[0001] This utility model relates to the field of strapping machine technology, and in particular to a strap breaking device and a banknote bundling machine. Background Technology
[0002] In banks, financial institutions, and commercial establishments, banknote bundling machines are widely used to neatly bundle large quantities of banknotes together. Traditional banknote bundling machines typically include the following functional modules: strapping supply, tensioning, anti-reverse, heat sealing, and cutting. These modules work together to ensure that banknotes are securely and aesthetically bundled.
[0003] The existing banknote bundling machine's tape-breaking device has multiple cams, which drive the corresponding anti-reverse, hot-melt bonding, and shearing mechanisms to perform the melting operation. This multi-cam design makes the mechanical structure of the entire device very complex, increasing manufacturing costs and maintenance difficulties.
[0004] Since each mechanism is driven by a different cam, it is necessary to ensure that the working sequence of each mechanism is correct. If there is a problem with the working cycle, it may cause the backing, heat melting and shearing steps to be incomplete during the fuse operation, affecting the binding effect or even making binding impossible.

The upper end of the pressure block body is used to clamp the strapping between itself and the top plate.
[0011] As a further improvement to the above solution, a groove is provided in the middle of the top surface of the pressure block body, so that two protrusions are formed on the top of the pressure block body, and the two protrusions are arranged along the width direction of the strap.
[0012] As a further improvement to the above solution, the cutting mechanism includes a first cutter, a first spring, and a second cutter. The first cutter is disposed on the slider, which has a first channel arranged vertically. The first cutter is disposed in the first channel, and the first cutter and the first channel can slide up and down relative to each other. The first spring is arranged vertically, with its lower end connected to the slider and its upper end connected to the first cutter. The top of the first cutter is used to abut against the frame or top plate. The first cutter has a strapping hole. The second cutter is disposed on the slider, and the edge of the second cutter and the strapping hole is used to cut the strapping passing through the strapping hole.
[0013] As a further improvement to the above solution, the cutting mechanism also includes a second guide rod and a compression spring. The second guide rod is fixed on the slider and extends laterally. A guide hole is provided on the second cutter. The second guide rod and the guide hole are slidably engaged.

[0017] The beneficial effects of this invention are as follows: When bundling banknotes, the operator can place a stack of banknotes on the top surface of the top plate. The bundling strap is output from the external unwinding wheel, and the head of the strap is referred to as the upstream end. After passing through the cutting mechanism, the heat-sealing mechanism, and the pressure block in sequence, the upstream end of the strap circles the stack of banknotes and reaches the bottom of the top plate. At this time, the downstream end of the strap is located directly below the upstream end.

The heat-sealing mechanism heats the upstream end and the downstream end of the strap, so that the upstream end and the downstream end of the strap are heat-sealed and fixed together. Then, the cutting mechanism cuts off the connection between the strap output from the external unwinding wheel and the downstream end of the strap. In this invention, the pressure block, the cutting mechanism, and the heat-sealing mechanism are all driven upward by the driving mechanism, ensuring the accurate sequential action of each component.

[0026] Reference Figures 1-2 A strapping device includes a frame 1, a top plate 2, a guide rail, a slider 4, a drive mechanism 5, a pressure block, a cutting mechanism, and a heat-sealing mechanism 8. The top plate 2 is fixed on the frame 1. The guide rail is disposed on the frame 1 and extends vertically. The slider 4 is disposed on the guide rail and slides vertically relative to the guide rail. The drive mechanism 5 is disposed on the frame 1 and drives the slider 4 to move vertically. The pressure block is disposed on the slider 4 and is used to clamp the strapping between the pressure block and the top plate 2. The cutting mechanism is disposed on the slider 4 and is used to cut the strapping. The heat-sealing mechanism 8 is disposed on the slider 4 and is located between the pressure block and the cutting mechanism. The heat-sealing mechanism 8 is used to heat-seale the upstream end and the downstream end of the strapping, so that the upstream end and the downstream end of the strapping are fixedly connected.
[0027] As described above, during the banknote bundling process, the operator can place the entire stack of banknotes on the top surface of the top plate 2. The bundling strap is output from the external unwinding wheel, and the head of the strap is referred to as the upstream end. After passing through the cutting mechanism, the heat-sealing mechanism 8, and the pressure block in sequence, the upstream end of the strap circles the entire stack of banknotes and reaches below the top plate 2. At this time, the downstream end of the strap is located directly below the upstream end of the strap. The driving mechanism 5 drives the slider 4 to move upward along the guide rail, so that the pressure block presses the upstream end and the downstream end of the strap onto the frame 1 or the top plate 2. The heat-sealing mechanism 8 heats the upstream end and the downstream end of the strap, so that the upstream end and the downstream end of the strap are heat-sealed and fixed together. Then, the cutting mechanism cuts off the connection between the strap output from the external unwinding wheel and the downstream end of the strap. In this utility model, the pressure block, the cutting mechanism, and the heat-sealing mechanism 8 are all driven upward by the driving mechanism 5 to ensure accurate sequential action of each component.
[0028] In other words, after the strapping is output from the external unwinding wheel, the upstream end of the strapping passes sequentially through the cutting mechanism, the heat-sealing mechanism 8, and the pressure block. At this point, the upstream end of the strapping has passed below the top plate 2. Then, the upstream end of the strapping passes over the top of the top plate 2 where the banknotes are placed, and then returns to below the top plate 2, passing sequentially through the cutting mechanism, the heat-sealing mechanism 8, and the pressure block again. Driven by the drive mechanism 5, the pressure block presses the upstream and downstream ends of the strapping upwards onto the top plate 2.
[0029] In one embodiment, the guide rail includes two first guide rods 31, both of which are fixed to the frame 1. The slider 4 slides along the first guide rods 31. The first guide rods 31 guide the slider 4. In actual use, the first guide rods 31 extend vertically, allowing the slider 4 to slide up and down along them. The first guide rods 31 ensure that the slider 4 slides vertically. In some embodiments, after the drive mechanism 5 moves the slider 4 upward, the slider 4 can rely on gravity to move downward and reset.
[0030] In one embodiment, the drive mechanism 5 includes a motor 51, a cam 52, a return spring 53, and a swing arm 54. The middle part of the swing arm 54 is connected to the frame 1 by a rotating shaft, allowing relative rotation between the middle part of the swing arm 54 and the frame 1. The fixed part of the motor 51 is fixed to the frame 1, and the output end of the motor 51 drives the cam 52 to rotate. One end of the return spring 53 is connected to the slider 4, and the other end of the return spring 53 is connected to the frame 1 or the top plate 2. The top of one end of the swing arm 54 abuts against the bottom of the slider 4, and the top of the other end of the swing arm 54 abuts against the cam 52. In use, the motor 51 drives the cam 52 to rotate, and the cam 52 rotates to push one end of the swing arm 54 downwards, causing the middle part of the swing arm 54 to rotate around, thereby pushing the slider 4 upwards from the other end of the swing arm 54, thus driving the slider 4 to move upwards.
[0031] In some embodiments, the return spring 53 is fitted onto the first guide rod 31.
[0032] In one embodiment, the pressure block includes a pressure block body 61 and a buffer spring 62. A first vertically extending groove is provided on the slider 4, and the pressure block is disposed in the first groove. The pressure block and the first groove can slide vertically relative to each other. The buffer spring 62 is vertically arranged, with its upper end connected to the pressure block and its lower end connected to the slider 4. The upper end of the pressure block body 61 is used to clamp the strapping tape between itself and the top plate 2. The pressure block body 61 can slide vertically within the first groove. When the drive mechanism 5 moves the slider 4 upwards, the pressure block body 61 first presses down on the upstream and downstream ends of the strapping tape onto the top plate 2. Then, the drive mechanism 5 continues to move the slider 4 upwards, causing the heat-sealing mechanism 8 and the cutting mechanism to operate further. As the drive mechanism 5 continues to drive the slider 4 upward, since the pressure block body 61 has pressed the upstream and downstream ends of the strapping strap onto the top plate 2, the compression buffer spring 62 can be used to prevent damage to the top plate 2 or the pressure block while the drive mechanism 5 continues to drive the slider 4 upward, and at the same time ensure that the upstream and downstream ends of the strapping strap are pressed onto the top plate 2.
[0033] In one embodiment, a groove 611 is formed in the middle of the top surface of the pressure block body 61, so that two protrusions are formed on the top of the pressure block body 61, and the two protrusions are arranged along the width direction of the strap. By setting the groove 611, on the one hand, the material of the pressure block body 61 can be saved, and on the other hand, the two protrusions can provide very stable compression of the two sides of the strap width.
[0034] In one embodiment, the cutting mechanism includes a first cutter 71, a first spring 72, and a second cutter 73. The first cutter 71 is disposed on the slider 4, which has a first channel arranged vertically. The first cutter 71 is disposed in the first channel, and the first cutter 71 and the first channel can slide up and down relative to each other. The first spring 72 is arranged vertically, with its lower end connected to the slider 4 and its upper end connected to the first cutter 71. The top of the first cutter 71 is used to abut against the frame 1 or the top plate 2. The first cutter 71 has a strapping hole 710. The second cutter 73 is disposed on the slider 4, and the edges of the second cutter 73 and the strapping hole 710 are used to cut the strapping passing through the strapping hole 710.
[0035] In practical use, after the strapping is output from the external unwinding wheel, the upstream end of the strapping first passes through the strapping hole 710, then passes above the heat-sealing mechanism 8, and then above the pressure block. Next, the upstream end of the strapping passes above the top plate 2, then above the first cutter 71 and the second cutter 73, and then above the heat-sealing block 81 and the pressure block. The drive mechanism 5 drives the slider 4 to move upward, and the pressure block presses upward against the upstream end of the strapping and the strapping directly below it. At this time, the strapping directly below the upstream end of the strapping is called the downstream end of the strapping. Then, the drive mechanism 5 drives the slider 4 to continue moving upward. During this process, the buffer spring 62 is gradually compressed, and at the same time, the upper end of the first cutter 71 presses the strapping upward onto the top plate 2. Subsequently, the drive mechanism 5 continues to drive the slider 4 upward. During this process, the first spring 72 is compressed to prevent the first cutter 71 from being damaged. Then, driven by the drive mechanism 5, the slider 4 continues to move upward, carrying the second cutter 73 and the heat-sealing mechanism 8. This causes the heat-sealing mechanism 8 to heat-seal the strapping, while the second cutter 73 and the edge of the strapping hole 710 cut the strapping downstream of the unwinding wheel.
[0036] Optionally, there is no absolute order between the heat-sealing mechanism 8 heat-sealing the strapping and the second cutter 73 and the edge of the strapping hole 710 cutting the strapping. Preferably, the strapping is first heat-sealed by the heat-sealing mechanism 8, and then the strapping is cut by the second cutter 73 and the edge of the strapping hole 710.
[0037] In one embodiment, the cutting mechanism further includes a second guide rod 76 and a compression spring 75. The second guide rod 76 is fixed to the slider 4 and extends laterally. A guide hole is provided on the second cutter 73, and the second guide rod 76 and the guide hole are slidably engaged. One end of the compression spring 75 is connected to the second cutter 73, and the other end of the compression spring 75 is connected to the slider 4. The compression spring 75 is used to press the second cutter 73 against the first cutter 71. This structure is simple and easy to set up. With the setting of the second guide rod 76 and the compression spring 75, the second cutter 73 is tightly attached to the first cutter 71, ensuring that the edge of the second cutter 73 and the tape passage hole 710 can cut the strapping.
[0038] In one embodiment, the lower end of the first cutter 71 extends from the lower end of the first channel. The cutter mechanism also includes a tension spring 74, the lower end of which is connected to the lower end of the first cutter 71, and the upper end of which is connected to the slider 4. This structure is simple and easy to set up. The drive mechanism 5 drives the slider 4 to move upward, so that the first cutter 71 moves upward until it touches the top plate 2. If the drive mechanism 5 continues to drive the slider 4 upward, it will stretch the tension spring 74 and compress the first spring 72. When the drive mechanism 5 returns to its original position, the first cutter 71 can return to its original position through the tension spring 74 and the first spring 72. By simultaneously setting the first spring 72 and the tension spring 74, the position of the first cutter 71 after its return to its original position can be ensured to be relatively accurate.
[0039] In one embodiment, the heat-fusion mechanism 8 includes a heat-fusion block 81 and a second spring 82. The slider 4 has a second groove extending vertically along its length. The heat-fusion block 81 and the second groove are slidably connected vertically. The lower end of the second spring 82 is connected to the slider 4, and the upper end of the second spring 82 is connected to the heat-fusion block 81. The heat-fusion block 81 is disposed between the pressure block and the cutting mechanism. The heat-fusion block 81 is used to heat-fuse the upstream and downstream ends of the strapping, thus fixing the upstream and downstream ends of the strapping together. In practical use, the heat-fusion block 81 is existing technology; it uses electric heating to heat the strapping through contact, achieving heat fusion and connecting the upstream and downstream ends of the strapping together. With the second slide and the hot melt block 81, the hot melt block 81 can move up and down relative to the slider 4. With the second spring 82, it can be ensured that the hot melt block 81 presses the strapping, while avoiding the hot melt block 81 from damaging the top plate 2.

Since the tape-breaking device has already been described in detail above, those skilled in the art should be able to understand it by referring to the accompanying drawings; therefore, a further description of the tape-breaking device is not required here.
