Moso bamboo extrusion flattening processing device and extrusion flattening processing method

Abstract

The invention relates to a moso bamboo extrusion-flattening processing device and a moso bamboo extrusion-flattening processing method. The moso bamboo extrusion-flattening processing method comprises the following steps: segmenting fresh moso bamboos, removing inner and outer joints, notching, soaking in hot water, softening by baking at high temperature, and sending into a moso bamboo extrusion-flattening device to prepare a large-breadth extrusion-flattened bamboo board. The moso bamboo extrusion-flattening processing device comprises a machine frame, a feeding device and an extrusion-flattening device, wherein the machine frame comprises a frame body, a machine table and a platform; the extrusion-flattening device comprises an extrusion-flattening tongue plate, a driving motor and a lifting platform; the front end of the extrusion-flattening tongue plate is a conical part; the back end of the extrusion-flattening tongue plate is a flattening part; lower pressing rolls are arranged inside the flattening part; upper pressing rolls matched with the lower pressing rolls are arranged inside the lifting platform; lower pressing roll rotating shaft at one ends of the lower pressing rolls are in belt or chain transmission with the output shaft of the driving motor; the feeding device is positioned in front of the extrusion-flattening tongue plate. Through the moso bamboo extrusion-flattening processing device and the moso bamboo extrusion-flattening processing method, the problems that in the current bamboo flattening processing process, the flattened bamboo board is small in breadth size and serious in decline in physical and mechanical properties are solved, and the scientific and technological content in the bamboo product industry and the added value of a product are comprehensively increased.

Description

technical field [0001] The invention relates to an extrusion flattening processing device and an extrusion flattening processing method of moso bamboo. Background technique [0002] The 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. Moso bamboo has the characteristics of thin and hollow walls and large taper; the outer bamboo green tissue is dense, hard, smooth, with a layer of wax, which has poor wettability to water and adhesives; the inner bamboo yellow tissue is loose, The texture is fragile, and its wettability to water and adhesives is also poor; the bamboo flesh in the middle, whose performance is between bamboo green and bamboo yellow, is the main part of bamboo utilization. The traditional flattening processing method of bamboo has a series of problems such as the small size of the flattened bamboo board and the serious decline in the physical and mechanical...
