Abstract
The invention relates to a middle plate. The middle plate is formed by butt-jointing two or more than two short plates, wherein the grain direction of the short plates is consistent to the length direction; a plurality of bar-shaped slots are respectively arranged on two opposite width edges of the two adjacent short plates; strip bulges matched with the bar-shaped slots are formed between the adjacent bar-shaped slots; the strip bulge at one width edge is opposite to the bar-shaped slot position at the other width edge; two edges of the bar-shaped slots are parallel to each other; inner end parts of the bar-shaped slots are inward formed into tips; the outer end parts of the strip bulges are of tip shape matched with the inner end parts of the bar-shaped slots. The short plates of the middle plate are stably and firmly connected with each other, so that higher pull force can be endured and the smooth degree of the middle plate is higher.
Description
Technical field
The present invention relates to a kind of sheet material and butt-joint process thereof, specifically plate and butt-joint process thereof in one.
Background technology
Middle plate is often used as three-ply board and multiple-plate sandwich material, is a kind of wood chip veneer.Wood chip veneer is also called wooden skin, plank, is by the wood sheet material of peeler rotary-cut.Its thickness is generally between 1.0-4.6mm.
The manufacture process of middle plate needs two or more short slab to dock at width.In tradition, plate cuts the short slab 10(of corresponding upper hypotenuse 14 and lower hypotenuse 15 as shown in Figure 1 respectively by several two width edge) be spliced, during docking, the adhesion of short slab described in two or more 10 by upper hypotenuse 14 and lower hypotenuse 15 is interconnected.The docking mode of this middle plate makes the bonding force between short slab less, and two adjacent short slabs easily loosen, come off in use, affect the quality of whole glued board.In addition, two pieces of short slabs owing to being docked by hypotenuse, easily dock time stressed excessive and occur docking inaccurate situation, cause the out-of-flatness of docking site, thus affect flatness and the service property (quality) of whole sheet material.
Summary of the invention
The invention provides plate and butt-joint process thereof in one, its object is to the end docking intensity of the middle plate solved in three-ply board or multi-layer sheet and the not good problem of flatness.
Plate in one, in this, plate is docked by two or more short slab and forms, the grain direction of described short slab is consistent with length direction, just right two width edge of adjacent two short slabs offer some bar-shaped troughs respectively, form the rectangular protuberance agreed with bar-shaped trough between adjacent bar-shaped trough, the rectangular protuberance of a width edge and the bar-shaped trough position of another width edge just right.
Further, described bar-shaped trough both sides are parallel, and the inner end of described bar-shaped trough is inwardly formed pointed, and the outer end of described rectangular protuberance is agree with the inner end of bar-shaped trough pointed.
Further, described rectangular protuberance is narrowed gradually by wide from front to back, described bar-shaped trough is correspondingly broadened by narrow from outside to inside gradually, and the inner end of described bar-shaped trough is inwardly formed pointed, and the outer end of described rectangular protuberance is agree with the inner end of bar-shaped trough pointed.
Further, the both sides of described short slab rectangular protuberance are wherein provided with semicircle projection, and the both sides of the rectangular protuberance of another side are provided with the corresponding and semi-circular recesses agreed with mutually with it of bump position semicircle with this.
Further, described bar-shaped trough is inside pointed groove, and described rectangular protuberance is outside pointed protuberance.
Further, described bar-shaped trough both sides are parallel, and the inner end of described bar-shaped trough inwardly forms arc, and the outer end of described rectangular protuberance is the arc agreed with the inner end of bar-shaped trough.
A butt-joint process for plate according to any one of claim 1 ~ 6, its concrete steps are as follows:
(1) short slab of middle plate is positioned in frame, and is fixed with fixture;
(2) by grooving mould, some described bar-shaped troughs are offered to two of short slab width edge;
(3) gluing is carried out to the periphery of bar-shaped trough and rectangular protuberance;
(4) by fixture, width edge relative for adjacent two pieces of short slabs is carried out level docking, described rectangular protuberance is engaged with bar-shaped trough, form plate in monoblock.
Further, after fixing short slab with fixture in step (1), trimming finishing process is carried out to its width edge.
Further, by after two pieces of short slab docking in step (4), by parallel for the some strip hot melt tree laces outer surface sticking in two pieces of short slab junctions.
Further, by after two pieces of short slab docking in step (4), with hot plate, pressurizeed and left and right side pressure up and down in the docking site of short slab, and heat.
The invention has the advantages that:
(1) by the cooperation of rectangular protuberance and bar-shaped trough in width edge, the bond area of two pieces of short slabs is increased, larger pulling force can be born, not easily separated; It also avoid stressed excessive time two pieces of short slabs docked by upper and lower hypotenuse and cause irregular situation, two pieces of short slabs are docked mechanically, and do not affect its flatness.Thus also make with the three-ply board that is interlayer of plate in this or other multi-layer sheet more smooth.
(2) bar-shaped trough be set to outer narrow inner width and coordinate with front wide and rear narrow rectangular protuberance, or be respectively equipped with semicircle projection and semi-circular recesses in the rectangular protuberance both sides of two width edge, in conjunction with plank, there is certain flexible characteristic, make rectangular protuberance can overcome stand out under brute force, dock with bar-shaped trough level, and recover original shape and engage with bar-shaped trough, in addition abutment joint place carries out gluing, make it not be subject to external force to get loose, the transverse strength of plate in monoblock is increased, thus strengthen three-ply board or other multiple-plate mechanical strengths, improve product quality.
(3) end of rectangular protuberance and bar-shaped trough is set to pointed or arc, makes the seam after docking not be on same straight line, to prevent the fracture of docking site.
(4) use hot melt tree lace to be adhered to the outer surface of two pieces of short slab junctions, make the docking section potential energy of short slab keep smooth.
(5) docked the rear docking site to short slab pressurize and heat, high temperature is utilized to enable the glue melting of seam crossing and be evenly covered with gap, recycling pressure makes plate face be in same plane, and then increases the viscous force between two pieces of short slabs, makes two pieces of short slabs smooth simultaneously.
