Description

Technical Field

[0001] This invention belongs to the field of shredder technology, specifically relating to a financial bill shredder. Background Technology

[0002] A financial document shredder is an office device specifically designed to destroy paper financial documents. It can quickly shred sensitive documents such as bills, reports, and receipts into small pieces or granules. Through the collaboration of a high-strength blade assembly and a motor, it destroys the readability of the original information, preventing financial data from being maliciously recovered or leaked. Users only need to feed the document into the paper inlet, and the device will automatically complete the shredding process. It is simple to operate and highly efficient, and is suitable for places such as corporate finance departments and bank counters that need to handle confidential documents.

[0003] Unlike traditional paper shredders, financial bill shredders typically offer a higher level of security, cutting paper into irreparable fragments according to security standards. Using them can prevent the risk of discarded bills entering the external environment, avoiding the leakage of trade secrets or financial disputes caused by negligent disposal. Regularly destroying expired bills is also an important part of corporate compliance management, helping to establish a rigorous information protection mechanism and safeguard the economic security of customers and the company itself.

[0004] Financial invoices are typically bound together from multiple pages, with common binding methods including metal fasteners such as staples, paper clips, and pins. When these invoices are destroyed using a shredder, if the metal bindings enter the shredder along with the paper, they can severely damage the high-speed rotating blades, causing chipped teeth, accelerated wear, and even jamming the motor. Currently, most financial invoice shredders on the market do not have the function of actively separating metal bindings. Users need to manually remove the staples or paper clips one by one before shredding, a time-consuming and laborious process that is prone to missing some. A few devices attempt to use magnetic adsorption devices to attract some metal parts, but this is difficult to handle situations where staples are pressed tightly by paper or paper clips hold multiple layers of paper, resulting in unsatisfactory separation effects.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a financial bill shredder.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a financial bill shredder that can solve the problem that existing financial bill shredders cannot automatically separate metal binding materials such as staples and paper clips attached to the paper, which requires manual removal one by one and is easy to miss, resulting in blade damage and low shredding efficiency.

[0008] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: A financial bill shredder includes: a shredding and conveying pipe, a bill conveying mechanism, and a separating mechanism.

[0015] In one or more embodiments of the present invention, the adjusting assembly includes: an adjusting sliding block, an adjusting support frame, and a pair of adjusting springs.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0023] like Figures 1 to 5 As shown, a financial bill shredder according to one embodiment of the present invention includes: a shredding and conveying pipe 1, a bill conveying mechanism 2, and a separating mechanism 3. The bill conveying mechanism 2 includes a fixing component 21 disposed within the shredding and conveying pipe 1, a displacement component 22 disposed on the upper side of the shredding and conveying pipe 1, a synchronization component 23 disposed on one side of the shredding and conveying pipe 1, and an adjusting component 24 disposed on one side of the shredding and conveying pipe 1. The separating mechanism 3 includes a separating comb 31 disposed within the shredding and conveying pipe 1 and a collecting component 32 disposed outside the separating comb 31.

[0024] The shredding and conveying pipe 1, as the core channel structure of the entire device, provides a closed and clearly guided movement space for the conveying and separation of billing paper and metal binding materials. Designed as a cavity with a suitable length and cross-sectional shape according to the requirements of the billing conveying path, the pipe's inner wall surface is smoothed to reduce obstruction or jamming caused by friction during paper conveying. The shredding and conveying pipe 1 has reserved installation positions and movement spaces for cooperation with other components on its top, sides, and inside. For example, it has displacement grooves for the displacement support rod 222 to pass through, and bearing seat holes for the fixed installation shaft 211 to pass through. These structural features enable the shredding and conveying pipe 1 to not only provide physical support and protection, but more importantly, it organically integrates the billing conveying mechanism 2 and the separation mechanism 3, ensuring that the paper remains in a controlled and stable state throughout the entire process from entering the pipe to its final output to the shredding area. In addition, the crushing and conveying pipeline 1 is made of a material with certain strength and rigidity, which can resist the continuous force from elastic elements such as displacement spring 224 and adjusting spring 243, as well as the vibration generated when the synchronous motor 231 is running, thereby ensuring the reliability of the whole machine in long-term operation.

[0025] The bill delivery mechanism 2 is a key system for enabling the paper to move actively, keeping the paper flat, and maintaining the relative position of the paper and the metal binding. It consists of four subsystems working together: a fixing component 21, a displacement component 22, a synchronization component 23, and an adjustment component 24. The fixing component 21, as the lower part of the delivery channel, provides stable support and a friction drive surface; the displacement component 22, as the adjustable upper part, can adapt to bills of different thicknesses and apply appropriate clamping force; the synchronization component 23 ensures that the rotating parts in the fixing component 21 and the displacement component 22 rotate at the same linear speed, thereby avoiding paper wrinkles, tears, or delivery interruptions caused by speed differences; and the adjustment component 24 is responsible for maintaining the tension and meshing stability of the transmission components in the synchronization component 23, ensuring the continuity and accuracy of power transmission.

[0026] Through the close coordination of the four subsystems mentioned above, the bill conveying mechanism 2 can automatically and smoothly feed stacks or even single bills into the working area of ​​the separating mechanism 3 without manual intervention. During the conveying process, it continuously applies uniform pressure to the paper, making the protrusions of metal bindings (such as staples, paper clips, pins, etc.) more prominent relative to the paper, facilitating targeted picking by the subsequent separating comb 31. It is worth noting that the design of the bill conveying mechanism 2 fully considers the differences in the physical characteristics of different bills: for thinner, softer bills, the displacement component 22 automatically reduces the clamping gap and pressure using elastic elements to prevent paper damage; for thicker, firmly bound bills, the displacement component 22 can adaptively increase the gap and provide sufficient friction to ensure that the entire stack of paper moves as a whole without relative slippage. This adaptive adjustment capability greatly improves the equipment's compatibility in processing different types of financial bills.

[0027] like Figures 1 to 3 As shown, the fixing component 21 includes a fixing mounting shaft 211 and a fixing friction pad 212. The fixing mounting shaft 211 is disposed inside the crushing and conveying pipe 1. The fixing mounting shaft 211 guides the bill, and its rotation allows for displacement of the bill, ensuring that the bill can still be moved even when separated from the metal binding. The fixing friction pad 212 is disposed outside the fixing mounting shaft 211. The fixing friction pad 212 protects the bill and increases the friction between the fixing friction pad 212 and the bill. The fixing mounting shaft 211 passes through the crushing and conveying pipe 1, and a pair of fixing bearings 213 are disposed between the fixing mounting shaft 211 and the crushing and conveying pipe 1. The fixing bearings 213 reduce the friction between the fixing mounting shaft 211 and the crushing and conveying pipe 1, thereby increasing the service life of both the fixing mounting shaft 211 and the crushing and conveying pipe 1.

[0028] Specifically, the fixed mounting shaft 211 is a slender cylindrical rotating shaft with its axis perpendicular to the conveying direction of the bill and spanning the entire interior of the shredding conveying pipe 1 along its width. Both ends of the shaft extend out to the left and right sides of the shredding conveying pipe 1, with one end fixedly connected to one of the synchronizing secondary pulleys 233 in the synchronizing assembly 23, thereby obtaining rotational power. The portion of the fixed mounting shaft 211 located inside the shredding conveying pipe 1 has its outer surface tightly covered with a fixed friction pad 212. The fixed friction pad 212 is made of a material with a certain degree of elasticity, wear resistance, and a high coefficient of friction. Its surface can be designed with a fine texture or a rough texture to further enhance its gripping ability on the bill paper. When the bill enters from the inlet of the shredding conveying pipe 1, its lower surface first contacts the fixed friction pad 212. As the fixed friction pad 212 rotates continuously under the drive of the synchronizing assembly 23, it generates a forward frictional force on the bill along the conveying direction, propelling the paper forward. Meanwhile, the soft properties of the fixed friction pad 212 effectively cushion the risk of scratches to the paper from staple feet or paperclip edges on the bill surface, thus protecting the integrity of the paper. The fixed bearing 213 ensures that the fixed mounting shaft 211 maintains smooth, low-resistance rotation even under the downward pressure from the displacement assembly 22 and the dynamic load during bill delivery, preventing direct wear between the journal and the pipe wall, thereby significantly extending the overall maintenance cycle and service life of the machine.

[0029] like Figures 1 to 3 As shown, the displacement assembly 22 includes: a displacement frame 221, a displacement support rod 222, a pair of displacement balance rods 223, and a displacement spring 224. The displacement frame 221 is located on the upper side of the shredding and conveying pipe 1. The displacement frame 221 drives the displacement support rod 222, allowing it to engage with the fixed mounting shaft 211 to compress the bills. Even with multiple bills, they will not separate, facilitating the separation of metal-bound items. The displacement support rod 222 is located inside the shredding and conveying pipe 1. The pair of displacement balance rods 223 are located on the upper side of the shredding and conveying pipe 1. The displacement balance rods 223 support the displacement frame 221, reducing the likelihood of the displacement frame 221 tilting. The displacement spring 224 is sleeved on the outside of the displacement balance rods 223. The displacement spring 224 compresses the displacement frame 221, allowing the displacement support rod 222 to better compress the bills.

[0030] In detail, the displacement frame 221 is a roughly rectangular or U-shaped rigid support that spans above the crushing and conveying pipe 1 and can move up and down within a certain range in the vertical direction. The lower center or both sides of the displacement frame 221 are connected to the displacement support rod 222, allowing the displacement support rod 222 to rise and fall synchronously with the displacement frame 221. The displacement support rod 222 is arranged parallel to the fixed mounting shaft 211, and the vertical distance between them forms the gap through which the bills pass. When the displacement frame 221 is at its lowest position, the gap between the outer circumferential surface of the displacement support rod 222 and the fixed friction pad 212 on the fixed mounting shaft 211 is minimal, allowing sufficient clamping force to be applied to thinner single or a few bills. When the displacement frame 221 is pushed upwards by a thicker stack of bills, the displacement support rod 222 rises accordingly, automatically adapting to changes in bill thickness. A pair of displacement balance bars 223 are respectively installed on the left and right sides of the upper surface of the shredding and conveying pipe 1. They each pass through the corresponding guide holes on the displacement frame 221, providing precise vertical guidance for the displacement frame 221 and preventing it from tilting forward, backward, left, or right. This ensures that the axis of the displacement support bar 222 is always parallel to the axis of the fixed mounting shaft 211, thereby making the pressure on each point in the width direction of the bill uniform. A displacement spring 224 is sleeved on the outside of each displacement balance bar 223. Its upper or lower end abuts against the corresponding step surface of the displacement frame 221 and the shredding and conveying pipe 1, and is always in a compressed state, thus continuously applying a downward thrust to the displacement frame 221. This thrust is converted into pressure on the upper surface of the bill by the displacement support bar 222, ensuring sufficient static friction between the paper layers and between the paper and the fixed friction pad 212. This prevents the bill from slipping backward or the papers from separating when subjected to external force generated by the metal binding being pulled by the separating comb 31. Meanwhile, since the elastic force of the displacement spring 224 is linearly variable, when encountering particularly thick stacks of bills, the displacement frame 221 is lifted a greater distance, and the compression of the displacement spring 224 decreases, thereby appropriately reducing the applied pressure and avoiding excessive compression that could lead to paper tearing or excessive transport resistance. This adaptive pressure adjustment mechanism is one of the core advantages of the displacement assembly 22.

[0031] like Figures 1 to 4 As shown, a displacement groove matching the displacement support rod 222 is cut into the crushing and conveying pipeline 1, which facilitates the displacement of the displacement support rod 222. The displacement support rod 222 passes through the displacement frame 221. The displacement balance rod 223 passes through the displacement frame 221, and the displacement spring 224 is set between the displacement balance rod 223 and the displacement frame 221.

[0032] The design of the displacement groove not only provides a vertical movement channel for the displacement support rod 222, but its edge also serves as an auxiliary limit to prevent axial movement of the displacement support rod 222 during rotation. The specific connection method for the displacement support rod 222 through the displacement frame 221 can be a bearing connection, that is, the end of the displacement support rod 222 is mounted on the displacement frame 221 via a rolling bearing. This way, when the displacement support rod 222 is driven to rotate by the synchronization component 23, its rotational movement will not cause the displacement frame 221 to rotate together, and the lifting and lowering movement of the displacement frame 221 will not interfere with the rotation of the displacement support rod 222. The displacement balance rod 223, through the displacement frame 221, is typically fitted with a sliding bearing or a linear bearing to reduce friction and improve movement sensitivity. The displacement spring 224 is positioned between the displacement balance rod 223 and the displacement frame 221. Specifically, the lower end of the displacement spring 224 is supported on the boss of the crushing and conveying pipe 1, while the upper end abuts against the lower surface of the displacement frame 221, or vice versa, depending on the specific structural layout. Regardless of the arrangement, the displacement spring 224 is always in a compressed state, thus providing a continuous and stable downward pressure to the displacement frame 221. In addition, to further optimize the uniformity of pressure distribution, multiple elastic pads can be added between the displacement frame 221 and the displacement support rod 222, or a multi-point spring support structure can be used, but this does not change the basic structure and function of the displacement assembly 22.

[0033] like Figures 1 to 4 As shown, the synchronization component 23 includes: a synchronous motor 231, a synchronous main pulley 232, a pair of synchronous secondary pulleys 233, and a synchronous conveyor belt 234. The synchronous motor 231 is located on one side of the crushing and conveying pipe 1. The synchronous motor 231 drives the rotation of the synchronous main pulley 232, providing the necessary power for its rotation. The synchronous main pulley 232 is located on one side of the synchronous motor 231. The synchronous main pulley 232 drives the rotation of the pair of synchronous secondary pulleys 233, which in turn drives the rotation of the fixed mounting shaft 211 and the displacement support rod 222, providing the necessary power for conveying the bill. The pair of synchronous secondary pulleys 233 are respectively located at one end of the fixed mounting shaft 211 and the displacement support rod 222. The synchronous conveyor belt 234 is located between the pair of synchronous secondary pulleys 233 and the synchronous main pulley 232, and the synchronous conveyor belt 234 serves a synchronizing function.

[0034] More specifically, the synchronous motor 231 is selected from motor types capable of providing stable speed and sufficient torque, and its output shaft is directly and fixedly connected to the hub of the synchronous main pulley 232. The outer circumference of the synchronous main pulley 232 is designed with toothed grooves or smooth surfaces that match the inner circumference of the synchronous conveyor belt 234 to transmit power without slippage. A pair of synchronous secondary pulleys 233 are respectively mounted on the same side end of the fixed mounting shaft 211 and the displacement support rod 222. Their diameters are typically the same as the diameter of the synchronous main pulley 232 or designed in a specific ratio to ensure that the rotational speeds of the fixed mounting shaft 211 and the displacement support rod 222 are equal or meet the speed ratio required for conveying. In this invention, to achieve the best bill conveying effect, the pair of synchronous secondary pulleys 233 are typically designed with the same diameter as the synchronous main pulley 232, thereby ensuring that the angular velocities of the fixed mounting shaft 211 and the displacement support rod 222 are the same, and consequently, the linear velocities of their outer circumferences are also consistent. Since the fixed mounting shaft 211 and the displacement support rod 222 are located below and above the bill respectively, and they rotate in opposite directions at the same linear speed (one clockwise and one counterclockwise), a pure forward conveying force is generated on the bill sandwiched in the middle, without any additional shearing or rubbing effect due to speed difference, thus protecting the paper from damage. The synchronous conveyor belt 234 can be a toothed synchronous belt or a flat belt. Considering transmission accuracy and load capacity, a synchronous belt with internal teeth is preferred, which meshes with the toothed grooves on the synchronous main pulley 232 and the synchronous secondary pulley 233 to achieve precise synchronous transmission without slippage. The synchronous assembly 23 is located on the side of the shredding and conveying pipe 1, which facilitates the maintenance and replacement of the synchronous conveyor belt 234 without interfering with the flow path of the paper inside the shredding and conveying pipe 1.

[0035] like Figures 1 to 5 As shown, the adjusting assembly 24 includes: an adjusting sliding block 241, an adjusting support frame 242, and a pair of adjusting springs 243. The adjusting sliding block 241 is disposed on one side of the crushing and conveying pipe 1 and is fixedly connected to the synchronous motor 231. The adjusting sliding block 241 supports the synchronous motor 231, improving its stability. The adjusting support frame 242 is disposed on one side of the crushing and conveying pipe 1 and extends through the adjusting sliding block 241. The adjusting support frame 242 supports the adjusting sliding block 241, facilitating its sliding and improving the stability of the adjusting support frame 242. The pair of adjusting springs 243 are sleeved on the adjusting support frame 242. The adjusting springs 243 compress the adjusting sliding block 241, allowing the synchronous motor 231 to move away from or closer to the pair of synchronous secondary pulleys 233, thus making the transmission between the synchronous primary pulley 232 and the pair of synchronous secondary pulleys 233 more stable.

[0036] In detail, the adjusting sliding block 241 is a movable base on which the synchronous motor 231 is mounted by bolts or other fixing methods. The adjusting sliding block 241 itself is sleeved on the guide rod or guide rail of the adjusting support frame 242, and can slide horizontally in a direction away from or towards the crushing and conveying pipe 1. The adjusting support frame 242 is fixedly installed on the side wall of the crushing and conveying pipe 1. It is usually composed of two parallel cylindrical guide rails or a rectangular beam with a groove, which passes through the guide hole on the adjusting sliding block 241, providing a precise linear motion trajectory for the adjusting sliding block 241. A pair of adjusting springs 243 are respectively sleeved on the two guide rails of the adjusting support frame 242. One end of each spring abuts against the adjusting sliding block 241, and the other end abuts against a baffle or retaining ring fixed to the end of the adjusting support frame 242. The spring force of the adjusting springs 243 is designed to push the adjusting sliding block 241 towards the crushing and conveying pipe 1, thereby bringing the synchronous motor 231 and its synchronous main pulley 232 mounted on the adjusting sliding block 241 closer to the synchronous secondary pulley 233 at the end of the fixed mounting shaft 211 and the displacement support rod 222. This ensures that the synchronous conveyor belt 234 is always under a certain tension during operation, preventing problems such as tooth skipping, slippage, or transmission failure caused by the synchronous conveyor belt 234 loosening due to long-term use. Simultaneously, when it is necessary to replace the synchronous conveyor belt 234 or perform maintenance, the spring force of the adjusting springs 243 can be manually overcome, and the adjusting sliding block 241 can be pulled outwards, thus easily removing the synchronous conveyor belt 234. The spring force of the adjusting springs 243 is reasonably selected, neither too large to cause additional load on the synchronous bearings nor too small to cause insufficient tension. Furthermore, the adjusting assembly 24 also indirectly acts as a buffer: when the synchronous motor 231 generates impact torque during startup or shutdown, the adjusting springs 243 can absorb some of the vibration, protecting other components of the transmission system. The design of the entire adjustment assembly 24 fully reflects the consideration for the long-term stable operation of the transmission system and is one of the key links to ensure the continuous and reliable operation of the bill delivery mechanism 2.

[0037] like Figures 1 to 4 As shown, the collection assembly 32 includes a collection bin 321, a collection motor 322, and a collection support shaft 323. The collection bin 321 is located outside the separating comb 31 and is fixedly connected to the shredding and conveying pipe 1. The collection bin 321 collects metal binding materials, reducing the likelihood of residual metal binding materials in the shredding and conveying pipe 1. The collection motor 322 is located on one side of the collection bin 321, and its location allows the collection assembly 32 to drive the rotation of the separating comb 31. The collection support shaft 323 is located on the side of the collection motor 322 closest to the collection bin 321.

[0038] To elaborate further, the collection chamber 321 is a container independent of but fixedly connected to the shredding and conveying pipe 1. Its internal space is connected to the interior of the shredding and conveying pipe 1 through the combing grooves of the separating comb 31. When the separating comb 31 rotates and hooks the metal bindings off the paper, these metal bindings are thrown or fall into the collection chamber 321 under the centrifugal force and the continuous agitation of the separating comb 31. The bottom or side of the collection chamber 321 can be designed as an openable flip-top or drawer structure, facilitating the operator to periodically clean the collected staples, paper clips, and other debris. The inner wall of the collection chamber 321 can be coated with an antistatic coating or have magnetic adsorption areas to prevent small metal fragments from flying or falling back into the shredding and conveying pipe 1. The collection motor 322 is installed outside the collection chamber 321, and its output shaft is connected to one end of the collection support shaft 323 via a coupling or directly. The collecting support shaft 323 passes through the side wall of the collecting chamber 321 and enters the interior of the shredding conveying pipe 1. The separating comb 31 is fixedly installed on the section of the collecting support shaft 323 located inside the shredding conveying pipe 1. Sealed bearings are provided between the collecting support shaft 323 and the collecting chamber 321, as well as the side wall of the shredding conveying pipe 1, to prevent dust or paper scraps from entering the bearings and to prevent metal binding materials from leaking out of the shaft hole gaps. The collecting motor 322 is typically a type of motor that can provide a large starting torque because when the separating comb 31 encounters a staple tightly clamped by paper, it needs to overcome considerable resistance to successfully hook it out. By appropriately selecting the rotation speed of the collecting motor 322 and the rotation direction of the separating comb 31, it can be ensured that the pulling action of the separating comb 31 forms a certain cross or opposite angle with the forward direction of the bill, thereby efficiently picking out the metal binding materials, rather than simply pushing them along the paper surface.

[0039] like Figures 1 to 5 As shown, the collection bin 321 is fixedly connected to the crushing and conveying pipe 1. The collection support shaft 323 passes through the collection bin 321 and the separation comb 31. The separation comb 31 has multiple combing grooves, which can separate the metal bindings from the bills.

[0040] The overall shape of the separating comb 31 can be a cylindrical or disc-shaped structure, with multiple axially or circumferentially arranged combing grooves evenly carved on its circumferential surface. The width and depth of these combing grooves are designed to accommodate the staple feet or curved portions of paper clips without causing the entire sheet of paper to sink into them. When the bill, which has been squeezed and conveyed by the fixing component 21 and the displacement component 22, reaches the position of the separating comb 31, the upper or lower surface of the bill (depending on the installation position of the separating comb 31) will be pressed against the outer edge of the separating comb 31. As the separating comb 31 rotates under the drive of the collecting motor 322, the combing grooves on it will repeatedly glide across the surface of the bill. For flat paper surfaces, the combing grooves will only lightly glide over them without damaging the paper; however, for protruding metal bindings, the edges of the combing grooves will catch them and generate an outward pulling force as the separating comb 31 rotates. As the bill itself continues to be conveyed forward by the fixing component 21 and the displacement component 22, while the metal binding is pulled backward or sideways by the separating comb 31, relative movement occurs between the two, ultimately causing the metal binding to be completely pulled out of the paper. The pulled-out metal binding will temporarily adhere to the combing grooves of the separating comb 31 or get stuck between the teeth, and as the separating comb 31 continues to rotate, it falls into the collection bin 321 under the combined action of centrifugal force and gravity. To further improve the separation efficiency, multiple separating combs 31 can be set in the shredding and conveying pipe 1, or the rotation direction of the separating comb 31 can be designed to be opposite to the bill conveying direction to generate stronger relative movement. At the same time, the material of the separating comb 31 should be selected as a metal or engineering plastic with high hardness and good toughness to resist the wear of the metal binding on its edges. The arrangement density of the combing grooves, the groove angle, and other parameters can be optimized according to the size range of common metal bindings, but the present invention does not limit specific values, but achieves a universal separation effect through the adaptability of the structure itself. Through the cooperation of the separation comb 31 and the collection component 32, the present invention achieves automatic, continuous and efficient separation and collection of metal binding materials, and completely solves the problem of relying on manual dismantling and easy omission in the prior art.
