Continuous ceramic tile digital printing decoration system and printing method

Abstract

The invention relates to a continuous ceramic tile printing decoration system. The system comprises a first conveying device used for conveying ceramic tile green bodies to be printed and a material distribution system arranged above the first conveying device. The first distribution system comprises a material distribution device arranged above the first conveying device, a second conveying device used for conveying to-be-printed powder and a storage device used for storing the to-be-printed powder. The material distribution device comprises a main body plate, a discharging unit penetrating through the main body plate and a control unit for controlling the discharging unit to discharge or not. The material distribution device is arranged below an outlet of the second conveying device, andthe to-be-printed powder conveyed by the second conveying device falls off from the second conveying device at a preset speed and is printed to the ceramic tile green bodies to be printed through thedischarging unit. By implementing the system, the to-be-printed powder can be endowed with an initial speed, so that the speed of the to-be-printed powder passing through the material distribution device is greatly increased, and the printing speed is increased.

Description

technical field [0001] The invention relates to the technical field of ceramic tile equipment and production methods, in particular to a continuous ceramic tile digital printing decoration system and printing method. Background technique [0002] With the improvement of people's aesthetic level, the requirements for the decorative effect of ceramic tiles are also constantly increasing. The traditional primary distribution machine and secondary distribution machine have been difficult to meet the distribution requirements of ceramic tiles. For this reason, the inventor proposed a patent application (201910374027.X) for a digital printing device and digital printing method, see figure 1 , a plurality of outlets are set at the bottom of the silo 1, and the opening and closing of the outlets are controlled by the gate 31 and the controller 32, so as to realize the precise discharge of the powder and obtain a good printing decoration effect. Moreover, in this invention, a materi...
