Problems solved by technology

In this method, the expansion of the inner wall of the bamboo is actually the width of the grooves pressed by the convex teeth of the inner roller on the inner wall of the bamboo or the further deformation of the grooves, that is to say, it is the transformation of large cracks in the original bamboo. Because of the large difference between t

Embodiment Construction

[0024] Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the present invention is described in detail, selects the bamboo of more than 3 years of raw bamboo diameter in 30-60MM and the small diameter miscellaneous bamboo and industrial waste bamboo such as early bamboo, thunder bamboo as raw material. Fresh bamboo can be used for 3-12 months. The width of the pressing machine is cut into 2500MM bamboo segments, and the bamboo segments are notched, then softened by microwave, and then flattened. Under the combined action of the block 205 and the Oldham coupling 209, the raised steel nails 206 on the upper roller are inserted into the arc-shaped original bamboo 207, and the power is transmitted to the Oldham coupling 209 and the upper roller 208 through the sprocket 210 to drive the upper roller. 208 scroll. During rolling, the arc-shaped original bamboo 207 is pressed with a large number of artificially induced cracking holes by steel nails 206. The shape of the steel nails...

Abstract

The present invention discloses process and apparatus for flattening arc bamboo sheet. During flattening arc bamboo sheet, radial force is applied while dispersed crack-preventing holes are formed in the yellow layer of the arc bamboo sheet. The process of flattening arc bamboo sheet includes the first heating to soften bamboo material, and the subsequent flattening. The apparatus for flattening arc bamboo sheet includes one or several pairs of axially parallel rolls, and each roll pair includes one smooth roll and one nailed roll with dispersed lugs in the surface. The present invention has the advantages of less reduction of the strength of bamboo material, high utilization rate of bamboo resource and no cracking caused by flattening.

Description

technical field [0001] The invention relates to the field of bamboo processing, in particular to a bamboo flattening step in the bamboo processing process and a technique for flattening the bamboo with green bamboo spring leaves by applying the flattening step and a flattening device thereof. Background technique [0002] my country is located in the center of bamboo distribution in the world, and the area of ​​bamboo forest ranks first in the world. Because of its special hollow structure, bamboo has a large difference in inner and outer diameters. Therefore, in the process of processing, especially during flattening, smooth rollers located inside and outside the bamboo are generally used for flattening. When applying force to flatten the bamboo, the inner perimeter should be pulled to be the same as the outer perimeter, and the inner surface will inevitably undergo large deformation and breakage. In the Chinese Patent Application No. 03155410.5, a flattening method is discl...
