Description

Technical Field

[0001] This invention relates to the field of cable stripping machine technology, and more specifically, to a cable stripping device and method for industrial production. Background Technology

[0002] In the production of industrial cables, some recycled cables are used. Before these waste cables are recycled, they need to be cut into multiple sections, then the outer insulation layer of the cable is cut open with a stripping machine, the internal battery core is removed, and finally the battery core is melted down and reprocessed into a new battery core.

[0003] Traditional cable stripping machines typically feature two symmetrical cutting assemblies, each consisting mainly of a central circular blade and drive rollers on either side of it. During cutting, the rotation of the drive rollers propels the cable linearly, while the rotation of the blade cuts the cable. Although the equipment has a blade gap adjustment function, differences in cable diameter and insulation thickness, coupled with fixed radii for both the blade and drive rollers, mean that when the roller gap is adjusted to match the cable, the cutting depth may exceed the insulation thickness, resulting in the core being severed. In such cases, replacing the blade with a suitable one is usually necessary, but frequent blade changes are cumbersome. Summary of the Invention

This design only requires rotating the screw to complete the adjustment, eliminating the tedious operation of frequent cutting tool replacement. Combined with the spacing adjustment function of the cutting components, it forms a dual adaptive mechanism for the cable outer diameter and insulation layer thickness, improving stripping accuracy and production efficiency.

Detailed Implementation

[0036] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that discussions of these implementations are merely provided to enable those with skill in the art to better understand so as to be able to implement the subject matter described herein, changes to the function and arrangement of elements can be made without departing from the scope of the content as described herein. Various examples can omit, substitute, or add various procedures or components as appropriate, or in appropriate combination. Also, features described with respect to some examples can be combined in other examples.

[0037] Reference will now be made to the drawings Figures 1 to 2 The utility cable stripping device comprises a workbench 100, a conveying mechanism 200 and a stripping mechanism 300. The conveying mechanism 200 is arranged on the workbench 100 and is used to drive the linear movement of the cable 400 to the position of the stripping mechanism 300. The stripping mechanism 300 is mainly used to cut the insulating layer on the cable 400 and comprises a support frame 301, two cutting assemblies, a spacing adjusting assembly and a rotary driving assembly. The spacing adjusting assembly is in transmission connection with the two cutting assemblies and is mainly used to adjust the spacing of the cutting assemblies. By adjusting the spacing of the two cutting assemblies, the cutting assemblies can be adapted to cables 400 of different diameters and can effectively cut the insulating layer of the cable 400. The rotary driving assembly is in transmission connection with the two cutting assemblies and is mainly used to drive the synchronous rotation of the cutting assemblies to complete the cutting work of the insulating layer of the cable 400.

[0038] Reference will now be made to the drawings Figures 2 to 4 The support frame 301 is arranged on the workbench 100, and the two cutting assemblies are symmetrically arranged on the support frame 301. Each cutting assembly comprises a rotating shaft 302, a cutting tool 303 arranged at the middle position of the rotating shaft 302, a driving roller 304 symmetrically arranged at both ends of the rotating shaft 302 and an expansion driving member. The driving roller 304 is composed of a plurality of circumferentially distributed driving bodies in the shape of a horizontal circular cone. The outer side of each driving body is uniformly provided with an anti-skid groove 311, and the outer side is provided with a wear-resistant layer. In the present application, four driving bodies are arranged, and the four driving bodies are in transmission connection with the expansion driving member. The four driving bodies are driven by the expansion driving member to move synchronously along the diameter direction of the rotating shaft 302 to realize the diameter adjustment of the driving roller 304, so as to adapt to the insulating layer of the cable 400 of different thicknesses.

[0039] Specifically, the sliding body is arranged on the rotating shaft 302, and the sliding end of the sliding body is provided with a slope. The sliding end of the sliding body and the rotating shaft 302 are connected with a reset spring 305. The expansion driving member includes a screw rod one 306 with opposite screw directions at two ends, and two top driving blocks 307 with threaded sleeves arranged at two ends of the screw rod. The screw rod one 306 is rotationally arranged in the rotating shaft 302, and one end of the screw rod one 306 extends to the outside of the rotating shaft 302 and is provided with a knob. The two top driving blocks 307 are slidingly arranged in the rotating shaft 302. The top driving block 307 has four contact grooves matched with the sliding body, and the four contact grooves are matched with the four slopes of the sliding body. The inclination angle of the contact grooves of the top driving block 307 and the slopes of the sliding body is 15-30°, so that the radial expansion is more smooth, and the precision is higher.

[0040] When the radius of the driving roller 304 is adjusted by using the expansion driving member, if the radius is increased, the screw rod one 306 is rotationally driven in a forward direction, so that the two top driving blocks 307 are synchronously slid close to each other in the rotating shaft 302. The slope of the sliding body is subjected to the extrusion action of the groove of the top driving block 307, so that the sliding body starts to move outward. The reset spring 305 is synchronously subjected to extrusion and contraction. When the preset radius is reached, the rotation of the screw rod one 306 is stopped. Under the locking action of the screw rod one 306, the top driving block 307 can be locked to maintain the adjusted state of the driving roller 304. If the radius is reduced, the screw rod one 306 is rotationally driven in a reverse direction, so that the two top driving blocks 307 are slid away from each other. Under the elastic force of the reset spring 305, the sliding body is contracted and moved together with the top driving block 307, so that the radius of the driving roller 304 is reduced. In this way, the radius adjustment function of the driving roller 304 is realized. When the thickness of the insulation layer of the cable 400 changes, only the distance between the cutting tools 303 and the radius of the driving roller 304 need to be adjusted, so that the cutting depth of the cutting tools 303 is matched with the thickness of the insulation layer of the cable 400. The cutting tools 303 do not need to be replaced, so that the adjustment difficulty of the cutting assembly is reduced. Meanwhile, the driving rollers 304 on the upper side and the lower side can contact the outer side of the cable 400 and generate a straight-line driving force.

[0041] Please refer to Figure 3 The cutting tools 303 are composed of two half knife bodies which are connected by bolts. The cutting tools 303 can be detachably arranged on the rotating shaft 302, so that the cutting tools 303 are convenient to maintain and replace.

[0042] Please refer to Figures 2 to 3The distance adjusting assembly comprises a screw No. 2 308 and two sliding frames 309 symmetrically sliding on the support frame 301, the screw No. 2 308 is vertically rotatably arranged on the support frame 301, the screw threads of the upper and lower ends of the screw No. 2 308 are opposite, the two rotating shafts 302 are correspondingly rotatably arranged on the two sliding frames 309, and the screw threads of the two ends of the screw No. 2 308 are connected with the sliding ends of the two sliding frames 309. The rotating driving assembly comprises two servo motors 310, one end of each of the two servo motors 310 is connected with one of the two rotating shafts 302, the rotating directions of the two servo motors 310 are opposite, the rotating shaft 302 connected with the servo motor 310 can be driven to rotate through the rotation of the servo motor 310, and finally the cutting tool 303 and the driving roller 304 are driven to rotate, the driving force for the linear movement of the cable 400 is generated through the driving roller 304, and the cutting of the insulating layer of the cable 400 is generated through the cutting tool 303.

[0043] When the distance of the cutting tool 303 is adjusted, the screw No. 2 308 is rotated, the two sliding frames 309 are synchronously driven to move towards each other along the support frame 301, and then the distance of the cutting tool 303 is changed until the distance reaches the required position, that is, the rotation of the screw No. 2 308 is stopped.

[0044] Please refer to Figure 1 and Figure 6 The conveying mechanism 200 comprises two driving rollers 201 fixed on the workbench 100, two driven rollers 202 symmetrically arranged above the driving rollers 201, a linear extension source 204 connected with the driven rollers 202 and a driving box 203 for driving the driving rollers 201. One end of the driving roller 201 is slidably connected with the driving box 203. The linear extension source 204 can be an electric push rod, which is fixedly installed on the workbench 100. The driven roller 202 is driven to ascend and descend by the linear extension source 204 to adjust the distance between the driving roller 201 and the driven roller 202 and adapt to cables 400 with different diameters. The driving box 203 is internally provided with a driving motor and a gear transmission structure, so that the driving rollers 201 can be synchronously rotated. Since it belongs to the prior art, the specific structure is not disclosed here.

[0045] When the cable 400 is conveyed, the distance between the driving roller 201 and the driven roller 202 is adjusted according to the radius of the cable 400. The driven roller 202 is synchronously driven to ascend and descend by the linear extension source 204, so that the distance is changed, and the driving roller 201 and the driven roller 202 can be in close contact with the outside of the cable 400. Then, the cable 400 is passed through the distance between the driving roller 201 and the driven roller 202. The driving roller 201 is driven to rotate by the driving box 203, so that the cable 400 can linearly move and gradually approach the cutting assembly.

[0046] The working process of the above scheme is as follows:

[0047] First, according to the diameter of the cable 400 to be processed, the passive roller 202 is driven to lift by the linear extension source 204, the distance between the active roller 201 and the passive roller 202 is adjusted so that they can be in close contact with the outside of the cable 400. Then, the cable 400 is passed between the active roller 201 and the passive roller 202, the active roller 201 is driven to rotate by the driving box 203, so that the cable 400 moves linearly and approaches the cutting assembly.

[0048] According to the thickness of the insulating layer of the cable 400, the diameter of the driven roller 304 is adjusted. By rotating the screw one 306 in the forward direction, the two top blocks 307 slide synchronously in the shaft 302 to approach each other, the slope of the driven body is extruded by the slope of the top block 307 to move outward, the return spring 305 is contracted, and the diameter of the driven roller 304 is increased; if you want to reduce the diameter, then rotate the screw one 306 in the reverse direction, the top block 307 slides away, the driven body is contracted under the elastic force of the return spring 305, and the diameter of the driven roller 304 is reduced. At the same time, according to the diameter of the cable 400, the screw two 308 is rotated, driving the two sliding frames 309 to move synchronously along the support frame 301, adjusting the distance between the two cutting assemblies, so that the cutting tool 303 can effectively cut the insulating layer of the cable 400.

[0049] By rotating the two servo motors 310 of the rotating driving assembly, the shaft 302 connected with the two servo motors 310 is rotated in the opposite direction, and then the cutting tool 303 and the driven roller 304 are rotated. The driven roller 304 is in contact with the outside of the cable 400, generating a linear driving force on the cable 400, so that the cable 400 continues to move linearly, and the cutting tool 303 cuts the insulating layer of the cable 400. During the cutting process, because the driven roller 304 is uniformly provided with anti-skid grooves 311 on the outside, it can effectively prevent the cable 400 from sliding during transportation and cutting. When the cutting of a section of the cable 400 is completed, the subsequent cable 400 can be processed according to the above steps to realize the efficient stripping of the cable 400 in industrial production.

[0050] The above describes the embodiments of the present application, but the present application is not limited to the above specific embodiments, the above specific embodiments are only illustrative and not restrictive, and those skilled in the art can make many forms under the inspiration of the present application, which all belong to the protection of the present application.
