Spraying equipment for metal surface quick color changing

Abstract

The invention discloses spraying equipment for metal surface quick color changing. The spraying equipment comprises a working table, a spraying chamber, a hollow belt, an exhaust fan and a storing box, the spraying chamber is arranged above the working table, the inner wall of the spraying chamber is provided with symmetrical vertical sliding rails, the upper and lower sides of the vertical sliding rails are provided with symmetrical limiting blocks, a vertical movement rod is arranged between the two vertical sliding rails, and a hydraulic cylinder is arranged at the top of the vertical movement rod. The spraying equipment has the beneficial effects that the leakproofness of the spraying chamber is very high, the spraying chamber is communicated with the outside only through one overhauling door, coloring particulate matter can be effectively prevented from being scattered into outside air, and the coloring particulate matter can be sucked back through the exhaust fan even though small part of coloring particulate matter tries to be scattered out from a gap; and the exhaust fan can collect the coloring particulate matter sprayed to the periphery of a metal block into a storing groove, on one hand, environment pollution is prevented, on the other hand, resource recycling is achieved, and the spraying raw material cost is saved.

Description

technical field [0001] The invention belongs to the technical field of metal spraying, in particular to a spraying equipment for rapid color change on metal surfaces. Background technique [0002] The high-speed particle flow of molten metal is sprayed on the surface of the substrate to produce a coating material protection technology. The most widely used metal materials for spraying are zinc, aluminum and aluminum-zinc alloys, which are mainly used to protect large structural parts of steel. Electric arc spray guns are commonly used in the machinery industry, which are suitable for metal wire spraying. Flame spray guns are suitable for spraying metal wire as well as cermets and refractory oxides. Plasma arc spray guns and plasma spray welding are suitable for the spraying of various powders. Arc and flame spray guns are used for general anti-corrosion and repair, among them, for spraying zinc and aluminum, which can spray more than 200 kg per hour; Using high-energy pl...

AI Technical Summary

Problems solved by technology

[0003] The metal spraying of the prior art has the following problems: 1. During the spraying process of the metal spraying equipment, some colored particles may diffuse in the air, affecting the surrounding environmental quality and endangering people's health; 2. The coloring raw materials may not be all Spray on the surface of the metal block, some will be sprayed near the metal block, resulting in waste of resources
