[0037] In this embodiment, by setting the rubber pad 16, it is convenient to use the downward-moving pressing plate 7 to press and position both sides of the position of the paper to be cut, and it can avoid the situation of skew cutting and uneven cutting seams.

[0038] As a preferred embodiment, on the basis of the above structure, further, the pressing control assembly 9 includes a driving rod 91, a sleeve 92, a first extrusion column 93 and a second extrusion column 94. The left end of the driving rod 91 is fixedly connected to the output shaft of the servo motor 10. A sleeve 92 is sleeved outside the driving rod 91. The right end of the sleeve 92 is fixedly connected to a first extrusion column 93. The right end of the first extrusion column 93 is fixedly connected to a second extrusion column 94. The telescopic end of the electric push rod 11 is connected to the right side wall of the second extrusion column 94 by a bearing.

[0039] In this embodiment, by controlling the first extrusion column 93 to move leftward by the electric push rod 11, the bottom wheel 14 can be used to squeeze the frustum-shaped first extrusion column 93, so that the first extrusion column 93 is squeezed and drives the pressing plate 7 and the connecting block 12 to move downward synchronously along the first vertical axis 5 stably.

[0040] As a preferred embodiment, on the basis of the above structure, further, convex portions equal to the length of the driving rod 91 are symmetrically arranged on the outer wall of the driving rod 91, and a groove structure adapted to the convex portions on the outer wall of the driving rod 91 is provided on the inner wall of the sleeve 92. The driving rod 91 is in snap-fit sliding connection with the sleeve 92.

[0041] In this embodiment, by using the convex portions on the outer wall of the driving rod 91 and the corresponding groove structure provided on the inner wall of the sleeve 92, the driving rod 91 can not only drive the sleeve 92 to rotate synchronously, but also enable the sleeve 92 to slide and adjust on the outside of the driving rod 91.

[0042] As a preferred embodiment, on the basis of the above structure, further, the first extrusion column 93 is in a frustum shape, and the center lines of the driving rod 91, the sleeve 92, the first extrusion column 93 and the electric push rod 11 are all located on the same horizontal straight line.

[0043] In this embodiment, when the second extrusion column 94 rotates 180°, the second extrusion column 94 can squeeze the mounting rod 81, and control the mounting rod 81 to drive the cutting knife 82 to move downward synchronously along the second vertical axis 83 stably. It is convenient to cut the paper above the cutting groove 2 by using the vertically downward-moving cutting knife 82.

[0044] The working principle of the present utility model is as follows:

[0045] During use, first, the paper to be cut is inserted between the processing table 1 and the pressing plate 7, and the position of the paper to be slit is pushed above the cutting groove 2. Subsequently, the electric push rod 11 can be used to control the second extrusion column 94, the first extrusion column 93, and the sleeve 92 to move leftward synchronously. At this time, the bottom wheel 14 rotatably connected to the inner side of the bottom of the fixing frame 13 can extrude the frustum-shaped first extrusion column 93, enabling the first extrusion column 93 to be extruded and driving the pressing plate 7 and the connecting block 12 to move downward stably along the first vertical shaft 5 synchronously. At this time, the rubber pad 16 adhered to the bottom of the pressing plate 7 makes soft contact with and extrudes the paper, facilitating the pressing and positioning of both sides of the position of the paper to be cut, thereby avoiding the situations of skewed cutting and uneven cutting seams;

[0046] After the two sides of the position of the paper to be cut are pressed and positioned, the servo motor 10 is started to control the driving rod 91 to drive the sleeve 92, the first extrusion column 93, and the second extrusion column 94 that are engaged and slidably connected thereto to rotate 180° synchronously, as Figure 5 and Figure 6 shown in. Since the second extrusion column 94 is eccentrically arranged at the right end of the first extrusion column 93, the second extrusion column 94 after rotating 180° can extrude the mounting rod 81, controlling the mounting rod 81 to drive the cutting knife 82 to move downward stably along the second vertical shaft 83 synchronously. The vertically moving cutting knife 82 facilitates the cutting of the paper above the cutting groove 2, facilitating the cutting of the longer paper into an appropriate length, facilitating the subsequent folding processing of the carton, and with the settings of the first spring 6 and the second spring 84, it is convenient for the pressing control assembly 9 to reset, and the pressing plate 7 and the paper cutting assembly 8 can automatically reset;

[0047] It should be particularly noted that, as Figure 5 shown in, convex portions equal to its own length are symmetrically arranged on the outer wall of the driving rod 91, and a groove structure adapted to the convex portions on the outer wall of the driving rod 91 is provided on the inner wall of the sleeve 92. Therefore, the driving rod 91 and the sleeve 92 can not only rotate synchronously, but also relatively slide between them.

[0048] The above is only a preferred specific embodiment of the present invention, and it is not intended to limit the protection scope of the present invention; all equivalent changes, modifications, substitutions, and variations made by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning, or limited experiments shall fall within the protection scope determined by the claims.
