Description

Money Collecting Machine

This invention is related to the technical field of banknote collecting machines, and in particular to a banknote collecting machine in which a guide roller is pushed by a compression spring to maintain an abutment state.

Automatic payment machines are currently widely installed in various places where fees are collected, such as parking lots or vending machines for various products. Automatic payment machines are equipped with a banknote acceptor for accepting paper bills when users pay in cash.

In addition to the bill conveying mechanism for conveying paper bills from the bill inlet to the bill outlet, the existing bill collecting machine also has a pair of guide rollers near the bill outlet, which clamp the paper bills and convey them to the bill outlet. However, after long-term use, the guide rollers are worn, resulting in a gap between the two guide rollers, which cannot generate sufficient clamping force for the paper bills. As a result, the paper bills are easily squeezed and jammed before the bill outlet.

In addition, some bill collectors will be equipped with multiple torsion springs at the bill outlet to abut against the shaft sleeve of the guide rollers so that the two guide rollers maintain an abutting state to maintain the clamping force of the two guide rollers on the paper bills. However, since torsion springs are not easy to install on the bill collector and the cost of torsion springs is relatively high, only a small number of bill collectors will use torsion springs, and most bill collectors will still have the problem that paper bills are easily squeezed and jammed before the bill outlet.

In view of this, the purpose of the present invention is to provide a bill collecting machine, which solves the problem that the guide roller of the prior art cannot reliably clamp the paper bill due to gaps caused by wear after long-term use, and also solves the cost and difficulty in installation caused by the use of torsion springs in the prior art.
