Unit arc bamboo splint flattening and shaping method

Abstract

The invention discloses a unit arc bamboo splint flattening and shaping method. The method comprises the following steps of: removing internal and external joints after splitting moso bamboo at a fixed length to obtain a unit arc bamboo splint; softening the unit arc bamboo splint, wherein the unit arc bamboo splint is first softened to 90-110 degrees in a softening treatment pool for 20-22 hours; flattening the unit arc bamboo splint in a segmental way; feeding the unit bamboo splint in a treatment box with constant temperature of 20-40 degrees by using upper and lower press rolls; applying a certain pressure to the unit bamboo splint by using the upper and lower press rolls in the feeding process so as to flatten the unit bamboo splint; spraying cold water to the flattened unit bamboo splint so as to carry out cold treatment and shaping so that the overall dimension of the bamboo splint is stable; and finally, thickening and trimming the unit bamboo splint to obtain a bamboo splint with desired size. The unit arc bamboo splint flattening and shaping method disclosed by the invention has the advantages of simplified operation process and high working efficiency; and the machining process from the softened unit bamboo splint to the finished product is one-step molding.

Description

technical field [0001] The invention relates to a method for flattening and shaping unit arc-shaped bamboo strips. Background technique [0002] At present, the bamboo boards used in the market are basically the unit bamboo strips after being cut into pieces, which are first rough planed (to remove bamboo green and bamboo springs), and finely planed to make straight unit bamboo strips, which has low work efficiency and high yield. Low, the yield rate is basically between 20%-30%, and after using the curved bamboo strip shaping equipment, the yield rate is between 40%-50%, which is about 20% higher. Contents of the invention [0003] In order to overcome the disadvantage of low yield rate of bamboo in the process of processing, the present invention provides a method for flattening and shaping of unit arc-shaped bamboo strips, which can make efficient use of bamboo, and its yield rate is between 40% and 50%, and it can be formed at one time , the process method is easy...
