By adopting the scheme, the simple work flow of the flattening processing device for processing the bamboo material is as follows:
the bamboo strip blank 8 is 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 blank 8 is separated one by the material guide plate 24 of the quantitative feeding unit 2 and is conveyed to the output end of the feeding conveying unit 1 one by one, the bamboo strip blank 8 conveyed from the output end of the feeding conveying unit 1 enters between the positioning roller 32 of the feeding shaping unit 3 and the end of the output end of the feeding conveying unit 1, meanwhile, the guide roller 34 is contacted with the bamboo strip blank 8 due to the action of the spring 38, at this time, the bamboo strip blank 8 rotates along with the action of friction force due to the rotation of the guide roller 34 (anticlockwise rotation shown in the figure), and the rubber sleeve 341 is sleeved on the outer surface of the guide roller 34, therefore, the bamboo strip blank 8 is rotated and simultaneously receives a turning force along the direction close to the positioning roller 32 due to the friction of the rubber sleeve, 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 the material pushing unit 6 of the flattening treatment unit 5 for further flattening treatment until the flattened bamboo strip is finally flattened and output through the 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.
Based on the above technical solution, in combination with the schematic state change diagram of the bamboo cane blank in fig. 12, the present solution further provides a bamboo flattening processing method, which includes: cutting off the bamboo strip blank 8, axially opening, removing inner and outer joints and softening to obtain a bamboo blank, sequentially performing primary pressure application expansion treatment, secondary pressure application expansion treatment, tertiary pressure application expansion treatment and pressure application flattening treatment on the bamboo blank to flatten the bamboo blank, and performing pressure setting and air drying treatment on the bamboo blank until the water content is lower than 10% to obtain the flattened bamboo strip.

s03, vertically downwards arranging an axial opening end of a bamboo blank B at 80-95 ℃, applying pressure to the bamboo blank B in the vertical direction, simultaneously performing expansion guide on 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 maintaining for 3-5 min to obtain a bamboo blank C8-1;
s04, vertically downwards arranging an axial opening end of the bamboo blank C at 70-85 ℃, applying pressure to the bamboo blank C in the vertical direction, simultaneously, expanding and guiding 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 maintaining for 3-5 min to obtain a bamboo blank D8-2;
s05, vertically downwards arranging an axial opening end of a bamboo blank D at the temperature of 60-75 ℃, applying pressure to the bamboo blank D in the vertical direction, simultaneously, conducting expansion guide to two sides of the axial opening end of the bamboo blank D, stopping applying vertical pressure when the bamboo blank D is expanded to a preset opening degree, and then maintaining for 3-5 min to obtain a bamboo blank E8-3;

s07, pressurizing and shaping the bamboo blank F, and meanwhile, drying the bamboo blank F in an air drying and drying mode until the water content is lower than 10% to obtain flattened bamboo strips.
