PVC foaming plate surface laminating device and method

Abstract

The invention discloses a PVC foaming plate surface laminating device and method, and relates to the technical field of PVC foaming plate production. The device comprises a set of first supporting plates, a pipe body, a pressing plate and a thin film. Second supporting plates are fixed to one surfaces of the first supporting plates, third supporting plates are fixed to the other surfaces of the first supporting plates, thin film rollers are mounted on the two second supporting plates, a driven roller is connected between the two first supporting plates through a bearing, baffles are fixed to the two ends of the pipe body, and one baffle is rotationally connected with one surface of one first supporting plate through a rotary shaft and a bearing. Multiple grooves are formed in the pipe body, multiple air outflow pipes communicating with the interior of the pipe body are arranged on the inner walls of the grooves, after a first air blower feeds external air into the pipe body, the air can be exhausted along the multiple air outflow pipes, thus, the thin film on the pipe body can be fully flattened under dual effects of the grooves and airflow, the laminating effect of a PVC foaming plate is better, and the quality is higher.

Description

technical field [0001] The invention belongs to the technical field of PVC foam board production, and in particular relates to a PVC foam board surface coating device and a coating method. Background technique [0002] PVC foam board is also called Chevron board and Andy board, and its chemical composition is polyvinyl chloride, so it is also called foamed polyvinyl chloride board. Widely used in passenger cars, train car ceilings, box core layers, interior decoration panels, building exterior wall panels, interior decoration panels, offices, residences, building compartments in public places, etc. In the actual transportation and sales of PVC foam boards, the surface is often covered with a film to protect the surface of the PVC foam board from being easily damaged during transportation and handling, so that the PVC foam board can be used in the subsequent The effect is better in use and sale. [0003] The existing PVC foam board surface coating device is not easy to effe...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a PVC foam board surface coating device and coating method, by opening a number of grooves on the pipe body, and setting a number of air outlet pipes connected with the inside of the pipe body on the inner wall of the groove, After the first blower sends the outside air into the pipe body, it can be discharged along several air outlet pipes, so that the film on the pipe body can be fully flattened under the double action of the groove and the air flow, which solves the problem of existing PVC The film coating device on the surface of the foam board is not easy to flatten the film, which makes the film coating effect of the PVC foam board poor and the error is large, which affects the later protection, transportation and sales of the PVC foam board
