Electrostatic powder vertical type spraying device

Abstract

The invention discloses an electrostatic powder vertical type spraying device. The electrostatic powder vertical type spraying device comprises a powder spraying house, a conveying device for conveying workpieces, a powder spraying device, a powder supplying device and a powder recycling device. The powder spraying house is provided with a workpiece input port and a workpiece output port both of which correspond to the conveying device. The electrostatic powder vertical type spraying device is characterized in that the powder recycling device comprises exhaust pipes arranged at the four corners of the powder spraying house respectively, and each exhaust pipe is provided with a gap for exhausting air from bottom to top, so that air flow in the powder spraying house is uniform and the negative pressure of air needing to be exhausted is reduced; the powder spraying device comprises electrostatic spray gun sets oppositely arranged on the two sides of the conveying device and a lifting device driving the electrostatic spray guns on the two sides to synchronously ascend and descend. The electrostatic powder vertical type spraying device is simple in structure and convenient to use and install; in the powder spraying production process, powder consumption is low, the one-time powder coating rate is high, the time taken to clean the powder house and the time taken to change powder are shortened, electric energy is saved, fewer operating workers are needed, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of aluminum profile surface treatment equipment, in particular to an electrostatic powder vertical spraying equipment. Background technique [0002] In the field of aluminum profile surface treatment, electrostatic powder spraying has become the most important treatment method in the industry, and vertical powder spraying is widely used by aluminum material factories because of its high efficiency and large production capacity. Powder coating uses the principle of electrostatic spraying to absorb the dry powder on the metal aluminum profile. After baking at a high temperature above 200 ℃, the powder solidifies into a solid and bright coating about 60 microns thick. A set of electrostatic powder spraying system is mainly composed of a set of powder supply device, one or several sets of electrostatic spray gun and control device, static electricity generating device (usually configured inside the electrostatic...

Problems solved by technology

The traditional vertical spraying production line needs two powder spraying booths to complete the two-sided spraying of the workpiece. When a vertical powder spraying booth completes the two-sided spraying, the workpiece needs to be rotated 180 degrees in the middle of the powder spraying room, and the production efficiency is low; and the traditional powder spraying The opening size of the conveying channel in the room is relatively large. This structure causes excessive negative pressure at the workpiece where the powder is sprayed. It is Necessary to Improve the Vertical Powder Spraying Booth
