Description

Technical Field

[0001] The utility model relates to the technical field of coating spraying equipment, in particular to a spraying device for water-based coating construction. Background Art

[0002] After retrieval, the patent application No. 202121337533.0 discloses water-based coating equipment, including: a trolley, above which there are a motor and a paint bucket, and the paint bucket is connected with a spray head; a spraying device for evenly spraying water-based paint, which is connected with the trolley; a stirring device for stirring the paint during spraying, which is connected with the trolley.

[0003] During the use of the water-based coating equipment in this patent application, the stirring blade is driven to rotate horizontally relative to the paint bucket by using a motor, transmission parts and a rotating shaft, and at the same time, the toothed ring in the paint bucket drives the stirring blade to rotate longitudinally through a gear, improving the stirring effect of the paint in the paint bucket and preventing the paint from precipitating and stratifying. However, during such use, since both the toothed ring and the gear are located inside the paint bucket and are in direct contact with the paint, it is easy for the paint to adhere to the outer walls of the teeth of both the toothed ring and the gear to form blockages, making the stirring blade unable to rotate normally, affecting the stirring effect of the paint in the paint bucket by this equipment, and the toothed ring and the gear are also easily corroded due to long-term contact with the paint, reducing the service life of this equipment. There is room for improvement. For this reason, we propose a spraying device for water-based coating construction. Content of the Utility Model

[0019] 1. The spraying device for applying water-based coatings, by setting up a stirring mechanism and a flipping mechanism. During use, the driving motor is controlled to start. The output end of the driving motor drives the rotating shaft to rotate through a transmission component. The rotating shaft drives multiple stirring blades on the rotating cylinder to rotate horizontally to stir the coatings in the inner cavity of the coating barrel.

And the multiple passive steering gears are fixedly connected to the top wall surface of the inner cavity of the coating barrel through passive support rods to keep their positions unchanged. Thus, it forces the multiple active steering gears meshing with the multiple passive steering gears to drive the multiple stirring blades to rotate longitudinally through multiple stirring shafts to stir the coatings. The combination of these two stirring methods improves the stirring effect of the device on the coatings to prevent the coatings from precipitating and stratifying. The above operations are simple and practical, and the structure is reasonable and compact.
