Abstract

The invention discloses a circulating backflow type paint spraying device for automobile part production, and belongs to the technical field of paint spraying. According to the scheme, a nozzle is blocked through a second electromagnetic valve, and then new paint washes a pipeline through a branch channel, so that old paint remaining in the pipeline is pushed into the bottom of a liquid storage cavity; the phenomenon that due to the fact that the viscosity of old paint is too high, a spray head is blocked is effectively avoided, a plurality of slow release holes are formed in a disc and matched with a magnetic block to attract a magnetic ring, the old paint can be slowly squeezed to the position above the disc to be mixed with new paint entering from the position above a liquid storage cavity, the viscosity of the old paint is effectively reduced, and the use efficiency of the paint is improved; and after the internal pressure of the liquid storage cavity reaches a threshold value, the one-way electromagnetic valve is opened, and the first electromagnetic valve is closed, so that the mixed paint is ejected out through the one-way pressure valve and the spray pipe, the mixing degree of new and old paint is effectively improved, and color difference is reduced.

Description

technical field

[0001] The invention relates to the technical field of paint spraying, and more particularly, to a circulating-return type paint spraying device used in the production of auto parts. Background technique

[0002] Spraying is a coating method that is dispersed into uniform and fine droplets by means of pressure or centrifugal force through a spray gun or disc atomizer, and is applied to the surface of the object to be coated. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivatives of the above-mentioned basic spraying forms, such as high-flow and low-pressure atomizing spraying, thermal spraying, automatic spraying, multi-group spraying, etc.

[0003] With the improvement of people's living standards, people's consumption of automobiles is also increasing, and the market for auto parts is becoming larger and larger. In the production process of auto parts, for the sake of beauty and anti-corrosion effect, the surfa...

Examples

Embodiment 1

[0043] see Figure 1-6 , a kind of paint spraying device used for the production of auto parts, including a spraying box 1, the spraying box 1 includes a spraying chamber 101 opened at its upper end and a collection cavity 102 opened at its lower end, and the inner side wall of the spraying chamber 101 is slidably connected with a sliding bracket 2. A spray gun body 3 is fixedly connected to the other end of the sliding bracket 2. The spray gun body 3 includes a rotating seat 31 that is fixedly connected to the sliding bracket 2. The lower end of the rotating seat 31 is provided with a spray gun column 32, and a liquid storage chamber 323 is opened inside the spray gun column 32. The upper end of the liquid storage chamber 323 is provided with a main channel 321 that communicates with the outside of the rotating seat 31. The upper end of the main channel 321 is connected to the external paint box through the main pipeline. The side wall of the sub-channel 322 is connected to the...
