Namely, the PLC8 control flow is as follows:

STEP 1: manually filling reed leaves → finishing filling → rotating the rotating shaft by 90 degrees;

STEP 2: the valve 7 of the first filling barrel 601 is opened → 25 g of glutinous rice is filled → the first filling barrel 601 is closed → the rotating shaft rotates 90 degrees;

STEP 3: the valve 7 of the second stuffing barrel 602 is opened → stuffing is filled → the valve 7 of the second stuffing barrel 602 is closed → the rotating shaft rotates 90 degrees;

STEP 4: the valve 7 of the third filling barrel 603 is opened → 25 g of glutinous rice is filled → the valve 7 of the third filling barrel 603 is closed → the rotating shaft rotates 90 degrees;

STEP 5: the push rod extends out to cover the reed leaves → the cam extends out to be compacted → the wire block is twined and knotted.

In another embodiment, the size and weight of the filling are difficult to control, when the size and weight of the filling do not make an accurate requirement, only the total weight of the rice dumpling is regulated, when the last upper layer of glutinous rice is filled in the third filling barrel 603, the total weight of the rice dumpling is weighed by using the electronic scale 9, and the amount of the upper layer of glutinous rice is controlled, so that the total mass of each rice dumpling is ensured to be within an error allowable range.
