Description

TECHNICAL FIELD

[0001] The utility model relates to the field of banknote testing technology, specifically to a simple controllable banknote short side feeding mechanism. BACKGROUND

[0002] The role of the banknote feeding mechanism in the banknote testing process is crucial. It is responsible for feeding the banknotes into the banknote testing machine and ensuring that the banknotes can smoothly pass through each testing link of the banknote testing machine. A good banknote feeding mechanism can improve the working efficiency of the banknote testing machine, reduce the occurrence of banknote jamming, and thus improve the overall performance of the banknote testing machine.

[0003] Common banknote feeding mechanisms include vertical banknote feeding mechanisms and horizontal banknote feeding mechanisms. The vertical banknote feeding mechanism has the advantage of continuous banknote addition, but its structure is complex and not easy to miniaturize, and its cost is high. The horizontal banknote feeding mechanism has the advantage of simple structure, but banknotes cannot be added during the banknote counting process, and the single counting amount is small. However, both of these two methods are long-side banknote feeding, which is not conducive to the compact design of the entire machine, resulting in poor practicality of the banknote feeding mechanism. When the motor stops, the next level of transmission pulls the banknote, and the traditional mechanism does not rotate the banknote twisting wheel, causing the banknote to be under great stress and easily tilted, which cannot meet the working requirements of banknote testing. Therefore, a simple controllable banknote short side feeding mechanism is proposed. SUMMARY

[0005] In view of the deficiencies of the prior art, the utility model provides a simple controllable banknote short side feeding mechanism to solve the technical problem that the vertical banknote feeding mechanism and the horizontal banknote feeding mechanism are both long-side banknote feeding, which is not conducive to the compact design of the entire machine, resulting in poor practicality of the banknote feeding mechanism.

[0013] Preferably, the bottom part of the bill blocking plate is provided with a stainless steel pressing sheet on the upper side, resistance rubber sheets are arranged between the stainless steel pressing sheets on the bottom part of the bill blocking plate, and the stainless steel pressing sheet and the resistance rubber sheet are connected with the bill blocking plate through bolts.

[0014] Preferably, the assembly shaft is arranged on the upper side of the resistance sheet rotating shaft on the right inner part of the side plate, the adjusting screw is rotatably connected to the middle part of the inner part of the assembly shaft, the middle part of the bill blocking plate is arranged in an arc shape, the inclination angle of the bill blocking plate and the resistance rubber sheet can be adjusted by rotating the adjusting screw, the gap is changed, and the resistance is adjusted.

[0015] Preferably, the shaft rod is arranged on the left inner part of the side plate through a clamping spring, the knob is coaxially connected to the rear end of the shaft rod, the front end of the shaft rod is a threaded structure, and the side edge blocking plate is rotatably connected to the shaft rod.

[0016] Preferably, the shape of the side edge blocking plate is a U-shaped structure, the inner part of the side edge blocking plate is clamped on the outer part of the bill passing supporting plate, the rotation of the shaft rod is driven by rotating the knob, the side edge blocking plate moves, the bill is placed in the center, and the bill feeding is facilitated.

[0017] (Three) beneficial effects

[0018] Compared with the prior art, the simple controllable short-side bill feeding mechanism has the following beneficial effects:

[0019] 1. This simple and controllable short-side banknote feeding mechanism uses an added stepper motor to drive the first rotating shaft through the first synchronous belt pulley and its internal overrunning clutch. This allows the rotating banknote feeding wheel to feed in the bottom banknote, while the second to last banknote is blocked by the resistance rubber sheet. When the banknote enters the next stage of transmission, the stepper motor stops rotating, but the first rotating shaft where the banknote feeding wheel is located is connected by the overrunning clutch. Since the overrunning clutch has a one-way transmission characteristic, the banknote feeding wheel can continue to rotate until the banknote leaves. Because of the short-side banknote feeding method, the width of the whole machine is reduced, which is conducive to product miniaturization. Furthermore, banknotes can be fed continuously during feeding, and new banknotes can be added at any time, solving the problems of traditional horizontal banknote feeding mechanisms that cannot add banknotes in the middle, and vertical banknote feeding mechanisms that are complex in structure and difficult to maintain.

[0020] 2. This simple and controllable short-side banknote feeding mechanism, through the addition of a stepper motor, can precisely control the banknote feeding distance and banknote spacing. This allows the feeding mechanism to automatically control the feeding distance according to different banknote denominations, improving the practicality of the feeding mechanism. At the same time, due to the use of an overrunning clutch for one-way power transmission, the overrunning clutch and the first rotating shaft are essentially rigidly connected when the stepper motor rotates. This causes the banknote twisting wheel to rotate with the banknotes when they are pulled. At this time, the overrunning clutch disengages the first rotating shaft from the motor, reducing friction, preventing banknote tilting, and improving the quality of use of the feeding mechanism.
