Description

Technical Field

[0001] This invention relates to the field of document shredding, and in particular to a document shredding device for enterprise management. Background Technology

[0002] In the daily operations of enterprises, contracts, financial documents, customer information, internal decision-making documents and other documents contain a large amount of sensitive information. Once this information is leaked, it may lead to the leakage of trade secrets, damage to customer privacy, and even legal disputes and economic losses. Therefore, thoroughly shredding these documents is a core aspect of enterprise information security management.

[0003] Current paper shredders on the market have many undeniable shortcomings. Most are limited in function, only capable of basic shredding and unable to handle plastic products such as PP folders and PET plastic wrap embedded in documents. These impurities accelerate blade wear, cause equipment malfunctions, and increase maintenance costs. At the same time, traditional equipment lacks sufficient shredding precision, and coarse fragments are easily pieced together, resulting in limited confidentiality and failing to meet the needs of high-security industries. Furthermore, separating mixed paper and plastic fragments after shredding is difficult, leading to high manual sorting costs, low resource recycling rates, and low automation levels. Loose shredded paper collection relies on manual labor, and frequent cleaning reduces efficiency. Some high-end equipment is also complex and expensive due to its over-reliance on electronic control systems, making it difficult to popularize in small and medium-sized enterprises.

[0004] Chinese Patent Publication No. CN112387360A discloses a waste disposal device for shredding documents in enterprise management. A support is slidably installed inside the movable base, extending through a partition. A filter screen is fixedly installed at the inner end of the support. A baffle is installed inside the filter screen via a torque spring. An inclined plate is fixedly installed below the filter screen on the surface of the partition, and a collection seat is located below the inclined plate. When the paper paste moistened by water accumulates inside the filter screen to a certain weight, it presses the support to move downward inside the movable base. When the movable base moves downward with the moving rod, the protrusion at the bottom of the inclined plate can push open the baffle. Simultaneously, the support squeezes the bottom block, causing the collection seat to aggregate, thus allowing the paper paste in the filter screen to fall into the collection seat. The paper paste re-aggregates between the hemispherical holes, forming a clump. After opening, it is discharged through the discharge pipe, avoiding internal blockage and preventing the shredded paper from being blown apart, facilitating subsequent recycling. However, the aforementioned device cannot separate paper scraps from plastic during use, and the shredded material is inconvenient for subsequent storage and transportation. Summary of the Invention

[0005] The main objective of this invention is to provide a document shredding and processing device for enterprise management, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A document shredding device for enterprise management includes a housing. A first shredding mechanism is installed at the upper end of the housing, and a guide plate is provided at the lower end of the first shredding mechanism. A separation component is provided in the upper part of the inner cavity of the housing. The separation component includes two vertically distributed filter plates, both located below the discharge port of the first shredding mechanism. The two filter plates are driven by the power source of the first shredding mechanism to sieve paper or plastic. Both filter plates are tilted to the right. A collection component for collecting plastic is installed at the right end of the upper part of each of the two filter plates. A dispersing component for breaking up document fragments is provided at the lower end of the lower filter plate. The dispersing component includes rotating blades. During the swinging process of the lower filter plate, the rotating blades in the dispersing component will rotate. A second shredding mechanism for secondary document shredding is provided below the dispersing component. A pressing component for pressing paper scraps into bricks and a feeding component for collecting paper bricks are provided at the lower end of the second shredding mechanism. The pressing component can simultaneously enable the feeding component to automatically collect the paper bricks during operation.

[0007] The separation assembly also includes a rotating shaft. The right end of the rotating shaft is connected to the power source of the shredder mechanism via a belt drive mechanism. The left end of the rotating shaft extends into the inner cavity of the outer casing and is fixedly connected to an eccentric wheel. The outer surface of the eccentric wheel continuously strikes the two filter plates that are close to each other. The upper ends of the two filter plates are provided with rubber that allows plastic fragments to bounce up. The filter holes on the outer surface of the upper filter plate have a larger diameter than those on the outer surface of the lower filter plate. The inner surfaces of the filter holes of the two filter plates are movably connected to several anti-clogging frames. The anti-clogging frames are all inverted cone shape, and the diameters of the upper and lower ends of the anti-clogging frames are smaller than the filter holes on the surface of the filter plate that are adapted to their positions. A movable door is provided on the outer surface of the outer casing at a position corresponding to the filter plate.

[0008] The left end of the anti-clogging frame is fixedly connected to a connecting frame. The side of the connecting frame away from the anti-clogging frame is fixedly connected to the outer shell. The lower end of the filter plate located on the lower side is fixedly connected to several elastic elements. The lower ends of the several elastic elements are jointly fixedly connected to a fixing plate. The right end of the fixing plate is fixedly connected to the inner wall of the outer shell.

[0009] The collection assembly includes a guide block fixedly connected to the right end of the upper side of the filter plate. A collection box for collecting plastic is slidably connected to the outer surface of the guide block. The opening of the collection box faces left, and a baffle is fixedly connected to the upper end of the collection box located on the upper side.

[0010] The upper end of the collection box located on the lower side is fixedly connected to a telescopic plate that always keeps in close contact with the lower end of the filter plate located on the upper side.

[0011] The dispersing assembly also includes a fixing rod, a fixing ring, and a rotating shaft. The fixing ring is fixedly connected to the rear side wall of the inner surface of the outer shell via the fixing rod. The inner surface of the fixing ring is rotatably connected to a rotating shaft that can drive the rotating blades to rotate. The outer surface of the rotating shaft is provided with an arc-shaped guide groove. The upper end of the fixing ring is fixedly connected to a lifting block that is in close contact with the lower end of the filter plate below via a spring. The lower side of the inner surface of the lifting block is fixedly connected to a ball bearing that is slidably connected to the arc-shaped guide groove. When the filter plate below swings, it will drive the lifting block and the ball bearing to move up and down continuously. When the ball bearing reciprocates once in the inner surface of the arc-shaped guide groove, it can drive the rotating shaft to rotate one revolution. The outer surface of the lifting block is slidably connected to a fixing frame that can limit its own position. The rear end of the fixing frame is fixedly connected to the rear side wall of the inner surface of the outer shell. The outer surface of the lifting block is provided with a sliding groove that matches the protrusion on the inner surface of the fixing frame.

[0012] Preferably, the extrusion assembly includes a through groove on the lower left side of the inner surface of the outer shell, a hydraulic device is installed on the lower left side of the inner cavity of the outer shell, and an L-shaped pusher block that can extrude paper scraps into bricks is fixedly installed at the output end of the hydraulic device. When the upper end of the L-shaped pusher block is controlled by the through groove to retract, it will slide in contact with the through groove. A shaping box that can shape paper scraps is provided on the lower right side of the inner surface of the outer shell. The L-shaped pusher block pushes the paper scraps accumulated at the bottom of the outer shell toward the inner surface of the shaping box for extrusion.

[0013] Preferably, the feeding assembly includes a sliding groove and a feeding port at the lower end of the outer shell. A collection box for collecting paper bricks is fixedly connected to the lower end of the outer shell. A movable door II is provided on the outer surface of the outer shell at a position corresponding to the collection box. A connecting frame II is fixedly connected to the lower left side of the L-shaped push block, and the outer surface of the connecting frame II is slidably connected to the sliding groove. A rack I is fixedly connected to the upper right side of the connecting frame II. A plurality of elastic elements II are fixedly connected to the right end of the collection box. The right ends of the plurality of elastic elements II are jointly fixedly connected to a movable baffle that is slidably connected to the inner surface of the outer shell.

[0014] Preferably, the lower end of the collection box is fixedly connected to two fixed blocks distributed front and back. The rear end of the fixed block located on the front side is rotatably connected to a gear that meshes with a rack. The rear side of the gear is rotatably connected to a one-way shaft. The rear end of the one-way shaft is fixedly connected to a rotating shaft that is rotatably connected to the fixed block located on the rear side. The lower end of the movable baffle is fixedly connected to two racks distributed front and back. The outer surface of the rotating shaft is fixedly connected to two gears that mesh with the racks.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the cooperation of various components, can simultaneously separate documents from plastic during document crushing using separation and collection components. This avoids interference from plastic impurities in subsequent crushing stages. During the separation process, the rotating blades are driven to rotate, dispersing shredded paper from the same document to different locations and thoroughly mixing it with shredded paper from other documents, thus improving the information security of the shredded documents. Finally, the extrusion and feeding components compress the shredded documents into paper bricks, achieving automatic feeding while facilitating subsequent storage and transportation. Overall, this invention saves labor costs, avoids potential information leakage risks, and improves the overall operating efficiency of the equipment.

[0016] 2. This invention, through the cooperation of a shredding mechanism, a separation component, a collection component, and a dispersing component, can separate the shredded paper and plastic during document shredding using two tilting, swinging filter plates. Utilizing the difference in elasticity, the plastic particles bounce multiple times and then gather in the collection box on the right, providing pure shredded paper raw materials for subsequent processing. Throughout the process, the filter holes remain unobstructed, and the up-and-down swinging of the filter plates causes the rotating blades to rotate, forcibly mixing the initially shredded paper and breaking up the regional aggregation of fragments from the same document. This effectively prevents the fragments from being pieced together and restores the original document, enhancing the confidentiality and security of enterprise document management.

[0017] 3. This invention, through the cooperation of the extrusion component and the feeding component, enables the L-shaped pusher block to compress loose paper scraps that occupy a large space into paper bricks with a significantly reduced volume, facilitating subsequent storage and transportation. Simultaneously, the movement trajectory of the L-shaped pusher block is used to control the opening and closing of the feeding port, thereby controlling the automatic feeding of the paper bricks. The entire process requires no manual intervention, allowing enterprises to efficiently complete document shredding and subsequent processing while ensuring document security.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figure 1-2 As shown, a document shredding device for enterprise management includes a housing 1. The upper end of the housing 1 is equipped with a shredding mechanism 2 for preliminary shredding of paper or plastic. The plastic in the documents is generally a document bag cover, plastic binder, ID card sleeve, binding strip, hot melt glue-sealed spine, etc. The lower end of the shredding mechanism 2 is provided with a guide plate 21. The upper part of the inner cavity of the housing 1 is provided with a separation component 3. Specifically, the separation component 3 includes two vertically distributed filter plates 33, and both filter plates 33 are located below the discharge port of the shredding mechanism 2.

[0022] During use, both filter plates 33 are driven by the power source of the paper shredding mechanism 2 to sieve paper or plastic. Both filter plates 33 are tilted to the right. The upper right end of both filter plates 33 is equipped with a collection component 4 for collecting plastic. The lower end of the lower filter plate 33 is equipped with a dispersing component 5 that can break up document fragments. The dispersing component 5 includes rotating blades 55. During use, the lower filter plate 33 swings and drives the rotating blades 55 in the dispersing component 5 to rotate. The lower side of the dispersing component 5 is equipped with a secondary paper shredding mechanism 6 for shredding documents. The paper shredding mechanism 6 only processes clean shredded paper, which can extend the service life of the blades. At the same time, after the shredded paper enters the paper shredding mechanism 6, it can be shredded more evenly, improving the shredding quality and making the final shredding effect more in line with high confidentiality requirements. The lower end of the paper shredding mechanism 6 is equipped with a pressing component 7 that presses the paper scraps into bricks and a feeding component 8 that collects the paper bricks. When the pressing component 7 is running, it can simultaneously enable the feeding component 8 to complete the automatic collection of the paper bricks.

[0023] The paper shredding mechanism 1 2 and paper shredding mechanism 2 6 mentioned above are both existing technologies. The paper inlet is equipped with an infrared sensor and an emergency switch, which will stop the machine when a person approaches or abnormal feeding occurs. The cutting blade assembly has overload protection. When paper scraps accumulate or hard objects are mixed in, the paper will automatically reverse and be ejected to prevent jamming. The motor is equipped with a sensor, and an indicator light will alarm when there is an abnormality. These safety protections (such as sensor switches and overload protection) and maintenance structures are all conventional configurations in existing technologies, so they will not be described in detail in this solution. The document first enters the shredding mechanism 2, where it is initially cut into fragments by interlaced serrated blades. Then, the shredded paper enters the shredding mechanism 6, where it is further pulverized into smaller fragments by finer blades.

[0024] Therefore, this solution, through the cooperation of various components, can simultaneously separate the document from the plastic using the separation component 3 and the collection component 4 while crushing the document, avoiding interference from plastic impurities in the subsequent crushing process. During the separation process, the rotating blade 55 is driven to rotate, so that the shredded paper belonging to the same document is dispersed to different positions and fully mixed with the shredded paper of other documents, improving the information security of the shredded document. Finally, the extrusion component 7 and the feeding component 8 are used to compress the shredded document into paper bricks, completing automatic feeding while also facilitating subsequent storage and transportation. Overall, it saves labor costs, avoids the risk of potential information leakage, and improves the overall operating efficiency of the equipment.

[0025] Example 2 is based on Example 1, and aims to achieve the effect of separating and breaking up paper and plastic after the documents have been broken.

[0026] See Figure 3-5The separating assembly 3 also includes a rotating shaft 31. The right end of the rotating shaft 31 is connected to the power source of the shredding mechanism 2 via a belt drive mechanism. The left end of the rotating shaft 31 extends into the inner cavity of the outer casing 1 and is fixedly connected to an eccentric wheel 32. The outer surface of the eccentric wheel 32 continuously strikes the side of the two filter plates 33 that are close to each other, causing the two filter plates 33 to swing up and down alternately. The upper ends of the two filter plates 33 are provided with rubber that allows plastic fragments to bounce up. The filter holes on the outer surface of the upper filter plate 33 have a larger diameter than those on the lower filter plate 33. The filter holes on the surface are of various sizes. The inner surfaces of the filter holes of the two filter plates 33 are movably connected to several anti-clogging brackets 35. The anti-clogging brackets 35 are all inverted cones, and the diameters of the upper and lower ends of the anti-clogging brackets 35 are smaller than the filter holes on the surface of the filter plate 33 that are adapted to their positions. The outer surface of the outer shell 1 is provided with a movable door corresponding to the position of the filter plate 33, so that the anti-clogging brackets 35 can move back and forth in the filter holes of the upper and lower filter plates 33. During the movement, the filter holes of the filter plates 33 remain unobstructed and will not be blocked by the anti-clogging brackets 35.

[0027] Furthermore, the belt drive mechanism includes two pulleys and belts of different diameters, wherein the pulley connected to the rotating shaft 31 has a smaller diameter, and thus the rotational speed of the rotating shaft 31 is greater than the rotational speed of the power source of the shredder mechanism 2. The anti-clogging frame 35 is made of rubber. During the swinging process, the aperture of the filter plate 33 will continuously contact the anti-clogging frame 35. The rubber anti-clogging frame 35 will not cause damage or conflict with the filter plate 33.

[0028] Even when the filter plate 33 is being struck and shaken, its overall tilt angle remains tilted to the right, which makes it easy for plastic fragments to always gather to the right.

[0029] A connecting frame 34 is fixedly connected to the left end of the anti-blocking frame 35. The side of the connecting frame 34 away from the anti-blocking frame 35 is fixedly connected to the outer shell 1. Several elastic elements 36 are fixedly connected to the lower end of the filter plate 33 located on the lower side. The lower ends of the several elastic elements 36 are fixedly connected to a fixing plate 37. The right end of the fixing plate 37 is fixedly connected to the inner wall of the outer shell 1.

[0030] Next, the documents used for enterprise management are placed into the shredder 2. The shredder 2 is started to begin preliminary shredding of the documents. During shredding, the rotating shaft 31 also rotates synchronously, causing the eccentric wheel 32 to continuously and alternately strike the two filter plates 33. The upper filter plate 33 will fall back to its original position due to gravity the moment it separates from the eccentric wheel 32, always sticking to the telescopic plate 44. The lower filter plate 33 will squeeze the lower elastic element 36 when it comes into contact with the eccentric wheel 32, and will be lifted back to its original position by the elasticity of the elastic element 36 when it separates from the eccentric wheel 32. It is repeatedly struck by the eccentric wheel 32, causing the plastic fragments that fall on the surface of the filter plate 33 to be continuously bounced up and eventually enter the collection box 42 as the filter plate 33 tilts. Simultaneously, during the reciprocating lifting and lowering of the two filter plates 33, the anti-clogging frame 35 will continuously move back and forth on the filter holes on the surface of the two filter plates 33, thereby eliminating the possibility of the filter holes of the filter plates 33 being blocked.

[0031] The oscillation of the filter plate 33 ensures that the shredded paper has sufficient momentum to move towards the filter holes under the action of gravity, while preventing the plastic particles from slipping off too quickly. When the mixture of shredded paper and plastic particles falls onto the filter plate 33, the shredded paper, being relatively small, usually has a length and width within the allowable range of the filter holes. With the assistance of gravity and the vibration generated by the oscillation of the filter plate 33, it passes smoothly through the filter holes and falls down. However, larger and more elastic plastic particles, such as the blocky particles after shredding PP folders or fragments of PET plastic film, are significantly larger than the filter holes. When they collide with the filter plate 33, the plastic particles are bounced up because the surface of the filter plate 33 is made of rubber. During the repeated bounces, the plastic particles gradually move to the right under the combined force of gravity and the direction of bounce, and eventually enter the collection box 42.

[0032] See Figure 4-5 The collection component 4 includes a guide block 41 fixedly connected to the right end of the upper side of the filter plate 33. A collection box 42 for collecting plastic is slidably connected to the outer surface of the guide block 41. The opening of the collection box 42 faces left, so that the plastic intercepted by the right-tilting filter plate 33 can be smoothly ejected into the collection box 42. A baffle 43 is fixedly connected to the upper end of the collection box 42 located on the upper side.

[0033] Furthermore, the upper baffle 43 can block the popped-up plastic fragments, allowing them to enter the upper collection box 42 under the obstruction of the baffle 43.

[0034] The upper end of the collection box 42 located on the lower side is fixedly connected to a telescopic plate 44 that always keeps in close contact with the lower end of the filter plate 33 located on the upper side. The telescopic plate 44 has an elastic structure inside, so that even if the filter plate 33 on the upper side is lifted up, the telescopic plate 44 will not separate from it.

[0035] Furthermore, the lower telescopic plate 44 can also block the popped-up plastic fragments. However, the telescopic plate 44 is equipped with a spring, which can ensure that the upper end of the telescopic plate 44 is always in contact with the upper filter plate 33, so as to prevent the two filter plates 33 from creating gaps during alternating swings, thus preventing this part of the plastic from entering the collection box 42.

[0036] See Figure 6-7 The dispersing assembly 5 also includes a fixing rod 51, a fixing ring 52, and a rotating shaft 53. The fixing ring 52 is fixedly connected to the rear side wall of the inner surface of the outer shell 1 via the fixing rod 51. The inner surface of the fixing ring 52 is rotatably connected to the rotating shaft 53, which can drive the rotating blade 55 to rotate. The outer surface of the rotating shaft 53 is provided with an arc-shaped guide groove 531. The upper end of the fixing ring 52 is fixedly connected to a lifting block 54 that is in close contact with the lower end of the filter plate 33 via a spring. The spring can keep the lifting block 54 in contact with the lower filter plate 33, thereby facilitating the filter plate 33 to drive the lifting block 54 to slide up and down. The lower side of the inner surface of the lifting block 54 is fixedly connected to the... A ball bearing 541 is slidably connected to the arc-shaped guide groove 531. During use, the filter plate 33 located on the lower side will drive the lifting block 54 and the ball bearing 541 to move up and down continuously during the swing. When the ball bearing 541 moves up and down once on the inner surface of the arc-shaped guide groove 531, it can drive the rotating shaft 53 to rotate one revolution, thereby achieving the effect of rotating the rotating blade 55 to disperse the paper scraps. The outer surface of the lifting block 54 is slidably connected to a fixing frame 521 that can limit its own position, so that the lifting block 54 can only move up and down under the drive of the filter plate 33 and cannot rotate. The rear end of the fixing frame 521 is fixedly connected to the rear side wall of the inner surface of the outer shell 1.

[0037] Furthermore, when the eccentric wheel 32 strikes the two filter plates 33, it causes the filter plates 33 to swing up and down. The vertical distance of the up and down swing of the filter plates 33 is equal to the height of the arc-shaped guide groove 531.

[0038] The outer surface of the lifting block 54 is provided with a sliding groove that matches the protrusion on the inner surface of the fixing frame 521, which facilitates the limiting of the lifting block 54 so that it can only move vertically up and down.

[0039] Furthermore, as the filter plate 33 on the lower side swings, it continuously presses the lifting block 54 below to move up and down, causing the ball bearing 541 to slide continuously in the arc-shaped guide groove 531, driving the rotating shaft 53 to rotate as a whole, thereby driving the rotating blade 55 to rotate.

[0040] Rotating blade 55 disperses the shredded paper in different directions. For the same document, the fragments that might have gathered together due to the initial feeding state are randomly scattered to different positions after being scrambled by rotating blade 55. This effectively avoids the possibility of the fragments being pieced back together and greatly improves the security of document destruction.

[0041] Therefore, this solution, through the cooperation of the shredding mechanism 2, the separation component 3, the collection component 4, and the dispersing component 5, can separate the shredded paper and plastic by using two tilting and swinging filter plates 33 during the shredding process. The elastic difference causes the plastic particles to gather in the collection box 42 on the right after multiple bounces, providing pure shredded paper raw materials for subsequent processing. The filter holes are kept open throughout the process, and the up-and-down swing of the filter plates 33 causes the rotating blades 55 to rotate, forcibly mixing the initially shredded paper and breaking the regional aggregation of fragments from the same document. This effectively avoids the possibility of fragments being pieced together and restores, enhancing the confidentiality and security of enterprise document management.

[0042] Example 3 is based on Examples 1 and 2, and aims to compress paper scraps into paper bricks that are easy to store and recycle.

[0043] See Figure 8-10 The extrusion assembly 7 includes a through groove 72 on the lower left side of the inner surface of the outer shell 1. A hydraulic device 73 is installed on the lower left side of the inner cavity of the outer shell 1. An L-shaped pusher 74 that can compress paper scraps into bricks is fixedly installed at the output end of the hydraulic device 73. When the upper end of the L-shaped pusher 74 is controlled by the through groove 72 to retract, it will slide against the through groove 72 to push down the paper scraps accumulated on the upper end of the L-shaped pusher 74. A shaping box 75 that can shape paper scraps is provided on the lower right side of the inner surface of the outer shell 1. The L-shaped pusher 74 pushes the paper scraps accumulated at the bottom of the outer shell 1 to the inner surface of the shaping box 75 and compresses them, so that the paper scraps fill the inner cavity of the shaping box 75. Through strong pressure, the paper scraps are compressed into dense paper bricks. That is, the loose paper scraps that originally occupied a large space are compressed into bricks with a significantly reduced volume, which not only facilitates storage and transportation and reduces the company's need for storage space, but also makes the shape and size of the paper bricks easy to recycle.

[0044] The feeding assembly 8 includes a sliding groove 81 and a feeding port 82 at the lower end of the outer shell 1. A collection box 83 for collecting paper bricks is fixedly connected to the lower end of the outer shell 1. A movable door 2 is provided on the outer surface of the outer shell 1 at a position corresponding to the collection box 83. A connecting frame 2 84 is fixedly connected to the lower left side of the L-shaped push block 74, and the outer surface of the connecting frame 2 84 is slidably connected to the sliding groove 81. A rack 1 85 is fixedly connected to the upper right side of the connecting frame 2 84. A plurality of elastic elements 2 86 are fixedly connected to the right end of the collection box 83. A movable baffle 87 that is slidably connected to the inner surface of the outer shell 1 is fixedly connected to the right end of the plurality of elastic elements 2 86.

[0045] See Figure 11The lower end of the collection box 83 is fixedly connected to two fixed blocks 88 distributed front and back. The rear end of the fixed block 88 on the front side is rotatably connected to a gear 89 that meshes with a rack 85. The rear side of the gear 89 is rotatably connected to a one-way shaft 810. The rear end of the one-way shaft 810 is fixedly connected to a rotating shaft 811 that is rotatably connected to the fixed block 88 on the rear side. The lower end of the movable baffle 87 is fixedly connected to two racks 813 distributed front and back. The outer surface of the rotating shaft 811 is fixedly connected to two gears 812 that mesh with the racks 813.

[0046] Furthermore, the one-way shaft 810 mentioned above can only rotate clockwise under the drive of gear 89. When gear 89 rotates counterclockwise, the one-way shaft 810 remains stationary. Subsequently, after a large amount of paper scraps accumulate inside the outer casing 1, the hydraulic device 73 is activated to drive the L-shaped pusher 74 to move to the right, pushing the paper scraps into the molding box 75 and squeezing them forcefully, so that the scraps in the molding box 75 become paper bricks. Then, the hydraulic device 73 controls the L-shaped pusher 74 to reset to the left. During the process, the broken paper scraps above continue to fall and accumulate on the upper end of the L-shaped pusher 74. During the reset process, the L-shaped pusher 74 will pass through the through groove 72, so that the paper scraps accumulated on its surface will be pushed down, making it easier to squeeze again. Synchronously, when the L-shaped pusher 74 moves to the right, it drives the connecting frame 84 to move as well, causing the rack 85 to mesh with the gear 89, which in turn causes the gear 89 to rotate counterclockwise. However, in this state, the one-way shaft 810 is stationary and the discharge port 82 is closed. Subsequently, when the connecting frame 84 is driven to the left by the L-shaped pusher 74, the gear 89 will be driven to rotate clockwise, causing the one-way shaft 810, the rotating shaft 811, and the gear 812 to rotate clockwise together. When rack 812 meshes with rack 813, the movable baffle 87 moves to the right, opening the feed port 82. The compressed paper bricks fall directly into the collection box 83. However, when rack 85 separates from gear 89, gear 89 loses its limit and is compressed by elastic element 86, the movable baffle 87 resets. In this state, the one-way shaft 810, rotating shaft 811, gear 812, and gear 89 will rotate freely, thus achieving the effect of automatically closing the feed port 82.

[0047] Therefore, this solution, through the cooperation of the extrusion component 7 and the feeding component 8, enables the L-shaped pusher 74 to compress loose paper scraps that occupy a large space into paper bricks with a significantly reduced volume, facilitating subsequent storage and transportation. Simultaneously, the movement trajectory of the L-shaped pusher 74 controls the opening and closing of the feeding port 82, thereby controlling the automatic feeding of the paper bricks. The entire process requires no manual intervention, allowing enterprises to efficiently complete document shredding and subsequent processing while ensuring document security.

[0048] It should be noted that the specific installation method, circuit connection method and control method of the paper shredding mechanism 1 2, paper shredding mechanism 2 6 and hydraulic device 73 used in this invention are all conventional designs, and will not be described in detail in this invention.
