Description

Technical Field

[0001] The utility model belongs to the technical field of wire stripping machines and relates to a wire stripping machine. Background Art

[0002] The plastic insulation layer of waste wires and the conductive copper wire wrapped in it have great recycling value. The most primitive method of separating the plastic insulation layer and the copper wire of waste wires is to peel off the insulation layer little by little with a utility knife. This method has low stripping efficiency and there is a problem that the utility knife may scratch the operator.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent literature discloses a frame of a wire stripping machine [patent number: 202223022196.3; application publication number: CN218730155U]. The frame of the wire stripping machine is integrally formed by injection molding or casting. The frame includes a bottom plate, a top plate and two side plates. The bottoms of the two side plates are fixedly connected to the bottom plate, and the tops of the two side plates are fixedly connected to the top plate. The lower part of the side plate has a through hole for the rotating shaft to pass through.

[0004] The wire stripping machine of this structure has a locking hole arranged in the horizontal direction and a guide groove arranged in the vertical direction in the frame. The tool is installed in the tool holder. The tool holder has an adjustment hole in the shape of a long strip and arranged in the vertical direction. The tool holder is partially embedded in the guide groove and can move along the guide groove. The tool holder is fixedly connected to the top plate by fasteners passing through the adjustment hole and the locking hole. When adjusting the height of the tool, it is necessary to loosen the fasteners and then move the tool holder up and down along the guide groove. After the tool moves into place, the operator presses the tool holder on the frame and then tightens the fasteners. In the process of tightening the fasteners, the operator may not press the tool holder tightly, causing the tool to move downward or upward by a certain distance, resulting in the tool position not being adjusted in place and needing to be readjusted, which is troublesome to adjust the height of the tool. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art, proposes a wire stripping machine, and solves the technical problem of how to make the cutter of the wire stripping machine convenient to adjust and the cutter adjustment precision high.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a wire stripping machine, comprising a frame and a knife seat for installing a knife, characterized in that it also includes an adjusting rod, the frame comprises at least two guide rods arranged in a vertical direction, the two ends of the knife seat are respectively sleeved on the corresponding guide rods, the adjusting rod is passed through the top of the frame, the adjusting rod and the frame are threadedly connected, the bottom of the adjusting rod is axially positioned and circumferentially rotatably connected to the knife seat, and rotating the adjusting rod can make the knife seat move up and down along the guide rod.

[0007] When adjusting the wire stripping machine, you only need to rotate the adjustment rod. Rotating the adjustment rod can make the knife seat move up and down along the guide rod, so that the height of the knife can be adjusted, making the knife of the wire stripping machine easy to adjust. The adjustment rod and the frame are threadedly connected. Stop rotating the adjustment rod to position the adjustment rod, and the position of the knife seat can be positioned. The knife seat does not have the problem of moving up and down, which improves the adjustment accuracy of the knife.

[0008] In the above-mentioned wire stripping machine, the frame also includes a base and a top plate, the base is fixedly connected to the top plate through the guide rod, the adjustment rod passes through the top plate, and the adjustment rod is threadedly connected to the top plate. This structure connects the base and the top plate through the guide rod to form a whole, so that the guide rod is also a part of the frame structure, which has a reasonable design and a compact structure.

[0009] In the above-mentioned wire stripping machine, the bottom of the guide rod is fixedly connected to the top of the base by means of threads, and the top of the guide rod is fixedly connected to the top plate by fasteners. This structure makes the frame assembly convenient, and the fasteners are bolts.

[0010] In the above-mentioned wire stripping machine, the adjusting rod is externally threaded with a locking nut, and the locking nut can abut against the top plate. After the knife seat is adjusted, the locking nut is rotated to abut against the top plate, which can lock the adjusting rod so that the adjusting rod will not move, thereby fixing the knife seat and improving stability.

[0011] In the above-mentioned wire stripping machine, the top of the adjusting rod has a gripping part protruding toward the surroundings. The setting of the gripping part makes the adjusting rod easy to rotate and saves effort.

[0012] In the above-mentioned wire stripping machine, the left and right ends of the knife seat have guide holes, the guide rod passes through the guide hole, and the guide rod is matched with the hole wall of the guide hole. The guide rod and the guide hole match each other, so that the knife seat moves smoothly, the movement accuracy of the knife seat is improved, and thus the adjustment accuracy of the tool is improved.

[0013] In the above-mentioned wire stripping machine, the middle of the bottom of the knife seat has a mounting portion protruding downward, and the knife is mounted in the mounting portion. This structure makes the overall volume of the knife seat smaller and makes the structure of the wire stripping machine more reasonable.

[0014] In the above-mentioned wire stripping machine, the base is provided with a receiving groove, a rotatable positioning wheel is installed in the receiving groove, and a ring-shaped wire passing groove is provided in the middle of the circumference of the positioning wheel.

[0015] Compared with the prior art, the wire stripping machine provided by the utility model has the following advantages:

[0016] 1. When adjusting the wire stripping machine, you only need to rotate the adjustment rod. Rotating the adjustment rod can make the knife seat move up and down along the guide rod, so that the height of the knife can be adjusted, making the knife of the wire stripping machine easy to adjust.

[0017] 2. The adjusting rod of the wire stripping machine is threadedly connected to the frame. Stop rotating the adjusting rod to position the adjusting rod, and the position of the knife seat can be positioned. The knife seat does not move up and down, which improves the adjustment accuracy of the knife. BRIEF DESCRIPTION OF THE DRAWINGS
