Description

Technical Field

[0001] The utility model relates to the technical field of parts spraying, in particular to a parts spraying device with a quick-install spray head. Background Art

[0002] In the processing and production of parts, it is often necessary to spray their exterior. By spraying a certain material, the parts can be protected from rust or decorated, and can also achieve the purpose of sound insulation, heat insulation, fire prevention, etc. Therefore, material spraying is an important part of parts processing;

[0003] The parts spraying device in the prior art needs to act on different types of workpieces, so it is necessary to switch between multiple nozzles. However, the existing device is usually only equipped with one nozzle. When replacing other types of nozzles, it needs to be disassembled and reinstalled. The whole process is time-consuming and labor-intensive, delaying production and processing. When switching back and forth between different types of nozzles, it brings about constant disassembly and assembly, and the workload is huge. In addition, since the nozzles of the existing devices are relatively fixed, it is impossible to effectively spray the grooves, grooves, gaps and other parts of complex parts. For this reason, we propose a parts spraying device with a quick-install nozzle. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a parts spraying device with a quick-install spray head. The device has a reliable spray head replacement unit. By clamping the three reversing rods with fingers and pulling them downward, the original spray head can be withdrawn from the sleeve pipe port, and the spray head to be used can be rotated to the lower side of the pressurized silo at the same time, so as to realize the quick installation of the spray head. The device also has a reliable parts spraying unit, which can clamp and fix the parts placed on the upper end of the movable platform, so as to facilitate the subsequent spraying process. The second motor can drive the movable platform and the parts placed on it to tilt left and right in a cycle, and cooperate with the front and back swing of the mounting rocker arm to make the grooves, crevices and other areas of the parts that are not easy to spray be effectively sprayed, which can effectively solve the problems in the background technology.
