[0037] The utility model proposes a kind of paperboard pressing device 100, such as Figures 1 to 6As shown, the paper pressing device 100 comprises: a pressing support beam 1, a plurality of pressing mechanisms 20 arranged below the pressing support beam 1, each of the pressing mechanisms 20 comprises a pressing piece 24, a support adjusting structure 30, and a pressing plate 2, the first end of the support adjusting structure 30 is rotationally connected with the pressing plate 2, and the second end of the support adjusting structure 30 is rotationally connected with the pressing support beam 1, the pressing piece 24 is arranged between the pressing support beam 1 and the pressing plate 2, and the lower end of the pressing piece 24 abuts against the pressing plate 2. In this embodiment, the pressing piece 24 is installed on the pressing support beam 1.

[0038] Specifically, the lower part of the pressing support beam 1 is used to hang the plurality of pressing mechanisms 20, when the pressing support beam 1 moves downward, the plurality of pressing plates 2 of the pressing mechanisms 20 can be pushed to move downward to press the multi-layer paper; the number of the pressing plates 2 corresponds to the number of the support adjusting structures 30 and the pressing pieces 24, the support adjusting structure 30 is used to hang the pressing plate 2, and the pressing piece 24 is used to apply pressure to the pressing plate 2 to make the pressing plate 2 press the multi-layer paper. When the multi-layer paper is transported to the lower part of the pressing support beam 1 by the moving conveying belt 7, the width of the multi-layer paper is less than the total width of the plurality of pressing plates 2, the support adjusting structure 30 can be rotated to adjust the pressing plates 2 at both ends of the pressing support beam 1 to move upward, the lifted pressing plates 2 are in a standby state, and the pressing plates 2 that are not lifted apply pressure through the pressing piece 24, so that the sum of the widths of the plurality of pressing plates 2 corresponds to the width of the multi-layer paper, a specified relative number of the pressing plates 2 press the multi-layer paper, and the paper pressing device 100 can press the multi-layer paper with different widths.

[0039] Preferably, as shown in Figure 1 , Figure 2 , Figure 9 In the length direction of the pressing support beam 1, the height of the pressing support beam 1 gradually decreases from the middle part to the end part of the pressing support beam 1. Specifically, the middle part of the pressing support beam 1 is higher, and the two ends are lower, which can disperse the stress and improve the carrying capacity of the pressing support beam 1.

[0040] Preferably, as shown in Figure 9 The pressing support beam 1 is in an arch shape, and the arc side of the pressing support beam 1 is arranged away from the pressing mechanism 20. Specifically, the pressing support beam 1 is in an arch shape, which can convert the vertical load into axial pressure along the arch body, rather than the bending stress of the flat beam, thereby greatly reducing the internal shear force and bending moment; under the same span, the carrying capacity of the arch-shaped pressing support beam 1 is improved by 30%-50% compared with the flat pressing support beam 1.

[0041] Further, as shown in Figure 1 , Figure 2 , Figure 6As shown, the pressing support beam 1 comprises a support beam 12 and two pressing beams 11, which are installed on both sides of the support beam 12 and have an arch shape, so as to improve the overall stability and load capacity of the pressing support beam 1.

[0043] In some embodiments, as shown in Figure 7 the pressing plate 2 has a trapezoidal shape, one end of the pressing plate 2 has a narrow side 212, and the other end has a wide side 211, the two adjacent pressing plates 2 are at the same height, and the narrow side 212 of one pressing plate 2 is protruded relative to the wide side 211 of the other pressing plate 2. Specifically, the distance between the narrow side 212 of one pressing plate 2 and the pressing support beam 1 is greater than the distance between the other pressing plate 2 and the pressing support beam 1, so that no matter the moving conveyor belt 7 moves left or right, the narrow side 212 of the pressing plate 2 is always in contact with the moving conveyor belt 7; the pressing plate 2 has an isosceles trapezoidal shape, the included angle 213 between the narrow side 212 and the oblique side is obtuse, and when the narrow side 212 is in contact with the moving conveyor belt 7, the lower end surface of the two top corners of the narrow side 212 is large, which can reduce the instantaneous stress of the contact between the pressing plate 2 and the moving conveyor belt 7 and further avoid the abrasion of the moving conveyor belt 7 by the pressing plate 2.

[0044] Preferably, as shown in Figure 7 the two adjacent pressing plates 2 are staggered at the same height, and the narrow side 212 of one pressing plate 2 and the wide side 211 of the other pressing plate 2 are arranged on the same side of the pressing support beam 1. Specifically, the pressing plate 2 arranged in this way can make the narrow sides 212 of the plurality of pressing plates 2 on any side of the pressing support beam 1 away from the pressing support beam 1, the narrow sides 212 of the pressing plates 2 are always in contact with the moving conveyor belt 7, and the plurality of pressing plates 2 are regularly and neatly distributed below the pressing support beam 1.

The moving direction of the driving rod 62 intersects with the length direction of the adjusting rod 63. Specifically, the driving member 61 is a pneumatic cylinder. The driving member 61 pushes the driving rod 62 to move. The driving rod 62 pushes the adjusting rod 63 to rotate. The adjusting rod 63 drives the first swing assembly 4 or the second swing assembly 5 to rotate, thereby further lifting the pressing plate 2.

The adjusting bolt 64 is screwed with the pressing support beam 1. The adjusting bolt 64 is rotated to abut against the adjusting rod 63. The first rotating shaft 42 is adjusted to rotate, so that the pressing plate 2 can be slightly lifted upward, thereby playing a certain adjusting role.

[0051] In some embodiments, as shown in Figures 4 to 6 As shown, the first swing assembly 4 comprises the first rotating shaft 42, the second rotating shaft 44, the two first swing arms 43, and the two first support blocks 41.
