Edge covering method and device of plastic honeycomb sandwich panel

The invention relates to an edge covering method and device of a plastic honeycomb sandwich panel. An edge sealing region is arranged outside a product outline; an upper surface skin is removed in the edge sealing region; a high-temperature part is used for smelting from top to bottom to remove a honeycomb and soften a lower surface skin; then the softened lower surface skin is folded over to realize edge covering of a product. By adopting an edge covering manner, the edge of the product is full and straight and the edge strength of the product is increased; the edge sealing difficulty of a PPHC (Polypropylene Honeycomb) material is solved and application of a PPHC to a spare tire cover plate is propelled. 本发明涉及种塑料蜂窝夹芯板的包边方法及装置，通过在产品轮廓之外设置封边区，在封边区内，去除上表皮，用高温部件从上向下熔化去除蜂窝并软化下表皮，然后翻折被软化的下表皮，实现产品的包边。这种包边方式，产品的边缘丰满、挺实，增加了产品的边缘强度，解决了PPHC材料边缘封闭的难题，会推动PPHC在备胎盖板上的应用。
