Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting of rubber and plastic foaming materials, and particularly relates to an edge trimming processing device and a processing technology for rubber and plastic foaming materials. Background Art

[0002] Rubber and plastic foaming materials (such as EPDM, NBR, PVC, EVA, etc.) are widely used in the fields of automotive seals, building shock-absorbing materials, electronic equipment cushions, sports equipment, and packaging due to their light weight, high elasticity, heat insulation, sound absorption, and chemical corrosion resistance. During the manufacturing process, rubber and plastic foaming materials are usually molded into blanks with specific shapes by compression molding, extrusion, or injection molding. Subsequently, edge trimming processing is required to remove excess edge materials to obtain finished products with precise dimensions and smooth edges. Therefore, edge trimming processing equipment for rubber and plastic foaming materials is needed.

[0003] Existing edge trimming processing equipment for rubber and plastic foaming materials mainly includes tool cutting or mechanical cutting. Tool cutting relying on manual operation has large influence on processing accuracy by the operator's experience, poor consistency, and potential safety hazards, and it is difficult to meet the requirements of mass production. Most existing automated mechanical cutting equipment is designed for hard materials and has poor adaptability to soft and easily deformable rubber and plastic foaming materials. During the edge trimming process, size deviation or edge burrs are easily caused due to material compression and deformation.

[0004] Therefore, in order to improve the edge trimming accuracy, a thermal cutting process, such as laser cutting, is also adopted in the market. For example, a Chinese patent document with the authorized publication number CN113547235B discloses an automatic cutting equipment for rubber and plastic products, which records that "including a cutting table, a first gear belt, and a second gear belt, a left support table is arranged at one end of the cutting table, a right support table is arranged at the other end of the cutting table, and support tables are respectively arranged on both sides at one end of the cutting table". This device can realize the function of automatically separating the cut material from the waste rubber and plastic board, improving the convenience of the automatic cutting equipment for rubber and plastic products.

[0005] However, most existing laser edge trimming equipment places rubber and plastic foaming materials on the workbench. When using a laser cutting device to perform edge trimming on rubber and plastic foaming materials, the high temperature generated by the laser cutting device easily causes the edge trimming surface of the rubber and plastic foaming materials to melt and carbonize. Some residues of the melted and carbonized part are likely to drip onto the workbench, causing the surface of the workbench to be uneven, thereby affecting the subsequent edge trimming of rubber and plastic foaming materials. Therefore, the workbench needs to be frequently cleaned during use, which affects work efficiency. In addition, the direct action of the laser cutting device on the surface of the workbench is also likely to damage the surface of the workbench. For this reason, we have developed an edge trimming processing device and a processing technology for rubber and plastic foaming materials. Summary of the Invention
