Abstract

The invention discloses a PLC based spray gun automatic controller. The PLC based spray gun automatic controller comprises a PLC control cabinet, a lifter and an electrostatic generator, wherein the control signal output end of the PLC control cabinet is connected with the control signal input end of the electrostatic generator, the control signal input end of the lifter and the control signal input end of a spray gun respectively. The PLC based spray gun automatic controller conducts reasonable control on the electrostatic generator, the lifter and the spray gun respectively through a PLC, so that the empty spraying problem of the spray gun in an automatic spraying production line is decreased, spraying materials are saved, and spraying operation is accurate.

Description

Technical field [0001] The invention relates to a spray gun controller, in particular to a PLC-based automatic spray gun controller. Background technique [0002] In the industrial production of food packaging, spraying can beautify the appearance and anti-corrosion functions. Electrostatic spraying is based on the phenomenon of electrophoresis, using the painted workpiece and the paint as the anode and the cathode, and at the same time, under the action of the two-pole electric field, the use of "opposite attraction The principle of "adsorbs the paint on the surface of the painted workpiece. In the actual production, the control of the spray gun directly affects the thickness and uniformity of the coating. In the automatic spraying production line control, if the action of the spray gun is not properly controlled, it will cause a certain degree of air spraying of the spray gun, which not only increases the spraying cost, but also increases the load of the paint net collection d...
