Description

TECHNICAL FIELD

[0001] The utility model relates to the field of veneer production technology, especially to a high-temperature laminating equipment for self-adhesive PVC veneer production. BACKGROUND

[0002] The high-temperature laminating equipment for self-adhesive PVC veneer production plays a crucial role in the industry. It uses high temperature to tightly bond the PVC film with the substrate, ensuring product quality and appearance effect. The working principle of the high-temperature laminating equipment is mainly based on the hot-pressing composite process. This process heats the laminating roller or heating plate to a certain temperature through a heating system, and then sends the PVC film and substrate to be laminated into the equipment. Under the combined action of pressure and heat, the glue or hot melt adhesive between the PVC film and the substrate melts, achieving tight lamination. Subsequently, the cooling system cools and shapes the composite material to ensure firm lamination.

[0003] The existing paper pressing device adopts a structure of upper and lower parallel distribution of pressing rollers to press and bond different layers of veneer paper, achieving the pressing effect of the veneer paper. When the veneer paper is conveyed forward into the pressing structure, the veneer paper will span a certain length. When the veneer paper spans a long distance, the veneer paper will relax, resulting in insufficient tension of the veneer paper, and thus unable to perform subsequent efficient pressing treatment.

[0004] The existing patent (publication number: CN220262303U) discloses a decoration printing veneer pressing device, which includes a pressing table provided with a pressing frame. It uses an adjusting piece to control the upper and lower tensioning rollers, which can synchronously and reversely adjust the height position of the upper and lower tensioning rollers, so that the upper and lower tensioning rollers can respectively adjust and control the tension of the veneer to be pressed, ensuring that the veneer can maintain stable and appropriate tension when entering the pressing structure for pressing treatment.

[0005] To solve the above problems, the existing patent uses an adjusting piece to control the upper and lower tensioning rollers, ensuring that the veneer can maintain stable and appropriate tension when entering the pressing structure for pressing treatment. However, it is not convenient to cool the workpiece after pressing, and the workpiece has residual heat on the surface after pressing, and the workpiece itself cools slowly, affecting subsequent processing.
