Description

Paint spraying and coloring equipment for transparent glass cup Technical Field The application relates to the technical field of paint spraying, in particular to paint spraying and coloring equipment for a transparent glass cup. Background Transparent glass products are widely applied to the fields of catering, gifts, home decoration and the like by virtue of clear and bright texture. However, the inherent transparency becomes a visual advantage and also causes problems of monotonous appearance and serious homogenization of the product. To increase the added value of the product, surface coloring and decorating of glass cups has become a common process. The glass cup is characterized in that the glass cup is provided with a glass body, a paint layer and a transparent texture, wherein the glass cup is provided with a transparent texture, a transparent texture and a rich light and shadow level, and the transparent texture is characterized in that the glass cup is provided with a transparent texture, a transparent texture and a rich light and shadow level, and the transparent texture is provided with a transparent texture. Although the inside paint spraying process has remarkable advantages, a series of serious technical challenges are still faced in actual industrial production, especially when high-efficiency and high-quality paint spraying is performed on the most common round-mouth cylindrical glass, and the following points are mainly shown: 1. The defect amplification effect and detection interference caused by the transparent material and the cylindrical structure are that the glass material has high light transmittance, the surface is an inert silica bond structure, and the cylindrical inner wall is a continuous arc-shaped curved surface. The characteristic causes any tiny defects generated in the paint spraying process, such as uneven paint film thickness, local missing spray, sagging or pinhole bubbles, to be extremely amplified under the transmission and refraction effects of the transparent medium, and can be clearly identified by naked eyes, thus leading to low product qualification rate. More particularly, the transparent glass surface reflects a fixed ambient light source (e.g., factory building lights, window lights) and forms a strong ambient light image at a specific angle. The reflected light spot can cover the real paint surface condition below the reflected light spot, so that part of defective products cannot be perceived in time at a fixed observation point. Operators manually find the non-reflection observation angle capable of avoiding the defects of reflection and clear observation, and the non-reflection observation angle is often spontaneously fixed at a certain station for a long time, so that the detection sites are limited, and the operators are exposed to harmful paint mist due to the fact that the operators are close to a paint spraying station for a long time, and the health risk is aggravated. If a conventional sealing scheme of adding a transparent observation window is adopted, double reflection superposition of the observation window glass and the cup glass can be caused, serious double images are generated, and visual judgment is further interfered. 2. In order to realize multi-angle detection, paint spraying equipment always needs to be kept in an open or semi-open layout, but the paint spraying equipment directly causes atomized paint particles (with the diameter of about 5-50 mu m) to be scattered to workshop environment in a large quantity. In the prior art, the effective attachment rate of the paint is usually only 30-40%, and the rest of the paint is a pollution source, so that equipment and sites are polluted, the cleaning cost is high, and the respiratory system health of operators is more endangered. The scattered paint also means serious waste of raw materials, and directly increases the production cost. 3. The serious effect of ambient moisture on the paint film quality is that in an incompletely closed environment, the plant humidity (especially above 60%) is difficult to control. Atomized paint is easy to mix with moisture in the air in the conveying process to form an oil-in-water structure, and meanwhile, the surface of the glass at low temperature can condense a invisible water film. The paint and the glass inert surface can be seriously hindered from being effectively adsorbed and combined, so that the paint film has the defects of blushing, foaming, shrinkage and the like, the adhesive force is greatly reduced, the paint film is easy to flake and fall off in the subsequent test, and the rejection rate can be increased by more than 30% in wet seasons. 4. The problem of uniformity control of paint spraying on the cylindrical inner wall is that when the cup opening is sprayed inwards, atomized paint naturally tends to be deposited on the cup bottom due to the influence of gravity, so that a paint film on the cylindrical inner wall of the cup body is thinne
