The invention provides a
coating device for
paper cup production, and belongs to the technical field of
paper cup processing, the
coating device comprises a transmission frame and a spraying frame, a
paperboard is arranged above the transmission frame, the transmission frame is connected with a lifting
assembly, the transmission frame is connected with a collecting box, the
coating device further comprises a trowelling
assembly, the trowelling
assembly is connected with a hot-
air blower, and the hot-
air blower is connected with the spraying frame. The trowelling assembly is used for uniformly scraping a coating on the surface of the
paperboard; the device has the beneficial effects that through the lifting assembly and a V-shaped scraper of the trowelling assembly, it can be guaranteed that the thickness of a coating is uniform, redundant paint can be guided to a collecting box and can be recycled after being treated, and the production cost is reduced; meanwhile, the
air heater synchronously blows out hot air after the coating is scraped, rapid curing of the coating is promoted, the product quality is improved, the
air heater can switch
airflow paths to automatically clean the scraping plate, residual coating is stripped through high-speed
airflow, it is avoided that subsequent use is affected by
drying and
caking, the manual cleaning cost is saved, and the long-term scraping precision is guaranteed.
