Description

Technical Field

[0001] This invention belongs to the field of resource recycling technology, and in particular relates to a stripping machine for recycling waste cables. Background Technology

[0002] In the field of resource recycling and reuse, the recycling and disposal of waste cables has significant economic value and environmental significance. Waste cables contain a large amount of recyclable metal cores such as copper and aluminum, as well as plastic sheaths. Effective recycling and disposal can not only conserve mineral resources but also reduce environmental pollution caused by the indiscriminate disposal of waste cables.

[0003] In the recycling and processing of waste cables, stripping is a crucial step, aiming to separate the metal core from the outer insulation for separate recycling. However, existing mechanical stripping machines still have some shortcomings. For example, some stripping machines cannot automatically adjust the position and depth of the stripping blades according to the cable diameter. When processing cables of different diameters, frequent manual adjustments of the blade parameters are required, which is cumbersome and prone to incomplete stripping (incomplete removal of the outer insulation) or over-stripping (damaging the metal core), affecting recycling quality and efficiency. Furthermore, some stripping machines have poor cable positioning, causing cables to easily shift during transport, resulting in inaccurate stripping positions and further reducing the stripping effect. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of existing technologies, the waste cable stripping machine of the present invention has significant advantages. It can automatically adapt to cables of different diameters, and achieves positioning and fixation through the diameter measuring hopper and linkage structure to ensure stable cable transportation. With the help of the hydraulic linkage system, the stripping depth can be automatically adjusted according to the cable diameter to avoid incomplete stripping or damage to the metal core, thus ensuring recycling quality. The overall automation level is high, with motor drive achieving automatic transportation, and linkage of each link reducing manual intervention, reducing labor intensity, and improving large-scale processing efficiency, making it suitable for high-efficiency recycling scenarios.

[0005] The technical solution adopted in this invention is as follows: A stripping machine for recycling waste cables includes a mounting base, a support platform fixedly mounted on the top of the mounting base, a support frame one fixedly mounted on the top of the mounting base, symmetrically arranged grooves on the inner side of the support frame one, a limiting slider slidingly mounted in the grooves, a measuring diameter bucket fixedly mounted between the two limiting sliders, one side of the measuring diameter bucket being sloped, the measuring diameter bucket measuring the diameter of the cable and keeping the cable tightly against the upper surface of the support platform, a support column fixedly mounted on the measuring diameter bucket, a blade holder slider slidingly mounted on the support column, a stripping blade rotatably mounted at the end of the blade holder slider away from the measuring diameter bucket, the blade holder slider sliding on the support column adjusting the height of the stripping blade to adjust the cutting depth of the stripping blade, a support frame two fixedly mounted on the measuring diameter bucket, a hydraulic telescopic rod one fixedly mounted on the measuring diameter bucket, a hydraulic telescopic rod two fixedly mounted on the top and bottom walls of the support frame two, the movable end of the hydraulic telescopic rod two fixedly connected to the blade holder slider, the base end of the hydraulic telescopic rod one and the base end of the hydraulic telescopic rod two connected via a hydraulic transmission pipe. The system is hydraulically connected. A pressing rod is fixed to the top and bottom wall of the support frame. This pressing rod retracts the movable end of the hydraulic telescopic rod one. Through hydraulic transmission via a hydraulic transmission pipe, the movable end of the hydraulic telescopic rod two extends, causing the tool holder slider to move downwards relative to the support column, thus increasing the cutting depth of the wire stripper. A spring is fixed between the base end of the hydraulic telescopic rod two and the tool holder slider. When the movable end of the hydraulic telescopic rod one is not in contact with the pressing rod, the movable end of the hydraulic telescopic rod two is in a retracted state. Hydraulic oil is injected into the base ends of both hydraulic telescopic rods one and two. The diameter of the movable end of the hydraulic telescopic rod one is smaller than that of the movable end of the hydraulic telescopic rod two, ensuring that the descent distance of the movable end of the hydraulic telescopic rod two is less than that of the movable end of the hydraulic telescopic rod one. While a larger cable diameter results in a thicker sheath, the change in thickness is less than the change in cable diameter. The smaller descent distance of the movable end of the hydraulic telescopic rod two compared to the movable end of the hydraulic telescopic rod one ensures that the change in cutting depth is less than the change in cable diameter, preventing damage to the tool due to excessive cutting depth.

[0006] As a preferred technical solution of this invention, a second transmission column is symmetrically rotated on the measuring diameter bucket. A swing rod is fixed at the bottom of the second transmission column. When the cable passes through the support platform, it can drive the swing rod and thus drive the second transmission column to rotate. A connecting rod is fixed at the top of the second transmission column. A sliding sleeve is symmetrically slidably mounted on the side wall of the measuring diameter bucket. A serrated rod is slidably mounted inside the sliding sleeve. The end of the serrated rod away from the sliding sleeve is serrated. A fixed tooth is fixed inside the sliding groove. The contact between the serrated rod and the fixed tooth can fix the measuring diameter bucket and restrict its vertical movement. A first transmission column is fixed at the end of the sliding sleeve away from the serrated rod. The first transmission column is located inside the connecting rod. A second spring is fixed between the inner wall of the sliding sleeve and the serrated rod. The cable drives the swing rod to rotate, which in turn drives the second transmission column to rotate. The rotation of the second transmission column can drive the connecting rod to rotate. The connecting rod drives the first transmission column to move, which in turn drives the sliding sleeve to slide toward the limiting slider, thus driving the serrated rod to contact the fixed tooth. The second spring can ensure that the serrated rod is tightly attached to the fixed tooth.

[0007] As a preferred technical solution of this invention, a motor is fixedly mounted on the top of the mounting base, and a feeding roller is coaxially fixed on the output shaft of the motor. The surface of the feeding roller is evenly arranged with metal spikes, which can penetrate the cable sheath and thus move the cable to the support platform. A support block is fixedly mounted on the top of the mounting base, and a support roller is rotatably mounted on one side of the support block. A synchronous belt is fitted between the output shaft of the motor and the rotating shaft of the support roller. The support roller is located directly below the wire stripper and supports the cable to ensure that the wire stripper can cut into the cable sheath.

[0008] The beneficial effects of the present invention after adopting the above structure are as follows:

[0009] (1) It can automatically adapt to cables of different diameters without the need for frequent manual adjustments. By measuring the contact between the diameter bucket and the cable, the height is self-adaptive. With the linkage of structures such as swing rod, connecting rod, and sawtooth rod, it can automatically complete the positioning and fixation when the cable enters the stripping area, ensuring that cables of different diameters can be conveyed close to the support platform, laying the foundation for subsequent accurate stripping and greatly improving the equipment's ability to handle diverse cables;

[0010] (2) It can automatically adjust the stripping depth according to the cable diameter, resulting in better stripping effect. With the help of the hydraulic linkage structure of hydraulic telescopic rod one, hydraulic telescopic rod two and hydraulic transmission pipe, the cable diameter changes drive the measuring diameter bucket to rise and fall, and then trigger the hydraulic transmission through the squeezing rod to realize the automatic adjustment of the stripping knife's cutting depth. At the same time, by utilizing the difference in diameter of the movable end of the hydraulic telescopic rod, the cutting depth is adapted to the relationship between the sheath thickness and the cable diameter, effectively avoiding the problem of incomplete stripping or damage to the metal core, and ensuring the recycling quality;

[0011] (3) The overall structure is reasonably designed and highly automated, which improves the wire stripping efficiency. The feeding roller and the support roller are driven by a motor to operate synchronously, realizing the automatic feeding of the cable; the measurement, positioning, and wire stripping depth adjustment are all completed automatically through mechanical linkage, reducing manual intervention and labor intensity. It is suitable for large-scale waste cable recycling and processing scenarios, and significantly improves the continuity and efficiency of wire stripping operations. Attached Figure Description

[0020] Example 1, as Figures 1-6As shown, the wire stripping machine for recycling waste cables in this embodiment includes a mounting base 1. A support platform 25 is fixedly mounted on the top of the mounting base 1. A support frame 4 is fixedly mounted on the top of the mounting base 1. Sliding grooves 27 are symmetrically opened on the inner side of the support frame 4. Limiting sliders 11 are slidably mounted in the sliding grooves 27. A measuring diameter bucket 5 is fixedly mounted between the two limiting sliders 11. One side of the measuring diameter bucket 5 is sloped. The measuring diameter bucket 5 can measure the diameter of the cable and make the cable fit tightly against the upper surface of the support platform 25. A support column 20 is fixedly mounted on the measuring diameter bucket 5. A blade holder slider 19 is slidably mounted on the support column 20. A wire stripper 6 is rotatably mounted on the end of the tool holder slider 19 away from the measuring diameter bucket 5. The tool holder slider 19 slides on the support column 20 to adjust the height of the wire stripper 6, thereby adjusting its cutting depth. A second support frame 10 is fixedly mounted on the measuring diameter bucket 5, and a first hydraulic telescopic rod 15 is also fixedly mounted on the bucket 5. A second hydraulic telescopic rod 16 is fixedly mounted on the top and bottom walls of the second support frame 10. The movable end of the second hydraulic telescopic rod 16 is fixedly connected to the tool holder slider 19. The base end of the first hydraulic telescopic rod 15 and the base end of the second hydraulic telescopic rod 16 are hydraulically connected via a hydraulic transmission pipe 17. A pressing rod 26 is fixedly installed on the top bottom wall of frame 4. The pressing rod 26 can press the movable end of hydraulic telescopic rod 15 to retract. After hydraulic transmission via hydraulic transmission pipe 17, the movable end of hydraulic telescopic rod 26 can extend, thereby driving the knife holder slider 19 to move downward relative to the support column 20, increasing the cutting depth of the wire stripper 6. A spring 18 is fixedly installed between the base end of hydraulic telescopic rod 26 and the knife holder slider 19. When the movable end of hydraulic telescopic rod 15 is not in contact with the pressing rod 26, the movable end of hydraulic telescopic rod 26 is in a retracted state, and the hydraulic telescopic... Hydraulic oil is injected into the base ends of rod 15 and hydraulic telescopic rod 26. The diameter of the movable end of hydraulic telescopic rod 15 is smaller than that of hydraulic telescopic rod 26. This ensures that the descent distance of the movable end of hydraulic telescopic rod 216 is less than that of the movable end of hydraulic telescopic rod 15. The larger the cable diameter, the thicker its sheath, but the change in thickness is less than the change in cable diameter. The fact that the descent distance of the movable end of hydraulic telescopic rod 216 is less than that of the movable end of hydraulic telescopic rod 15 ensures that the change in depth of cut is less than the change in cable diameter, thus avoiding damage to the tool caused by excessive depth of cut.

[0021] The measuring diameter bucket 5 is symmetrically equipped with a second transmission column 23, which rotates around the measuring diameter bucket 5. A swing rod 24 is fixed at the bottom of the second transmission column 23. When the cable passes through the support platform 25, it can drive the swing rod 24 and thus drive the second transmission column 23 to rotate. A connecting rod 13 is fixed at the top of the second transmission column 23. A sliding sleeve 21 is symmetrically slidably provided on the side wall of the measuring diameter bucket 5. A serrated rod 12 is slidably provided inside the sliding sleeve 21. The end of the serrated rod 12 away from the sliding sleeve 21 is serrated. A fixing tooth 28 is fixed inside the sliding groove 27. The contact between the serrated rod 12 and the fixing tooth 28 can complete the fixation of the measuring diameter bucket 5. To restrict its up and down movement, a transmission column 14 is fixedly provided at the end of the sliding sleeve 21 away from the sawtooth rod 12. The transmission column 14 is located inside the connecting rod 13. A spring 22 is fixedly provided between the inner wall of the sliding sleeve 21 and the sawtooth rod 12. The cable drives the swing rod 24 to rotate, which in turn drives the transmission column 23 to rotate. The rotation of the transmission column 23 can drive the connecting rod 13 to rotate. The connecting rod 13 drives the transmission column 14 to move, which in turn drives the sliding sleeve 21 to slide toward the limiting slider 11, which in turn drives the sawtooth rod 12 to contact the fixed tooth 28. The spring 22 can ensure that the sawtooth rod 12 is tightly attached to the fixed tooth 28.

[0022] The mounting base 1 has a motor 2 fixedly mounted on its top. A feed roller 3 is coaxially fixed on the output shaft of the motor 2. The surface of the feed roller 3 is evenly arranged with metal spikes that can penetrate the cable sheath and move the cable to the support platform 25. A support block 8 is fixedly mounted on the top of the mounting base 1. A support roller 7 is rotatably mounted on one side of the support block 8. A synchronous belt 9 is fitted between the output shaft of the motor 2 and the rotating shaft of the support roller 7. The support roller 7 is located directly below the wire stripper 6 and supports the cable to ensure that the wire stripper 6 can cut into the cable sheath.

[0023] In practical use: Start motor 2, which drives the feeding roller 3 to rotate. Place the waste cable on the feeding roller 3, and the feeding roller 3 will move the cable to the support platform 25. During this process, the cable will contact the inclined surface of the measuring diameter bucket 5, causing the measuring diameter bucket 5 to move upward until the cable reaches the bottom of the measuring diameter bucket 5. The cable will then contact the swing rod 24, causing the swing rod 24 to rotate. The rotation of the swing rod 24 will cause the transmission column 23 to rotate, which in turn will cause the connecting rod 13 to rotate. The rotation of the connecting rod 13 will drive the sliding sleeve 21 to slide towards the limit slider 11 via the transmission column 14. The sliding sleeve 21 will cause the serrated rod 12 to move towards the fixed tooth 28, thus tightly adhering to the fixed tooth 28. The serrations of the serrated rod 12 and the fixed tooth 28 will mesh with each other to fix the measuring diameter bucket 5, preventing it from moving up and down. After that, the measuring diameter bucket 5 can ensure that the cable moves tightly against the support platform 25, ensuring that the subsequent wire stripping is carried out smoothly. The upward movement of the measuring diameter bucket 5 can drive the support frame 12 to rotate. The upward movement of the support frame 10 drives the hydraulic telescopic rod 16 and the blade holder slider 19 to move upward, which in turn drives the wire stripper 6 to move upward to adapt to the cable diameter. The above process completes the automatic limiting of the device for cables of different diameters and the automatic adjustment of the blade position. When the cable passes between the wire stripper 6 and the support roller 7, the wire stripper 6 can strip the cable. At the same time, taking into account the characteristic that the larger the cable diameter, the thicker the outer sheath, during the upward movement of the measuring diameter bucket 5, the hydraulic telescopic rod 15 moves upward, so that the movable end of the hydraulic telescopic rod 15 contacts the extrusion rod 26 and then retracts. The retracted movable end of the hydraulic telescopic rod 15 drives the movable end of the hydraulic telescopic rod 16 to extend through the hydraulic transmission pipe 17. The extended movable end of the hydraulic telescopic rod 16 drives the blade holder slider 19 to move downward relative to the support column 20, which in turn drives the wire stripper 6 to move downward relative to the measuring diameter bucket 5, increasing the cutting depth of the wire stripper 6 and allowing it to cut through a thicker outer sheath.

[0024] In summary, if a person skilled in the art, inspired by this invention, designs a similar structure and embodiment without departing from the spirit of the invention, such design should fall within the scope of protection of this invention.
