Continuous ceramic powder prepressing roller forming machine

Abstract

The invention discloses a continuous ceramic powder prepressing roller forming machine which comprises a machine body, an upper conveying device, a lower conveying device, a plurality of pairs of compression rollers and a driving device, wherein the machine body is divided into a feeding hole, a nipping prepressing area, a real pressing area, a controllable expansion area and a discharging hole. The continuous ceramic powder prepressing roller forming machine, disclosed by the invention, is short in amount of rest and high in green body strength, is placed on the front side of an automatic hydraulic press, continuously prepresses distributed powder into an initial green body and then cuts the initial green body according to the production requirements, the cut initial green body is fed into a press die cavity, and at the moment, the demanded finished blank for production can be obtained by compressing the green body once. The blank forming manner greatly reduces the working chill time, and the formed blank is high in strength and rate of finished products.

Description

technical field [0001] The invention relates to the field of mechanical equipment for producing ceramic tiles, in particular to a ceramic powder continuous pre-pressing roll forming machine. Background technique [0002] The existing ceramic wall and floor tiles are mainly formed by molding ceramic powder through a fully automatic hydraulic press. The pressing process is: mold lowering—grid cloth—moving beam lowering—primary pressurization—primary exhaust—secondary pressurization —Secondary exhaust—Three pressurization—Moving beam rise—Mould rise—Push bricks. Some products even need three exhausts and four pressurizations. The density is not uniform, the strength is not enough, and it is easy to break, delaminate, crack and other quality defects. Contents of the invention [0003] The purpose of the present invention is to propose a ceramic powder continuous pre-compression roll forming machine in order to solve the above problems. [0004] In order to achieve this goal,...
