Anti-blocking adjustable thermosetting powder coating spraying device

Abstract

The invention belongs to the technical field of spraying devices, and particularly relates to an anti-blocking adjustable thermosetting powder coating spraying device which comprises a spraying box, gas conveying metal pipes are symmetrically arranged on the lower surface of the spraying box, the bottom ends of the gas conveying metal pipes are fixedly connected with a gas conveying machine, and the spraying box comprises an outer box shell. Refitted spraying pipes are evenly arranged on the upper portion of the inner wall of the outer box shell, a recycling device is arranged in the middle of the inner wall of the outer box shell, inner sliding boxes are symmetrically arranged on the left side and the right side of the recycling device, and spraying devices are arranged on the inner walls of the inner sliding boxes. After the modified spray pipe is filled with the device, the spray material in the modified spray pipe is pressurized and sprayed through the gas transmission machine, and the spray material amount filled in the modified spray pipe every time is fixed, so that the problem that the modified spray pipe is blocked by excessive spray material is avoided; therefore, the problem that the spraying function is affected due to the fact that the pipe body is blocked or residues exist in the pipe body when the device is in a long-time continuous working state is solved.

Description

technical field [0001] The invention belongs to the technical field of spraying devices, in particular to an anti-clogging adjustable thermosetting powder coating spraying device. Background technique [0002] Thermosetting powder coating refers to the use of thermosetting resin as a film-forming substance, and the addition of a curing agent for cross-linking reaction can form an insoluble and infusible hard coating after heating. At higher temperatures, the coating will not soften like a thermoplastic coating, but will only decompose. Since the resin used in the thermosetting powder coating is a prepolymer with a lower degree of polymerization and a lower molecular weight, the coating has better leveling and better decoration, and the low molecular weight prepolymer is cured. It can form network-like cross-linked macromolecules, so the coating has better corrosion resistance and mechanical properties. Therefore, the development of thermosetting powder coatings is particul...
