The connecting column 601, the flattening mechanism 3 is arranged below the bottom surface of the sliding plate 6. In this embodiment, the edge of the carton is pressed by the fixing mechanism 4 to fix the carton, and then the carton is flattened by the flattening mechanism 3. The motor 5 drives the screw 501 to rotate, thereby driving the sliding plate 6 to move. The flattening mechanism 3 moves with the sliding plate 6 on the bottom surface of the sliding plate 6 to flatten the carton. When the sliding plate 6 moves to the edge of the carton, the connecting column 601 pushes the fixing mechanism 4 away from the carton, so that the flattening mechanism 3 flattens the edge of the carton. When the flattening mechanism 3 completes the flattening work and moves in the reverse direction, the spring 405 drives the telescopic rod four 404 to reset, so that the fixed roller still fixes the carton.

[0028] Wherein, the fixing mechanism 4 comprises a movable plate 401, a fixed pressure roller 402 and a second cylinder 407, a bearing block 406 cooperating with a connecting column 601 is arranged on the side of the movable plates 401 close to each other, a plurality of telescopic rods 404 are arranged on the side of the movable plates 401 away from each other, the telescopic rods 404 are fixedly connected to the support plate 101, a spring 405 is arranged outside the telescopic rods 404, two ends of the spring 405 are respectively fixedly connected to the support plate 101 and the movable plate 401, the second cylinder 407 is fixedly connected to the bottom surface of the movable plate 401, the transmission shaft of the second cylinder 407 is coaxially fixed with the second telescopic rod 4071, the bottom end of the second telescopic rod 4071 is fixedly connected to the second mounting frame 403, the fixed pressure roller 402 is movably mounted on the second mounting frame 403, The outer diameter of the bearing block 406 is larger than the outer diameter of the connecting column 601, and the bearing block 406 is made of rubber. In this embodiment, when the fixing mechanism 4 is working, the cylinder 407 drives the telescopic rod 4071 to move downward, thereby driving the fixed pressure roller 402 to move downward and fit closely with the edge of the paper box to fix the paper box. The axis of the connecting column 601 and the bearing block 406 matched therewith are on the same horizontal line. The bearing block 406 made of rubber can protect the connecting column 601 and improve the service life of the connecting column 601. After the connecting column 601 contacts the bearing block 406, the connecting column 601 drives the bearing block 406 and the movable plate 401 to move so that the telescopic rod 404 and the spring 405 contract, and the movable plate 401 takes the fixed pressure roller 402 away from the paper box, so that the flattening mechanism 3 flattens the edge of the paper box.

[0029] Among them, two telescopic rods 3 408 are arranged on both sides of the cylinder 2 407, and the telescopic rods 3 408 are arranged perpendicular to the horizontal plane. The two ends of the telescopic rods 3 408 are respectively fixedly connected to the movable plate 401 and the mounting frame 2 403. The arrangement of the telescopic rods 3 408 in this embodiment improves the overall stability of the fixing mechanism 4, prevents the telescopic rods 2 4071 from bending, and improves the service life of the fixing mechanism 4.

[0030] Among them, the flattening mechanism 3 includes a cylinder 301, a mounting frame 302 and a flattening roller 303. The cylinder 301 is fixedly connected to the bottom surface of the sliding plate 6. The transmission shaft of the cylinder 301 is coaxially fixed with the telescopic rod 3011. The mounting frame 302 is fixedly connected to the bottom end of the telescopic rod 3011. The flattening roller 303 is movably mounted on the mounting frame 302. In this embodiment, the flattening roller 303 flattens the paper box. The cylinder 301 drives the telescopic rod 3011 to extend so that the flattening roller 303 contacts the surface of the paper box. The sliding plate 6 moves to drive the flattening roller 303 to move and flatten the paper box.

[0031] Among them, two fixed plates 201 are fixedly set on the bottom surface of the top plate 2, the screw 501 is set between the fixed plates 201 and one end of the screw 501 is connected to the side bearing of a fixed plate 201, and guide rods 502 are set on both sides of the screw 501. The guide rods 502 are fixedly connected to the fixed plates 201, and the fixed plate 201 passes through the sliding plate 6 and is slidably connected to the sliding plate 6. In this embodiment, the guide rod 502 guides the sliding plate 6 and limits the moving direction of the sliding plate 6. At the same time, it also supports the sliding plate 6 to prevent the screw 501 from bending.

[0032] It can be understood that first, the edge of the paper box is fixed by the fixing mechanism 4 to prevent the paper box from shifting during the flattening process, and then the motor 5 drives the screw 501 to rotate to move the sliding plate 6 and bring the flattening roller 303 to flatten the entire paper box. When the flattening roller 303 moves to the edge of the paper box, the connecting column 601 contacts the fixing mechanism 4 and drives the fixing mechanism 4 to leave the paper box, so that the flattening roller 303 flattens the edge of the paper box.

[0033] A specific application of this embodiment is: a paper box is placed on the processing table 1, and the cylinder 2 407 is started to drive the fixed pressure roller 402 to descend and press the edge of the paper box to fix the paper box, and then the cylinder 1 301 is driven to make the flattening roller 303 closely contact with the surface of the paper box, and then the motor 5 is driven, and the motor 5 drives the screw 501 to rotate, and the rotation of the screw 501 drives the sliding plate 6 to move, and the movement of the sliding plate 6 drives the flattening roller 303 to move to flatten the paper box, and the moving plate 401 drives the flattening roller 303 to move to the fixed pressure roller 402 When approaching, the connecting column 601 contacts the supporting block 406 and drives the supporting block 406 and the movable plate 401 to move, so that the telescopic rod four 404 and the spring 405 shrink, and the movable plate 401 drives the fixed pressure roller 402 to gradually leave the carton, and the flattening roller 303 flattens the edge of the carton. After the flattening work is completed, the motor 5 drives the screw 501 to reverse, so that the sliding plate 6 moves in the opposite direction. Under the action of the spring 405, the movable plate 401 brings the fixed pressure roller 402 gradually close to the carton and contacts the carton again to fix the carton.
