Background

The pottery jar industry is the traditional characteristic industry of China, has a very long history and is an important symbol of the traditional culture of China. The glazing link is an important link in the process of manufacturing the pottery jar, and the quality of the pottery jar is determined by the quality of the glazing to a certain extent. The glazing process has the significance that the glazing process can well protect the materials in the pottery jar from being influenced by the external environment, and meanwhile, the pottery glaze can cover certain flaws on the pottery jar blank, endows the blank with rich colors, can improve the appearance and has a good decoration effect. Along with the annual increase of the demand of the wine making market for high-end white spirit pottery jars, the requirements on the quality and the efficiency of white spirit pottery jar processing are higher and higher, in the production process of the pottery jars, glaze spraying is a necessary process, but the glaze spraying process of the white spirit pottery jars still adopts a manual mode at present, the efficiency is low, the quality is difficult to meet the requirement of high-end white spirit storage, and the research and development of efficient, stable and controllable automatic glaze spraying equipment is urgently needed. The manual glazing method comprises the following steps: under the condition of stirring, a certain pressure is applied to press the glaze slurry into a hand sprayer from a pipeline, and the pressure compressed air in the spray gun is utilized to press out the glaze slurry and spray the glaze slurry onto a green body. The glaze slip loses part of its water content during the glazing process, and the dried body quickly absorbs the water content of the glaze slip just sprayed onto the surface. The manual glazing mainly has the following problems: the production management is difficult, the efficiency is low, and the product quality stability is poor due to uneven technical level of workers, uneven thickness of a pottery jar glaze layer and uneven glaze material. The rejection rate is higher, and the raw material consumption and the product cost are increased. The conditions of the production workshop are poor, the dust in the production environment is large, the noise is high, and the pollution is serious.
