Technical Field
[0001] This utility model relates to the technical field of cable stripping machines, specifically a cable insulation stripping machine. Background Technology
[0002] During cable recycling, the insulation layer and metal layer can be separated by mechanical stripping or burning stripping. However, burning causes significant environmental pollution. Therefore, most cables are stripped of their insulation layer using cable stripping machines during recycling.
[0003] For example, publication number CN109936083A (titled "A Device for Stripping Cable Insulation") includes a support base, a stripping cylinder, a friction ring, a toothed ring, a screw, a gear, a telescopic rod B, a mounting block, a blade, a friction block, a telescopic rod C, a spring B, an arc-shaped block, a telescopic rod D, and a spring C. The support base is fixed to a base. The stripping cylinder, with its outer cylindrical bearing and friction ring, is fixed in a through-groove on the side of the support base. Four arc-shaped blocks are uniformly mounted circumferentially on the inner wall of the cable entry end of the stripping cylinder via telescopic rod D, which is nested with spring C. Spring C is positioned relative to the cable entry end of the stripping cylinder. The arc-shaped block is reset by its movement; four mounting blocks with blades are evenly installed circumferentially on the inner wall of the cable exit end of the stripping cylinder via telescopic rods B, and the four blades engage with the cable insulation layer located therein; four screws are threaded into four through threaded holes A evenly distributed circumferentially on the inner wall of the stripping cylinder; one end of each screw rotates in the corresponding mounting block and drives the corresponding mounting block to move axially, and the other end is equipped with a gear; the gear meshes with a gear ring installed on the friction ring; the friction block installed at the bottom of the support base via a telescopic rod C with a nested spring B engages with the friction ring.
[0004] The aforementioned cable insulation stripping equipment uses a guide mechanism and adjustable cutter structure to strip cables of different diameters. However, adjusting the blade position is cumbersome and the stability after adjustment is poor, resulting in poor accuracy in the cable insulation stripping operation. Therefore, we provide a cable insulation stripping machine. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable insulation stripping machine, comprising a support frame, a central circular frame disposed at the center of the support frame, four cutting blades disposed inside the central circular frame, and a wire core pass-through reel and a cable pass-through reel disposed at the front and rear ends of the central circular frame, respectively, wherein the diameter of the wire core pass-through reel is smaller than the diameter of the cable pass-through reel. Also includes: The movable support block is located outside the central circular frame. There are four movable support blocks, and a connecting round seat is integrally formed on the outer wall of each of the four movable support blocks. A linkage screw is movably installed inside the connecting round seat. A through screw hole is provided at the position where the linkage screw connects to the bearing frame.

A connecting rod is provided on both sides of the movable support block, and the two ends of the connecting rod are welded to the movable support block and the cutting blade, respectively. A motor carrier is located at the front end of the wire core through-reel, and a drive motor is fixedly mounted on one outer wall of the motor carrier by screws. A winding shaft is mounted on the other outer wall of the motor carrier, and the output shaft of the drive motor is connected to the winding shaft via a coupling.
[0007] Preferably, an inner disc is provided at the connection position between the linkage screw and the connecting round seat. The inner disc and the linkage screw are an integral structure. A limiting groove is provided at the connection position between the inner disc and the connecting round seat. The limiting groove and the connecting round seat are an integral structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a forward and reverse rotating nut to drive a linkage screw through a threaded hole for guided movement, thereby adjusting the displacement of the cutting blade within the central circular frame. This requires minimal manual operation, and the adjusted blade is secured by a threaded stop, ensuring high stability.

This overcomes the limitations of existing cable insulation stripping equipment, which uses a guide mechanism and adjustable blade structure to strip cables of different diameters. However, adjusting the blade position is cumbersome, and the stability after adjustment is poor, resulting in low precision in the cable insulation stripping operation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Please see Figure 1-4 An embodiment of this utility model is provided: a cable insulation stripping machine, including a support frame 1, a central circular frame 4 is provided at the center of the support frame 1, four cutting blades 18 are provided inside the central circular frame 4, and a wire core passing disc 6 and a cable passing disc 17 are respectively provided at the front end and rear end of the central circular frame 4, the diameter of the wire core passing disc 6 is smaller than the diameter of the cable passing disc 17. Also includes: The movable support block 10 is set outside the central circular frame 4. There are four movable support blocks 10, and each of the four movable support blocks 10 has a connecting round seat 11 integrally formed on its outer wall. The connecting round seat 11 has a linkage screw 13 movably set inside it. The linkage screw 13 has a through screw hole 20 at the position where it passes through the bearing frame 1. All four through screw holes 20 are integrally formed with the bearing frame 1. The connecting rod 12 is located on both sides of the movable support block 10, and the two ends of the connecting rod 12 are welded to the movable support block 10 and the cutting blade 18, respectively. The motor carrier 7 is located at the front end of the core-passing disc 6, and a drive motor 8 is fixedly mounted on one side of the outer wall of the motor carrier 7 by screws. A winding shaft 9 is mounted on the other side of the outer wall of the motor carrier 7. The output shaft of the drive motor 8 is connected to the winding shaft 9 through a coupling.
[0017] In use, the cable to be stripped is pulled in through the cable reel 17, then passes through the central frame 4, and is cut by four cutting blades 18. The cable insulation layer is stripped, and the remaining cable core passes through the core reel 6 and is finally wound onto the winding shaft 9. After stripping, the wound core is removed from the winding shaft 9. By rotating the screw cap 14 in both directions, the linkage screw 13 is guided along the screw hole 20, thereby driving the cutting blades 18 to adjust their displacement inside the central frame 4. No excessive operation is required, and the adjustment is limited by the thread, ensuring high stability. Since different cables have different insulation layer thicknesses, the position of the cutting blades 18 can be adjusted to adapt to the stripping and cutting of cables with different insulation layer thicknesses. The diameter of the core reel 6 is smaller than the diameter of the cable reel 17, so only the core can pass through the core reel 6, while the stripped cable insulation layer cannot pass through the core reel 6.
