By setting the side wall pick-and-place device, the side wall can be automatically picked and placed through the side wall pick-and-place device. The side wall is independently transported on the side wall conveyor line for optimization. The process of feeding and discharging products improves production efficiency.

3. The side panel pick-and-place device uses a vacuum pump to generate negative pressure, so that the annular suction cup and the side panel are mutually adsorbed by negative pressure, which facilitates the overall transfer of all side panels that form the cavity of the mold, and also realizes that the vacuum pump does not produce negative pressure. When pressing, place all the side panels as a whole to reduce the possibility of disassembly and reassembly of each side panel one by one, which is beneficial to improve production efficiency and maintain product consistency.

4. Because the foamed ceramic is semi-solid and fluid when it is sintered at high temperature, the shed cleaning device removes the residual foamed ceramic residue on the surface of the shed through the cleaning head, and absorbs the cleaned residue through a vacuum cleaner Removal, so as to clean the slats and reduce the occurrence of pulp leakage due to damage to the fiber paper due to the uncleaned residues of the slats.

6. Based on the improved production system, when using the production system, after the kiln furniture is placed in the product and before the cloth, the slab is cleaned twice to reduce the residue and the dirt falling on the slab during the conveying process. Maintain the reliability and stability of the production process.
