Description

Technical Field

[0001] This invention relates to the field of cable production technology, specifically to a cable stripping and cutting device and a cable stripping processing box. Background Technology

[0002] Cable stripping is a fundamental procedure in cable installation, maintenance, and splicing. Its core function is to remove the outer insulation layer or sheath without damaging the conductor, shielding layer, or other internal structures. However, existing cable stripping devices cannot actively collect the cable sheath during the stripping process, hindering the recovery of the insulation and sheath.

[0003] To this end, Chinese Patent No. CN119626681B discloses a cable stripping device for cable production. The cable enters the second annular groove on the second stripping roller through the conductor roller. The second stripping roller drives the annular stripping knife to rotate. The annular stripping knife cuts the inner insulation layer covering the surface of the conductor, so that the inner insulation layer on the surface of the conductor is separated from the conductor. The inner insulation layer then contacts the conductor winding roller through the second conductor unit. During the rotation of the conductor winding roller, the conductor winding roller winds up the stripped conductor metal in the cable, thereby realizing the recovery of conductor metal and facilitating the production and manufacturing of the cable.

[0004] However, existing stripping devices use stripping blades on stripping rollers for cutting. If the stripping rollers do not rotate at a sufficient speed, intermittent stripping occurs, leaving some insulation layer stuck on the cable. Conversely, if the speed is too high, some inner insulation layer may be peeled off while cutting the outer insulation layer, leading to a mixture of different waste materials and affecting waste recycling.

[0015] A cable stripping processing box includes the aforementioned cable stripping and cutting device.

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention achieves continuous stripping through a frame and cutting mechanism, and can stably cut the insulation layer by controlling the cutting depth of the cutting blade. By connecting multiple cutting mechanisms in series, it is possible to sequentially cut multiple layers of insulation or sheath. The ring cutting method avoids some insulation layer remaining on the cable, solving the problem of mixed recycled materials caused by the stripping efficiency affecting the stripping process in traditional stripping devices. In operation, the operator first activates the traction component to pull the cable. Simultaneously, the rotary driver drives the first rotating gear to rotate, which in turn drives the gear ring to rotate via the second rotating gear. The gear ring drives the sleeve to rotate, and then the cutting blade on the sleeve cuts the insulation layer. At this time, the traction component continues to pull the cable, further cutting the insulation layer into spiral-shaped waste. With the continuous traction of the traction component, continuous stripping of the cable is completed.

[0018] 2. This invention achieves the function of cutting off the stripped insulation layer through an upper cutter, a lower cutter, and an auxiliary control mechanism. It periodically cuts off the stripped insulation layer, thereby automatically collecting the spiral-shaped insulation waste and avoiding the problem of the stripped insulation layer getting tangled on the cable and being unable to be collected smoothly.

[0019] 3. This invention achieves the function of controlling the lifting and lowering of the lower cutter through a first guide rod, a first elastic element, a limiting component, and a control component, thereby quickly cutting off the insulation waste when the cable stops moving. In the working state, the limiting component restricts the first guide rod from moving upwards under the elastic force of the first elastic element. At this time, the first elastic element is in a compressed state, and its elastic force acts on the first limiting block, causing the lower cutter and the first guide rod to have an upward tendency. When the cable stops moving forward, the control component releases the restriction on the movement of the first guide rod. Then, the first elastic element pushes the first limiting block upwards, and the first limiting block drives the first guide rod and the lower cutter upwards, completing the cutting off of the insulation waste through the cooperation of the lower and upper cutters.

Detailed Implementation

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1-4 The device includes a frame 1 and a cutting mechanism 2. The frame 1 is provided with a mounting base 11 and a traction component 12 for pulling the cable 5 inside the frame 1. The cutting mechanism 2 includes a rotary drive component 21 and a sleeve 22. The sleeve 22 is rotatably mounted on the mounting base 11 and the rotary drive component 21 is used to drive the sleeve 22 to rotate. The sleeve 22 is provided with a cutting blade 221 for cutting the insulation layer of the cable 5.

[0033] This invention achieves continuous stripping through the frame 1 and cutting mechanism 2, and can stably cut the insulation layer by controlling the cutting depth of the cutting blade 221. By connecting multiple cutting mechanisms 2 in series, it is possible to sequentially cut multiple layers of insulation or sheath. The ring cutting avoids some insulation layer remaining on the cable 5, solving the problem of mixed recycled materials caused by the stripping efficiency of traditional stripping devices. The frame 1 is located inside the processing box 6. The rotary drive assembly 21 includes a rotary driver 211, a first rotary gear 212, a second rotary gear 213, and a gear ring 214. The rotary driver 211 is mounted on the frame 1, the first rotary gear 212 is sleeved on the drive end of the rotary driver 211, the second rotary gear 213 is rotatably mounted on the frame 1, and the gear ring 214 is sleeved on the sleeve 22. The second rotary gear 213 meshes with both the first rotary gear 212 and the gear ring 214. In operation, the operator first activates the traction assembly 12 to pull the cable 5. Simultaneously, the rotary driver 211 drives the first rotary gear 212 to rotate. The first rotary gear 212 drives the gear ring 214 to rotate via the second rotary gear 213. The gear ring 214 drives the sleeve 22 to rotate, which in turn cuts the insulation layer through the cutting blade 221 on the sleeve 22. At this time, the traction assembly 12 is still pulling the cable 5, thereby cutting the insulation layer into spiral-shaped waste material. With the continuous pulling of the traction assembly 12, the continuous stripping of the cable 5 is completed.

[0034] Reference Figures 3-5 The frame 1 is equipped with a mounting plate 3 and an auxiliary control mechanism 4; the mounting plate 3 is equipped with an upper cutter 31 and a lower cutter 32, the upper cutter 31 is connected to the mounting plate 3, and the lower cutter 32 is located directly below the upper cutter 31; the auxiliary control mechanism 4 is used to control the lower cutter 32 to move up and down in the vertical direction.

[0035] This invention achieves the function of cutting off the stripped insulation layer through the upper cutter 31, the lower cutter 32, and the auxiliary control mechanism 4. It periodically cuts the stripped insulation layer, achieving the effect of automatically collecting the spiral-shaped insulation waste, thus avoiding the problem of the stripped insulation layer getting tangled on the cable 5 and unable to be collected smoothly. The stripping of the cable 5 is completed through the cooperation of the traction component 12 and the rotary drive component 21. During the stripping process, the traction component 12 is activated intermittently. When the traction component 12 stops pulling, the rotary drive component 21 continues to drive the sleeve 22 to rotate. After the cutting blade 221 rotates one revolution, the insulation layer is initially cut off. At this time, although the spiral-shaped insulation waste is separated from the cable 5, it is still tangled on the cable 5. Since the lower cutter 32 is close to the cable 5, and the insulation waste is in an expanded state after being separated from the cable 5, the lower cutter 32 will be inside the insulation waste. At this time, the lower cutter 32 is controlled to move upward by the auxiliary control mechanism 4. Then, the upper cutter 31 and the lower cutter 32 cooperate to complete the secondary cutting of the spiral insulation waste. The cut waste falls to the designated collection point under the action of gravity.

[0036] Reference Figures 3-5 A first guide rod 33 is connected to the lower cutter 32. The first guide rod 33 is slidably engaged with the mounting plate 3. A first limiting block 331 is provided at the end of the first guide rod 33 away from the lower cutter 32. A first elastic element 34 is sleeved on the first guide rod 33. The two ends of the first elastic element 34 are respectively connected to the first limiting block 331 and the mounting plate 3. The auxiliary control mechanism 4 includes a limiting component 41 and a control component 42. The limiting component 41 is used to limit the upward movement of the first guide rod 33. When the cable 5 stops moving, the control component 42 releases the movement restriction of the first guide rod 33 by the limiting component 41.

[0037] This invention utilizes a first guide rod 33, a first elastic element 34, a limiting component 41, and a control component 42 to control the lifting and lowering of the lower cutter 32, achieving the effect of quickly cutting off the insulation waste when the cable 5 stops moving. At least two first guide rods 33 are provided, and each first guide rod 33 is fixedly connected to the lower cutter 32. In the working state, the limiting component 41 restricts the first guide rod 33 from moving upward under the elastic force of the first elastic element 34. At this time, the first elastic element 34 is in a compressed state, and its elastic force acts on the first limiting block 331, causing the lower cutter 32 and the first guide rod 33 to have an upward tendency. When the cable 5 stops moving forward, the control component 42 releases the restriction on the movement of the first guide rod 33 from the limiting component 41. Then, the first elastic element 34 pushes the first limiting block 331 upward, and the first limiting block 331 drives the first guide rod 33 and the lower cutter 32 upward, completing the cutting of the insulation waste through the cooperation of the lower cutter 32 and the upper cutter 31.

[0038] Reference Figures 5-7The limiting component 41 includes a first support 411, a locking block 412, a second guide rod 413, and a second elastic member 414. The first support 411 is mounted on the mounting plate 3. The locking block 412 is connected to the second guide rod 413, and the second guide rod 413 is slidably engaged with the first support 411. An annular groove 332 that engages with the locking block 412 is provided on the first guide rod 413. The second elastic member 414 is sleeved on the second guide rod 413. A second limiting block 4131 is provided at one end of the second guide rod 413 away from the locking block 412. The two ends of the second elastic member 414 are respectively connected to the second limiting block 4131 and the first support 411.

[0039] This invention achieves the function of restricting the upward movement of the first guide rod 33 through the first support 411, the locking block 412, the second guide rod 413, and the second elastic element 414. During the cutting of the insulation layer, the locking block 412 and the second guide rod 413 are in an extended state under the elastic force of the second elastic element 414, which acts as a tension spring. The locking block 412 engages with the annular groove 332 of the first guide rod 33, thereby restricting the upward movement of the first guide rod 33. When the cable 5 stops moving forward, the control component 42 controls the first support 411 to move away from the first guide rod 33. The first support 411 drives the second guide rod 413 and the locking block 412 to move through the second elastic element 414 until the locking block 412 separates from the annular groove 332, releasing the restriction component 41 from restricting the movement of the first guide rod 33. Then, the first guide rod 33 and the lower cutter 32 move upward under the elastic force of the first elastic element 34 to perform the cutting operation.

[0040] Reference Figure 5 , Figure 6 , Figure 9 and Figure 10 The control component 42 includes a first connecting rod 421 and a second connecting rod 422; the first connecting rod 421 is connected to the first support 411, and a vertical plate 4211 is provided on the first connecting rod 421; the second connecting rod 422 is connected to the vertical plate 4211; a third elastic member 4212 is provided on the vertical plate 4211, and the two ends of the third elastic member 4212 are respectively connected to the vertical plate 4211 and the mounting plate 3.

[0041] This invention achieves the function of controlling the movement of the first support 411 through the first connecting rod 421, the upright plate 4211, the third elastic element 4212, and the second connecting rod 422, thereby releasing the restriction component 41 on the lifting and lowering of the first guide rod 33. A square through hole is provided on the mounting plate 3. The upright plate 4211 and the third elastic element 4212 are both located within the square through hole, and the third elastic element 4212 is connected to the inner wall of the through hole. The second connecting rod 422 and the first connecting rod 421 are located on the upper and lower sides of the mounting plate 3, respectively. When the cable 5 stops moving forward, the operator pushes the second connecting rod 422. The second connecting rod 422 drives the first connecting rod 421 and the first support 411 to move through the upright plate 4211. The first support 411 drives the second guide rod 413 and the locking block 412 to move through the second elastic element 414, until the locking block 412 separates from the annular groove 332, releasing the restriction component 41 on the movement of the first guide rod 33.

[0042] Reference Figure 4 A screw 222 is rotatably mounted on the sleeve 22, and a bolt 223 is connected to the sleeve 22; the screw 222 is fixedly connected to the cutting blade 221, and the screw 222 is threadedly connected to the bolt 223.

[0043] This invention achieves the function of adjusting the cutting depth of the cutting blade 221 through the screw 222 and bolt 223. When cutting the insulation layer, the cutting depth of the cutting blade 221 needs to be adjusted according to the diameter of the insulation layer of the cable 5. The operator rotates the screw 222, while the bolt 223 is fixedly connected to the sleeve 22 and threadedly connected to the screw 222. When the screw 222 rotates, it drives the cutting blade 221 to move synchronously along the radial direction of the sleeve 22, thereby adjusting the cutting depth of the cutting blade 221. This allows the cutting blade 221 to stably cut the insulation layer at the specified position. Furthermore, through the cooperation of multiple cutting mechanisms 2, the outer and inner insulation layers can be cut sequentially.

[0044] Reference Figure 4 and Figure 8 The frame 1 is provided with a second support 23, and the second support 23 is provided with a clamp 231 for obstructing the movement of the cable 5; the second support 23 is provided with a first linear driver for driving the clamp 231 to move; the frame 1 is provided with a transmission assembly 24, and the clamp 231 is connected to the second connecting rod 422 through the transmission assembly 24. When the clamp 231 retracts, it abuts against the cable 5, and at the same time, the clamp 231 pushes the second connecting rod 422 to move away from the cable 5 through the transmission assembly 24.

[0045] This invention, through the second support 23 and the transmission assembly 24, achieves the function of automatically releasing the movement restriction component 41 on the first guide rod 33 when the cable 5 stops moving. When cutting the insulation waste, the operator's built-in first linear actuator in the second support 23 drives the clamping block 231 to retract until the clamping block 231 abuts against the cable 5, and the friction between the clamping block 231 and the cable 5 hinders the movement of the cable 5. Simultaneously, the clamping block 231, when moving, drives the second connecting rod 422 to move. The second connecting rod 422, through the upright plate 4211 and the first connecting rod 421, drives the first support 411 to move, thus releasing the movement restriction component 41 on the first guide rod 33.

[0046] Reference Figure 4 and Figure 8 The transmission assembly 24 includes a second hinge seat 241, a third hinge seat 242, and a transmission rod 243. The second hinge seat 241 and the third hinge seat 242 are respectively mounted on the clamping block 231 and the mounting plate 3. A straight groove is provided on the second hinge seat 241. One end of the transmission rod 243 is movably hinged to the straight groove of the second hinge seat 241, and the other end of the transmission rod 243 is hinged to the third hinge seat 242. A pressure block 423 is provided on the mounting plate 3. A third guide rod 4231 is connected to the pressure block 423. A fourth elastic element 4232 is sleeved on the third guide rod 4231. Both ends of the fourth elastic element 4232 are respectively connected to the pressure block 423 and the mounting plate 3. A wedge block 4221 is provided on the second connecting rod 422. When the pressure block 423 moves down, it squeezes the wedge block 4221 and pushes the second connecting rod 422 to move.

[0047] This invention achieves the function of controlling the movement of the second connecting rod 422 when the clamping block 231 moves through the second hinge seat 241, the third hinge seat 242, the transmission rod 243, and the pressure block 423. When the first linear actuator built into the second support 23 drives the clamping block 231 to retract, the clamping block 231 drives the second hinge seat 241 to move. The second hinge seat 241 drives the transmission rod 243 to swing downward, and then the transmission rod 243 presses down on the pressure block 423. The fourth elastic element 4232 is compressed, and the pressure block 423 squeezes the wedge block 4221 on the second connecting rod 422, thereby pushing the second connecting rod 422 to move.

[0048] Reference Figure 5 and Figure 6 A movable guide rail 35 is slidably mounted on the mounting plate 3. A first hinge seat 351 is slidably mounted on the movable guide rail 35. A first connecting rod 352 and a second connecting rod 353 are rotatably mounted on the first hinge seat 351. The first connecting rod 352 and the second connecting rod 353 are hinged to the upper cutter 31 and the lower cutter 32, respectively. A second linear actuator 36 is provided on the frame 1. The driving end of the second linear actuator 36 is connected to a push plate 361 for pushing the movable guide rail 35 to move.

[0049] This invention achieves the function of resetting the lower cutter 32 through the movable guide rail 35 and the second linear actuator 36. After the insulation waste is cut off, the first linear actuator built into the second support 23 drives the clamping block 231 to reset. The clamping block 231 drives the second hinge seat 241 and the transmission rod 243 to reset, and the transmission rod 243 no longer pushes the pressure block 423. Then, the second linear actuator 36 is activated, which drives the push plate 361 to move towards the mounting plate 3. After the push plate 361 contacts the movable guide rail 35, it pushes the movable guide rail 35. The movable guide rail 35 drives the first hinge seat 351 to move, and then pushes the first connecting rod 352 and the second connecting rod 353 to rotate through the first hinge seat 351. Since the upper cutter 31 is fixed in position, it will push the lower cutter 32 to move down until the lower cutter 32 is reset.
