Description

Technical Field

[0001] The present invention belongs to the technical field of file processing devices, and in particular is a legal document confidentiality processing device and a use method thereof. Background Art

[0002] A legal document refers to a document that has legal effect and needs to be kept confidential. When the document expires, it needs to be kept confidential. The reasons for keeping legal documents confidential mainly include protecting national security, personal privacy and business secrets, and preventing negative impacts caused by information leakage.

[0003] When dealing with legal documents, the most common way is to use a shredder to shred confidential documents. Shredders are mainly divided into two types: blade-type and roller-type. The former cuts paper into small pieces by blades, while the latter shreds paper by the friction of rollers. A shredder is an office device that can efficiently and safely shred paper documents to prevent information leakage. Shredders usually have a high security level and powerful shredding capabilities, and are suitable for places that require confidentiality, such as government agencies, financial institutions, and large enterprises. By processing paper, confidential information can be effectively protected from being leaked.

[0004] At present, when using a shredder to process legal documents, the documents need to be inserted into the shredder from the feed port one by one. The documents entering the shredder will come into contact with the rotating shredder blade, which will shred and destroy the documents, effectively protecting confidential information from being leaked.

[0005] However, when using a shredder to destroy documents, common shredders can only cut shredded paper into specific shapes, such as strips or blocks, and the shredded paper of each shape is the same size, and the shredded paper will be regularly stacked in the collection bin, so there is still a certain risk of leakage.

DETAILED DESCRIPTION

[0060] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0061] Embodiment 1: Figures 1 to 9 As shown, on the one hand, the present invention discloses a legal document confidentiality processing device, including a shredder; the shredder includes a body 1; a paper inlet 11 is opened on the top of the body 1;

[0062] A crushing mechanism is installed in the machine body 1 below the paper inlet 11; a first collecting bin 12 is provided below the crushing mechanism, and the first collecting bin 12 is a pull-out type;

[0063] The pulverizing mechanism comprises two cutter shafts, namely a first cutter shaft 2 and a second cutter shaft 21;

[0064] Side plates 22 are provided at both ends of the two blade shafts, and both blade shafts are rotatably mounted on the side plates 22, and both sides of the side plates 22 are fixedly mounted in the machine body 1;

[0065] Multiple groups of evenly arranged crushing components are fixedly mounted on the two knife shafts, and the crushing components on the two knife shafts are staggered;

[0066] Each of the crushing assemblies comprises a plurality of cutting knives 23, and the plurality of cutting knives 23 on each set of crushing assemblies are circumferentially mounted on a knife shaft;

[0067] The two knife shafts are fixedly mounted with mutually meshing first gears 24; a second gear 25 meshing with the first gear 24 is mounted below one of the first gears 24, and the second gear 25 is driven by a first motor 26, which is mounted on the machine body 1;

[0068] A cutting mechanism is installed on the two knife shafts, and the cutting assembly is used to cut paper, and the shape of the shredded paper cut out is different from the shape of the shredded paper cut out by the cutting knife 23;

[0069] In this embodiment, the cutting mechanism includes an extrusion component and a cutting component;

[0070] A plurality of extrusion assemblies are installed on the first blade shaft 2, and the extrusion assemblies are arranged alternately with the crushing assemblies on the first blade shaft 2; each group of the extrusion assemblies includes a plurality of extrusion shafts 3, and the plurality of extrusion shafts 3 on each group of the extrusion assemblies are installed around the first blade shaft 2, and the extrusion shafts 3 are arranged alternately with the plurality of cutting knives 23;

[0071] The end surface of each of the extrusion shafts 3 away from the first knife shaft 2 is an arc surface, and the diameter of the arc surface is the same as the diameter of the knife shaft;

[0072] The second blade shaft 21 is provided with a plurality of cutting assemblies, and the cutting assemblies are arranged alternately with the crushing assemblies on the second blade shaft 21; each of the cutting assemblies comprises a plurality of slotted cylinders 4, and the plurality of slotted cylinders 4 on each of the cutting assemblies are arranged around the second blade shaft 21, and the slotted cylinders 4 are arranged alternately with the plurality of cutting knives 23;

[0073] The end surface of each slotting cylinder 4 away from the second knife shaft 21 is an arc surface, and the diameter of the arc surface is the same as the diameter of the knife shaft;

[0074] When the extrusion shaft 3 on the first cutter shaft 2 and the slotting cylinder 4 on the second cutter shaft 21 rotate to the opposite side, the arc surfaces on the extrusion shaft 3 and the slotting cylinder 4 will gradually fit together, and the paper will be cut into discs during the fitting process;

[0075] Specifically, when destroying documents, the shredder is first started, the first motor 26 drives the second gear 25 to rotate, and the rotating second gear 25 drives the first gear 24 to rotate. Since the first gears 24 on the two cutter shafts are meshed with each other, the two cutter shafts are driven to rotate, and the first cutter shaft 2 rotates clockwise, and the second cutter shaft 21 rotates counterclockwise. The two cutter shafts drive the cutting knives 23 on the cutter shafts to rotate, and then the documents are put into the paper feed port 11 in sequence. The documents put into the paper feed port 11 will extend between the two cutter shafts, and the rotating cutter shafts will drive the documents to move downward. When the cutting knife 23 contacts the documents, the cutting knife 23 will cut the documents into block-shaped shredded paper, so that the documents can be shredded and destroyed. At the same time, when the documents pass between the two cutter shafts, the cutting mechanism rotating with the two cutter shafts will also cut the documents. The shredded paper cut by the cutting knife 23 will fall into the first collection bin 12, and then the staff can collect the shredded paper in the first collection bin 12.

[0076] More specifically, when the cutting mechanism cuts the document, the first cutter shaft 2 drives the uniformly arranged extrusion shaft 3 to rotate, and the second cutter shaft 21 drives the uniformly arranged slotted cylinder 4 to rotate. Since the document extends between the two cutter shafts, when the extrusion shaft 3 and the slotted cylinder 4 gradually rotate to the opposite side, the extrusion shaft 3 and the slotted cylinder 4 gradually approach each other, and the document is located between the extrusion shaft 3 and the slotted cylinder 4. When the extrusion shaft 3 and the slotted cylinder 4 approaching each other come into contact, as the arc surfaces on the extrusion shaft 3 and the slotted cylinder 4 gradually fit together, and the document is squeezed by the extrusion shaft 3 and the slotted cylinder 4, the slotted cylinder 4 is pressed against the extrusion shaft 3. 4 will cut the documents passing through, and the cut shredded paper is in the shape of round sheets. After the extrusion shaft 3 and the slotted cylinder 4 cut the documents, the extrusion shaft 3 and the slotted cylinder 4 will gradually separate, and then the cutting knife 23 located above the extrusion shaft 3 and the slotted cylinder 4 will continue to cut the documents and cut the documents into blocks. Then the next extrusion shaft 3 and the slotted cylinder 4 that fit each other will cut the documents moving down again, and the cycle will be repeated, so that the documents can be cut into shredded paper of different shapes, thereby increasing the difficulty of document assembly, improving the confidentiality of the documents, and avoiding leakage;

[0077] Furthermore, when the document processing is completed, the staff turns off the shredder, then pulls out the first collection bin 12 from the machine body 1, and then cleans up the collected shredded paper;

[0078] Furthermore, by providing mutually cooperating extrusion shafts 3 and slotted cylinders 4, when a document is inserted between the relative extrusion shafts 3 and slotted cylinders 4, the mutually fitting extrusion shafts 3 and slotted cylinders 4 will cut the passing document into discs, thereby enabling the document to be cut into blocks and discs at one time, and the sizes of the two shapes of shredded paper are different. Therefore, if some lawless elements want to restore the document, it will increase the difficulty of document assembly, thereby improving the confidentiality of the document and avoiding the leakage of the document.

[0079] Embodiment 2: Both of the two blade shafts are hollow shafts; a conduit 31 is slidably connected inside the first blade shaft 2, and one end of the conduit 31 extends to one side of the first motor 26 and is fixedly mounted on the machine body 1; an air pump 32 is installed on one side of the conduit 31 extending to the first motor 26, and an air outlet pipe of the air pump 32 is connected to the conduit 31;

[0080] The other end of the conduit 31 passes through the first blade shaft 2 and extends to the other side of the machine body 1 and is fixedly mounted on the machine body 1, and the other end of the conduit 31 is closed;

[0081] The conduit 31 is provided with evenly arranged air outlet holes 33 on one side facing the second blade shaft 21, and the air outlet holes 33 are all inclined downward; the number of the air outlet holes 33 is the same as the number of the extrusion components;

[0082] Each of the extrusion shafts 3 is provided with a slide groove 34 on one side close to the first blade shaft 2 and located inside the first blade shaft 2; an air inlet hole 35 is provided on one side of the slide groove 34 close to the conduit 31;

[0083] A top shaft 36 is slidably connected in the slide groove 34 via a spring; a through hole 301 is opened in the extrusion shaft 3; the top shaft 36 extends into the through hole 301;

[0084] The slotting cylinder 4 has a side facing the second blade shaft 21 and a long slot 41 in the second blade shaft 21, and the long slot 41 is connected to the inner cavity of the second blade shaft 21;

[0085] The second blade shaft 21 has an auger shaft 42 rotatably mounted in its inner cavity, and the auger shaft 42 extends out of the machine body 1 on a side close to the first motor 26 and is driven by a second motor 43, which is mounted on the machine body 1.

[0086] The other side of the auger shaft 42 extends out of the machine body 1 ; a discharge trough 44 is provided on the machine body 1 , and the auger shaft 42 extends out of the discharge trough 44 ;

[0087] The discharge chute 44 is located on the side wall of the machine body 1 and a collection box 5 is fixedly installed;

[0088] Specifically, since both blade shafts are hollow shafts, and the conduit 31 provided in the first blade shaft 2 is fixedly installed on the machine body 1, the first blade shaft 2 will rotate along the conduit 31 during the rotation of the first blade shaft 2. When the paper shredder is started, the air pump 32 is also controlled to start. The air pump 32 can draw external air into the conduit 31. Since the other end of the conduit 31 is closed, the gas in the conduit 31 is in a compressed state. During the process of the first blade shaft 2 driving the extrusion shaft 3 to rotate, the top shaft 36 in the slide groove 34 will also be driven to rotate. When the extrusion shaft 3 is completely fitted with the slotting cylinder 4, the two blade shafts respectively drive the extrusion shaft 3 and the slotting cylinder 4 to gradually separate. During the process, the air inlet 35 on the chute 34 will overlap with the air outlet 33 on the conduit 31, so the gas in the conduit 31 will enter the air inlet 35 through the air outlet 33, and then enter the chute 34. When the gas enters the chute 34, it will push the top shaft 36 to slide in the chute 34. At the same time, the top shaft 36 will gradually compress the spring. During the sliding process of the top shaft 36, it will gradually extend into the slotted cylinder 4. At the same time, the top shaft 36 will push the disc-shaped shredded paper cut by the slotted cylinder 4 to move in the slotted cylinder 4. When the top shaft 36 slides to the extreme position, the paper will be pushed into the long slot 41, and then the disc-shaped shredded paper will fall into the inner cavity of the second knife shaft 21.

[0089] More specifically, when the air inlet 35 that coincides with the air outlet 33 is offset, the gas no longer enters the chute 34, and the top shaft 36 slides out of the slotted cylinder 4 under the tension of the spring and returns to the initial state. When the disc-shaped shredded paper falls into the inner cavity of the second cutter shaft 21, the second motor 43 rotates, and the rotating second motor 43 drives the auger shaft 42 to rotate. The rotating auger shaft 42 pushes the disc-shaped shredded paper to move, and the moving disc-shaped shredded paper falls from the discharge chute 44 and falls into the collection box 5.

[0090] By setting the top shaft 36, when the extrusion shaft 3 and the slotting cylinder 4 are gradually separated, the top shaft 36 is extended, so that the cut disc-shaped shredded paper can be pushed into the inner cavity of the second knife shaft 21, and then the disc-shaped shredded paper is transferred to the collection box 5 through the auger. In this process, two different types of shredded paper can be collected separately to avoid two types of shredded paper being collected in the same place. If some lawless elements want to restore the file, they need to obtain two types of shredded paper at the same time to restore it, which can further improve the confidentiality of the file.

[0091] Embodiment 3: An air groove 37 is provided in the top shaft 36, and the air groove 37 is connected to the air inlet 35;

[0092] The air groove 37 extends into the through hole 301; the side of the top shaft 36 extending into the through hole 301 is provided with evenly arranged oblique holes 38, and the oblique holes 38 are connected to the air groove 37; the oblique holes 38 are located in the through hole 301 in the initial state;

[0093] In this embodiment, the top shaft 36 is made of elastic rubber material;

[0094] In this embodiment, the inner ring surface of the slotted cylinder 4 is fixedly connected with a uniformly arranged annular layer 45;

[0095] The annular layers 45 are all inclined toward the long groove 41; the annular layers 45 are made of elastic rubber material;

[0096] Specifically, when the top shaft 36 extends into the slotting cylinder 4, the inclined hole 38 on the top shaft 36 will move out from the through hole 301. After the inclined hole 38 moves out from the through hole 301, the gas in the gas groove 37 will be ejected from the inclined hole 38. The ejected gas will continue to blow the disc-shaped shredded paper to move, so that the disc-shaped shredded paper can be blown into the inner cavity of the second blade shaft 21 to avoid blockage.

[0097] More specifically, when the top shaft 36 slides out of the slotted cylinder 4, since the top shaft 36 is made of elastic rubber material, the top shaft 36 can be deformed according to the position of the slotted cylinder 4, thereby preventing the top shaft 36 from being stuck in the slotted cylinder 4 or squeezing the slotted cylinder 4 to deform the slotted cylinder 4;

[0098] Furthermore, since the annular layer 45 is fixedly connected to the slotted cylinder 4, when the disc-shaped shredded paper is pushed into the slotted cylinder 4, the annular layer 45 can block the disc-shaped shredded paper to prevent the disc-shaped shredded paper from slipping out of the slotted cylinder 4, thereby preventing the disc-shaped shredded paper from being pushed out of the inner cavity of the second blade shaft 21.

[0099] Embodiment 4: The collection box 5 is provided with a box door, and a password lock is provided on the box door;

[0100] A second collecting bin 51 is placed in the collecting box 5 below the discharge trough 44; the second collecting bin 51 contains tap water;

[0101] In this embodiment, a third motor 52 is installed at the bottom of the second collecting bin 51; the rotating shaft of the third motor 52 extends into the interior of the second collecting bin 51;

[0102] A rotating piece 53 is installed on the rotating shaft of the third motor 52;

[0103] Specifically, after the disc-shaped shredded paper falls from the discharge chute 44, the fallen disc-shaped shredded paper will fall into the second collecting bin 51 and come into contact with the tap water in the second collecting bin 51. Then, the third motor 52 is controlled to rotate, and the rotating third motor 52 drives the rotating plate 53 to rotate, so that the disc-shaped shredded paper falling into the second collecting bin 51 can be shredded. Since the process of shredding the disc-shaped shredded paper and the process of document destruction are carried out simultaneously, the disc-shaped shredded paper can be destroyed on the spot, thereby directly destroying the possibility of some lawless elements wanting to assemble them later, thereby improving the confidentiality of the documents.

[0104] On the other hand, the present invention also provides a method for using a legal document confidentiality processing device, which is applicable to the above-mentioned legal document confidentiality processing device. The specific method of use is:

[0105] Step 1: First, start the shredder, which will control the shredding mechanism and cutting mechanism to work, and then process the documents to be destroyed;

[0106] Step 2: When the shredding mechanism is working, it will drive the cutting knives 23 evenly arranged on the two knife shafts to rotate, and the rotating cutting knives will cut the documents into block-shaped shredded paper;

[0107] Step 3: When the cutting mechanism is working, the extrusion shaft 3 and the slotted cylinder 4 will be driven to approach each other and gradually fit together. In the process of the extrusion shaft 3 and the slotted cylinder 4 fitting together, the paper can be cut into round pieces;

[0108] Step 4: After the document processing is completed, the staff turns off the shredder, then pulls out the first collection bin 12 from the machine body 1, and then cleans up the collected shredded paper.

[0109] The above shows and describes the basic principles, main features and advantages of the present invention.
