Description

Technical Field

[0001] The present application relates to the technical field of coin packaging, and more specifically, to a mechanical structure of a coin circulation conveying channel in a fully automatic coin sorting and packaging machine. Background Art

[0002] At present, it is an inevitable trend for coins to occupy the small currency market worldwide with their irreplaceable advantages such as low cost, high circulation frequency, wear resistance and easy recycling. As the frequency of coin use gradually increases, the separation and packaging of coins has become an issue that society is paying more and more attention to.

[0003] In the coin packaging machine in the prior art, there is only one main channel with adjustable width and one rejected coin channel. When working, the width of the main channel can only be adjusted in order from wide to narrow to realize the transmission of coins. During the transmission process, suspicious coins and coins with small diameters can enter the rejected coin storage box from the rejected coin channel, and only coins with large diameters are subjected to subsequent packaging processes along the main channel.

[0004] In addition, if small-diameter coins in a rejected coin storage box are to be packaged, the operator needs to first pick out the large-diameter suspicious coins, then put the remaining coins into the coin slot of the packaging machine, and start the packaging machine again for packaging; if small-diameter coins are selected for packaging first among mixed coins with coins of different diameters, the packaging machine will malfunction. The efficiency of coin packaging machines in the prior art needs to be improved.

[0005] Therefore, how to provide a mechanical structure of a coin circulation conveying channel in a fully automatic coin sorting and packaging machine, which can be applied to the coin packaging machine to improve the packaging efficiency and automation level of the coin packaging machine, has become a technical problem that needs to be urgently solved by technical personnel in this field.
