Detailed Embodiments
[0015] The following further explains the present utility model in conjunction with the drawings and specific embodiments.
[0016] Embodiment: As shown in the figure, a cutting mechanism for paper product production according to the present utility model includes a cutting table 1, a conveyor belt 2, a cutting mechanism 3 and an adjusting mechanism 4. The cutting table 1 is directly below the cutting mechanism 3. The cutting mechanism 3 is installed on the adjusting mechanism 4. The conveyor belt 2 is adjacent to the cutting table 1 and is located at the lower end of the adjusting mechanism 4. The cutting mechanism 3 is driven by the adjusting mechanism 4 to move to complete cutting. The cutting mechanism 3 includes a tool holder 5, a blade 6 and a pressing member 7. The tool holder 5 is fixed on the adjusting mechanism 4. A bayonet is opened at its lower end, and a threaded hole penetrating the bayonet is opened on the front. The blade 6 is installed in the bayonet with its cutting edge facing down. Mounting holes corresponding to the positions of the threaded holes are provided on the pressing knife. The blade 6 is fixed in the tool holder 5 through bolts. The pressing member 7 is fixed on the tool holder 5 and is elastically connected to the tool holder 5.
[0017] The pressing member 7 includes a positioning pin 12, a spring 13, a cylindrical sleeve 14 and a rubber head 15. The positioning pin 12 is fixed on the tool holder 5 and is connected to the cylindrical sleeve 14 at the lower end through the spring 13. The rubber head 15 is fixed at the lower end of the cylindrical sleeve 14. The lower end of the rubber head 15 is lower than the lower end of the blade 6, and the height of the blade 6 is always within the stroke range of the rubber head 15. During use, since the pressing member 7 is lower than the blade 6, when cutting downwards, the rubber head 15 will first press on the cardboard to fix it. Then, when continuing to press downwards, the spring 13 is compressed and the blade 6 moves downwards to cut the cardboard. When moving upwards, the spring 13 is released and the pressing member 7 resets, which can keep the position of the cardboard unchanged during cutting, prevent the blade 6 from squeezing the cardboard and causing deviation, and ensure that the cutting position is accurate.
[0018] The horizontal moving mechanism 9 and the vertical moving mechanism include a housing 16, a motor 17, a driving shaft, a sliding shaft, a slider 18 and a mounting plate 19. The housing 16 is fixed on the processing tabletop. One end of the housing 16 is provided with the motor 17. The driving shaft is installed in the housing 16 and is fixedly connected to the motor 17. The sliding shaft is rotatably connected in the housing 16 parallel to the driving shaft. The middle part of the slider 18 is fixedly connected to the driving shaft, and both ends are slidably connected to the sliding shaft. The mounting plate 19 is fixed on the slider 18. The motor 17 is connected to an external control through a wire. When the motor 17 works, it drives the driving shaft to rotate, causing the slider 18 to move on the housing 16, thereby driving the connected vertical moving mechanism to move left and right and the rotating mechanism 11 to move up and down.
[0019] A set of limiting blocks 20 located above the conveyor belt 2 are further provided on the bottom surface of the frame 8. The limiting blocks 20 are fixed in the sliding grooves of the frame 8 through bolts. The limiting blocks can adjust their positions so that the cardboard on the conveyor belt 2 always moves between the limiting blocks 20, ensuring that the position of the cardboard during cutting is accurate.
[0020] The rotating mechanism 11 includes a shaft body 21 fixed on the vertical moving mechanism. A turntable 22 is rotatably connected to the shaft body 21. A fastening bolt 23 is connected between the turntable 22 and the shaft body 21. The rotation angle between the turntable 22 and the shaft body 21 can be adjusted by loosening and tightening the fastening bolt 23. By adjusting the rotation position between the shaft body 21 and the turntable 22 through the fastening bolt 23, that is, the inclination angle of the blade 6 in the horizontal direction can be adjusted, and an inclined cutting groove can be made, which is suitable for cutting special-shaped or complex wrapping paper.
[0021] In the present utility model, the cardboard on the conveyor belt is positioned directly below the cutting mechanism through the limit block to ensure the correct position. Then, when the cutting mechanism moves downward for cutting, the pressing member first fixes the cardboard, and then the blade continues to move downward to cut the cardboard. During this process, the pressing member always fixes the cardboard without moving, which can ensure the cutting accuracy of the cardboard, ensure that the cutting position of the cardboard is accurate and without deviation, improve the yield rate of the cardboard, and has a simple structure and is convenient to use.
[0022] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
