Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] see figure 1 , figure 2, in the embodiment of the present invention, the device that is used for thermal shaping of bamboo block comprises the horizontal supporting roller 2 that is used to convey the arc-shaped bamboo block that is installed under the leftmost end of frame platform 1 and the lateral guide roller that its left end both sides are installed 3. On the frame platform 1, the first stage profile roll 4, the profile roll 5 to the profile roll 13 of other stages are installed successively, and the cooling and setting roll 14 to the cooling and setting roll 19 of each level behind it. The upper roll width of the first stage profiled roll 4 is narrower than its lower roll width, and the upper roll width of other level profiled rolls gradually increases to be consistent with its lower roll width, and the lower roll width of eac...

Abstract

The invention discloses a bamboo block thermal shaping method and device. The bamboo block thermal shaping method provided by the invention is a machining method for implementing the shaping of the walls of the bamboos and comprises the following steps of: extruding and unfolding bamboo blocks by utilizing multiple grades of bunching gradient profile rollers by means of certain thermoplasticity of the walls of the bamboos which are boiled and are softened at high temperature under the allowed condition of horizontal allowed stress of the bamboo materials, and cooling and shaping. The device provided by the invention mainly comprises a horizontal support roller and lateral guide rollers, wherein the horizontal support roller which is used for conveying arc bamboo blocks is installed below the foremost end of a rack platform; the lateral guide rollers are installed at two sides at the front end of the rack platform; the rack platform is also sequentially provided with a first grade profile roller, other multiple-grade profile rollers and multiple-grade cooling and shaping rollers; and the profiles of the upper roller and the lower roller of each grade profile roller are matched with a flower-type unfolding pattern of the shaping for the bamboo materials. The device provided by the invention is simple in structure, and is convenient to use, and the integrity and horizontal intensity of the walls of the bamboos after being shaped are ensured, thus the arc bamboo blocks are unfolded into bamboo sheets with good integrity under the pressure of rolling.

Description

technical field [0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a thermal shaping method and device for bamboo blocks. Background technique [0002] my country's bamboo resources are very rich, and bamboo forests are known as the second forest. While forest resources have been severely damaged worldwide and their stock volumes are declining, bamboo resources are showing an obvious growth trend. Bamboo has high strength, good elasticity, stable performance, and low density. It is a typical organism with good mechanical properties existing in nature. At present, with the restrictions on timber resources in various countries, people are beginning to make more use of environmentally friendly and fast-growing bamboo, and apply it to various fields such as furniture, daily necessities, and building materials. However, bamboo is a hollow cone with a small diameter, generally 10-20m high, 7-12cm diameter at breast height, thin ...
