movement, the drive mechanism 7 drives the separating gear 6 to rotate in the opposite direction, peeling off the cut outer sheath from the cable core.
