[0027] Example

[0028] refer to Figures 1-3 As shown, this application discloses an automatic cutting device, including a cutting tray 10, a feeding mechanism 20 and a cutting mechanism 30;

[0029] The cutting tray 10 is horizontally arranged along the first direction;

[0030] The feeding mechanism 20 includes a moving drive unit 21 located on both sides of the cutting tray 10 in the second direction and a suction robot 22 connected to the moving drive unit 21;

[0031] The cutting mechanism 30 includes a rotary drive unit 31, a frame 32, a cutting drive unit 34, an upper cutter 35, and a lower cutter 33. The rotary drive unit 31 is located at the conveying end of the cutting tray 10. The frame 32 is connected above the rotary drive unit 31. The upper cutter 35 is located inside the lower part of the frame 32. The cutting drive unit 34 is located at the top of the frame 32. The upper cutter 35 is located inside the upper part of the frame 32, connected to the cutting drive unit 34, and cooperates with the lower cutter 33.

[0032] In the specific cutting process, the suction robot 22 first suctions the cardboard and, driven by the moving drive unit 21, pulls the cardboard forward to the lower cutter 33. Then, the rotation drive unit 31 drives the frame 32 to rotate 45° to the left. After it is in position, the cutting drive unit 34 drives the upper cutter 35 to descend and cut a bevel on one side of the cardboard (after the bevel is cut, all parts are reset). Next, the rotation drive unit 31 drives the frame 32 to rotate 45° to the right. After it is in position, the cutting drive unit 34 drives the upper cutter 35 to descend and cut another bevel on the other side of the cardboard (after the bevel is cut, all parts are reset). After the above actions are completed, the moving drive unit 21 pulls the cardboard forward to move a set length, and the cutting drive unit 34 drives the upper cutter 35 to descend and cut the cardboard.

[0033] The mobile drive unit 21 of this application includes a servo screw module 211 and a linear guide rail 212 respectively disposed on both sides of the cutting tray 10 in the second direction, and an H-shaped bracket 213 connected to the servo screw module 211 and the linear guide rail 212. The suction robot 22 includes a first cylinder 221 disposed above the horizontal part of the H-shaped bracket 213, a fixture plate 222 disposed at the bottom of the H-shaped bracket 213 and connected to the piston rod of the first cylinder 221, and several pneumatic suction heads 223 disposed at the bottom of the fixture plate 222. Before feeding, the first cylinder 221 drives the fixture plate 222 to descend, and the cardboard is suctioned by the several pneumatic suction heads 223 at the bottom of the fixture plate 222. After that, the servo screw module 211 and the linear guide rail 212 cooperate to drive the H-shaped bracket 213 to move, thereby realizing the movement of the cardboard.

[0034] In one specific embodiment, the rotary drive unit 31 of this application includes a frame 311 disposed at the conveying end of the cutting tray 10, a servo motor 313 disposed at the bottom of the table surface of the frame 311 and connected to a reducer 312 by its output shaft; a frame 32 disposed on the upper surface of the frame 311 and connected to the output shaft of the reducer 312. In a specific implementation, the servo motor 313 and the reducer 312 cooperate to drive the frame 32 to rotate to the left, reset, or rotate to the right.

[0035] To facilitate the unloading of cutting waste and slit cardboard products, this application provides an outwardly extending inclined guide platform 40 at the discharge port of the frame 32. In specific implementation, a receiving box can be set on the ground corresponding to the inclined guide platform 40 to receive cutting waste and slit cardboard products. It should be noted that the operator needs to reorganize the cardboard products in the receiving box afterward.

[0036] In one specific embodiment, the cutting drive unit 34 of this application includes a second cylinder 341. The second cylinder 341 is disposed above the frame 32 and its piston rod passes through the frame 32 and is connected to the upper cutter 35. In specific implementation, the second cylinder 341 drives the upper cutter 35 to descend, which can cut beveled edges on both sides of the cardboard and slit the cardboard. In order to ensure that the second cylinder 341 can stably drive the upper cutter 35 to rise and fall, this application provides a connecting block 351 above the upper cutter 35, which is connected to the piston rod of the second cylinder 341. Two guide sleeves 321 are provided inside the upper part of the frame 32. Two guide posts 352 are provided above the connecting block 351, which pass through the two guide sleeves 321 respectively. When the second cylinder 341 drives the connecting block 351 to rise and fall, the two guide posts 352 rise and fall in the two guide sleeves 321 respectively.
