Single card separation apparatus and card distribution device

A card dispensing device, comprising:

• a device for separating cards in single sheets, which comprises a support frame, a driving shaft movably mounted on the support frame, and a separating wheel provided on the driving shaft;
• wherein, the driving shaft is movable freely up and down on the support frame;
• an elastic component is provided between the driving shaft and the support frame;
• and
• the elastic component has one end fixed to the support frame and another end mounted on the driving shaft, which allows the separating wheel to always keep a downward pressure to cards stacked on the card dispensing device under the action of an elastic force;
• and
• the separating wheel is driven by rotation of the driving shaft, and a relative rotational gap with a preset angle range exists between the separating wheel and the driving shaft;
• and the support frame is provided with a vertical elongated slot in which the driving shaft is moved up and down;
• wherein the device for separating cards in single sheets comprises the support frame, the separating wheel, the driving shaft and the elastic component;
• and
• a transmission mechanism comprising an upper position-limiting component and a lower position-limiting component which are mounted on the support frame;
• wherein the upper position-limiting component and the lower position-limiting component are vertically opposite to each other, and a card dispensing gap which is larger than a thickness of a single card and smaller than a thickness of two cards is defined between the upper position-limiting component and the lower position-limiting component;
• and
• wherein the upper position-limiting component is fixedly mounted on the support frame, and the lower position-limiting component is movably mounted on the support frame.
