Description

Technical Field

[0001] The utility model relates to the field of membrane material production equipment, in particular to a composite device for membrane production. Background Art

[0002] There are many types of membrane materials, which are widely used in many scenarios. Among them, composite membrane is a product that multiple membranes with different properties are bonded together. The final produced membrane can have multiple characteristics and functions. One of the processes in its production is the composite of multi-layer membranes, which is also the most important step. There are several composite processes, including hot pressing, coating, lamination, and co-extrusion composite processes; the most commonly used is the coating process, among which the most commonly used methods are hot pressing and solvent methods, which has led to many types of membrane composite equipment.

[0003] However, most of the existing equipment on the market are divided into methods, with only hot pressing function or only solvent dissolution coating function. Hot pressing usually requires extremely high temperature and pressure, while solvent dissolution coating easily causes excessive solvent and waste.

[0004] In order to solve the above problems, we have made improvements and proposed a composite device for membrane production. Utility Model Content

[0009] As an optimal technical solution of the utility model, a solvent tank is provided at the bottom end of the solvent coating device, and the top of the solvent tank is connected to the composite solvent tank; a scraper is provided at the bottom of the solvent tank, and the top of the scraper is fixedly connected to the bottom of the outer surface of the solvent tank.

[0010] As a preferred technical solution of the utility model, a seepage port is provided at the bottom of the solvent tank, and the seepage port is located at the bottom center of the solvent tank and connected to the left side surface of the scraper.

[0011] As a preferred technical solution of the utility model, the composite material roller is located on the right side of the solvent coating box; a hot pressing roller is arranged on the top surface of the conveying device, and the hot pressing roller is located on the right side of the composite material roller, and its front and back ends are rotatably connected to the top of the guard plates on the front and back sides of the conveying device, and the bottom of the middle section is in contact with the top surface of the crawler of the conveying device; a motor is arranged on the back of the hot pressing roller, and the rotating shaft of the motor is fixedly connected to the rotating shaft of the hot pressing roller.

[0012] As a preferred technical solution of the utility model, a drying box is arranged on the top surface of the conveying device, and the bottoms of the front and back ends of the drying box are fixedly connected to the top surfaces of the front and back guard plates of the conveying device. An external fan is arranged on the top surface of the drying box, and the bottom surface of the external fan is fixedly connected to the drying box; a hot air blower is arranged inside the drying box, and the top of the hot air blower is fixedly connected to the top surface of the inner wall of the drying box, and is connected to the external fan through a ventilation pipe passing through the through hole on the top of the drying box.

[0013] The beneficial effects of the utility model are as follows: the composite device for film production combines the two processes of solvent composite and hot pressing composite. The solvent tank cooperates with the solvent tank and the seepage outlet to allow the solvent to slowly and evenly seep downward along the scraper. When the conveying device is continuously running, the solvent can be evenly spread on the film surface through the scraper. The pad at the bottom of the crawler is a heated constant temperature type, which can prolong the retention time of the solvent state. The next process is that the composite material roller directly presses the composite film to the surface of the film that has been coated with the solvent. Under the condition of ensuring automation, compared with the conventional coating process, it can greatly reduce the waste of solvent, reduce the splashing of solvent, and relieve the cleaning pressure. At the same time, the hot pressing roller of the hot pressing process added after the composite material roller can further press the film material, make the film material further integrated, and squeeze out excess solvent.
