The bottom of the tile blank is coated with multiple coating rollers. The array layout of multiple coating rollers cooperates with the layered coating process of the high temperature resistant medium. Through the directional seepage design of the connecting groove, the high temperature resistant medium can be coated on the blank. A dense composite protective layer is constructed at the bottom of the material. On the one hand, it can effectively prevent the ceramic tile blank from deformation during high-temperature firing, improve the deformation resistance and penetration resistance of the ceramic tile blank, and thus improve the quality of the finished product. On the other hand, the high-temperature resistant medium forms a coating layer and cooperates with the contact block, which can effectively reduce the contact area between the roller and the ceramic tile blank, thereby avoiding adhesion between the ceramic tile blank and the roller due to high temperature, which not only ensures the smoothness of the ceramic tile blank transportation, but also avoids leaving marks on the bottom of the ceramic tile blank due to adhesion between the two, thereby improving the quality of the ceramic tile finished product.

The sealing door drives the heat-resistant air bag to expand and contract periodically through the driving racks, driving gears, second rotating shaft, driving cam, sliding plate and first spring on both sides. The heat-resistant air bag forms an airtight air curtain with the hot air in the roller furnace body through the air collecting hood, connecting pipe and flat nozzle, so as to avoid the heat loss of the roller furnace body after the sealing door is opened, and can preheat the tile blanks. Non-contact sealing is achieved through the dynamic airflow of the air curtain, which can significantly improve the temperature field stability and reduce energy consumption in the roller furnace body, and adapt to complex working conditions. The air curtain can be adaptively started through the mechanical transmission when the sealing door is opened and closed, thereby reducing energy loss.

[0017] 3. In the present invention, by setting a cooling component, the bellows is started, and the bellows conveys the cooling airflow downward through the connecting hose and the air outlet pipe. At this time, the electric push rod is started, and the electric push rod drives multiple air outlet pipes to swing back and forth around the mounting seat through the connecting sleeve, so that the spray range angle of the cooling airflow can be adjusted, so that the tile blank can be cooled in all directions, avoiding the occurrence of cooling dead corners, and improving the molding efficiency of the finished product.

[0027] The specific implementation method is as follows: the bellows 702 is started, and the bellows 702 conveys the cooling airflow downward through the connecting hose 707 and the air outlet pipe 703.

[0028] Working principle: When in use, the staff places the tile blank on the conveying mechanism 4, and starts the driving mechanism 5 to drive the coating roller 806 and the roller rod 10 to rotate.
