Description

Mechanism of two-stage paper-plastic material pressing to form paper-plastic tableware

This creation provides a two-stage mechanism for pressing paper-plastic tableware into paper-plastic tableware, which is mainly used in the forming method and technical means of shallow tableware such as dinner plates, spoons, and knives and forks.

The molding process of paper-plastic products can be roughly divided into wet pressing molding and dry pressing molding, which are mainly produced by selecting different processes for different products, and there are many products with shallower depth and thinner thickness in paper-plastic products, such as dinner plates and spoons Disposable tableware such as knives and forks; if the wet pressing method is used, the paper-plastic tableware cannot reach a very thin thickness and consumes a lot of electric energy to dry and form; if the dry pressing method is used, it is impossible to produce a smooth surface. A product that is aesthetically pleasing and takes a long time to make; no matter which molding method needs to use a pulping system to make pulp, the pulping system requires a large space and high cost, and the above two molding processes have high time costs and high energy costs. , high space cost and the price of the paper-plastic products made cannot meet the market demand is one of the shortcomings; and generally the dinner plate completed by the above-mentioned molding process needs to be covered with a layer of plastic film on the surface for waterproof or oil-proof, It makes it impossible to decompose after use, which increases the difficulty of recycling, and thus loses the complete decomposition and environmental protection characteristics of paper-plastic products; the products produced have wrinkles on the periphery due to the difference in inner and outer diameters, and do not have a smooth surface. And conforming to the aesthetic feeling is the second lack. Please refer to the conventional paper-plastic products in the eighth and ninth figures. The periphery 61 of the dinner plate 6 is not smooth and the layers are blurred, which is not in line with the aesthetic sense. It is the lack. In view of the lack of conventional paper and plastic products, the author of this work developed it, and developed this creation after many efforts.

The meaning of the "second-order type" mentioned in this creation can be interpreted as not being the most original material, but a paper-plastic product that is completed by using the original wooden material through papermaking technology. The use of products is quite diverse, one of which is flat or roll-shaped pulp boards, and disposable products such as dinner plates, spoons, knives and forks that can also be plasticized, which are called First-order items, these products are interpreted as "first-order items". This creation is a method of renovating and processing first-order items, which is to form what is called "second-order paper-plastic material compression molding paper-plastic" in this article. Mechanism of tableware", the product molded by this creative method is the so-called "second-order article" in this article, and it will be presented first here. This creation is an innovative paper-plastic product molding process based on the previous technology. It uses a first-order article directly made by a paper mill, that is, a flat pulp board, as the original product of this creation method. In other words, there is no longer any The pulping system is then used to make pulp, and the original embryo (that is, the first-order article) is then operated through an intermediate program to moisten and soften the first-order article, and the additive can be passed through the rendering mechanism in the intermediate program, such as : Mechanisms with functions such as spraying, coating, transfer printing or embossing are added to the surface layer of the original embryonic pulp board, and after standing still, it is hot-pressed to shape and cut the frame and other technological means, which can achieve rapid Production, reduced cost, flatter appearance and generally more rigid secondary items, such secondary items may be shallower depth plates, spoons, cutlery or similar cutlery.
