Abstract

A banknote separation device includes a banknote separation wheel set and a reverse wheel set. The reverse wheel set includes a reverse wheel component, a reverse wheel set rotation shaft, a first fixing frame and a second fixing frame. Two ends of the reverse wheel set rotation shaft are fixed on two mounting side plates respectively, the first fixing frame and the second fixing frame are respectively fixedly connected at two ends of reverse wheel component. The first fixing frame is provided with two lash adjusting threaded holes and a first lash adjusting screw, the second fixing frame is provided with a second lash adjusting threaded hole and a second lash adjusting screw cooperating therewith, and radial clearances between two ends of the reverse wheel component and the banknote separation wheel set are adjusted respectively by the two lash adjusting screws.

First claim

The invention claimed is:

1. A banknote separating device for a financial self-service apparatus, comprising:
a banknote separating wheel set and a reverse wheel set cooperated with the banknote separating wheel set,
wherein the reverse wheel set comprises a reverse wheel component, a reverse wheel set rotating shaft, a first fixing frame, and a second fixing frame, two ends of the reverse wheel set rotating shaft are fixed respectively to two mounting side plates in the financial self-service apparatus, and the first fixing frame and the second fixing frame are respectively fixedly connected to two ends of the reverse wheel component;
wherein an end, away from the second fixing frame, of the first fixing frame is provided with a first gap adjusting threaded hole, a first gap adjustment stop block extends from the mounting side plate at a side close to the first fixing frame, and the position of the first gap adjustment stop block corresponds to the position of the first gap adjusting threaded hole, a first gap adjusting screw is arranged in the first gap adjusting threaded hole, and a head portion of the first gap adjusting screw is in contact with the first gap adjustment stop block; and
wherein the second fixing frame is provided with a second gap adjusting threaded hole, a second gap adjustment stop structure extends from an end, close to the second fixing frame, of the first fixing frame, and the position of the second gap adjustment stop structure corresponds to the position of the second gap adjusting threaded hole, a second gap adjusting screw is arranged in the second gap adjusting threaded hole, and a head portion of the second gap adjusting screw is in contact with the second gap adjustment stop structure.

2. The banknote separating device according to claim 1 , wherein the reverse wheel component comprises a one-way bearing, a rotating shaft, and at least a pair of reverse wheels, the reverse wheels are sleeved on the rotating shaft, and the one-way bearing allows the reverse wheels to rotate about the rotating shaft in a unidirectional manner.

3. The banknote separating device according to claim 1 , wherein the first fixing frame, the reverse wheel set rotating shaft and the reverse wheel component are fixedly connected into a rigid body.

4. The banknote separating device according to claim 3 , wherein the second fixing frame is further provided with two fastening screw holes configured to mount with fastening screws for fixing the second fixing frame onto the reverse wheel set rotating shaft, which allows the second fixing frame, the reverse wheel set rotating shaft and the reverse wheel component to form a rigid body.

5. A radial gap adjusting method for a banknote separating device, comprising:
a first step: adjusting the first gap adjusting screw to allow the first fixing frame and an end, fixedly connected to the first fixing frame, of the reverse wheel component to move up and down along screw threads of the first gap adjusting screw, and further adjust a radial gap between the end, connected to the first fixing frame, of the reverse wheel component and the banknote separating wheel set;
a second step: adjusting the second gap adjusting screw to allow the second fixing frame and an end, fixedly connected to the second fixing frame, of the reverse wheel component to move up and down along screw threads of the second gap adjusting screw, and further adjust the radial gap between the end, connected to the second fixing frame, of the reverse wheel component and the banknote separating wheel set, and adjusting the radial gap to have a same width with the radial gap after the adjustment in the first step; and
a third step: screwing the fastening screws into the fastening screw holes of the second fixing frame to secure the second fixing frame onto the reverse wheel set rotating shaft.

6. The radial gap adjusting method for the banknote separating device according to claim 5 , wherein in the first step, the head portion of the first gap adjusting screw is in contact with the first gap adjustment stop block, and when the first gap adjusting screw is rotated clockwise, the first fixing frame and the end, fixedly connected to the first fixing frame, of the reverse wheel component move upwards along the screw threads of the first gap adjusting screw, which allows the radial gap between the reverse wheel set and the banknote separating wheel set to be increased; and when the first gap adjusting screw is rotated counterclockwise, the first fixing frame and the end, fixedly connected to the first fixing frame, of the reverse wheel component move downwards along the screw threads of the first gap adjusting screw, which allows the radial gap between the reverse wheel set and the banknote separating wheel set to be reduced.

7. The radial gap adjusting method for the banknote separating device according to claim 5 , wherein in the second step, the head portion of the second gap adjusting screw is in contact with the second gap adjustment stop structure, and when the second gap adjusting screw is rotated clockwise, the second fixing frame and the end, fixedly connected to the second fixing frame, of the reverse wheel component move upwards along the screw threads of the second gap adjusting screw, which allows the radial gap between the end, connected to the second fixing frame, of the reverse wheel component and the banknote separating wheel set to be increased; and when the second gap adjusting screw is rotated counterclockwise, the second fixing frame and the end, fixedly connected to the second fixing frame, of the reverse wheel component move downwards along the screw threads of the second gap adjusting screw, which allows the radial gap between the end, connected to the second fixing frame, of the reverse wheel component and the banknote separating wheel set to be reduced.
