Description

Technical Field

[0001] The present invention relates to the technical field of paper shredders, and in particular to an intelligent automatic paper feeding mechanism and a paper shredder thereof. Background Art

[0002] A shredder consists of a set of rotating blades, a paper comb, and a drive motor. Paper is fed between the interlocking blades, where it is cut into numerous tiny pieces to maintain confidentiality. The shredder's shredding method refers to the shape of the paper after it is shredded by the shredder's blades. Depending on the blade's configuration, existing shredding methods include: shredded, granular, segmented, foamed, striped, and shredded.

[0003] A search revealed a utility model with publication number CN202860650U, which relates to an automatic paper feed mechanism for a shredder. The mechanism comprises two V-shaped paper feed mechanisms, each with its own opposing surfaces. The opposing surfaces of the two feed mechanisms function as friction surfaces, which move relative to each other and fold the paper in half. A guide opening is provided between the two feed mechanisms, allowing the folded paper to pass through and enter the blade engagement area. The pressure device is positioned above the guide opening and presses the paper placed on the paper feed mechanism against the friction surface. During the actual shredding process, the shredder simply stacks the paper to be shredded neatly on the paper feed mechanism and uses the pressure device to press the paper against the friction surface. This reduces labor costs and significantly reduces operator time. The utility model also discloses a shredder equipped with this automatic paper feed mechanism.

[0004] Although the automatic paper feeding mechanism can automatically feed paper, it still has the following defects when in use:

[0005] 1. There is still the problem of incomplete shredding when cutting paper. Paper can only be cut into long strips, which still poses the risk of information leakage.

[0006] 2. Manual paper feeding has a greater risk, the amount of automatic paper feeding is low, it cannot be adjusted according to the amount of paper, and the shredding efficiency is low.

[0007] In view of the above problems, the present invention document proposes an intelligent automatic paper feeding mechanism and a paper shredder thereof. Summary of the Invention

[0057] However, as is well known to those skilled in the art, the working principle and wiring method of the servo motor 30 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0058] The working principle and usage process of this technical solution are as follows:

[0059] When in use, the paper to be shredded is placed on the placement plate 22, and the hand wheel 10 is rotated. The hand wheel 10 drives the screw 11 to rotate, and the screw 11 drives the sliding plate 14 to move vertically downward.

The vertical plate 21 drives the second horizontal plate 24 to move vertically downward, and the tension spring 25 is stretched;

[0060] After the paper is placed, the paper feeding box 13 can be pressed vertically downward. At this time, the paper feeding box 13 drives the two first transverse plates 12 to move vertically downward. The first transverse plates 12 squeeze the first spring 9, and the paper feeding box 13 drives the paper into the interior of the shredder housing 1. At the same time, the second rack 23 at the bottom of the placing plate 22 is engaged with the second spur gear 38, so that a large number of papers can be shredded at the same time. The height of the sliding plate 14 can also be adjusted according to the amount of paper to ensure the movement of the paper.

[0061] At this time, the servo motor 30 is started, and the output shaft of the servo motor 30 drives the worm 32 to rotate, and the worm 32 drives the third shaft 8 to rotate. The third shaft 8 can drive the first shaft 3 and the second shaft 4 to rotate through the transmission of the synchronous wheel 5 and the synchronous belt 7. The first shaft 3 drives the second spur gear 38 to rotate, which in turn drives the second rack 23 to move horizontally. The second rack 23 drives the placement plate 22 and the vertical plate 21 to move horizontally. The vertical plate 21 pushes the paper to the other side of the multiple third shredding blades 34. At this time, the paper is cut horizontally. The paper is cut when passing through the third shredding blades 34;

[0062] The second rotating shaft 4 that rotates simultaneously can drive the other two second rotating shafts 4 to rotate synchronously under the transmission of the first spur gear 6. The second rotating shaft 4 drives the second shredding blade 33 to rotate. The second shredding blade 33 shreds and mixes the paper. At the same time, the worm 32 drives the worm gear 29 to rotate. The worm gear 29 drives the fourth rotating shaft 28 to rotate. The fourth rotating shaft 28 drives the half gear 27 to rotate. The half gear 27 drives the two first racks 16 to move laterally at intervals. The first rack 16 drives the slider 15 to move laterally and squeeze the second spring 26. The slider 15 drives the first mounting plate 19 to move laterally. The first mounting plate 19 drives the first shredding blade 20 to move laterally.
