A2-grade fireproof metal film-coated decorative plate production line and production process thereof

Abstract

The invention discloses an A2-grade fireproof metal film-coated decorative plate production line and a production process thereof. The A2-grade fireproof metal film-coated decorative plate productionline comprises an outer shell, a conveying device, a heating box, an unwinding device, a guide wheel set, a tensioning device, a film pressing device, a winding roller, a pressing device and a clamping device. The swing frame of the tensioning device swings left and right, and a decorative film can be in a tensioned state all the time, therefore, ripples are prevented from being formed after the decorative film is pressed on the plate; the unwinding device is provided with a plurality of groups of unwinding rollers, various decorative film winding drums with different widths can be installed,film replacement is more convenient, the clamping device can adjust the clamping distance according to plates with different widths, the plates can be guided and prevented from deviating, and in the production process, the plates are heated in advance, so that the peeling strength of the plates can be guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of decorative board coating, in particular to an A2 grade fireproof metal coated decorative board production line and a production process thereof. Background technique [0002] Decorative boards are widely used in the installation of indoor and outdoor walls. In order to increase the aesthetic effect of the decorative surface, a layer of PVC decorative film is applied on the surface of the decorative board. Traditional film-coated decorative panels generally use manual filming or extremely simple equipment for filming. Due to human factors, the process of filming cannot be kept consistent, and the decorative film is easy to deviate, which eventually leads to product quality. In addition, due to the traditional simple rolling film press (including the steel roller set in the front and the rubber roller set in the rear) during lamination, the substrate travels between the two steel rollers and then passes thr...

AI Technical Summary

Problems solved by technology

Traditional film-coated decorative panels generally use manual filming or extremely simple equipment for filming. Due to human factors, the process of filming cannot be consistent, and the decorative film is easy to deviate, which eventually leads to product quality.

In addition, due to the traditional simple rolling film press (including the steel roller set in the front and the rubber roller set in the rear) during lamination, the substrate travels between the two steel rollers and then passes through the rubber roller set. After passing through the upper and lower rubber rollers, air bubbles remain between the substrate and the decorative film, which eventually leads to orange peel and uneven ripples in the product, and the quality of the final product cannot be guaranteed.

Furthermore, because both the surface of the board and the decorative film are in a cool state, the combination of the two will make it difficult for the peel strength of the board to meet the standard requirements.

Therefore, the traditional processing method of film-coated decorative panels has the hidden dangers of low production efficiency and unguaranteed product quality.
