A support member for supporting the upper support platform is vertically arranged between the upper support platform and the lower support platform. A pressing plate for extruding corrugated cardboard is arranged between the upper support platform and the workbench. A driving assembly for driving the pressing plate to move in the vertical direction is arranged on the upper support platform. A limiting assembly for limiting the corrugated cardboard is also vertically arranged on the workbench. The advantage of this utility model is that the corrugated cardboard is placed on the workbench surface, and the driving assembly drives the paper pressing assembly to move in the vertical direction to extrude the corrugated cardboard. Through the limiting effect of the limiting assembly, the corrugated cardboard will not be skewed or offset during the falling process, making the extrusion effect better and improving work efficiency.

[0031] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Please refer to Figures 1 - 5 , the present utility model provides the following technical solution: A paper pressing device with adjustable paper pressing force, which includes a placement table 1. A support frame 2 is installed on the upper side of the placement table 1. A paper pressing screw rod 6 is threadedly connected to the middle of the support frame 2. The lower end of the paper pressing screw rod 6 is rotatably connected to a paper pressing plate 5; a limiting groove 3 is opened inside the support frame 2; limiting blocks 4 are installed on both the left and right sides of the paper pressing plate 5;

[0033] Further, the limiting blocks 4 extend into the interior of the limiting groove 3 and are slidably connected to the limiting groove 3. The limiting blocks 4 are symmetrically arranged with respect to the longitudinal center line of the paper pressing plate 5. The movement of the paper pressing plate 5 is limited by the limiting blocks 4, so that the paper pressing plate 5 moves vertically following the rotation of the paper pressing screw rod 6;

[0034] Rotate the paper pressing screw rod 6. The lower end of the paper pressing screw rod 6 rotates on the paper pressing plate 5. At the same time, the paper pressing screw rod 6 rotates and moves downward on the support frame 2 connected by threads, thereby driving the paper pressing plate 5 to move downward. At this time, the limiting blocks 4 installed on the side of the paper pressing plate 5 slide in the limiting groove 3 to ensure the vertical movement of the paper pressing plate 5. Use the paper pressing plate 5 to press the paper. By controlling the number of turns of rotation of the paper pressing screw rod 6, the paper pressing force of the paper pressing plate 5 can be adjusted to avoid damaging the paper. When the paper pressing plate 5 drives the calibration frame 12 to move downward, the calibration frame 12 contacts the placement table 1 and is stressed, so that the calibration frame 12 moves upward under force. The calibration frame 12 squeezes and stores energy in the compression spring 13. At the same time, the calibration frame 12 slides on the mounting block 11 to ensure the smooth movement of the paper pressing plate 5 while limiting the paper;

[0035] Furthermore, first through grooves 7 are opened on both the front and rear sides of the paper pressing plate 5. A bidirectional adjustment screw rod a9 is rotatably connected inside the first through grooves 7. Second through grooves 8 are opened on both the left and right sides of the paper pressing plate 5. A bidirectional adjustment screw rod b10 is rotatably connected inside the second through grooves 8. An adjustment assembly for calibrating and limiting the paper is arranged on the paper pressing plate 5; the adjustment assembly includes mounting blocks 11 threadedly connected to the outside of the bidirectional adjustment screw rod a9 and the bidirectional adjustment screw rod b10. A calibration frame 12 penetrates through the inside of the mounting blocks 11. A compression spring 13 is connected between the calibration frame 12 and the mounting blocks 11;

[0036] Specifically, the thread distribution directions of the front and rear sections of the bidirectional adjusting screw rod a9 are opposite. Mounting blocks 11 are connected to both sections with opposite thread distributions of the bidirectional adjusting screw rod a9. When the bidirectional adjusting screw rod a9 rotates, it can control the simultaneous reverse movement of the mounting blocks 11 distributed on the front and rear sides, enabling the calibration frames 12 on the front and rear sides to push and arrange the front and rear sides of the paper. The thread distribution directions of the left and right sections of the bidirectional adjusting screw rod b10 are opposite. Mounting blocks 11 are connected to both sections with opposite thread distributions of the bidirectional adjusting screw rod b10. When the bidirectional adjusting screw rod b10 rotates, it can control the simultaneous reverse movement of the mounting blocks 11 distributed on the left and right sides, enabling the calibration frames 12 on the left and right sides to push and arrange the left and right sides of the paper. The positions of the bidirectional adjusting screw rod a9 and the bidirectional adjusting screw rod b10 are staggered from each other, and the bidirectional adjusting screw rod a9 and the bidirectional adjusting screw rod b10 are distributed in a mutually perpendicular direction, which can prevent the bidirectional adjusting screw rod a9 and the bidirectional adjusting screw rod b10 from jamming each other and ensure the smooth operation of the bidirectional adjusting screw rod a9 and the bidirectional adjusting screw rod b10. The calibration frame 12 has a "hui" - shaped structure. The calibration frame 12 is slidably connected to the mounting block 11, and the calibration frame 12 and the mounting block 11 form an elastic structure through a compression spring 13, which can ensure that while the calibration frame 12 pushes and arranges the paper, it can move flexibly, avoiding the calibration frame 12 from hindering the movement of the pressing plate 5.

[0037] The position of the calibration frame 12 can be adjusted according to the size of the materials to be bound in advance. Rotate the bidirectional adjusting screw rod a9, and the bidirectional adjusting screw rod a9 drives the mounting block 11 thread - connected to the outer side to slide in the first through - slot 7. Since the thread distribution directions of the front and rear sections of the bidirectional adjusting screw rod a9 are opposite, it can drive the symmetrically distributed mounting blocks 11 to move in the opposite direction simultaneously. When the bidirectional adjusting screw rod a9 is rotated clockwise, it can control the relative movement of the mounting blocks 11, and when the bidirectional adjusting screw rod a9 is rotated counterclockwise, it can drive the mounting blocks 11 to move away from each other, so as to flexibly adjust the distance between the symmetrically distributed calibration frames 12 to make it fit the front and rear sides of the materials, push and calibrate them and limit their positions. By controlling the rotation of the bidirectional adjusting screw rod b10, it can drive the mounting block 11 thread - connected to the outer side of the bidirectional adjusting screw rod b10 to slide in the second through - slot 8. Since the thread distribution directions of the left and right sections of the bidirectional adjusting screw rod b10 are opposite, it can drive the symmetrically distributed mounting blocks 11 to move in the opposite direction simultaneously. When the bidirectional adjusting screw rod b10 is rotated clockwise, it can control the relative movement of the mounting blocks 11, and when the bidirectional adjusting screw rod b10 is rotated counterclockwise, it can drive the mounting blocks 11 to move away from each other, so as to flexibly adjust the distance between the symmetrically distributed calibration frames 12 to make it fit the left and right sides of the materials, push and calibrate them and limit their positions. After the paper is stacked on the placing table 1, when the pressing plate 5 drives the calibration frame 12 to move downward, the calibration frame 12 can arrange the paper and ensure its neat stacking before the paper is flattened.
