The roll printing biscuit forming machine is used for the roll printing of crisp biscuits. It accepts the dough that has been mixed by the flour mixing machine, and the biscuits of various shapes formed by the roll printing are spoiled. The machine is simple in structure. The separating knife is equipped with an adjustable device, which can be adjusted to the best position. The roller printing roller is specially designed to overcome the uneven wear of the separating knife. Both sides of the demoulding pressure roll can be adjusted, which has the advantages of easy mold change and high yield. The vertical roll printing machine can be assembled on the roll cutting machine without affecting the normal production of the roll cutting machine.
