[0026] In the embodiment, one side of the inner cavity of the device frame 1 is provided with a guide assembly, the guide assembly is three groups, and each group of guide assemblies is located on one side of one lower pressing plate 8, each group of guide assemblies includes a guide plate 9 fixedly connected with the inner wall of one side of the device frame 1, the guide plate 9 is fixedly connected with a guide column 10 on the side overlapping with the device frame 1, the outer side of the guide block 702 is matched with the inner side of the guide plate 9, the guide groove 703 is provided on one side of the guide block 702, the guide groove 703 is matched with the guide column 10, when the driving motor 2 starts, the guide block 702 slides along the inner wall of the guide plate 9 stably, at the same time, the guide column 10 is inserted into the guide groove 703, which plays a further stabilizing and guiding role, ensuring that the upper pressing plate 7 will not deviate or shake during the flattening process, after completing the flattening of the carton paperboard on one lower pressing plate 8, the upper pressing plate 7 continues to move to the upper side of the next lower pressing plate 8, in this process, the matching relationship between the guide block 702, the guide plate 9 and the guide column 10 and the guide groove 703 remains unchanged, ensuring that the upper pressing plate 7 can accurately align each lower pressing plate 8 for flattening operation, when the upper pressing plate 7 moves to the rightmost side and completes the flattening operation, it can return to the starting position on the leftmost side, preparing for the next round of flattening operation, throughout the whole cycle, the guide assembly always ensures the stability and accuracy of the upper pressing plate 7;

[0027] The design of the guide assembly greatly improves the stability of the upper pressing plate 7 during the flattening process. Through the cooperation of the guide plate 9 and the guide column 10, the upper pressing plate 7 can move smoothly along the predetermined trajectory, avoiding the problem of uneven flattening caused by deviation or shaking. The engagement of the guide block 702 with the guide plate 9 and the cooperation of the guide groove 703 with the guide column 10 ensure that the upper pressing plate 7 can accurately align each lower pressing plate 8 for flattening operation. This improves the accuracy of flattening and ensures the quality of carton paperboard.

[0028] In this embodiment, the top of the side block 701 and the guide block 702 is provided with a buffer part 704, which includes a connecting part 7041 connected to the side block 701 and the guide block 702. The bottom of the connecting part 7041 is provided with an arc-shaped buffer 7042, and the bottom of the arc-shaped buffer 7042 is provided with a contact part 7043. The buffer part 704 is stably connected to the side block 701 and the guide block 702 through the connecting part 7041. The arc-shaped buffer 7042 is in a natural state, and the contact part 7043 is located at the bottom of the arc-shaped buffer 7042, ready for buffer contact. When the upper pressing plate 7 starts to contact other parts of the device frame 1 during the flattening process, the buffer part 704 on the side block 701 and the guide block 702 first contacts the contact surface. The contact part 7043, as the front end of the buffer part 704, first bears the impact force and starts to compress the arc-shaped buffer 7042. As the contact part 7043 compresses the arc-shaped buffer 7042, the arc-shaped buffer 7042 starts to play its buffering role, absorbing and dispersing the impact force. The arc-shaped design makes the buffering process more stable, reducing the damage to the upper pressing plate 7 and the entire device. After completing the flattening operation, the upper pressing plate 7 starts to return to its initial position. At this time, the arc-shaped buffer 7042 gradually recovers its original shape, and the contact part 7043 also returns to its initial position, ready for the next buffer contact. The design of the buffer part 704 effectively improves the buffering effect of the device. Through the compression and recovery of the arc-shaped buffer 7042, the impact force can be absorbed and dispersed, reducing the damage to the upper pressing plate 7 and the entire device. The presence of the buffer part 704 makes the upper pressing plate 7 more stable during the flattening process. Even if it encounters a larger impact force, the buffer part 704 can effectively buffer the impact force, preventing the upper pressing plate 7 from deviating or shaking. The presence of the buffer part 704 enables the upper pressing plate 7 to contact the carton paperboard more smoothly during the flattening process, avoiding the problem of uneven flattening caused by excessive impact force. This improves the quality of flattening and ensures the quality of carton paperboard.

[0029] The working principle and usage process of this utility model are as follows: Before the device is started, the upper pressure plate 7 is located above the leftmost lower pressure plate 8 and is in a raised state. Cardboard boxes to be flattened are placed on the three lower pressure plates 8 respectively. The drive motor 2 is started, and its output shaft drives the drive screw 3 to rotate. Since the transmission plate 4 is threadedly connected to the drive screw 3, the transmission plate 4 will move along the axial direction of the drive screw 3. At the same time, the adjusting plate 5 is fixedly connected to the transmission plate 4 and slides within the adjusting groove 101. The guide protrusion 102 ensures that the adjusting plate 5 moves smoothly without deviation. As the transmission plate 4 moves, the hydraulic rod 6 drives the upper pressure plate 7 to gradually descend until it contacts the cardboard box on the leftmost lower pressure plate 8 and applies pressure. Sufficient pressure is applied to flatten the cardboard. After the cardboard is flattened, the hydraulic rod 6 rises, causing the upper pressure plate 7 to detach from the cardboard. At this time, the drive motor 2 continues to work, driving the upper pressure plate 7 to move to the right above the next lower pressure plate 8. The above steps are repeated, and the upper pressure plate 7 flattens the cardboard on each lower pressure plate 8 in turn. While flattening one cardboard, the next cardboard can be placed on the newly vacated lower pressure plate 8, realizing a continuous feeding, flattening, and unloading process. When the cardboard on the rightmost lower pressure plate 8 is flattened, the upper pressure plate 7 can return to the leftmost side to start a new round of flattening, forming a cycle. When the drive motor 2 starts, it drives the upper pressure plate 7 to open... At the start of the flattening operation, the guide block 702 slides smoothly along the inner wall of the guide plate 9. Simultaneously, the guide post 10 inserts into the guide groove 703, providing further stability and guidance to ensure that the upper pressure plate 7 does not shift or wobble during the flattening process. After flattening the cardboard on one lower pressure plate 8, the upper pressure plate 7 continues to move above the next lower pressure plate 8. Throughout this process, the cooperation between the guide block 702 and the guide plate 9, and between the guide post 10 and the guide groove 703, remains constant, ensuring that the upper pressure plate 7 can accurately align with each lower pressure plate 8 for the flattening operation. When the upper pressure plate 7 moves to the far right and completes the flattening operation, it can return to the far left starting position, ready for the next operation. During the entire cycle of the flattening operation, the guiding components ensure the stability and accuracy of the upper pressure plate 7. When the upper pressure plate 7 begins to contact other parts of the device frame 1 during the flattening process, the buffer parts 704 on the side block 701 and the guide block 702 first come into contact with the contact surface. The contact part 7043, as the foremost part of the buffer part 704, first bears the impact force and begins to compress the arc-shaped buffer 7042. As the contact part 7043 compresses the arc-shaped buffer 7042, the arc-shaped buffer 7042 begins to play its buffering role, absorbing and dispersing the impact force. The arc-shaped design makes the buffering process smoother and reduces the damage of the impact to the upper pressure plate 7 and the entire device.
