Method and equipment for preparing green tiles of ceramic tiles

Abstract

In the invention, a method and equipment for preparing green tiles are improved in both material distribution and green tile transfer. In material distribution, a powder output device directly spread powder on a working face of a mold core at a uniform flow rate, and while the powder is spread, the output end of the powder output device is moved at a constant speed in a direction parallel to the working face of the mold core; and in green tile transfer, an absorption device absorbs the green tiles upwards, but not make the green tiles leave the supporting face of the green tiles, so that the green tiles are supported by the supporting face all the time in a transfer process. The method and the equipment can meet the requirements for preparing the green tiles of the ceramic tiles, and compared with the prior art in which a traction belt passes through a mold, have the advantages of solving the problems such as the short service life of the traction belt, avoiding the reconstruction of the internal structure of a hydraulic machine and making the implementation easy. In addition, the method and the equipment are suitable for preparing thinner green tiles and thick common green tiles, improve the utilization rate of the equipment and reduce the production cost.

Description

technical field [0001] The invention relates to the manufacturing technology of ceramic bricks, in particular to a method and equipment for preparing adobe of ceramic thin bricks. Background technique [0002] The adobe preparation method of ceramic tiles mainly includes three steps of distributing, pressing and transferring. Through these three steps, the process of pressing the ceramic powder into adobe and taking out the adobe from the mold is completed. However, traditional adobe preparation methods and equipment cannot be directly used to prepare adobes of thin ceramic tiles, such as adobes of thin ceramic tiles with a thickness less than 6mm. Because the traditional adobe preparation method has defects in the cloth and adobe transfer process, it cannot meet the requirements for making ceramic thin adobe bodies. [0003] For example, in the process of fabric distribution, the traditional brick preparation method first uses a powder output device to lay a layer of powd...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this method is that the mold frame and the mold core cannot be completely matched, and the powder must be sandwiched between the mold frame and the mold core. Therefore, this method can only be used to prepare thin bricks, and cannot be used to prepare ordinary ceramics with a large thickness. brick adobe, low utilization rate of equipment, increased production cost, and the biggest disadvantage of this method is that the traction belt must bear the pressure of the hydraulic press, the service life is short, and it needs to be replaced frequently, which reduces production efficiency and increases production cost

Furthermore, the traction belt passes between the mold frame and the mold core, which increases the complexity of the hydraulic press structure

Furthermore, due to being blocked by the traction belt, the mold frame can only be lifted upwards after the pressing is completed, which is easy to damage the edge of the adobe and reduces the yield
