Powder spraying equipment for processing enamel workpieces and using method thereof

Abstract

The invention relates to the field of enamel production equipment, in particular to a powder spraying equipment for processing enamel workpieces and a method for using the powder spraying equipment, including a powder spraying room, a conveying chain and a fluidized bed, and a hanging rod for hanging metal workpieces is fixed on the conveying chain. Two limit platforms are fixed on both sides of the powder spraying room, and an anti-shake mechanism is fixed on the limit platform. A supporting platform is also fixed on the side wall of the powder spraying room, and an elastic powder mechanism is fixed on the support platform. The powder spraying room The organic casing is fixed at the bottom of the casing, and a cross-flow fan is arranged inside the casing. The outlet end of the casing is fixedly connected to the guide frame, and the lower guide port of the flow guide frame is connected to the dispersing mechanism through a Venturi tube. The powder spraying equipment for processing enamel workpieces and its use method maintain the stability of the metal workpiece through the anti-shake mechanism, improve the enamelling quality of the metal workpiece, and use the powder spring mechanism to shake off the powder that is not firmly bonded to the metal workpiece. Avoid falling on the outside of the powder spraying room, use the characteristics of the cross-flow fan to recover the powder, and avoid the blockage of the recovery channel.

[0002] Enamel is an inorganic glass enamel coated and fired on the surface of a metal base. Its manufacturing process includes glaze preparation, enamelling, drying, firing, and some need color decoration processing. Finally, product quality inspection and packaging are carried out. Among them, enameling is Coating enamel on the surface of the pretreated metal body can be divided into two types: wet enamel and dry enamel. Dry enamel is a coating method that uses enamel dry powder to coat the body, including the following three methods , dipping method, spray enamel method and spray enamel method, wherein the spray enamel method is a method of glazing by spraying glaze powder on the body, so that the enamel powder is directly sprayed on the metal body through a powder spray gun to form a uniform coating , the control, operation and recovery of this enamel powder can be fully automated, such as: Application No.: 201710124815.4 discloses a spray booth enamel production line, which uses a hanging conveyor to send metal workpieces into the powder spray booth, and uses The spray gun device sprays powder on the metal workpiece, and then uses the triangular plate powder suction channel, recovery filter blowback device, etc. to recycle the dropped powder to improve the powder utilization efficiency, but the metal workpiece is prone to shaking during the transportation process, resulting in powder spraying In addition, part of the powder sprayed on the surface of the metal workpiece is not firmly bonded, and it is easy to fall off the outside of the powder spraying room, which is difficult to recycle, affects the environment, and is not easy to clean; the powder that is not adhered to the metal workpiece in the powder spraying room Powder is easy to combine with water vapor and condense in the powder spraying room, so it is easy to cause blockage of the recovery port during recycling, which not only affects the recovery efficiency, but also is very troublesome. In view of this, we propose a powder spraying equipment for processing enamel workpieces and its use method
