[0001] This utility model relates to the field of wire stripping machine technology, specifically a wire stripping machine. Background Technology

[0002] To protect the ecological environment, environmental protection is currently the development direction of industrial production. Among these, the recycling of old materials is a crucial part of achieving environmental protection. Wires or cables consist of an internal core and an insulation layer surrounding the core. Because the core and insulation are made of different materials, recycling wires or cables requires stripping the insulation layer. The stripped insulation and core are then sorted and recycled separately.

[0003] However, existing wire stripping machines are not designed with baffles, making it easy for operators to accidentally entangle other items along with the cables into the machine during operation. This reduces the lifespan of the stripping blades and affects the quality of cable stripping. Summary of the Invention

[0004] The purpose of this utility model is to provide a wire stripping machine to solve the problem mentioned in the background art that the existing wire stripping machines are not designed with baffles, which makes it easy for operators to get other items besides the wires into the wire stripping machine along with the wires during operation, thereby reducing the service life of the cutting blades of the wire stripping machine and affecting the quality of wire stripping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire stripping machine, including a base, a frame fixedly installed on the top of the base, a first shaft and a second shaft rotatably connected inside the frame, the first shaft being located directly below the second shaft, the first shaft and the second shaft being meshed together, a first baffle being fixedly installed on the front surface of the frame at the relative position of the first shaft and the second shaft by fasteners, a plurality of wire inlet holes being opened on the surface of the first baffle at the relative position of the connection between the first shaft and the second shaft, and a second baffle being rotatably fitted on the rear surface of the frame by a fixing block.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-4This is a schematic diagram of a wire stripping machine according to a preferred embodiment of the present invention. In this embodiment, the wire stripping machine includes a base 1, which serves as an integral support structure. A frame 2 is fixedly mounted on the top of the base 1 by bolts. A first shaft 3 and a second shaft 4 are rotatably connected inside the frame 2. The first shaft 3 is located directly below the second shaft 4, and the first shaft 3 and the second shaft 4 are meshed together. The two shafts rotate synchronously through gear meshing. Specifically, a first gear 31 is fixedly mounted on the same side of the first shaft 3, and a second gear 41 is fixedly mounted on the same side of the second shaft 4. The first gear 31 and the second gear 41 are meshed together. A first baffle 5 is fixedly mounted on the front surface of the frame 2 at the position opposite to the first shaft 3 and the second shaft 4 by fasteners. The surface of the first baffle 5, facing the meshing contact area of ​​the first shaft 3 and the second shaft 4, has multiple wire inlet holes 51 of different diameters. At least one fixing block 21 is fixedly mounted on the rear surface of the frame 2. The surface of the fixing block 21 has a rotating hole 211. A rotating rod 61 is fixedly connected to the surface of the second baffle 6 at a position corresponding to the rotating hole 211. The rotating rod 61 is inserted into the rotating hole 211 and can rotate relative to it, thereby realizing the rotational engagement between the second baffle 6 and the rear end of the frame 2.

[0029] In this embodiment, a conversion element 7 is fixedly installed on the top of the base 1, at the left end of the frame 2. The conversion element contains a helical gear. A drive motor 8 is mounted on the top of the conversion element 7. The helical gear connected to the output shaft of the drive motor 8 meshes with the helical gear of the conversion element 7. Simultaneously, the right end of the first shaft 3 passes through the right side wall of the frame 2 and connects to the helical gear of the conversion element 7, thereby receiving power from the drive motor 8. The left end of the second shaft 4 passes through the left side wall of the frame 2 and is fixedly connected to an operating handle 27, facilitating manual operation or manual rotation in emergencies.

[0030] In this embodiment, the outer circumferential surface of the first shaft 3 is uniformly provided with various stripping grooves 32 of different widths along the axial direction, which is intended to accommodate cables of different diameters. On the outer circumferential surface of the second shaft 4, cutting blades 42 of various specifications are fitted and fixed at positions corresponding to the various stripping grooves 32. The opening size of the multiple inlet holes 51 is designed to match the width of the various stripping grooves 32, ensuring that wires of different diameters can enter the corresponding stripping groove 32 area for processing through the matching inlet holes 51.

[0031] In this embodiment, vertical adjustment positions 22 are provided at both ends of the surface of the frame 2. An adjustment block 23 that can slide up and down is movably connected within each adjustment position 22. The journals at both ends of a second shaft 4 are rotatably connected between two adjustment blocks 23 via bearings, allowing the second shaft 4 to move up and down with the adjustment blocks 23. Simultaneously, a connecting nut 24 is fixedly connected to the top of each adjustment block 23 at the top of the frame 2. The lower part of the adjustment handle 25 is a screw, and the screw portion of the adjustment handle 25 is threaded into the connecting nut 24. The bottom of the adjustment handle 25 is rotatably connected to the top of the adjustment block 23 via a bearing. A spring 26 is sleeved on the screw portion of the adjustment handle 25. The top of the spring 26 abuts against the inner surface of the top of the adjustment position 22, and the bottom of the spring 26 abuts against the top surface of the adjustment block 23. This provides an upward preload from the spring 26, keeping the adjustment block 23 and the second shaft 4 in a reference position when there is no external force. When it is necessary to adjust the clearance between the second shaft 4 and the first shaft 3, rotate the adjusting handle 25. Clockwise rotation pushes the adjusting block 23 downwards against the spring force, reducing the clearance between the blade and the stripping groove to increase the cutting depth of the cable. Counterclockwise rotation pushes the adjusting block 23 upwards, increasing the clearance to reduce the cutting depth. After adjustment, the preload of the spring 26 helps maintain the stability of the adjusted position.

[0032] Working principle

[0033] Based on the diameter of the conductor to be stripped, select the matching inlet hole 51 on the first baffle 5. By rotating the adjusting handles 25 at both ends, precisely adjust the gap between the cutting blade 42 on the second shaft 4 and the corresponding stripping groove 32 on the first shaft 3 to ensure that the insulation layer can be cut without damaging the conductor. Insert one end of the conductor to be stripped through the selected inlet hole 51, so that it is embedded in the corresponding stripping groove 32 on the first shaft 3, and start the drive motor 8. The drive motor 8 drives the first shaft 3 to rotate through the conversion component 7. The first shaft 3 drives the second shaft 4 to rotate in the opposite direction through the meshing first gear 31 and second gear 41. The rotating first shaft 3 clamps the cable through the stripping groove 32 and pulls it backward. At the same time, the reverse rotating second shaft 4 drives the cutting blade 42 to cut the insulation layer of the conductor at a set depth. The conductor continues to move backward, and the cut insulation layer is stripped off. The stripped conductor is sent out from between the first shaft 3 and the second shaft 4 at the rear end of the frame 2. When the stripped cable is sent out, the stripped cable head rests against the inner wall of the second baffle 6, causing the rotatable second baffle 6 to flip outward and upward, serving as a guide and protection. When it is necessary to clean the internal wire debris or maintain the blades, the second baffle 6 can be manually rotated around the rotating rod 61 to flip outward and upward, easily exposing the working area inside the frame 2.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
