Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of painting powder rooms, in particular to a powder cleaning device for a guardrail painting powder room. Background Technique

[0002] The basic principle of a painting powder room is that a powder spraying device forms a high-voltage corona discharge field between the spray gun and the workpiece. When the powder particles are ejected from the nozzle and pass through the discharge area, they collect a large number of electrons, forming negatively charged particles, which are adsorbed onto the positively charged workpiece under the action of electrostatic attraction. At a certain thickness, the powder will have a repulsive effect with the particles and can no longer be adsorbed by the powder. After high-temperature baking and curing, the powder layer is leveled into a uniform thin film;

[0003] In the prior art for the powder cleaning operation of a painting powder room, usually after a guardrail is sprayed once in the painting powder room, the staff manually cleans the inside of the painting powder room. The operation is rather troublesome, and it is not conducive to the continuous spraying operation of the guardrail, affecting the spraying efficiency of the guardrail;

[0028] Refer to Figure 1 and Figure 4 Below the filter screen 8, a vibration mechanism for preventing powder coating from adhering to the filter screen 8 is provided. The vibration mechanism includes a driving motor 14, a connecting shaft 15, and a plurality of cams 16. The driving motor 14 is fixedly installed on the side wall of the machine body 1.
