Abstract

The invention discloses a process for integrally molding wood veneers by laminating and calendering techniques. The key points of the technical scheme include the following steps: a. Piecing the skins: seamlessly splicing the veneers into pieces longitudinally or horizontally to ensure the width of the veneers. Maximize the width of the veneer, and at the same time modify the transparent texture on the surface of the veneer, and fill it with the same wood grain color to ensure that the overall appearance of the thin veneer is uniform and solid, and there is no abnormal bottoming; b. Extrusion casting: one of the plastic raw materials with different properties Or several kinds of mixtures are put into the extruder hopper, through heating, kneading, plasticizing, extruding, extruding and casting on the laminating machine to form a film, extruding and casting on the laminating machine to form a film, and adjust the film to the required The thickness and deviation of the thickness and deviation; c, laminating film pressing: on the adjusted casting film, the spliced ​​veneer and high temperature resistant base film are introduced into the calendering roller group for multi-roller pressing; d, cooling forming: after pressing The veneer is cooled, trimmed, and rolled into coils through a winder.

Description

[Technical field] [0001] The present invention belongs to the field of wood processing, and more particularly to an integral forming process of stickers with a milder, calendering process. 【Background technique】 [0002] Traditional processing technology should be used in a process of casting, wood treatment, sheet press stickers, and finished production, equipment, equipment, equipment, etc. There are many types, the area is large, due to the cumbersome processing process, the length of processing cycle, the need to invest will increase accordingly, the cost is higher, but also more process, not only increase the waste of the processing process, the increase in the production of the product, the process The increasing factors of adverse influencing factors further lead to an increase in production costs. [Summary] [0003] It is an object of the present invention to overcome the defects of the existing pressurized stickers and long-term processing cycle, and provide an integrat...
