Description

Technical Field

[0001] The utility model relates to the technical field of new polymer packaging materials, in particular to a raw material mixing device for the film blowing process of plastic protective films. Background Art

[0002] PE protective film is a very simple high-molecular organic compound and also a very widely used high-molecular material in the world. The PE protective film is based on a special polyethylene (PE) plastic film and is divided into high-density polyethylene protective film, medium-density polyethylene, and low-density polyethylene according to different densities. It has soft properties, good adhesion, is easy to peel off, and has no residual glue after peeling. In the production process of plastic products, the film blowing process is a key link and is widely used in the production of plastic protective films, packaging materials, etc. To ensure the stability of the film blowing process and the quality of the finished product, the uniform mixing of raw materials is particularly important. The production of plastic protective films usually requires precise mixing of a variety of different raw materials, including polyethylene, additives, and colorants, etc. The uniformity of these raw materials directly affects the mechanical properties, transparency, and appearance of the final product. Traditional raw material mixing methods usually rely on manual operation or simple mechanical stirring, with low mixing efficiency and it is difficult to ensure the full fusion between different materials, thus affecting the stability of the film blowing process and the consistency of the product.

[0003] The existing "plastic raw material mixing device for protective film production" with the authorization announcement number of CN220052410U includes a mixing support frame, a separable mixing and stirring device, a raw material mixing box, an anti-caking mixing device, and an anti-leakage cover plate. The separable mixing and stirring device is arranged on the mixing support frame, the raw material mixing box is arranged on the separable mixing and stirring device and is wrapped by the mixing support frame, the anti-caking mixing device is arranged on the raw material mixing box, and the anti-leakage cover plate and the raw material mixing box are in a threaded connection. The utility model belongs to the technical field of protective film production, specifically a plastic raw material mixing device for protective film production, which effectively solves the problem that the fixed mixing box on the market at present leads to poor mixing effect and easy caking. By changing the original fixed mixing box into a rotating type, the mixing efficiency is effectively improved, the production cost is reduced, and at the same time, the problem of raw material caking is avoided.

[0004] The raw material mixing devices in the prior art generally have problems such as low automation degree, uneven mixing, and cumbersome operation. Many devices cannot fully stir the raw materials, resulting in uneven mixing and ultimately affecting the quality of the film blowing process. In addition, traditional mixing devices require frequent manual intervention during operation, increasing the labor intensity and production cost, and it is difficult to achieve rapid and convenient material taking after mixing, reducing the production efficiency. Therefore, we provide a raw material mixing device for the film blowing process of plastic protective films. Content of the Utility Model
