Description

Technical Field

[0001] The present invention relates to the technical field of waste ticket shredding, and in particular to a shredding treatment device for accounting financial waste tickets with privacy protection. Background Technique

[0002] Accounting financial waste tickets usually refer to the tickets that are invalidated due to various reasons and cannot be used as valid vouchers during the accounting and financial management processes. In order to avoid the problem of privacy leakage caused by accounting financial waste tickets, it is necessary to cut or shred the waste tickets for treatment, so as to avoid the situation of privacy leakage.

[0003] However, when the existing shredding treatment device for accounting financial waste tickets with privacy protection is in use, there are still certain problems:

[0004] Existing is a kind of accounting voucher processing device for financial accounting, such as the Chinese patent application number CN202122064472.1, which includes a housing, a mounting frame and a collection box; Housing: An installation groove is provided on the right side inside. The mounting frame passes through the through groove on the left side of the housing and is clamped with the installation groove. Motors are provided on both the front and rear sides of the left side of the mounting frame. The output shaft of the motor is connected to the left end of the shredding blade. The shredding blade is rotatably connected inside the mounting frame. The collection box is arranged at the bottom inside the housing. Insert the mounting frame into the installation groove through the through groove on the left side of the housing;

[0005] However, when the existing accounting financial waste tickets are shredded, only one-way cutting treatment can be achieved. The waste tickets are in strip shape with a large overall volume and are easy to splice again, which is likely to cause privacy leakage;

[0006] In view of the above problems, an innovative design is carried out on the basis of the original shredding treatment device for accounting financial waste tickets with privacy protection. Summary of the Invention

[0007] The purpose of the present invention is to provide a shredding treatment device for accounting financial waste tickets with privacy protection, so as to solve the problem that the shredded waste tickets of the existing waste ticket shredding device have a large volume, are easy to splice again in strip shape, and are likely to cause privacy leakage as mentioned in the above background technique.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A shredding treatment device for accounting financial waste tickets with privacy protection, including a housing and a collection box arranged at the bottom for collecting waste paper debris. A "V"-shaped feed inlet is opened at the upper end of the housing:

[0009] A rotating shaft is connected to the upper end of the housing, a cutting blade is connected to the outside of the rotating shaft, the rear end of the rotating shaft is connected to a first motor, and a synchronous gear is fixed to the front end of the rotating shaft;

[0010] A flow guide plate is fixed in the middle of the housing. There is a first cutting knife at the lower end of the flow guide plate. Second motors are fixed on both sides of the flow guide plate. A transmission component is connected between the second motors and the first cutting knife to enable the first cutting knife to reciprocally cut the paper.

[0011] A second cutting knife is arranged at the lower end of the first cutting knife. A transmission connecting rod is connected between the second cutting knife and the first cutting knife. The transmission connecting rod keeps the two cutting structures moving synchronously. A support frame is fixed outside the second cutting knife. An angle adjustment component is connected to the lower end of the support frame, which can realize the horizontal angle adjustment of the second cutting knife and achieve the irregular shape of the shredded paper scraps.

[0012] Preferably, the rotating shaft is rotatably connected to the housing, and the front end of the rotating shaft extends to the outside of the housing and is connected to a synchronous gear. Two groups of the rotating shaft and the synchronous gear are symmetrically arranged, and the two synchronous gears are meshed with each other.

[0013] Preferably, the cutting blades are equidistantly and arrayedly distributed outside the two rotating shafts, and the left and right cutting blades are arranged in a staggered manner.

[0014] Adopting the above technical solution, the first motor can provide rotational power for one group of rotating shafts, and the cooperation of the two synchronous gears can realize the reverse rotation of the two groups of rotating shafts and cutting blades, thereby realizing the strip cutting of accounting financial documents.

[0015] Preferably, an impeller is arranged between two adjacent cutting blades, and the impeller is fixed to the rotating shaft.

[0016] Adopting the above technical solution, through the design of the impeller, when the rotating shaft and the cutting blades rotate and cut, the impeller can drive the air to flow downward, and keep the strip-shaped waste tickets in a hanging state, ensuring stable cutting and also avoiding the blockage of the strip-shaped waste tickets.

[0017] Preferably, the upper end shape of the flow guide plate is adapted to the cutting blade, and a "V"-shaped flow guide groove is opened in the middle of the flow guide plate.

[0018] Adopting the above technical solution, the "V"-shaped flow guide groove can improve the smoothness of the downward movement of the strip-shaped waste tickets.

[0019] Preferably, two groups of the first cutting knives are arranged, and the inner sides of the two groups of first cutting knives are in contact with each other. The two ends of the first cutting knife are slidably connected to the inner wall of the housing.

[0020] Adopting the above technical solution, the two groups of first cutting knives can cut and truncate the strip-shaped waste tickets when moving relative to each other, thereby cutting the long strip-shaped waste tickets into small pieces.

[0021] Preferably, a transmission plate is fixed in the middle of the outer side of the first cutting knife. The transmission plate is designed in a "T" shape, and a transmission groove is formed on the outer side of the transmission plate. The lower shaft of the second motor extends outside the diversion plate, and a first turntable is fixed to the lower shaft end of the second motor. A first transmission shaft is fixed eccentrically at the lower end of the first turntable. The lower end of the first transmission shaft extends into the transmission groove, and the first transmission shaft slides inside the transmission groove.

[0022] With the above technical solution, the rotation of the second motor can drive the first turntable and the first transmission shaft to rotate synchronously, and drive the first transmission shaft to move circumferentially around the motor shaft. When the first transmission shaft moves inside the transmission groove, it can drive the two groups of transmission plates and the first cutting knife to reciprocate in opposite directions, so as to realize the cutting and truncation of long strip-shaped waste tickets.

[0023] Preferably, the transmission connecting rods are symmetrically arranged on the front and rear sides of the first cutting knife. The upper ends of the transmission connecting rods are rotatably connected to the first cutting knife. Limiting sliding grooves are formed on the outer sides of the front and rear ends of the second cutting knife. The lower ends of the transmission connecting rods are rotatably connected with roller shafts, and the roller shafts are slidably matched with the limiting sliding grooves;

[0024] The inner side end of the support frame is rotatably connected with a second turntable, and a second transmission shaft is connected eccentrically inside the second turntable. The second transmission shaft is fixed to the second cutting knife. The second turntable and the second transmission shaft are mirror-symmetrically distributed at both ends of the second cutting knife.

[0025] With the above technical solution, through the design of the transmission connecting rods, the first cutting knife and the second cutting knife can be connected, keeping the first cutting knife and the second cutting knife moving synchronously in parallel, realizing the synchronous cutting of strip-shaped waste tickets. The cooperation between the second turntable and the second transmission shaft can adjust the horizontal angle of the second cutting knife, making the second cutting knife inclined so that the waste ticket debris is in an irregular shape, greatly increasing the difficulty of splicing, and improving the privacy protection effect and security.

[0026] Preferably, the outer side end of the support frame is rotatably connected with a transmission rotating rod, and the two ends of the transmission rotating rod are connected with bevel gear sets with the same direction. The second turntable and the transmission rotating rod are connected through the bevel gear sets. Transmission gears are arranged at both ends of the transmission rotating rod. The transmission gears and the transmission rotating rod are connected through ratchet components to realize the one-way transmission between the transmission gears and the transmission rotating rod. A transmission rack is fixed to the inner wall of the housing, and the transmission rack is meshed with the transmission gears.

[0027] With the above technical solution, through the cooperation between the transmission rack and the transmission gears, the transmission rotating rod can be driven to perform one-way transmission and rotation when the second cutting knife moves in parallel. The transmission rotating rod uses the bevel gear sets to drive the second turntable to rotate synchronously, so as to realize the continuous angle adjustment of the second cutting knife during reciprocating cutting.

[0028] Preferably, the lower end of the flow guide plate contacts the housing of the collection box. First flow guide grooves are provided on both sides of the flow guide plate. The lower ends of the first flow guide grooves are connected to air inlet filters, and the upper ends of the first flow guide grooves extend into the second motor installation groove. Second flow guide grooves are provided on the upper side surface of the flow guide plate. The second flow guide grooves communicate with the second motor installation groove. An air outlet grille is installed on the side surface of the housing, and the second flow guide grooves are in communication with the outside through the air outlet grille.

[0029] With the above technical solution, through the cooperation of the first flow guide groove and the second flow guide groove, when the impeller rotates to drive air to flow downward in the housing, the air can flow from the first flow guide groove into the second motor installation groove and flow out through the second flow guide groove, which can avoid the air pressure increase inside the housing during continuous cutting and can also achieve the heat dissipation of the second motor.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: The accounting financial waste ticket crushing and processing device with privacy protection can reduce the size of the waste tickets after processing through the multi-directional cutting components, thereby improving the crushing degree of the waste tickets and increasing the difficulty of piecing together the crushed waste tickets. Through multi-stage cutting and angle changes, irregularly shaped paper scraps are generated, significantly improving the privacy protection effect.

[0031] 1. Through the cutting structure with adjustable angle, the cutting angle can be continuously adjusted during cutting. The dynamically adjusted angle generates irregularly shaped and small-sized paper scraps that are difficult to restore, meeting the high-security requirements of accounting financial waste tickets;

[0032] 2. Through the combination of the air flow system and the design of the flow guide grooves, the air flow is used to accelerate the falling of the paper scraps to prevent blockage. The combination of the air flow system and the flow guide grooves reduces the residue of the paper scraps and lowers the maintenance frequency; the air inlet filter and the air outlet grille effectively dissipate heat and extend the service life of the motor.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] Please refer to Figures 1-14, the present invention provides a technical solution: a waste ticket shredding and processing device for privacy protection in accounting and finance, including a housing 1 and a collection box 3 disposed at the bottom for collecting waste paper debris. An "V"-shaped feed inlet 2 is opened at the upper end of the housing 1. A rotating shaft 4 is connected to the upper end of the housing 1. A cutting blade 5 is connected to the outside of the rotating shaft 4. The rear end of the rotating shaft 4 is connected to a first motor 8, and a synchronous gear 7 is fixed to the front end of the rotating shaft 4; a rubber gasket is provided at the bottom of the housing 1 to maintain stability during placement and reduce the large vibration noise generated during use. An inlet 2 with an inclination angle of 15±2° is opened at the upper end of the housing 1 to facilitate the placement of paper; the rotating shaft 4 is rotatably connected to the housing 1, and the front end of the rotating shaft 4 extends to the outside of the housing 1 and is connected to the synchronous gear 7. Two groups of the rotating shaft 4 and the synchronous gear 7 are symmetrically arranged, and the two groups of synchronous gears 7 are meshed with each other. A transparent cover can be installed outside the two groups of synchronous gears 7 to improve the convenience of subsequent maintenance and repair. When in use, the device is started, and the waste tickets to be processed are put into the feed inlet 2. The first motor 8 drives the rotating shaft 4 and the cutting blade 5 to rotate at a high speed, cutting the waste ticket paper into strips. The two groups of synchronous gears 7 can keep the two groups of rotating shafts 4 rotating in opposite directions, and the rotation direction of the cutting blade 5 is reasonably designed to pull the waste ticket downward while cutting the waste ticket; the cutting blades 5 are equidistantly and arrayedly distributed outside the two groups of rotating shafts 4, and the left and right cutting blades 5 are arranged in a staggered manner; an impeller 6 is arranged between two adjacent cutting blades 5, and the impeller 6 is fixed to the rotating shaft 4; the upper end shape of the guide plate 9 is adapted to the cutting blade 5, and a "V"-shaped guide groove is opened in the middle of the guide plate 9; the design of the impeller 6 can rotate synchronously with the rotating shaft 4 and generate a downward air flow during rotation, driving the long strip-shaped waste ticket to move further downward through the guide groove and keeping the long strip-shaped waste ticket in a hanging state to avoid bending and folding, etc.

[0050] A flow guide plate 9 is fixed in the middle of the housing 1. There is a first cutting knife 10 at the lower end of the flow guide plate 9. Second motors 11 are fixed on both sides of the flow guide plate 9. A transmission assembly is connected between the second motors 11 and the first cutting knife 10 to enable the first cutting knife 10 to reciprocally cut the paper. Two groups of first cutting knives 10 are provided. The inner sides of the two groups of first cutting knives 10 are in contact. The two ends of the first cutting knife 10 are slidably connected to the inner wall of the housing 1. The flow guide groove opened at the bottom of the flow guide plate 9 is "V"-shaped with an opening at the bottom, and the opening width is 2-3 mm. To avoid large swings affected by the downward air flow and affecting the cutting effect. After the long strip of waste tickets moves to the lower end of the flow guide groove, they are cut by the two reciprocating first cutting knives 10. And the two groups of first cutting knives 10 are vertically offset and separated, similar to the principle of scissors, and are slidably connected to the inner wall of the housing 1 at both ends to ensure the stable progress of the cutting action. A transmission plate 14 is fixed in the middle on the outer side of the first cutting knife 10. The transmission plate 14 is designed in a "T" shape, and a transmission groove is opened on the outer side of the transmission plate 14. The lower shaft of the second motor 11 extends outside the flow guide plate 9, and a first turntable 12 is fixed at the lower shaft end of the second motor 11. A first transmission shaft 13 is fixed eccentrically at the lower end of the first turntable 12. The lower end of the first transmission shaft 13 extends into the transmission groove. The first transmission shaft 13 slides inside the transmission groove. When the second motors 11 on both sides of the flow guide plate 9 are started and cooperate with the transmission assembly, reciprocating movements in opposite directions of the two groups of first cutting knives 10 can be realized. The second motor 11 rotates to drive the first turntable 12 to rotate. The first transmission shaft 13 rotates following the first turntable 12. The first transmission shaft 13 is connected to the edge of the first turntable 12 to enable circular motion. When the first transmission shaft 13 makes circular motion, it can slide inside the transmission groove and drive the transmission plate 14 and the first cutting knife 10 to make horizontal reciprocating movements. Both groups of second motors 11 are small stepping motors, and the rotation speed can be precisely controlled to enable the two groups of first cutting blades 10 to move inward or outward simultaneously. When the two groups of first cutting blades 10 move inward simultaneously, they cooperate to generate a shearing force to complete the truncation of the long strip of waste tickets into small-sized paper scraps

[0051] A second cutting knife 15 is provided at the lower end of the first cutting knife 10, and a transmission connecting rod 16 is connected between the second cutting knife 15 and the first cutting knife 10. The transmission connecting rod 16 keeps the two cutting structures moving synchronously. A support frame 17 is fixed outside the second cutting knife 15, and an angle adjustment component is connected to the lower end of the support frame 17, which can realize the horizontal angle adjustment of the second cutting knife 15 to achieve the irregular shape crushing of shredded paper. The transmission connecting rods 16 are symmetrically arranged on the front and rear sides of the first cutting knife 10. The upper end of the transmission connecting rod 16 is rotatably connected to the first cutting knife 10. Limiting sliding grooves are provided on the outer sides of the front and rear ends of the second cutting knife 15. A roller is rotatably connected to the lower end of the transmission connecting rod 16, and the roller is slidably matched with the limiting sliding groove. The first cutting knife 10 is the main power input component. When the first cutting knife 10 moves, the second cutting knife 15 is driven to move synchronously by the transmission connecting rod 16. The lower end of the transmission connecting rod 16 is slidably matched with the second cutting knife 15 through the limiting sliding groove, and the two ends are respectively rotatably connected to the first cutting knife 10 and the second cutting knife 15, ensuring that the angle adjustment of the second cutting knife 15 is not restricted and keeping the two cutting knives working in coordination. The inner end of the support frame 17 is rotatably connected to a second turntable 18, and a second transmission shaft 19 is connected to the inner side of the second turntable 18 eccentrically. The second transmission shaft 19 is fixed to the second cutting knife 15. The second turntable 18 and the second transmission shaft 19 are mirror-symmetrically distributed at both ends of the second cutting knife 15. The angle positioning of the second cutting knife 15 can be realized by using the second turntable 18 and the second transmission shaft 19 connected to the outer edge. When the two mirror-symmetrically distributed second turntables 18 rotate in the same direction, because the initial positions of the two second transmission shafts 19 are different but the rotation directions are different, one end of the second cutting knife 15 will move upward and the other end will move downward, thereby realizing the tilting of the knife body and achieving the irregular cutting of strip-shaped waste tickets. Moreover, the left and right two second cutting knives 15 are designed with the same tilting cycle mode to ensure that the two second cutting knives 15 can contact in a staggered manner when moving inward, realizing the shearing of waste tickets.

[0052] A transmission rotating rod 20 is rotatably connected to the outer end of the support frame 17, and bevel gear sets 21 with the same direction are connected to both ends of the transmission rotating rod 20. The second turntable 18 is connected to the transmission rotating rod 20 through the bevel gear set 21. Transmission gears 22 are arranged at both ends of the transmission rotating rod 20, and a transmission rack 23 is fixed to the inner wall of the housing 1. The transmission rack 23 is meshed with the transmission gears 22. When the first cutting knife 10 reciprocates horizontally, the support frame 17 drives the transmission rotating rod 20 and the transmission gears 22 to shift horizontally. When the first cutting knife 10 moves outward, the transmission rack 23 drives the transmission gears 22 and the transmission rotating rod 20 to rotate. The transmission rotating rod 20 uses the cooperation of the bevel gear set 21 to change the transmission direction and drive the second turntable 18 to rotate. The second turntable 18 drives the second transmission shaft 19 to rotate and adjust the angle of the second cutting knife 15. The maximum inclination angle of the second cutting knife 15 is 3-5°. The transmission gear 22 and the transmission rotating rod 20 are connected through a ratchet assembly to achieve one-way transmission between the transmission gear 22 and the transmission rotating rod 20. In order to keep the angle of the second cutting knife 15 able to change cyclically, it is designed that the transmission gear 22 and the transmission rotating rod 20 are connected by a ratchet assembly to achieve one-way transmission. When the second cutting knife 15 moves inward for cutting, the transmission gear 22 idles and will not have a reverse power impact on the transmission rotating rod 20, ensuring the stability and reliability of the angle adjustment mechanism.

[0053] The lower end of the flow guide plate 9 contacts the frame of the collection box 3. First flow guide grooves 24 are formed on both sides of the flow guide plate 9. The lower ends of the first flow guide grooves 24 are connected to an air intake filter screen 26, and the upper ends of the first flow guide grooves 24 extend into the installation groove of the second motor 11. Second flow guide grooves 25 are formed on the side surface of the upper end of the flow guide plate 9. The second flow guide grooves 25 communicate with the installation groove of the second motor 11. An air outlet grille 27 is installed on the side surface of the housing 1. The second flow guide grooves 25 are communicated with the outside through the air outlet grille 27. When the impeller 6 rotates following the rotating shaft 4, it will draw external air into the housing 1 and flow downward, which can guide the paper scraps to smoothly enter the collection box 3. At the same time, it can turn the internal accounting and financial waste ticket scraps. After mixing, the safety is further improved. At the same time, the air entering the collection box 3 can enter the installation groove of the second motor 11 through the first flow guide grooves 24 and then flow out of the housing 1 through the second flow guide grooves 25 again. The air intake filter screen 26 and the air outlet grille 27 can prevent the paper scraps from entering the inner wall of the motor installation groove along with the air flow. Since the second motor 11 is installed inside the flow guide plate 9 and is difficult to dissipate heat, this flow guide structure can achieve efficient and rapid heat dissipation of the second motor 11 and maintain the stability of long-term continuous shredding operation.

[0054] Embodiment 2 is different from Embodiment 1 in the cutting surface shapes of the first cutting knife 10 and the second cutting knife 15. In Embodiment 2, the inner sides of the first cutting knife 10 and the second cutting knife 15 are serrated, which can achieve a better destruction effect when shredding accounting and financial waste tickets. However, the disadvantage is that a certain amount of powdery paper scraps are easily generated during high-speed reciprocating cutting.

[0055] Embodiment 3, which is different from Embodiment 1 in that in the angle adjustment structure, structures such as the first turntable 18, the second transmission shaft 19, and the bevel gear set 21 are provided in a set, which can reduce the equipment cost. However, the angle adjustment range in the same space is reduced, and the change in the paper shape is also relatively reduced, and the reliability and safety are relatively reduced.
