Background

The high-pressure resin laminated board is also called HPL (High Pressure Laminates), HPL is a thermosetting sheet prepared by respectively impregnating melamine resin adhesive and phenolic resin adhesive with a plurality of special papers, stacking different types of impregnated special papers according to the technological requirements such as product thickness and the like, and carrying out hot pressing. The high-pressure resin laminated board not only has excellent service performance and decorative effect such as heat resistance, fire resistance, water resistance, corrosion resistance, wear resistance and the like, but also has higher added value, expands the service range of the artificial board and improves the use of the artificial board.

The high-pressure resin laminated board is usually manufactured by hot pressing by a high-pressure method, a multi-layer press is usually adopted as a hot pressing device for producing the high-pressure resin laminated board, a cold-hot-cold process is usually adopted for pressing, and saturated steam or superheated water can be adopted as a heating medium, but the superheated water is the most ideal. Since the consumption of both heat energy and cooling water is large in the process of periodically alternating heating and cooling, the production cost of the high-pressure resin laminate is high.

The material for pressing the high-pressure resin laminated board comprises surface paper, decorative paper, bottom paper and demolding paper, wherein the surface paper, the decorative paper and the covering paper are impregnated with melamine resin adhesive, the bottom paper is impregnated with phenolic resin adhesive, and the demolding paper is impregnated with phenolic resin adhesive added with oleic acid. Before hot pressing, various impregnated papers are assembled according to the thickness required by the specification of the product. In general, in one sheet blank, the top sheet, the decorative sheet, the cover sheet, and the release sheet are each one sheet, and the number of the bottom sheet is appropriately increased or decreased according to the thickness of the high-pressure resin laminate sheet to be produced. In the actual production process, in order to improve the efficiency and the yield of the press, 10-14 high-pressure resin laminated board slabs are usually put into each layer of the press, and each slab has two combination modes in each layer of the press.

Meanwhile, in order to obtain good surface gloss of the high-pressure resin laminated board, the press adopts a cold-hot-cold hot pressing process, if steam or gas exists in the board blank, volatile matters formed by heating the steam or the gas can be suddenly expanded in volume and can escape outwards in the process of depressurization of the press, a plurality of tiny bubbles are formed on the surface layer, and the surface gloss of the high-pressure resin laminated board can be greatly reduced, so that the quality of a product is influenced.

The conventional automatic transfer and conveying device for high-pressure resin laminated board production can uniformly stack various impregnated papers after the impregnation and conveying are completed in a press, but can not directly transfer different impregnated papers from different processing stations. The conveying device is still required to be arranged between each impregnated paper processing station and the automatic transferring and conveying device for conveying the impregnated paper, so that the conveying cost for producing the high-pressure resin laminated board is increased, and the conveying efficiency is not improved. In the stacking process of the impregnated paper, a certain gap is inevitably formed between the impregnated paper and the impregnated paper, and gas or steam entering the gap can form volatile matters in the plate blank in the pressurizing process of the press and outwards escape in the subsequent depressurization process, so that the surface glossiness of the high-pressure resin laminated plate is finally affected.
