Description
Technical Field
The invention relates to the technical field of composite structural plate processing, in particular to processing equipment and a processing technology of a composite structural plate in a compression molding plate.
Background
The wood-bamboo straw composite plywood is generally prepared by compounding a panel layer, a core layer and a substrate layer, wherein the panel layer is a wood-bamboo composite material layer formed by combining wood veneers, bamboo mats and bamboo curtain veneers, the core layer is a straw board, and the substrate layer is another wood-bamboo composite material layer. The wood-bamboo composite material layer is a high elastic modulus and wear-resistant layer. The veneers of the wood-bamboo recombination material layer are wood veneers, bamboo curtains and bamboo mat veneers which are dried for one time and are applied with adhesive. The glued bamboo curtain and the bamboo mat single board are dried (glued) for the second time, and then assembled with the straw board, and the artificial board is manufactured after hot pressing. The wood and bamboo materials are attractive in texture, the performance of the wood and bamboo materials is complementary with that of the straw board, and the board has good mechanical property and natural attractive and elegant appearance, and can be applied to manufacturing of floors, container bottom plates and the like.
The hot pressing can be that the board of the core layer is first hot pressed for the first time, and then the core layer is added with the panel layer for the second hot pressing; for example, patent document CN100491086C entitled "composite container floor using structural chipboard as core material and method for manufacturing the same". Referring to the patent document, the manufacturing process of the straw wood bamboo composite container bottom plate with the straw plate as a core layer material comprises the following steps: firstly, manufacturing or purchasing a straw board produced by a professional factory, and then cutting edges of the straw board according to the length and the width of the process requirement, wherein the straw board is used as a core layer; selecting or manufacturing a wood-bamboo recombination material layer, and sequentially performing primary drying, adhesive application and secondary drying (adhesive drying) on a veneer of the wood-bamboo recombination material layer; then, gluing and assembling the two sides of the cut straw board, and then performing hot press molding with the wood-bamboo recombinant material layer after secondary drying; namely, when the straw material is made into straw boards, primary hot pressing is carried out, and secondary hot pressing is carried out on the straw boards and the wood-bamboo recombination material layer assembly. The defects of the process method are as follows: firstly, a pre-cured layer is generated during production of the straw board, surface sanding is required before delivery, and packaging and delivery can be performed after one-time cutting; secondly, the straw board is assembled after reaching a secondary processing plant for attaching wood and bamboo veneers, and the composite structural board obtained after hot pressing is cut, namely, the straw board is subjected to secondary cutting to form a product delivery, and a large amount of materials are wasted after primary sanding and secondary edge cutting of the straw board; thirdly, the straw is firstly subjected to hot-press molding to form a straw board, and the straw board is subjected to secondary hot-press after being assembled, so that the comprehensive hot-press time of the secondary hot-press is long, and a large amount of heat source resources are wasted; fourthly, the straw board participating in the secondary hot pressing causes the physical and mechanical properties of the straw board to be reduced by 10 percent or more, and simultaneously, the phenomenon that the dipping and stripping indexes of the core straw board product are unqualified is extremely easy to cause.
Or the panel layer and the core layer are subjected to one-time hot pressing after assembly; for example, patent document CN 106313202B, a composite structural board of a wood-bamboo composite material with a fiber unit layer. The composite structure board prepared by the assembly solves the problems of secondary cutting and pre-curing of the straw board and waste of heat energy resources, and improves the physical and mechanical properties of the board. However, the assembled plate, especially the bamboo curtain, is a flexible and rigid complex, and more man-made and material problems are considered during assembly, so that the problem of insufficient allowance of the processing edge of the product is prevented. Because the design processing allowance is larger, the waste of the resources of the overall straw and bamboo materials is larger, and the waste reaches more than 8 percent. Meanwhile, the thickness of the bamboo-wood veneer of the assembled body is greatly changed, and the bamboo-wood veneer is often a curved surface with a middle high and two sides collapsing, so that the corrugated crack appears on the core layer straw fiber assembled body after the pre-pressing and hot pressing stress, and the physical and mechanical properties of the board are reduced. As shown in fig. 1, in the existing production assembly, a right-angle positioning plate is used for manually positioning the plate, the other two sides of the plate are abandoned, the paving deformation of the two sides of the paving material is easy to cause, a large machining allowance is needed to meet the later plate edge shearing, and particularly the plate comprises a bamboo curtain which is soft and more easily causes the paving deformation. As shown in fig. 2, the height of the right-angle positioning plate is fixed, when the thickness of the assembled plate is higher than that of the right-angle positioning plate, the plate is easily positioned inaccurately by manual pavement, the edges of the assembled plate are uneven, and the shearing quantity of the plate edges at the later stage is increased.
Therefore, how to reduce the reserved amount of plate edge shearing on the basis of reducing one hot pressing process and the comprehensive hot pressing time, thereby reducing the consumption of raw materials and energy sources and reducing the production cost is a technical problem to be solved in the field.

The paving of the straw blank layer and the wood-bamboo composite heavy material layer is completed in the lifting control blank forming die 3 in the shape of a Chinese character 'hui'. Firstly, a lower wood-bamboo recombination material layer 91 is laid in a back-shaped liftable control blank assembling die 3 on a backing plate 5, a die electromagnet 36 is powered, and the back-shaped liftable control blank assembling die 3 is tightly attached to the backing plate 5; then using a straw blank layer paving machine 8 to convey the pre-pressed straw blank layer 92 and paving the pre-pressed straw blank layer 92 into the lifting control blank mould 3 in the shape of a Chinese character 'hui', and positioning and paving the pre-pressed straw blank layer 92 above the lower wood-bamboo recombination material layer 91; then, the upper wood-bamboo recombination material layer 93 is paved on the back-shaped liftable control blank assembling die 3, and finally, the decoration paper 94 is paved, so that the assembling process is completed.
The top positioning baffle 331 and the upper plate 31 of the blank mold 3 are automatically raised along with the height of the upper wood-bamboo recombination material layer 93, so that the edge positioning of the upper wood-bamboo recombination material layer 93 is always controlled within the specified optimal interval position. First, the plurality of lifting and lowering devices 35 are lowered below the position of 40 mm at the lowest position, the inner peripheral U-shaped groove 3321 is closed with the top positioning baffle 331, and the outer peripheral U-shaped groove 3381 is closed with the top support 337. The motion control assembly then pushes the push rod, in conjunction with fig. 5: after pushing 1-2 mm to the left, the top positioning baffle 331 and the bottom positioning baffle 332 are stopped to move 1-2 mm to the left, and the top positioning baffle and the bottom positioning baffle exceed the lower flat plate in the shape of Chinese character Hui by 1-2 mm. And (5) paving the longitudinal wood veneers, the transverse wood veneers, the longitudinal bamboo curtains, the wood veneers and other assembly materials. After the number of layers is laid, the laying of the straw blank layer 92 is started. After the straw blank layer 92 is paved, the plurality of lifting adjusting devices 35 start to stably rise under the action of the air cylinders, the upper plate 31 in the shape of a Chinese character 'hui' starts to rise, the top positioning baffle 331 is stopped after exceeding 1-2 cm of the straw blank layer, and then the top positioning baffle 331 moves leftwards by about 2 mm under the drive of the top movable control component 335 until the edge side wall of the top positioning baffle 331 and the edge side wall of the bottom positioning baffle 332 are on the same vertical line. The laying of the upper wood bamboo composite layer 93 is then continued, for example: wood veneers, longitudinal bamboo curtains, transverse wood veneers, longitudinal wood veneers, decorative papers, and the like. When the upper wood-bamboo recombination material layer 93 is paved, the edges of the upper plate 31 and the top positioning baffle 331 which are always in the shape of a Chinese character 'hui' are automatically increased by 1-2 cm along with the increase of the upper wood-bamboo recombination material layer 93; and (5) finishing the paving work.

At least four inner side auxiliary cylinders (air cylinders) drive the inner side pressing plates 16 to descend to the composite structural plate blank layer 9 and press the inner side pressing plates when the prepressing machine 1 is in the end stage of prepressing, so that resistance of the composite structural plate blank layer 9 due to prepressing deformation can be overcome when the lifting control blank mold 3 in the shape of a Chinese character 'Hui'. When the blank mold 3 of the lifting control group in the shape of a Chinese character 'Hui' rises to the state that the lower plate 32 in the shape of a Chinese character 'Hui' is completely separated from the blank layer 9 of the composite structural plate, at least four inner side auxiliary cylinders (air cylinders) start to quickly lift the inner side pressing plate 16 to an initial working position, so that the inner side pressing plate 16 is sleeved on the main pressing plate 13 of the preformer 1, and the lower surface of the inner side pressing plate 16 and the lower surface of the main pressing plate 13 are kept on the same plane; waiting for the next pre-pressing procedure. Then, the pre-pressed composite structural board blank layer 9 is transported out of the preformer 1 along with the backing board 5 and then transported to a board feeding bracket of the hot press 2. Subsequently, the outer side auxiliary cylinder (air cylinder) of the preformer 1 drives the outer side pressing plate 15 to put down the blank mold 3 of the lifting control group in a shape like a Chinese character 'hui' to the plate transferring device 14, the pre-pressing electromagnet 151 at the top end of the pressing plate is powered off, and the outer side auxiliary cylinder (air cylinder) of the preformer 1 lifts the outer side pressing plate 15 to the initial working position. The blank mold 3 is transported to the discharging plate conveyer 7 by the plate transfer device 14. The mould lifting machine 4 lifts the lifting control blank mould 3 in the shape of a Chinese character 'hui' from the discharge plate conveyor and conveys the blank mould to the backing plate 5 at the initial paving position to carry out paving and assembling work of the next plate.
