[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0041] Embodiment 1: Figure 1 As shown, the present application provides a cardboard flattening device, which is used in the factory flattening operation of cardboard to make the cardboard meet the factory requirements, and the device includes:

[0042] A workbench 1, which serves as a support for the entire device and is used to support various components. A conveying mechanism 11 is provided on the workbench 1. The conveying mechanism 11 is used to carry the cardboard to be leveled and convey the cardboard to realize assembly line operation. The conveying mechanism 11 has a feeding part and a discharging part. The conveying mechanism 11 includes a conveyor belt 111, which is provided on the workbench 1. The conveyor belt 111 is connected to a driving mechanism (not shown in the figure). The driving mechanism is used to provide power for the conveyor belt 111, and drive the cardboard to move from the direction of the feeding part to the direction of the discharging part, thereby realizing assembly line operation without manual intervention and improving production efficiency. In this embodiment, the driving mechanism can be a servo motor, or other devices that can move the conveyor belt 111, which is not limited in this embodiment;

[0043] It should be noted that a collecting device may be provided at the discharging portion of the conveying mechanism 11, and the collecting device is used to collect the flattened paperboards. In this embodiment, the collecting device is not limited, as long as it can collect the flattened paperboards.

[0044] like Figure 1As shown, in order to flatten the cardboard, a flattening mechanism 12 is further provided on the workbench 1. The flattening mechanism 12 is generally located above the conveying mechanism 11, so as to flatten the cardboard placed on the conveyor belt 111. The flattening mechanism 12 includes a driving motor 121, which is fixedly mounted on the workbench 1. At the same time, the output end of the driving motor 121 is fixedly connected to a roller shaft, and a flattening roller 122 is mounted on the roller shaft. Under the drive of the driving motor 121, the flattening roller 122 can rotate;

[0045] There is a gap between the leveling roller 122 and the conveyor belt 111, and the gap is used to accommodate the cardboard to be leveled. The surface of the leveling roller 122 is in direct contact with the surface of the cardboard, thereby achieving the leveling operation of the cardboard;

[0046] In order to flatten the cardboard to be flattened multiple times, so as to adapt to thicker cardboard, such as Figure 1 As shown, there are at least two groups of leveling mechanisms 12, and in the leveling mechanism 12 on the side close to the feeding part of the conveying mechanism 11, the installation height of the driving motor 121 is greater than that of the driving motor 121 on the side away from the feeding part of the conveying mechanism 11. Therefore, the leveling rollers 122 in the two groups of leveling mechanisms 12 will have different heights. Specifically, the leveling roller 122 on the side close to the feeding part is higher, so the distance between it and the conveyor belt 111 is larger, so as to adapt to the cardboard that has not been leveled, while the leveling roller 122 on the side away from the feeding part is lower in height, and the distance between it and the conveyor belt 111 is smaller, so as to adapt to further leveling the cardboard after preliminary leveling. When the thickness of the cardboard is large, the cardboard is gradually leveled by two groups of leveling mechanisms 12 with different heights, which can prevent the cardboard from being damaged by excessive leveling force, and realize the loss display operation, thereby improving production efficiency.

[0047] Embodiment 2: In the embodiment 1 of the present application, by setting the leveling mechanism 12 of different heights, the cardboard is gradually leveled. Since the driving motor 121 is directly fixed to the workbench 1, its height cannot be adjusted. When it is necessary to level different batches of different types of cardboard, it is necessary to replace the equipment, which not only increases the workload, but also leads to an increase in production costs. Therefore, the following improvements are made in this embodiment:

[0048] like Figure 2 As shown, the driving motor 121 is no longer directly fixed to the workbench 1, but is provided with an adjustment component 13, through which the height of the driving motor 121 is adjusted to adapt to different batches of paperboards with different thicknesses. The adjustment component 13 includes at least two fixed shafts 131, which are fixedly mounted on the workbench 1, and a mounting plate 132 is fixedly mounted on the fixed shaft 131, and the mounting plate 132 is vertically arranged, and the driving motor 121 is fixed on the mounting plate 132;

[0049] In order to adjust the height of the mounting plate 132, and then adjust the height of the driving motor 121, so that there are gaps of different sizes between the leveling roller 122 and the conveyor belt 111, a screw sleeve 133 is fixed on the side of the mounting plate 132 away from the driving motor 121, and a first rotating shaft 134 is arranged in the screw sleeve 133, and one end of the first rotating shaft 134 is connected to the bearing of the workbench 1, so that the first rotating shaft 134 can rotate, and a thread 135 is arranged at a height position close to the screw sleeve 133 on the first rotating shaft 134. When the first rotating shaft 134 is rotated, the screw sleeve 133 will cooperate with the thread 135 on the first rotating shaft 134, so as to move up and down along the thread 135, thereby driving the mounting plate 132 fixed with the screw sleeve 133 to move, and during the movement, the height of the driving motor 121 is changed to achieve the height adjustment of the leveling roller 122;

[0050] For ease of operation, a first handle 136 is fixed to the other end of the first rotating shaft 134, and the first rotating shaft 134 can be controlled to rotate by the first handle 136, thereby completing the above process;

[0051] like Figure 2 As shown, when there are two groups of leveling mechanisms 12, both groups of leveling mechanisms 12 are provided with adjustment components 13 of the same structure, and the leveling mechanisms 12 at different positions are adjusted respectively by the two groups of adjustment components 13, which will not be repeated in this embodiment.

[0052] Embodiment 3: Since the sizes of cardboards of different batches and models are different, when the length of the cardboard is long, in order to ensure the same leveling effect in each area, it is necessary to make each leveling mechanism 12 at the same height to prevent uneven leveling of the cardboard. Therefore, the following improvements are made on the basis of Embodiment 2:

[0053] like Figure 2-Figure 3 As shown, a support plate 137 is provided on the fixed shaft 131, and a plurality of fixed blocks 138 are provided on the support plate 137. A pair of connecting rods 139 are installed in the fixing blocks 138, and a spring 140 is sleeved on the pair of connecting rods 139. One end of the spring 140 is connected to the fixing block 138, and the other end is connected to a shaft seat 141. The shaft seat 141 is sleeved on the connecting rod 139 and supported by the spring 140.

[0054] like Figure 3As shown, a second rotating shaft 142 is provided in the shaft seat 141, and the second rotating shaft 142 is suitable for moving in the shaft seat 141, and a sliding groove 143 is provided on the first rotating shaft 134, and the second rotating shaft 142 passes through the sliding groove 143, and is suitable for moving up and down in the sliding groove 143, a first bevel gear 144 is fixedly installed on the first rotating shaft 134, and a second bevel gear 145 is fixedly installed on the second rotating shaft 142, and the first bevel gear 144 and the second bevel gear 145 can be controlled to mesh by controlling the height and sliding distance of the second rotating shaft 142. After the first bevel gear 144 and the second bevel gear 145 are meshed, the rotation control of the first rotating shaft 134 can be realized by rotating the second rotating shaft 142, thereby controlling the height of the leveling mechanism 12;

[0055] It should be noted that the slide slot 143 has enough space to allow the second rotating shaft 142 to rotate while driving the first rotating shaft 134 to rotate;

[0056] like Figure 2 As shown, when there are two groups of leveling mechanisms 12, the first rotating shafts 134 of the two groups of leveling mechanisms 12 are both provided with first bevel gears 144 of the same model and the same height, and the number of second bevel gears 145 is two. When the second rotating shaft 142 is adjusted, the two pairs of first bevel gears 144 are meshed with the second bevel gears 145 at the same time. By controlling the rotation of the second rotating shaft 142, the two groups of leveling mechanisms 12 can be synchronously controlled to prevent the two groups of leveling mechanisms 12 from being at different heights due to operating errors during the separate control process. When separate control is required, the second rotating shaft 142 can be controlled to separate the first bevel gear 144 from the second bevel gear 145, which is convenient for operation.

[0057] It should be noted that, under normal circumstances, the second rotating shaft 142 will be located at the top of the slide groove 143 under the action of the elastic force of the spring 140. During the adjustment process, the spring 140 will be compressed. When the first bevel gear 144 and the second bevel gear 145 are disengaged, the elastic force of the spring 140 will support the second rotating shaft 142 to return to the initial position without applying additional force to it.

[0058] For convenient control, a second handle 146 is disposed at one end of the second rotating shaft 142 , and a fixing pin 147 is disposed at the other end of the second rotating shaft 142 to prevent the second rotating shaft 142 from being separated from the shaft seat 141 .

[0059] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
