At the same time, the edge of the cardboard can be pressed to prevent warping. By arranging a linkage column 9 on the trimming movable frame 402, the two edge pressing frames 601 can be linked to move, which can not only ensure that the feeding is not hindered, but also realize the squeezing of the cardboard. The edge pressing linkage groove 702 is slidably connected to the linkage column 9 in real time. During the movement of the trimming movable frame 402, the front section of the edge pressing linkage groove 702 is a straight groove. At this time, the edge pressing device 6 is located on both outer sides. Figure 1 , during this process, the adsorption device 3 is also in the process of being adsorbed from the material box 201 to the cardboard and rotating to the left to reset. Therefore, at this time, the edge pressing device 6 is located on both sides and will not affect the feeding of the adsorption device 3.

The linkage column 9 continues to move with the trimming movable frame 402, passing through the last section of the inclined groove on the edge pressing linkage groove 702. At this time, the cardboard cutting has been completed. Driven by the linkage column 9, the edge pressing frame 601 will be driven to move to both sides and reset through the edge pressing linkage groove 702.

The structure is simple and the linkage is strong. The arranged edge pressing device 6 effectively improves the cutting processing accuracy and makes the cardboard cutting edge more neat.

[0030] Specific usage and function of this embodiment: In the present invention, first, the staff only needs to place the cardboard on the push plate 202, and then the automatic loading can be realized through the operation of the driving part 4. Figure 1, when the trimming movable frame 402 on the driving part 4 is driven by the driving screw 403, the set flipping propulsion part 8 will be driven at the same time. During the process, when the trimming movable frame 402 moves to the left, when the trimming movable frame 402 is close to the left side, at this time, the rack 802 engages with the driving linkage gear 302, so that the linkage gear 302 drives the flipping in the direction of the feeding part 2. During the process, with the squeezing of the adsorption plate 301, the pushing plate 202 can automatically drop in height to facilitate the adsorption of the adsorption plate 301. Subsequently, the adsorption plate 301 can adsorb the cardboard. When the trimming movable frame 402 moves to the right for trimming and leveling, at this time, it will drive the rack 802 to flip to the left. The cardboard is driven to be placed on the support plate 101. The flattening part 5 can be automatically attached to the cardboard under the squeezing action of the spring, and the cardboard is effectively flattened to improve the production quality of the carton and reduce the defective rate. At the same time, the driving part 4 is also integrated with a cutting driving block 404. The two cutting driving blocks 404 can control the trimming length at the same time by rotating the bidirectional threaded rod 405. The two cutter bodies 4041 are responsible for real-time cutting. The linkage column 9 arranged on the trimming moving frame 402 can realize the linkage movement of the two edge pressing frames 601, which can not only ensure that the loading is not hindered, but also realize the squeezing of the cardboard. The edge pressing linkage groove 702 is arranged The internal real-time sliding connection linkage column 9, during the movement of the trimming movable frame 402, the front section of the edge pressing linkage groove 702 is a straight groove, and the edge pressing device 6 is located at the two outer sides. In this process, the adsorption device 3 is also adsorbed from the material box 201 to the cardboard and rotates to the left to reset. Therefore, at this time, the edge pressing device 6 is located at the two outer sides and will not affect the feeding of the adsorption device 3. Subsequently, the linkage column 9 continues to move with the trimming movable frame 402, passing through the first section of the inclined groove on the edge pressing linkage groove 702. During this process, the edge pressing frame 601 will be driven to move inward, so that the cardboard is squeezed and fixed through the edge pressing roller frame 602. In this process, the flattening part 5 and the cutter body 4041 are also engaged. During the leveling and cutting process, the linkage column 9 continues to move with the trimming movable frame 402, passing through the last section of the inclined groove on the edge pressing linkage groove 702. At this time, the cardboard has been cut, and driven by the linkage column 9, the edge pressing frame 601 will be driven to move to both sides and reset through the edge pressing linkage groove 702. At this time, the remaining cardboard after cutting can be separated from the edge pressing roller frame 602. Subsequently, the trimming movable frame 402 also moves to the far right, and the feeding screw 103 drives the propulsion bracket 102 to directly push the finely trimmed and leveled cardboard into the carton bending and forming machine, and the reciprocating work is used for feeding, and finally the use process of the cardboard leveling and feeding device for packaging box production is completed.

However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
