Terrine machine

Technical Field

The invention belongs to the technical field of ceramic processing equipment, and particularly relates to a pottery pot overturning machine.

Background

The pottery jar is a pottery container made of ceramics for containing liquid or food. In the production process of the pottery pot, an important process is provided, namely, the pottery pot green body is roasted to ensure that the pottery pot is gradually dehydrated and hardened to have certain hardness and can keep a stable shape, and the pottery pot is fired after being hardened to ensure that the pottery pot is subjected to biochemical reaction under the specific condition of high temperature to finally become the pottery pot with fixed volume and specific performance.

The firing of the crockery is usually carried out in a kiln, and before the crockery enters the kiln for firing, two crockery are sometimes needed to be placed in a way of being aligned with each other in order to fully utilize the space, so that a part of the crockery needs to be turned over by 180 degrees. The prior art needs to use the purlin car to lift the gallipot and then turn over, so a special lifting appliance needs to be used, and the lifting appliance needs to be repeatedly lifted in the turning process, which is very troublesome.
