Anti-diffusion aluminum coating spraying machine and spraying method thereof

Abstract

The invention discloses an anti-diffusion aluminum coating spraying machine and a spraying method thereof. The anti-diffusion aluminum coating spraying machine comprises a handheld barrel and a conveying pump, wherein a discharging opening is formed in the front side of a bottom plate of the handheld barrel, a square flat spraying box is vertically and fixedly connected to the lower side of the discharging opening, and a conveying hose is connected to the discharging end of the conveying pump; and a uniform discharging mechanism is arranged between a square flat spraying box and the handheld barrel. According to the anti-diffusion aluminum coating spraying machine, a pneumatic pump sprays strong-pressure airflow to the position under the pneumatic pump through a spraying pipe, and the airflow acts on outer strip-shaped pressing plates under the pneumatic pump, so that inner strip-shaped pressing plates move downwards to extrude aluminum coating in flat transition boxes, and the inner strip-shaped pressing plates and the cross section of an inner cavity of each flat transition box are identical in shape. The shape and the size of the inner cavity of each flat transition box are completely the same as those of the inner cavity of the square flat spraying box, so that the aluminum coating in the flat transition boxes is uniformly extruded and rushed into the square flat spraying box under stress, and is uniformly sprayed out from fine holes in a separation block.

Description

technical field [0001] The invention relates to the technical field of aluminum coating spraying devices, in particular to a diffusion-proof aluminum coating spraying machine and a spraying method thereof. Background technique [0002] Aluminum coatings refer to industrial coatings or paints containing aluminum metal pink materials, which can be used as protective coatings and can produce silver-gray decorative effects, etc., and aluminum coatings are generally sprayed on the surface end surface of related items by a sprayer. [0003] The traditional aluminum coating sprayer has the following shortcomings: [0004] When the general aluminum coating sprayer sprays related items, although the spray head of the existing equipment can limit the sprayed paint to a flat fluid, it will still spread the atomized paint body to the surrounding environment, pollute the surrounding environment, and generally spray The outgoing paint is directly transmitted and exported by the pressuriz...

Problems solved by technology

[0004] When the general aluminum coating spraying machine is spraying related items, although the spray head of the existing equipment can limit the sprayed paint into a flat fluid, it will still diffuse the atomized paint body to the surroundings, pollute the surrounding environment, and generally spray The sprayed paint is directly transported and exported by the pressurized pump body. It is easy to have a large impact force in the middle of the sprayed paint and a small impact force at the edge. This will easily lead to insufficient spraying effect. Affects paint transfer flow
