Description

Production process and production equipment for smooth wooden door with painted surface

Technical Field

The invention relates to a production process and production equipment for a smooth wooden door with a painted surface.

Background

In wood cutting processes, a number of soft, fine lignin fibers (wood wool) are easily produced which have been cut but do not completely detach from the wood surface, and although the finish of the wood surface can be achieved by fine planing, sanding, and especially mechanical polishing, it is observed that there is still some wood wool remaining on the wood surface. The formation of wood wool is closely related to the fibrous structure of wood, processing conditions, etc., and most wood materials produce wood wool, especially elm. The wood wool is often curled, laid down and hidden under the action of grinding pressure, and is severely wetted and expanded once coated with water absorption components such as dye solution, shellac varnish and the like or other solvents and erected, so that the surface of the wood is uneven and rough, and the smoothness of a paint film is influenced;

in addition, in the production process of the prior wooden door, a drying box is required to be used for drying the wooden door, the drying box is used for the process equipment of drying, resin curing, pharmacy, baking varnish, electron, electroplating, pharmacy, printing baking, motor drying, transformer drying, industrial heat treatment, disinfection, heating, heat preservation and the like of polymer materials in factories and scientific research units, application number CN200920299385.0 discloses a drying box which comprises a box body, wherein a feed inlet is arranged on the box body, a baffle is hinged on the box body at the feed inlet, a corresponding baffle layer is arranged on the inner wall of the box body, a plurality of electric heating tubes which are arranged in parallel are arranged between the baffle and the inner wall of the box body, and the electric heating tubes are connected to a circuit control device through a circuit. The production benefit is improved, but the drying box still has the following defects:

1. the baffle plate and the feeding hole are not tightly sealed, and hot air in the box body is easily diffused to the outside of the box body through a gap between the baffle plate and the feeding hole, so that heat loss is caused;

2. although simple structure dries evenly, but a large amount of heats can directly be dispersed to the atmosphere through the box in, and the electric quantity that the loss is big when leading to need to keep the interior temperature of box.
