Description

Technical Field

[0001] This utility model relates to the field of office supplies, specifically to a paper shredder and a flow guide for guiding solid debris. Background Technology

[0002] Existing paper shredders mainly consist of a body, a shredding unit located at the top of the body, and a shredder drum inside the body. Paper scraps generated by the shredding unit fall directly into the shredder drum. Because the central area of ​​the shredding unit is used more frequently during operation, the accumulated scraps in the shredder drum tend to form a distribution pattern where the scraps are higher in the center and lower around the edges. When the scraps accumulate to a certain height in the center, it will trigger an alarm and stop the paper shredder. At this point, the surrounding space in the shredder drum has not been effectively utilized, resulting in insufficient scrap capacity and increasing the frequency of shredder shutdowns. Summary of the Invention

[0028] To enable those skilled in the art to better understand the solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] Example 1: As shown in the attached document Figure 1 As shown, a paper shredder includes a shredding assembly 1, a shredding cylinder 2, and a solid shredder guide 3. The shredding assembly 1 is installed above the opening of the shredding cylinder 2, and the solid shredder guide 3 is disposed at the opening of the shredding cylinder 2 and located below the shredding assembly 1.

[0030] As attached Figure 2 To be continued Figure 6 As shown, the solid debris guide 3 includes a main body 4, a pair of hooks 5, multiple left-hand guide vanes 6, and multiple right-hand guide vanes 7. The main body 4 is arranged laterally along its axis, parallel to the direction in which the paper 8 is placed in the shredder assembly 1. The two sides of the main body 4 along its axis are defined as left and right, respectively. The pair of hooks 5 are respectively located at both ends of the main body 4 for hooking onto the installation position. The main body 4 is divided into a left half and a right half from its center. The left-hand guide vanes 6 are located on both sides of the left half along its axis, forming a left-direction flow channel between adjacent left-hand guide vanes 6, with the lower end of the left-direction flow channel located to the left of the upper end of the left-direction flow channel. The right-hand guide vanes 7 are located on both sides of the right half along its axis, forming a right-direction flow channel between adjacent right-hand guide vanes 7, with the lower end of the right-direction flow channel located to the right of the upper end of the right-direction flow channel.

[0031] In this embodiment, the main body 4 includes a first main board and a second main board. The upper edges of the first main board and the second main board are connected to form a connecting shaft, while the lower edges of the first main board and the second main board are separated to form a triangular structure. Inside the triangular structure, multiple axially distributed reinforcing ribs are provided between the first main board and the second main board. Both the first main board and the second main board are curved panels. The left guide vane 6 and the right guide vane 7 are both arc-shaped panels.

[0032] The connector 5 is connected to the first main board, the second main board, and the connecting shaft via three connecting plates. The connector 5 includes a downward-opening hook, which is inverted U-shaped, and has a screw hole on its bottom surface.

[0033] As attached Figure 7 As shown, the paper shreds 8 output by the paper shredder 1 fall into the solid shredder 3, and then fall into the shredder 2 after passing through the left and right flow channels respectively. Through the path setting of the specific flow channels, the shredded paper 8 shreds are dispersed and fall into the shredder 2 more evenly, which can effectively reduce the peak height of paper shredder accumulation, so that the shredder 2 can hold more paper shredder before alarming and stopping.

[0034] As attached Figure 8 As shown, the solid debris guide 3 is mounted on the edge of the shredder 2 via the hanger 5. After the solid debris guide 3 is installed on the shredder 2, the paper shredder can then operate and process the paper 8 after the paper shredder assembly 1 is installed.

[0035] The experiment verified the following: (see attached) Figure 9 As shown, when the number of shredded sheets reaches 20, significant debris accumulation occurs in the middle of the shredder without the guide 3. However, in the shredder using the solid debris guide 3 in this application, the paper debris is distributed more evenly in the shredder cylinder 2. (See attached...) Figure 10 As shown, when the number of shredded sheets reaches 80, the paper scraps accumulated in the middle of the shredder without the guide 3 are close to the opening of the shredder cylinder 2. However, in the shredder using the solid shredder guide 3, the paper scraps accumulate more evenly in the middle of the shredder cylinder 2. (See attached diagram) Figure 11 As shown, when the number of shredded sheets 8 reaches 130, the shredder without the deflector 3 has already triggered an alarm and stopped working due to excessive shred peak, while the shredder with the solid shred deflector 3 can continue to work. The shredder with the solid shred deflector 3 will only trigger an alarm and stop working when the number of shredded sheets 8 reaches 190, which means that the shredder's shredder cylinder 2 can hold about 40% more shreds than the shredder without the deflector 3.
