Description

Technical Field

[0001] The utility model relates to the technical field of automatic cable stripping and crushing, in particular to an automatic cable stripping and crushing device. Background Art

[0002] Most of the current cable stripping devices are purely manual. When in use, the blade is inserted into the blade hole, and the position of the blade is adjusted by the blade adjuster to adapt to the depth of cutting the cable sheath. The cable to be cut is then straightened and placed in the cable slot of the stripping tool with the blade adjusted. The buckle is fastened to prevent the tool from automatically opening during use. One person holds the two handles of the stripping tool with both hands, and the other person pulls the cable to be stripped tightly at the other end. The two people apply force in opposite directions at the same time to achieve the effect of stripping the cable sheath of the cable.

[0003] The existing Chinese utility model with publication number CN220086832U discloses an automatic cable stripping device, including a stripping device, which includes a chassis with a driving motor installed inside and a guide wheel installed at one end of the chassis. The guide wheel is rotatably connected to the chassis, and a wire groove is provided on the surface of the guide wheel along the radial direction. A cutting blade is installed in the wire groove. A handle is installed on the outer wall of the chassis perpendicular to the axial direction of the chassis, and a control key for controlling the opening and closing of the driving motor is provided below the handle. The device is suitable for cable stripping. When using the automatic stripping device to strip the cable, the operator only needs to hold the handle and then cut the cable through the cooperation of the guide wheel and the cutting blade. The operation is simple and one person can complete the cable stripping operation, which greatly saves the labor intensity of the operator, shortens the operation time, and improves the work efficiency of stripping.

[0004] However, these tools are only suitable for cables of specific sizes and cannot be used for all different cables. They cannot be replaced with different blades for cutting and stripping different cables. Furthermore, they require an external shredder to shred the cables after stripping, which is time-consuming, labor-intensive, and extremely inconvenient. Therefore, we have developed an automatic cable stripping and shredding device to address these issues. Utility Model Content
