Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The present invention discloses a precision pressing control method for a ceramic tile press. Firstly, it realizes remote control of the tile press by introducing a programmable logic controller (PLC) and a secondary network connection into the tile press. The public patent document CN103412524A constructs a set of digital production management system for brick-making enterprises based on network connection, which can remotely control the brick-making factory equipment through the remote network by the central industrial computer, which can effectively solve the current manufacturing equipment and technology. Large, and at the same time, equipment maintenance is also more difficult. For the control of the brick press, it can also build a network connection, send the PLC program of the tile pressing process to the brick press fr...

Abstract

The invention discloses a ceramic tile press precise pressing control method. According to the method, a PLC program is formed by a pressing technology and written into a tile press control program before tile blanks are pressed, therefore, the speed of a movable beam and an upper mold core and pressing parameters such as the pressing force and the pressing time can be controlled by a PLC more precisely, movement of the movable beam and the upper mold core is in a parabolic trend, and lifting is smoother; the upper mold core can adopt two times of pressing operation under the low-pressure pressing force and one time of pressure maintaining operation under the high-pressure pressing force, and precise pressing of the tile blanks is achieved; the stricter pressing requirements of large-sizeceramic tiles and ultrathin ceramic tiles can be met through precise pressing of the tile blanks, and size errors generated due to the fact that powder is impacted to escapes in the descending processof the upper mold core are reduced; and in addition, the pressure uniformity can be improved, and the strength and the compactness of the ceramic tile blanks are improved.

Description

technical field [0001] The invention relates to the technical control field of brick adobe pressed by a brick press, in particular to a precise pressing control method of a ceramic brick press. Background technique [0002] Ceramic tile is the most common building material in the construction industry, which is obtained by pressing ceramic powder and surface processing. Ceramic powder is generally pressurized by a brick press to form bricks, and then the bricks are dried, glazed, and finally fired to obtain our daily ceramic tiles. [0003] In the tile manufacturing process, whether the tile press can work normally is the key to the normal production of the porcelain factory. The tile press is the most important equipment in the construction ceramics production industry. At present, the main types of tile presses used in the domestic construction ceramics industry to produce tiles are open type Hydraulic brick press, closed hydraulic brick press and first-class steel wire w...
