At length explain the present invention below.
In the method for the invention described above, the raw material that uses in step (1) must be bright bamboo, if use dried bamboo or wet the back as raw material with dried bamboo bubble, then breaks easily in the spreading operation.
Jut in step (2) on the said thick bamboo tube outer surface mainly refers to ring, when shooting off jut, notes the surf green of remainder not being shootd off.Available hand gently is pressed in slotted opening place on the cylindrical planing machine workbench with thick bamboo tube in the operation of this operation, at this moment thick bamboo tube can rotate with the rotation of cutter shaft, thereby the jut on the whole outer surface can be eliminated but allow the whole surf greens beyond the ring keep.
Fresh arc bamboo chip must be heated to the spreading of 180～220 ℃ of ability in above-mentioned steps (5), if temperature is lower than 180 ℃, then bamboo chip is softening inadequately, breaks easily during spreading.If temperature is higher than 220 ℃, then bamboo chip has roasting danger of sticking with paste, and therefore heating-up temperature is defined as 180～220 ℃, preferred 190～210 ℃.
In above-mentioned steps (6) with two plate shaped bamboo chips according to surf green outwardly and the parallel mode of fiber pattern bonding, the anti-wear performance that so both can make the upper and lower surface on bamboo floor all obtain surf green to be had, the distortional stress that exists in the single face bamboo chip is cancelled out each other, thereby guarantee that pairing bamboo floor is out of shape never.
The special equipment of the invention described above comprises cylindrical planing machine, interior round profiling plane tube machine and two roller rivet bucker.
In the circular plane flat-bed machine, said baffle ring has two at least outside, and preferably three, they equidistantly scatter on cutter shaft, limit processing capacity by the knife height that exceeds baffle ring.The 0.2mm because the knife height that exceeds baffle ring is only had an appointment, and at first partly contact with ring adding the man-hour blade, so generally can not injure surf green.The width of the distance between cutter shaft and the work top and the slotted opening that is used to admit cylindrical workpiece is relevant with the diameter of cylindrical workpiece, but blade must be a little less than the upper surface of work top, and can touch workpiece with blade is appropriateness.For example,, process the bigger workpiece of diameter if desired and blade does not reach workpiece, then cutter shaft slightly can be raise when the width of slotted opening fixedly the time.When the processing diameter is more or less the same thick bamboo tube in 60～100mm scope of diameter for example, do not need to adjust the height of cutter shaft, only need get final product by feel control processing capacity.
The principle of circle profiling plane tube machine is different from common thorax bed in above-mentioned, is circular fully with common thorax bed processed workpiece inner chamber.Therefore, when the thick bamboo tube ovalize, must be became uneven with the thick bamboo tube after the common thorax bed processing.And a circle profiling plane tube machine promotes travel(l)ing rest by adjusting handle in of the present invention, so that the secondary axis of guide rises or descends, the distance of the secondary axis of guide and blade is changed, adopt stop to control the rising degree of travel(l)ing rest simultaneously, thereby guarantee that the thick bamboo tube after the processing has wall thickness fully uniformly.
Above-mentioned pair of roller rivet bucker has three pairs of pressure rollers, and these three pairs of pressure rollers preferably are on the same level height so that workpiece can waltz through pressure roller most.Each must descending gradually changing to the gap of pressure roller, so just can make bamboo chip progressively be rolled into the plane.The main transmission chain must make three pairs of pressure rollers rotate with equidirectional, otherwise workpiece can't pass through follow-up pressure roller after by first pair of pressure roller.The purpose of coated metal net sheet is the interior arc length that is used to change workpiece on the pressure roller.Only in every pair of pressure roller on the purpose of pressure roller coated metal net sheet be only to allow the wire netting sheet contact with the inner surface of bamboo chip, thereby the assurance surf green is injury-free.
Compare with process equipment with the bamboo floor and the processing method thereof of prior art, the present invention has following beneficial effect:
The bamboo floor of prior art is spliced by many slice bamboo chips, has many pieces, and must use more adhesive, and its structural strength is poor, deforms easily.In addition, owing to there is not the spreading operation, therefore must partly shoots off curved surf green so that the monoblock floor is smooth, thereby the wearability on floor is greatly reduced.And whole seamless double joint bamboo floor monoblock of the present invention do not have piece, and the highest surf green of scuff resistance is retained fully, and is used for two bonding bamboo chips and is the minute surface symmetry, so internal stress is eliminated fully, thus distortion never.In addition, be used to make the manufacture method of whole seamless double joint bamboo floor of the present invention, its operation is simple; Special equipment modern design in the method, good stability, yield rate height.
