Problems solved by technology

[0003] Moso bamboo with high economic value, the widest distribution and the largest output in China has a diameter at breast height of about 7 to 12 centimeters; and the bamboo is also characterized by thin and hollow walls and a large degree of taper; the outer layer of the bamboo is dense and the texture is Hard, smooth surface, with a layer of wax, poor wettability to water and adhesives; the inner layer of bamboo yellow tissue is loose, fragile, poor wettability to water and adhesives; the middle bamboo meat, performance is between Between green bamboo and yellow bamboo is the main part of bamboo utilization; according to traditional bamboo processing methods, the utilization rate of bamboo is less than 30%, which also partially causes the problem that the price of bamboo products remains high at present; therefore, we must start from Starting from the bamboo processing technology, a new bamboo processing technology has been developed, which greatly reduces the complexity of the current bamboo processing technology, solves the problem of low material yield in bamboo processing, and can comprehensively improve the technological content of the bamboo product industry and product added value

Embodiment Construction

[0029] Such as Figure 1-2 Shown, a kind of processing method of high-temperature quenching softening and flattening of round bamboo comprises the following steps:

[0030] Step 1: Select fresh moso bamboo, remove the sundries on the bamboo stem, cut it into 0.5-2.6m round bamboo sections, and set aside;

[0031] Step 2: send the truncated round bamboo sections into the machining process for removing outer joints, and remove all the raised outer joints of the round bamboo sections;

[0032] Step 3: Send the round bamboo section from which the outer section has been removed to the machining process to remove all the inner sections of the round bamboo section;

[0033] Step 4: Send the round bamboo section from which the inner section has been removed to the slitting saw, and open a through sawing path 12 along the length direction of the round bamboo section on the side of the round bamboo section for standby;

[0034] Step 5: Put the round bamboo section sawn on the side int...

Abstract

The invention relates to a processing method of round bamboo high-temperature hardening, softening and flattening. The method comprises the steps that moso bamboos are selected and cut into standard round bamboo sections, outer and inner knots are removed, and the round bamboo sections are laterally sawn; the laterally-sawn round bamboo sections are soaked with hot water and fed into a round bamboo high-temperature hardening and softening device to be baked and softened, after preset softening requirements are met, a valve of a water storage groove is opened, water in the water storage groove is sprayed to the high-temperature baked round bamboo sections, and hardening and softening treatment is completed; and finally, the hardened and softened round bamboo sections are taken out to be fed into a bamboo flattening machine to be flattened, the flattened bamboo boards are fed into a two-side surface planer to be processed, and standard displayed bamboo board finished products are manufactured. By means of the method, the process complexity of existing bamboo material processing can be lowered, the problem that the outturn percentage is low in bamboo material processing is low is solved, the technological content and product added value of bamboo product industry can be comprehensively improved, and the development prospect is wide.

Description

technical field [0001] The invention relates to a processing method for softening and flattening round bamboo by high-temperature quenching. Background technique [0002] China is the country with the most abundant bamboo resources in the world. There are about 40 genera and 500 species. The types, area and volume of bamboo forests rank first in the world, with a total bamboo forest area of ​​4.2 million ha 2 above, of which moso bamboo accounts for 70%. In the past two decades, the bamboo forest area in the country has increased by 50,000 hm2 per year. 2 The speed is increasing, and the scientific research on bamboo forest cultivation, bamboo material properties and processing and utilization has made breakthrough progress, which provides favorable conditions for the processing of bamboo into various products to meet the needs of economic construction and people's lives. [0003] Moso bamboo with high economic value, the widest distribution and the largest output in China...
