[0003] Since a space is needed to place the paper to be shredded, the existing automatic paper shredder mainly adopts a mode of setting a paper placing platform in the paper shredder housing to place the paper to be shredded. However, since the paper placing platform needs to be set in the housing, the paper shredder body is too large, the use area is too large, which is not conducive to miniaturization, and it is difficult to place the paper to be shredded when the paper to be shredded is large, which is inconvenient to use and has high production cost. In addition, during the paper feeding process, the staple is easily dragged into the paper shredder core, which affects the service life of the paper shredder core.

[0004] Therefore, it is urgent to study a paper containing mechanism to solve the problem that the existing paper placing platform occupies a large area and easily drags the staple into the paper shredder core, thereby affecting the service life of the paper shredder core. SUMMARY

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Example 1

[0046] like Figures 1-8 As shown, this embodiment provides a paper holding mechanism, which includes a housing 1, a paper feeding assembly 2, and a first paper-pressing component 3. The housing 1 has a placement cavity 11, which includes a conveying section 111 and a placement section 112 that are connected to each other. The conveying section 111 and the placement section 112 are arranged at an angle. The housing 1 has a first paper inlet 12 at the conveying section 111, which is connected to the conveying section 111. The paper feeding assembly 2 is located in the housing 1 and is positioned on one side of the first paper inlet 12. The first paper-pressing component 3 is located in the housing 1. The width of the placement section 112 at the first paper-pressing component 3 is variable. Specifically, the first paper-pressing component 3 can move between a first position and a second position. When the first paper-pressing component 3 is in the first position, the distance between it and the first sidewall 1121 of the receiving section 112 away from the first paper inlet 12 is L1. When the first paper-pressing component 3 is in the second position, the distance between it and the first sidewall 1121 is L2, where L2 > L1. The bottom surface of the conveying section 111 is a paper-placing platform 1111, and the first paper inlet 12 is located on the paper-placing platform 1111. L1 ≥ 1 mm; this value setting allows a small amount of paper to be placed when the first paper-pressing component 3 is in the first position.

[0047] The paper containing mechanism is provided with the conveying section 111 and the placing section 112 arranged at an angle, so that the paper 100 can be bent, and the occupied area of the paper containing mechanism is effectively reduced. In addition, the first paper pressing part 3 is arranged, so that the stacked paper 100 is clamped between the first side wall 1121 and the first paper pressing part 3. When the paper feeding assembly 2 drags the paper 100 into the first paper feeding port 12, one end of the paper 100 with the staple is bent and stopped by the first paper pressing part 3. At this time, under the further dragging of the paper feeding assembly 2, the lowermost paper 100 is separated from the staple and is dragged into the first paper feeding port 12 alone, so as to avoid the staple entering the shredder core 6 and improve the service life of the shredder core 6.

[0048] The width of the placing section 112 at the first paper pressing part 3 is variable and can change with the thickness of the paper 100, so as to ensure that the paper 100 is always pressed tightly and adheres to the first paper pressing part 3, and the first paper pressing part 3 always has a stopping effect.

[0049] The first paper pressing part 3 is in the form of a plate, the first end of the first paper pressing part 3 is rotatably arranged in the shell 1, and the second end of the first paper pressing part 3 can be close to or away from the first side wall 1121, and the minimum distance between the second end of the first paper pressing part 3 and the first side wall 1121 is L1. The minimum distance L1 is 1 mm.

[0050] In the embodiment, the first paper pressing part 3 comprises a connecting plate 301 and a staple plate 302 connected with each other, the connecting plate 301 and the staple plate 302 are arranged at an angle, the connecting plate 301 is rotatably connected to the shell 1, and the staple plate 302 faces the bottom of the placing section 112. The minimum distance between the staple plate 302 and the first side wall 1121 is L1. Preferably, when the distance between the staple plate 302 and the first side wall 1121 is the smallest, i.e. when the first paper pressing part 3 is in the first position, the staple plate 302 is vertically downward. This arrangement makes the contact area between the staple plate 302 and the paper 100 as large as possible, avoids the paper 100 being pulled apart during the dragging process, and makes the paper 100 tear at the staple, so as to separate the paper 100 from the staple as much as possible. In addition, the above structure increases the strength of the first paper pressing part 3.

[0051] Regarding the driving mode of the first paper pressing part 3, in the embodiment, the paper containing mechanism comprises a first elastic member 31 arranged between the first paper pressing part 3 and the shell 1, for moving the second end close to the first side wall 1121. In an embodiment, the first elastic member 31 is a compression spring, one end of the compression spring abuts against the shell 1, and the other end abuts against the first paper pressing part 3. In another embodiment, the first elastic member 31 can be a torsion spring, one end of the torsion spring abuts against the shell 1, and the other end abuts against the staple plate. The shell 1 is provided with two rotating holes, and the two ends of the first paper pressing part 3 are respectively provided with a rotating pin, and the two rotating pins are respectively rotatably connected with the two rotating holes.

[0052] In other embodiments, the first pressing paper 3 can be slidingly arranged in the casing 1. Specifically, the casing 1 is provided with a sliding groove, and the first pressing paper 3 is slidingly arranged in the sliding groove. Preferably, the sliding groove is arranged to be inclined, and is inclined downward in a direction away from the conveying section 111. In this embodiment, a resilient member can also be arranged to exert a resilient force on the first pressing paper 3, so that the first pressing paper 3 is close to the first side wall 1121. Further, an end of the first pressing paper 3 close to the first side wall 1121 is provided with a downwardly bent stopper plate. This arrangement makes the bent paper 100 contact the stopper plate, so that the first pressing paper 3 and the upper side wall of the sliding groove are in abutment and pressed tightly, and the frictional force generated prevents the first pressing paper 3 from retracting, i.e., the frictional force generated prevents the first pressing paper 3 from moving away from the first side wall 1121.

[0053] To improve the success rate of removing the staple, in this embodiment, the paper containing mechanism includes a tacking member 4, one end of the tacking member 4 is fixedly arranged in the casing 1, and the other end of the tacking member 4 is directed toward the bottom of the placing section 112, and the other end of the tacking member 4 is located above the tacking plate 302. The tacking member 4 is located in the placing section 112. The tacking member 4 and the casing 1 are integrally formed. In this embodiment, the tacking member 4 is an arc-shaped plate structure, which is bent downward from a direction away from the first paper inlet 12, and the tangent line of the other end of the tacking member 4 extends in a vertical direction.

[0054] To further improve the success rate of removing the staple, the casing 1 is provided with a first tacking portion 14, which is located above the tacking member 4 and on the side of the first paper inlet 12 close to the placing section 112. The first tacking portion 14 is a stepped structure for stopping the staple below the paper 100. The first tacking portion 14 includes a first tacking surface 141, which is perpendicular to the bottom surface of the conveying section 111, i.e., the first tacking surface 141 is perpendicular to the paper placing platform 1111. When the paper 100 passes through the first tacking surface 141, the staple is stopped by the first tacking surface 141. Of course, in other embodiments, the first tacking surface 141 can be arranged to be inclined, and is close to the first paper inlet 12 from top to bottom. The three-stage tacking mechanism greatly improves the reliability of tacking.

[0055] In this embodiment, the included angle between the conveying section 111 and the placing section 112 is α, and 70°≥α≥135°. Preferably, α=90°.

[0056] Optionally, the second tacking portion 15 of the casing 1 is located at the side of the first paper feeding port 12 away from the placement section 112, and is a stepped structure located in the conveying section 111. The second tacking portion 15 includes a second tacking surface 151, which is perpendicular to the bottom surface of the conveying section 111, i.e. perpendicular to the paper placement platform 1111. When the paper sheet 100 passes the second tacking surface 151, the staple needle is stopped by the second tacking surface 151. Of course, in other embodiments, the second tacking surface 151 can be inclinedly arranged from top to bottom close to the first paper feeding port 12.

[0057] Regarding the structure of the paper feeding assembly 2, in the embodiment, the paper feeding assembly 2 includes a first paper feeding roller 21 and a second paper feeding roller 22, which are oppositely arranged and separately located at the two sides of the first paper feeding port 12. This arrangement can drag the paper sheet 100 on both sides of the first paper feeding port 12 into the first paper feeding port 12, thereby improving the shredding efficiency of the paper sheet 100. The first paper feeding roller 21 and the second paper feeding roller 22 are both rubber rollers.

[0058] The first paper feeding roller 21 and the second paper feeding roller 22 are both provided with a plurality of rollers, which are oppositely arranged. Specifically, the first paper feeding roller 21 and the second paper feeding roller 22 are both provided with four rollers. The first shaft 23 and the second shaft 24 are oppositely arranged and connected through gear transmission. The first paper feeding roller 21 is fixed to the first shaft 23, and the second paper feeding roller 22 is fixed to the second shaft 24. The first shaft 23 is connected to the power member 25 through gear transmission.

[0059] The casing 1 includes a base 101 and a cover 102. The cover 102 can be arranged on the base 101, and a placement cavity 11 is formed between the cover 102 and the base 101. The cover 102 is connected to the paper pressing plate 103 through the second elastic member 104 at the conveying section 111. This arrangement ensures that the paper sheet 100 is always pressed, which is conducive to the dragging of the paper feeding assembly 2.

[0060] Optionally, the cover 102 is provided with a second paper feeding port 13 located directly above the first paper feeding port 12, through which the paper sheet 100 can pass. This arrangement allows manual paper feeding. The paper sheet 100 enters the shredder core 6 through the second paper feeding port 13 and the first paper feeding port 12. In the embodiment, the paper pressing plate 103 is provided with two paper pressing plates 103, which are separately located at the two sides of the second paper feeding port 13.

[0061] Embodiment Two

[0062] In combination Figures 9-10As shown, the paper containing mechanism of the embodiment also includes a second paper pressing member 5, one end of which is rotatably arranged in the casing 1, and the other end of which is capable of moving close to or away from the first paper pressing member 3. Specifically, the other end of the second paper pressing member 5 is capable of moving between a third position and a fourth position, the distance between the first paper pressing member 3 and the other end of the second paper pressing member 5 is L3 when the other end of the second paper pressing member 5 is located at the third position, and the distance between the first paper pressing member 3 and the other end of the second paper pressing member 5 is L4 when the other end of the second paper pressing member 5 is located at the fourth position, and L4 is greater than L3. Here, L3 is greater than 1mm, so as to facilitate the placement of a small amount of paper. Here, a third elastic member 51 is arranged between the second paper pressing member 5 and the casing 1, for moving the other end of the second paper pressing member 5 close to the first paper pressing member 3, i.e. for stopping the other end of the second paper pressing member 5 at the third position. Preferably, one end of the second paper pressing member 5 is rotatably arranged in the casing 1, and the other end of the second paper pressing member 5 is provided with a flange structure, and when the other end of the second paper pressing member 5 is located at the third position, the flange is vertically downward, so as to expand the contact area with the paper as much as possible; in addition, the flange can also improve the strength of the second paper pressing member 5.
