Abstract
Description
Technical Field
[0001] This utility model relates to the field of banknote bundling machine technology, and in particular to a tape feeding device for a banknote bundling machine. Background Technology
[0002] Banknote bundling machines are widely used in banks, retail stores, and other settings that require handling large amounts of cash. Their main function is to neatly bundle banknotes into bundles for easy storage and transportation. During the operation of a banknote bundling machine, the strapping device plays a crucial role, ensuring that the strapping tape is smoothly and tightly delivered to the bundling position, guaranteeing that the banknotes are securely bound.
[0003] Traditional banknote bundling machine feeding devices typically consist of two main parts: a drive wheel and a pressure component. The drive wheel is rotated by a drive motor, propelling the bundling tape forward through friction; the pressure component provides the necessary clamping force to ensure the bundling tape adheres tightly to the banknotes. However, existing feeding devices have some shortcomings:
[0004] 1. In traditional designs, the clamping force between the pressure roller and the drive roller is usually fixed and cannot be adjusted according to different strapping requirements. This may result in the strapping tape being too loose or too tight, affecting the strapping effect and the reliability of the equipment.
[0005] 2. After long-term use, the design of fixed clamping force can easily lead to increased mechanical wear between the pressure roller and the drive roller, which in turn affects the service life and performance stability of the belt feeding device. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, this utility model provides a tape feeding device for a banknote bundling machine.
[0007] The technical solution adopted by this utility model to solve its technical problem is:
[0008] A tape feeding device for a banknote bundling machine includes: two feeding side plates arranged opposite to each other; a drive wheel rotatably disposed between the two feeding side plates, and the drive wheel being directly or indirectly connected to a drive motor; and a tape pressing component, the tape pressing component including a tape pressing frame located above the drive wheel, a tape pressing wheel rotatably disposed on the tape pressing frame, and an adjustment structure for adjusting the tightness between the tape pressing wheel and the drive wheel, wherein the outer arc surface of the tape pressing wheel is arranged opposite to the outer arc surface of the drive wheel.
[0009] The pressure frame is rotatably mounted on the feed side plate, and the pressure wheel is rotatable and eccentrically mounted on the pressure frame.
[0010] The adjustment structure includes a pressure plate connected to the feed side plate and an adjustment screw vertically downward mounted on the pressure plate, with the bottom end of the adjustment screw pressing against the pressure frame.
[0011] A rotatable guide pulley is provided upstream of the drive wheel.
[0012] The highest point where the guide wheel contacts the strapping is the first highest point, and the highest point where the drive wheel contacts the strapping is the second highest point. These first and second highest points are on the same horizontal plane.
[0013] The belt feeding device also includes a sensor and a detection disc fixedly connected to one end of the pressure roller. The detection disc has a plurality of protruding teeth arranged in an array around the rotation axis of the detection disc. When the detection disc rotates, the protruding teeth pass through the sensing area of the sensor.
[0014] A punching mechanism is provided on the downstream side of the drive wheel in the belt direction.
[0015] A guide groove is provided between the two feed side plates, located downstream of the drive wheel, and the guide groove is used to guide the strapping to the punching mechanism.
[0016] The punching mechanism includes a punching wheel and a driven wheel. The punching wheel has the same belt feeding speed as the driving wheel. The punching wheel includes a punching part disposed in the middle of the punching wheel and belt feeding parts disposed on both sides of the punching part. The punching part protrudes out of the outer side of the belt feeding part. The driven wheel has a recessed part that matches the punching part.
[0017] The beneficial effects of this invention are as follows: By introducing an adjustment structure to adjust the tension between the pressure roller and the drive roller, the feed length of the strapping tape can be controlled. This not only improves the binding accuracy but also ensures the quality of banknote binding, avoiding problems such as loose or overly tight binding due to improper clamping force. Furthermore, different types of strapping tape (such as different thicknesses or materials) have varying clamping force requirements. The adjustable clamping force design allows the device to adapt to various strapping tape types, enhancing its versatility and flexibility in different application scenarios and reducing the cost and inconvenience of replacing equipment for users. Moreover, after long-term use, if mechanical wear occurs on the pressure roller and drive roller, the tension between them can be adjusted through the adjustment structure to extend the device's service life and performance stability.

[0024] Reference Figures 1 to 3A feeding device for a banknote bundling machine includes: two feeding side plates 1, which are arranged opposite to each other. Specifically, a plurality of limiting posts 2 are provided between the two feeding side plates 1, and the feeding side plates 1 are respectively connected to the two ends of the limiting posts 2, with the feeding side plates 1 arranged opposite to each other on both sides of the limiting posts 2; a drive wheel 3, rotatably disposed between the two feeding side plates 1, and the drive wheel 3 is directly or indirectly connected to a drive motor 4. Specifically, the drive wheel 3 can be directly connected to the rotating shaft of the drive motor 4; or the drive wheel 3 can be indirectly connected to the drive motor 4 through other transmission components. In this embodiment, the drive motor 4 is connected to one of the feeding side plates 1. On the outer side of the feed side plate 1, the shaft of the drive motor 4 is fixedly connected to the drive wheel 3; preferably, a motor pad 5 is also provided between the drive motor 4 and the feed side plate 1. The drive motor 4 pad has a heat insulation function, which can prevent the heat of the drive motor 4 from being transferred to the strapping tape and affecting the strapping tape feeding effect; and a pressing component 6, which is movably configured. The pressing component 6 can be movably connected to the feed side plate 1, or the pressing component 6 can be movably connected to other parts of the banknote bundling machine. The movable connection can be a hinge or a sliding connection, as long as the pressing wheel 7 can abut against the drive wheel 3 and there is a certain amount of movement at the abutment point. In other words, the pressing wheel 7 can move between abutting against or separating from the drive wheel 3; specifically, the pressing component 6 includes a pressing frame 8 located above the drive wheel 3, a pressing wheel 7 rotatably mounted on the pressing frame 8, and an adjustment structure for adjusting the tightness between the pressing wheel 7 and the drive wheel 3. The pressure belt frame 8 can be hinged or slidably connected to the feed side plate 1. The outer arc surface of the pressure belt roller 7 is opposite to the outer arc surface of the drive roller 3. The outer arc surface refers to the surface that contacts the strapping strap, which passes between the pressure belt roller 7 and the drive roller 3. The adjustment structure 9 can adjust the tension between the pressure belt roller 7 and the drive roller 3 by increasing the weight of the pressure belt component 6 or the pressure of the pressure belt roller 7 on the drive roller 3; or it can adjust the movement allowance of the pressure belt roller 7 to adjust the tension between the pressure belt roller 7 and the drive roller 3. Moreover, in this embodiment, if mechanical wear occurs between the pressure belt roller 7 and the drive roller 3 after long-term use, the tension between the pressure belt roller 7 and the drive roller 3 can be adjusted by adjusting the structure 9 to extend the service life and performance stability of the device.
[0025] This embodiment introduces an adjustment structure 9 to adjust the tension between the pressure roller 7 and the drive roller 3, ensuring controllable feed length of the strapping tape. This not only improves the binding accuracy but also guarantees the quality of banknote binding, avoiding problems such as loose or overly tight binding due to improper clamping force. Furthermore, different types of strapping tape (such as those of different thicknesses or materials) have varying clamping force requirements. The adjustable clamping force design allows the equipment to adapt to various strapping tape types, enhancing its versatility and flexibility in different application scenarios, and reducing the cost and inconvenience for users when replacing equipment.
[0026] In some embodiments, the pressure frame 8 is rotatably mounted on the feed side plate 1, and the pressure roller 7 is rotatably and eccentrically mounted on the pressure frame 8. This design allows the pressure roller 7 on the drive roller 3 to be achieved using the weight of the pressure member 6 itself.
[0027] In some embodiments, the adjustment structure 9 includes a pressure plate 11 connected to the feed side plate and an adjustment screw 10 vertically downwardly disposed on the pressure plate. Specifically, the pressure roller 7 is disposed above the drive roller 3, the pressure plate 11 is disposed above the pressure roller 7, and the pressure plate 11 is fixedly or movably connected to the upper part of the feed side plate 1. In this embodiment, the pressure plate 11 is movably connected to the feed side plate 1, the position of the pressure plate 11 is adjustable, and it can be fixed in one position. When the pressure plate 11 is fixed, the movement space of the pressure roller 7 relative to the drive roller 3 can be adjusted by turning the adjustment screw 10.
[0028] In some embodiments, a rotatable guide pulley 13 is provided upstream of the drive pulley, and the strapping tape first passes through the guide pulley 13 and then enters between the drive pulley 3 and the pressure pulley 7.
[0029] In some embodiments, the first highest point of contact between the guide pulley 13 and the strapping tape, and the second highest point of contact between the drive pulley 3 and the strapping tape, are on the same horizontal plane. This design in this embodiment makes the strapping tape feeding smoother.
[0030] Reference Figure 2 In some embodiments, the device further includes a detection element. The belt feeding device also includes a sensor 14 and a detection disc 15 fixedly connected to one end of the pressure roller 7. The sensor 14 has a U-shaped opening, which is the sensing area of the sensor 14. The detection disc 15 has a plurality of protruding teeth 16 arranged in an array around the rotation axis of the detection disc 15. When the detection disc 15 rotates, the protruding teeth 16 pass through the sensing area of the sensor 14. The sensor 14 calculates the length of the feed belt by detecting the number of rotations of the detection disc 15.
[0031] Example 2
[0032] Reference Figure 4 The main difference between this embodiment and Embodiment 1 is the addition of a punching mechanism. This punching mechanism is located downstream of the drive wheel 3 in the belt-feeding direction. The belt-feeding direction refers to the direction in which the strapping tape enters the equipment. The punching mechanism is used to punch a hole in the center of the strapping tape. The shape of the hole is not limited; it can be round or other shapes. The punching mechanism can achieve punching through hot melting, stamping, or a combination of both.
[0033] In some embodiments, a guide groove 12 is provided between the two feed side plates, located downstream of the drive wheel. Under the projection of the axis of the drive wheel 3, the point of the drive wheel 3 closest to the pressure roller 7 overlaps with the guide groove 12. This guide groove guides the strapping to the punching mechanism. In this embodiment, the guide groove 12 is integrally designed with the feed side plate 1, and the guide groove 12 is a groove provided in the feed side plate 1, with the grooves of the two feed side plates 1 arranged opposite to each other.
[0034] In some embodiments, the punching mechanism includes a punching wheel 17 and a driven wheel 18, wherein the punching wheel 17 has the same belt feeding speed as the driving wheel 3. In this embodiment, the driving force of the punching wheel 17 comes from the driving wheel 3, and it receives the driving force of the driving wheel 3 through a synchronous belt 19. The punching wheel 17 includes a punching portion 20 disposed in the middle of the punching wheel 17, and belt feeding portions 21 disposed on both sides of the punching portion 20. The belt feeding speed of the belt feeding portions 21 is the same as that of the driving wheel 3. The punching portion 20 protrudes from the outer side of the belt feeding portion 21, and the driven wheel 18 has a recessed portion 22 that matches the punching portion 20. Specifically, the recessed portion 22 is an annular groove disposed in the middle of the driven wheel 18. When the strapping tape enters the punching wheel 17, the belt feeding portion 21 drives the strapping tape to continue entering the device, and the punching portion 20 cooperates with the recessed portion 22 to punch a hole in the middle of the width of the strapping tape by shearing. This design of the straps provides better breathability and also allows for unique markings.
[0035] The above embodiments do not limit the scope of protection of this invention. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this invention are still within the scope of this invention.
