UV primer paint spraying line

Abstract

The invention discloses a UV primer paint spraying line. The UV primer paint spraying line comprises a paint spraying device, a paint mist separating device, a control cabinet, a conveyor belt I, a drying device and a conveyor belt II, wherein the paint mist separating device is arranged in the paint spraying device; the control cabinet is arranged at one side of the paint spraying device; the twoends of the paint spraying device are equipped with the conveyor belt I; the drying device is arranged at one side of the conveyor belt I; the conveyor belt II is arranged in the drying device; and the conveyor belt II extends to the two sides of the drying device. The UV primer paint spraying device is used for heating UV paint to reduce viscosity of the UV paint, and avoids generation of a phenomenon that UV paint blocks a spray head or sags on a workpiece; according to the width of the workpiece, a solenoid valve can control working quantity of spray guns during spraying, and reduces unnecessary waste of UV paint; UV paint gas spray gathered inside a box body is not in contact with the workpiece under action of a shutter and a negative-pressure device, so that the spraying effect is guaranteed; and UV paint in a pipeline flows back into a UV paint barrel while not used, so that smoothness in the pipeline is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of painting, in particular to a UV primer painting line. Background technique [0002] UV paint is currently the most widely used furniture paint. Its main features are: after strong ultraviolet light curing treatment, the color is stable, and it will last forever. It can effectively solve the problem of fading and color difference of the door panel. Orange peel is one of the more environmentally friendly and healthy paint door panels in the world. The hardness of the door panel is twice that of other paint door panels. It is resistant to scratches, acid and alkali, and is not easy to deform; [0003] Need to use UV primer spraying line when using UV paint to spray furniture, and existing UV primer spraying line has the following problems in use: 1) because UV paint is ultraviolet photocuring paint, does not pass through ultraviolet photocuring Always maintain a liquid state, it is easy to hang when sprayed...

Problems solved by technology

[0003] Need to use UV primer spraying line when using UV paint to spray furniture, and existing UV primer spraying line has the following problems in use: 1) because UV paint is ultraviolet photocuring paint, does not pass through ultraviolet photocuring Always maintain a liquid state, it is easy to hang when sprayed on the workpiece, and it is difficult to control the amount of diluent and curing agent added. If the concentration of UV paint is too high, it is easy to block the nozzle, resulting in the failure of spraying of UV paint, resulting in the failure of the painting line. Normal work; 2) When spraying UV paint on the workpiece, the workpiece is usually placed in a closed box. Since the UV paint mist will spread to every corner of the box during painting, the UV paint mist will form after gathering. After a certain volume, it will drip down, and it will affect the spraying effect after dripping on the workpiece. The width of the workpiece is different. Necessary waste; 3) Due to the different heights of the workpieces, the height of the spray gun of the existing UV primer spraying line cannot be adjusted, and the effect of spraying cannot be guaranteed, so secondary spraying is required, which reduces work efficiency; 4) UV paint passes through the pipeline The spray gun sprays the workpiece. After the spraying work is completed, there is still UV paint in the pipeline. If the UV paint in the pipeline does not flow for a long time, it will solidify in the pipeline and block the pipeline, causing the UV paint to fail to flow normally during the next spraying. Normal operation of the spraying device
