Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of acrylic plate production, and particularly relates to a laser cutting device for acrylic plate production. BACKGROUND

[0002] Acrylic plate production is a high-transparency plastic plate material made of polymethyl methacrylate monomer or prepolymer through casting, extrusion or injection molding process. In the production process, first, raw materials are prepared by adding plasticizers and color masterbatch and other additives, and then the plate material is formed through polymerization reaction. The casting method uses a mold for slow polymerization, and the extrusion method uses a screw for melt extrusion molding. The molded plate material is subjected to temperature control and solidification to eliminate internal stress, and then subjected to cutting, polishing and film coating and other post-processing procedures. The finished product has a light transmittance of more than 92%, excellent weather resistance and mechanical strength, and is mainly used in the fields of advertising signs, building lighting and furniture decoration. Modern production processes combine digital processing technologies such as laser cutting and numerical control engraving to realize high-precision customized production, and waste gas recovery and waste regeneration technologies are used to reduce the impact on the environment.

The rotational movement of the reciprocating screw rod is converted into the axial displacement of the screw cap, and then the whole of the connecting rod, the support plate and the anti-skid plate are driven to move through the guiding action of the moving plate and the slide rod. In this process, the friction between the anti-skid plate and the acrylic plate body drives the plate material to slide smoothly on the receiving plate and the moving plate, and the axial movement accuracy is ensured by the clamping plate, so as to accurately transport the area to be processed to the processing position of the laser cutting assembly.

[0031] 2. In the present application, when the anti-skid plate is reset and moved, the fixed shaft drives the rotating ring and the movable rod to move cooperatively. The movable rod forms a lever action through the pin shaft in the connecting frame, and its upward movement is converted into the downward displacement of the other side. This mechanical linkage further drives the telescopic rod to drive the cylinder and the mounting rod to move along the sliding groove, so as to finally drive the pressing block to drive the pressing plate to complete the pressing action. When the anti-skid plate is completely reset, the pressing plate and the clamping plate form a cooperative clamping force to ensure the stability of the acrylic plate body during the processing process, effectively inhibiting the displacement risk caused by processing vibration. This design realizes the automatic connection of the plate positioning and clamping action, and significantly improves the processing accuracy and operation efficiency. BRIEF DESCRIPTION OF DRAWINGS
