DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes an intelligent shredder.

[0035] In a typical implementation of the present application, Figure 1-10 As shown, an intelligent paper shredder comprises:

[0036] A crusher 1 is used for crushing paper. The crusher 1 comprises a crushing shell 6 placed on the ground. A collecting shell 9 is slidably connected to one side of the crushing shell 6. An integrated shell 8 is fixedly connected to the inside of 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 provided on the top of the crushing cover 7.

[0037] Through the above-mentioned structure, there are two paper shredding methods. Specifically, when there is less paper, the paper can be placed inside the integrated shell 8 through the shredding opening 10 for shredding. When there is more paper, the shredding cover 7 is opened and the paper is stacked and placed inside the integrated shell 8. At the same time, the shredded paper fragments will fall into the collection shell 9 for collection.

[0038] The placing mechanism 2 is used to place paper and start the crusher 1. The placing mechanism 2 includes a top plate 13 rotatably connected to the top of the first mounting plate 25. The inside of the integrated shell 8 is rotatably connected to a twisting sleeve 17. The inside of the integrated shell 8 is rotatably connected to two driving shafts 18. The outsides of the two driving shafts 18 are fixedly sleeved with a plurality of friction sleeves 19. The twisting sleeve 17 is arranged in a cam shape. The plurality of friction sleeves 19 are arranged at intervals. The inside of the first mounting plate 25 is fixedly connected to a first limiting frame 22. The inside of the integrated shell 8 is fixedly connected to a second limiting frame 23. The inside of the second mounting plate 26 is fixedly connected to a third limiting frame 24.

[0039] The placement mechanism 2 also includes a photoelectric transmitter 11 and a photoelectric sensor 29 fixedly connected to the bottom of the crushing opening 10. The photoelectric transmitter 11 and the photoelectric sensor 29 are adapted to each other. A plurality of limit grooves 21 are provided on both sides of the inner wall of the integrated shell 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 engaged with adjacent limit grooves 21.

[0040] The top of the first mounting plate 25 is fixedly connected to the top frame 12, the top plate 13 is rotatably connected to the top of the top frame 12, the top of the top frame 12 is fixedly connected to the top spring 14, the top of the top spring 14 is fixedly connected to the bottom of the top plate 13, the inside of the integrated shell 8 is rotatably connected to the rolling shaft 16, the rolling sleeve 17 is fixedly sleeved on the outside of the rolling shaft 16, and the top of the top frame 12 is fixedly connected to the rubber block 15.

[0041] By setting the above structure, the paper can be transported. Specifically, the movable plate 20 is moved according to the width of the paper, and the movable plate 20 is stuck in the inside of the limiting groove 21. At this time, the stacked paper is placed on the top of the movable plate 20 and the top plate 13, and the cover and the crushing cover 7 are covered. At the same time, the top spring 14 lifts the top plate 13, and the top plate 13 lifts one side of the stacked paper. The top of the topmost paper is against the outside of the rubbing sleeve 17. The rubbing sleeve 17 is made of rubber and has a large friction 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 follow the movement. 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 following paper at the bottom of the top paper sticks to the top of the rubber block 15 to limit the movement of the bottom paper. The paper moved by the rubbing sleeve 17 enters the opposite side of the two friction sleeves 19, and the two driving shafts 18 rotate to drive the friction sleeve 19 to rotate. The friction sleeve 19 rotates and drives the paper to move inside the first limiting frame 22, so that the paper can enter the next process.

[0042] The destroying mechanism 3 is used to heat and cool the paper. The destroying mechanism 3 includes two heating rollers 32 rotatably connected to the inside of the integrated shell 8. The two heating rollers 32 are used to heat the paper. The inside of the integrated shell 8 is rotatably connected to two cooling rollers 36. The two cooling rollers 36 are used to cool the paper. The bottom of the first mounting plate 25 and the top of the second mounting plate 26 are both fixedly connected to two isolation plates 27. The top of the second mounting plate 26 is provided with a plurality of through holes 33.

[0043] The destruction mechanism 3 also includes two heating shells 30 fixedly connected to the inside of the integrated shell 8, and heating tubes 31 are fixedly installed inside the two heating shells 30. Two heating rollers 32 are rotatably connected to the inside of the corresponding heating shells 30. Two cooling shells 34 are fixedly connected to the inside of the integrated shell 8, and cooling tubes 35 are fixedly installed inside the two cooling shells 34. Two cooling rollers 36 are rotatably connected to the inside of adjacent cooling shells 34. One side of the inside of the integrated shell 8 is rotatably connected to a limiting plate 38. The outsides of the two heating rollers 32 and the two cooling rollers 36 are arranged in a tooth shape, and the inside of the integrated shell 8 is rotatably connected to a fan blade 28.

[0044] By setting the above-mentioned structure, the paper can be heated and cooled. Specifically, the paper is squeezed by the two heating rollers 32 during the movement and forced to continue moving. At this time, the two internal heating tubes 31 of the heating shells 30 are started to heat the two heating rollers 32 and transfer the temperature of the heating rollers 32 to the paper. At this time, the paper is heated and changes color. More specifically, the ignition point of paper is generally 233 degrees. When the paper is heated to 200 degrees, the resin and other components in the carbon powder may be carbonized or decomposed at high temperature, resulting in a change in the color of the font. At the same time, the high temperature will reduce the adhesion of the carbon powder on the surface of the paper, causing blurring and diffusion. The originally clear handwriting and images may become blurred, the edges will also spread, and the carbon powder will fall off the paper. This is because the bonding force between the carbon powder and the paper is destroyed and cannot be firmly attached to the paper, thereby 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 blade 28 rotates to blow off the toner separated from the paper. At the same time, the toner leaves an imprint on the paper during its movement, further improving the confidentiality of the document.

[0046] At this time, the paper continues to move forward and is clamped by the two cooling rollers 36. At the same time, the cooling tubes 35 inside the two cooling shells 34 are started to cool the cooling rollers 36 and transfer the temperature of the cooling rollers 36 to the paper. At this time, the paper is cooled. The drastic temperature change in a short period of 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 the tensile strength and tear strength will be reduced, making the paper easier to break during the subsequent crushing process.

[0047] The shredding mechanism 4 is used to shred the paper. The shredding mechanism 4 includes a cutting cylinder 39 rotatably connected to the inside of the integrated shell 8. A plurality of cutting protrusions 40 are fixedly connected to the outside of the cutting cylinder 39. A plurality of cutting holes 41 are opened on the outside of the cutting cylinder 39.

[0048] The pulverizing mechanism 4 also includes two speed-limiting rollers 37 rotatably connected to the inside of 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 to the inside of the integrated shell 8 , and the cutting cylinder 39 rotates on one side of the limiting plate 38 .

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

[0050] A driving mechanism 5 is provided on one side of the integrated shell 8, and 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, and the output end of the first motor 50 is fixedly connected to one end of the bottom heating roller 32, and the outside of one side of the bottom heating roller 32 and the bottom cooling roller 36 are fixedly sleeved with a fourth sprocket 51, and the outsides of the two fourth sprockets 51 are rotatably sleeved with the same fourth chain 57, and one side of the fan blade 28 is fixedly sleeved with a third gear 52, and the third gear 52 is meshed with the fourth chain 57;

[0051] A second gear 49 is fixedly sleeved on one side of the two heating rollers 32, and the two second gears 49 are meshed with each other. A third sprocket 47 is fixedly sleeved on one side of the top cooling roller 36 and the top heating roller 32, and the outer sides of the two third sprockets 47 are rotatably sleeved with the same third chain 48;

[0052] The top heating roller 32 and one side of the bottom driving shaft 18 are both fixedly sleeved with a second sprocket 45, and the outer parts of the two second sprockets 45 are rotatably sleeved with the same second chain 46. The two driving shafts 18 are both fixedly sleeved with a first gear 44, and the two first gears 44 are meshed with each other. The top driving shaft 18 and one side of the rubbing shaft 16 are both fixedly sleeved with a first sprocket 42, and the outer parts of the two first sprockets 42 are rotatably sleeved with the same first chain 43.

[0053] By setting the above structure, the paper can be driven to move. Specifically, the first motor 50 is started, and the output end of the first motor 50 rotates to drive the bottom heating roller 32 to rotate. The bottom heating roller 32 rotates to drive the second gear 49 thereon to rotate, so that the two second gears 49 mesh and rotate, driving the two heating rollers 32 to rotate in opposite directions. The top heating roller 32 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 bottom driving shaft 18 to rotate. The bottom driving shaft 18 rotates to drive the first gear 44 thereon to rotate, so that the two first gears 44 mesh and rotate, driving the two driving shafts 18 to rotate in opposite directions. The top driving shaft 18 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] At the same time, the rotation of the heating roller 32 at the bottom drives the fourth sprocket 51 thereon to rotate, the rotation of the fourth sprocket 51 drives the fourth chain 57 to rotate, and the rotation of the fourth chain 57 drives the cooling roller 36 at the bottom to rotate, so that the rotation directions of the two cooling rollers 36 are opposite, thereby conveying the paper.

[0055] A second motor 53 is fixedly installed on one side of the inner part of the crushing shell 6, and the output end of the second motor 53 is fixedly connected to one side of the cutting cylinder 39. The cutting cylinder 39 and one side of the top speed limiting roller 37 are fixedly sleeved with a fifth sprocket 54. The outer parts of the two fifth sprockets 54 are rotatably sleeved with the same fifth chain 55. One side of the two speed limiting rollers 37 are fixedly sleeved with a fourth gear 56, and the two fourth gears 56 are meshed with each other.

[0056] By setting the above-mentioned structure, the cutting drum 39 can be driven to crush the paper. Specifically, the second motor 53 is started, and the output end of the second motor 53 rotates to drive the cutting drum 39 to rotate. The cutting drum 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 top speed limiting roller 37 to rotate. The top speed limiting roller 37 rotates to drive the fourth gear 56 thereon to rotate, so that the two fourth gears 56 are engaged and rotated, driving the two speed limiting rollers 37 to rotate in opposite directions, thereby realizing the transportation and crushing of paper.

[0057] The working principle of the present invention is as follows: when it is needed, the crushing cover 7 is opened, the movable plate 20 is moved according to the width of the paper, and the movable plate 20 is stuck in the inner part of the limiting groove 21, at this time, the stacked paper is placed on the top of the movable plate 20 and the top plate 13, and the crushing cover 7 is covered, and at the same time, the top spring 14 lifts the top plate 13, and the top plate 13 lifts one side of the stacked paper, and the top of the topmost paper is against the outside of the rubbing sleeve 17, and the rubbing sleeve 17 is made of rubber material and has a large friction force on the paper. At this time, the paper can be driven to move, and the bottom paper may follow the movement during the movement of the top paper. 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 following paper at the bottom of the top paper sticks to the top of the rubber block 15, limiting the movement of the bottom paper, and the paper moved by the rubbing sleeve 17 enters the opposite side of the two friction sleeves 19, and the two driving shafts 18 rotate to drive the friction sleeve 19 to rotate, and the friction sleeve 19 rotates to drive the paper to move inside the first limiting frame 22, so that the paper can enter the next process;

[0058] During the movement of the paper, the two heating rollers 32 squeeze the paper and force it to continue to move. At this time, the heating tubes 31 inside the two heating shells 30 are started to heat the two heating rollers 32 and transfer the temperature of the heating rollers 32 to the paper. At this time, the paper is heated and changes color.

[0059] At this time, the paper continues to move forward and is clamped by the two cooling rollers 36. At the same time, the cooling pipes 35 inside the two cooling shells 34 are started to cool the cooling rollers 36 and transmit the temperature of the cooling rollers 36 to the paper. At this time, the paper cools down. After cooling, the paper may become relatively fragile, and the tensile strength and tearing strength will be reduced, making the paper easier to break in the later breaking process;

[0060] The cooling drum 36 will also drive the paper to continue moving during the process of cooling the paper. 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 continuously breaks the paper through a number of cutting protrusions 40. The paper that is not broken by the cutting protrusions 40 will be cut through the cutting holes 41, and the paper debris falls into the inside of the collection shell 9 for collection.

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