Rotating piece of spraying device for metal

Abstract

The invention discloses a rotating piece of a spraying device for metal, and relates to the field of coating equipment. The rotating piece of the spraying device for the metal comprises a spraying device and a rotating device, wherein the spraying device comprises a spraying pipe, the rear end of the spraying pipe is connected with a spraying machine, and a spraying head is arranged at the front end of the spraying pipe; the rotating device comprises a baffle plate, a through hole is formed in the middle of the baffle plate, protective plate assemblies are symmetrically arranged on the left side of the front end surface of the baffle plate and the right side of the front end surface of the baffle plate, and the protective plate assemblies are parallel to each other; the spraying pipe penetrates through the through hole and is arranged between the protective plate assemblies; the protective plate assemblies comprise protective plates, horizontal sliding grooves are arranged on the innersurfaces of the protective plates in an up-down symmetry mode, and an arc-shaped sliding groove is connected between the front ends of the sliding grooves; and a fixing block is arranged on the spraying head, rotating shafts are symmetrically arranged at the two ends of the fixing block, a cylindrical gear is fixedly connected to the rotating shafts, the cylindrical gear is arranged in the horizontal sliding grooves, a transmission chain is arranged in the bottom of the horizontal sliding groove, and the transmission chain is connected with the cylindrical gear in a matched mode. According tothe rotating piece of the spraying device for the metal, spraying of a rectangular pipe from different angles by an operator can be realized by changing the spraying angles of the spraying head.

Description

technical field [0001] The invention relates to the field of painting equipment, in particular to a rotating part of a metal spraying device. Background technique [0002] The metal protection methods currently used can be roughly divided into three categories: one is anodic oxidation treatment, that is, an anodic oxidation film with a thickness of tens of microns is formed on the metal surface, but due to the large energy consumption of the anodic oxidation process and the contamination of the electrolyte solution Serious, difficult to handle, and its application is limited; the second type is chemical conversion coating, that is, soaking metal parts in a solution of a certain composition, and forming a layer of chemical conversion coating by chemical reaction at a certain temperature, which is now the most widely used It is the chemical oxidation of chromate, but chromate is a carcinogenic toxic substance. The World Environmental Protection Organization has proposed to res...

The World Environmental Protection Organization has proposed to restrict the use of chromate and other chromate-containing compounds; the third category is organic coatings, that is, on metal surfaces Apply an organic coating to improve the appearance and physicochemical properties of the metal

[0003] When people are spraying, they usually aim the nozzle at the position to be sprayed. When spraying rectangular tubes, they need to spray in all directions of the rectangular tubes. For different planes of the rectangular tubes, the operator needs to Standing at different positions of the rectangular tube, this spraying method is time-consuming and laborious
