Problems solved by technology

[0003] The purpose of the present invention is to solve the defects of large waste of raw materials and high cost in the current production of bamboo flooring, and provide a method for flattening bamboo slices, which allows arc-shaped bamboo slices with a width of 30 to 100 mm to pass through the bamboo. After the sheet flattening method is processed, the equal thickness processing can reduce the consumption of bamboo resources and greatly reduce the production cost

Embodiment 1

[0013] The arc-shaped bamboo slices with an arc length of 30 millimeters are cut into equal width bamboo slices with parallel sides. Place in a plane hot press (model zy3-130) with a lateral press mechanism, press plate temperature at 180 degrees, keep the pressure at 0-0.2Mpa for 3 minutes and then press gradually until the bamboo slices are flattened. Continue to keep the pressure at 0.5Mpa for 5 minutes after the bamboo sheet is flattened. While the bamboo slices are gradually flattened, the width of the bamboo slices increases with the expansion of the arc length of the bamboo slices. At this time, the lateral pressing mechanism (model zy3-130-c) moves in the width direction to meet the Expand the arc length (width of the bamboo slices) and ensure the lateral pressure on the bamboo slices (0-0.2Mpa), so that the arc-shaped bamboo slices are flattened under the simultaneous action of lateral pressure and vertical pressure, reducing or reaching the bamboo slices. The inner ...

Embodiment 2

[0015] The arc-shaped bamboo slices with an arc length of 100 mm are sawed into bamboo slices with parallel sides of equal width. Place in a plane hot press (model zy3-130) with a lateral press mechanism, press plate temperature at 220 degrees, keep the pressure at 0-0.2Mpa for 3 minutes and then gradually pressurize until the bamboo slices are flattened. After the bamboo slices are flattened, continue to hold the pressure for 5 minutes under a pressure of 2.0Mpa. While the bamboo slices are gradually flattened, the width of the bamboo slices increases with the expansion of the arc length of the bamboo slices. At this time, the lateral pressing mechanism (model zy3-130-c) moves in the width direction to meet the Expand the arc length (width of the bamboo slices) and ensure the lateral pressure on the bamboo slices (0-0.2Mpa), so that the arc-shaped bamboo slices are flattened under the simultaneous action of lateral pressure and vertical pressure, reducing or reaching the bamb...

Embodiment 3

[0017] After carbonization, the arc-shaped bamboo slices with an arc length of 55 mm are sawn into bamboo slices with parallel sides of equal width. Place it in a plane hot press (model zy3-130) with a lateral press mechanism, press plate temperature at 200 degrees, keep the pressure at 0-0.2Mpa for 3 minutes and then press gradually until the bamboo slices are flattened. After the bamboo slices are flattened, continue to hold the pressure for 5 minutes under a pressure of 1.25Mpa. While the bamboo slices are gradually flattened, the width of the bamboo slices increases with the expansion of the arc length of the bamboo slices. At this time, the lateral pressing mechanism (model zy3-130-c) moves in the width direction to meet the Expand the arc length (width of the bamboo slices) and ensure the lateral pressure on the bamboo slices (0-0.2Mpa), so that the arc-shaped bamboo slices are flattened under the simultaneous action of lateral pressure and vertical pressure, reducing or...

Abstract

The invention relates to a method for flattening the arc bamboo plate, wherein it cuts arc bamboo plate into arc plate with parallel edges to be put in thermal compressor with adjustable side compressor; compressing and flattening the bamboo plate; the side compressor moves along width; keeping pressure at 0.5-2.0MPa for 5min, shaping it. The invention can soften the bamboo plate, and it can flexibly adjust the width and pressure on bamboo plate; and it can improve the efficiency.

Description

technical field [0001] The invention relates to a method for flattening original bamboo arc-shaped bamboo slices. The invention belongs to the technical field of processing technology of raw material bamboo. Background technique [0002] Because bamboo is a round, hollow stem plant. Therefore, for many years, in the industrial application process of bamboo, in order to obtain flat bamboo chips with a certain width and thickness, bamboo is divided into bamboo strips or bamboo strips, and then processed into bamboo chips of equal thickness for application. And bamboo chip must be planed off the natural circular arc part of bamboo in carrying out equal thickness processing process, just can make the plane bamboo chip of equal thickness, has caused a large amount of waste of bamboo material raw material like this, and bamboo material output rate is low. Contents of the invention [0003] The purpose of the present invention is to solve the defects of large waste of raw mater...
