Description

Technical Field

[0001] This utility model relates to the field of banknote bundling machine technology, and in particular to a punching device for a banknote bundling machine. Background Technology

[0002] In today's financial sector, banknote bundling is a crucial step, as its security and anti-counterfeiting features directly impact the stable operation of the financial system. As the core equipment for banknote bundling, the punching device of the banknote bundling machine plays a key role.

[0003] Existing banknote bundling machines typically use a wire-melting punch head to process the bundling tape. This wire-melting punch technology offers several significant advantages: during banknote bundling, the punch head uses high temperatures to melt the bundling tape, creating holes. On one hand, the resulting holes are clear and have neat edges, resulting in more secure holes compared to traditional mechanical punching methods. This greatly enhances the stability of the bundling, effectively preventing accidental loosening of the tape during transportation and storage, and ensuring the physical security of the banknote bundling. On the other hand, due to the combined effects of the punch head's temperature, processing time, and movement trajectory during the wire-melting punching process, the punched pattern on the bundling tape is unique. Furthermore, these holes, formed through melting, are irreversible and extremely difficult to counterfeit. These unique punched patterns naturally become a reliable anti-counterfeiting feature, significantly increasing the difficulty for criminals to forge the banknotes, building a solid defense for the safe operation of the financial system, and effectively resisting potential financial risks.

[0004] However, existing designs for fusion tape punch heads have a significant limitation: the punch head cannot be disassembled or replaced. In practical applications, with the continuous upgrading of financial security requirements and the diversified anti-counterfeiting requirements of different customer groups, there are more personalized demands regarding the style and complexity of punch patterns. However, because the punch head cannot be disassembled or replaced, banknote bundling machines can only punch one fixed style of hole pattern, failing to flexibly adapt to changes and severely restricting the applicability of banknote bundling machines in diverse scenarios.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a punching device for a banknote bundling machine, which is designed to facilitate the replacement of the melting head in order to meet the anti-counterfeiting requirements of the increasing financial security needs and the diversified customer groups.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A punching device for a banknote bundling machine includes a frame, a rotatable shaft and a transmission rod arranged horizontally on the frame, a strip punching head disposed in front of the shaft and transmission rod, and a drive mechanism for driving the transmission rod to rotate.

The punching head is inserted into the mounting hole of the base from top to top and locked by a locking structure. The top of the punching head integrally forms a heat-conducting sleeve for the insertion of the heating element.

[0009] As a further improvement to the above technical solution, the linkage structure includes a first swing arm and a second swing arm disposed on one side of the strip punching head.

[0010] As a further improvement to the above technical solution, the linkage structure also includes a third swing arm and a fourth swing arm disposed on the other side of the strip punching head. The third swing arm is located below the fourth swing arm. One end of the third swing arm is sleeved on the transmission rod, and the other end is hinged to the strip punching head. One end of the fourth swing arm is sleeved on the rotating shaft, and the other end is hinged to the strip punching head.

[0011] As a further improvement to the above technical solution, the first swing arm and the third swing arm are connected by a first sleeve, which can be laterally fitted onto the transmission rod; the second swing arm and the fourth swing arm are connected by a second sleeve, which can be laterally fitted onto the rotating shaft, and the first sleeve is threaded with a positioning screw for pressing the transmission rod to lock the position of the first sleeve.

Detailed Implementation

[0021] This utility model provides a punching device for a banknote bundling machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0022] Please see Figures 1 to 3This utility model provides a punching device for a banknote bundling machine, including a frame 1, a rotating shaft 2 and a transmission rod 3 rotatably and horizontally arranged on the frame 1, a strip punching head 7 arranged in front of the rotating shaft 2 and the transmission rod 3, and a drive mechanism 5 for driving the transmission rod 3 to rotate. The rotating shaft 2 and the transmission rod 3 are connected to the strip punching head 7 through a connecting rod structure 6, so that the strip punching head 7 can move up and down. The strip punching head 7 includes a base 71, a punching head 72, and a heating tube 73. The base 71 has a mounting hole 711 that runs from top to bottom. The punching head 72 is inserted into the mounting hole 711 of the base 71 from top to top and locked by a locking structure. The top of the punching head 72 is integrally formed with a heat-conducting sleeve 74 for the heating tube 73 to be inserted.

[0023] When the drive mechanism 5 is started, it drives the transmission rod 3 to rotate. Since the transmission rod 3 is connected to the rotating shaft 2 through the linkage structure 6, and the rotating shaft 2 is horizontally mounted on the frame 1 and can rotate, this linkage structure 6 plays the role of transmission and conversion of motion direction, converting the rotation of the transmission rod 3 into the up and down movement power of the strip punching head 7, thereby realizing the reciprocating motion of the strip punching head 7 in the vertical direction.

[0024] The heating element 73 generates heat when energized, and the heat is rapidly transferred to the welding head 72 through the heat-conducting sleeve 74 integrally formed on the top of the welding head 72. When it is necessary to punch a hole in the strapping, the welding head 72 moves downward under the action of the drive mechanism 5 and the connecting rod structure 6, so that the high-temperature welding head 72 contacts the strapping. The welding head 72 uses its high temperature to melt the strapping and punches a hole in the strapping according to the predetermined punching trajectory. After completing the punching action, the welding head 72 returns to its original position under the action of the drive mechanism 5, ready for the next punching operation.

[0025] When it is necessary to replace the fused hole head 72 to meet different drilling pattern requirements, first release the locking mechanism. Then, the old fused hole head 72 can be pulled out of the mounting hole 711 of the base 71. Then, insert the new fused hole head 72 into the mounting hole 711 from top to bottom, and lock it again through the locking mechanism. This completes the replacement of the fused hole head 72, making it convenient and quick to adapt to different drilling pattern requirements.

[0026] The punching device of the banknote bundling machine provided by this utility model adopts a replaceable melting head 72 design. By opening an installation hole 711 on the base 71, the melting head 72 can be easily inserted and removed and fixed by a locking structure. It can easily meet the requirements of financial security upgrades and the diversified anti-counterfeiting requirements of different customer groups. Users can replace the melting head 72 with different styles and complexities at any time according to actual needs, so that the banknote bundling machine can flexibly adapt to diverse scenarios, greatly expanding the applicability of the banknote bundling machine and effectively improving the equipment's ability to cope with complex and ever-changing market demands.

[0027] Furthermore, the fusion tape punch head 7 utilizes high-temperature melting of the binding tape to create holes, resulting in clear, neatly edged holes. Compared to traditional mechanical punching, the holes are more secure, greatly enhancing the stability of the binding and effectively preventing accidental loosening of the binding tape during transportation and storage, thus ensuring the physical security of banknote bindings. Simultaneously, the unique punching pattern formed during the punching process due to the combined effects of temperature, duration of action, and movement trajectory is irreversible and extremely difficult to counterfeit, serving as a reliable anti-counterfeiting feature. This significantly increases the difficulty for criminals to forge the product, effectively safeguarding the secure operation of the financial system.

[0028] Specifically, the linkage structure 6 includes a first swing arm 61 and a second swing arm 62 disposed on one side of the strip punching head 7. The first swing arm 61 is located below the second swing arm 62. One end of the first swing arm 61 is sleeved on the transmission rod 3, and the other end is hinged to the strip punching head 7. One end of the second swing arm 62 is sleeved on the rotating shaft 2, and the other end is hinged to the strip punching head 7. The first swing arm 61, with one end sleeved on the transmission rod 3, can accurately receive the rotational power transmitted by the transmission rod 3. Since its other end is hinged to the strip punching head 7, the power can be transmitted to the strip punching head 7 at a suitable angle and force, ensuring that the punching head moves up and down according to a predetermined trajectory. At the same time, the second swing arm 62, with one end sleeved on the rotating shaft 2, serves as a stable support and rotation component. Combined with the hinge of the second swing arm 62 to the strip punching head 7, it further assists in adjusting the movement posture of the punching head. The two work together to efficiently and accurately convert the rotational motion of the transmission rod 3 into the up-and-down linear motion of the strip punching head 7, ensuring the accuracy of the punching action and making the punched holes highly accurate, thus meeting the strict requirements of banknote bundling for consistent punching.

[0029] Furthermore, the linkage structure 6 also includes a third swing arm 63 and a fourth swing arm 64 disposed on the other side of the strip punching head 7. The third swing arm 63 is located below the fourth swing arm 64. One end of the third swing arm 63 is sleeved on the transmission rod 3, and the other end is hinged to the strip punching head 7. One end of the fourth swing arm 64 is sleeved on the rotating shaft 2, and the other end is hinged to the strip punching head 7. The addition of the third swing arm 63 and the fourth swing arm 64 on the other side of the strip punching head 7, together with the first swing arm 61 and the second swing arm 62 on the previous side, forms a symmetrical support and transmission structure on both sides. This symmetrical layout constrains and guides the strip punching head 7 from multiple directions, making it more stable during up and down movement, with almost no lateral deviation or swaying. When the drive mechanism 5 drives the transmission rod 3 to rotate, causing the punching head to move, the two swing arms work together to precisely control the trajectory of the punching head, ensuring that the position of each punch is accurate. This is crucial for banknote bundling operations that require high-precision punching, greatly improving the consistency and reliability of the bundling strap punching, and effectively reducing banknote bundling quality problems caused by punching errors.

[0030] To allow for adjustment of the punching position on the strapping tape, the lengths of the transmission rod 3 and the rotating shaft 2 are significantly longer than the width of the tape punching head 7, providing ample space for adjustment. The first swing arm 61 and the third swing arm 63 are connected via a first sleeve 65, which can be laterally fitted onto the transmission rod 3. The second swing arm 62 and the fourth swing arm 64 are connected via a second sleeve 66, which can be laterally fitted onto the rotating shaft 2. A positioning screw 67 is threaded onto the first sleeve 65 to lock the position of the first sleeve 65 by pressing the transmission rod 3. The operator can flexibly adjust the lateral position of the tape punching head 7 by moving the position of the first sleeve 65 on the transmission rod 3 and the second sleeve 66 on the rotating shaft 2, thereby changing the connection points between each swing arm of the linkage structure 6 and the transmission rod 3 and rotating shaft 2. Because the first sleeve 65 and the second sleeve 66 can be laterally mounted on the transmission rod 3 and the rotating shaft 2 respectively, the punching head can achieve precise displacement in the width direction of the strapping tape, meeting the needs of different specifications of strapping tape or diversified punching layouts. This ensures that each punch is accurately positioned in the required location, effectively improving the adaptability of the banknote bundling machine to different bundling tasks. When it is necessary to adjust the punching position, the operator only needs to loosen the positioning screw 67 on the first sleeve 65 to release the compression lock on the transmission rod 3, and then easily push the first sleeve 65 to slide on the transmission rod 3 to the target position. Then, tighten the positioning screw 67, and use the compression action of the threaded connection to lock the first sleeve 65 again. The operation process is simple and quick.

[0031] In this embodiment, the drive mechanism 5 includes a motor 51 fixed on the frame 1, a first gear 52 disposed on the output end of the motor 51, and a second gear 53 sleeved on the transmission rod 3. The first gear 52 and the second gear 53 mesh and transmit power. The gear transmission method has high mechanical efficiency, ensuring that power is efficiently transmitted from the motor 51 to the transmission rod 3, so that the transmission rod 3 obtains stable and strong rotational power, thereby ensuring the continuity of the up and down movement of the strip punching head 7. In frequent punching operations, there will be no problems such as punching jamming or unevenness due to insufficient power or fluctuations, meeting the needs of high-intensity and continuous operation in the financial field.

[0032] Furthermore, the cross-section of the transmission rod 3 is polygonal (e.g., square), and the end of the first swing arm 61 that engages with the transmission rod 3 forms a polygonal hole (e.g., square hole) that matches the shape of the transmission rod 3. This design ensures that there is no relative rotation between the first swing arm 61 and the transmission rod 3. When the drive mechanism 5 drives the transmission rod 3 to rotate, due to the polygonal structural characteristics, the transmission rod 3 can accurately transmit the rotational power to the first swing arm 61 in a predetermined direction, thereby driving the entire linkage structure 6 and causing the strip punching head 7 to move vertically along the designed trajectory.

[0033] Preferably, the frame 1 is equipped with a support plate 81, and the support plate 81 is equipped with a sensor 82 (such as an infrared reflection sensor). The sensor 82 is used to detect whether the punching head 7 has risen to the correct position. This arrangement can provide accurate position feedback for the entire punching operation. When the sensor 82 detects that the punching head has risen to the predetermined position, it sends a signal to the control system. Based on this, the control system accurately determines that a key node of the punching operation has been completed, and then arranges subsequent processes such as tape feeding and bundling in an orderly manner, ensuring that each operation step is closely connected and runs efficiently according to the preset program. This avoids process chaos caused by misjudging the position of the punching head, and effectively improves the working efficiency and automation level of the banknote bundling machine.

[0034] Preferably, the locking structure includes a fixing screw 75 threaded onto the base 71. The fixing screw 75 is used to press the heat-conducting sleeve 74 to fix the fusion head 72. When it is necessary to fix the fusion head 72, tightening the fixing screw 75 will cause the end of the screw to tightly press the heat-conducting sleeve 74, thereby firmly fixing the fusion head 72 in the mounting hole 711 of the base 71. This connection method is simple and direct, yet provides sufficient friction and fastening force to ensure that the fusion head 72 will not easily loosen or shift during the drilling process, even under various forces such as high temperature, vibration, and friction with the strapping. This ensures the stability and accuracy of the drilling operation and effectively prevents inconsistent hole quality caused by the shaking of the fusion head 72.
