Description
Technical Field
The invention relates to a chain transmission workbench multi-spray-gun mini-character paint spraying machine and a working method thereof, belonging to the technical field of automatic paint spraying of advertisement mini-characters.
Background
With the rapid development of the industries such as manufacturing of advertisement three-dimensional characters, decoration and fitment, machining, sheet metal processing of various metal plates and the like, the requirements on the processing quality of the advertisement three-dimensional characters and the like are higher and higher. The three-dimensional characters of advertisement still adopt artifical spraying paint in a large number now, and the artifical uneven problem in surface that sprays paint exists because the people hand is sprayed paint and has been guaranteed that spray gun and work piece frame distance are the same forever, and mechanical spraying paint just can spout very evenly, because the distance between the spray gun of machinery and the work piece frame and the speed of spraying paint all can keep the same. However, the existing mechanical paint spraying only adopts simple transverse or longitudinal sweeping and spraying, which not only wastes a large amount of paint, but also can not reach the paint spraying quality. A novel luminous character called mini character appears in the advertisement identification industry at present, and the luminous character calling mini character is mainly applied to product propaganda of various shopping malls, hotels and the like. The mini characters are provided with LED light sources on the back, the surface of the mini characters emits bright light, but the side faces of the mini characters cannot emit light, and the mini characters are extremely strong in stereoscopic impression. Therefore, the side of the character is painted for three times, the first time is painted with the whitening paint, namely the paint has the performance of increasing the brightness, the surface brightness is increased after the LED luminous source on the back is lightened, the second time is the shading paint, the mini character is surface-luminous, and does not need side surface-luminous, so that the side surface needs to be covered with the special shading paint, and the third time is painted according to the color required by a client, so that the advertising three-dimensional character effect that the side surface does not emit light but the surface emits light is achieved. In the actual paint spraying process, because some characters are too small, the middle hole is not carved from top to bottom when being carved, and the shading paint is difficult to spray on the middle hole and cannot penetrate out brightness because of the rebound of air pressure when being manually sprayed. How to solve the problems of large paint spraying amount, high quality requirement, variable fonts, paint saving, environmental protection, high efficiency and great care in the industry.
