[0028] The present invention uses a dough mixer to knead dough. The kneaded dough is placed on a dough conveyor and transported to a dough rolling and lifting machine. After being rolled once by the dough rolling and lifting machine, the dough enters an intermediate roller. The dough is transported through the intermediate roller for secondary rolling. After the rolling is completed, it reaches a lifting conveyor. The dough that has been rolled twice becomes a square dough sheet with a certain thickness and width. The lifting conveyor transports the dough sheet to a conveying and cutting device. An optoelectronic switch is provided on the conveying and cutting device. When it detects that the dough sheet reaches the specified position, the conveyor belt stops transporting, and the dough sheet cutting knife starts cutting. The conveyor belt transports a certain distance again. At this time, the counting gear starts to rotate, and the counting optoelectronic switch starts to record the number of teeth rotated. When the set value is reached, the counting gear stops rotating, so that the conveyor belt stops transporting. The previous dough sheet falls onto the dough sheet conveying rack, and the width of the next dough sheet to be cut is the width of the distance transported by the conveyor belt. And so on, the conveying and cutting device evenly divides the dough sheet. The dough sheets that fall onto the dough sheet conveying rack are respectively transported to both ends of the dough sheet conveying rack. Both sides of the conveying and cutting device are equipped with a steamed bun forming machine and a steamed bun shaping machine. The equally sized dough sheets enter the steamed bun forming machine for processing and forming, forming uniformly sized round steamed bun blanks, and then enter the steamed bun shaping machine for shaping and sizing, forming steamed buns with an equally sized and uniform cylindrical shape. The present invention shortens the production process of steamed buns, improves work efficiency, and has a high degree of automation.

[0029] The present invention sets up a double-line steamed bun production conveying and cutting system to evenly cut and effectively transport the dough. From dough kneading to steamed bun forming, almost no manual operation by workers is required, with a high degree of automation. And by setting up two production lines for operation, it greatly improves the production efficiency of steamed buns, reduces the work intensity of workers, and reduces the contact between workers' hands and the dough. On the one hand, it improves the hygiene standard, and on the other hand, it liberates manpower and improves the automation degree of the equipment.
