The working principle of this disc coin sorting machine is as follows:

The disc type coin sorting machine has two powers, one is input by the first motor 7 to drive the rotating tray 17 fixed on the first motor; the other power is input by the second motor 9, and the second motor 9 drives the rotating tray 17 fixed on the first motor. The small gear 13 on the second motor 9 drives the large gear 12 meshed with the small gear 13 to rotate, and the coin sorting plate 14 fixed with the large gear 12 rotates together. The rotation directions of the rotating tray 17 and the coin sorting tray 14 are opposite. Place the coins to be sorted on the rotating tray 17. The coins will move centrifugally under the action of the centripetal force generated by the rotation of the rotating tray 17. Coins that stand up or are stacked on top of other coins will be blocked by the guide plate 15, while the coins that are flat will be blocked by the guide plate 15. The coins placed on the rotating tray will enter directly below the guide plate from the gap between the lower surface of the guide plate and the upper surface of the rotating tray. At this time, these coins are still on the rotating tray and will move in a circle with the rotating tray. , so under the dual action of the guide channel on the lower surface of the guide plate and the rotating tray, the coins will come out of the exit of the guide channel that only allows one coin to pass, move to the pallet, and be located on the coin sorting plate 14 In the annular guide groove, when the spring piece 18 rotates with the coin sorting plate 14 and touches the coins, it will push the coins to rotate together with the coin sorting plate 14 (when the coins are not completely thrown out from the exit of the guide channel, When the spring leaf rotates to touch the coin, it will deform, and the coin may return to the guide groove, or may be pushed out by the spring leaf), because the width limit of the annular guide groove cannot accommodate two coins at the same time, and the coins in the annular guide groove will It prevents the next coin from coming out. Therefore, there is at most one coin between the two spring pieces 18. When the coin rotates with the coin sorting plate, it will be close to the side wall of the coin sorting slot that fixes the spring piece, so when the coin follows the coin Under the action of the centrifugal force generated by the rotation of the sorting plate 14, the coins will enter the coin sorting slot that is narrowed in a stepped manner. Since coins of different denominations have different diameters, the coins of different denominations entering the coin sorting slot will be stuck in the coin sorting slot. At different positions of the coin sorting tray, when the coins move with the coin sorting tray 14 to the one dollar coin fan annular notch, nickel coin fan annular notch or dime coin fan annular notch position of the supporting plate 16, they will be removed from the supporting plate 16. It falls onto the coin chute 2, and then passes through the funnel 6 and falls into the coin collection tube of the corresponding face value. The coin collection status can be seen from the gaps on the sides of each coin collection tube. When the coins are full, the coin collection tube is removed; the number of coins can be directly read from the scale on the coin collection tube.
