The invention also provides a coin exchange machine, which comprises a coin inlet and outlet, a coin storage device 100 and the coin conveying device 200; the coin transporting apparatus 200 is used to transport coins between the coin inlet and the coin storage 100.

The working principle of the coin feeding device provided by the invention is described below.

When the coin conveying device 200 normally works, the fixing wall 16 of the mounting rack 1 and the upper wall 303 of the coin box 300 are fixedly connected by the fastener, the connecting arm 45 of the engaging wrench 42 and the fixing column 17 of the mounting rack 1 are fixedly connected by the fastener, the eccentric sleeve 41 of the engaging component 4 is fixed on the first position, the first transmission piece 31 is meshed with the second transmission piece 32 and connected, the output shaft 21 of the motor 2 rotates, the transmission shaft 30 can be driven by the first transmission piece 31 and the second transmission piece 32 to rotate, the gear 331 rolls along the rack 332, and the coin box 300 is moved in the up-and-down direction.

When the coin conveying device 200 needs to be maintained, the fastening piece for fixing the clutch wrench 42 and the fastening piece for fixing the mounting frame 1 are removed, the clutch wrench 42 is rotated to enable the eccentric sleeves 41 to rotate to the second position, the two eccentric sleeves 41 drive the mounting frame 1 to rotate around the axis of the transmission shaft 30, the first transmission piece 31 is separated from the second transmission piece 32, and at the moment, the gear 331 can freely roll along the rack 332, so that the coin box 300 can be moved to the required maintenance position.

The coin conveying device 200 provided by the invention comprises a coin box 300, a motor 2, a transmission assembly 3 and a clutch assembly 4; the motor 2 drives the coin box 300 to reciprocate along a set direction through the transmission component 3; the clutch assembly 4 is used to disconnect or connect the drive connection between the motor 2 and the cassette 300. When the coin box 300 needs to be moved for maintenance of the coin conveying device 200, the clutch assembly 4 is adjusted to disconnect the transmission connection between the motor 2 and the coin box 300; when normal use of the coin conveying apparatus 200 is required, the clutch assembly 4 is adjusted to communicate the drive connection between the motor 2 and the magazine 300. Compared with the coin conveying device in the related art, the coin conveying device provided by the invention is more convenient to maintain.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
