Paint spraying equipment capable of realizing switching between high-pressure spraying and low-pressure spraying quickly

Abstract

The invention relates to paint spraying equipment capable of realizing switching between high-pressure spraying and low-pressure spraying quickly. A product placing and collecting device, a first station unit, a first spraying device, a second spraying device and a second station unit are arranged on an annular flow transmission line in sequence; the structures of the first spraying device and thesecond spraying device are the same; each of the first spraying device and the second spraying device comprises a box body and a spraying mechanism; a channel for the annular flow transmission line to cross and run is formed in each box body; a worktable is arranged along one side of each channel; a plurality of spraying mechanisms are arranged on each worktable in parallel; each spraying mechanism comprises a placement rod, a high-pressure spraying gun and a low-pressure spraying gun; each high-pressure spraying gun and the corresponding low-pressure spraying gun are plugged on the corresponding placement rod in a height adjustable manner; and each high-pressure spraying gun is positioned above the corresponding low-pressure spraying gum. A two-step coating product can be sprayed simultaneously in two spraying rooms (spraying devices) at one time; when the high-pressure spraying guns are specifically required to be used for spraying paint, the high-pressure spraying guns can be switched quickly; atomizing and injecting integrated spraying nozzles control the size of paint mist sprayed by the spraying guns; and fan-shaped controllers control the fan shapes of the paint sprayed bythe spraying guns.

Description

technical field [0001] The invention relates to a paint spraying device capable of quickly realizing high and low pressure spraying switching. Background technique [0002] At present, the spraying diameter of the high-pressure gun is generally greater than 1mm, the wind pressure is generally greater than 0.25MP, and the products sprayed by the high-pressure gun are rough and dry. [0003] The spraying diameter of the low-pressure gun is generally less than 1mm, the wind pressure is generally less than 0.25MP, and the products sprayed by the low-pressure gun are darker and brighter. [0004] For some products that require secondary coating, the primer is not silver powder coating, so it needs to be sprayed twice, and the product needs to be rotated 2 times on the painting line, which has a long production cycle and wastes costs; due to the large diameter of the high-pressure gun, the waste of paint Very high, some products that can be sprayed by high and low pressure guns c...

Problems solved by technology

[0004] For some products that require secondary coating, the primer is not silver powder coating, so it needs to be sprayed twice, and the product needs to be rotated 2 times on the painting line, which has a long production cycle and wastes costs; due to the large diameter of the high-pressure gun, the waste of paint Very high, some products that can be sprayed by high and low pressure guns consume 1 / 3 more paint than low pressure guns
