The billet storage machine is an auxiliary equipment for feeding green blanks into the firing kiln. The feeding of green blanks into the firing kiln must be continuous, which is a key factor in reducing the color difference of the finished products. The billet storage machine determines the length, width, height and number of layers according to the product specifications and output, and the number of units is determined according to the process requirements of the product. It is an indispensable auxiliary equipment for production continuity and stability. According to the output size, two-column and four-column modes can be adopted. The main lifting chain has two columns for each column for the most stable effect. The number of stored blanks must match the process conversion of the glazing line. The electronic control is controlled in sections by the PLC program to link the upper and lower processes.
