Description

Technical Field

[0002] Purple clay teapots are traditional Chinese handmade clay handicrafts. With the improvement of people's living standards and the increasing emphasis on traditional culture, the market demand is constantly increasing, and consumers also have higher requirements for the quality and output of purple clay teapots. In the traditional production of purple clay teapots, the production of clay slices mostly relies on the method of manual slapping. With the continuous development of the times, the influx of mechanized technologies has gradually provided technical support for the production process of purple clay teapots, but there are still certain defects in the production technology.

[0003] Therefore, the patent of the invention with the application number 201721792491.3 discloses a tablet press for producing purple clay teapots. By improving the two - stage processing of the roll - pressing mechanism, the flat press and the processing table, the thickness of the pressed clay slices is uniform. The processing table rotates intermittently through the action of the driving wheel and the driven wheel to provide sufficient time for processing, feeding and taking materials, so that the new structure is reliable, the operation is simple, and the practicability is strong. However, the applicant still found that there are deficiencies in the existing technology: the degree of automation of the tablet press is relatively low, and manual feeding and quantity control operations are required, which not only increases the labor intensity, but also easily leads to unstable product quality due to human factors, unable to uniformly control the quantity, and the production efficiency is not high.
