Metal part protective layer multi-directional spraying mechanism

Abstract

The invention discloses a metal part protective layer multi-directional spraying mechanism. The metal part protective layer multi-directional spraying mechanism comprises a spraying chamber, a pump body, a protective liquid storage tank, a spraying mechanism and a conveyor belt. The conveyor belt is mounted on a rack and passes through the spraying chamber. A plurality of part positioning plates used for fixing metal parts are mounted on the conveyor belt. The part positioning plates independently rotate relative to the conveyor belt. The protective liquid storage tank is mounted on the top ofthe spraying chamber through a supporting frame. The bottom of the protective liquid storage tank is connected with a liquid delivery pipe. The pump body is mounted on the liquid delivery pipe. The liquid delivery pipe is connected with the spraying mechanism mounted in the spraying chamber and used for spraying protective liquid to the surfaces of the metal parts. The metal part protective layermulti-directional spraying mechanism has the beneficial effects that the spraying mechanism can spray the protective liquid to the metal parts efficiently and particularly conduct multi-angle protective liquid spraying on the surfaces of the metal parts through a vertical spray nozzle and circumferential spray nozzles and greatly improves the protective layer spraying effect through cooperation with rotating of the positioning plates; moreover, the excessive protective liquid can be effectively recycled, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a multi-directional spraying mechanism for a protective layer of a metal fitting. Background technique [0002] At present, in the production and manufacture of metal fittings, in order to prevent oxidation and corrosion of the metal surface, it is necessary to spray a protective layer on the surface of the fittings to isolate the surface of the metal fittings from the surrounding corrosive medium, thereby preventing corrosion. Spraying the protective layer is usually carried out in a spraying box, the metal fittings are placed on the shelf in the spraying box, and the protective liquid is evenly sprayed onto the surface of the metal fittings with a spray gun. In order to make the surface of the metal fittings evenly sprayed for better protection, it is necessary to continuously rotate the metal fittings so that each surface can be sprayed in place. In the prior art...

AI Technical Summary

Problems solved by technology

In order to make the surface of the metal fittings evenly sprayed for better protection, it is necessary to continuously rotate the metal fittings so that each surface can be sprayed in place. In the prior art, it is necessary to manually rotate the rack, which is inconvenient to use and low in production efficiency.

In addition, due to the generation of harmful gas and waste liquid during the spraying process, in the prior art, the waste gas is directly discharged into the external air, and the waste liquid is washed and mixed with water and discharged to the outside, which seriously affects the health of workers and easily leads to environmental pollution.
