The guide roller 12 is restricted on the guide rail 13 and can move up and down along the guide rail 13. The first runner 10 and the second runner 11 are installed on the movable frame 9. The first runner 10 is located above the first cam 6 and always rotates in conflict with the first cam 6. The second runner 11 is located below the second cam 7 and always rotates in conflict with the second cam 7. When the rotating shaft 5 rotates, the first cam 6 and the second cam 7 drive the movable frame 9 to move up and down; the upper cutter 2 is fixed to the bottom of the movable frame 9, and the lower cutter 3 is fixed to the bottom of the box body 1.

[0027] The first cam 6 is in rolling connection with the first rotating wheel 10, and the second cam 7 is in rolling connection with the second rotating wheel 11. Specifically, the driving motor 4 drives the first cam 6 and the second cam 7 on the rotating shaft 5 to rotate simultaneously. While the first cam 6 and the second cam 7 are rotating, they are respectively in rolling connection with the first rotating wheel 10 and the second rotating wheel 11. The first cam 6 and the second cam 7 have different shapes, and their shapes are adapted to their movements. Specifically, when the convex surface of the first cam 6 contacts the first rotating wheel 10, the first cam 6 can contact the first rotating wheel 10 upward and drive the first rotating wheel 10 to move upward. At the same time, the concave surface of the second cam 7 contacts the second rotating wheel 11, and the second rotating wheel 11 moves along with the first rotating wheel 10 moves upward at the same time, that is, at this time the first rotating wheel 10 and the second rotating wheel 11 drive the movable frame 9 to move upward, and the upper cutter 2 at the bottom of the movable frame 9 moves upward accordingly, away from the lower cutter 3; the rotating shaft 5 drives the first cam 6 and the second cam 7 to rotate continuously, and the first cam 6 gradually rotates from the convex surface to the concave surface, and the contact height between the first cam 6 and the first rotating wheel 10 begins to decrease. At this time, the second cam 7 gradually rotates from the concave surface to the convex surface, and the contact height between the second cam 7 and the second rotating wheel 11 decreases accordingly. That is to say, at this time the first rotating wheel 10 and the second rotating wheel 11 drive the movable frame 9 to move downward, and the upper cutter 2 at the bottom of the movable frame 9 moves downward accordingly, close to the lower cutter 3.

[0028] With the cooperation of the guide roller 12 and the guide rail 13 , the upper cutter 2 always moves up and down in the vertical direction, thereby ensuring the movement trajectory and stability of the upper cutter 2 .

[0029] Furthermore, a mounting bracket 14 is fixed to the top of the box body 1 , and both ends of the rotating shaft 5 are mounted on the mounting bracket 14 through bearings. The rotating shaft 5 is mounted on the mounting bracket 14 to increase the rotational stability of the rotating shaft 5 .

[0030] Furthermore, a fixed frame 15 is fixed to the middle of the movable frame 9. The first rotating wheel 10 is rotatably mounted on the upper portion of the fixed frame 15, and the second rotating wheel 11 is rotatably mounted on the lower portion of the fixed frame 15. The first rotating wheel 10 and the second rotating wheel 11 are mounted on the fixed frame 15. The first rotating wheel 10 and the second rotating wheel 11 are staggered in vertical position to match the positions of the first cam 6 and the second cam 7 on the same rotating shaft 5.

[0031] The box body 1 is provided with a feed port and a discharge port 16 so that the plate can enter the box body 1 for cutting. Figure 4 A lower knife holder 17 is fixed at the bottom of the box body 1, and an upwardly inclined mounting groove 18 is provided on the top surface of the lower knife holder 17. A protruding rod 19 is provided at the bottom of the lower cutter 3. The bottom of the protruding rod 19 is inclined and movably installed in the mounting groove 18.

The sum of the inclination angle of the bottom of the lower cutter 3 and the inclination angle of the mounting groove 18 is a flat angle, and the lower knife holder 17 can move horizontally.

[0032] Specifically, the cutting surface of the lower cutter 3 is a horizontal surface. When the lower cutter 3 is installed in the lower tool holder 17, the inclined surface of the bottom of the lower cutter 3 conflicts with the inclined surface of the mounting groove 18. In this way, the horizontal direction of the cutting surface of the top of the lower cutter 3 is not affected. The limiting frame 25 is fixed to the bottom of the box body 1. A guide groove is provided on the limiting frame 25. Guide rods 20 extend from both ends of the lower cutter 3. The guide rods 20 are movably inserted in the guide groove. Since the position of the limiting frame 25 is fixed, when the lower tool holder 17 moves horizontally, under the action of the vertical guide groove, the bottom surface of the lower cutter 3 moves relative to the lower tool holder 17, and the height of the lower cutter 3 in the vertical direction changes. The distance between the lower cutter 3 and the upper cutter 2 can be fine-tuned to adapt to plates of different thicknesses.

[0033] In order to increase the stability of the lower cutter 3, a locking screw or the like may be further provided on the limiting frame 25. After the height of the lower cutter 3 is adjusted, the locking screw is passed through the guide rod 20 to further fix the lower cutter 3.

The deburring unit 231 includes a fixed plate 2311, a movable group plate 2312, a grinding piece 2313, an upper roller 2314 and a lower roller 2315. The fixed plate 2311 is fixed on the frame 22. The movable group plate 2312 can be horizontally movably arranged on the fixed plate 2311 through a first telescopic member 2316. The lower roller 2315 is driven by a driving member and is arranged on the movable group plate 2312 through a first support frame 2318. The upper roller 2314 is arranged above the lower roller 2315 and is arranged on the movable group plate 2312 through a second telescopic member 23120. The grinding piece 2313 is fixed on the movable group plate 2312 and is arranged at the front end of the upper roller 2314 and the lower roller 2315.

[0037] Furthermore, the front end of the grinding piece 2313 and the rear end of the upper roller 2314 are both provided with guide rollers 2317, and the rotation direction of the guide rollers 2317 is perpendicular to the rotation direction of the upper roller 2314. The guide rollers 2317 are arranged on the movable assembly plate 2312 through the third support frame 2319.

[0038] Furthermore, the movable group plate 2312 includes an upper movable plate 23121, a lower movable plate 23122 and an elastic component 23123. The lower movable plate 23122 is movably arranged on the fixed plate 2311 through a first telescopic member 2316. The upper movable plate 23121 is arranged above the lower movable plate 23122, and an elastic component 23123 is arranged between the two. The elastic component 23123 includes a spring member and a telescopic piston rod. The fixed end of the telescopic piston rod is fixed on the lower movable plate 23122 and the piston end is fixed on the upper movable plate 23121. The spring member is sleeved on the outside of the telescopic piston rod and fixed between the upper movable plate 23121 and the lower movable plate 23122.

[0039] Furthermore, the rear end of the box body 1 is provided with a conveying mechanism 24, referring to Figure 1 A plurality of buffer springs 26 are fixed to the bottom of the movable frame 9, and a buffer plate 27 is fixed to the bottom of the buffer springs 26. When no force is applied, the height of the buffer plate 27 is equal to or slightly less than the height of the upper cutter 2. When the upper cutter 2 and the lower cutter 3 are engaged, the buffer plate 27 abuts against the lower cutter frame 17 or the box body 1 to buffer the force applied to the movable frame 9.

[0040] Working principle: The plate first passes through the deburring mechanism 23, and the grinding piece 2313 is used to remove burrs on both sides of the plate. At the same time, the deburring mechanism 23 can also play a guiding role to adjust the plate into the center position of the box 1; according to the thickness of the plate, by changing the horizontal position of the lower tool holder 17, the height of the lower cutter 3 is adjusted, and the cutting distance between the upper cutter 2 and the lower cutter 3 is adjusted.

[0041] The plate enters the box body 1 from the feed port, and the driving motor 4 drives the rotating shaft 5 to rotate continuously. The first cam 6 and the second cam 7 continuously conflict with the first rotating wheel 10 and the second rotating wheel 11, driving the movable frame 9 and the upper cutter 2 to move up and down repeatedly, realizing intermittent cutting of the plate.

[0042] The present invention is provided with a first cam 6, a second cam 7, a first rotating wheel 10 and a second rotating wheel 11. The first cam 6 always rotates in contact with the first rotating wheel 10, and the second cam 7 always rotates in contact with the second rotating wheel 11. When the contact position of the first cam 6 and the first rotating wheel 10 gradually rotates from a concave surface to a convex surface, the first cam 6 gradually contacts the first rotating wheel 10 upward and drives the first rotating wheel 10 to move upward. At this time, the contact position of the second cam 7 and the second rotating wheel 11 gradually rotates from a convex surface to a concave surface, and the second rotating wheel 11 moves upward accordingly. The first rotating wheel 10 and the second rotating wheel 11 drive the upper cutter 2 to move upward accordingly, away from the lower cutter 3; conversely, the first rotating wheel 10 and the second rotating wheel 11 drive the upper cutter 2 to move downward, close to the lower cutter 3, to achieve cutting. During the up and down movement of the upper cutter 2, the first cam 6 and the second cam 7 jointly support the movable frame 9 to ensure the stability and repeatability of the movement of the upper cutter 2. By adjusting the rotation speed of the rotating shaft 5, the movement speed of the upper cutter 2 can be adjusted to achieve adjustment of the cutting length of the plate. The present invention can adjust the speed and precision of the upper cutter 2 moving up and down, so that cutting is more accurate and cutting quality is guaranteed.
