A processing method for forming bamboo strips

Abstract

The invention discloses a processing method for bamboo strip forming. The method comprises the steps that (1) bamboo is cut off according to need and chipped into sheets, bamboo joints are removed and bamboo strips are obtained; (2) a concave arc-shaped surface of a Shiraia layer is processed into a concave arc-shaped surface or a plane, a convex arc-shapes surface of a bamboo green layer is processed into a convex arc-shaped surface, and oblique sides on both sides of each bamboo strip are processed into oblique sides or straight side; (3) the bamboo strips are in a rough regular shape after being dried; (4) the dried bamboo strips are finish planed, processed and formed into a smooth regular shape. According to the processing method for bamboo strip forming, the principle that the Shiraia layers and the bamboo green layers of the bamboo strips have different shrinkage degrees when being dried due to density difference is utilized, the processing step of cutting the convex arc-shaped surfaces of the bamboo green layers is omitted, so that the good effects of improving the efficiency by above 20 percent, effectively reducing the material cost, and improving the processing and utilization rate of bamboo are achieved.

Description

technical field [0001] The invention relates to a processing method of bamboo, in particular to a processing method of forming bamboo strips. Background technique [0002] Bamboo is a unique resource in my country and Southeast Asia. It has the advantages of large accumulation, good physical and mechanical properties, and fast growth. In my country, the utilization rate of bamboo is very large. Bamboo products such as bamboo boards, bamboo mats, bamboo pillows, bamboo windows and bamboo handicrafts made of bamboo have penetrated into people's lives, not only providing people with comfortable and practical daily necessities, And it has an aesthetic effect. Bamboo includes bamboo green, bamboo flesh and bamboo yellow. Bamboo green is in terms of color. The outer skin of bamboo has a high density and rich longitudinal fibers. Because it is green when it is fresh, it is called green bamboo. The yellow side of the bamboo cavity is called bamboo yellow because of its low porosity...

Problems solved by technology

[0008] In the above-mentioned processing process, because the irregular cross-section of the bamboo strip is cut off twice (step 1 and step 4), therefore, this method causes a large amount of waste loss of material

[0009] In order to reduce the loss of material waste, at present, the entire bamboo industry manufacturers without exception adopt the second carbonization (that is, dry carbon) of one-carbon dry strips to make the dry strips swell and expand, and then dry them for the second time, commonly known as Two carbon dry strips, but in this way the density, hardness and flexibility of the bamboo strips are all greatly reduced, which not only affects the product quality and output, but also prolongs the production cycle and increases the production cost. This is extremely to be solved. technical bottleneck
