After the cutting operation is completed, the pressure piece rises, and the bundled object can be taken out.

[0042] This embodiment has a high degree of automation. During the bundling operation, a pressure piece is provided to press the bundled object to ensure that the bundled object is pressed tightly to avoid loose bundling.

It should be noted that the lifting member 6 and the scissor-type articulated mechanism can be set on one side, or can be set symmetrically on both sides. In this embodiment, a bilaterally symmetrical setting is adopted.

[0044] In this embodiment, the sliding member 9 can drive the lifting member 6 to slide through the scissor-type hinge mechanism. Specifically, when the sliding member 9 slides away from the vertical lifting mechanism, it can drive the two connecting rods 8 to rotate in a direction close to each other, thereby lowering the lifting member 6; when the sliding member 9 slides in the direction of the vertical lifting mechanism, it drives the two connecting rods 8 to rotate in a direction away from each other, thereby raising the lifting member 6.

With this design, the lifting member 6 is stable and reliable, with a steady speed, can be stopped at any position in the stroke, and is not easily affected by external forces.

[0045] In some embodiments, the vertical lifting mechanism includes a table panel 5 fixedly arranged relative to the fixed plate 4, and the table panel 5 is slidably connected to the lifting member 6.

[0046] In some embodiments, the vertical lifting mechanism further includes a first photodetector 12 fixedly arranged relative to the fixed plate 4, and at least a portion of the lifting member 6 will pass through the detection area of ​​the first photodetector 12. In this embodiment, the first photodetector 12 is fixedly arranged on the table panel 5, and when the lifting member 6 is raised to the highest point, a portion of the lifting member 6 will pass through the detection area of ​​the first photodetector 12. At this time, the first photodetector 12 is triggered by the lifting member 6, and a signal is fed back to the control module (not shown in the figure), and then the control module controls the first driving member 2 to stop working, so as to prevent the lifting member 6 from sliding beyond the set stroke.

[0047] In some embodiments, the sliding member 9 includes a lower slide 13 slidably connected to the guide member, and an upper slide 14 slidably connected to the lower slide 13 directly or indirectly, and the two connection points on the other side of the scissor-type hinge mechanism are respectively hinged to the upper slide 14 and the lower slide 13, wherein the first driving member 2 can drive the upper slide 14 to slide in the vertical direction.

A screw rod set is also connected between the upper slide 14 and the lower slide 13, and the first driving member 2 can drive the screw rod set to rotate to drive the upper slide 14 to slide.

[0049] In some embodiments, the first driving member 2 is fixedly arranged relative to the lower slide 13, and the first driving member 2 can drive the screw assembly to rotate. Specifically, the first driving member 2 is a driving motor, which is fixedly connected to the lower slide 13, and the driving motor can drive the screw assembly to rotate to control the sliding of the upper slide 14. Further, the driving motor is arranged between the upper slide 14 and the lower slide 13. In this embodiment, the lower slide 13 has a shorter working stroke distance than the upper slide 14, so the first driving member 2 is fixedly arranged relative to the lower slide 13, and the circuit routing will be more convenient.

[0050] In some embodiments, the lower slide plate 13 is directly or indirectly fixedly connected with a motor fixing plate 16, which is arranged above the lower slide plate 13, and the motor fixing plate 16 is connected to the lower slide plate 13 through a hexagonal support.

The ball screw 21 is provided with a threaded section, which is rotatably connected to the screw rod sleeve 22.

This design ensures the stability of the lifting process, reduces vibration, and can make the lifting member 6 stop at any position in the stroke, thereby improving the safety and accuracy of the operation.

[0053] Reference Figures 4 to 6The pressurizing unit includes a support plate 1, a vertical lifting mechanism, a first driving member 2, a strapping guide rail 3 and a pressurizing member; the support plate 1 is arranged along the transverse direction; the vertical lifting mechanism includes a fixed plate 4, a table panel 5 fixedly arranged relative to the fixed plate 4, and a lifting member 6 slidable relative to the fixed plate 4, the fixed plate 4 is fixedly connected to the support plate 1, the lifting member 6 can slide vertically orthogonal to the transverse direction, and the lifting member 6 is slidably connected to the table panel 5; the first driving member 2 drives the lifting member 6 to slide; the strapping guide rail 3 is used for strapping straps, and the strapping guide rail 3 is fixedly connected to the top of the table panel 5; the pressurizing member is fixedly connected to the lifting member 6 and is arranged above the table panel 5; wherein the pressurizing member is provided with a pressurizing portion 7, and the pressurizing portion 7 is arranged at intervals on both sides of the strapping guide rail 3.

[0054] In some embodiments, both ends of the pressurizing part 7 are provided with inclined surfaces facing the table panel 5, and the inclined surfaces are arranged opposite to each other. It can also be said that the lowest points of the two ends of the pressurizing part 7 are lower in the vertical direction than the lowest point in the middle, or in other words, the cross-sectional area of ​​the two ends of the pressurizing part 7 is larger than the cross-sectional area of ​​the middle. With such a design in this embodiment, when the pressurizing part 7 presses the bundled object, the thickness of the edge of the bundled object is smaller than the thickness of the middle position. After the bundling is completed, the pressure at the edge is released, and the thickness of the edge of the bundled object is restored, so that the bundled object and the bundling belt fit better, thereby significantly improving the quality of bundling.

[0055] In some embodiments, an inner concave portion 27 is provided between the two inclined surfaces of the pressurizing portion 7, and the inner concave portion 27 is concave inwardly away from the table plate 5. The design of the inner concave portion 27 enables the pressurizing portion 7 to form a relatively low pressure area in the middle when in contact with the bundled object, while the inclined surfaces on both sides apply a higher pressure. This helps to ensure that the middle of the bundled object will not be deformed or damaged due to excessive compression, while ensuring that the edge parts are fully compressed.

[0056] In some embodiments, a safety plate 31 is connected to one side of the pressure member, and in the vertical direction, the safety plate 31 is protruding outside the pressure member. There is at least one safety plate 31, and the safety plate 31 is used to shield the area above and below the side of the pressure member. The safety plate 31 rises / falls together with the pressure member. During the pressing process, the safety plate 31 can shield the bundling area to prevent foreign objects from entering the bundling area to ensure safety.

[0057] Reference Figure 6In one embodiment, the pressure member includes a pressure plate 28, and a pressure part 7 connected to the pressure plate 28 and movable vertically, and a first elastic member 29 is arranged between the pressure part 7 and the pressure plate 28, and the first elastic member 29 enables the pressure part 7 to maintain a tendency to move toward the table panel 5. Specifically, the pressure plate 28 is fixedly connected to the lifting member 6, and the pressure part 7 is movably arranged relative to the pressure plate 28, and the pressure part 7 has a tendency to move toward the bundled object. When the pressure part 7 presses the bundled object, the buffer force provided by the first elastic member 29 can effectively prevent the bundled object from being damaged due to excessive pressure. The presence of the first elastic member 29 enables the pressure part 7 to retract appropriately when encountering resistance, thereby automatically adjusting the pressure applied to the bundled object to ensure that it is sufficiently tightened without causing damage. In addition, this mechanism can also adapt to bundles of different thicknesses and hardnesses, providing a more consistent and reliable compression effect.

[0058] In some embodiments, a proximity switch 30 is provided between the pressurizing part 7 and the pressurizing plate 28. The proximity switch 30 may be a mechanical switch or an inductive switch. When the pressurizing part 7 presses the bundled object, the pressurizing part 7 is forced to retract to a preset position by the reaction force, which triggers the proximity switch 30, thereby automatically stopping the pressurizing action. The presence of the proximity switch 30 provides additional safety protection, avoiding the risk of damage to the bundled object due to excessive compression, and is particularly suitable for handling sensitive or fragile items, such as banknotes, documents, etc.

[0059] Reference Figures 7 to 9 As shown, the alignment unit includes a support plate connected to the table panel 5, a mounting plate 101, a stopper 102 and a connecting mechanism 103. The mounting plate 101 is directly or indirectly fixedly connected to the upper part of the support plate. The mounting plate 101 can be indirectly fixedly connected to the upper part of the support plate through other parts, or the mounting plate 101 can be directly connected to the support plate; the stopper 102 is arranged on the upper part of the support plate, and is used to limit and position the position of the bundled object. Specifically, the stopper 102 has the function of limiting and positioning. When the bundled object is placed in the bundling position, it abuts against the stopper 102 to align and position the bundled object, so as to prevent the position of the bundled object from exceeding the bundling position.

[0060] The mounting plate 101 is connected to the limiting member 102 via a connecting mechanism 103, and the relative position of the limiting member 102 and the mounting plate 101 can be adjusted via the connecting mechanism 103; the connecting mechanism 103 can adopt a screw-type or scissor-type connection structure. The connecting mechanism 103 can support the limiting member 102, and when the state of the connecting mechanism 103 is changed, the position of the limiting member 102 is also changed. Among them, the connecting mechanism 103 is also provided with a locking mechanism, and the locking mechanism can lock the relative position of the limiting member 102 and the mounting plate 101. The locking mechanism locks / limits the position of the limiting member 102 by locking / limiting the movement of the connecting mechanism 103. Compared with the prior art, this embodiment does not require a motor drive, has a low manufacturing cost, a simpler structure, and is more convenient to maintain.

[0061] In some embodiments, the connection mechanism 103 includes a hinged first swing arm 104 and a second swing arm 105, one end of the first swing arm 104 and the second swing arm 105 is slidably hinged to the limiter 102, and the other end of the first swing arm 104 and the second swing arm 105 is slidably hinged to the mounting plate 101. Specifically, the connection mechanism 103 is a scissor-type structure, the middle part of the first swing arm 104 and the middle part of the second swing arm 105 are hinged, and the two ends of the first swing arm 104 and the second swing arm 105 are respectively hinged to the limiter 102 and the mounting plate 101, and the connection between the limiter 102 and the mounting plate 101 and the connection mechanism 103 is provided with a long hole 106, so that the first swing arm 104 and the second swing arm 105 can slide in the long hole 106. The use of the scissor-type connection mechanism 103 in this embodiment can make the limiter 102 more stable and not easy to loosen.

[0062] In some embodiments, the locking mechanism includes a limiting card slot 107 fixedly connected to the supporting plate, and a limiting card shaft 108 connected to the connecting mechanism 103. It can be understood that the limiting card shaft 108 can also be connected to the limiting member 102. The limiting card slot 107 is in the shape of an elongated strip, pointing along the direction of the mounting plate 101 to the limiting member 102. The limiting card slot 107 is provided with a plurality of card slots 109, and the limiting card shaft 108 can be stuck in the card slots 109. In this embodiment, there are two limiting card slots 107, which are respectively provided on both sides of the connecting mechanism 103. The limiting member 102 and the first swing arm 104 are hinged through the limiting card shaft 108. The two ends of the limiting card shaft 108 extend into the limiting card slot 107 respectively, and the limiting card shaft 108 can slide along the length direction of the long hole 106. The limiting clamping shaft 108 is placed in the clamping groove 109 to limit the position of the limiting member 102. Different clamping grooves 109 correspond to different positions of the limiting member 102. This embodiment has a simple structure, and the position of the limiting member 102 can be changed by simply placing the limiting clamping shaft 108 in different clamping grooves 109.

[0063] In some embodiments, the connection mechanism 103 and / or the limiting member 102 are provided with a second elastic member 110, and the second elastic member 110 keeps the limiting member 102 moving away from or close to the mounting plate 101. In this embodiment, the second elastic member 110 is a tension spring, one end of which is connected to the limiting member 102, and the other end of which is connected to the connection mechanism 103, so that the second swing arm 105 moves toward the first swing arm 104, so that the limiting member 102 keeps moving away from the mounting plate 101, and the limiting clamping shaft 108 has a thrust along the length direction of the limiting clamping slot 107, so that the limiting clamping shaft 108 and the limiting clamping slot 107 are not easily separated, and the limiting member 102 is supported more stably.

[0064] In some embodiments, the limiter 102 includes a limiter fixing plate 111, one side of the limiter fixing plate 111 is connected to the connection mechanism 103, and the other side of the limiter fixing plate 111 is fixedly connected to the limiter plate 112. The limiter fixing plate 111 can be made by bending a sheet metal, and the limiter plate 112 is used for aligning the bundled objects. Compared with the integral design of the limiter 102, the design of this embodiment makes the structure of the limiter 102 more reasonable and the cost lower.

[0065] In some embodiments, the limiter 102 is provided with a first travel switch 113, and a switch 114 of the first travel switch 113 is provided on a side facing the bundled object. The first travel switch 113 protrudes from the limiter 102, and when the bundled object is placed in the bundling station, the first travel switch 113 is triggered to confirm that the bundled object is in place.

[0066] In some embodiments, the limit member 102 is provided with an opening 115, and the switch 114 of the first travel switch 113 is exposed from the opening 115. Specifically, the opening 115 is provided on the side of the limit plate 112, the first travel switch 113 is fixed to the limit plate 112, and the switch 114 of the first travel switch 113 is exposed from the opening 115.

[0067] Reference Fig.10 In one embodiment, a locking switch 116 is provided at the hinge of the first swing arm 104 and the second swing arm 105, and the locking switch 116 can limit the rotation of the first swing arm 104 and the second swing arm 105. Specifically, the locking switch 116 includes a bolt with a head, and a nut connected to the bolt. The first swing arm 104 and the second swing arm 105 are hinged through the locking switch 116. When the bolt and the nut are locked, the connecting mechanism 103 cannot move to limit the position of the limit member 102; when the bolt and the nut are loosened, the connecting mechanism 103 can move to adjust the position of the limit member 102. With the design of this embodiment, the limit member 102 has more adjustable positions to meet the needs of bundled objects of different sizes.

[0068] Reference Figures 11 to 13The punching unit includes a fixing part, a punching part 202, a second driving part 201 and a transmission part 203; the fixing part is fixedly connected to the lifting part 6; the punching part 202 is used to punch holes in the strapping tape, and the punching part 202 is provided with a heating block 204. The strapping tape preferably uses a hot-melt strapping tape. The shape of the heating block 204 is not limited, and can be various shapes such as round, rectangular, and font. The heating block 204 can be heated and heated to a temperature higher than the melting point of the strapping tape; the second driving part 201 is fixedly connected to the fixing part and can provide a driving force for the punching part 202 to drive the punching part 202 to move. The second driving part 201 can be a cylinder, a driving motor, etc. Preferably, the second driving part 201 uses a DC reduction motor. The punching member 202 has a first position and a second position. When the punching member 202 is in the first position, the punching member 202 contacts the strapping tape and the strapping tape is melted at high temperature to punch holes in the strapping tape. Preferably, the punching position is selected in the middle of the width direction of the strapping tape; when the punching member 202 is in the second position, the punching member 202 does not contact the strapping tape. Specifically, in the second position, the punching member 202 cannot punch holes in the strapping tape, and the heat of the punching member 202 does not affect the strapping tape; this design enables the punching member 202 to perform the punching task at the correct position while protecting the strapping tape from additional damage.

[0069] Working principle: When the strapping tape of the banknote strapping machine is running, the punching member 202 reciprocates between the first position and the second position to punch holes in the strapping tape. Specifically, when the strapping tape reaches the specified position, the second driving member 201 drives the transmission member 203, and then the transmission member 203 drives the punching member 202 to move from the second position to the first position. At this time, the heating block 204 contacts the strapping tape and melts the strapping tape at high temperature to complete the punching action. Subsequently, the punching member 202 returns to the second position to prepare for the next punching cycle.

[0070] The punching element 202 of this embodiment is equipped with a heating block 204 that can be heated to a temperature higher than the melting point of the strapping tape, which can completely melt the strapping tape material to form clear and irreversible holes. This not only enhances the security of the strapping and prevents unauthorized operations, but also the unique punching pattern formed can be used as an anti-counterfeiting mark, increasing the difficulty of counterfeiting and protecting the security of the financial system. In addition, the holes punched in the strapping tape are relatively weak and easily damaged during the process of being torn and tampered, which increases the difficulty of tampering.

[0071] In some embodiments, the punching member 202 can reciprocate between the first position and the second position. In other words, the punching member 202 can reciprocate between the first position and the second position. The reciprocating motion of the punching member 202 can more accurately punch a hole in the middle of the strapping tape.

[0072] Reference Fig.11 In some embodiments, the direction in which the strapping belt (not shown) partially moves on the strapping belt guide rail 3 is a first direction (the first direction is Fig.11 The X direction of the mid-coordinate), the direction orthogonal to the first direction is the second direction (the second direction is Fig.11 The Z direction of the mid-coordinate), the direction orthogonal to the first direction and the second direction is the third direction (the third direction is Fig.11 In the Y direction of the mid-coordinate), when the punching member 202 moves from the first position to the second position, the position of the punching member 202 in the first direction remains unchanged. It can also be said that when the punching member 202 moves from the first position to the second position, the position of the punching member 202 in the second direction and the third direction changes. In the design of this embodiment, the punching member 202 does not have to be arranged directly above or below the strapping belt, so that the internal structure of the banknote strapping machine can be better designed, making the overall structure of the banknote strapping machine more compact and reasonable.

[0073] In some embodiments, the punching member 202 includes a connection seat 205, and a heating tube 206 sleeved inside the connection seat 205, the heating tube 206 abuts against the heating block 204. In this embodiment, a through cavity 207 is provided inside the connection seat 205, the heating tube 206 is fixedly connected to the cavity 207 of the connection seat 205, and the heating block 204 is protrudingly provided below the connection seat 205. The heating tube 206 can be electrically heated, the heating tube 206 abuts against the heating block 204, and the heat can be transferred to the heating block 204 to punch holes in the strapping tape. It can be understood that in this embodiment, the temperature of the heating block 204 can be changed to make the temperature of the heating block 204 lower than the melting point of the strapping tape, so that the punching unit can also be used to bond the strapping tape.

[0074] In some embodiments, in the second direction, the transmission member 203 includes a third swing arm 208, a fourth swing arm 209, a first rotating shaft 210, and a second rotating shaft 211 disposed below the first rotating shaft 210. At least one of the first rotating shaft 210 and the second rotating shaft 211 is rotatably supported on the fixing member, one end of the third swing arm 208 is connected to the first rotating shaft 210, and the other end of the third swing arm 208 is hinged to the punching member 202, one end of the fourth swing arm 209 is connected to the second rotating shaft 211, and the other end of the fourth swing arm 209 is hinged to the punching member 202, wherein at least one of the first rotating shaft 210 and the second rotating shaft 211 can receive the driving force of the second driving member 201, and transmit it to the punching member 202 through the third swing arm 208 and / or the fourth swing arm 209. In this embodiment, the first rotating shaft 210 and the second rotating shaft 211 are both rotatably supported on a fixed member, the third swing arm 208 is fixedly connected to the first rotating shaft 210, and the fourth swing arm 209 is fixedly connected to the second rotating shaft 211. The first rotating shaft 210 receives the driving force of the second driving member 201 to drive the punching member 202 to move, and the second rotating shaft 211 and the fourth swing arm 209 serve as followers to enable the punching member 202 to maintain a state in which the length direction of the punching member 202 is basically parallel to the second direction at different positions.

[0075] In some embodiments, a third elastic member 212 is disposed between the heating block 204 and the connection seat 205, and the third elastic member 212 enables the heating block 204 to maintain a movement tendency of protruding out of the connection seat 205. In this embodiment, the third elastic member 212 is disposed inside the connection seat 205, and when the pressure on the heating block 204 exceeds the elastic force of the third elastic member 212, the heating block 204 can move toward the connection seat 205. With such a design, the accuracy of the installation position of this embodiment can be slightly reduced.

[0076] In some embodiments, a limiting portion 213 is further included. When the punching member 202 moves away from the strapping band, the limiting portion 213 can limit the position of the punching member 202. The limiting portion 213 can be set in the fixing member to prevent the punching member 202 from exceeding the stroke, and can also be used for calibration and positioning of the punching member 202 at the second position.

[0077] In some embodiments, the limiting portion 213 is disposed on the third swing arm 208. When the punching member 202 moves away from the strapping belt, the third swing arm 208 may abut against the fourth swing arm 209 to limit the position of the punching member 202. Specifically, if the punching member 202 exceeds the set stroke, the third swing arm 208 and the fourth swing arm 209 will abut, or the third swing arm 208 and the fourth swing arm 209 will interfere with each other to limit the punching member 202 from continuing to move away from the strapping belt. In this embodiment, the limiting portion 213 is the edge of the connection between the third swing arm 208 and the first rotating shaft 210, that is, the end of the third swing arm 208 is larger than the middle.

[0078] In some embodiments, the second driving member 201 is a driving motor, the driving shaft of the driving motor is fixedly connected to the first cylindrical spur gear 214, the first rotating shaft 210 is also fixedly connected to the second cylindrical spur gear 215, and the first cylindrical spur gear 214 is meshed with the second cylindrical spur gear 215. In this embodiment, a DC reduction motor is selected, and the DC reduction motor can reciprocate to control the punching member 202. Such a design enables this embodiment to have higher precision and stability.

[0079] In some embodiments, the fixing member includes a left fixing plate 216 and a right fixing plate 217, the left fixing plate 216 and the right fixing plate 217 are arranged opposite to each other, the second driving member 201 is fixedly connected to the left fixing plate 216, the transmission member 203 is connected between the left fixing plate 216 and the right fixing plate 217, and the right fixing plate 217 is directly or indirectly connected to the second photodetector 218. The second photodetector 218 can detect the position of the punching member 202 to determine the punching speed of the punching member 202, and ensure that the punching member 202 operates at the set punching speed.

[0080] In some embodiments, a sensor fixing plate 219 is further included, the sensor fixing plate 219 is fixedly connected to the right fixing plate 217, and the sensor fixing plate 219 is provided with a first long hole 220, and the second photodetector 218 is adjustable in position and is provided in the first long hole 220. Such a design does not require high precision of the parts, and can improve the production efficiency of the parts.

[0081] Reference Figures 14 to 17 The fuse unit includes a top plate 301, a fuse mechanism 302 and a pushing member 303. The top plate 301 is fixedly connected to the top of the table plate 5 to prevent the fuse mechanism 302 from damaging the bundled object.

[0082] The fuse mechanism 302 is movably disposed below the top plate 301 relative to the top plate 301. Specifically, the fuse mechanism 302 can move toward the top plate 301. When the fuse mechanism 302 receives the force applied by the pushing member 303, it can move toward the top plate 301. When the pushing member 303 does not apply force to the fuse mechanism 302, the fuse mechanism 302 can be reset under its own gravity or the action of the elastic member.

[0083] The fuse mechanism 302 includes a hot melt component 304, a pressing knife 305, a cutting knife 306 and a stop plate 307. The hot melt component 304 is used to hot-melt the strapping tape. The hot melt component 304 can be heated to melt and bond the two ends of the strapping tape together. The pressing knife 305 is arranged on one side of the hot melt component 304 and is used to cooperate with the top plate 301 to clamp one end of the strapping tape. Specifically, when the strapping tape is fed to a specified position, the pressing knife 305 can move toward the top plate 301 to press the strapping tape at the specified position between the pressing knife 305 and the top plate 301. The cutting knife 306 is arranged close to the pressing knife 305 and can move relative to the pressing knife 305. The knife 305 moves. After the strapping tape is hot-melt bonded and the strapping tape needs to be cut, the cutter 306 and the pressing knife 305 move relative to each other to cut the other end of the strapping tape. The other end here refers to the position where the strapping tape needs to be cut after the strapping tape is unwound. The stop plate 307 is arranged on the other side of the hot-melt component 304 relative to the cutter 306. The stop plate 307 can move toward the top plate 301. When the strapping tape is unwound to the specified position, the stop plate 307 can cooperate with the top plate 301 to clamp the strapping tape.

[0084] The pushing member 303 is used to push the fuse mechanism 302 to move toward the top plate 301. Specifically, the hot melt 304, the pressing knife 305, the cutting knife 306 and the backstop plate 307 are all provided with driving force by the pushing member 303, so that the hot melt 304, the pressing knife 305, the cutting knife 306 and the backstop plate 307 move toward the top plate 301. The pushing member 303 has a force application point, which can push the hot melt 304, the pressing knife 305, the cutting knife 306 and the backstop plate 307 at the same time, wherein the pressing knife 305, the backstop plate 307 and the hot melt 304 can all be in contact with the strapping tape in sequence, and after the hot melt 304 is in contact with the strapping tape, the cutting knife 306 and the pressing knife 305 move relatively to shear the strapping tape. Specifically, the pushing member 303 pushes the fuse mechanism 302 to move the hot melt component 304, the pressing knife 305, the cutter 306 and the stop plate 307 toward the top plate 301. After the strapping tape is fed to the specified position, the pressing knife 305 first abuts against the top plate 301 to clamp the strapping tape in the specified position; then the equipment performs a strapping operation, and when the strapping tape is withdrawn to bundle the bundled object, the stop plate 307 moves to a position close to the top plate 301 to clamp the strapping tape; at this time, the hot melt component 304 is close to the top plate 301 to hot-melt the strapping tapes arranged up and down; at this time, the pushing member 303 still applies force to the fuse mechanism 302 to make the cutter 306 and the pressing knife 305 move relative to each other to shear the strapping tape. It should be noted that the hot melt 304, the pressing knife 305 and the stop plate 307 stop moving after moving to the designated position. After the entire bundling step is completed (the cutter 306 cuts the bundling belt), the hot melt 304, the pressing knife 305, the stop plate 307 and the cutter 306 return to the position to be worked (reset position) as the fuse mechanism 302 is reset. In order to stop the hot melt 304, the pressing knife 305 and the stop plate 307 from moving to the designated position, an elastic member can be provided to keep them in the corresponding position.

[0085] In this embodiment, the hot melt component 304, the pressing knife 305, the stop plate 307 and the cutting knife 306 are driven by the same pushing member 303, which makes the mechanical structure of the entire device simpler, reduces the manufacturing cost and maintenance difficulty, and ensures the precise synchronization between the various components, avoiding the situation that the stop, hot melt and shearing steps are not in place during the fusing operation, so as to ensure a good bundling effect.

[0086] In some embodiments, the pressing blade 305 is provided with a pressing portion 308 and a vacant portion 309, wherein the pressing portion 308 is provided above the vacant portion 309, and the strapping tape in the tape feeding process passes through the vacant portion 309. The vacant portion 309 can make the tape feeding method simpler.

[0087] In some embodiments, the cutter 306 is provided with a shearing portion 310, one side of the shearing portion 310 is in contact with the pressing knife 305, and the other side of the shearing portion 310 is gradually inclined from bottom to top toward the pressing knife 305. When it is necessary to shear the strapping tape, the height of the shearing portion 310 moves to a height exceeding the vacant portion 309, and the strapping tape in the vacant portion 309 is sheared. In this embodiment, the shearing portion 310 is sharper, and the shearing portion 310 is in contact with the pressing knife 305, making it easier to shear the strapping tape.

[0088] In some embodiments, the cutting portion 310 is serrated, and the sharpness of the cutting portion 310 is further increased to make the strapping tape easier to cut.

[0089] In some embodiments, when the fuse mechanism 302 does not receive the pushing force of the pushing member 303, the distances between the pressing blade 305, the stop plate 307, the hot melt component 304 and the top plate 301 increase in sequence. It can also be said that when the pressing blade 305, the stop plate 307 and the hot melt component 304 are in the waiting position, the height of the pressing blade 305 is higher than the stop plate 307, and the stop plate 307 is higher than the hot melt component 304. Such a design can ensure that the pressing blade 305, the stop plate 307 and the hot melt component 304 reach the working position in sequence.

The movable connection can be a hinged connection or a sliding connection, as long as the belt pressing wheel 407 can abut against the driving wheel 403 and there is a certain movable margin at the abutment.
