[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-3 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0022] A paper shredder suitable for financial personnel includes a cabinet 1, a waste paper box 2 is embedded in the front of the cabinet 1, a paper hopper 3 is provided through the cabinet 1, and a shredding compartment 6 is provided through the paper hopper 3 and the waste paper box 2 in the cabinet 1.

[0023] The shredder compartment 6 has a funnel-shaped internal cavity structure. A pair of first shredder discs 13 are symmetrically arranged above the funnel cavity of the shredder compartment 6, and a guide disc 14 is arranged between the outer corners of the first shredder discs 13. A pair of second shredder discs 15 are symmetrically arranged below the funnel cavity of the shredder compartment 6, and the spacing between the second shredder discs 15 is smaller than that between the first shredder discs 13. The first shredder discs 13, the guide disc 14 and the second shredder discs 15 are belt-driven and connected to a shredder motor 11.

[0024] The shredder compartment 6 is fitted with blowing windows 16 on the inner wall above the second shredder tray 15, and the blowing windows 16 are connected to air supply pipes.

[0025] The control panel 4 is embedded in the rack 1;

[0026] When using this shredder, the large-diameter paper hopper 3 allows financial personnel to easily put large quantities of paper documents into it without needing to sort the documents beforehand, simplifying the shredding operation. During the process, the braking of the shredding motor 11 drives the first shredding disc 13, the second shredding disc 15, and the guide disc 14 to rotate. After the paper falls into the shredding chamber 6 along the paper hopper 3, the paper that has passed through the first shredding disc 13 is wound into the lower end of the shredding chamber 6 by the contact between the edge of the guide disc 14 and the cut corner of the first shredding disc 13. Combined with the weight of the paper, it falls onto the second shredding disc 15, and is shredded by the second shredding disc 15. The shredded paper then falls from the bottom of the shredding chamber 6 into the waste paper box 2 for collection. When the waste paper box 2 is full, the user can pull out and separate the waste paper box 2 from the cabinet 1 to collect and dispose of the waste paper in the waste paper box 2.

[0027] Meanwhile, during the process, airflow can be blown through the air supply pipeline box blowing window 16. The airflow blowing downward along the inner wall of the shredding chamber 6, combined with the rotation of the second shredding disc 15, can clean the residual shredded paper on the second shredding disc 15 by airflow impact. This effectively avoids the situation where shredded paper accumulates on the second shredding disc 15 and affects the shredding efficiency when continuously processing large batches of paper, and improves the stability of the shredder during operation.

[0028] This paper shredder takes into account the need for financial personnel to shred large quantities of documents in their work. It uses a paper hopper 3 to facilitate the feeding of large quantities of paper into the shredder. Combined with the internal guidance and sequential setting of the coarse and fine shredding discs, it avoids paper jams when shredding large quantities of paper at the same time, while ensuring the shredding effect and improving the practicality of the paper shredder.

[0029] Furthermore, a guide bin 7 connects the paper hopper 3 and the shredder bin 6, and multiple guide rollers 9 are rolled within the guide bin 7. A guide motor 10 is belt-driven between the guide rollers 9 in the guide bin 7. Figure 2 As shown, in order to prevent a large amount of paper from clogging the opening of the shredder 6 after being fed into the paper hopper 3, the paper can be moved in the paper guide hopper 7 by the rolling of the guide roller 9. This prevents the paper from accumulating above the shredder 6 and affecting the paper entering the first shredder tray 13, thus improving the stability of the shredder when processing large amounts of paper.

[0030] Furthermore, the first shredder 13 is a blade structure with large teeth, and the surfaces of the first shredder 13 and the guide plate 14 are fitted with staggered circular cutting discs. Considering the case of a large batch entering the shredder compartment 6, the size of the paper shredding entrance can be opened by the blade structure of the first shredder 13 and the spacing between the first shredders 13, so that the paper can be rolled into the first shredder 13 and the paper can be cut into large diameters, so that the paper can be rolled into the guide plate 14 for further shredding.

[0031] Based on the above, the second shredder 15 is a staggered composite blade structure. The second shredder 15 has blades with opposite directions of the blade teeth distributed axially. The staggered blades are used to perform a second shredding process on the cut paper to ensure the shredding effect.

[0032] Furthermore, the waste paper box 2 is an open box with an opening at the top. The waste paper box 2 has a sloping feeding platform 8 at the lower end of the connection with the shredded paper bin 6. The feeding platform 8 and the waste paper box 2 form a U-shaped inner cavity on both sides. In order to prevent the shredded paper falling from the top to the bottom from accumulating in the middle of the waste paper box 2, the feeding platform 8 can guide the shredded paper falling above to the front of the waste paper box 2. The inner cavity formed on both sides of the feeding platform 8 can receive the falling shredded paper, thereby avoiding the concentrated accumulation of shredded paper and improving the utilization rate of the inner cavity of the waste paper box 2.

[0033] Furthermore, the air supply line is connected to the air supply pipe 12, and the end of the air supply pipe 12 is connected to the turbine fan assembly. The turbine fan assembly is connected to the air window 5 on the front of the cabinet 1. When braking, the turbine fan assembly is mainly opened by the control panel 4 so that the turbine fan assembly draws the outside air into the interior through the air window 5 and guides it to the air supply window 16 through the air supply pipe 12.

[0034] When using this shredder, the large-diameter paper hopper 3 allows financial personnel to easily put large quantities of paper documents into it;

[0035] During the process, the first shredder 13, the second shredder 15 and the guide plate 14 are rotated by the braking of the shredder motor 11. After the paper falls into the shredder compartment 6 along the paper hopper 3, the paper that has passed through the first shredder 13 is wound into the lower end of the shredder compartment 6 by the contact between the edge of the guide plate 14 and the cut corner of the first shredder 13. Combined with the weight of the paper, it falls onto the second shredder 15 and is shredded by the second shredder 15. The shredded paper falls from the bottom of the shredder compartment 6 into the waste paper box 2 for collection. When the waste paper box 2 is full, the user pulls out the waste paper box 2 to separate it from the cabinet 1 and discard the waste paper in the waste paper box 2.

[0036] At the same time, airflow can be blown through the air supply pipeline box blowing window 16 during the process. The airflow blows downward along the inner wall of the shredding chamber 6. Combined with the rotation of the second shredding disc 15, the airflow impacts and cleans the residual shredded paper on the second shredding disc 15. This effectively avoids the situation where shredded paper accumulates on the second shredding disc 15 and affects the shredding efficiency when continuously processing large batches of paper.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
