Among them, the connection manner between the first pressure wheel 261 and the first unfolding roller 260, and the connection manner between the second unfolding roller 270 and the second pressure wheel 271 can be integrally formed or key-connected.

[0043] Please refer to Figure 3 , which is a schematic structural diagram of the material shaping machine 900 shown in an embodiment of the present application. The sizes of the first channels 280 in the multiple pressure roller units 200 change regularly. The axes of the first unfolding rollers 260 in the multiple pressure roller units 200 are parallel to each other and can be located in different planes. The axes of the second unfolding rollers 270 in the multiple pressure roller units 200 are parallel to each other and are all located on the second plane Q2. The direction perpendicular to the second plane Q2 downward is called the first direction D1, and the direction perpendicular to the second plane Q2 upward is called the second direction D2.

[0044] The multiple pressure roller units 200 are sequentially divided into a flattening group 400, a gradually flattening group 500, a straightening group 600, and a reverse bending group 700 along a straight line direction. The gradually flattening group 500 is sequentially divided into a front gradually flattening group 510 and a rear gradually flattening group 520 along a straight line direction.

[0045] In this embodiment, by making the material to be processed after cooking and softening enter the first channels 280 of each pressure roller unit 200 and sequentially passing through the shaping of the flattening group 400, the gradually flattening group 500, the straightening group 600, and the reverse bending group 700, the material to be processed can be unfolded and shaped into a relatively flat plate-like structure without large cracks affecting the quality.

[0046] In the flattening group 400, and in each pressure roller unit 200, the first surface 261a is a curved surface protruding outward, and the second surface 271a is a curved surface recessed inward; and the size of the first channel 280 in each pressure roller unit 200 remains unchanged and is a downward concave arc-shaped structure for bending and unfolding the material to be processed in the first direction D1.

[0047] The flattening group 400 further includes a plurality of node removing devices 800. The node removing devices 800 are arranged between adjacent two pressure roller units 200. The node removing device 800 includes a cutting tool 815 (Please refer to Figure 5) It is used to cut the protruding parts of the material to be processed, such as the bamboo joints of bamboo, so as to improve the flattening quality.

[0048] The multiple node-removing devices 800 include multiple upper-node-removing devices 840 and multiple lower-node-removing devices 850. In the upper-node-removing device 840, the cutting tool 815 (please refer to Figure 5 ) is a convex arc-shaped knife, located above the first channel 280, and is used to cut the protruding parts on the upper surface of the material to be processed; in the lower-node-removing device 850, the cutting tool 815 is a concave arc-shaped knife, located below the first channel 280, and is used to cut the protruding parts on the lower surface of the material to be processed.

[0049] In one embodiment, in the flattening group 400, in each pressing roller unit 200, the parameters such as the size and shape of the first pressing wheel 261 and the second pressing wheel 271 remain unchanged. The first pressing wheel 261 is in the shape of a rugby ball, and its first surface 261a is a circular arc-shaped convex curved surface with a radius of 80 mm. The second pressing wheel 271 is in a shape similar to a dumbbell, and its second surface 271a is a circular arc-shaped concave curved surface with a radius of 90 mm. In each upper-node-removing device 840, the cutting tool 815 is in the shape of a rugby ball, and its outer surface is an arc-shaped convex curved surface cutting edge with a radius of 80 mm. In each lower-node-removing device 850, the cutting tool 815 is in a shape similar to a dumbbell, and its outer surface is an arc-shaped concave curved surface cutting edge with a radius of 90 mm.

[0050] Among them, in the flattening group 400, there are 32 pressing roller units 200, and their arrangement can be: 4 pressing roller units 200, 1 upper-node-removing device 840, 2 pressing roller units 200, 1 lower-node-removing device 850, 2 pressing roller units 200, 1 lower-node-removing device 850, 2 pressing roller units 200, 1 upper-node-removing device 840, 2 pressing roller units 200, 1 lower-node-removing device 850, 2 pressing roller units 200, 1 upper-node-removing device 840, 2 pressing roller units 200.

[0051] During an operation process, the material to be processed after being softened by steaming enters the flattening group 400, passes through multiple pressing roller units 200, is initially shaped, bends and unfolds in the first direction D1, and at the same time, the protruding parts on the material to be processed are removed by multiple node-removing devices 800 to improve the effect after shaping.

[0052] In the gradual flattening group 500, in each pressing roller unit 200, the parameters such as the size and shape of the first pressing wheel 261 and the second pressing wheel 271 gradually change, so that the size of the first channel 280 gradually changes and decreases, and is used to gradually flatten the material to be processed.

The parameters such as the size and shape of the first pressure wheel 261 and the second pressure wheel 271 in two pressure roller units 200 within each small group are the same.

[0056] For example, in the first small group, the first pressure wheel 261 is in the shape of a rugby ball, and its first surface 261a is a circular arc convex curved surface with a radius of 100 mm. The second pressure wheel 271 is in a shape similar to a dumbbell, and its second surface 271a is a circular arc concave curved surface with a radius of 110 mm. In the second small group, the first pressure wheel 261 is in the shape of a rugby ball, and its first surface 261a is a circular arc convex curved surface with a radius of 120 mm.

In the third small group, the first pressure wheel 261 is in the shape of a rugby ball, and its first surface 261a is a circular arc convex curved surface with a radius of 140 mm. The second pressure wheel 271 is in a shape similar to a dumbbell, and its second surface 271a is a circular arc concave curved surface with a radius of 210 mm.

[0057] In the straightening group 600, the size of the first channel 280 remains unchanged and it has a straight structure for flattening the material to be processed. The first surface 261a and the second surface 271a in each pressure roller unit 200 are both cylindrical curved surfaces.

The first pressure wheel 261 and the second pressure wheel 271 are both cylindrical, such that the cross-section of the first channel 280 is rectangular.

[0058] In the reverse bending group 700, the size of the first channel 280 remains unchanged, which is used to bend and unfold the material to be processed in the second direction D2, and the second direction D2 is set opposite to the first direction D1. The first surface 261a in each pressure roller unit 200 is a curved surface that bulges outwards, and the second surface 271a in each pressure roller unit 200 is a curved surface that bulges outwards.

[0059] In one embodiment, in the reverse bending group 700, in each pressing roller unit 200, parameters such as the size and shape of the first pressing wheel 261 and the second pressing wheel 271 remain unchanged. The first pressing wheel 261 is in the shape of a rugby ball, and its first surface 261a is a circular arc convex curved surface with a radius of 140 mm. The second pressing wheel 271 is in the shape of a rugby ball, and its first surface 261a is a circular arc convex curved surface with a radius of 140 mm. Among them, in the flattening group 400, there are 14 pressing roller units 200.

The setting of the reverse bending device can apply a reverse bending force to the material to be processed to prevent it from returning to its original state and improve the flattening quality.
