Pickup device for a self-service printing vending machine

Abstract

This invention discloses a self-service printing vending machine dispensing device, comprising a fixed plate, a moving motor, a negative pressure pump, a movable plate, two pulleys, a transmission belt, a connecting frame, a limiting slide rail, a protective mechanism, a connecting pipe, four negative pressure suction cups, and a buffer mechanism. The moving motor and the negative pressure pump are fixedly connected to the upper end of the fixed plate. The output end of the negative pressure pump is provided with the protective mechanism, and the connecting pipe is provided on the protective mechanism. One side of the transmission belt is fixedly connected to the connecting frame, and the connecting frame is fixedly connected to the movable plate. The four negative pressure suction cups are provided at the lower end of the movable plate. The buffer mechanism is provided between the four negative pressure suction cups and the movable plate. The buffer mechanism effectively offsets the impact force generated when the suction cups come into contact with the printing fixture, avoiding scratches or damage to the fixture surface, and preventing the negative pressure suction cups from warping after long-term use. It ensures that the negative pressure suction cups and the fixture are always in close contact, reducing air leakage problems, thereby improving adsorption stability and reducing the dispensing failure rate.
