Description
Technical Field
The invention relates to the technical field of paper-plastic product processing, in particular to rotary spraying equipment and a rotary spraying process for a paper-plastic product.
Background
Paper-plastic products, such as various paper-plastic tableware, need to be waterproof and oilproof when in use, and some products also need to prevent the sticking of contents, such as some Chinese food paper lunch boxes, need not stick rice, etc. The purpose of oil resistance is achieved mostly by adding a fluorine-containing oil-proof agent inside in the past, but the fluorine oil-proof agent is harmful to health and is not degradable, and the application of fluorine-containing products in fast-absorption products is prohibited by legislation in China and other countries in the world at present. As the cost of spraying the coating on the surface of the paper-plastic product is lower than that of directly coating a finished product film, various manufacturers are turning to the mode of spraying the fluorine-free coating on the surface to achieve the effects of preventing water, oil and sticking of contents. The paper-plastic product has rough surface and pores, so that the sprayed coating can fully permeate into the pores and form a protective film on a product containing surface (such as the inner surface of the paper-plastic tableware for loading food), and the aims of water resistance and oil resistance can be fulfilled. If the coating does not fully penetrate pores, shrinkage cavities can be generated after drying, oil and water can penetrate through the shrinkage cavities, and the purposes of water resistance and oil resistance cannot be achieved. For this reason, the spraying process must ensure that there is sufficient coating on the surface of the paper-plastic product and sufficient time for the coating to penetrate into the pores.
In the existing spraying process, static spraying is mostly adopted, that is, the paper-plastic product to be sprayed is still in the spraying device or is relatively still on a conveying belt of a spraying tunnel, such as bulletin numbers: CN211436737U utility model. This type of spraying has the following problems: (1) when the carrying surface of the paper-plastic product faces upwards for static spraying, the paint sprayed excessively covers the carrying surface of the paper-plastic product excessively, and the redundant paint can be accumulated to the bottom in the product, so that the paint cannot be uniformly coated on the carrying surface of the product. (2) When throwing the material device through transport mechanism conveying and get rid of the material after the spraying, it is single to get rid of material process rotation rate, can not compromise the even pleasing to the eye on recycle and the spraying surface of coating well: the sprayed surface coating cannot be effectively thrown to be even and flat due to too low speed; too high speed causes the excessive coating to fly around, is not beneficial to recycle, and has low coating utilization rate. (3) Get rid of the material in-process, need the paper product of moulding of a lot of upset, equipment structure is complicated, occupies more factory building space, and be not convenient for maintain, with high costs.
