Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to a device for removing the metal conductor from the insulation core of a cable. Background Technology

[0002] As a core carrier in power transmission and communication, the efficient processing of cable insulation is crucial for ensuring equipment maintenance, material recycling, and quality testing. In power system maintenance, the recycling of used cables, and performance testing of new products, precise separation of the insulation layer from the metal conductor is an essential process. For example, before testing cable insulation performance, the internal metal conductor must be completely removed to avoid interfering with test results; in the recycling of used cables, the thorough separation of insulation material from the metal conductor directly affects the purity and value of the recycled resources. However, existing technologies still face significant challenges in achieving this goal, especially the problem of metal debris contamination during the cutting process, which has become a core bottleneck restricting the level of automation and processing quality.

[0003] Chinese document CN115078940A discloses a device for removing the metal conductor of a cable insulation core. It includes a worktable, an ejector mechanism, a fixed clamp, and a traction mechanism. The worktable is supported and fixed by legs. The ejector mechanism, fixed clamp, and traction mechanism are arranged sequentially from left to right and are all located on the upper side of the placement seat. The cable is placed inside the fixed clamp, and the clamp can be controlled by a handle to hold and fix the cable. A hydraulic cylinder drives a piston rod to contact the ejector rod with the internal metal conductor of the cable, gradually squeezing the conductor out from the other end of the cable. A motor drives a reducer, and the reducer's output shaft drives a bevel gear B to rotate via bevel gear A, which in turn drives a drive gear to rotate via a rotating shaft. Under the action of a fixed gear plate, a support plate can be moved to the right, thereby pulling the conductor out from inside the cable. This invention features simple operation, wide applicability, good protective performance, and excellent results.

[0004] The aforementioned cable insulation core metal conductor removal device may generate copper or aluminum shavings during cable insulation cutting. The physical mixing of metal shavings and insulation material forms a heterogeneous structure, damaging the integrity and purity of the insulation material. As a result, the recycled insulation particles cannot be directly used in high-requirement scenarios due to the presence of metal impurities, requiring additional resources for purification. Furthermore, manual cleaning of metal shavings embedded in the insulation layer relies on precision tools and visual identification, making the operation cumbersome and time-consuming, significantly increasing labor intensity and time costs. The residue of metal shavings leads to a decrease in the purity of the recycled insulation material, not only reducing the economic value of the recycled material but also potentially causing secondary pollution or affecting the performance of recycled products due to impurities.

[0021] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0022] Please see Figure 1-8The present invention provides a technical solution: a cable insulation core metal conductor removal device, including a mounting base plate 1 and an auxiliary mechanism. Four sets of mounting cylinders 4 are arranged above the mounting base plate 1. Multiple sets of rollers 6 are arranged above the mounting base plate 1. Two sets of connecting frames 8 are arranged above the mounting base plate 1. Air outlet pipes 10 are arranged inside the two sets of connecting frames 8. A connecting plate 13 is arranged above the mounting base plate 1. A snap-fit ​​groove is opened on the top of the connecting plate 13. A stripping blade 15 is snap-fitted into the snap-fit ​​groove. The auxiliary mechanism includes a movable mechanism 5, a swing mechanism 9, and a quick-release mechanism 14. The swing mechanism 9 is mounted on the first connecting frame 8 and is used to drive the first connecting frame 8 to swing. The swing mechanism 9 includes a connecting rod 901, a hydraulic rod 902, a second connecting frame 903, and a connecting short rod 904. There are two sets of swing mechanisms 9.

The swing mechanism 9 can drive the air outlet duct 10 to swing, thereby increasing the coverage of the air outlet duct 10. This avoids the copper or aluminum shavings generated when cutting the cable insulation layer from mixing into the insulation material, which would cause the metal shavings and insulation material to physically mix and form a heterogeneous structure, damaging the integrity and purity of the insulation material. This improves the recycling purity of the insulation material and increases the economic value of the recycled material.

[0023] The movable mechanism 5 is mounted on the mounting cylinder 4. The movable mechanism 5 is used to drive multiple sets of rollers 6 to adapt to cables of different sizes.

A sliding short rod 504 is fixedly mounted on the bottom of the movable round block 503. The movable mechanism 5 can drive multiple sets of rollers 6 to adapt to cables of different sizes, so as to guide cables of different sizes and protect the cable surface, avoid damage to the cable insulation layer during the cutting and guiding process, and improve the quality of stripping the cable insulation material.

When the stripping blade 15 is damaged after long-term use, the quick-release mechanism 14 can disassemble the stripping blade 15, which facilitates the daily replacement and maintenance of the stripping blade 15, reduces the downtime of the cable insulation core metal conductor removal device, and improves the maintenance efficiency of the cable insulation core metal conductor removal device.

[0025] The inner top and inner bottom of both sets of connecting brackets 8 are rotatably installed with a set of connecting short rods 904, and the interior of both sets of connecting brackets 903 is fixedly installed with the air outlet pipe 10, which can blow air out onto the surface of the cable.

[0026] Multiple sets of movable circular blocks 503 are slidably installed inside the mounting cylinder 4, and one end of multiple sets of sliding short bars 504 extends to the outside of the mounting cylinder 4 and is equipped with rollers 6. The four sets of rollers 6 can adapt to cable surfaces of different sizes, which can improve the applicability of the cable insulation core metal conductor removal device.

[0027] The stripping blade 15 has the same through hole on one side, and the bolt 1402 is slidably installed through the through hole and the stripping blade 15.

[0028] Two sets of fixing rods 2 are fixedly installed on the top of the mounting base plate 1. Mounting rings 3 are fixedly connected to the adjacent sides of the two sets of fixing rods 2. The inner side of the mounting rings 3 is fixedly connected to multiple sets of mounting cylinders 4.

[0029] Mounting bracket 7 is fixedly installed on the top of mounting base plate 1. The inner walls of both sides of mounting bracket 7 are fixedly connected to connecting bracket 8. Fans 17 are fixedly installed on both sides of mounting bracket 7. Connecting hoses 18 are fixedly installed at the output ends of both sets of fans 17. One end of each set of connecting hoses 18 extends into the air outlet pipe 10. The two sets of fans 17 can send air into the air outlet pipe 10 through the connecting hoses 18 and blow it out to the surface of the cable through the air outlet pipe 10, blowing away the copper or aluminum shavings generated by cutting the cable from the surface of the cable.

[0030] A connecting bracket 3 11 is fixedly installed on the top of the mounting base plate 1. A threaded short rod 12 is threadedly connected to the top of the connecting bracket 3 11. One end of the threaded short rod 12 is rotatably installed with the connecting plate 13. The other end of the threaded short rod 12 extends to the bottom of the connecting bracket 3 11 and is fixedly installed with a round handle 16. By rotating the threaded short rod 12 through the round handle 16, the height of the connecting plate 13 can be adjusted, and the height of the stripping blade 15 can be adjusted to a suitable position.

[0031] A material pump 19 and a debris collection box 22 are fixedly installed on the top of the mounting frame 7. The input end of the material pump 19 extends into the interior of the mounting frame 7 and is fixedly installed with a connecting short pipe 20. A suction hopper 21 is fixedly installed at one end of the connecting short pipe 20 and communicates with it. The output end of the material pump 19 extends into the interior of the debris collection box 22. A door is hinged to one side of the debris collection box 22, and a handle is fixedly installed on one side of the door. The suction hopper 21 can suck up copper or aluminum shavings through the connecting short pipe 20 and discharge them into the debris collection box 22. The door on one side of the debris collection box 22 can be opened by the handle, so that the copper or aluminum shavings in the debris collection box 22 can be cleaned.

[0032] Working principle: When work is required, one end of the cable is passed between the four sets of rollers 6 and slides within the mounting cylinder 4 via the movable block 503. This compresses the damper 501 and the high-pressure spring 502, thereby driving the sliding short rod 504 to move. This allows the four sets of rollers 6 to adapt to cable surfaces of different sizes. One end of the cable is then connected to the traction device. By rotating the threaded short rod 12 through the circular handle 16, the height of the connecting plate 13 can be adjusted, and the height of the stripping blade 15 can be adjusted to a suitable position. The suction pump 19 and two sets of fans 17 are then started. The two sets of fans 17 can deliver air through the connecting hose 18 into the air outlet pipe 10, and through the air outlet pipe 1... The material is blown onto the cable surface, removing copper or aluminum shavings generated during cable cutting. At this time, the suction hopper 21 can suck in the copper or aluminum shavings through the connecting short pipe 20 and discharge them into the debris collection box 22. When the stripping blade 15 is damaged and needs maintenance and replacement, the two sets of nuts 1403 are rotated to separate the nuts 1403 from the bolts 1402, and then the bolts 1402 are pulled out through the through hole. At this time, the stripping blade 15 can be separated from the connecting plate 13 for easy daily maintenance and replacement. The door on one side of the debris collection box 22 can be opened by the handle, so that the copper or aluminum shavings in the debris collection box 22 can be cleaned.
