Description

Glass production coating film solidification equipment Technical Field The utility model belongs to the technical field of glass processing and surface treatment, and particularly relates to a coating solidifying device for glass production. Background In the glass coating production process, the performance of the coating curing device directly influences the quality and the production efficiency of the coating. At present, various coating curing technologies based on high-temperature furnace heating or hot air circulation appear on the market, but the technologies still have a plurality of defects in practical application, and the uniformity and stability of the coating are affected. For example, chinese patent (publication No. CN104676458B, publication No. 2016, 11, 23) discloses an LED anti-reflection and anti-dazzle glass lampshade and a production method thereof. The technology heats the whole coated glass lampshade through a high-temperature furnace so as to realize stable solidification of the film layer. However, the mode of heating the film by the integral high-temperature furnace has higher energy consumption, and the temperature distribution is not uniform enough, so that the local thermal stress of the film is uneven, and the cracking or falling problem can be caused. In addition, the solution does not relate to effective control of solvent volatilization in the film coating process, which may lead to reduced uniformity of the film layer and influence the optical performance. For another example, chinese patent (publication No. CN111410434B, publication No. 2023, month 2 and 28) discloses a preheating method and equipment for producing coated glass. The technology adopts hot air to preheat the glass substrate and the coating liquid respectively, and uses the hot air to perform post-heating treatment again after coating so as to improve the adhesive force and the light transmittance of the film. Although the bonding force between the film layer and the base material is improved, the heat utilization rate of the heating mode of the open type hot air circulation is low, and the stability of the curing process can be disturbed by the change of the ambient temperature and humidity. Meanwhile, the technology lacks an effective adjusting means for internal stress of the film layer in the curing process, which may lead to increased brittleness and insufficient weather resistance of the film layer. The problems show that the existing coating curing device has certain limitations in the aspects of energy consumption, temperature control precision, film adhesion stability, weather resistance and the like, and the requirements of modern industry on continuous and intelligent production of high-quality coated glass are difficult to meet. Therefore, it is needed to provide a novel glass production coating curing device to solve the above problems and improve the coating efficiency and the quality of the finished product. Disclosure of utility model The utility model aims to solve the problems of high energy consumption, insufficient temperature control precision, unstable film adhesion, poor weather resistance and the like of the existing glass coating and curing device, and provides a glass production coating and curing device which is simple in structure, convenient to operate and excellent in performance.
