Description
Technical Field
The invention relates to the technical field of honeycomb core plate manufacturing, in particular to a banding device and a banding method for a plastic honeycomb core plate.
Background
Currently, the plates on the market can be divided into two types, solid plates and hollow plates in terms of structural form. As one type of hollow plate, the honeycomb plate is mainly formed by compounding a face plate, a back plate and a honeycomb core; the panel and the backboard are arranged in parallel, and the honeycomb core is arranged between the panel and the backboard. The honeycomb panel is widely applied to various fields such as building curtain walls, rail trains, aerospace industry, ship industry and the like because of the characteristics of light weight, high strength and the like.
The finished honeycomb board is required to be subjected to edge sealing by edge sealing strips, and especially the edge sealing process of the plastic honeycomb board is always a research hot spot in the field. In the existing edge sealing technology of the plastic honeycomb plate, a method of directly bending a panel and a method of pasting glue are mostly adopted.
The method for directly bending the panel is mainly applied to the edge sealing of the right-angle edge, and when the four sides of the honeycomb plate are arc-shaped, the corners are chamfer angles or fillets and the like, the method cannot be used well, so that the method has obvious limitations, and the honeycomb plate manufactured by the method has poor post-processing property and cannot be subjected to secondary molding.
The method for pasting glue is that a foaming strip or a sealing strip is adopted to directly paste the edge of the honeycomb panel through glue and the sealing surface is combined for sealing; in the method, the adhesive is poor in adhesion fastness, especially for PP (polypropylene) plastic honeycomb plates, so that after long-time use, the edge sealing surface, even the foaming strip or the edge sealing strip, is easy to fall off; in addition, the edge sealing surface and the foaming strip are required to be produced through separate production lines; therefore, the method has the defects of complex process, high cost and infirm.
In summary, a new edge sealing process is urgently needed to enable plastic honeycomb panels to be used more widely.
