Canteen dish selling device

The utility model provides a canteen dish selling device, which comprises a first lifting branched chain, a second lifting branched chain, a tray frame, a selection disc, a fee register and an LED display lamp. Each lifting branched chain is composed of a driving lever and a connecting rod, wherein the driving lever is driven by a servo motor to rotate so as to drive the connecting rod to move, and then control the lifting process of the tray frame. The selection disc is adopted as the input unit of the fee register. A single-chip microcomputer is adopted as the control core of the fee register. By means of the canteen dish selling device, dishes can be order outside a window, and then the total amount of ordered dishes is automatically calculated. Meanwhile, the tray frame can automatically go up and down. Therefore, the dish serving efficiency is improved and the tray frame can be conveniently cleaned and stored for a long time. The dish pollution degree during the dish serving process of students is further reduced. Meanwhile, the mental labor and the manual labor of aunts in a canteen are reduced at the same time. Compared with an existing canteen dish serving device, the above device is more practical and more sanitary, and can be applied in not only modern school canteens but also in fast food restaurants.
