Problems solved by technology

However, the cross-section of bamboo varies in size and is not a standard circle, especially the rotary-cut bamboo veneer process requires the ellipticity of the bamboo to be as small as possible, and it is difficult to achieve large-scale production of bamboo without shaping
In addition, natural bamboo is prone to cracking during use, which limits its scope of use; it is also easy to attract insects, absorb water and rot easily
[0004] The moisture content of natural bamboo is uneven and generally low, the plasticity is poor, and processing is difficult

Embodiment 1

[0032] (1) Select fresh moso bamboo without mildew and rot defects, with a diameter between 100 and 160 mm, and saw and cut it into bamboo tubes according to the length of use; then, the outer nodes, inner nodes and bamboo partitions of the bamboo tubes are respectively removed from the outer nodes and the inner parts. Remove it on the knot machine, so that the outer joint of the bamboo tube has no protrusion, and the inside is hollow. After sawing, the wall thickness of the small end of the bamboo tube is H 1 , the bulkhead wall thickness is H 2 .

[0033] (2) cutting the bamboo tube. Cut off a part along the longitudinal direction of the bamboo tube, according to the arc length formula or Calculate the size of the central angle corresponding to the arc that needs to be cut out, wherein, the size of the central angle corresponding to the cutout arc, the inner diameter circle is slightly larger than the outer diameter circle, so that the length of the arc length of the sm...

Abstract

The invention discloses a method for preparing a hollow raw bamboo and equal-diameter bamboo cylinder, and relates to the technical field of bamboo processing and utilization. Including the following steps: S1: material selection; S2: preparation of bamboo tube; S3: removal of bamboo joints and bamboo partitions; S4: calculation and cutting; S5: softening of bamboo tube; S6: shaping and drying of regular round table bamboo tube; body preparation. In this way, the bamboo tube with a certain degree of sharpness can be shaped into a large-scale production of the hollow equal-diameter bamboo tube. Equal-diameter bamboo tubes can be used for rotary cutting bamboo veneers, which greatly improves the utilization rate of bamboo tubes for bamboo veneer decorative materials prepared by rotary cutting methods. It is also suitable for making bamboo furniture, bamboo buildings, bamboo handicrafts, guardrails and bamboo outdoor landscapes. It is of great significance to improve the utilization rate and expand the field of bamboo utilization.

Description

technical field [0001] The invention relates to a method for preparing hollow raw bamboo and equal-diameter bamboo cylinders, belonging to the field of bamboo processing. Background technique [0002] Bamboo grows fast, usually within 3 to 5 years, and is currently the best wood substitute. Bamboo resources are abundant in the south of the Yangtze River in my country. Moso bamboo is the most widely planted bamboo, and there are also bamboos with larger diameters. Such as giant dragon bamboo, dragon bamboo, Yunnan hemp bamboo, and small-leaved dragon bamboo. The bamboo stalks of these bamboos are thick and straight, 30 meters high, 20-30 cm in diameter, and 17-22 cm long between nodes. They are naturally suitable for making structural materials. Therefore, our country has the potential to become a bamboo processing base. Using bamboo instead of natural solid wood can effectively alleviate the current situation of insufficient forest resources in our country. [0003] In additi...
