Embodiment 1

[0027] A processing technique for integral molding of laminated veneer by laminating and calendering techniques, comprising the following steps:

[0028] a. Skinning: first use highly transparent polyurethane elastic UV resin to fill the veneer blank and dry it with a UV light source. The thickness of the veneer blank is 0.05mm, the wavelength of the UV light source is 480nm, and the drying time is 30min. Then the veneer is mirror-polished, and the veneer thickness error Controlled at 0.01-0.05mm, use a fully automatic seamless splicing machine to seamlessly splice multiple pieces of veneer, seamlessly splice the veneer along the longitudinal direction into a coil, 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 The overall appearance of the thin veneer is uniform and solid, and there is no abnormal transparent bottom;

[0029] b. Extrusion casting: put in plastic materials that can bond wel...

Embodiment 3

[0039] A processing technique for integral molding of laminated veneer by laminating and calendering techniques, comprising the following steps:

[0040] a. Skinning: First, use highly transparent polyurethane elastic UV resin to fill the veneer blank and dry it with a UV light source. The thickness of the veneer blank is 0.3mm, the wavelength of the UV light source is 600nm, and the drying time is 60min. Then, the veneer is mirror polished, and the veneer thickness error Controlled at 0.01-0.05mm, use a fully automatic seamless splicing machine to seamlessly splice multiple pieces of veneer, seamlessly splice the veneer along the horizontal direction to form a coil, and at the same time modify the bottom texture on the surface of the veneer, and fill it with the same wood grain color to ensure The overall appearance of the thin veneer is uniform and solid, and there is no abnormal transparent bottom;

Abstract

The invention discloses an integral forming processing technology for pressing and laminating veneers through a film spraying and calendering process. According to the technical scheme, the technologyis characterized by including the following steps of a, splicing skin, wherein the veneers are longitudinally or transversely seamlessly spliced into a sheet, the maximum width of the veneers is ensured, the surfaces of the veneers are decorated with transparent patterns, filling is conducted through the color the same as that of the wood patterns, and it is ensured that the thin veneers are unified in overall appearance, free of solid color abnormity, transparent and the like; b, conducting extruding and curtain coating, wherein one or more of plastic raw materials with different performanceare mixed and put into a material hopper of an extruder, extruding and curtain coating are conducted on a film spraying machine through heating, mixing, plasticizing and extruding to form a film, andthe thin film is adjusted to have the required thickness and bias; c, conducting film spraying and laminating, the spliced veneers and the high-temperature-resistant base film are introduced into a laminating roller group on the adjusted curtain coating film for multi-roller-group pressing; d, conducting cooling forming, wherein the laminated veneers are cooled, trimmed and then wound into a coiled material through a winding machine.

Description

【Technical field】 [0001] The invention belongs to the technical field of wood processing, and in particular relates to an integral molding processing technology for pressing and pasting veneer by using film coating and calendering technology. 【Background technique】 [0002] The traditional processing technology needs to use casting or blown film equipment, veneer processing equipment, sheet pressing equipment and cutting equipment, etc. After multiple processes such as film making, veneer treatment, sheet pressing, and finished product cutting, the equipment investment There are many types and a large area. Due to the cumbersome processing procedures and long processing cycle, the resources to be invested will increase accordingly, the cost is high, and there are many processes, which not only increases the waste of the processing process, but also increases the risk of defective products in the process. The unfavorable factors in the process increase, which further leads to...
