Description

Technical Field

[0001] The utility model relates to the technical field of coating spraying, in particular to an aluminum plate powder coating particle spraying device. Background Art

[0002] Powder coating is a new type of solvent-free solid powder coating. It has the characteristics of being solvent-free, pollution-free, recyclable, environmentally friendly, saving energy and resources, reducing labor intensity and having high mechanical strength of the coating film. Powder coating spraying device is a device that applies powder coating to different types of surfaces. This device usually consists of a spray gun, a conveying system, etc. It uses electrostatic attraction to attach the powder coating to the surface of the coated object, and solidifies after drying to form a strong and durable coating.

[0003] Powder spraying equipment is generally fixed with a steel wire, and then the aluminum plate is hung on the steel wire through a hook formed by bending the metal wire, and then a spray gun can be used for spraying. However, during use, the metal plate is manually hung on the steel wire and then sprayed directly. The existing powder spraying device is prone to generate a large amount of powder coating dust, and cannot prevent powder from escaping. It is easy to pollute the air near the equipment and is difficult to clean. At the same time, it is difficult to quickly and effectively recycle the spilled and residual powder coating, which will cause waste and affect the working environment, thereby causing unnecessary economic losses.

[0009] Preferably, the auxiliary mechanism includes a fixing rod fixed to the bottom of the inner wall of the bottom shell and an annular groove provided for the bottom of the disc.

[0010] Preferably, the reflux mechanism includes a feeder installed on one side of the bottom shell and a delivery pipe connected to the delivery port thereof, and also includes a storage box connected to the delivery pipe delivery port.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model fixes the aluminum plate through a clamping mechanism and performs spraying through a spraying mechanism. During the spraying process, a protective door is used to protect against scattering of powder coating particles. The protective door cooperates with the barrier mechanism and the state of the barrier mechanism components is changed while the protective door is pulled, so that powder coating particles are collected conveniently and dust coating is prevented from flying.

[0029] Working principle: First, open the protective door 4, and drive the rack plate 81 to move through the hinged rod 85. When the rack plate 81 moves, it meshes with the gear 82 to drive the baffle 84 to flip and close, and block the bottom of the spray shell 3. Then the staff can place the aluminum plate on the top of the baffle 84 for easy clamping, and then clamp and fix it through the clamping mechanism 5. Then the staff closes the protective door 4, and pushes the rack plate 81 through the hinged rod 85 to mesh with the gear 82, driving the baffle 84 to flip and open again, exposing the collection shell 11 below, which is convenient for collecting during the spraying process. The scattered powder coating particles cooperate with the protective door 4 to prevent the powder coating particles from floating in the air. While collecting the powder coating particles, the rotating motor 91 controls the rotation of the disc 92 and the wedge block 93 cooperates with the moving rod 94 to drive the collection shell 11 to move up and down to form a belt vibration, so that the powder coating particles on the top of the filter screen 12 are sieved to the inside of the collection shell 11, and then the sieved powder coating particles are pumped into the storage box 143 through the feeder 141, and then sprayed through the spraying mechanism 6 for secondary use. After the spraying is completed, the protective door 4 can be opened to take out the aluminum plate.
