The invention relates to the technical field of vending machines, and discloses a material jam preventing device of a beverage vending
machine. The material jam preventing device comprises a main body, wherein a selling cavity and a falling cavity are formed in the inner side of the main body, the selling cavity is positioned above the falling cavity, a semicircular
pickup groove is formed in thebottom part of the falling cavity, and a sliding plate and a mounting plate are welded to the inner side of the selling cavity. According to the material jam preventing device of the beverage vendingmachine, a turntable is installed below a
material storage pipe, when in use, a corresponding position is selected according to samples displayed on the front surface of the turntable; the turntable is controlled to rotate anticlockwise by means of an output shaft, beverage in the
material storage pipe falls into an outer groove of the turntable, the turntable continues to rotate to transfer the beverage onto a sliding plate, the beverage falls onto the buffer plate by means of the inclined sliding plate and finally falls into the
pickup groove by means of a guide plate, so that the beverage is flatly placed, the beverage rolls down by means of the inclined sliding plate, and the problems that the beverage is clamped in the falling process, the
consumer cannot take commodities and sufferseconomic losses are prevented.
