Method for detecting blank filling uniformity of ceramic tile green body

Abstract

The invention discloses a method for detecting blank filling uniformity of ceramic tile green bodies. The method comprises the following steps of S1) taking N ceramic tile green bodies pressed in the same batch by the same mold, N being greater than or equal to 3, and sequentially arranging the N ceramic tile green bodies into a longitudinal row from front to back along the running direction of a ceramic tile kiln; S2) measuring and recording the pre-firing length from the A1 edge to the AN edge of the N ceramic green bricks; S3) starting a kiln to fire the N ceramic green bricks, and measuring the length of the N ceramic green bricks after firing from the A1 side to the AN side; S4) calculating to obtain a length difference value between the A1 edge and the AN edge of the N ceramic green bricks before and after firing; and S5) arranging the N size shrinkage values according to the arrangement sequence of the N ceramic tile blanks before firing so as to generate a distribution diagram for representing blank filling uniformity of the ceramic tile green bodies. The operation method is simple and easy, can be used for distinguishing and screening defective green bricks, and can improve working efficiency of detection.

Description

technical field [0001] The invention belongs to the technical field of ceramic tile production, and in particular relates to a method for detecting the filling uniformity of a ceramic tile green body. Background technique [0002] Existing ceramic tiles are usually compressed by raw material granules produced by dry granulation and powder making process. The raw material granules prepared by dry granulation and powder making process have difficult control of particle gradation, small particle compression rate, and particle flow. The problem of sexual deviation, after using the press machine to distribute the blanks to press the green ceramic tiles, if the filling uniformity of the blanks in the horizontal and vertical directions of the green ceramic tiles is poor, it is easy to cause batch deformation and deformation of the green ceramic tiles in the subsequent firing process. Cracking defects, serious loss of quality. [0003] The same mould, especially the ceramic brick a...

[0002] Existing ceramic tiles are usually compressed by raw material granules produced by dry granulation and powder making process. The raw material granules prepared by dry granulation and powder making process have difficult control of particle gradation, small particle compression rate, and particle flow. The problem of sexual deviation, after using the press machine to distribute the blanks to press the green ceramic tiles, if the filling uniformity of the blanks in the horizontal and vertical directions of the green ceramic tiles is poor, it is easy to cause batch deformation and deformation of the green ceramic tiles in the subsequent firing process. Cracking defect, serious loss of quality

[0003] The same mould, especially the ceramic brick adobe pressed from different cavities of the same mould, has a large difference in the filling uniformity of the adobe, but if the difference is observed and found with the naked eye, the workload is large, the efficiency is poor, and errors and errors are prone to occur. missed detection
