Abstract
The invention discloses a method for manufacturing an environmental-friendly molded tray, which comprises the following steps: (1) raw material and wood shaving preparation; (2) glue mixing; (3) pavement and hot-pressing; and (4) edge treatment. According to the method disclosed by the invention, the whole manufacturing process is carried out under the conditions of high temperature and high pressure, so that any residual insect and fungus in wood are killed; and meanwhile, since the wood product is high in intensity, any other inserts can be prevented from newly propagating and intruding in the wood product.
Description
Technical field
The present invention relates to a kind of forming method of pressing, specifically, relate to a kind of manufacture method of environmental protection molded tray.
Background technology
In day by day business-like today, logistics field develops fast and efficiently, and pallet is as important physical distribution apparatus, is mechanized handling, the instrument that transports goods, change static goods the carrier of dynamic goods into, so pallet plays irreplaceable effect in the modern logistics field.Pallet of the prior art adopts the timber manufacturing to form mostly, wastes a large amount of forest reserves, and in the timber insect can in the pallet of making, continue breeding, again invade, thereby affect the quality of pallet.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of manufacture method of saving cost, high-quality environmental protection molded tray.
Its technical scheme is as follows:
A kind of manufacture method of environmental protection molded tray may further comprise the steps:
(1) raw material and wood shavings preparation: select the stalk that does not have soil or adopt light wood, shaving shape, long 50mm, wide 10-20mm, thick 0.5mm, undersized log, brush wood or wood machining residues are removed dust, content of bark≤5%, wood shavings thickness 0.3～0.5mm, timber are sent into the double drum wheel plane and are processed into wood shavings after pulverizer is ground into crushed material, then send into drying machine, the moisture content behind the particle drying is 2～3%;
(2) glue mixing: adopt at a slow speed glue mixer, its rotating speed is≤10 rev/mins, described mixer can be established two spraying systems, in order to apply two kinds of glue that should not mix, the ratio of glue and wood shavings is 1: 3, wood shavings after metering and glue are sent into glue mixer simultaneously, and the wood shavings moisture content after mixing is 8～10%;
(3) mat formation and hot pressing: mat formation and carry out at twice, spread first tray foot and precompressed, repave the planar section of pallet, shallow pin pallet also can once be mated formation, and punch is fixed on the hot press top movable crossbeam, and die is then travelled to and fro between between hot press and the spreading machine, place on the workbench of hot press bottom, be provided with stripper apparatus, the glue mixing wood shavings are mated formation in mould, carry out precompressed, hot pressing gets final product molding after glue solidifies fully;
(4) treating selvedge: be mainly side cut, namely remove the unnecessary overlap of product edges.
Further preferred, glue described in the step (2) is that carbimide and Lauxite mix or phenolic resins and melmac.
Beneficial effect of the present invention: the whole production process of the present invention is carried out under high temperature, high pressure, the any insect and the fungi that remain in the timber have been killed, because wood-based product's density of producing is high, can prevent the again breeding of any other insect and again intrusion simultaneously.This pressing is up-to-date " artificial wooden packaging material " rather than traditional " solid wood packaging material ", its product no longer needs to carry out insect-prevention treatment, in the pallet goods without any the insect that lives, meet ISPM15 (InsternationalStandard for Phytosanitary Measures 15) to the demand of outlet timber packing articles, and through the cycling fatigue experiment in various service lifes, need not carry out any specially treated, just can transport other country to goods.
The specific embodiment
Below in conjunction with the specific embodiment technical scheme of the present invention is described in more detail.
A kind of manufacture method of environmental protection molded tray may further comprise the steps:
(1) raw material and wood shavings preparation: select the stalk that does not have soil or adopt light wood, shaving shape, long 50mm, wide 10-20mm, thick 0.5mm, undersized log, brush wood or wood machining residues are removed dust, content of bark≤5%, wood shavings thickness 0.3～0.5mm, timber are sent into the double drum wheel plane and are processed into wood shavings after pulverizer is ground into crushed material, then send into drying machine, the moisture content behind the particle drying is 2～3%;
(2) glue mixing: adopt at a slow speed glue mixer, its rotating speed is≤10 rev/mins, described mixer can be established two spraying systems, in order to apply two kinds of glue that should not mix, the ratio of glue and wood shavings is 1: 3, wood shavings after metering and glue are sent into glue mixer simultaneously, and the wood shavings moisture content after mixing is 8～10%; Described glue is that carbimide and Lauxite mix or phenolic resins and melmac.
(3) mat formation and hot pressing: mat formation and carry out at twice, spread first tray foot and precompressed, repave the planar section of pallet, shallow pin pallet also can once be mated formation, and punch is fixed on the hot press top movable crossbeam, and die is then travelled to and fro between between hot press and the spreading machine, place on the workbench of hot press bottom, be provided with stripper apparatus, the glue mixing wood shavings are mated formation in mould, carry out precompressed, hot pressing gets final product molding after glue solidifies fully;
(4) treating selvedge: be mainly side cut, namely remove the unnecessary overlap of product edges.
The above only is best mode for carrying out the invention, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses, and the simple change of the technical scheme that can obtain apparently or equivalence are replaced and all fallen within the scope of protection of the present invention.
