Device and method for preparing paper and plastic composite plate for steel roll package

Abstract

The invention relates to a device and a method for preparing a paper and plastic composite plate for a steel roll package. A hot press serves as a core, the device is provided with a coiling and recoiling device, a paving device, a cooling device, a coiling device, a mobile trolley, a plate drawing device, a plate cutting device, an automatic stacking device and the like, the working pressure of the hot press, the slide block stroke, the hot pressboard temperature control, the paper and plastic plate movement working speed and the shearing plate specification can be adjusted according to a technical process through hydraulic control, programmable logic controller (PLC) electronic control and frequency conversion control, and a fixed-travel molding technical way of the hot press can be finished. Paper and plastic wastes are changed into a composite plate, the manufacturing cost is relatively low, and the source of the raw materials is wide; and compared with the current paper and plastic (aluminum) composite material which is difficultly separated and reused, the material provided by the invention is convenient to reclaim and reuse and can be also naturally degraded after being used and the environmental protection is facilitated.

Description

technical field [0001] The invention relates to a production device and method of a paper-plastic composite board with waterproof and antirust functions, in particular to a production technology of a waterproof and antirust packaging board used for packaging metal materials such as steel plates and coils. Background technique [0002] At present, when the steel coils and steel plates produced in the steel industry are packaged at the factory, they are mostly made of thin steel plates or plastic plates. The above two packaging materials have been used in the steel industry for many years. However, since steel and plastic are non-renewable resources, the price of these materials has increased significantly in recent years, resulting in a sharp increase in packaging costs. In addition, thin steel plates are used as product packaging materials, which are prone to rust after being stored for a certain period of time. The plastic board is easily deformed and brittle due to the in...
