Abstract

The invention discloses a production method of four-layer solid-wood composite floor boards, which comprises the following steps: raw edges of sheets are removed to form square sheets, pressure marks which have proper intervals and mutually staggered upper position and lower position are pressed on the upper surface and the lower surface of the square sheet along the lengthwise direction through a roller press, the square sheets with pressure marks are jointed into a floor blank by glue, veneers are stuck to the two faces of the blank to obtain a three-layer initial blank, and dash boards are stuck to the initial blank to obtain the four-layer floor board. Compared with the existing three-layer floor board, the production method overcomes a plurality of defects of the three-layer floor board, and has the advantages of less board core joints, large board, fine core, smooth surface, good quality, no waste and low production cost.

Description

The production method of four-layer real-wood composite floor

Technical field

The present invention relates to a kind of production method of solid wooden compound floor

The three-layer wood composite flooring that China produces at present is to be formed by the mutual vertical gummed of texture by dash board, central layer and base plate, and the dash board material is with sawing or the ornamental precious preferably broadleaf of slicing.Mostly core material is that quality does not have the softer timber of pin, broad-leaved of specific (special) requirements with the central layer of slab, the production of short and small material.Bottom is the weedtree monoblock veneer of rotary-cut.All materials all drying are handled, its production procedure is such: skin-material is that 2～4mm is thick, 40～80mm is wide, the broad-leaved material of the high-quality good decorative property that 180～500mm is long, good through four side moulder, it is wide to be combined into 200～220mm with glue and jigsaw machine, whole the panel that 2000～2200mm is long.The core material slab, short and small material is sawn into enough thick hair plates, with thicknesser power blader established practice lattice thickness plate, cross-section to Len req, the unhairing limit, vertical profile is the plate core that width differs, its width is between 20～50mm, thickness is 9～10mm, base plate is the monoblock veneer of rotary-cut, its length and width and panel match, its thickness is between 1.5～2mm, with central layer double spread and dash board, the base plate combination, through hot pressing, the saw limit, mortice opening, sanding, japanning finished product, making a general survey of above product and have certain defect, is example with the three-layer solid wood floor of a 2100 * 180mm in GB/T18103-2000 national standard: owing to the direct double spread of central layer is arranged plate, with panel, the base plate combination, will cause like this between central layer between the slit excessive, so that reduce floor intensity, in GB/T1803-2000 national standard, stipulate: " slit between the central layer bar can not greater than 5mm ", reduced three-layer wood composite flooring intensity like this; The second, its central layer bar can not cut into fritter, and fritter just causes waste, bulk can cause again the volume watt, cause the clocklike wavy vestige in floor.The 3rd, because its this arrangement moulding and structure causes its stress irregular, will cause the curved distortion that has influence on it of vertical bow, seriously can cause and scrap.The 4th, its panel abutted seam and central layer plate seam are strict dislocation, do not misplace and will reduce floor intensity, can cause the comparison burden like this in the big specification of industrialization is produced, we are called in line type three-layer wood composite flooring with the central layer arrangement this three-layer wood composite flooring.

Summary of the invention:

Task of the present invention will overcome the shortcoming of this in line type three-layer wood composite flooring exactly, reduces the cost of solid wooden compound floor, improves the solid wooden compound floor quality, makes the floor super quality and competitive price.

The present invention finishes like this: after slab, short and small material being sawn into the hair plates, drying of desired thickness, with hair plates thicknesser power blader established practice lattice thickness plate, disconnected to Len req, the unhairing limit, the side's of formation plate, with square plate by a upper and lower roller press that has combination garden blade, roller press is in the above and below of square plate, along its vertically extrude have impression, depth of cup that appropriate intervals, upper-lower position stagger mutually be thickness of slab 1/3rd to three branch two between, preferably 1/2nd of thickness of slab.The section configuration of impression can rectangle also can be below the rectangle, and and then the wedge shape of del is arranged.With central layer by having combination up and down, sharp garden blade roller press, (this crack is aforesaid rectangle to extrude the crack, the wedge shape that and then del is arranged below, be under zero the situation when its transverse width of garden cutter, because the thin thickness of garden blade, and timber has certain elasticity after plate passes through roller press, impression will origin, the wedge shape that certain width is arranged, become a crack), because on the square plate, following impression is to stagger mutually, even thereby the degree of depth of impression is 2/3rds of a thickness of slab, side's plate can not disconnect outside impression yet, because the present invention is on square plate, vertically extrude along it below and have appropriate intervals, on, the impression that upper/lower positions staggers mutually, these impressions can be with on the square plate, following stress is removed, thereby can be out of shape by the side's of avoiding coiled sheet song, the square bar that dimension saw need not be slit into so just, this sample prescription plate can directly be made the core bar and use, the side's of that is to say plate is exactly the bigger core bar of width, and perhaps the side's of we can say plate is exactly one and is pressed with that many impressions are separated by every impression and the less core bar of many width that do not cut off is formed the central layer that width is bigger.So just can avoid big, long plate is sawn into press for extracting juice, short core bar and cause waste (to comprise saw kerf consumption at least, the waste of fracture) with glue and jigsaw machine the square plate that a piece has impression is bonded to the first base of Len req and width floor, then log is screwed out the little veneer that is screwed out before the finished product veneer, short veneer with slicer with little veneer, short veneer processing and sorting is good, connect Len req with porose paper self-adhesive tape, on the first base of central layer, the applying glue of following two sides, veneer and first three layers of the bases of central layer is crisscross hot-forming on hot press, so be the blank of three-layer wood composite flooring.Three layers of blank are through the fixed thick sanding of coarse sand ray machine, good with prior four side moulder again, thicker Three kinds of hors d'oeuvres dash board of sawing or the thin only face dash board of slicing have been pieced together through the jigsaw machine, be bonded on three layers of blank that press through secondary hot pressing, obtain four-layer real-wood composite floor, mill through sanding four limits saws, mortice opening, japanning, finished product because the sandwich layer of four-layer real-wood composite floor is horizontally-arranged row adhesion moulding.Its both sides respectively put one with the lath of floor Len req outside, middle then be short arrangement, its adjacent two joints stagger, since central layer be bulk rectangular (referring to vertically be pressed with the square plate that staggers mutually in the appropriate intervals upper and lower position along it in square plate above and below) through roller press equally by GB/T18103-2000 national standard in a 2100 * 180mm be example, it is full that horizontal arranged type floor central layer is easy to row, because the central layer rectangular thereby labor and material saving that is bulk, the upper and lower layer usefulness of central layer be the short veneer of little veneer that rounding gets off.As everybody knows, a rounding processing will not screw out a lot of little veneers when going out certified products, short veneer, its percentage of A-class goods is very low, the four-layer real-wood composite floor of horizontally-arranged row just in time makes full use of these little veneers, short veneer, with those enough long little veneers, short veneer is processed with slicer, be connected to Len req with porose masking tape, through revolving glue, up and down in length and breadth with central layer and veneer, staggered glued together, obtaining the floor blank through hot press hot pressing has been three layers, its physical property is more much better than than in line three-layer wood composite flooring, it more tends towards stability, indeformable, stick three thicker jigsaw of sawing again on its surface, still stick thin only panel and do not produce distortion.

We are when producing in line row solid wooden compound floor, also can adopt four layers of mode to produce, because the above and below of central layer is vertically extruded appropriate intervals by roller press at it, the impression that staggers mutually in the upper and lower position, because its central layer is at the thin core of bulk, avoided the floor state that ripples, avoided the floor to become fritter to cause waste of material the central layer sawing for the state that do not ripple.This in line row four-layer real-wood composite floor, its central layer also are to risk central layer base just earlier with glue and jigsaw machine, so just eliminate the slit between central layer, make the central layer base form an integral body.The central layer just above and below of base is pasted by two layers of veneer and is shaped, and its bottom is the monoblock veneer, above one deck can paste with the enough long little veneer of several piece.It is irregular and bow that produce is curved that it has overcome three-layer wood composite flooring stress, overcome the shortcoming that the panel abutted seam of three-layer wood composite flooring and central layer splicing seams can not same positions, its physical property is than three laminated reasons, stable, not yielding, like this, stick the thicker Three kinds of hors d'oeuvres dash board of sawing again on its surface, still slicing is than thin only panel, and its quality is all good than three-layer wood composite flooring.Four-layer real-wood composite floor has been Duoed one deck and caused waste than three-layer wood composite flooring apparently, and is in fact the same with three-layer wood composite flooring the THICKNESS CONTROL of four-layer real-wood composite floor, just can not cause waste.Comprehensive four layers of horizontally-arranged row and the four layers of solid wooden compound floor that directly is listed as produced of enterprise, it can make all central layer veneers be fully used, and economic benefit of enterprises will be better.
