Description

Technical Field

[0001] The present invention relates to the technical field of paper shredding, and specifically to an intelligent paper shredder. Background Art

[0002] A paper shredder is an office device used to cut paper into small pieces. The paper shredder can shred documents containing sensitive information to prevent information leakage, protect the privacy and security of individuals and companies. The volume of the shredded paper is greatly reduced, which is convenient for storage and processing, helps save office space. At the same time, the shredded paper is easier to recycle, which is conducive to the recycling of resources and meets environmental protection requirements. By processing waste paper with a paper shredder, the amount of garbage generated in the office can be effectively reduced, and the garbage disposal cost can be reduced.

Specific implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0034] As introduced in the background technology, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an intelligent paper shredder.

[0035] In a typical implementation mode of the present application, as Figure 1-10 shown, an intelligent paper shredder includes

[0036] A crusher 1, the crusher 1 is used to crush paper. The crusher 1 includes a crushing shell 6 placed on the ground. A collection shell 9 is slidably connected to one side of the crushing shell 6. An integrated shell 8 is fixedly connected inside the crushing shell 6. A first mounting plate 25 and a second mounting plate 26 are fixedly installed inside the integrated shell 8. A crushing cover 7 is rotatably hinged to the top of the crushing shell 6. A crushing opening 10 is opened at the top of the crushing cover 7;

[0037] With the above-described structure provided, there are two paper shredding methods. Specifically, when there is a small amount of paper, the paper can be placed inside the integrated housing 8 through the shredding opening 10 for shredding. When there is a large amount of paper, the shredding cover 7 is opened, and the paper is stacked and placed inside the integrated housing 8. At the same time, the shredded paper debris will fall into the collection housing 9 for collection.

[0038] The placing mechanism 2 is used to place the paper and start the paper shredder 1. The placing mechanism 2 includes a top plate 13 rotatably connected to the top of the first mounting plate 25. A rubbing sleeve 17 is rotatably connected inside the integrated housing 8. Two drive shafts 18 are rotatably connected inside the integrated housing 8. A number of friction sleeves 19 are fixedly sleeved on the outer parts of the two drive shafts 18. The rubbing sleeve 17 is arranged in a cam shape, and a number of friction sleeves 19 are arranged at intervals. A first limiting frame 22 is fixedly connected inside the first mounting plate 25. A second limiting frame 23 is fixedly connected inside the integrated housing 8. A third limiting frame 24 is fixedly connected inside the second mounting plate 26.

[0039] The placing mechanism 2 further includes a photoelectric emitter 11 and a photoelectric inductor 29 fixedly connected to the bottom of the shredding opening 10. The photoelectric emitter 11 and the photoelectric inductor 29 are adapted to each other. A number of limiting grooves 21 are opened on both sides of the inner wall of the integrated housing 8. A moving plate 20 is slidably connected to the top of the first mounting plate 25. Both sides of the moving plate 20 are clamped with the adjacent limiting grooves 21.

[0040] A top frame 12 is fixedly connected to the top of the first mounting plate 25. The top plate 13 is rotatably connected to the top of the top frame 12. A top spring 14 is fixedly connected to the top of the top frame 12. The top of the top spring 14 is fixedly connected to the bottom of the top plate 13. A rubbing shaft 16 is rotatably connected inside the integrated housing 8. The rubbing sleeve 17 is fixedly sleeved on the outer part of the rubbing shaft 16. A rubber block 15 is fixedly connected to the top of the top frame 12.

[0041] Through the above - set structure, the paper can be conveyed. Specifically, the moving plate 20 is moved according to the width of the paper and is stuck inside the limiting groove 21. At this time, the stacked paper is placed on the top of the moving plate 20 and the top plate 13, and the crushing cover 7 is covered. At the same time, the top spring 14 jacks up the top plate 13, and the top plate 13 jacks up one side of the stacked paper. The top of the top - most paper abuts against the outside of the rubbing sleeve 17. The rubbing sleeve 17 is made of rubber and has a large frictional force on the paper. At this time, the paper can be driven to move. During the movement of the top paper, the bottom paper may move along. At this time, the rubbing shaft 16 rotates and drives the rubbing sleeve 17 to rotate. During the rotation of the rubbing sleeve 17, the paper following the movement at the bottom of the top paper adheres to the top of the rubber block 15, restricting the movement of the bottom paper. The paper driven by the rubbing sleeve 17 enters the relative side of the two friction sleeves 19. The two driving shafts 18 rotate to drive the friction sleeves 19 to rotate, and the friction sleeves 19 rotate to drive the paper to move inside the first limiting frame 22, enabling the paper to enter the next process.

[0042] The destruction mechanism 3 is used to heat up and cool down the paper. The destruction mechanism 3 includes two heating drums 32 rotatably connected inside the integrated shell 8. The two heating drums 32 are used to heat up the paper. Two cooling drums 36 are rotatably connected inside the integrated shell 8. The two cooling drums 36 are used to cool down the paper. Two heat - insulating plates 27 are fixedly connected to the bottom of the first mounting plate 25 and the top of the second mounting plate 26 respectively. A number of through - holes 33 are opened at the top of the second mounting plate 26;

[0043] The destruction mechanism 3 further includes two heating shells 30 fixedly connected inside the integrated shell 8. Heating tubes 31 are fixedly installed inside the two heating shells 30 respectively. The two heating drums 32 are respectively rotatably connected inside the corresponding heating shells 30. Two cooling shells 34 are fixedly connected inside the integrated shell 8. Cooling tubes 35 are fixedly installed inside the two cooling shells 34 respectively. The two cooling drums 36 are respectively rotatably connected inside the adjacent cooling shells 34. A limiting plate 38 is rotatably connected to one side inside the integrated shell 8. The outer sides of the two heating drums 32 and the two cooling drums 36 are arranged in a toothed shape. A fan blade 28 is rotatably connected inside the integrated shell 8.

[0044] Through the above - set structure, the paper can be heated and cooled. Specifically, during the movement of the paper, it is squeezed by two heating drums 32 and forced to continue moving. At this time, the heating tubes 31 inside the two heating shells 30 are started to heat the two heating drums 32, and the temperature of the heating drums 32 is conducted to the paper. At this time, the paper is heated and undergoes a color change. More specifically, the ignition point of the paper is generally 233 degrees, and when the paper is heated to 200 degrees, components such as resin in the toner may undergo carbonization or decomposition at high temperatures, resulting in a change in the font color. At the same time, the high temperature will reduce the adhesion of the toner on the paper surface, resulting in blurring and spreading. The original clear handwriting and images may become blurred, and the edges will also spread, and the toner will fall off the paper. This is because the binding force between the toner and the paper is damaged and cannot be firmly attached to the paper, thus achieving the effect of document confidentiality;

[0045] The heated paper continues to move forward through the second limiting frame 23. During the movement, the fan blades 28 rotate to blow off the toner separated from the paper. At the same time, during the movement of the toner, it imprints on the paper, further improving the document confidentiality effect;

[0046] At this time, the paper continues to move forward and is clamped by two cooling drums 36. At the same time, the cooling tubes 35 inside the two cooling shells 34 are started to cool the cooling drums 36, and the temperature of the cooling drums 36 is conducted to the paper. At this time, the paper is cooled. The drastic temperature change in a short time will have a certain impact on the strength of the paper. Heating will cause a certain degree of change in the fiber structure of the paper. After cooling, the paper will become relatively fragile, and both the tensile strength and the tear strength will decrease, making the paper easier to break during the later crushing process.

[0047] The crushing mechanism 4 is used to crush the paper. The crushing mechanism 4 includes a cutting cylinder 39 rotatably connected inside the integrated shell 8. A number of cutting tabs 40 are fixedly connected to the outside of the cutting cylinder 39, and a number of cutting holes 41 are opened on the outside of the cutting cylinder 39;

[0048] The crushing mechanism 4 further includes two speed - limiting rollers 37 rotatably connected inside the integrated shell 8. The outside of the two speed - limiting rollers 37 is arranged in a toothed shape. A limiting plate 38 is fixedly connected inside the integrated shell 8, and the cutting cylinder 39 rotates on one side of the limiting plate 38.

[0049] Through the above-mentioned structure set, the paper can be broken. Specifically, during the process of cooling the paper by the cooling roller 36, the paper will also be driven to continue moving. At this time, the two speed-limiting rollers 37 clamp the paper and drive the paper to move. The paper enters the inside of the limiting plate 38, which restricts the paper from moving up and down. At this time, the cutting cylinder 39 rotates, and the paper is continuously broken by a number of cutting tabs 40. The paper that is not broken by the cutting tabs 40 will be cut through the cutting holes 41, and the paper debris will fall into the inside of the collection shell 9 for collection.

[0050] A driving mechanism 5 is provided on one side of the integrated shell 8. The driving mechanism 5 is used to drive the paper inside the crusher 1 to move. The driving mechanism 5 includes a first motor 50 fixedly installed on one side of the inner wall of the crushing shell 6. The output end of the first motor 50 is fixedly connected to one end of the bottom heating roller 32. Both the outer sides of one side of the bottom heating roller 32 and the bottom cooling roller 36 are fixedly sleeved with fourth sprockets 51. The same fourth chain 57 is rotatably sleeved outside the two fourth sprockets 51. A third gear 52 is fixedly sleeved on one side of the fan blade 28, and the third gear 52 meshes with the fourth chain 57.

[0051] Both sides of the two heating rollers 32 are fixedly sleeved with second gears 49, and the two second gears 49 mesh with each other. Both the outer sides of one side of the top cooling roller 36 and the top heating roller 32 are fixedly sleeved with third sprockets 47. The same third chain 48 is rotatably sleeved outside the two third sprockets 47.

[0052] Both sides of the top heating roller 32 and one side of the bottom drive shaft 18 are fixedly sleeved with second sprockets 45. The same second chain 46 is rotatably sleeved outside the two second sprockets 45. Both sides of the two drive shafts 18 are fixedly sleeved with first gears 44, and the two first gears 44 mesh with each other. Both the outer sides of one side of the top drive shaft 18 and the rubbing shaft 16 are fixedly sleeved with first sprockets 42. The same first chain 43 is rotatably sleeved outside the two first sprockets 42.

[0053] With the above - set structure, the paper can be driven to move. Specifically, start the first motor 50. The output end of the first motor 50 rotates to drive the heating drum 32 at the bottom to rotate. The heating drum 32 at the bottom rotates to drive the second gear 49 thereon to rotate, causing the two second gears 49 to mesh and rotate, driving the two heating drums 32 to rotate in opposite directions. The heating drum 32 at the top rotates to drive the second sprocket 45 thereon to rotate. The second sprocket 45 rotates to drive the second chain 46 to rotate. The second chain 46 rotates to drive the drive shaft 18 at the bottom to rotate. The drive shaft 18 at the bottom rotates to drive the first gear 44 thereon to rotate, causing the two first gears 44 to mesh and rotate, driving the two drive shafts 18 to rotate in opposite directions. The drive shaft 18 at the top rotates to drive the first sprocket 42 thereon to rotate. The first sprocket 42 rotates to drive the first chain 43 to rotate. The first chain 43 rotates to drive the rubbing shaft 16 to rotate;

[0054] Meanwhile, the heating drum 32 at the bottom rotates to drive the fourth sprocket 51 thereon to rotate. The fourth sprocket 51 rotates to drive the fourth chain 57 to rotate. The fourth chain 57 rotates to drive the cooling drum 36 at the bottom to rotate, making the rotation directions of the two cooling drums 36 opposite, thereby conveying the paper.

[0055] On one side inside the crushing shell 6, a second motor 53 is fixedly installed. The output end of the second motor 53 is fixedly connected to one side of the cutting cylinder 39. Both the cutting cylinder 39 and one side of the speed - limiting roller 37 at the top are fixedly sleeved with a fifth sprocket 54. The two fifth sprockets 54 are rotatably sleeved outside with the same fifth chain 55. On one side of both the speed - limiting rollers 37, a fourth gear 56 is fixedly sleeved. The two fourth gears 56 mesh with each other.

[0056] With the above - set structure, the cutting cylinder 39 can be driven to crush the paper. Specifically, start the second motor 53. The output end of the second motor 53 rotates to drive the cutting cylinder 39 to rotate. The cutting cylinder 39 rotates to drive the fifth sprocket 54 thereon to rotate. The fifth sprocket 54 rotates to drive the fifth chain 55 to rotate. The fifth chain 55 rotates to drive the speed - limiting roller 37 at the top to rotate. The speed - limiting roller 37 at the top rotates to drive the fourth gear 56 thereon to rotate, causing the two fourth gears 56 to mesh and rotate, driving the two speed - limiting rollers 37 to rotate in opposite directions, realizing the conveying and crushing of the paper.

[0057] Working principle of the present invention: When in use, open the crushing cover 7, move the moving plate 20 according to the width of the paper, and clamp the moving plate 20 inside the limiting groove 21. At this time, place the stacked papers on the top of the moving plate 20 and the top plate 13, cover the crushing cover 7, and at the same time, the top spring 14 pushes up the top plate 13, and the top plate 13 pushes up one side of the stacked papers. The top of the topmost paper abuts against the outside of the rubbing sleeve 17. The rubbing sleeve 17 is made of rubber and has a large frictional force on the paper. At this time, the paper can be driven to move. During the movement of the top paper, the bottom paper may move along. At this time, the rubbing shaft 16 rotates and drives the rubbing sleeve 17 to rotate. During the rotation of the rubbing sleeve 17, the paper following the movement at the bottom of the top paper adheres to the top of the rubber block 15, restricting the movement of the bottom paper. The paper moved by the rubbing sleeve 17 enters the opposite side of the two friction sleeves 19. The two drive shafts 18 rotate to drive the friction sleeves 19 to rotate, and the friction sleeves 19 rotate to drive the paper to move inside the first limiting frame 22, enabling the paper to enter the next process;

[0058] During the movement of the paper, it is squeezed by the two heating rollers 32 and forced to continue moving. At this time, start the heating tubes 31 inside the two heating shells 30 to heat up the two heating rollers 32, and conduct the temperature of the heating rollers 32 to the paper. At this time, the paper is heated and undergoes a color change;

[0059] At this time, the paper continues to move forward and is clamped by the two cooling rollers 36. At the same time, start the cooling tubes 35 inside the two cooling shells 34 to cool the cooling rollers 36, and conduct the temperature of the cooling rollers 36 to the paper. At this time, the paper is cooled. After cooling, the paper may become relatively fragile, and both the tensile strength and the tear strength will decrease, making the paper easier to break during the subsequent crushing process;

[0060] During the process of cooling the paper by the cooling rollers 36, the paper is also driven to continue moving. At this time, the two speed-limiting rollers 37 clamp the paper and drive it to move. The paper enters the inside of the limiting plate 38, restricting the paper from moving up and down. At this time, the cutting cylinder 39 rotates, and the paper is continuously crushed by a number of cutting tabs 40. The paper that is not crushed by the cutting tabs 40 will be cut through the cutting holes 41, and the paper scraps fall into the inside of the collection shell 9 for collection.

[0061] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
