Dewatering, drying and coating equipment for microwave waterborne wood paint furniture, and coating method

Abstract

The invention provides dewatering, drying and coating equipment for microwave waterborne wood paint furniture. The dewatering drying and coating equipment is characterized by comprising a box body, wherein a conveyer belt for conveying the furniture is arranged in the box body; a metal conveyer belt supporting plate is arranged below the conveyor belt; at least one group of side microwave generator units and at least one side three-edged microwave reflecting plate are respectively arranged at the left side and the right side of the box body; and at least one group of top microwave generator units and at least one top three-edged microwave reflecting plate are arranged at the top of the box body. The invention also provides a dewatering drying and coating method for microwave waterborne wood paint furniture by adopting the dewatering, drying and coating equipment for microwave waterborne wood paint furniture. Furniture subjected to the microwave treatment have relatively uniform heating temperature and water content in spite of the volume, the unique and complex shape, the non-uniform thickness of graving plate and the multi-layer baffles on the external surface layer and the internal layer on the back; and the furniture has no cracking, warping and deforming, thereby thoroughly solving the problem that the waterborne wood paint of furniture is hard to dry and dewater.

Description

technical field [0001] The invention relates to a device for coating water-based wood varnish on furniture and a coating method using the device. Background technique [0002] The biggest advantage of water-based paint with water as the medium is that it does not burn, has no danger of explosion, is non-toxic or low-toxic, and its organic volatile VOC content is low or even zero VOC, so it will not cause harm to humans and the ecological environment. . The use of water-based paint is especially important for the improvement of the home environment. It has immeasurable benefits for the living and healthy environment of human beings. It is an environmentally friendly paint and the mainstream of future paint development. [0003] Although water-based wood paint has been commercialized in the world for 40 years, due to the characteristics and characteristics of water-based paint, it is still a difficulty in large-scale continuous assembly line production. When the furniture is...

AI Technical Summary

Problems solved by technology

The traditional heating and drying is infiltrated from the outside to the inside. To dry all the water absorbed by the wood, a lot of heat is needed. The heating temperature of the layers and interlayers is more uneven, resulting in a multi-layer temperature gradient, and the moisture content of the wood also causes a multi-layer gradient, resulting in multi-layer stress, causing cracking, warping, deformation, etc. of the furniture, resulting in water-based wood paint. It is difficult to promote the furniture manufacturing industry
