Abstract
The leveling process for raw bamboo sheet material includes the following successive steps: gradual developing via passing the arc bamboo sheet through rolling machine with roller possessing arc surface; the first leveling through rolling the bamboo sheet in the planar roller; reverse developing and the second leveling. The process with twice developing and twice leveling in both forward and reverse directions makes the leveled bamboo sheet possess only small cracks or even no cracks, no resilence. The present invention can reduce machining tolerance of bamboo sheet, raise bamboo material utilizing rate and reduce production cost.
Description
Technical field
What the present invention relates to is a kind of flattening method to raw material bamboo sheet.The technology field that belongs to the raw material bamboo wood.
Background technology
Present bamboo floor of using, be raw-material with bamboo chip exactly, raw material bamboo sheet all is to have certain radian usually, therefore when raw material bamboo sheet is processed into equal thickness, radian partly must be planed, to obtain the bamboo chip of equal thickness, radian is partly planed certainly will exist the waste of bamboo timber resource, and then has also increased the production cost on floor.
Summary of the invention
The objective of the invention is in order to solve present bamboo floor production waste of raw materials big, defect of high cost, a kind of flattening method of bamboo chip is provided, it can make have circular-arc, width carries out equal thickness processing again after 20～25 millimeters bamboo chip is by the processing of bamboo chip flattening method, can reduce the bamboo resource that the bamboo floor produces consumption, reduce production costs greatly.
Technical solution of the present invention: a kind of flattening method, its processing step branch to raw material bamboo sheet
One, gradual change flattens; Two, plane leveling for the first time; Three, oppositely flatten; Four, plane leveling for the second time.
Described gradual change flattening process step 1 is to have the bamboo chip of 20～25 circular-arc mm wides, from have the arc-shaped surface pressure roller machine identical, pass through with bamboo chip circular arc direction, the bamboo chip that has 20～25 circular-arc mm wides is under the roller roll extrusion that has cambered surface, and bamboo chip is flattened by gradual change.The pressure roller pressure that has arc-shaped surface pressure roller machine is 15KN, and flattening speed is 0.08m/s.
The described first time, levelling process step 2 in plane was with the bamboo chip after gradual change flattening process step 1, passed through from have the flat roll machine, will carry out the plane leveling under the roll extrusion of the bamboo chip behind the processing step one in having the plane roller.Technological parameter is the same.
Described reverse flattening process step 3 is that the bamboo chip after first time plane levelling process step 2 is oppositely flattened.Will be through the plane bamboo chip after the first time plane levelling process step 2, from the roller that has the reverse arc surface opposite, pass through with processing step one, further flattened under the roll extrusion of plane bamboo chip in having the roller of reverse arc surface.Adopt this step that bamboo chip is oppositely launched, can eliminate the circular-arc resilience of bamboo chip.Technological parameter is the same.
The described second time, levelling process step 4 in plane was the bamboo chip that oppositely flattens through processing step three, from have the flat roll machine, pass through, with the plane leveling of carrying out under the roll extrusion of the bamboo chip behind the processing step three in having the plane roller second time, bamboo chip is by smooth once more, thus typing.Technological parameter is the same.
Advantage of the present invention: owing to what adopt is flattening and twice leveling of positive and negative both direction, can be so that the expansion crackle of bamboo chip be little, and only there is tiny tortoise shape decorative pattern on the surface, even reaches surperficial free from flaw flattening.And bamboo chip is smooth, does not have circular-arc rebound phenomenon.Can reduce the allowance of bamboo chip thickness, improve utilization rate of bamboo.Greatly reduce production cost.
The specific embodiment
Embodiment 1:
Bamboo chip boiled 3～4 hours in 100 ℃ of water.
Bamboo chip after having boiled is by the flattening process of gradual change for the first time.Nip rolls pressure 15KN, flattening speed is 0.08m/s.
Subsequently, the bamboo chip after the flattening enters levelling process for the first time.Flattening roller pressure 15KN, leveling speed is 0.08m/s.
And then, the bamboo chip after the leveling enters flattening process for the second time.Nip rolls pressure 15KN, flattening speed is 0.08m/s.
At last, the bamboo chip after the flattening enters levelling process for the second time.Flattening roller pressure 15KN, leveling speed is 0.08m/s.
6 kilowatts of roll-in general powers.
Only there is tiny tortoise shape decorative pattern crack on bamboo chip surface after the flattening, and is smooth, do not have circular-arc resilience.
Embodiment 2:
Bamboo chip charing 3～4 hours in the retort of 140 ℃ of temperature.
Bamboo chip after the charing is by the flattening process of gradual change for the first time.Nip rolls pressure 15KN, flattening speed is 0.08m/s.
Subsequently, the bamboo chip after the flattening enters levelling process for the first time.Flattening roller pressure 15KN, leveling speed is 0.08m/s.
And then, the bamboo chip after the leveling enters flattening process for the second time.Nip rolls pressure 15KN, flattening speed is 0.08m/s.
At last, the bamboo chip after the flattening enters levelling process for the second time.Flattening roller pressure 15KN, leveling speed is 0.08m/s.
6 kilowatts of roll-in general powers.
Only there is tiny tortoise shape decorative pattern crack on bamboo chip surface after the flattening, and is smooth, not circular-arc resilience.
