Full-automatic bend powder spraying device

Abstract

The invention relates to a full-automatic bend powder spraying device. A workbench, a powder spraying unit and a powder recycling unit are included. The workbench is used for containing a heated to-be-sprayed bend. The powder spraying unit comprises a walking assembly and further comprises a powder supply assembly and a high-temperature-resisting hose powder spraying gun which are arranged on thewalking assembly. The high-temperature-resisting hose powder spraying gun comprises a high-temperature-resisting hose, a powder sprayer arranged at the tail end of the high-temperature-resisting hoseand provided with a plurality of nozzles, a plurality of sets of centering guiding wheels wrapping the outer portion of the high-temperature-resisting hose and a plurality of powder supply pipes arranged in the high-temperature-resisting hose. One ends of the multiple powder supply pipes are in one-to-one corresponding connection with the nozzles, and the other ends of the multiple powder supply pipes are connected with the powder supply assembly. The powder recycling unit and the powder spraying unit are arranged on the two sides of the workbench correspondingly and used for collecting surplus powder in the powder spraying process. Compared with the prior art, the spraying process is finished in a full-automation manner, the surface spraying structure thickness is uniform, work environment pollution through dust can be avoided, and the full-automatic bend powder spraying device is suitable for bend interior powder spraying.

Description

technical field [0001] The invention relates to the field of powder coating, in particular to a fully automatic elbow powder coating device. Background technique [0002] In the current ground pipelines, urban construction and other industries, the use of various pipeline construction is very huge, and the use environment of various pipelines is very harsh, so it is very necessary to do a good job of coating with reliable quality. The coating technology for straight pipelines is relatively mature, but the coating technology for bent pipes is still relatively lacking. , poor coating quality and other factors, the elbow is the weak link of the pipeline, the frequent link of corrosion, perforation, leakage and other accidents, so it is very necessary to do a good job of the inner coating of the elbow, and the current market is due to the Due to the lack of spraying technology, few manufacturers have the ability to do a good job of the inner coating of the elbow. Most of them ...

Most of them use manual electrostatic powder spraying devices. During the spraying process, these devices will produce a large amount of unadsorbed powder, which will cause serious pollution to the air and directly affect the health of the operator and the surrounding environment; moreover, dust Entering is charged with the same charge as the paint particles, and adsorbed on the surface of the workpiece, which will easily cause poor film quality, waste raw powder, and cannot guarantee the quality of spraying
