[0050] As a preferred scheme of the present application, the moving partition assembly comprises a second lead screw 15, a first plate 21, a second plate 22, a third plate 23, a second motor 27, two moving blocks 26 and a second telescopic assembly, the outer wall of the second motor 27 is fixedly connected with the upper end of the inner wall of the waste paper box 12, the output shaft of the second motor 27 is fixedly connected with one end of the second lead screw 15, the other end of the second lead screw 15 penetrates through the two moving blocks 26 and is rotatably connected with the inner wall of the other end of the waste paper box 12, the two moving blocks 26 are in threaded connection with the second lead screw 15, the lower ends of the two moving blocks 26 are fixedly connected with the upper ends of the first plate 21 and the second plate 22 respectively, the side of the second plate 22 away from the first plate 21 is connected with one end of the second telescopic assembly, the other end of the second telescopic assembly is connected with the upper end of the third plate 23, the outer walls of the first plate 21, the second plate 22 and the third plate 23 are in sliding connection with the inner wall of the waste paper box 12, and the second telescopic assembly is connected with the clamping port 103.

[0051] More specifically, by setting the moving partition assembly, the compressed paper scraps after being full can be collected in partitions, so as to avoid the situation that the two are close together, leading to loose or even jamming of the connecting port 102 and the dumping port 121.

[0052] As a preferred scheme of the present application, the second telescopic assembly comprises the trapezoidal plate 19, the second inner push plate 24, the second outer shell 28 and the hook plate 29, one end of the second inner push plate 24 is fixedly connected with the upper end of the side of the second plate 22 away from the first plate 21, the other end of the second inner push plate 24 penetrates into the inside of the second outer shell 28 and is slidably connected with the second outer shell 28, the outer wall of the side of the second outer shell 28 away from the one end of the second inner push plate 24 is fixedly connected with the upper end of the hook plate 29, the lower end of the hook plate 29 abuts against the side of the upper end of the third plate 23 away from the second plate 22, the bottom surface of the outer wall of the second outer shell 28 is fixedly connected with the narrow side of the trapezoidal plate 19, the upper end of the third plate 23 is provided with a trapezoidal port 231 slidably connected with the trapezoidal plate 19, and the trapezoidal plate 19, the second outer shell 28 and the hook plate 29 are slidably connected with the bayonet 103.

[0053] More specifically, by arranging the second telescopic assembly, after the first plate 21 and the second plate 22 are moved following the second lead screw 15, the second plate 22 can automatically pull the third plate 23 to match and align with the connecting port 102, so as to collect and partition the waste paper scraps compressed next time.

[0054] It should be particularly pointed out here that the total number of the third plate 23 and the second telescopic assembly is not limited, and the extra third plate 23 and the second telescopic assembly can be arranged as shown in the figure, and the connecting mode between the two third plates 23 is the same as the connecting mode between the second plate 22 and the third plate 23. Figure 15

[0055] As a preferred scheme of the present application, the inner wall of the pouring port 121 is hingedly connected with the screen 20, and the screen 20 is located at the side of the pouring port 121 away from the connecting port 102.

[0056] More specifically, by arranging the screen 20, when the waste paper box 12 is pulled out from the waste paper port 101, the waste paper scraps between the first plate 21 and the second plate 22 or between the second plate 22 and the third plate 23 can be prevented from sliding out of the pouring port 121.

[0057] And by arranging the screen 20 to be hingedly connected with the pouring port 121, the pouring port 121 can be opened when it is needed to pour the waste paper scraps, and it should be emphasized here that the screen 20 and the pouring port 121 have a certain resistance, and it is not easy to open, and a certain effort is needed, which can further reduce the situation that the waste paper scraps slide out and fall by themselves, and of course, a limiting piece such as a buckle can be added between the screen 20 and the pouring port 121, which is not limited in particular.

[0058] ​As a preferred scheme of the present application, the first telescopic assembly comprises the inclined strip 8, the straight strip 9, the first shell 10 and the first inner push plate 25, the outer wall of the first shell 10 is fixedly connected with the inner wall of the receiving opening 105, the outer wall of the other end of the first shell 10 is fixedly connected with one side of the inclined strip 8, the first shell 10 is sleeved and slidingly connected with the outer wall of one end of the first inner push plate 25, the other end of the first inner push plate 25 is fixedly connected with one side of the straight strip 9, the bottom surface of the straight strip 9 is slidingly connected with the upper surface of the first extrusion plate 7, and the upper surface of the straight strip 9 is slidingly connected with the bottom surface of the inclined strip 8.

[0059] More specifically, when the first extrusion plate 7 is pushed to move by the plurality of multi-section electric push rods 14, the gap between the first extrusion plate 7 and the receiving opening 105 is exposed, in order to avoid subsequent waste paper scraps from falling into the gap, the first telescopic assembly is arranged to automatically block the gap when the first extrusion plate 7 moves, and during the compression, the subsequent waste paper scraps are only temporarily stored above the first telescopic assembly, and when the first extrusion plate 7 returns with the plurality of multi-section electric push rods 14, the waste paper scraps originally above the first telescopic assembly can be automatically scraped into the paper falling opening 104 to wait for the next repeated compression step.

[0060] It should be particularly pointed out here that the first extrusion plate 7, the second extrusion plate 18 and the "compression" mentioned above only refer to the extrusion of the originally loose waste paper scraps into a relatively compact "waste paper block", and not strictly compressed into a whole, and the "block-shaped" paper block will be instantaneously loose without the limiting of the second telescopic assembly.

[0061] In addition, the number of the first inner push plate 25 is not limited, and is adaptively designed according to the actual moving distance of the first extrusion plate 7 and the total pushing distance of the plurality of multi-section electric push rods 14, which is not limited here, and if a plurality of first inner push plates 25 are needed to be designed, the connection diagram can be seen from Figure 13 , in addition to the innermost first inner push plate 25 (which is actually fixed with the first extrusion plate 7), the straight strip 9 is arranged on the other first inner push plates 25, so that the thickness above the first extrusion plate 7 can be blocked to avoid the occurrence of paper scraps.

[0062] In summary, as shown in Figures 1 to 16 , when the automatic cleaning type intelligent accounting paper shredder in the present application is used, first, the main switch on the top shell 2 is turned on, and then the accounting paper (hereinafter referred to as whole paper) to be pulverized is inserted through the paper inlet 201, and the whole paper inserted into the paper inlet 201 is broken into powder (hereinafter referred to as shredded paper) when passing through the crushing blade between the paper inlet 201 and the paper falling opening 104.

[0063] Subsequently, the shredded paper falls into the paper outlet 104 by gravity, and then gradually reaches a set height in the paper outlet 104 as the continuous paper breaking continues. At this time, the control system in the top shell 2 starts the multi-section electric push rod 14, and the output end of the multi-section electric push rod 14 extends outward, thereby pushing the first extrusion plate 7 connected thereto to move in the direction of the second extrusion plate 18;

[0064] While the first extrusion plate 7 is moving, the first inner push plate 25 connected to the first extrusion plate 7 also extends outward at this time. When the first inner push plate 25 extends to the top end, it pulls the second first inner push plate 25 to move outward. Then, the above-mentioned mode is repeated until the first extrusion plate 7 moves to the edge of the connecting port 102 (or only one first inner push plate 25 reaches the specified position);

[0065] At this time, the multi-section electric push rod 14 automatically stops when it reaches the telescopic top end. The control system in the top shell 2 starts the first motor 16 again. The output end of the first motor 16 rotates with the first lead screw 13, which in turn pushes the connecting block 17 and the second extrusion plate 18 from the other side of the paper outlet 104. The paper scraps compressed into a plate shape by the first extrusion plate 7 are pushed to the connecting port 102 and enter the waste paper box 12 (when not compressed, although the connecting port 102 is open, it does not affect the natural sliding of the waste paper scraps into the waste paper box 12 because of the compression in the later step);

[0066] Because the width of the waste paper box 12 is smaller than the width of the paper outlet 104, when the second extrusion plate 18 pushes the plate-shaped waste paper scraps into the waste paper box 12, it will be compressed again to compress the plate-shaped paper scraps into a column shape. The column-shaped waste paper scraps will be located between the first plate 21 and the second plate 22. Then, the first motor 16 is turned off, and at the same time, the second motor 27 is started;

[0067] The output shaft of the second motor 27 rotates with the second lead screw 15, which in turn threadedly connects the two moving blocks 26 connected to the first plate 21 and the second plate 22. The movement of the two moving blocks 26 simultaneously moves the first plate 21 and the second plate 22, thereby moving the column-shaped paper scraps between the first plate 21 and the second plate 22 to the direction of the separation net 20;

[0068] When the left side (close to the paper scraps) of the second plate 22 moves from the left side of the connecting port 102 to the right side of the connecting port 102, the second plate 22 moves with the second inner push plate 24 at this time. When the second inner push plate 24 moves to the top end inside the second outer shell 28, the second inner push plate 24 moves with the second outer shell 28;

[0069] When the left side of the second plate 22 moves to the right side of the connecting port 102, the hook plate 29 at the end of the second shell 28 is placed on the surface of the third plate 23, then the first plate 21 and the second plate 22 continue to move by the thickness of the plate, at this time, the right side of the second plate 22 is flush with the right side of the connecting port 102, and the left side of the third plate 23 is flush with the left side of the connecting port 102 (equivalent to the original position of the first plate 21 and the second plate 22);

[0070] After the second full, the columnar paper scraps in the second full enter the space between the second plate 22 and the third plate 23 for re-collection, in addition, because the number of the third plate 23 is not limited, if the space inside the waste paper port 101 and the waste paper box 12 is sufficient, the first third plate 23 will be pulled to the position of the connecting port 102 again, so that the subsequent collection can continue;

[0071] After the first plate 21 and the second plate 22 move to the position of the partition net 20, at this time, the second motor 27 is turned off, and the first motor 16 is started in reverse, at this time, the first lead screw 13 brings the second pressing plate 18 back to the original position, then the multi-section electric push rod 14 is started, and the first pressing plate 7 is also brought back to the original position;

[0072] At the same time when the first pressing plate 7 is reset, the paper scraps that fall on the first inner pushing plate 25 will slide into the paper falling port 104 due to gravity, and even if the paper scraps are stuck to the surface of the first inner pushing plate 25 due to static electricity or other reasons, because the first inner pushing plate 25 is received in the first shell 10, the paper scraps will be blocked by the outer wall of the first shell 10, so as to be forced to fall into the paper falling port 104;

[0073] After repeating the above steps for several times, when the waste paper box 12 collects a proper amount of columnar paper scraps (here, the number of the columnar paper scraps collected in the waste paper box 12 can be displayed on the display screen of the top shell 2 through the PLC controller), the waste paper box 12 is pulled out from the waste paper port 101, then the partition net 20 is opened, and then the paper scraps are poured into the external garbage can, which is convenient and easy to operate; through the above steps, three full one empty (or more times) can be realized, and when one full two full (or more times), the paper crushing can continue without stopping, so as to improve the paper crushing efficiency.

[0074] As a preferred scheme of the present application, the inner wall of the paper falling port 104 away from the receiving port 105 is fixedly connected with an inclined plate 6, the bottom surface of the inclined plate 6 is provided with a moving port 601, the first lead screw 13 is located in the moving port 601, and the connecting block 17 is in sliding connection with the moving port 601.

[0075] More specifically, by setting the inclined plate 6, an obstruction can be provided above the moving path of the second extrusion plate 18, so that when the second extrusion plate 18 moves, the subsequently falling paper scraps will not fall on the side of the second extrusion plate 18 away from the connecting port 102, avoiding the blockage when the second extrusion plate 18 returns.

[0076] As a preferred scheme of the present application, the waste paper box 12 is fixedly connected with a closing door 11 away from the paper falling port 104, and the upper end of the closing door 11 is fixedly connected with a fixed plate 3 which is detachably connected with the collecting box 1 through bolts.

[0077] More specifically, by setting the closing door 11 and the fixed plate 3, a mechanical rigid connection can be provided between the waste paper box 12 and the collecting box 1, avoiding that the waste paper box 12 is automatically pushed away when the second extrusion plate 18 pushes the compressed paper scraps.

[0078] As a preferred scheme of the present application, the top shell 2 is embedded with a monitoring sensor 5 near the collecting box 1, and the monitoring end of the monitoring sensor 5 faces the paper falling port 104.

[0079] More specifically, by setting the monitoring sensor 5, the capacity of the paper scraps inside the collecting box 1 can be monitored in real time, so as to timely start the multi-section electric push rod 14.
