Study And Design On The Coating And Pressure System Of Environment-Protective And Energy-Conservative Glazing Machine

This article took UVSG950 environment-protective and energy-conservative glazing machine as a research object. The coating and pressure system is deemed to be one of the important systems in the environment-protective and energy-conservative glazing machine. The design of uniformity, stability and adaptability are key techniques in the system of coating and pressure. The uniformity and leveling situation in the coating could affect the following work of solidifying,drying,coating quality,developing and the studying of the environment-protective and energy-conservative glazing machine. In this article, through studying and testing, the best coating method, the three rollers clockwise rotation coating, was chosen and the best area of pressure was chosen too. Finally the two subsystems of coating measurement and hydraulic pressure were decided.As for the subsystem of coating measurement, through analyzing the function and working elements of coating measurement, the worm couple within nut and leading screw and the scraper mechanism of three rollers clockwise rotation coating were designed and the precision of coating measurement was improved. Based on the regulating mechanism of coating measurement, the device of automatic display and feedback based on the single-chip was designed. It could offer the space of coating measurement real-time, improved the regulating method of coating measurement which depended on the experience in the past, and made regulating the space of coating roll and gauging roll easily and exactly. It provided convenience for manipulating the coating measurement.As for the pressure control mechanism, through analyzing the expression method of pressure and the factors of affecting pressure, the manual hydraulic pump was chosen to control and regulate the pressure. Combining with the demand of the system, the double-pole manual hydraulic pump was designed and it conquered the problems which existed in the eccentric cam mechanism. It made regulating pressure directly showing, well looking, and provided convenience for manipulating the pressure.
