Plate cutting device

Abstract

The invention relates to the field of plate processing, and particularly discloses a plate cutting device. The plate cutting device comprises a cutting mechanism and a moving mechanism. The cutting mechanism comprises a fixed block and two cutting units. Each cutting unit comprises a sliding block, a stay cord, a circular-arc-shaped elastic cutting knife and an electric heat wire, and the outer circles of the elastic cutting knives are wrapped with the electric heat wires. The fixed block is welded to on the upper portion of a conveying belt. The lower surface of the fixed block is provided with a sliding surface for allowing the sliding blocks to slide. A sliding groove is formed in the central line of the sliding surface. The bending directions of the elastic cutting knives in the two cutting units are opposite. The two elastic cutting knives are vertically arranged. The upper ends of the elastic cutting knives and the sliding blocks are welded. The lower ends of the sliding blocks and one ends of the stay cords rare welded. The inner circles of the elastic cutting knives are provided with friction strips. Knife edges of the elastic cutting knives are located on the two sides ofthe elastic cutting knives. According to the scheme, a plastic plate can be cut and subjected to chamfering simultaneously, the processing work procedure of the plastic plate is reduced, and the processing efficiency of the plastic plate is improved.

Description

technical field [0001] The invention belongs to the field of plate processing, and in particular relates to a plate cutting device. Background technique [0002] Plastic sheet is a commonly used manufacturing material in household electrical appliances. In the conventional processing of plastics, it is often necessary to cut the sheet-shaped plastic. Because plastic products have a certain hardness, when cutting, the cutting section of the plastic sheet will be There are many scratches or burrs. [0003] Therefore, in the cutting of plastic boards, the section of the plastic board is generally trimmed manually. The trimming rate of the cross-section is inconsistent during manual operation, the processing accuracy is low, not flexible enough, and the production efficiency is also reduced; and in the plastic board cutting process It is easy to generate splashes of plastic debris, pollute the environment, and lead to a large waste of plastic materials. Sometimes after cutting...

[0003] Therefore, in the cutting of plastic boards, the section of the plastic board is generally trimmed manually. The trimming rate of the cross-section is inconsistent during manual operation, the processing accuracy is low, not flexible enough, and the production efficiency is also reduced; and in the plastic board cutting process It is easy to generate splashes of plastic debris, pollute the environment, and lead to a large waste of plastic materials

Sometimes after cutting the plastic board, there is also the work of rounding the cross-section of the plastic board. Generally, the cutting and chamfering of the plastic board are separated, but this will increase the processing of the plastic board. At the same time, it is necessary to fix the same plastic plate multiple times, and the operation is complicated
