Operation method for quick magic powder replacing system

Abstract

The invention relates to the field of coating equipment, in particular to an operation method for a quick magic powder replacing system. The operation method can achieve self filtering on inferior powder and quick magic powder replacing of tail powder. The operation method comprises the steps of (1) early-stage preparation, (2) workpiece spraying, (3) primary recovering, (4) secondary recovering and the like. The operation method has the following beneficial effects that a thin filter screen can filter powder doped into the spraying powder and having the large grain size, the spraying homogeneity is improved, and the sprayed coating smoothness is improved; (2) a recovering bin can quickly and conveniently recover the tail powder, and waste caused by idle spraying and adverse effects on thework environment are avoided; and (3) a candle filter can automatically clean dust accumulated on a filter element of the filter, the filtering effect is greatly improved, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of coating equipment, in particular to an operation method of a system capable of self-filtering low-quality powders and tail powder quick magic powder replacement. Background technique [0002] A spray gun is a device that uses liquid or compressed air to release quickly as power. There are two types of spray guns: general pressure type and pressurized type. The spray gun also has a pressure spray gun, a card music spray gun, and an automatic recovery spray gun. The application of the spray gun in the industry can be directly loaded with paint, that is, a simple spray gun can be installed in automatic equipment, such as automatic glue spraying machine, automatic glue applicator, automatic paint spraying machine, coating machine and other spraying equipment. [0003] The nozzles used in the powder automatic spray guns in the prior art only have the function of simply spraying powder. In some powder coating equipment...

Problems solved by technology

[0008] In order to solve the problem that the nozzles used in the powder automatic spray guns in the prior art only have the function of simply spraying powder, in some powder spraying equipment that requires frequent powder change and fast powder change, the existing spray gun needs to be replaced when changing powder. Clean up the powder residue in the spray head. Cleaning is often carried out by empty spraying in the spray room or replacing the spray head. Cleaning up the residual powder by empty spraying not only wastes the powder, but also causes the powder to be sprayed out. Finally, if there is no spraying target, it is easy to fly in the spraying room, which will have a great adverse effect on the working environment. If the method of replacing the nozzle is adopted, the efficiency will be very low. Poor, manual cleaning is time-consuming and labor-intensive and easily reduces production efficiency. The first purpose of the present invention is to realize self-filtering of inferior powders and fast recovery of tailing powder; the second purpose of the present invention is to automatically clean and accumulate The dust on the filter element, the filtering effect is greatly improved, no manual operation is required, and a quick magic powder change system operation method that effectively improves production efficiency
