Description

Technical Field

[0001] The utility model relates to the technical field of purification boards, in particular to a one-time forming machine for purification boards. Background Technique

[0002] The purification board is a new type of environmental protection building material, which is widely used in indoor decoration, furniture manufacturing, public place decoration and other fields. It is the main material for maintaining medical, dust-free, sterile, anti-static and other environments. Its main raw materials are wood fiber board and environmental protection resin, and it is processed through a series of production processes. The production of purification boards requires several steps such as raw material preparation, coating, drying, pressing, cutting and packaging. Among them, during the pressing and forming process of purification boards, it is necessary to apply pressure and heat to the purification boards at the same time to ensure the quality of the formed purification boards. In the prior art, during the pressing and forming process of purification boards, according to the different materials and thicknesses of the purification boards, it is necessary to adjust the forming pressure and temperature accordingly. However, some purification boards are made of multi-layer composite materials, and the heat conduction efficiency of different positions of the purification boards is different. Using traditional heating plates for direct heating will cause the temperature rise rates of different positions of the purification boards to be different, resulting in uneven temperature during the pressing process of the purification boards, affecting the pressing and forming quality of the purification boards, and the purification boards cannot be pressed and formed at one time. Subsequently, it is necessary to press the purification boards a second time. Content of the Utility Model
