To save manpower and reduce workers' labor intensity, our factory has developed a hydraulic automatic board stacking and dropping machine. This machine features simple operation and stable operation, adapting to the use of various sizes of blank boards. The hydraulic board dropping system has a gentle dropping speed, which plays a good role in improving the quality of brick blanks, keeping the brick blanks from deforming. Moreover, a board returning system is installed on the upper part to prevent the blank boards from deforming, and it can send the returned empty boards back to the blank cutting table, reducing the damage of blank boards.
