[0022] Auxiliary structures are provided below the two blowers 7 on the collection box 5. The auxiliary structure includes an L-shaped pressing plate 13 which is slidably connected to the collection groove 6. Two second electric telescopic rods 12 are arranged on the top of the L-shaped pressing plate 13. Both of the two second electric telescopic rods 12 are inserted into the interior of the collection box 5 and fixedly connected thereto. The output ends of the two second electric telescopic rods 12 are fixedly connected to the L-shaped pressing plate 13. A box plate 15 is rotatably connected to one side of the interior of the collection box 5 by a rotating shaft. The L-shaped pressing plate 13 is slidably connected to the box plate 15. Clasps 16 which cooperate with each other are arranged on one side of the collection box 5 and the box plate 15. By means of the arranged second electric telescopic rods 12, the L-shaped pressing plate 13 moves longitudinally, so that the collected paper scraps are extruded by the L-shaped pressing plate 13, improving the storage space of the device for waste scraps. At the same time, by opening the clasp 16, it is convenient to rotate the box plate 15, thus facilitating the cleaning of the waste scraps inside the collection box 5.

[0023] A first lead screw 17 is arranged on one side of the U-shaped fixing block 3 away from one of the side plates 2. The first lead screw 17 penetrates through the U-shaped fixing block 3 and is threadedly connected thereto.

The T-shaped sliding plate 27 penetrates through the moving plate 4 and is slidably connected thereto. An auxiliary plate 28 is arranged at the top of the T-shaped sliding plate 27. Two compression springs 30 are fixedly installed on both sides of the bottom of the auxiliary plate 28 corresponding to the T-shaped sliding plate 27. One end of each of the plurality of compression springs 30 away from the auxiliary plate 28 is fixedly connected to the moving plate 4. A plurality of insertion rods 29 are fixedly installed on both sides of the bottom of the auxiliary plate 28 corresponding to the T-shaped sliding plate 27. Each of the plurality of insertion rods 29 is inserted into the moving plate 4 and is slidably connected thereto. Slots matching the insertion rods 29 are formed in the T-shaped sliding plate 27. By rotating the second lead screw 24, the moving plate 4 on its outer side moves longitudinally, which further facilitates moving the pressing paper plate 26 according to the thickness of the paper to be cut. The pressing paper plate 26 arranged plays a role of pressing and limiting when cutting the paper, so that it is more convenient to cut the paper. By moving the insertion rods 29 upward to release the restriction on the T-shaped sliding plate 27, it is convenient to move the pressing paper plate 26, so as to facilitate adjusting the restriction range of the pressing paper plate 26 according to the length of the cut paper.

[0025] A guide rod 22 is arranged on one side of the U-shaped fixing block 3 away from the other side plate 2. The guide rod 22 is fixedly connected to the other side plate 2. The guide rod 22 penetrates through the U-shaped fixing block 3 and is slidably connected thereto. L-shaped limiting blocks 23 are fixedly installed on both corresponding sides of the moving plate 4. Both of the two L-shaped limiting blocks 23 are inserted into the U-shaped fixing block 3 and are slidably connected thereto. The guide rod 22 arranged makes the U-shaped fixing block 3 more stable when moving horizontally, and the L-shaped limiting blocks 23 arranged play a role in restricting the longitudinal moving position of the moving plate 4. Transparent windows 14 are arranged on the collection box 5 on one side of the two L-shaped pressing plates 13. A rubber pad 32 is fixedly installed at the bottom of the base 1. A controller 31 is embedded on one side of the base 1. The controller 31 is electrically connected to the two blowers 7 and the first electric telescopic rod 9. The transparent windows 14 arranged facilitate observing the amount of waste chips inside the collection box 5. The controller 31 arranged controls the devices on this device.

[0026] In summary, when the automatic paper cutter with a chip removal device is in use, the position of the U-shaped fixing block 3 is adjusted according to the position where the paper needs to be cut. Manually rotate the handle 20 to drive the worm 19 to drive the worm wheel 18 to rotate. Due to the self-locking performance of the worm wheel 18 and the worm 19, after the U-shaped fixing block 3 is moved to the appropriate position, it is prevented from moving. At the same time, the guide rod 22 is provided to make the U-shaped fixing block 3 more stable during lateral movement. At the same time, one side of the paper to be cut is aligned with the baffle 21 to facilitate the cutting operation. At the same time, rotate the second lead screw 24 to make the moving plate 4 on its outer side move longitudinally, which further facilitates the movement of the pressing plate 26 according to the thickness of the paper to be cut. At the same time, the L-shaped limit block 23 is provided to make the moving plate 4 more stable during longitudinal movement and prevent the moving plate 4 from rotating with the second lead screw 24.

[0027] The pressing plate 26 is provided to play a role of pressing and limiting during paper cutting, so that the paper cutting is more convenient. The restriction on the T-shaped sliding plate 27 is released by moving the insertion rod 29 upward, so as to facilitate the movement of the pressing plate 26, and thus facilitate the adjustment of the restriction range of the pressing plate 26 according to the length of the paper to be cut. And a plurality of compression springs 30 are provided to make the auxiliary plate 28 reset after moving.

[0028] The two first electric telescopic rods 9 operate synchronously to drive the fixed plate 10 to drive the cutting knife 11 to move longitudinally. Then, the paper cutting operation is realized through the cutting knife 11 provided. After the paper is taken, there are waste chips generated after cutting on the top of the base 1. By operating two blowers 7, a plurality of connecting pipes 8 absorb the waste chips into the interior of the collection tank 6. And through the filter holes provided in the L-shaped pressing plate 13, the waste chips are prevented from being absorbed into the blower 7 to cause blockage. And the second electric telescopic rod 12 is provided to make the L-shaped pressing plate 13 move longitudinally. Then, the collected paper scraps are squeezed by the L-shaped pressing plate 13 to improve the storage space of the waste chips of the device. At the same time, when the second electric telescopic rod 12 moves the L-shaped pressing plate 13 down to the maximum limit, one side height of the L-shaped pressing plate 13 is still higher than the top of the collection tank 6, preventing the waste chips from being collected on the top of the L-shaped pressing plate 13 to damage the blower 7. At the same time, by opening the buckle 16, it is convenient to rotate the box plate 15, so as to facilitate the cleaning of the waste chips inside the collection box 5.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
