Problems solved by technology

[0003] In order to protect the environment and avoid pollution, electrostatic spraying is usually carried out in the powder spraying room. The powder spraying room is generally equipped with an inlet and outlet and a hanging conveyor chain on the top of the powder spraying room. The workpiece is transported into the powder spraying room through the hanging conveyor chain. Inlet, and through the powder spraying pipes and spray heads fixed in the powder spraying room, the assembly line powder spraying operation is carried out until the workpiece is transported out of the material outlet. The excess powder on the surface is not conducive to the quality assurance of the workpiece; the powder room cannot maintain the

Example Embodiment

[0025] Example 1

[0026] Such as figure 1 , figure 2 As shown, this embodiment provides a powder spraying room for electrostatic spraying, including a first room structure 100 and a second room structure 200, the first room structure 100 and the second room structure 200 are two independent The two are connected to each other, but the channel diameter should be as small as possible, and only for the transportation and circulation of workpieces. The hanging conveyor chain in the prior art is set in the first house structure 100 and the second house structure 200 above the top, while the tops of the first housing structure 100 and the second housing structure 200 only have small openings for the hooks to be placed and transported. The hanging conveyor chain can also be fixed to the first housing structure 100 and the second housing structure. Below the top of the house structure 200, the hanging conveyor chain is located in the house to avoid opening small openings;

Example Embodiment

[0031] Example 2

[0032] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the spraying area 120 is provided with a powder spraying gun 121, which is used to drive the powder spraying gun 121 along the extension direction of the spraying area 120 (same as the workpiece transport direction ) A moving moving mechanism 122 and a lifting mechanism 123 for driving the powder spray gun 121 to rise and fall. The powder spray gun 121, the moving mechanism 122 and the lifting mechanism 123 are provided on both sides of the spray replenishing area 120, so as to perform respray operations on both sides of the workpiece at the same time. The powder spray gun 121 is connected with an air pump and a powder supply barrel through a powder pipeline, and the air pump is used to pump the powder in the powder supply barrel into the powder pipeline for the powder spray gun 121 to spray. The above design facilitates the positioning of the replenishing spray p...

Abstract

The invention relates to the technical field of powder spraying, and discloses a powder spraying room for electrostatic spraying. The powder spraying room comprises a first room body structure and a second room body structure; the first room body structure is internally divided into a spraying area and a spraying supplementing area; the second room body structure is close to and communicates withthe spraying supplementing area; a pulse recovery device is arranged outside the second room body structure, wherein an inlet of the pulse recovery device communicates with the second room body structure; the pulse recovery device comprises a fan, a pulse filter element, a pulse solenoid valve and a powder recovery barrel; the fan is located on the upper portion of the pulse recovery device; the pulse filter element and the pulse solenoid valve are located in the middle of the pulse recovery device; the pulse filter element communicates with the fan through the pulse solenoid valve; and the powder recovery barrel is located at the bottom of the pulse recovery device and detachably connected with the pulse recovery device, and idler wheels are arranged at the bottom of the powder recovery barrel. The powder spraying room can assist in checking and guaranteeing the workpiece powder spraying quality in real time.

Description

technical field [0001] The invention relates to the technical field of powder spraying, in particular to a powder spraying booth for electrostatic spraying. Background technique [0002] The surface of metal structural parts, cold-rolled steel sheets, galvanized steel sheets, and aluminum sheets will be sprayed with external powder in order to maintain a long-term aesthetic effect and service life, and the most popular one is electrostatic powder spraying. [0003] In order to protect the environment and avoid pollution, electrostatic spraying is usually carried out in the powder spraying room. The powder spraying room is generally equipped with an inlet and outlet and a hanging conveyor chain on the top of the powder spraying room. The workpiece is transported into the powder spraying room through the hanging conveyor chain. Inlet, and through the powder spraying pipes and spray heads fixed in the powder spraying room, the assembly line powder spraying operation is carried ...
