Example 3
The method for lengthening the bamboo strips provided by the embodiment comprises the following steps:
s01: the bamboo strips are processed into regular bamboo strips, the water content of the bamboo strips is preferably 15%, the bamboo age is preferably 5 years, the length is preferably 600mm, the width is preferably 90mm, and the thickness is preferably 10mm.
S02: and (3) milling the two ends of the bamboo strip obtained in the step (S01) into a round buckle and a round buckle groove corresponding to the round buckle, wherein the large semicircular angle is preferably 220 degrees, and the vertical distance between the longitudinal convex edge of the round buckle and the root of the buckle is preferably 2mm.
S03 (bamboo strip sizing): and (3) gluing buckles and buckle grooves at two ends of the bamboo strips obtained in the step S02, wherein the gluing mode is glue spraying.
S04: and (3) longitudinally arranging the glued bamboo strips obtained in the step S03 according to the opposite positions of the round buckling ends and the round buckling groove ends.
S05: fixing the bamboo strips arranged in the step S04 at the forefront end, pushing the next bamboo strip so that the round buckles of the two bamboo strips are pushed into the round buckle grooves 4, and finally obtaining the lengthening bamboo strip with the length of 1200mm, the width of 90mm and the thickness of 10mm.
In summary, the special-shaped buckle connection is used to replace the common finger joint lengthening, the elastic-plastic property and toughness of the bamboo strips are utilized to control the width of the buckle and the buckle groove from the edges of the bamboo strips, the buckle enters the buckle groove to avoid damaging the bamboo strips, the connection strength of the connection part can be increased, the effect that the connection part is not easy to misplace and separate is achieved, the plastic film bundling and fixing procedure in the traditional finger joint process is omitted, the labor force is reduced, the continuity is improved, and the processing cost is reduced; the invention also produces the bamboo laminate with infinite length and the bamboo integrated material with infinite length respectively by the flat pressing and lengthening technology and the side pressing and lengthening technology.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and additions may be made to those skilled in the art without departing from the method of the present invention, which modifications and additions are also to be considered as within the scope of the present invention.
