Description

Fiber wood cellular board and moulding process

The invention belongs to the composite honeycomb sandwich structures technical field, particularly wad and the compound moulding process of making plate of Weft wood fabric folded honeycomb core.

Technique known is at present: the honeycomb structure composite material is rational in infrastructure because of having, lightweight, high-strength, series of advantages such as materials province and always be the emphasis of composite material application and development area research, the covering and the sandwich material kind that develop sandwich structure so far are a lot, skin material commonly used has aluminum alloy book plate, titanium-alloy thin-plate, glass fibre reinforced plastics book version, wooden plywood, single wood plate, the inorganic composite materials plate, plastic board, glass fiber cloth, aramid fiber cloth, cotton and paper or the like, honeycomb core commonly used has paper honeycomb core, the frp honeycomb core, plastic honeycomb core, aluminum alloy honeycomb core, aramid fiber honeycomb core or the like, just can develop many kinds of honeycomb composite sandwich construction materials with every kind of covering and different comb cores are compound, most widely used product mainly is the paper paper honeycomb core now, various man-made board facial tissue honeycomb cores, glass fibre reinforced plastics and frp honeycomb core and aluminium and aluminium honeycomb core sandwich structure etc.

Various paper honeycomb core sandwich material waterproof, humidity resistance are limited, and it is limited to expose intensity, and application area is restricted.Sandwich materials such as frp honeycomb, aluminium honeycomb, aramid fiber honeycomb are because of the price height, and application area neither be very wide.Also have by modular compound molding at intermittence, labor intensity is big, efficient is low, but equipment investment is few, and size change over is flexible, can satisfy all single products needs.How can find the advantage of the existing paper of a kind of material unit compound molding, good performance is arranged again, price is not high yet simultaneously.

The objective of the invention is: make skin material and the compound a kind of forming method of Weft wood fabric folded honeycomb core by utilizing wad, make the modular construction composite sheet of wad honeycomb interlayer with it, it is extensive that used wood materials has raw material sources, renewable is strong, along the grain compressive strength is big, renewable reaches cheap characteristic by force, be with flexible fiber and warp, latitude wood chip bar is weaved or the non-woven different disadvantage of mechanical property of together having eliminated the batten sheet, its moulding process is simple, product can be widely used in the man-made board application, building materials field, wrapper field or the like, and other all fields to the interlayer composite material demand.

The present invention solves technology side that its technical problem adopts by being: at first a reel Weft wood fabric is contained on the reel on the cloth holder; Weft wood glass fabric is imported the horizontal gluing of horizontal glue applicator of rubber-coated mechanism by preceding guide reel, it is to utilize vertical reticulate pattern bar of glue applicator or longitudinal groove corresponding wood chip bar on Weft wood glass fabric to be coated with lateral separation bar shaped glue, respectively there is a cover rubber-coated mechanism to realize that the Weft wood glass fabric both sides replace gluing in the both sides of gummed cloth, length alternately equals following folding length, alternately point equals folding point, the speed and the switching between the rubber-coated mechanism of Weft wood glass fabric and glue applicator need realize synchronization control, should guarantee that folding back adjacent surface laterally is coated with the adhesive tape of overwood latitude bar width integral multiple along wooden latitude bar, width between the adhesive tape is to be coated with 4 times of adhesive tape width, gummed cloth adjacent surface adhesive tape staggers, and the one side adhesive tape is in the centre of two adhesive tape of adjacent surface exactly; The Weft wood glass fabric that was coated with glue through after Guide roller enter the heating cabinet heating as required, again through one or more Guide roller guiding, make its length back and forth folding on folding platform by the drive of fabric folded mechanism by design, be to cooperate with the tight mechanism of an intussusception head-clamp each side by band cloth mechanism to realize accurate folding, the location, the folded tight mechanism of head-clamp is a pair of cooperation in front and back, to guarantee is to clamp same batten sheet simultaneously to make it press to folding platform in front and back, and keep-up pressure until another tight mechanism of folded head-clamp unclamps after depressing again, start following one deck cloth that execution is brought by band cloth mechanism, opposite side is in clamped condition always and unclamps after this side is depressed again again, start execution by band cloth mechanism's band following one deck cloth in the past, so alternate cycles is folding; Fold mechanism removes and includes the folded tight mechanism of head-clamp, band cloth mechanism, and folding platform comprises that also other guarantees that each mechanism effectively is connected the assisting agency of cooperating; Folding into needs thickness Weft wood glass fabric end socket to cut into the honeycomb core folded piece, by folding platform move or fold on the platform the line belt band from, abdicate folding platform simultaneously and continue folding next piece honeycomb core folded piece, the honeycomb core folded piece is delivered to pressurization or is pressurizeed, is heated and cured into broadwise honeycomb core raw sheet as required; The honeycomb core raw sheet is through cutting into the Wooden honeycomb core bar perpendicular to broadwise batten sheet by the length of honeycomb height, and the width of honeycomb core strip just equals folded length; Honeycomb core strip satisfies usage requirement and can be used as the use of honeycomb pellet, otherwise sticks into the honeycomb pellet through assembly, uses as modular honeycomb core; If width is not enough, also need to arrive the width that needs through horizontal butt joint one or many, finally become the modular Wooden honeycomb core piece that satisfies the length needs; Modular honeycomb pellet drawn again is launched into the Wooden honeycomb core that wood chip bar rift grain is erect; Wooden honeycomb core fixedly is fixed to the Wooden honeycomb core plate through spray glue dipping as required; Modular Wooden honeycomb core plate as required up and down gluing become the plate pah that does not have the fiber wood cellular board of edge sealing on four sides with two sides single or multiple lift wad surface layer clad can; Heat as required, pressurize or to heat pressurization compound with changing into modular fiber wood cellular board; Can be without Wooden honeycomb core plate gluing, and directly by clad can wad gluing or to invade glue compound through pressurizeing; Also can invade glue to honeycomb core jointly with the surface layer wad after add be pressed in compound; Fiber wood cellular board can be that flat board also can be a curved plate.Fiber wood cellular board can be used as the various cell boards of partition panel, table board, furniture-plates, partition panel or the like; Just can extrude various fiber wood cellular doors through adding frame, Jia Mo or adding contiguous block etc.; Become decorative sheet through facing; Also can directly make pallet, furniture parts, hull, container plate, compartment board or the like product: the honeycomb pellet can satisfy the demand of concave-convex curved surface sandwich structure through processing.

The invention has the beneficial effects as follows: the wad cellular board greatly reduces the use amount of timber, and can realize easily decorating with various finish materials, and can be the decorative layer of realizing carrying wood grain through the wad that mills special processing such as shape, sanding as the restricting material of composite intermediate layer cellular board, realized the maximization of material use efficient, realize the manufacturing efficiency maximization, had extraordinary economic benefit and social benefit.
