This utility model discloses a heated dispensing device and an automatic food vending machine, relating to the field of automatic vending machine technology. In the heated dispensing device, the heated tray is driven by a tray drive mechanism to close or open the heating chamber based on a tray transmission mechanism. The tray transmission mechanism includes a tray transmission base plate, a scissor mechanism, and a tray transmission base plate connected in sequence. The tray transmission base plate is fixedly connected to the inner bottom of the heating chamber. The heated tray is mounted on the tray transmission base plate. The scissor mechanism is driven by the tray drive mechanism to open or close, and the tray transmission base plate is driven by the scissor mechanism to rise or fall. The heated dispensing device of this utility model uses a tray transmission mechanism with a scissor mechanism as its core to cooperate with the tray drive mechanism to realize the lifting and lowering of the heated tray. This results in better reliability and higher stability, ensuring that the heated tray can operate smoothly without tilting or jamming, thereby accurately closing or opening the heating chamber and improving the usability of the equipment.

This invention relates to the technical field of stand-on reach trucks, specifically an automatic control system for a stand-on reach truck. It includes a frame, a drive mechanism, and a control system. A pair of load-bearing wheel assemblies are mounted on a pair of front legs of the frame.
