The utility model discloses a new type of wood core board, which comprises a number of log core longitudinal bonding strips. The longitudinal bonding strips are formed by pressing and bonding the log cores processed by local planing on four sides, and there are concave meshing parts on the bonding surface or the lower side of the two adjacent log cores. The meshing parts are formed by milling with special milling cutters. The joint part is meshed with the convex part of the other adjacent vertical adhesive strip, and the two parts are closely contacted. The log core processed by local planing on four sides includes four section planes and four arc segments, the relative section planes are parallel to each other, and the adjacent section planes are perpendicular to each other, and the arc segments are connected between the adjacent section planes. The new wood core board of the utility model can cut only part of the arc when processing, which can reduce the processing amount of the log core and improve the utilization rate of wood raw materials; by staggering the bonding seam of the wood core through tooth meshing, the bonding area of glue is increased without much reduction of the processing amount of the milling tooth surface, and the bonding area of the wood core board is increased. Combined strength.

,具体涉及一种新型木芯板。
技术介绍
桉木的木芯有较高的强度和硬度,可以用于家具板材的制作。由于桉木的价格优势,近几年桉木芯板已经引起了家具生产商的注意。木芯板的生产工艺主要就是通过对原木芯进行初加工,然后利用胶水将木心粘合在一起形成实心木材,再根据需要进行剪裁和开板。图1是圆木芯的结构示意图,图2是现有铣平面和压合截面的示意图。现有的加工工艺是将圆木芯板的四个面全部刨平,刨成正方形木条然后再进行胶合,这样圆形木料的四边圆弧全部刨掉,木料的浪费非常严重。
技术实现思路
为了解决现有技术存在的上述技术问题,本技术提供了一种新型木芯板,由原木芯加工胶合而成,包括若干原木芯纵向粘合条,所述纵向粘合条分别由四边局部刨平加工的原木芯纵向排列压紧粘合而成,相邻两原木芯的粘合面上或下侧设有凹陷的啮合部,所述啮合部由专用铣刀铣削而成,所述啮合部与另一相邻纵向粘合条铣削后形成的相对位置的凸部相互啮合,两者紧密接触,相互粘合。优选地,所述四边局部刨平加工的原木芯包括4个剖平面和4个圆弧段,相对的剖平面相互平行,相邻的剖平面相互垂直,所述圆弧段连接在相邻剖平面之间。本技术新型木芯板,加工时只切掉部分圆弧,能够减少对原木芯的加工量,提高了木材原料的利用率;通过齿状啮合错开木芯的粘合缝,在不需要多大的减少铣齿面加工量情况下,增加了胶水的粘合面积,提高木芯板的粘合强度。附图说明图1是原木芯的结构示意图。图2是现有技术的木芯板铣平面和压合截面的结构示意图。图3是本技术的木芯平面铣截面图。图4是本技术的木芯粘合图。图5是本技术的平板啮合加工面截面图。图6 ...
