[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, an adaptive paper cutter includes a base 1, a placement plate 2 on the base 1, a baffle 3 mounted on the placement plate 2, a bracket 4 mounted on the base 1, and a cylinder 5 mounted on the bracket 4. A cutting blade 6 is connected to the lower end of the telescopic shaft of the cylinder 5, and a pressing structure 7 is mounted on the bracket 4. A groove 9 is provided on the base 1, and an adjusting rod is provided within the groove 9. A movable door 10 is mounted on the base 1. A connecting seat inserted into the groove 9 is provided on the lower surface of the placement plate 2. The adjusting rod is threadedly connected to the connecting seat on the lower surface of the placement plate 2. A servo motor 8 is mounted at the end of the base 1, and the servo motor 8 is connected to the adjusting rod.

[0019] When using a paper cutter to cut paper, the paper is stacked on the placement plate 2, with the ends of the paper touching the baffle 3. After starting the servo motor 8 on the base 1, the servo motor 8 rotates the adjusting rod inside the groove 9. The adjusting rod, through the connecting seat, drives the placement plate 2 to move a corresponding distance on the base 1. The paper moves to the bottom of the support 4. At this time, the pressing structure 7 on the support 4 is activated to press the paper firmly. Then, the cylinder 5 is activated, and the cutting blade 6 descends through the telescopic shaft, using the cutting blade 6 to complete the paper cutting. After cutting, the cutting blade 6 and the pressing structure 7 rise and reset. After the paper is removed, the servo motor 8 drives the placement plate 2 to reset, and then the process is repeated for the next batch of paper cutting.

[0020] Through the above implementation, the material pressing structure 7 comprises a guide rod 701, a nut seat 702, a lifting frame 703, a lifting motor 704, a lead screw 705 and an elastic pressing assembly 706, the guide rod 701 penetrates through the support 4, and the lower end of the guide rod 701 is fixedly connected with the lifting frame 703, the nut seat 702 is fixed on the support 4, the lifting motor 704 is installed on the lifting frame 703, and the lifting motor 704 is connected with the lead screw 705, the lead screw 705 penetrates through the support 4 and the nut seat 702, and the lead screw 705 is threadedly connected with the nut seat 702, and the elastic pressing assembly 706 is installed on the lifting frame 703.

[0021] During the process of pressing the material, the lifting motor 704 on the lifting frame 703 is started, and the lifting motor 704 drives the lead screw 705 to rotate, and since the nut seat 702 is fixed on the support 4, the rotation of the lead screw 705 will cause the nut seat 702 to descend, thereby driving the lifting frame 703 to descend, and in this process, the guide rod 701 moves along the support 4, so as to ensure the stability of the movement of the lifting frame 703. When the elastic pressing assembly 706 contacts the paper, an acting force is applied to the paper, and at the same time, the lifting frame 703 continues to descend, the distance between the elastic pressing assembly 706 and the lifting frame 703 becomes smaller, and at the same time, a buffer protection is formed for the paper. When the lifting frame 703 contacts the material pressing component in the elastic pressing assembly 706, a rigid acting force is applied to the paper, and then the pressing work on the paper is completed. After the paper is pressed, cutting is started, and after the cutting is completed, the lifting motor 704 drives the lifting frame 703 to rise, and the acting force of the elastic pressing assembly 706 on the paper becomes smaller, and finally the lifting frame 703 drives the elastic pressing assembly 706 to rise and give way, and the staff can take away the paper for the next batch of cutting.

[0022] The elastic pressing assembly 706 comprises a receiving groove 7061, a connecting rod 7062, a pressing plate 7063, a through hole 7064, a spring 7065, a buffer rubber sleeve 7066 and a limiting plate 7067, the receiving groove 7061 is arranged on the lifting frame 703, and the lifting frame 703 is provided with a through hole in communication with the receiving groove 7061, the connecting rod 7062 is fixedly connected with the pressing plate 7063, and the connecting rod 7062 penetrates through the through hole on the lifting frame 703 and the receiving groove 7061, the through hole 7064 is arranged on the pressing plate 7063, the spring 7065 is sleeved on the connecting rod 7062, and the spring 7065 is located in the receiving groove 7061, the buffer rubber sleeve 7066 is sleeved on the upper end of the connecting rod 7062, and the limiting plate 7067 is fixedly connected with the upper end of the connecting rod 7062.

[0023] In the process of pressing, when the pressing plate 7063 contacts the paper, the lifting frame 703 continues to descend, the pressing plate 7063 and the connecting rod 7062 are lifted relative to the lifting frame 703, the spring 7065 in the receiving groove 7061 is compressed to form a buffer, the limiting plate 7067 at the upper end of the connecting rod 7062 is lifted away from the buffer rubber sleeve 7066 relative to the lifting frame 703, and when the lifting frame 703 contacts the pressing plate 7063, a rigid force is applied to the paper, and then the cutting work is performed. After the paper cutting is completed, the lifting frame 703 is lifted and the spring 7065 is elongated, and when the buffer rubber sleeve 7066 on the lifting frame 703 contacts the limiting plate 7067, a buffer is formed and the limiting plate 7067 is lifted, so that the pressing plate 7063 is lifted through the connecting rod 7062. Due to the through hole 7064, the pressing plate 7063 and the paper are not adsorbed together, thereby preventing the pressing plate 7063 from lifting with the uppermost layer of paper, and the structure is simple and the use effect is excellent.

[0024] It should be noted that by setting the pressing structure 7, the lifting motor 704, the screw rod 705, the nut seat 702, the lifting frame 703 and the elastic pressing assembly 706 are used for pressing work, and the same size pressing force can be applied to the paper stack of different thicknesses in the stroke range, thereby avoiding excessive force or insufficient force, and ensuring the normal cutting work. The elastic pressing assembly 706 is installed on the lifting frame 703 in an elastic connection mode, first performs elastic buffering during the pressing process, avoids damage to the paper caused by sudden pressing, applies a rigid force when the bottom end of the lifting frame 703 contacts the pressing plate 7063, and does not affect the pressing effect. The buffer rubber sleeve 7066 is sleeved on the upper end of the connecting rod 7062, and the buffer rubber sleeve 7066 forms a buffer between the lifting frame 703 and the limiting plate 7067 during the lifting of the lifting frame 703, thereby protecting the structures such as the lifting frame 703 and the limiting plate 7067.
