In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] like Figures 1 to 5As shown, the present embodiment provides a shredder, which includes a chassis 1, a shredder core 3 and a roller device 4. A tilting platform 2 is provided inside the chassis 1. The table top of the tilting platform 2 is arranged at an angle with a horizontal plane. The table top of the tilting platform 2 supports the paper in an inclined posture. The tilting platform 2 is provided with a paper feeding opening 21. A limiting portion 11 is provided at the bottom of the tilting platform 2. The limiting portion 11 is used to support the bottom edge of the paper. The shredder core 3 is arranged below the paper feeding opening 21. The roller device 4 is provided with the paper feeding opening 21. When the paper is tilted and stacked on the tilting platform 2, the roller device 4 abuts against the paper at the bottom layer. The roller device 4 is used to apply friction to the paper at the bottom layer, so that the paper at the bottom layer passes through the paper feeding opening 21 and enters the shredder core 3.

[0041] Specifically, when shredding is required, the paper is tilted and stacked on the tilting platform 2. At this time, the limit portion 11 supports the bottom edge of the paper to prevent the paper from falling off the tilting platform 2, and at this time, the roller device 4 abuts against the paper at the bottom layer. When the roller device 4 rolls, the roller device 4 applies friction to the paper at the bottom layer, and the paper at the bottom layer passes through the paper inlet opening 21 and enters the shredder core 3, and is shredded by the shredder core 3. In this embodiment, the tilting platform 2 for supporting paper is tilted, and the projection area of ​​the tilting platform 2 along the vertical direction is small, so the floor space of the chassis 1 can be correspondingly reduced, ensuring that the shredder can be used in a smaller office area.

[0042] Since the tilting platform 2 supports the paper in an inclined posture and due to the gravity of the paper itself, the bottom edges of all the paper always tend to contact the limiting portion 11, and the bottom edges of all the paper are aligned at the limiting portion 11, and the user does not need to manually align the paper.

[0043] Optionally, the angle between the table top of the tilting table 2 and the horizontal plane is 25° to 75°. For example, the angle between the table top of the tilting table 2 and the horizontal plane is set to one of 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70° and 75°.

[0044] In some embodiments, the roller device 4 includes a first roller assembly 41 and a second roller assembly 42. The first roller assembly 41 and the second roller assembly 42 are arranged in parallel and at intervals. A paper feed channel is formed between the first roller assembly 41 and the second roller assembly 42. The paper feed opening 21 is aligned with the paper feed channel along a first direction, and the first direction is perpendicular to the table surface of the tilting table 2.

[0045] The rolling direction of the first roller assembly 41 is opposite to that of the second roller assembly 42 , and opposite friction forces are applied to two parts of the paper, so that the paper tends to be folded in the center and pass through the paper feeding channel.

[0046] In some other embodiments, the roller device 4 includes a group of roller components, and the group of roller components can also be used to drive the paper into the shredder core 3.

[0047] In this embodiment, the horizontal direction is the X-axis direction, the tilting direction of the tilting table 2 is the Y-axis direction, the first direction is the Z-axis direction, and the height direction of the chassis 1 is the vertical direction.

[0048] In this embodiment, the paper feeding opening 21 and the limiting portion 11 are arranged in parallel and extend in the horizontal direction, and the first roller assembly 41 and the second roller assembly 42 are arranged at intervals along the tilting direction of the tilting platform 2 .

[0049] In the existing paper shredders, the supporting platform is arranged horizontally. After the papers are stacked on the supporting platform, it is necessary to ensure that the papers are aligned in the paper feeding direction at least. Therefore, the user needs to align the papers manually, which is troublesome. If the papers are not aligned in the paper feeding direction, after the paper shredding function is started, the roller assembly may contact multiple papers at the same time. Since the thickness of the paper feed opening is fixed, multiple papers cannot fall onto the cutter at the same time, which may easily cause paper jams.

[0050] In this embodiment, the conveying direction of the paper is an inclined direction, that is, the moving direction of the upper half of the paper is inclined downward, and the moving direction of the lower half of the paper is inclined upward. Since the inclined platform 2 supports the paper in an inclined posture and the gravity of the paper itself, the bottom edges of all the papers always tend to contact the limiting portion 11, and the bottom edges of the papers are aligned at the limiting portion 11. The user does not need to manually align the papers, and the operation is simple. The roller device 4 can only apply friction to the papers at the bottom layer, and only one paper passes through the paper input opening 21 into the shredder core 3 at a time, thereby reducing the probability of paper jams.

[0051] In the first roller assembly 41 and the second roller assembly 42, the horizontal height of one is higher than the horizontal height of the other, for example, the horizontal height of the first roller assembly 41 is higher than the horizontal height of the second roller assembly 42, the first roller assembly 41 rolls the upper half of the paper downwardly toward the paper feeding opening 21 at an angle, and the second roller assembly 42 rolls the lower half of the paper upwardly toward the paper feeding opening 21 at an angle. Due to the resistance of the stapler or the adsorption force between the papers, the friction force applied by the first roller assembly 41 to the upper half of the paper and the friction force applied by the second roller assembly 42 to the lower half of the paper may be inconsistent, or the rolling speed of the first roller assembly 41 is different from the rolling speed of the second roller assembly 42. However, after overcoming the resistance of the stapler or the adsorption force between the papers, the friction force of the first roller assembly 41 and the second roller assembly 42 on the paper and the rolling speed of the rollers themselves tend to be equal.

[0052] In this embodiment, the paper feeding opening 21 and the limiting portion 11 are arranged in parallel and extend in the horizontal direction. Therefore, the bottom edge of the paper can enter the paper feeding opening 21 at the same time, avoiding the situation where one part enters first and the other part enters later.

[0053] In some other embodiments, the paper feed opening 21 extends in an inclined direction, the first roller assembly 41 and the second roller assembly 42 are spaced apart in a horizontal direction, and the rotation center line of the first roller assembly 41 and the rotation center line of the second roller assembly 42 are both set at an angle to the horizontal plane.

[0054] Optionally, a first collecting slot 22 is provided at the top edge of the tilting platform 2 , and a first step 23 is provided at one side of the first collecting slot 22 close to the paper feeding opening 21 , and the first step 23 is used for removing nails.

[0055] In some cases, the paper may be stapled with staples. In order to prevent the staplers from entering the paper feeding opening 21, in this embodiment, a first collecting slot 22 is provided on the top edge of the tilting platform 2. A first step 23 is provided on the side of the first collecting slot 22 close to the paper feeding opening 21. The end of the paper stapled with the stapler is placed on the top of the tilting platform 2. The stapler is hooked by the first step 23. When the paper at the bottom layer is subjected to friction, the position where the paper is connected to the stapler is torn. When all the paper connected to the stapler is crushed, the stapler falls into the first collecting slot 22, preventing the stapler from sliding along the table surface of the tilting platform 2 into the paper feeding opening 21.

[0056] Optionally, a second collecting slot 24 is provided in the middle of the tilting platform 2, and the second collecting slot 24 is located between the paper feeding opening 21 and the first step 23. A second step 25 is provided on one side of the second collecting slot 24 close to the paper feeding opening 21, and the second step 25 is used for removing nails.

[0057] In some emergencies, the staplers that should have fallen into the first collecting groove 22 may pass over the first step 23 and slide along the table surface of the inclined platform 2. In this embodiment, a second collecting groove 24 is provided between the paper feeding opening 21 and the first step 23 to collect the staplers and ensure that the staplers do not fall into the paper feeding opening 21. When another smaller paper needs to be shredded, if the paper also has staplers, the second step 25 is used to hook the staplers.

[0058] Optionally, a third step 26 is provided at the bottom edge of the tilting platform 2 , and the third step 26 is located between the limiting portion 11 and the paper feeding opening 21 .

[0059] When staplers are arranged at both ends of the paper, the stapler at one end of the paper is hooked by the third step 26 .

[0060] When the paper is provided with a stapler, the stapler is hooked with the step on the tilting platform 2, and can position the paper to a certain extent.

[0061] Optionally, a limit rack 13 is vertically arranged on the inner wall of the chassis 1, and the limit rack 13 is located on the side of the tilting platform 2 away from the limit portion 11. When the paper is stacked on the table top of the tilting platform 2, the top edge of the paper abuts against the limit rack 13, and the top edge of the paper is embedded in the gap between the teeth of the limit rack 13 to prevent the paper from moving at will.

[0062] Optionally, a flap 5 is rotatably installed on the top of the chassis 1, and the flap 5 is provided with an elastic paper pressing device 6 and a hook 7. The chassis 1 is also provided with a card slot 12. When the hook 7 is inserted into the card slot 12, the elastic paper pressing device 6 presses the paper against the tilting platform 2. When the thickness of the paper is reduced, the elastic paper pressing device 6 extends.

[0063] Optionally, the flap 5 is provided with a manual paper inlet 51, and when the hook 7 is inserted into the card slot 12, the manual paper inlet 51 is aligned with the paper inlet opening 21. When the paper to be shredded is reduced, the flap 5 does not need to be opened, and the paper is directly passed through the manual paper inlet 51, so that the paper directly enters the paper inlet opening 21.

[0064] Optionally, the flip cover 5 is further provided with a handle opening 52 , which is located at one side of the hook 7 . The hook 7 can be released from the engaging state in the engaging slot 12 through the handle opening 52 , so as to facilitate opening the flip cover 5 .
