Automatic glazing method for ceramic bowl blank

Abstract

The invention discloses an automatic glazing method on a domestic ceramic bowl blank surface. Glaze slip is sprayed in the forward motion and rotation process of the blank, the glaze is uniformly coated on the blank surface under the centrifugal force generated by the rotation of the blank, and meanwhile, excessive glaze slip is thrown out from the edge of the blank and collected for cyclic use. The invention can be matched with a large-scale production line, and can be used for small-scale workroom production. The invention overcomes the defects of cracking, bubbling, waving and the like caused by improper operation and other reasons in the artificial glazing process. The blank produced in the mode of glaze slip spraying in the rotation process has the advantages of no waving, uniform glazing and smooth glaze surface; and the invention greatly enhances the production efficiency, and can not generate pollution capable of obviously hurting the human body in the production process.

Description

technical field [0001] The invention relates to a method for glazing a bowl body, in particular to a method for automatically glazing the surface of a daily ceramic bowl body. Background technique [0002] In the industrial production of daily-use porcelain, after the raw material mud is pressed and formed, a layer of glaze must be evenly coated on the surface of the blank and then fired to form a finished product. There are three methods of glazing traditional daily-use porcelain: [0003] ①The method of manual glazing is completely adopted, and no protective measures are taken by hand. According to special requirements, the blank is directly immersed in the glaze pool and taken out. It is not only used for one-time glazing of daily-use porcelain and other small ceramic products, but also generally used for external glazing of larger ceramic products such as pots, bottles, cups, jars, and figurines. This method requires the operator to be proficient in technique, uniform ...

AI Technical Summary

Problems solved by technology

This method can be used for some thin-walled and fragile high-grade products, bisque-fired blanks, underglaze decorated products and some large porcelain plates. It has high automation, but it is not suitable for those with large inclination angles. The production of ceramics is very polluting. The mist particles in the glaze spraying process are exposed to the air to waste a lot of glaze, which is difficult to recycle and has obvious harm to the human body. Baffles and dust collection facilities must be installed in the production line and workshop

Therefore, this production method requires high investment in plant construction and equipment, and is suitable for some large-scale production enterprises or the production of some high-end ceramic products, and cannot be directly applied to the daily-use porcelain industry on a large scale.
