[0003] The existing product discharging mechanism allows the product to slide to the medicine dispensing port through an inclined slide. For example, a Chinese utility model patent discloses a combination vending machine for medicines and medical devices (CN202122360165.8), which moves the hopper in the vertical direction through a vertical conveying mechanism. The hopper is an inclined structure, and the lower end of the hopper slides against the vertical upright plate. When the hopper passes over the upright plate or moves to the opening position of the upright plate, the medicine slides from the hopper in the inclined structure into the slide, and then the medicine slides from the slide to the medicine dispensing port. The hopper can only move up and down along the upright plate, which means that one hopper can only correspond to one slide. When multiple dispensing ports are set, multiple hoppers and slides are required, resulting in a bloated and complicated equipment structure. Utility Model Content

The angle between the bottom plate 4 and the bending plate 40 is an obtuse angle, and the angle between the bottom plate 4 and the bending plate 40 is facing upward. When transporting products, the bottom plate 4 of the bottom plate 4 tilts downward to the rear side, and the bending plate 40 of the bottom plate 4 tilts downward to the front side. At this time, the products slide and gather toward the position where the bottom plate 4 and the bending plate 40 are connected, which effectively prevents the products from falling out of the discharge plate 3. A driving mechanism for driving the bottom plate 4 to flip is provided on the discharge plate 3, and the driving mechanism includes a motor 5, a transmission rod 50 and a connecting rod 51. The top surface of the connecting rod 51 is connected to the bottom surface of the bottom plate 4, and the axis of the connecting rod 51 is parallel to the bottom plate 4.
