Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] In the present utility model embodiment, please refer to Figures 1 to 3 A waste paper shredding device comprises a box body 1, a first cover plate 2 which can be opened and closed is provided on the top of the box body 1, a second cover plate 3 which can be opened and closed is provided on the bottom side wall of the box body 1, and further comprises:

[0039] A crushing mechanism, connected to the box 1, for crushing waste paper;

[0040] The inclined frame 8 is arranged at the bottom of the crushing mechanism and connected to the inner wall of the box body 1. The inclined frame 8 has a cavity inside and a plurality of through holes on the top.

[0041] A dust collecting mechanism, one end of which is connected to the box body 1 and the other end of which is connected to the inclined frame 8, is used to absorb dust generated during the crushing process;

[0042] The briquetting mechanism is connected to the box body 1 and is arranged at the bottom of the inclined frame 8, and is used for briquetting the shredded waste paper.

[0043] Pour the waste paper into the box body 1 from the top, cover it with the first cover plate 2, and the crushing mechanism crushes the waste paper. At the same time, the dust suction mechanism absorbs the dust generated during the crushing process. The crushed waste paper falls to the bottom of the box body 1. The briquetting mechanism briquettes the crushed waste paper to reduce the gap between the waste paper, thereby reducing the space occupied by the waste paper. Open the second cover plate 3 and take out the briquette waste paper.

[0044] As an embodiment of the present invention, please refer to Figures 1 to 3 , the crushing mechanism comprises:

[0045] A driving member 4 connected to the housing 1;

[0046] Crushing rollers 5, wherein the crushing rollers 5 are provided in a plurality of groups and are rotatably connected to the housing 1, and one group of the crushing rollers 5 is connected to the output end of the driving member 4;

[0047] Gears 6 are connected to the crushing rollers 5, and two adjacent sets of gears 6 are meshed with each other;

[0048] The side panels 7 are connected to the inner wall of the box body 1 and are used to prevent waste paper from falling from both sides of the box body 1 .

[0049] The driving member 4 drives a group of crushing rollers 5 to rotate, and then drives the gears 6 to rotate. Since several groups of adjacent gears 6 are meshed, the gears 6 drive other groups of gears 6 to rotate. The gears 6 drive the crushing rollers 5 to rotate, and the adjacent crushing rollers 5 rotate in opposite directions. The crushing rollers 5 crush the waste paper, and the side plates 7 prevent the waste paper from falling from the side walls of the box body 1. The driving member 4 can be a stepper motor, a servo motor, etc.

[0050] As an embodiment of the present invention, please refer to Figures 1 to 3 , the dust collection mechanism comprises:

[0051] The fan 9 is connected to the box body 1, and the output end is communicated with the inside of the inclined frame 8;

[0052] The connecting frame 10 is connected to the box body 1 and is internally communicated with the input end of the fan 9;

[0053] The filter plate 11 penetrates through the connection frame 10 and is slidably connected thereto;

[0054] One end of the connecting pipe 12 is connected to the interior of the connecting frame 10 , and the other end is connected to the interior of the top of the box body 1 .

[0055] The fan 9 sucks away the dust generated when the waste paper is crushed inside the box 1 through the connecting pipe 12, and the filter plate 11 filters the dust. The filtered clean air enters the inclined frame 8 and is blown out through the through hole to prevent the waste paper from staying on the inclined frame 8 and ensure that the waste paper can fall to the bottom of the box 1.

[0056] As an embodiment of the present invention, please refer to Figure 2 and Figure 3 , the briquetting mechanism comprises:

[0057] The telescopic member 13 has one end connected to the inclined frame 8;

[0058] A right angle plate 14 connected to the other end of the telescopic member 13;

[0059] A folding rod 15 connected to the right angle plate 14;

[0060] A longitudinal moving component, one end of which is connected to the box 1;

[0061] The inclined block 18 is connected to the other end of the longitudinal moving assembly.

[0062] Waste paper passes through the inclined frame 8 and falls to the bottom of the box body 1. The telescopic member 13 drives the right-angle plate 14 to move longitudinally. The right-angle plate 14 drives the folding rod 15 to move longitudinally. The folding rod 15 abuts against the inclined block 18, driving the inclined block 18 and the right-angle plate 14 to move downward synchronously. The bottom of the inclined block 18 and the bottom of the right-angle plate 14 are in the same horizontal plane. The inclined block 18 cooperates with the right-angle plate 14 to press the crushed waste paper. After the pressing is completed, the telescopic member 13 drives the right-angle plate 14 to move upward. At the same time, the longitudinal moving component drives the inclined block 18 to move upward and return to the original position. The telescopic member 13 can be an electric telescopic rod, a cylinder, etc.

[0063] As an embodiment of the present invention, please refer to Figure 2 and Figure 3 , the longitudinal moving component comprises:

[0064] A fixed cylinder 16 connected to the box body 1;

[0065] A sliding rod 17 is slidably connected to the fixed cylinder 16, and one end of the sliding rod 17 is connected to the inclined block 18;

[0066] The elastic member 19 is disposed inside the fixed tube 16 , and one end of the elastic member 19 is connected to the other end of the sliding rod 17 , and the other end of the elastic member 19 is connected to the fixed tube 16 .

[0067] The folding rod 15 abuts against the side of the inclined block 18, driving the inclined block 18 to move downward, and the setting of the sliding rod 17 and the fixing cylinder 16 ensures that the inclined block 18 descends stably. At the same time, the elastic member 19 undergoes elastic deformation. When the waste paper block is pressed, the telescopic member 13 drives the right-angle plate 14 and the folding rod 15 to move upward. At this time, under the reaction force of the elastic member 19, the inclined block 18 moves upward and returns to the initial position. The elastic member 19 can be a spring, a spring sheet, etc.

[0068] The working principle of the utility model is as follows: waste paper is poured into the box body 1 from the top, and the first cover plate 2 is covered. The driving member 4 drives a group of crushing rollers 5 to rotate, and then drives the gear 6 to rotate. Since several groups of adjacent gears 6 are meshed, the gears 6 of other groups are driven to rotate. The gears 6 drive the crushing rollers 5 to rotate, and the adjacent crushing rollers 5 rotate in opposite directions. The crushing rollers 5 crush the waste paper. The side plates 7 prevent the waste paper from falling from the side walls of the box body 1. The waste paper falls to the bottom of the box body 1 through the inclined frame 8. The telescopic member 13 drives the right-angle plate 14 to move longitudinally. The right-angle plate 14 drives the folding rod 15 to move longitudinally. The folding rod 15 abuts against the inclined block 18, driving the inclined block 18 and the right-angle plate 14 to move downward synchronously, and the bottom of the inclined block 18 is in the same horizontal plane as the bottom of the right-angle plate 14. The inclined block 18 cooperates with the right-angle plate 14 to press the crushed waste paper. After the pressing is completed, the telescopic member 13 drives the right-angle plate 14 to move upward. At the same time, the longitudinal moving component drives the inclined block 18 to move upward and return to the original position.
