[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] As Figures 1 to 4 shown, an adjustable sheathing stripping device for cables of the present utility model includes a wire pay-off frame 1, a plurality of brackets 2, a tractor, and a wire take-up frame 4. The brackets 2 are arranged between the wire pay-off frame 1 and the wire take-up frame 4 and are used to support the cable. The tractor is used to guide the movement of the cable. Among them, the stripping device includes: a fixed frame 5, which is arranged between a plurality of brackets 2 and is close to the wire pay-off frame 1. A nylon mold 50 is configured on the fixed frame 5 to prevent the aluminum sheath of the cable to be cut from being deformed; a cutting mechanism 6 and an adjustment frame 7. The cutting mechanism 6 is installed on the adjustment frame 7. The cutting mechanism 6 is provided with a first cutter 60 and a second cutter 61 in the vertical direction. The first cutter 60 and the second cutter 61 can approach or move away from each other, so that the ends of the first cutter 60 and the second cutter 61 are in contact with the radial section of the aluminum sheath to adapt to the outer diameter sizes of different cable aluminum sheaths; the adjustment frame 7 is symmetrically arranged on the side walls of the fixed frame 5 in the vertical direction and is used to drive the two cutting mechanisms 6 to approach the top and bottom of the cable outer sheath in the radial direction respectively; a separation mechanism 8, which is arranged on the side of the cutting mechanism 6 away from the wire pay-off frame 1. A first separation plate 80 and a second separation plate 81 are movably arranged on the separation mechanism 8. When the first separation plate 80 and the second separation plate 81 move towards each other, they are used to adjust the separation distance of the cable aluminum sheath.

[0034] As Figure 1 shown, under normal operating conditions, the cable in the wire pay-off frame 1 moves towards the wire take-up frame 4 through the tractor, and the design of the plurality of brackets 2 is to better support the cable. During this process, in order to realize the peeling of the cable aluminum sheath and the extrusion sheath, the distance between the two cutting mechanisms 6 in the vertical direction can be adjusted in advance. Specifically, as Figures 2 to 3As shown in the figure, when the cable aluminum sheath to be stripped is limited by the nylon mold 50 and passes through between the two cutting mechanisms 6, the two cutting mechanisms 6 in the vertical direction can be moved closer to each other by adjusting the movement of the adjusting frame 7 relative to the fixed frame 5. This structure is similar to the rapid tool alignment of a machine tool, which is beneficial to saving the overall production cycle time. As the cutting mechanism 6 drives the first cutter 60 and the second cutter 61 to further approach the cable aluminum sheath, the distance between the first cutter 60 and the second cutter 61 is made smaller than the outer diameter of the cable aluminum sheath (i.e., the end of the cutter is inside the cross-section of the aluminum sheath). Finally, with the traction of the cable by the tractor, the cable aluminum sheath is peeled off. This device effectively ensures that the distance between the first cutter 60 and the second cutter 61 can accurately match the diameter of the cable to be stripped and the thickness of the sheath. The overall stability is good, the safety is high, and the adaptability is strong. It avoids damaging the tape during the peeling process, resulting in re-wrapping the tape, reducing the waste of manpower and tape, and at the same time improving the production efficiency. In addition, the first separation plate 80 and the second separation plate 81 can be used to completely separate the cut cable sheath, ensuring that the peeling quality of the cable aluminum sheath meets the required production requirements.

[0035] Preferably, the first cutter 60 and the second cutter 61 in this solution are respectively arranged above and below the fixed frame 5 for cutting the cable aluminum sheath. It should be noted that there are two types of these cutters, which are respectively used for cutting the aluminum sheath and the extruded plastic sheath. An elastic structure (not shown in the figure) can also be installed at the conductor of the extruded plastic sheath cutter to achieve the shrinkage of the aluminum strip hardness, so as to realize cutting according to the shape of the aluminum sheath under the extruded plastic aluminum sleeve. It should be noted that the nylon mold 50 is split in half, and preferably has a size slightly larger than the outer diameter of the aluminum sheath (the maximum is 180 mm) to facilitate the smoother passage of the cable aluminum sheath.

[0036] A fixed mold 52 and a fixed cover 53 are arranged on the fixed frame 5. The nylon mold 50 is arranged in the fixed mold 52, and when the fixed cover 53 is movably pressed against the fixed mold 52, the nylon mold 50 is restricted in the fixed mold 52 by the fixing member 54.

[0037] Regarding the fixation of the cable aluminum sheath, as Figures 2 to 3 shown, when the nylon mold 50 positions and guides the cable aluminum sheath, the fixed cover 53 can be covered on the nylon mold 50 and pressed against the fixed frame 5, and the nylon mold 50 is restricted on the fixed frame 5 under the locking action of the fixing member 54 to ensure the overall stability of the structure. At the same time, it also provides stability for the smoothness and stability during the peeling of the cable aluminum sheath.

[0038] The cutting mechanism 6 further includes: a movable tool holder 62, movably arranged on the adjusting frame 7; an adjusting block 63, movably inserted into the adjusting frame 7 in the vertical direction, and connected to the first cutter 60 or the second cutter 61, for driving the first cutter 60 and the second cutter 61 to approach or move away from each other, so as to adjust the distance difference between the two; a plurality of locking bolts 64, arranged on the movable tool holder 62, and the locking bolts 64 are used to limit the displacement of the first cutter 60 or the second cutter 61 when cutting the cable sheath.

[0039] As Figure 2 shown in Figure 3 the figure, as the adjusting frame 7 drives the two movable tool holders 62 to move, the first cutter 60 and the second cutter 61 can quickly approach the cable aluminum sheath to be peeled, thereby saving the overall time required for the cutter to move to the preset position and improving the production efficiency. When the cutter is close to the cable aluminum sheath, at this time, the worker can adjust the distance difference between the first cutter 60 and the second cutter 61 through the adjusting block 63. When the first cutter 60 and the second cutter 61 respectively extend into the inside of the cutting surface of the cable aluminum sheath, the worker can fix the first cutter 60 and the second cutter 61 through the locking bolts 64. As the above traction machine pulls and moves the cable, the aluminum sheath can be peeled off under the cutting of the first cutter 60 and the second cutter 61. The overall operation is simple, and the sheath can be peeled off more safely, conveniently and efficiently without rewinding the tape. At the same time, the cutter is used to replace the cutting machine for the cutting process of the aluminum sheath, effectively preventing the generation of a large amount of dust and realizing an environmentally friendly and healthy production process.

[0040] Furthermore, in this solution, a linear guide rail (not shown in the figure) is also arranged on the side wall of the fixed frame 5 in the vertical direction, and the output end of the linear guide rail is connected to the adjusting frame 7 to realize the approach or separation of the two cutting mechanisms 6. Of course, the moving mode of the two cutting mechanisms 6 is not limited to the one in this embodiment. The cooperation of a slider and a slide rail can also be adopted, and combined with the structure of the locking bolts 64, the free movement and locking of the cutting mechanism 6 in the vertical direction are realized.

[0041] Preferably, as Figure 2 shown in Figure 3 the figure, a waist-shaped hole 620 is also arranged on the movable tool holder 62, and the waist-shaped hole 620 can be penetrated by the locking bolts 64. That is to say, as the movable tool holder 62 moves, combined with the position adjustment of the cutter relative to the movable tool holder 62, the locking bolts 64 have enough position space to adapt to the first cutter 60 or the second cutter 61 at different positions, thereby ensuring the stability of the first cutter 60 and the second cutter 61 when peeling the aluminum sheath.

[0042] Preferably, as Figure 3As shown in the figure, protective plates 51 are provided at the adjustment frames 7 above and below the fixing frame 5. The adjustment frames 7 drive the two protective plates 51 to approach each other and actively adhere to the outer wall of the cable aluminum sheath, effectively avoiding the shaking phenomenon when the device strips the sheath and improving the stability.

[0043] The separating mechanism 8 further includes a mounting seat 82 and fixing bolts 83. The mounting seat 82 is arranged on the side of the fixing frame 5 away from the wire pay-off frame 1, and a clamping groove 820 is formed in the mounting seat 82. The first separating plate 80 and the second separating plate 81 are movably arranged in the clamping groove 820; the fixing bolts 83 are used to limit the first separating plate 80 and the second separating plate 81 in the clamping groove 820.

[0044] As Figure 4 shown, the above-mentioned first separating plate 80 and second separating plate 81 are arranged in the clamping groove 820 of the mounting seat 82. Relying on the movable clamping cooperation between the two, the distance between the first separating plate 80 and the second separating plate 81 can be freely adjusted according to the actual situation. After the two separating plates are adjusted to the required positions, the separating plates can be fixed in the clamping groove 820 through the fixing bolts 83 on the mounting seat 82 to ensure that the cut cable aluminum sheath can be completely separated by the first separating plate 80 and the second separating plate 81, and to avoid the separated cable aluminum sheaths from winding around each other again, causing secondary separation operations for workers.

[0045] It should be noted that the fixing member 54 in this solution can be replaced by other fixing devices such as bolts and screws.

[0046] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, in the present invention, descriptions such as "first", "second", and "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] In the present utility model, unless otherwise clearly stipulated and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0049] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
