Hot-pressing covering machine for facing wood lines

Abstract

A hot-pressing covering machine for facing wood lines comprises a frame, an upper mould and a lower mould, wherein the upper mould and the lower mould are oppositely arranged on the frame. The hot-pressing covering machine is characterized in that side moulds capable of reciprocating towards a molding cavity are arranged on two sides of the molding cavity between the upper mould and the lower mould respectively, a concave elastic lining is arranged in the molding cavity, and two transverse sides of the concave elastic lining are lapped on the left side mould and the right side mould respectively. After the left side mould and the right side mould are additionally arranged on the two sides of the molding cavity, a molded part is hot-pressed at one step by means of sequentially closing the upper mould, the left side mould and the right side mould, particularly, a blank is hot-pressed in the molding cavity by the aid of the concave elastic lining, and a facing sheet cannot crease or crack or be pierced.

Description

【Technical field】 [0001] The invention belongs to a veneer wood molding hot-pressing coating machine. 【Background technique】 [0002] With the continuous improvement of people's living standards, the application of decorative moldings is also becoming more and more extensive. The so-called veneer molding is a product formed by using low-grade wood, such as Chinese fir, as the core material, and then covering the outer contour of the core material with a layer of high-grade precious wood flakes. This product solves the problems of high cost, waste of resources, and the differences in wood grain and color of high-grade precious wood to make wooden moldings, and satisfies people's desire to obtain the best decorative effect at the lowest price. [0003] At present, there are usually two methods for making veneer moldings, namely: high-grade and low-grade wood are first compounded and then made, or made first and then pasted and compounded. The latter usually has the following...

AI Technical Summary

Problems solved by technology

In actual operation, the above two methods have corresponding problems: when the hot pressing process is used, because the veneer sheet is very thin, wrinkling and cracking often occur. , time-consuming and labor-intensive, low efficiency, and poor product consistency, low pass rate

When rolling forming is used, since the hot pressing temperature of the molded parts cannot be maintained for a long time like molding, the requirements for glue are very high. In practice, only expensive hot melt can be used, which leads to a significant increase in production costs. In addition, due to the influence of particles on the surface of the core material, the veneer sheet is often punctured and there are holes in the core material; it is difficult to complete the processing of some wood moldings with special-shaped concave-convex finishes
