By adopting the scheme, the simple work flow of the flattening processing device for processing the bamboo material is as follows:
the bamboo strip blanks 8 are conveyed from the conveying surface of the feeding conveying unit 1 to the processing station corresponding to the quantitative feeding unit 2, then the bamboo strip blanks 8 are separated one by the material guide plates 24 of the quantitative feeding unit 2 and are conveyed to the output end of the feeding conveying unit 1 one by one, the bamboo strip blanks 8 conveyed from the output end of the feeding conveying unit 1 enter between the positioning rollers 32 of the feeding shaping unit 3 and the tail end of the output end of the feeding conveying unit 1, meanwhile, the guide rollers 34 are contacted with the bamboo strip blanks 8 under the action of the springs 38, at the moment, the bamboo strip blanks 8 rotate along with the action of friction force because the guide rollers 34 keep rotating (anticlockwise rotating in the drawing), and because the outer surfaces of the guide rollers 34 are sleeved with rubber sleeves 341, the bamboo strip blanks 8 are subjected to a turning force along the direction approaching to the positioning rollers 32 due to the friction of the rubber sleeves, however, since the outer wall of the bamboo strip blank 8 is arc-shaped, when the arc area of the outer wall contacts the surface of the positioning roller, a state similar to in-situ slipping is presented, and when the open end 81 of the bamboo strip blank 8 contacts the surface of the positioning roller 32, an instantaneous supporting point is formed, which causes the bamboo strip blank 8 to turn over around the instantaneous supporting point, so as to be buckled on the positioning roller 32, in addition, the shaping plate 33 also plays a role of positioning constraint, so as to prevent the bamboo strip blank 8 from slipping or misplacing from the surface of the positioning roller 32 due to inertia when turning over, at this time, the lifting mechanism 394 drives the positioning roller 32 together with the bamboo strip blank 8 buckled on the positioning roller to descend to the material transfer unit 4, and then the bamboo strip blank 8 is supported by the transfer seat 41 of the material transfer unit 4, at this time, the controller controls the third cylinder 63 of the material transfer unit 6 corresponding to the material transfer unit 4 to act again, a push rod 64 connected to a piston rod of a third oil cylinder 63 moves to one side of one end of the bamboo batten blank 8 (specifically, one side of the end far away from the flattening processing unit 5), then a second oil cylinder 61 acts and extends out to drive the push rod 64 to push the bamboo batten blank to enter an unfolding seat 52 of the flattening processing unit 5, then a lifting mechanism 394 drives a positioning roller 32 to reset, the third oil cylinder 63 and the second oil cylinder 61 reset in sequence, and then a first oil cylinder 53 of the flattening processing unit 5 acts to drive a pressing plate 531 to press down to a preset position to realize the pressing-down expansion of the bamboo batten blank 8, and the upper end surfaces of the unfolding seats 52 except the last one are of arc structures, so that the arc structures can guide the expansion of two sides of the opening end of the bamboo batten blank 8; after the flattening treatment is finished in one flattening treatment unit 5, the flattened bamboo strip blank 8 is pushed to the next flattening treatment unit through a material pushing unit 6 of the flattening treatment unit 5 for further flattening treatment until the bamboo strip is flattened into flattened bamboo strips, and the flattened bamboo strips are output through a blanking transmission unit 7; when the flattening treatment unit 5 is used for treatment, the input of the heating steam source 9 and the air flow guide of the negative pressure device 94 can be kept, so that the temperature and humidity environment inside the treatment box 51 of the flattening treatment unit 5 can be kept, and the bamboo is subjected to flattening expansion treatment at a better softening temperature and softening treatment humidity in the processing process.

s03, vertically downwards arranging the axial opening end of the bamboo blank B at 80-95 ℃, applying pressure to the bamboo blank B in the vertical direction, simultaneously, conducting expansion guide to two sides of the axial opening end of the bamboo blank B, stopping applying vertical pressure when the bamboo blank B is expanded to a preset opening degree, and then keeping for 3-5 min to obtain a bamboo blank C8-1;
s04, vertically downwards arranging the axial opening end of the bamboo blank C at 70-85 ℃, applying pressure to the bamboo blank C in the vertical direction, simultaneously, conducting expansion guide to two sides of the axial opening end of the bamboo blank C, stopping applying vertical pressure when the bamboo blank C is expanded to a preset opening degree, and then keeping for 3-5 min to obtain a bamboo blank D8-2;
