Dumpling wrapper production device capable of freely switching specifications and sizes for food processing

The dumpling wrapper production device comprises a main body box, wherein a transmission belt cavity with a leftward opening is formed in the main body box, a grinding tool switching cavity is formedin the upper end wall of the transmission belt cavity in a communicating mode, and a grinding tool friction wheel cavity is formed in a front end wall of the grinding tool switching cavity in a communicating mode; by rotating the grinding tool switching knob, the grinding tool switching box provided with grinding tool rollers of different specifications is driven to rotate, so a more convenient dumpling wrapper grinding tool roller switching mode is realized, production efficiency of dumpling wrappers is improved, labor intensity of workers is reduced, and working efficiency of the workers isimproved; meanwhile, by rotating the thickness adjusting knob, production thickness of the dumpling wrappers can be freely adjusted, and the flour box is driven by the vibration block to continuouslyvibrate, so the flour can b
