2. When the paper sheet moves to the position of the opposite-emission optical fiber 62, the driving plate lifting assembly 22 stops working, the first driving wheel rotating assembly 51 works, under the driving of the first driving wheel rotating assembly 51, the upper paper separating wheel 41 and the paper twisting wheel 34 rotate, meanwhile, the driving arm rotating assembly 35 works to drive the swinging arm 32 to drive the rotating paper twisting wheel 34 to rotate downwards, so that the rotating paper twisting wheel 34 presses the paper sheet located at the paper twisting position, the paper sheet enters between the upper paper separating wheel 41 and the lower paper separating wheel 42 under the pushing of the friction force of the rotating paper twisting wheel 34, and when the paper sheet sensing optical fiber 91 senses the paper sheet, the driving arm rotating assembly 35 drives the swinging arm 32 to drive the paper twisting wheel 34 to rotate upwards, so that the paper twisting wheel 34 leaves the paper sheet.
3. The paper sheet entered between the upper paper separation wheel 41 and the lower paper separation wheel 42 is entered between the upper paper separation wheel 41 and the lower paper separation wheel 42 by the driving of the friction force of the rotating upper paper separation wheel 41, and because the size of the passage between the upper paper separation wheel 41 and the lower paper separation wheel 42 is limited and the friction force of the upper paper separation wheel 41 against the paper sheet is greater than the friction force of the lower paper separation wheel 42 against the paper sheet, the paper sheet between the upper paper separation wheel 41 and the lower paper separation wheel 42 is moved to the paper separation mechanism 40 by only one paper sheet.
4. When the paper output sensing optical fiber 92 senses a paper sheet, the first driving wheel rotating assembly 51 stops working, the upper paper dividing wheel 41 and the paper pickup wheel 34 stop rotating, and simultaneously the second driving wheel rotating assembly 74 works to drive the upper paper output wheel 72 to rotate, so that the paper sheet entering between the upper paper dividing wheel 41 and the lower paper dividing wheel 42 can pass through a channel between the upper paper output wheel 72 and the lower paper output wheel 73 under the pushing of the friction force of the upper paper dividing wheel 41 and move to the paper conveying mechanism 86. The upper and lower paper separation wheels 41 and 42 can further ensure that only one sheet is output because of the restriction of the size of the passage between the upper paper output wheel 72 and the lower paper output wheel 73 and the friction of the upper paper output wheel 72 against the sheet is greater than the friction of the lower paper output wheel 73 against the sheet.
5. The paper transport mechanism 86 transports the paper to the paper pick-up device, which operates to pick up the paper when the paper pick-up sensing fibers sense the paper, while the second drive wheel rotation assembly 74 stops driving the upper exit wheel 72 to rotate.
6. After the paper sheets are taken away, the paper sheet taking-away sensing optical fiber 93 cannot sense the paper sheets, the first driving wheel rotating assembly 51 works to drive the upper paper dividing wheel 41 and the paper twisting wheel 34 to rotate, and meanwhile, the driving arm rotating assembly 35 drives the swinging arm 32 to drive the rotating paper twisting wheel 34 to rotate downwards to press the paper sheets at the paper twisting position, so that the rotating paper twisting wheel 34 twists the paper sheets, and the paper sheets enter between the upper paper dividing wheel 41 and the lower paper dividing wheel 42.
7. The steps are repeated until the paper placed on the lift plate 21 of the paper carrying lift mechanism 20 is removed.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
