Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a deviation-correcting sliding mechanism of a paper cutter. Background Art

[0002] Paper cutters are traditional products used to handle paper cutting needs in the later stages of printing. They have evolved from mechanical paper cutters to tape-controlled paper cutters, and then to microcomputer-controlled, color-display, full-image operation-guided visual processing, and computer-aided cutting systems with external programming and editing of production data, making production preparation time shorter, cutting more accurate, labor-intensive, and safer to operate.

[0003] Existing paper cutters on the market are in use. When using traditional paper cutters, the operator usually directly pushes the paper to be cut under the blade and then cuts it. This operation method may cause the paper to be cut to shift during the process, thereby affecting the final cutting effect of the paper. Utility Model Content

[0019] Please refer to the attached Figure 1-Figure 5 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] The utility model proposes a deviation correction sliding mechanism for a paper cutter. Before use, a pair of deviation correction plates 18 are at the farthest relative position, the output end of the electric push rod 4 is in a contracted state, a pair of springs 16 are in a naturally stretched state, and a pressure plate 6 is located below a cutter 5. Figure 1As shown, when using the device, the sensing value range of the pressure sensor 12 is set through the control panel 1. When in use, the lower ends of a stack of paper are aligned and placed on the workbench 8, and the paper is pushed toward the direction close to the cutter 5. The paper slides along a set of rollers 9 to reduce the friction between the paper and the workbench 8, and prevents the paper at the bottom from being separated from the stack of paper due to friction. When one end of the paper is pushed out to a length suitable for cutting, the paper is stopped from being pushed, and the motor 10 is started. The motor 10 drives the lead screw 11 to rotate, and the lead screw 11 drives a pair of sliders 13 to slide in the through slot toward each other, and the pair of sliders 13 drives the corresponding mounting plates 7 toward each other. The pair of mounting plates 7 drive the corresponding deflection correcting plates 18 to slide in the direction of approaching each other through the corresponding pressure sensors 12. When the opposite side of the pair of deflection correcting plates 18 is attached to the side of the paper, the pair of deflection correcting plates 18 reversely squeeze the sensing end of the corresponding pressure sensor 12, and the pair of deflection correcting plates 18 drive the corresponding pair of guide rods to slide along the holes of the corresponding mounting plates 7. When the pressure sensed by the pair of pressure sensors 12 reaches the set sensing value range, the motor 10 stops rotating. At this time, the pair of deflection correcting plates 18 limit the deflection of the paper. After the paper is corrected, the electric push rod 4 is started, and the electric push rod 4 drives the cutting plate 17 to slide downward. The cutting plate 17 drives the corresponding pair of guide rods 2 3 to slide downward, the cutting plate 17 drives the cutter 5 and the pair of annular rings 14 to slide downward, the pair of annular rings 14 drive the pressure plate 6 to slide downward through the corresponding guide rods 3 15 and the springs 16, the lower side of the pressure plate 6 first contacts the paper, the cutting plate 17 continues to slide downward, the pair of annular rings 14 slide downward along the corresponding guide rods 3 15, the pair of annular rings 14 press the corresponding springs 16 downward, the pair of springs 16 are both in a compressed state, the resilience of the pair of springs 16 jointly pushes the pressure plate 6, so that the pressure plate 6 flattens and presses one end of the paper, the cutting plate 17 continues to slide downward, when the electric push When the output end of the rod 4 is fully extended, the cutter 5 is in the lowest position, and the cutter 5 cuts one end of a stack of paper. After standing for a while, the output end of the electric push rod 4 retracts to the initial position, and the electric push rod 4 stops. At this time, the cutter 5 has completed cutting one end of the stack of paper. The device achieves the purpose of limiting the deviation of the paper through the correction structure. When cutting, one end of the paper is first flattened and pressed by the pressure plate 6, and then the cutter 5 is used to cut one end of the paper, so that the cut end of the paper is neat and flat after cutting. The device is suitable for trimming a stack of paper, but not for trimming one or several sheets of paper. The thickness of a stack of paper is ≥2cm.
