Production technology and production equipment for wooden door with smooth paint surface

Abstract

The invention discloses a production technology and production equipment for a wooden door with a smooth paint surface. The production technology comprises the steps of plate drying, plate pressing, cutting, sanding, framing, wood wool removing, paint spraying, drying and packaging forming. Lignin fibers can be dissolved by using fiber digestion enzyme, wood wool is removed, after the wood wool is dissolved and removed by using the fiber digestion enzyme, on the basis of the characteristics of the fiber digestion enzyme, wood wool dissolving impurities on the upper surface of a wooden door protection layer can be directly cleaned away with clean water, and cleaning is thorough, convenient and simple; the protective layer is coated on the surface of the wooden door, so that the moisture content of the wooden door is guaranteed, moisture loss of the wooden door is prevented, erosion of outside harmful substances to the surface of the wooden door is better prevented, and the corrosion resistance is good; and due to the fact that the fiber digestion enzyme is used for removing the wood wool, the surface of the wooden door can be smooth, and painting is easier.

Description

technical field [0001] The invention relates to a production process and production equipment for a lacquered smooth wooden door. Background technique [0002] In wood cutting processing, it is easy to produce many soft and fine lignin fibers (wood wool) that have been cut but not completely separated from the wood surface. Although the wood surface has been finely planed, sanded, especially mechanically polished, the finish can be It meets certain requirements, but if you observe carefully, there are still some wood hairs left on the surface of the wood. The formation of wood wool is closely related to the fiber structure and processing conditions of wood. Most woods will produce wood hair, especially elm. Under the action of grinding pressure, these wood hairs often curl up and hide. Once the finishing dye solution, shellac varnish, etc. absorb water or other solvents, they will swell violently and stand upright, resulting in uneven and rough wood surfaces and affecting t...

AI Technical Summary

Problems solved by technology

[0004] 1. The seal between the baffle and the feed inlet is not tight, and the hot air in the box is easy to diverge to the outside of the box through the gap between the baffle and the feed inlet, resulting in heat loss;

[0005] 2. Although the structure is simple and the drying is uniform, a large amount of heat will be dissipated directly into the atmosphere through the box, resulting in a large power loss when the temperature in the box needs to be maintained.
