Production process and equipment for round bamboo expansion flat plate

Abstract

The invention discloses a production process for a round bamboo expansion flat plate and an expanding, shaping and thickness-fixing all-in-one machine. The process comprises the following steps: sawing round bamboo off, removing outer and inner segments to form a bamboo barrel, digging grooves in tabasheer on the inner surface of the bamboo barrel, and putting the bamboo barrel into a 0.5-1.5 mass percent sodium pyrosulfite aqueous solution for storing; (2) slitting the bamboo barrel stored in the sodium pyrosulfite aqueous solution, softening at a high temperature, expanding, cooling for shaping, and planing and fixing thickness on double sides to obtain the round bamboo expansion flat plate. In the all-in-one machine, an expansion drum, a shaping barrel and a thickness-fixing planer tool are arranged in sequence on the same conveying belt, thereby realizing combination of three procedures and increasing the mechanical and automatic degrees. By adopting the production process and the all-in-one machine, the production of the round bamboo expansion flat plate is not influenced by weather or limited by raw materials any more, the technical problems of deterioration and drying of round bamboo stored under the natural condition are effectively solved, continuous large-scale production is realized, and the product quality is good. The production process and the all-in-one machine have high practicability and wide application prospects.

Description

technical field [0001] The invention relates to a production process of round bamboo unfolded flat plate and an integrated machine for unfolding, shaping and thickness setting. Background technique [0002] my country is the country that produces the most bamboo in the world, accounting for more than 90% of the world's total bamboo resources and is widely distributed. There are large bamboo forests in Zhejiang, Fujian, Hunan and other places. The growth cycle of bamboo is shorter than that of trees, with superior performance and fast renewal speed. Replacing wood with bamboo is not only economically cost-effective, but also conducive to protecting forests and preventing large-scale felling of forests. Therefore, bamboo can not only "replace wood", but also "win wood". [0003] There are many ways to utilize bamboo, and it is one of the very effective ways to expand the round bamboo into a bamboo slab, but the existing round bamboo slab production process and equipment have ...

AI Technical Summary

Problems solved by technology

[0004] First, raw materials cannot be purchased and stored in large quantities

If too much original bamboo is purchased, storage under natural conditions will lead to deterioration or loss of moisture, which will greatly reduce the qualified rate of bamboo after expansion

Because the deterioration will make the bamboo unusable, and the loss of moisture will increase the chance of breaking the bamboo during the unfolding process, and it will also increase the cost of cooking and softening

Since the raw materials cannot be stored, the roads are slippery in rainy days, and farmers are unwilling to cut bamboo, the enterprise has to face the dilemma of stopping production. Therefore, continuous and large-scale production cannot be realized, which also affects economic benefits.

[0005] The 2nd, existing bamboo unfolding equipment automation and continuous degree are very low, and work efficiency is also low, has improved production cost

[0006] The third is that cracks are prone to appear during the unfolding process of the round bamboo, which affects the qualified rate of the product

[0007] The fourth is that the bamboo green and bamboo yellow are not removed when the round bamboo is unfolded into a flat plate. The thickness of the flat plate is the natural wall thickness of the bamboo tube.

[0008] Therefore, the existing round bamboo unfolding technology cannot meet the requirements of modern production, and is far from reaching people's expectations, and needs to be improved.
