Bill transmission channel device

A banknote conveying channel device, the device being arranged between an upper machine interior for banknote identification and banknote sorting and a lower machine interior for banknote storage, and being adapted to convey, with redirection, and to separate banknotes, and the device comprising:

• a channel support, adapted to be mounted with a banknote conveying channel;
• a conveying belt, tensioned on a drive shaft and adapted to convey a banknote;
• a channel board, arranged on the channel support and comprising an upper channel board and a lower channel board, wherein:
• a banknote conveying path is formed between the upper channel board and the lower channel board,
• the conveying belt is sandwiched between the upper channel board and the lower channel board, and
• the banknote is conveyed by the conveying belt in the path formed by the upper channel board and the lower channel board;
• at least one auxiliary conveying wheel set arranged on the channel support and adapted to cooperate with the conveying belt for power transmission;
• and
• a redirection guiding plate arranged at an end of the banknote conveying channel device where the banknote enters and forming a banknote redirection path with the conveying belt;
• wherein,
• at least one floating wheel is arranged in the redirection path, the at least one floating wheel is fitted with the drive shaft of the conveying belt such that the conveying belt is sandwiched between the at least one floating wheel and the drive shaft, and the at least one floating wheel and the conveying belt form a rolling friction-based assembly;
• at least two cash boxes are arranged in the lower machine interior, the lower channel board comprises independent boards corresponding to the cash boxes respectively, gaps between the independent boards correspond to bank note entrances/exits of the cash boxes, and a redirection mechanism is arranged at each of the gaps for changing the direction of the banknote and guiding the banknote to enter/exit the cash boxes;
• an end of each of the independent boards that is close to the redirection mechanism is pivoted to the channel support, and the other end is connected to the channel support via a spring.
