Preparation method of composite floor

Abstract

The invention relates to the technical field of composite floors, and discloses a preparation method of a composite floor, the composite floor and a laminating machine. The method comprises the steps that the laminating machine is used for conducting primary glue injection and primary hot pressing on a base board and a bearing frame, and secondary glue injection and secondary hot pressing are carried out on an upper surface board and the bearing frame by using the laminating machine; and the laminating machine is used for conducting three-time glue injection on the glue injection hole of a supporting part and conducting three-time hot pressing, the upper surface board, the base board, the bearing frame and the supporting part are laminated into the composite floor, and the laminating machine is matched with a glue injection mechanism of the laminating machine, so that on one hand, automatic control of the glue injection process is achieved; and on the other hand, the injected glue has certain pressure, so that the injected glue can fully fill the glue injection space, the glue is distributed more uniformly, and in the hot-pressing laminating process, the bonding strength can be improved, and the hot-pressing laminating quality of the composite floor is improved.

Description

technical field [0001] The invention relates to the technical field of composite floors, in particular to a preparation method for composite floors, a composite floor and a composite machine. Background technique [0002] Composite flooring is generally made of multi-layer veneers pressed and compounded by a composite machine. Because the physical structure of composite flooring is different from that of logs, it overcomes the weakness of poor stability of logs. In high-end decoration places such as homes and offices, it has gradually become a high-end decoration material. [0003] In the pressing and compounding process of laminated flooring, a compounding machine is often used to compress and compound the multi-layer veneers injected with glue. In the Chinese invention patent with application number 201911108538.3, a floor cold-pressing compounding process and a floor cold-pressing machine are disclosed. , by adjusting the length of the output shaft of the first cylinder,...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a preparation method of a composite floor, a composite floor and a composite machine, so as to solve the problem of pressing the composite floor in the above-mentioned background technology. Often there is poor cooperation with the glue injection mechanism, resulting in excessive glue injection, and the excess glue is squeezed out during extrusion and compounding, causing the excess glue to be polluted and wasted; secondly, too little glue injection will easily affect the composite floor. The adhesive strength of the colloid is too low, resulting in the quality of the composite floor not up to the standard; thirdly, the use of the blower to cooperate with the glue injection process will easily lead to premature curing of the glue, which will affect the bonding strength of the colloid, resulting in the technical problem that the quality of the composite floor is not up to standard
