Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 As shown, a paper cutting mechanism includes a workbench 1. A fixing frame 2 is fixedly connected to the top of the workbench 1. A hydraulic rod 3 penetrates through the top of the fixing frame 2. A cutting knife 4 for cutting paper is bolted to the output end of the hydraulic rod 3. A mounting plate 21 is fixed to the left side of the fixing frame 2, and a first electric push rod 10 is fixed in front of the mounting plate 21. A first pushing plate 17 for leveling the paper is bolted to the output end of the first electric push rod 10. A concave plate 11 is fixed to the right side of the fixing frame 2. A second electric push rod 12 is fixed to the right side of the concave plate 11, and a second pushing plate 18 is bolted to the output end of the second electric push rod 12. A pressing structure 13 for pressing the paper is arranged on the left side of the fixing frame 2. A movable plate 5 is movably connected to the top of the workbench 1. A placing plate 7 is arranged above the movable plate 5. A folding plate 8 is fixed to the top of the placing plate 7. A first motor 6 is arranged inside the movable plate 5. The output shaft of the first motor 6 is fixed to the bottom of the placing plate 7. A moving structure 9 for driving the movable plate 5 to move is arranged inside the workbench 1.

[0023] The moving structure 9 includes a second motor 91, a screw rod 92, a screw sleeve 93 and a connecting plate 94. The second motor 91 is fixed to the left side of the workbench 1. The output shaft of the second motor 91 is fixed to one end of the screw rod 92. The other end of the screw rod 92 is rotatably connected to the inner wall of the workbench 1. The surface of the screw rod 92 is threadedly connected to the inside of the screw sleeve 93. The top of the screw sleeve 93 is fixed to one end of the connecting plate 94. The other end of the connecting plate 94 is fixed to the bottom of the movable plate 5. Thus, when driving the movable plate 5 to move, the second motor 91 can be started to drive the screw rod 92 to rotate, and at the same time drive the screw sleeve 93 to move to the right, and drive the connecting plate 94 and the movable plate 5 to move together.

[0024] The resisting structure 13 includes a third motor 131, a gear 132, a rack plate 133 and a pressing plate 134. The third motor 131 is fixed to the left side of the top of the fixing frame 2 through a support plate. The output shaft of the third motor 131 is fixed to one side of the gear 132. The surface of the gear 132 is meshed with the rack plate 133. The surface of the rack plate 133 is movably connected to the inside of the support plate. The bottom of the rack plate 133 is rotatably connected to the top of the pressing plate 134. Before cutting, the third motor 131 can be started to drive the gear 132 to rotate, and at the same time drive the rack plate 133 and the pressing plate 134 to move downward to press the paper, thereby improving the flatness during subsequent cutting.

[0025] Chutes 14 are provided on the front and rear sides of the inner side of the top of the workbench 1. Sliders 15 are fixed to the front and rear sides of the movable plate 5. The surface of the slider 15 is slidably connected to the inside of the collection box 16. Thus, the movable plate 5 can be assisted in being limited, facilitating its left and right movement.

[0026] A circular groove 20 is provided on the top of the movable plate 5. Two sides inside the circular groove 20 are both connected with balls 19 in a rolling manner, and the top of the ball 19 is fixed to the bottom of the placing plate 7. Thus, the placing plate 7 can be assisted in being supported and the stability during its rotation can be maintained.

[0027] A collection box 16 for collecting debris is provided on the right side of the workbench 1. Thus, it is convenient to collect and process the debris after cutting in a unified manner.

[0028] Working principle: When in use, first place the paper on the top of the placement plate 7 so that the corners of the paper are in contact with the inner side of the folding plate 8. Then, drive the movable plate 5 to move to the right through the moving structure 9. After moving to the desired position, the first electric push rod 10 can be started to drive the first push plate 17 to move backward, so as to align the paper front and back. Then, start the second electric push rod 12 to drive the second push plate 18 to move to the left, so as to align the left and right sides of the paper. After the alignment is completed, the top of the paper can be pressed by the pressing structure 13. Then, start the hydraulic rod 3 to drive the cutting knife 4 to move downward to cut the paper. When the length of the paper is cut, when cutting the width of the paper, the cutting knife 4 can be raised back to the starting position. At this time, the pressing of the paper by the pressing structure 13 remains unchanged. Then, start the first motor 6 to drive the placement plate 7 to rotate so that the width of the paper is on the right side. Then, cutting can be carried out again.
