At the same time, see Figure 3 , in order to ensure that the T-shaped plate 503 displacement will not be shaken and contact with the rotating broken roller 2, need to limit the electric push rod 501 and the connecting plate 502, the electric push rod 501 top end is fixedly connected in the housing 1 inner top end two sides respectively, the connecting plate 502 relative to one side is slidably connected in the housing 1 inner two sides respectively, the T-shaped plate 503 two ends are fixedly connected in the connecting plate 502 relative to one side bottom respectively; In addition, see Figures 2-4 , in order to prevent the L-shaped plate 505 from exposing gap after excessive displacement and causing the paper file to escape from the range, the movement direction and range of the L-shaped plate 505 need to be limited, the bottom end of both sides of the connecting plate 502 is abutted with the bracket 506, the bracket 506 is fixedly connected with the inner two sides of the housing 1 respectively away from one side, the upper part of the broken roller 2 is rotatably connected with the arc-shaped plate 507, the two ends of the front and rear arc-shaped plates 507 are fixedly connected with the inner two sides of the housing 1, and the top ends of the front and rear arc-shaped plates 507 are slidably connected with the bottom ends of the L-shaped plates 505; In addition, seeFigure 2 As shown more efficiently to concentrate paper documents, the need to break the roller 2 above the area for proper shielding, housing 1 within the upper front and rear side are fixedly connected with the inclined plate 8, the top of the front and rear side of the inclined plate 8 are rotatably connected with a plurality of balls 9, the front and rear side of the inclined plate 8 are located above the L-shaped plate 505; When working, with the bill, certificate, personal identity documents, etc. Single paper documents by the housing 1 front top of the inlet is put into, it can slide along the inclined plate 8 to the two broken roller 2 contact area directly above, wherein through the uniform distribution of the ball 9 can also reduce the friction, so as to ensure that the paper documents can be reserved between the two inclined plate 8 space fall below the inclined plate 8, and the space between the two inclined plate 8 is relatively large, in order to avoid affecting the normal falling of paper documents when the T-shaped plate 503 through the space, at the same time through the inclined plate 8 can also shield the paper file in a certain extent when the small suspended matter, prevent it directly from the inlet; And with the electric push rod 501, the connecting plate 502 can be driven by the electric push rod 501 to move stably along the housing 1, and then the T-shaped plate 503 can be driven to move synchronously, in addition, the two broken roller 2 will also rotate quickly under the drive of the motor box 3, so as to ensure that the paper documents can be normally crushed after being contacted with the two broken roller 2, wherein, since the T-shaped plate 503 is directly above the effective range of mutual contact of the two broken roller 2, the downward movement of the T-shaped plate 503 can make the mutually fluffy stacked paper documents be pressed to the effective range of the broken roller 2, so as to shorten the total time required for the batch of paper documents to contact the broken roller 2, and avoid the upper paper documents to wait for the lower paper documents to be crushed by the broken roller 2 one by one before gradually entering the effective range of the broken roller 2 when fluffy stacked; At the same time, when the T-shaped plate 503, connecting plate 502 and the like move downward, the inclined rotating plate 504 can rotate to push the L-shaped plate 505 below the inclined plate 8 to move away from each other along the arc-shaped plate 507, so as to leave more space to accommodate the paper documents falling along the inclined plate 8; When the electric push rod 501 drives the connecting plate 502 and the T-shaped plate 503 to move upward, the rotating plate 504 can rotate reversely to pull the L-shaped plate 505 to move close to each other along the arc-shaped plate 507, at this time, the paper documents between the front and rear L-shaped plate 505 will move close to the T-shaped plate 503 with the movement of the L-shaped plate 505, and after the T-shaped plate 503 moves upward, most of the paper documents can be below the T-shaped plate 503, when the L-shaped plate 505 is about to completely separate from the shielding of the inclined plate 8, the electric push rod 501 drives the connecting plate 502 and the T-shaped plate 503 to move downward again, at this time, most of the paper documents concentrated below the T-shaped plate 503 can be pressed into the effective range of the two broken roller 2, so as to achieve the purpose of high-efficiency crushing of the broken roller 2 by the cooperation of the T-shaped plate 503 and the L-shaped plate 505, and avoid wasting too much time in large-scale crushing operation. Further, the housing 1 can provide stable support for the electric push rod 501, so as to ensure that the electric push rod 501 can exert smooth force on the connecting plate 502, and the bracket 506 can limit the limit downward position of the connecting plate 502 and the T-shaped plate 503, so as to prevent the connecting plate 502 and the T-shaped plate 503 from excessively moving downward and contacting the rotating crushing roller 2, and prevent the L-shaped plates 505 on the front and back sides from excessively moving away from each other due to the action of the rotating plate 504, and then the L-shaped plates 505 are out of contact with the arc-shaped plate 507, and a gap is exposed for the paper documents to leave the working range of the crushing roller 2.

[0022] Further, referring to Figures 3-5 As shown in the figure, in order to avoid the paper documents from being too concentrated after being put into the paper shredder, it is necessary to transfer the paper documents accumulated on the surface of the crushing roller 2, and the flat pushing mechanism 6 includes a double-headed screw rod 601, both ends of the double-headed screw rod 601 are fixedly connected with gears 602, both sides of the connecting plate 502 are driven by the gear 602 through the rack 603, both sides of the double-headed screw rod 601 are provided with sliding blocks 604 connected with the vertical plate 605, both sides of the gear 602 are engaged on the rear side of the rack 603, both sides of the rack 603 are fixedly connected on the rear side of the connecting plate 502, both sides of the sliding block 604 are threadedly connected on the outside of the double-headed screw rod 601, and both ends of the sliding block 604 are fixedly connected on the top end of the vertical plate 605, Secondly, referring to Figures 3-6 As shown in the figure, in order to prevent the surface of the rotating double-headed screw rod 601 from winding the paper documents and affecting the normal use, and to guide the movement of the sliding block 604, the double-headed screw rod 601 is provided with a sleeve 606, both sides of the sliding block 604 are slidingly connected in the inside of the sleeve 606, both ends of the sleeve 606 are fixedly connected in both sides of the housing 1, and both ends of the double-headed screw rod 601 are rotatably connected in both sides of the housing 1. When working, the connecting plate 502 moves in a reciprocating straight line in the vertical direction, which can drive the rack 603 to move synchronously, and since the rack 603 is engaged with the gear 602, and the double-headed screw rod 601 is coaxial with the gear 602, when the connecting plate 502 moves, the double-headed screw rod 601 and the gear 602 can reciprocate in the positive and negative directions, and then since the sliding block 604 on the surface of the double-headed screw rod 601 is limited by the reserved groove in the inside of the sleeve 606, when the double-headed screw rod 601 reciprocates, the sliding block 604 can drive the vertical plate 605 to move in a reciprocating straight line in the horizontal direction, and at this time, if the paper documents are concentrated in a certain area on the surface of the crushing roller 2 due to the standing position of the staff or the habit of putting the paper documents, etc., the upper layer of the paper documents can be scattered and pushed to most positions on the surface of the crushing roller 2 by the vertical plate 605, so as to fully utilize the crushing roller 2, and cooperate with the guiding mechanism 5 to further accelerate the crushing of each batch of paper documents; In addition, the double-headed screw 601 and the gear 602 can be shielded by the sleeve 606 to prevent the double-headed screw 601 and the gear 602 from being wrapped with paper documents or fragments to affect normal use, and the double-headed screw 601 can be supported and limited by the shell 1 to prevent displacement during rotation of the double-headed screw 601, and the vertical plate 605 is located at the rear side of the T-shaped plate 503, so that they do not interfere with each other during movement, and the T-shaped plate 503 will not move up to the horizontal plane where the sleeve 606 is located.

[0023] Further, referring to Figure 7 and Figure 8 shown, in order to make full use of the internal space of the collection bin 4 and avoid frequent processing of the crushed paper document fragments, it is necessary to compress the crushed paper documents, and the compression mechanism 7 includes an electric push rod two 701, the output end of the electric push rod two 701 is fixedly connected with a push plate 702, the front end of the push plate 702 is provided with a second rotating plate 705 driving a square frame 704, a plurality of pressing plates 706 are rotatably connected to the inner side of the square frame 704, the front end of the collection bin 4 is hingedly connected with a bin door 703, the front end of the push plate 702 is rotatably connected with the second rotating plate 705 on both sides, the bottom end of the second rotating plate 705 is rotatably connected to the top end of the square frame 704 on both sides of the rear part, a plurality of sliding grooves 707 are formed in the front part of both sides of the collection bin 4, a plurality of connecting rods 708 are slidably connected inside the sliding grooves 707, and the connecting rods 708 on both sides are fixedly connected at one end close to each other; Secondly, referring to Figure 7 and Figure 8 shown, in order to ensure that the crushed paper documents fall normally into the internal area of the collection bin 4, it is necessary to guide them, and at the same time, in order to ensure the normal compression, it is necessary to limit the movement direction of the push plate 702 and the square frame 704, the rear end of the electric push rod two 701 is fixedly connected to the rear end bottom of the shell 1, the upper side of the electric push rod two 701 is provided with a baffle 709, the rear end of the baffle 709 is fixedly connected to the rear end of the shell 1, the two sides of the push plate 702 are slidably connected to the two sides inside the collection bin 4, and the outer side of the square frame 704 is slidably connected to the front side inside the collection bin 4; At the same time, referring to Figure 8 shown, in order to disperse the pressure at the contact between the electric push rod two 701 and the push plate 702 during compression, and improve the compression effect of the push plate 702 on the crushed paper documents, it is necessary to increase the contact area between the electric push rod two 701 and the push plate 702, the outer side of the output end of the electric push rod two 701 is fixedly connected with a circular truncated cone 710, and the front end of the circular truncated cone 710 is fixedly connected to the rear end of the push plate 702; When working, the crushed paper documents can fall on the surface of the baffle 709 after passing through the area where the crushing roller 2 is located, and then can slide along the inclined baffle 709 to the inside of the collection bin 4. When a certain amount of paper document fragments accumulate in the inside of the collection bin 4, the crushing work can be temporarily suspended, and the second electric push rod 701 can be started to push the push plate 702 blocked by the baffle 709 forward along the collection bin 4 in cooperation with the circular table 710. The circular table 710 can increase the contact area between the push plate 702 and the second electric push rod 701, disperse the force acting on the push plate 702, prevent deformation of the contact area between the second electric push rod 701 and the push plate 702 after long-term high-intensity compression of the paper document fragments, and avoid the difference in extrusion force of the paper document fragments on the surface of the push plate 702. At the same time, the second rotating plate 705 connected with the push plate 702 can rotate to exert a pushing force on the square frame 704 along the downward movement of the collection bin 4 when the push plate 702 moves forward. Since the square frame 704 has multiple pressing plates 706 uniformly distributed inside and the pressing plates 706 are connected with the sliding groove 707 through the connecting rod 708, the connecting rod 708 moving along the sliding groove 707 can drive the pressing plate 706 to rotate ninety degrees around the middle part connected with the square frame 704 due to the change in the angle of the sliding groove 707 during the downward movement of the pressing plate 706 along with the square frame 704. At this time, the originally vertical pressing plate 706 can be converted into a horizontal state, and the square frame 704 can be separated into upper and lower parts in cooperation with each other. At this time, the square frame 704, the pressing plate 706, and the push plate 702 can preliminarily compress part of the paper document fragments in the inside of the collection bin 4. The surface of the square frame 704 also has multiple grooves for the connecting rod 708 to enter the square frame 704 to prevent the connecting rod 708 from interfering with the square frame 704 and hindering the conversion of the pressing plate 706 into a horizontal state. When the push plate 702 returns, the square frame 704, the pressing plate 706, and the second rotating plate 705 can also return to the initial state. The paper document fragments originally above the square frame 704 and the pressing plate 706 can also fall again through the gaps between the vertical pressing plates 706 to the lower part of the square frame 704 to supplement the space left after the preliminary compression of the paper document fragments and repeat the compression step when the push plate 702 moves forward again until all the paper document fragments in the inside of the collection bin 4 are compressed. The second electric push rod 701 can be temporarily suspended, and if the compressed paper document fragments are still loose at this time, the compression can be continued when the paper document fragments in the inside of the collection bin 4 accumulate to a certain amount until the compressed paper document fragments are relatively compact. The blocking piece of the collection bin door 703 can be turned to open the door 703, and then the compressed paper document fragments can be taken out and transferred. This achieves the purpose of saving the space in the inside of the collection bin 4 and avoiding the need to frequently clean and transfer the paper fragments in the inside of the collection bin 4. After compression, the paper document fragments can also be prevented from scattering everywhere during the cleaning and transfer process, and the workload of the cleaning work can be additionally reduced.

[0024] Working principle: when in use, the downward movement of the connecting plate 502 and the T-shaped plate 503 driven by the electric push rod 501 can make the paper file actively approach the effective range of the crushing roller 2, and when the connecting plate 502 and the T-shaped plate 503 are driven upward by the electric push rod 501, the L-shaped plate 505 connected with the T-shaped plate 503 through the rotating plate 504 can be close to each other to push the paper file to the T-shaped plate 503, so that when the T-shaped plate 503 next time moves downward, the paper file under the current inclined plate 8 can be effectively sent into the effective range of the crushing roller 2, thereby accelerating the crushing efficiency of each batch of paper file, and the use of the rack 603 and the gear 602 can make the double-head screw rod 601 reverse, and then the paper file accumulated on the surface of the crushing roller 2 can be pushed to both sides through the sliding block 604 and the vertical plate 605 moving along the rear side of the T-shaped plate 503, so as to fully utilize the crushing roller 2, and the push plate 702 can be driven downward by the electric push rod 702 during the forward movement, and the sliding groove 707 and the connecting rod 708 can make the pressing plate 706 rotate by 90 degrees to separate the upper and lower sides of the square frame 704, so as to gradually complete the compression of the paper file fragments, avoiding the need for frequent cleaning of the paper file fragments.

[0025] In summary, when the motor box 3 drives the crushing roller 2 to perform the crushing operation, the single paper file can be actively and relatively uniformly contacted with the crushing roller 2 by using the guide mechanism 5 and the flat pushing mechanism 6, thereby accelerating the overall crushing progress and improving the efficiency of large batch crushing operation, and the compression mechanism 7 can effectively utilize the internal space of the collection bin 4 to prevent the need for frequent cleaning and transfer of paper file fragments generated during large batch crushing operation.
