[0019] Please refer to the attached Figure 1-Figure 3 It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] The utility model proposes a paper slitting and cutting machine with adjustable cutting size. Before use, the output end of the hydraulic rod 1 is in a retracted state, the strip plate 3 is in the highest position, a pair of springs are in a naturally stretched state, the pressure plate 11 is lower than the cutting plate 12, and the movable plate 13 is located at the position farthest from the side plate 10. When using this device, first manually align a stack of papers roughly, then push one end of the paper against one side of the baffle 5, and fit the side edge of the paper to the side plate 10. Turn the turntable, the turntable drives the lead screw 7 to rotate, and the lead screw 7 drives the slider 8 to slide along the slide groove in the direction close to the side plate 10. The slider 8 drives the movable plate 13 to slide in the direction close to the side plate 10. When the side plate 10 and the movable plate 13 are in contact with the stack of papers on the opposite side, the paper is cut off. After the two sides of the paper are aligned, stop rotating the turntable. At this time, the two sides of the stack of paper are aligned. Pick up the external straight plate (a flat short plate of an ordinary rectangular parallelepiped can be used), and fit one end of the straight plate to the side plate 10. The straight plate is located on the side plate 10 and the movable plate 13. Push the straight plate. The straight plate pushes a stack of paper so that one end of the stack of paper is all attached to one side of the baffle 5. Take out the baffle 5, and the card plate 14 is separated from the card slot 9. Continue to push the stack of paper forward through the straight plate (or stand up the baffle 5 to temporarily replace the straight plate. As long as it is a regular rectangular plate, it can achieve the purpose of aligning and pushing a stack of paper). Align the cutting line of the stack of paper to the side of the cutting slot 9 close to the side plate 10, start the hydraulic rod 1, and the output end of the hydraulic rod 1 drives the strip plate 3 to slide downward, and the strip plate 3 drives A pair of guide rods slide downward, and the strip plate 3 drives the cutting plate 12, a pair of sleeves 4 and the pressure plate 11 to slide downward. The pressure plate 11 first contacts the upper side of the paper, and the strip plate 3 drives the pair of sleeves 4 to slide downward along the corresponding slide rod 2. When the lower side of the cutting plate 12 contacts the upper side of the paper, the pair of springs are in a compressed state, and the pressure plate 11 is pushed to press the paper by the rebound force of the spring (under the action of the spring, it is convenient to press papers of different thicknesses, and cooperate with the rubber layer on the outside of the pressure plate 11 to avoid indentations on the paper surface). When the output end of the hydraulic rod 1 is fully extended, the lower end of the cutting plate 12 cuts one side of the paper and is located in the cutting groove 15. The hydraulic rod 1 retracts to drive the cutting plate 12 to rise, and the strip plate 3 is restored After reaching the initial height, close the hydraulic rod 1, rotate the turntable in the opposite direction to pick up a stack of paper, turn the paper 180° to cut the other side, and when cutting the other side, push the stack of paper through the straight plate, adjust the length of the paper through the scale line pair, and push the stack of paper to the appropriate cutting position, start the hydraulic rod 1 again to cut the other side. The cutting process is the same and will not be repeated. After cutting the two opposite ends, rotate the paper 90° and cut off the remaining two sides. The operation process is the same and will not be repeated. This device is convenient for cutting paper into different sizes as required, is not limited to conventional size cutting, and has a wider range of uses. When cutting, the pressure plate 11 is used to ensure the neatness of the paper cutting.
