[0031] The utility model technical scheme proposes an automatic paper shredder.

[0032] Refer to Figures 1 to 7In this embodiment, it includes:

[0033] Body 1;

[0034] The cover 2 is rotatably connected to one end of the upper side of the machine body 1 via a rotating shaft 21 on one side, and is used to close or open the paper shredder. The inner side of the cover 2 is provided with a paper feeding port.

[0035] The paper tray assembly is inclinedly located below the machine cover 2 and is connected to the paper feeding port to guide and lift the waste paper.

[0036] The paper feeding assembly 4 is located below the machine cover 2 and is adjacent to the paper tray assembly. The paper feeding assembly 4 is used to rub the waste paper in the paper tray assembly.

[0037] The paper shredder 5 is located below the paper feeder 4. The paper shredder 5 includes a long blade shaft 51 and a short blade shaft 52. The long blade shaft 51 and the short blade shaft 52 are respectively located on the left and right sides below the paper feeder 4, and are used to work together to shred the shredded waste paper.

[0038] In this embodiment, the automatic paper shredder includes a body 1, a cover 2, a paper tray assembly, a paper feeding assembly 4, and a shredding assembly 5. The cover 2 is located on the upper end of the body 1, and one side of the cover 2 is rotatably connected to one end of the upper side of the body 1 via a rotating shaft 21, used to close or open the paper shredder. That is, the cover 2 has a closed position and an open position, and the closed position and open position can be switched by rotating the cover 2. The inner side of the cover 2 is provided with a paper feeding port. When the cover 2 is in the open position, the paper feeding port is exposed on the outer side of the upper end of the body 1, which is convenient for putting in waste paper. The paper tray assembly is inclinedly located below the cover 2, and the paper tray assembly is connected to the paper feeding port. That is, the waste paper put in through the paper feeding port is guided and lifted by the paper tray assembly. The inclined setting of the paper tray assembly is more in line with the user's habits, facilitates the stacking of paper, and reduces the friction between the paper. The paper feeding assembly... Component 4 is located below the machine cover 2, and the paper-feeding assembly 4 is positioned adjacent to the paper tray assembly. The paper-feeding assembly 4 is used to agitate the waste paper in the paper tray assembly. That is, under the action of the paper-feeding assembly 4, friction is generated on the waste paper, and the friction generated by the paper-feeding assembly 4 is greater than the friction between the papers. Therefore, the waste paper can enter the subsequent paper shredding assembly 5 for shredding under the action of the paper-feeding assembly 4. The paper shredding assembly 5 is located below the paper-feeding assembly 4. The paper shredding assembly 5 includes a long blade shaft 51 and a short blade shaft 52, and the long blade shaft 51 and the short blade shaft 52 are respectively located on the left and right sides below the paper-feeding assembly 4, and are respectively connected to a drive assembly. Under the drive of the drive assembly, they work together to shred the waste paper. Through the arrangement of the above components, the automatic shredding of waste paper is completed, the shredding efficiency is improved, and the probability of shredding multiple sheets of waste paper at the same time is reduced, preventing machine blockage.

[0039] In the embodiment, the paper holder assembly comprises a movable paper holder 31 and a fixed paper holder 32, the movable paper holder 31 is connected to the lower end of the waste paper, i.e. the movable paper holder 31 is arranged below the cover 2, one end of the movable paper holder 31 away from the waste paper is provided with a plurality of torsion springs 33, and the other end of the torsion spring 33 is connected to the fixed paper holder 32, i.e. the torsion spring 33 is used to provide support for the movable paper holder 31, as the number of paper increases or decreases, the degree of stress of the torsion spring 33 is different, i.e. the degree of stress deformation is different, so that the movable paper holder 31 can slide on the fixed paper holder 32.

[0040] In the embodiment, the body 1 is also provided with a guide paper holder 45, which is arranged between the paper rolling assembly 4 and the paper crushing assembly 5, i.e. when the paper rolling assembly 4 rolls the waste paper, the guide paper holder 45 is used to guide the waste paper, so as to facilitate the subsequent paper crushing assembly 5 to crush the waste paper, through the guide paper holder 45, the rolled waste paper is guided into the paper crushing assembly 5, improving the crushing efficiency of the waste paper.

[0041] In the embodiment, the paper rolling assembly 4 comprises a motor assembly 41, a roller 42, a long rubber roller 43 and a short rubber roller, wherein the motor assembly 41 is drivingly connected to the roller 42, i.e. under the driving of the motor assembly 41, the roller 42 rotates, the roller 42 penetrates through the long rubber roller 43 and the short rubber roller 44, driving the long rubber roller 43 and the short rubber roller 44 to rotate; the short rubber roller 44 is provided with two groups, and the two groups of short rubber rollers 44 are arranged on both sides of the long rubber roller 43, through the arrangement of the long rubber roller 43 and the short rubber roller 44, the rolling of the paper is completed; further, in the embodiment, a boss assembly is further arranged below the paper rolling assembly 4, the boss assembly comprises a first boss 61, a second boss 62 and a third boss 63, the second boss 62 and the third boss 63 are each provided with two groups, and are arranged on both sides of the first boss 61, the third boss 63 is arranged above the second boss 62, and there is an angle difference between the third boss 63 and the second boss 62, the long rubber roller 43 is tangentially arranged with the first boss 61, when the number of paper reaches six or more, the rolling assembly is easy to roll multiple paper at a time to crush, causing the machine to be blocked, the long rubber roller 43 is tangentially arranged with the first boss 61 to roll the paper to slide, and the angle difference between the second boss 62 and the third boss 63 again separates the paper, reducing the probability of rolling multiple paper at the same time, thereby avoiding the machine from being blocked.

[0042] In the embodiment, the body 1 is further provided with a paper shredding box 7, which is arranged below the paper shredding assembly 5 and used for collecting and storing the shredded paper. The paper shredding box 7 is detachably connected to the body 1, so as to facilitate cleaning of the shredded paper in the paper shredding box 7. Further, the body 1 is provided with a plurality of pulleys 8 around the lower end of the body 1. The pulleys 8 can be accommodated in the lower end of the body 1. When the automatic paper shredder needs to be moved, the pulleys 8 are moved out to slide. When the moving is completed, the pulleys 8 are accommodated in the lower end of the body 1, and the paper shredder is fixed to the ground. The body 1 is further provided with a safety flap 9, which is arranged adjacent to the cover 2. The safety flap 9 can prevent paper scraps from splashing and protect the operator. Meanwhile, the safety flap 9 is convenient for opening to maintain and overhaul the inside.
