Description

TECHNICAL FIELD

[0001] The utility model belongs to furniture manufacturing technical field relates to a continuous through formula spray dries integrated equipment. BACKGROUND

[0002] In the furniture manufacturing industry, paint spraying and paint baking constitute two key steps in the production process. Under normal circumstances, the cut plate first needs to be manually carried by workers to the paint spraying area and fixed there. Then, the plate to be painted surface is sprayed by an automatic nozzle. After the paint spraying process is completed, the plate needs to be carried again by workers to the paint baking area to complete the drying process.

[0003] At present, paint spraying and paint baking are operated as two independent processes, relying too much on manpower for transportation and adjustment. For example, in the plate feeding link, a number of workers need to carry the plate and adjust its position in the paint spraying equipment in turns. After the paint spraying is completed, a second carrying and position adjustment is needed so that the plate can enter the paint baking chamber. This operation mode limits the efficiency of the entire production process to the operation speed of the workers, and exposes the operators to the paint spraying and paint baking environment for a long time, inhaling a large amount of paint mist, which poses a threat to their health.

[0004] In addition, the paint layer drying process of the plate usually adopts hot air or infrared drying method, that is, the paint layer directly absorbs heat for drying. In this direct drying process, the surface of the paint layer dries first, while the inner layer still contains a high moisture content, resulting in layer-by-layer drying of the paint layer from the outside to the inside. This uneven drying method may cause the internal moisture to be unable to effectively discharge after the outside is dried, thereby forming bubbles in the paint layer, affecting the overall mechanical properties. When impacted, the paint layer is prone to layered cracking. At the same time, the water vapor in the paint layer evaporates violently in the direct drying process, causing internal defects in the paint layer and the surface to bulge, reducing the yield of the product. SUMMARY

[0005] The purpose of the utility model is to provide a continuous through formula spray dries integrated equipment for avoiding the paint layer bubbling problem caused by "the surface layer of the paint layer dries first, but the inner layer still maintains a high moisture content".

[0025] 1) The utility model realizes full automation of paint spraying and paint baking process, so that the whole processing flow does not need manual participation, thereby greatly reducing the health risk of workers in the paint spraying and paint baking links. Meanwhile, the cabinet board heating seat is used as the cabinet board placing seat to heat the cabinet board after paint spraying from the bottom, thereby effectively avoiding the paint layer blistering problem caused by "the surface layer of the paint layer dries first, but the inner layer still maintains a high moisture content". Meanwhile, since the heating plate directly contacts the cabinet board, the heat transfer efficiency is higher than the heating efficiency of the ambient temperature on the cabinet paint surface, thereby the length of the paint baking cavity can be significantly shortened, and the energy cost of heating and maintaining the preheating cavity and paint baking cavity temperature can be reduced.

[0026] 2) The utility model detects the environmental temperature change through the temperature sensor, so that when the cabinet board heating seat carries the cabinet board into the preheating cavity, the temperature sensor detects the environmental temperature rise, starts the heating plate to heat, so that the heating rate of the heating plate and the heating rate of the cabinet board gradually passing through the preheating cavity and the paint baking cavity are matched, so that the inside and outside of the paint layer are synchronously heated.
