[0002] The puffing machine is a kind of equipment for processing puffed food, such as rice, corn, soybean, wheat, etc. in daily life. Its main working principle is to convert mechanical energy into thermal energy, and use the heat generated by the rotation of the machine to squeeze and cook the food. The most obvious feature of the puffed food is that the volume becomes larger. Then, the puffed food is shaped, twisted, and cut by the auxiliary forming mechanism set near the discharge port to finally form a finished product that can be sold.

[0003] In order to realize automatic operation during the operation of the extruder, a cutter is usually arranged in front of the discharging head to cut the continuously produced extruded food into small pieces for easy storage and consumption. However, in order to ensure that the cut food has the same size, the shaft driving the cutter is usually connected to the main shaft of the machine for producing food by a gear or a transmission shaft to ensure that they move at the same angular velocity. Although this ensures that the cut food has the same length, the fixed blade and the fixed rotation speed make it impossible to produce products of other length sizes. After searching, it was found that the technical solution provided by the utility model with application number CN201420253298.2 also has the above-mentioned problems. Utility Model Content
