Technical Field

The invention relates to a processing and processing technology of a bamboo board plate, in particular to hot-pressing equipment and a hot-pressing technology of a composite bamboo board.

Background

Longitudinally cutting bamboo into thin bamboo strips, and processing the bamboo strips into a thin bamboo strip curtain; rolling the remainders (such as board skins, wood cores and other waste materials) or small-diameter woods after wood making and rotary cutting into net-shaped wood bundles, and sewing the net-shaped wood bundles into a wood bundle curtain; the method comprises the steps of using rotary-cut wood veneers and the like as constituent units, respectively drying and gluing, then using wood bundle curtains as core layers, bamboo skin curtains as inner layers, using wood veneers as surface layers, and optionally a layer of impregnated paper on the surface layers to form a slab with a symmetrical layered structure, and synthesizing the bamboo-wood composite board through hot-pressing glue. At present, most of common hot presses for hot pressing of composite bamboo boards press multiple layers of bamboo boards together after gluing, and the pressing process needs to be carried out

Therefore, the hot press is inconvenient to work, and the stability of the hot press is poor, so that the hot pressing effect is influenced; referring to fig. 1, most of the currently common bamboo board materials are composed of a facing material, a bottom material and a middle material, and wrapping heads are arranged on two sides of the middle material. Moreover, the existing common glue has irritation and toxicity, and can affect the health of workers. Glue brushing can be carried out on each bamboo strip in the processing process, and a large amount of lubricating oil is needed during the operation of the glue brushing machine to ensure the operation of the glue brushing machine. Meanwhile, in the processing process, the number of the fabric and the bottom material is counted manually, and the phenomenon of few strips of the fabric can occur once errors occur. At present, each press needs three plate-assembling workers, so that the efficiency of the workers is low, and the labor intensity is high; meanwhile, the successfully pressed board needs to be manually stripped, which can not affect the use and the appearance of the board.

Disclosure of Invention

The invention aims to provide hot-pressing equipment and a hot-pressing process for a multilayer composite bamboo board aiming at the defects and shortcomings of the prior art, which can greatly reduce the using amount of glue and improve the efficiency of workers, and 1-3 glue presses can be operated in each work; and the edge of the product is more beautiful.

In order to achieve the purpose, the hot pressing equipment for the multilayer composite bamboo board comprises a base 1, a pressing bottom plate 2, a pressing upper cover plate 3, a pressing plate 4 and a vacuumizing mechanism 5, wherein the pressing bottom plate 2 is fixedly arranged at the upper part of the base 1, the pressing upper cover plate 3 is sleeved at the upper part of the pressing bottom plate 2, the pressing plate 4 is arranged at the inner side of the pressing upper cover plate 3, and a pressing plate shaft 41 of the pressing plate 4 penetrates through the middle part of the pressing upper cover plate 3 and extends out from the upper part; the bottom of the pressing plate 4 is provided with a plurality of pressing heads 42, and the vacuumizing mechanism 5 is arranged on one side of the pressing upper cover plate 3.

The upper part of the pressing bottom plate 2 is provided with a groove 21. The pressed plate can be better kept sealed when being placed in the groove 21, and a better pressing effect can be achieved.

The periphery of the pressing upper cover plate 3 is provided with a downward edge 31, and the edge 31 is sleeved at the extension part of the pressing bottom plate 2.

The hot pressing process of the multilayer composite bamboo board comprises the following steps: before pressing, a vacuum pumping mechanism 5 is used for pumping out partial air from the interior of the upper cover plate to form negative pressure between the upper cover plate 3 and the pressing bottom plate 2; respectively pressing the four outer joints of the fabric 6, the bottom material 7 and the middle material 8 by using a single-board press; the plurality of middle materials 8 are spliced in order, and glue is brushed on the middle materials when the middle materials 8 are spliced; the two sides of the fabric 6, the bottom material 7 and the middle material 8 are spliced with the toe cap 9.

The fabric 6 and the backing material 7 are strip fabrics. The fabric 6 and the backing material 7 are tightly pressed by internal negative pressure in the pressing process with the middle material 8, and are not easy to generate and crack in the later use due to the internal negative pressure.

The plus material 6 and the backing material 7 are pressed by the method, and the plus material 6 and the backing material 7 do not need to be counted because of the head wrapping frame and are directly spliced. Meanwhile, in the pressing process by the method, the glue is only needed to be brushed on the middle materials, so that the using amount of the glue can be greatly reduced, the working environment of workers is improved, and the health of the workers is ensured.

The board pressed by the invention is mainly used for manufacturing a household chopping board for cutting vegetables, the side edge of the chopping board manufactured by the original process method is provided with three layers of boards, the boards are easy to crack and rise in the using process, particularly, corners are easy to crack after falling and falling, the cracking cannot be recovered, and the cracking cannot be recovered even if the boards are bonded by glue; the chopping block made of the novel method is not easy to crack because the whole plate is arranged on the side surface, and the whole plate is not easy to crack even if falling or falling, so that the service life of the product is greatly prolonged, and the use experience of a user is improved.
