A plastic spraying device

Abstract

The invention relates to a molding powder spraying device. The device comprises a heating chamber and a heating base; the middle of the heating chamber is provided with a molding powder inlet pipe, aspraying gun is fixedly connected with the upper portion of the heating chamber, a nozzle is rotatably connected with the spraying gun, holes are formed in the nozzle, a molding powder spraying pipe is arranged in the spraying gun, the molding powder spaying pipe is communicated with the molding powder inlet pipe, a first baffle plate is movably connected with the position where the molding powderspraying pipe and the molding powder inlet pipe are communicated, the end, away from the molding powder inlet pipe, of the molding powder spraying pipe is connected with the nozzle, a first sliding pipe is connected with the molding powder spraying pipe, a sliding block is connected in the first sliding pipe, and a pull rod is connected with the other end of the sliding block; a molding powder pipe is connected with the heating chamber, the end, away from the heating chamber, of the molding powder pipe is connected with a molding powder box, a plurality of transparent molding powder bottles are arranged in the molding powder box, first openings are formed in the upper portions of the molding powder bottles, a second sliding groove is formed in the upper portion of the molding powder box,a second opening is formed in the second sliding groove, and one end of the molding powder pipe is slidably connected in the second sliding groove. The problem of uneven spraying due to the fact thatmolding powder cannot be sprayed out timely is solved.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a plastic spraying device. Background technique [0002] Plastic spraying refers to a treatment process for industrial metal surfaces. Plastic powder is a powder coating, which is a new type of solvent-free 100% solid powder coating. There are two types of coatings: thermoplastic powder coatings and thermosetting powder coatings. Coatings are prepared by mixing special resins, pigments and fillers, curing agents and other additives in a certain proportion, and then through hot extrusion, crushing and sieving. They are stable in storage at room temperature. After electrostatic spraying or fluidized bed dipping, they are heated and baked to melt and solidify to form a flat and bright permanent coating film to achieve the purpose of decoration and anti-corrosion. [0003] Traditional plastic spraying equipment usually can only spray a single type of plastic powder, which has a sm...
