Description

Technical Field

[0001] The invention belongs to the technical field of destruction equipment and relates to an anti-leakage legal document destruction device and a destruction method. Background Art

[0002] Document destruction refers to the physical or digital deletion or destruction of documents that are no longer needed or must be kept confidential to ensure that the information does not fall into the hands of unauthorized persons or is improperly used. This process is very important in both business and personal life, especially when the documents contain sensitive information (such as personal information, legal documents, business secrets, etc.). Therefore, for such documents containing sensitive information, it is often necessary to use document destruction devices to shred and destroy them.

[0003] At present, commonly used document destruction devices include a shredding mechanism, which shreds paper documents into shredded paper. However, the text will still be displayed on the shredded paper, making the destruction incomplete. In order to make the destruction more thorough, a soaking mechanism is often provided inside the document destruction device to soak the shredded paper in liquid to eliminate the text on the shredded paper. For example, the publication number is CN119216044A, which is called a leakage-proof document destruction device. After the document is shredded by the shredding device, the shredded document can fall into the inside of a placement box and the text on the surface of the document can be eliminated by soaking. Another example is the publication number CN208288203U, which is called a financial document destruction device. The shredded document is soaked and shredded twice to completely destroy the document.

[0004] However, since the volume of shredded paper will increase after being soaked, and the internal space of the document destruction device is limited, frequent cleaning is required, which increases the workload. At the same time, the high water content in the shredded paper is easy to breed bacteria and mold, causing the shredded paper to produce odors and even rot, causing pollution to the surrounding environment. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides an anti-leakage legal document destruction device and destruction method, including a shell 1, a mounting block 7, two extrusion blocks 10, two air bags 27 and a horizontal moving mechanism. Two crushing teeth 6 are arranged inside the shell 1, and the mounting block 7 is arranged in the shell 1. The mounting block 7 is located below the two crushing teeth 6. A guide groove 8 is opened on the upper part of the mounting block 7. The guide groove 8 is located directly below the two crushing teeth 6, so that the shredded paper after the two crushing teeth 6 enters the guide groove 8. The guide groove 8 is a funnel-shaped structure, which is convenient for shredding paper. The liquid flows downward along the inner wall of the guide groove 8. An extrusion groove 9 is vertically opened at the lower part of the mounting block 7 near the guide groove 8. The extrusion groove 9 is connected to the guide groove 8. The cross section of the extrusion groove 9 is a rectangular structure. A U-shaped cavity 12 is opened around the extrusion groove 9 inside the mounting block 7, that is, the extrusion groove 9 is located inside the U-shaped cavity 12 and is surrounded on three sides. Two extrusion blocks 10 are relatively arranged in the extrusion groove 9. The two extrusion blocks 10 are respectively opened with an infusion cavity 35. The opposite surfaces of the two extrusion blocks 10 are respectively evenly opened with a plurality of liquid outlet holes 36, each outlet hole 36 is provided. The liquid hole 36 is connected to the corresponding infusion cavity 35, and two air bags 27 are arranged in the U-shaped cavity 12. The positions of the two air bags 27 are respectively close to the two extrusion blocks 10. Each air bag 27 is connected to the corresponding infusion cavity 35. Each air bag 27 stores water, which is convenient for squeezing each air bag 27 to squeeze and transport the water into the infusion cavity 35 and spray it out from the corresponding multiple liquid outlet holes 36. The horizontal moving mechanism has two moving ends, and the two moving ends are respectively connected to the two extrusion blocks 10. The horizontal moving mechanism is used to drive the two first extrusion rods 1 5 move toward and in the opposite direction, and squeeze the two air bags 27 in the process of moving toward each other, and drive the two squeezing blocks 10 to move toward each other through the horizontal moving mechanism to squeeze the shredded paper into shredded paper blocks, and spray a proper amount of water on the shredded paper in the process of squeezing. At the same time, squeezing and spraying water are carried out simultaneously, and the excess water is squeezed out of the shredded paper blocks in the process of squeezing, which not only reduces the volume of the shredded paper blocks, but also reduces the water content in the shredded paper blocks, thereby reducing the number of cleaning times, reducing the workload, and preventing the shredded paper from generating odor and decaying.

[0040] like Figure 2 As shown, the upper parts of the two squeezing blocks 10 are both inclined surfaces, so that the upper parts of the two squeezing blocks 10 are in an inverted figure eight shape, which makes it easy for the shredded paper to fall between the two squeezing blocks 10.

[0041] like Figure 3 , Figure 4As shown, the mechanism for moving toward each other includes two first extrusion rods 15, two second extrusion rods 16 and a bidirectional electric push rod 14. The two first extrusion rods 15 are horizontally arranged in the U-shaped cavity 12. The positions of the two first extrusion rods 15 are respectively close to the two extrusion blocks 10. One end of each first extrusion rod 15 passes through the inner wall of the U-shaped cavity 12 and is connected to the corresponding extrusion block 10. That is, the U-shaped cavity 12 is respectively provided with connecting holes 17 near the two extrusion blocks 10. Each first extrusion rod 15 passes through the corresponding connecting hole 17 and is slidably connected to the inner wall of the connecting hole 17. The interior of each first extrusion rod 15 is hollow. The interior of each first extrusion rod 15 is respectively connected to the corresponding infusion cavity 35 and the corresponding air bag 27. The two second extrusion rods 16 are respectively horizontally arranged in the U-shaped cavity 12 and are respectively close to the two first extrusion rods 15. One end of each second extrusion rod 16 is connected to the other end of the corresponding first extrusion rod 15 and is L-shaped. The two air bags 27 are located between the two second extrusion rods 16. There is a gap between the rod 16 and the corresponding airbag 27, so that the two second extrusion rods 16 can contact the two airbags 27 when moving toward each other. The two-way electric push rod 14 is horizontally arranged in the U-shaped cavity 12, and the two-way electric push rod 14 is located between the two second extrusion rods 16. The two ends of the two-way electric push rod 14 are respectively connected to the other ends of the two second extrusion rods 16. When the two-way electric push rod 14 is started, the two ends of the two-way electric push rod 14 contract, driving the two second extrusion rods 16 to move toward each other, and the two second extrusion rods 16 drive the two first extrusion rods 15 to move toward each other, and the two first extrusion rods 15 drive the two extrusion blocks 10 to move toward each other to squeeze the shredded paper therein. At the same time, the two second extrusion rods 16 contact the two airbags 27 during the process of moving toward each other, squeeze the two airbags 27, and transport the water in the two airbags 27 into the two infusion chambers 35, and spray out from the multiple liquid outlets 36 on the opposite surfaces of the two extrusion blocks 10, soak the shredded paper, and squeeze out the excess water therein during the process of squeezing the shredded paper into shredded paper blocks.

[0042] like Figure 5As shown, the inner wall of the extrusion groove 9 is horizontally provided with receiving grooves 18 near the lower position of the two extrusion blocks 10, and the two receiving grooves 18 are respectively located below the two first extrusion rods 15. Each receiving groove 18 is connected to the U-shaped cavity 12 through a horizontally arranged connecting groove 19, and the connecting groove 19 is arranged along the length direction of the receiving groove 18. A baffle 11 is horizontally arranged in each receiving groove 18, and the opposite surfaces of the two baffles 11 are located in the extrusion groove 9 and contact each other to close the lower opening of the extrusion groove 9. The lower opening of the extrusion groove 9 is closed by the two baffles 11, so that the crushed After entering the extrusion groove 9, the paper is accumulated on the two baffles 11, which is convenient for the two extrusion blocks 10 to squeeze the shredded paper. A transmission mechanism is arranged in each storage groove 18. The two transmission mechanisms are used to drive the two baffles 11 to move in the opposite direction to open the lower opening of the extrusion groove 9 when the two extrusion blocks 10 move in the opposite direction, so as to open the lower opening of the extrusion groove 9 after the extrusion is completed, so that the shredded paper blocks fall down, which is convenient for better squeezing the shredded paper into blocks and squeezing out the moisture in the shredded paper blocks, thereby further reducing the number of cleaning times and reducing the workload, and also preventing the shredded paper from generating odor and decaying.

[0043] like Figure 5 , Figure 6 As shown, the transmission mechanism includes a slider 25, a guide rod 24, a first elastic reset component and a lifting and pushing component.

The guide rod 24 is horizontally arranged between the slider 25 and the baffle 11, and the two ends of the guide rod 24 are respectively connected to the slider 25 and the baffle 11. The first elastic reset component is connected to the baffle 11, and the first elastic reset component is used to reset the baffle 11 after moving. The telescopic rod 26 is vertically arranged in the connecting groove 19, and the telescopic rod 26 is vertically arranged in the connecting groove 19. The upper end of the retractable rod 26 is connected to the lower part of the first extrusion rod 15, and the lower end of the telescopic rod 26 is located in the storage groove 18 and is located close to the side of the slider 25 away from the partition 22. The lifting and pushing assembly is connected to the telescopic rod 26. The lifting and pushing assembly is used to drive the telescopic rod 26 to pass through the slider 25 when the two first extrusion rods 15 move toward each other, and drive the slider 25 to move a certain distance when the two first extrusion rods 15 move in the opposite direction, so that the telescopic rod 26 passes through the slider 25, thereby driving the two baffles 11 to move in the opposite direction after the extrusion of the two extrusion blocks 10 is completed, and opening the lower opening of the extrusion groove 9.

[0044] like Figure 5As shown, the first elastic reset component includes a partition 22 and a first elastic member 28.

The second elastic member 29 is sleeved on the telescopic rod 26 and is located between the fixing ring 38 and the first extrusion rod 15. The two ends of the second elastic member 29 are respectively connected to the fixing ring 38 and the first extrusion rod 15, so that the fixing ring 38 can be reset after moving upward through the second elastic member 29, that is, the telescopic rod 26 can be reset after contraction. The two guide plates 34 are horizontally fixed on the inner wall of the connecting groove 19 and are located below the fixing ring 38.

The upper parts of the two guide plates 34 are respectively provided with arc-shaped protrusions 21 at the positions between the telescopic rod 26 and the slider 25, so that the two rollers 40 drive the fixing ring 38 to move upward after passing through the two arc-shaped protrusions 21, thereby driving the lower end of the telescopic rod 26 to move upward. A first inclined surface is provided at the upper part of the slider 25, and the position of the first inclined surface is close to the telescopic rod 26. A second inclined surface is provided at the upper part of the slider 25 near the partition 22.
