Fiber slurry synchronous-adsorption molding lamination composite forming process method and forming machine thereof

Abstract

The invention provides a fiber slurry synchronous-adsorption molding lamination composite forming process method. According to the fiber slurry synchronous-adsorption molding lamination composite forming process method, main molding work positions are arranged in a stepping rotation way, and adsorption and molding are conducted in a stepping interval to form first-layer wet blanks; auxiliary molding work positions are arranged in the rotation path of the main molding work positions, auxiliary wet blank combined molds formed by adsorption and molding at the auxiliary molding work positions aretransferred and stacked on the wet blanks at the main molding work positions, and then mold combination and unloading are carried out at unloading work positions of stepping tail ends. The invention also provides a forming machine for implementing the process method. The forming machine has the technical advantages of being simple in machine structure, simplified in process and high in automationdegree and efficiency.

Problems solved by technology

And with the development of various fields, its development and application prospects are increasingly broad, and the performance requirements of its molded products are also more diverse and in-depth, such as the surface properties of the products, the overall strength of the products, hardness, thickness, and inner parts of the products. The technical requirements for various aspects such as texture, function and color diversification of layer, middle layer, etc. are also increasing day by day. It is necessary to absorb, transport, re-adsorb, and then transport to the forming process from the existing layer-by-layer sequence to different slurry pools. Technical process methods are obviously difficult to meet these technical requirements. There are complex molding processes, long production lines, and low production efficiency. In addition, the technical difficulty of adapting and transforming the production line according to these technical requirements can also be imagined. The cycle of deployment and design is long, the cost of product conversion design is high, and it is impossible to meet the conversion and manufacturing needs of products with different performances by one set of equipment
