In practice, frequent shaving leads to accelerated wear between the two, the provision of the first reinforcing ribs 18 being effective to prolong the service life of the first curved carton 4.

Embodiment two (using shredder upper cover space)

As shown in fig. 8-11, the utility model discloses an automatic kneader with crooked paper structure down is disclosed in addition, including kneader upper cover 1, kneader lower cover 2, support carton 3, the crooked carton 19 of second, kneader apron 5, nipper 6, nipper group 7, washboard group 8, paper inlet 9, arbor group 10, driving motor 11, casing and wastepaper bucket, wherein:

the upper cover 1 of the paper shredder is fixedly connected with the lower cover 2 of the paper shredder, and in this embodiment, the upper cover 1 of the paper shredder is provided with a second accommodating cavity (not shown) for accommodating the second bending paper box 19.

the second bending paper box 19 is formed by sequentially connecting a second paper box upper side wall 21, a second paper box paper blocking wall 22 and a second paper box lower side wall 23 to form a semi-open upward bending cavity, is fixedly connected to the paper shredder upper cover 1, is communicated and combined with the paper supporting box 3, and is used for accommodating stacked paper to be shredded (the situation of one piece of paper is also applicable);

The paper inlet 9 is arranged on the paper supporting box 3;

the paper twisting wheel set 8 is arranged inside the lower cover 2 of the paper shredder, is positioned on one side of the cutter shaft set 10 far away from the second bending paper box 19, and is used for rotating the paper twisting wheel set 8 under the driving of the driving motor 11 to twist the lowest paper positioned above the paper supporting box 3 and stacked with paper to be shredded to move towards the paper blocking wall 22 of the second paper box and reversely move the paper under the action of the reaction force of the paper blocking wall 22 of the second paper box so as to be bent and deformed at the paper inlet 9 and enter the paper inlet 9 downwards. In this embodiment, the number of the paper rolling wheel sets 8 is two, and the number of the paper rolling wheel sets 8 in the actual design is not limited at all, and may be three or more. In addition, the design concept of the single-side paper rubbing wheel group is that the paper rubbing structure is simplified and the economic cost is saved.

Preferably, the bottom plane of the paper tray 3 is gradually inclined upward from the end far away from the second curved paper box 19 to the end near the second curved paper box 19, so that the user can conveniently place the stacked papers to be shredded and the friction force between the stacked papers can be reduced. In actual operation, the bottom plane of the paper supporting box 3 can be horizontal, and only paper placement is not the most convenient.

Further, an included angle B between the second paper box retaining wall 22 and the bottom plane of the paper tray 3 is less than or equal to 90 degrees, as shown in fig. 8.

Further, the second bending sheet box 19 is integrally formed with the sheet holding box 3 or is formed separately therefrom.

Further, when the second bending paper box 19 and the paper supporting box 3 are made separately, the second bending paper box 19 and the paper supporting box 3 and the upper cover 1 of the paper shredder are connected through screwing, clamping, riveting or welding respectively. In practical operation, the connection mode between the upper part of the inlet of the second bending paper box 19 and the upper cover 1 of the paper shredder and between the lower part of the inlet of the second bending paper box 19 and the bottom plane of the paper supporting box 3 can be one or more of fixed connection modes such as screw connection, clamping connection, riveting or welding, and the like, and the protection range of the scheme is only required to achieve the effect of fixed connection.

Further, the sum of the lengths of the second bending sheet cassette 19 and the sheet tray 3 is equal to the sheet length of the sheet to be shredded, and the sheet length is defaulted to the length of the long side of the sheet.

Preferably, the length of the second curved sheet cassette 19 is equal to or less than one-fourth of the paper length. In this embodiment, the reason why the length of the second bending paper box 19 is not less than one half of the paper length in the first embodiment is that in this embodiment, the second bending paper box 19 is disposed in the upper cover 1 of the paper shredder, and if the scheme of "the length of the second bending paper box 19 is less than one half of the paper length" is adopted, the height of the upper cover 1 of the paper shredder is increased invisibly, and the scheme of "the length of the second bending paper box 19 is less than one fourth of the paper length" is suitable in this embodiment under the condition of balancing the reduction of the length of the paper supporting box 3 and the height of the upper cover 1 of the paper shredder, so that the length of the paper supporting box 3 can be shortened to a greater extent, the volume of the paper shredder can be effectively reduced, and the upper cover 1 of the paper shredder is not too heavy.

Preferably, the width of the entrance of the second curved sheet cassette 19 is equal to the width of the sheet support cassette 3, so that the stacked sheets to be shredded above the sheet support cassette 3 can be effectively prevented from moving left and right.
