[0037] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0038] As Figure 1-12 shown, a cable stripping machine based on cable production includes a cable 5 composed of a core 51, an armor layer 52, and a glue layer, and includes:

[0039] A conveyor unit 1 for conveying the cable 5;

[0040] A core wire separating mechanism 2 for separating the core 51 and the glue layer;

[0041] An armor separating mechanism 3, which includes a concave roller 31 and a convex roller 33, and a coupled concave docking part 32 and a convex shaft 34 are respectively arranged on the two of them. The concave roller 31 and the convex roller 33 rotate and couple to squeeze the glue layer to drive the armor layer 52 on the glue layer to bend and warp;

[0042] An armor separating roller set 30 for separating the warped armor layer 52 and the glue layer.

[0043] Specifically, the conveying unit 1 includes an active conveying roller 11 and an auxiliary stretching roller 12. The active conveying roller 11 is driven by a motor to rotate. After the cable 5 enters the active conveying roller 11 and the auxiliary stretching roller 12, it is cut and conveyed to the skin wire separation mechanism 2 to separate the battery core 51 and the rubber layer of the cable 5. At this time, the armor layer 52 will adhere to the rubber layer, and the spirally wound metal sheet armor layer 52 will be separated into a sheet as the rubber layer is cut, so that the sheet armor layer 52 is rotated and coupled and squeezed by the concave roller 31 and the convex roller 33. It will bend at a large angle, making it difficult for the armor layer 52 to rebound and deform, forming a separated armor sheet 521, so that the separated armor sheet 521 and the rubber layer are separated by the subsequent armor separation roller group 30.

[0044] It also includes a support group 6, which is composed of a plurality of brackets to support and fix the conveying unit 1, the skin-wire separation mechanism 2, the armor-skin separation mechanism 3 and the armor separation roller group 30. The auxiliary stretching roller 12 is movably arranged on the auxiliary frame 121, and the auxiliary frame 121 is provided with a pushing member 122 for pushing the auxiliary stretching roller 12, and the pushing member 122 can be a spring.

[0045] Furthermore, the armored separation roller group 30 includes two roller bodies made of metal material, the two roller bodies are coupled to transport the rubber layer and separate the raised armor layer 52 of the sheet metal. A separation bracket 63 is provided on the support group 6, and the armored separation roller group 30 is provided on the separation bracket 63.

[0046] Furthermore, a slot 311 is provided on the recessed roller 31 , and the recessed docking portion 32 is clamped in the slot 311 for fixation. The recessed docking portions 32 of different sizes can be replaced to accommodate cables 5 of different specifications.

[0047] In the above technical solution, after the cable 5 is separated by the skin-wire separation mechanism 2, the rubber layer carrying the armor layer 52 is transported between the recessed roller 31 and the raised roller 33, and the armor layer 52 is squeezed by the recessed docking portion 32 and the raised shaft 34. At this time, the metal sheet-like armor layer 52 will bend and deform due to excessive extrusion, and the rubber layer will recover due to its good elasticity. The deformed and raised armor layer 52 is peeled off by the armor separation roller group 30 for subsequent recycling.

[0048] As an embodiment provided by the present invention, the armor layer 52 also includes a metal strip, the raised shaft 34 is movably connected to the raised roller 33, and the raised shaft 34 is provided with slots 341 in a linear array, and the slots 341 clamp the metal strip with the coupling movement.

[0049] Specifically, the armored layer 52 also includes a style of metal strips. Multiple metal strips surround the battery cell 51. A limiting protrusion 321 corresponding to the slot 341 is provided on the concave docking portion 32. When the armored layer 52 in the form of metal strips enters the concave roller 31 and the convex roller 33 together with the glue layer as it separates with the cord separating mechanism 2, as the concave roller 31 and the convex roller 33 are coupled and squeezed, the metal strips will be squeezed into the slot 341 along with the coupling. And as the convex roller 33 continues to rotate, the armored layer 52 in the form of metal strips will be separated from the glue layer. The separated metal strip armored layer 52 can be recycled through other winding devices (the winding device can be a winder).

[0050] Further, the convex shaft 34 is slidably connected to the movable slot 331 opened on the convex roller 33. Limiting plates 35 are provided on both sides of the convex roller 33. A pushing plate 351 for pushing against the convex shaft 34 is provided on the limiting plate 35 through an elastic member (the elastic member can be a spring). The pushing plate 351 keeps the convex roller 33 capable of moving slightly along the movable slot 331, so as to snap the armored layer 52 in the form of metal strips into the slot 341. The convex shaft 34 can be replaced to adapt to different specifications of the armored layer 52.

[0051] As an embodiment provided by the present invention, the cord separating mechanism 2 includes a cord separating roller 21. Retaining knives 22 are movably arranged in a circumferential array on the cord separating roller 21. The retaining knives 22 rotate with the cord separating roller 21 and insert into the glue layer.

[0052] Specifically, barbs are provided on the retaining knives 22 to increase the retaining ability. The cord separating roller 21 is rotatably connected to the cord support 62 on the support group 6 and is driven by a motor. When the cut cable 5 passes through the cord separating roller 21, the retaining knives 22 on the rotating cord separating roller 21 will insert into the glue layer, peeling the glue layer and the armored layer 52 from the battery cell 51. By fixing the glue layer with the inserted retaining knives 22, the cable 5 in the symmetric cutting mode can be evenly separated, and it is also convenient for the subsequent separation of the glue layer and the armored layer 52.

[0053] As an embodiment provided by the present invention, the retaining knife 22 extends as it rotates to a predetermined position to drive the glue layer to move towards the armor-cable separating mechanism 3.

[0054] Specifically, after the retaining knife 22 punctures the glue layer and rotates to a predetermined position (the predetermined position is when facing the armor separating roller set 30), the retaining knife 22 extends to convey the glue layer carrying the armored layer 52 towards the armor separating roller set 30 for subsequent separation operations. When inserting a new cable 5, manual traction is not required, which is relatively safe.

[0055] Furthermore, the leather wire separation mechanism 2 also includes a fixed shaft 23 which is fixedly arranged and passes through the central axis of the leather wire separation roller 21. A slide groove 211 is opened on the leather wire separation roller 21. The retention knife 22 is slidably connected to the slide groove 211. A pulling member 223 (the pulling member 223 can be a tension spring) is arranged between the retention knife 22 and the inner wall of the leather wire separation roller 21. A cam 231 is arranged on the fixed shaft 23. The pulling member 223 pulls the retention knife 22 to fit the cam 231. As the leather wire separation roller 21 rotates, the retention knife 22 extends along the cam 231, and the rubber layer on the retention knife 22 is transported to the armor skin separation mechanism 3.

[0056] As an embodiment provided by the present invention, the retention knife 22 includes a supporting frame 221 and a sliding knife head 222 slidably connected to the supporting frame 221, and a force storage member is arranged between the two. The sliding knife head 222 is compressed and popped out as the leather wire separation roller 21 rotates to penetrate the rubber layer.

[0057] Specifically, the force storage member arranged between the supporting frame 221 and the sliding blade head 222 can be a spring. When the retention blade 22 rotates with the skin wire separation roller 21 to transport the rubber layer on the retention blade 22 to the armor skin separation mechanism 3, as the sliding blade head 222 continues to rotate and move, it will slide along the supporting frame 221 to compress the force storage member and be restricted. When it then contacts the rubber layer again, the restriction is cancelled to pop out the sliding blade head 222, and the sliding blade head 222 is inserted into the rubber layer. The rubber layer is inserted through a quick pop-up action to reduce the wear of the sliding blade head 222, and the puncture, insertion and fixing ability is strong.

[0058] Furthermore, the leather wire separation mechanism 2 also includes a compression guide plate 24, which is arranged on the leather wire bracket 62 and is fixed. When the sliding blade head 222 rotates with the leather wire separation roller 21, the sliding blade head 222 will be restricted by the compression guide plate 24, thereby sliding and compressing along the supporting frame 221. When leaving the compression guide plate 24, the sliding blade head 222 pops out to implement the puncture step.

[0059] As an embodiment provided by the present invention, it also includes a cutting assembly 4, which includes a symmetrical rotating roller 41. The rotating roller 41 is movably provided with a cutting blade 42. The cutting blade 42 cuts into the glue layer and deviates to be staggered with the metal strip.

[0060] Specifically, the support group 6 includes a conveying support frame 61, and the cutting component 4 includes a sliding frame 44 for rotating and fixing the rotating roller 41. The sliding frame 44 is slidably connected to the conveying support frame 61, and a push spring 441 is arranged between the two. The push spring 441 pushes the sliding frame 44 to drive the cutting blade 42 to fit the cable 5 for cutting. An elastic ring 421 is arranged on the inner wall of the cutting blade 42 to limit the movable cutting blade 42, so that the rubber layer can be cut at the same time, the metal strip can be staggered when cutting, and the metal sheet can be cut directly.

[0061] Furthermore, an active annular groove 411 is formed in the rotating roller 41. A limiting frame 43 is arranged in the active annular groove 411. The cutting blade 42 is rotatably connected in the active annular groove 411. The elastic ring 421 fits the active annular groove 411, thereby providing the freedom for the cutting blade 42 to move in the active annular groove 411 and being restricted by the elastic ring 421 at the same time. The limiting frame 43 is made of elastic metal. A control pressing plate 431 is arranged on the limiting frame 43. The control pressing plate 431 is restricted by screws and nuts. By rotating the nut, the limiting frame 43 is closed to reduce the moving space of the cutting blade 42, so as to restrict the movement of the cutting blade 42 to cope with the cutting of metal strips and metal sheets.

[0062] First, adjust according to the type of the armor layer 52 of the cable 5 to be cut. When the armor layer 52 is a metal sheet wound, rotate the nut to close the limiting frame 43 to reduce the moving space of the cutting blade 42 and restrict the movement of the cutting blade 42. At this time, cut the metal sheet. When the armor layer 52 is a metal strip, rotate the nut to expand, so that the cutting blade 42 can offset along the active annular groove 41, so as to stagger the metal strip during cutting and only cut the glue layer. Subsequently, the cut cable 5 is conveyed to the cord separating roller 21. The sliding cutter head 222 will be restricted by the compression guide plate 24, so as to slide and compress along the bearing frame 221. When leaving the compression guide plate 24, the sliding cutter head 222 pops out to puncture the glue layer. After puncture, with the rotation of the cord separating roller 21, the retention knife 22 extends along the cam 231, and conveys the glue layer on the retention knife 22 to the armor separating mechanism 3;

[0063] At this time, when the sheet-like armor layer 52 is rotationally coupled and extruded by the concave roller 31 and the convex roller 33, it will bend at a large angle, resulting in difficulty in the armor layer 52 rebounding and deforming, forming separated armor sheets 521. Thus, through the subsequent armor separating roller group 30, the separated armor sheets 521 and the glue layer are separated;

[0064] At this time, the armor layer 52 in the form of a metal strip will be extruded into the slot 341 along with the coupling, and with the continuous rotation of the convex roller 33, the armor layer 52 in the form of a metal strip is separated from the glue layer. The separated armor layer 52 in the form of a metal strip can be wound by other winding devices.

[0065] Only some exemplary embodiments of the present invention are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
