Problems solved by technology
Although the patent achieves single-sided compounding, the efficiency of double-sided compounding is not high, and there are a lot of glue used, dried and cooled, which leads to a lot of energy waste and secondary pollution due to the use of glue. Thus it is not conducive to environmental protection, and a solution to the tension control problem in the processing process has not been provided.

The invention relates to the field of packaging material compound, and in particular relates to a compound machine specially used for a film. The invention is mainly used to solve the problem that thecompound properties of the packaging material film are unstable. The invention provides the compound machine specially used for the film, and the compound machine comprises a first unreeling unit, asecond unreeling unit, a third unreeling unit, a traction unit, a compounding unit and a reeling unit, the traction unit is provided with a steel roller and a flexible roller, wherein the steel rollerand the flexible roller are rolled oppositely, and the film is subjected to casting pressure when passing between the steel roller and the flexible roller; and the compounding unit is provided with aconstant-temperature heating device and a compounding roller, and the compounding roller is subjected to heating and compounding on the film which is cast by the traction unit. According to the invention, in an application of the compound machine, the film to be treated is subjected to cold roller casting and hot roller compounding to realize no-adhesive and no-solvent compounding of materials such as aluminum-plastic and plastic-plastic, and no curing process is required after compounding, the performance is stable, the finished product can be directly cut off, the environmental protection is achieved, and the production costs can be reduced.
Description
technical field [0001] The invention relates to a packaging material processing machine, in particular to a packaging material composite equipment, in particular to a film-specific composite machine. Background technique [0002] With the expansion of industrial production, packaging materials with various characteristics are often required, such as aluminum-plastic, plastic-plastic, steel-plastic and other composite materials. Adhesives with a chemical formulation ratio, and need to be equipped with special heating and drying equipment for this purpose, and after compounding, it needs to go through a curing process, not only the process is complicated, but also the characteristics of the obtained product are not stable. At the same time, winding control problems are often encountered in the production process of composite films, such as the uncoiling of material rolls or wires, and the winding tension is very important to the quality of the product. If the tension is too la...
