Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of plate forming, and in particular to an integrated plate forming system. Background Art
[0002] At present, there are two main forms of fiber cement board and fiber cement tile industry in China: the slurry forming method and the slurry flowing method. Among them, the slurry forming method is a production process that uses the internal and external pressure difference of the rotating mesh wheel in the mesh box to filter the slurry suspension, form a primary material layer on the mesh wheel and transfer it to the felt cloth, dehydrate it and continuously wind it on the forming cylinder to compact it to obtain the blank; the slurry forming method has a large production capacity and produces a flat board surface, but it cannot be used to produce high-end boards such as full-color boards. The slurry flowing method is a production process that uses a slurry box to evenly spread the slurry suspension on the running felt cloth to form a continuous slurry layer, dehydrate it and continuously wind it on the forming cylinder to compact it to obtain the blank; the slurry flowing method production line can produce all types of boards, but the flatness of the board surface is lower than that of the slurry forming method.
[0003] In summary, the existing paper-cutting forming machines cannot be used to produce high-end panels such as full-body panels. The panels produced by the existing flow slurry forming machines have relatively poor surface flatness, poor strength with the same formula, and low output. If the factory needs to produce different categories of products or expand production capacity, it needs to add new paper-cutting production lines or flow slurry production lines, which requires a larger factory area and more equipment costs.
