Description

Technical Field

[0001] This utility model relates to the field of shielding co-extruded film technology, specifically a shielding co-extruded film surface coating device. Background Technology

[0002] Co-extruded film is a multi-layered plastic film made from different plastic materials through a co-extrusion process. Typically, co-extruded film consists of three parts: a structural layer, an adhesive layer, and a functional layer. The structural layer refers to the substrate of the co-extruded film, usually made of materials such as polyethylene (PE) or polypropylene (PP). Their physical properties determine the strength and stability of the co-extruded film. Co-extruded film coating usually requires dust-free, constant temperature and humidity conditions, necessitating novel shielded co-extruded film surface coating devices.

[0003] The existing patent, CN216025865U, entitled "A Thin Film Surface Coating Device," discloses a thin film surface coating device, relating to the field of thin film coating technology. It includes a support base, with a first support plate and a second support plate fixedly installed on the upper surface of the support base near one corner. A first moving plate and a second moving plate are also installed on the upper surface of the support base near the other corner. A moving mechanism is provided on the support base. Middle vertical plates are fixedly installed on the upper surface of the support base near the middle of both sides. A coating mechanism is provided between the two sets of middle vertical plates. The coating mechanism includes two sets of coating rollers, with a tube shaft movably connected to both ends of each set of coating rollers. This invention features rapid double-sided coating, improving work efficiency, and allows for convenient adjustment of the shaft according to the film width, preventing film deviation during winding. It is suitable for coating films of different widths.

[0004] The aforementioned device has a fast double-sided coating function, which improves work efficiency and allows for convenient adjustment of the shaft according to the width of the film. However, because the co-extruded film is a flexible material, it requires flexible coating and is easily damaged when subjected to hard extrusion, which cannot well meet people's usage needs. In view of the above situation, technical innovation is carried out on the basis of the existing surface coating device. Utility Model Content

[0011] Furthermore, a rotating plate is installed around the guide roller, and the rotating plate is threadedly connected to the guide roller. Rotating the rotating plate changes its position to adapt to the width of the co-extruded film.

[0012] Furthermore, a top cover is installed on the top of the outer shell, and the top cover is rotatably connected to the outer shell, with an observation window reserved on the top cover.

[0013] Furthermore, a humidifier is installed at the rear end of the inner shell, and a heater is installed on the left side of the humidifier. The humidifier and the heater ensure that the temperature and humidity inside the shell are at a suitable level, thus ensuring good coating quality.

[0014] Compared with the prior art, the beneficial effects of this utility model are: opening the top cover and rotating the rotary plate to change the position to adapt to the width of the co-extruded film, and the humidifier and heater ensure that the temperature and humidity inside the shell are at a suitable level, ensuring good coating quality.
