The surface of the inner abutment plate 13 is provided with an anti-slip groove, and it abuts against the inner wall of the filter membrane core tube 8. When the internal threaded tube 5 is rotated, the internal threaded tube 5 will move on the surface of the threaded column 3, and at the same time, it can drive the fixed disk 7 to move, so that the inner abutment plate 13 on one side of the fixed disk 7 is inserted into the end of the filter membrane core tube 8. After the threaded rod 11 is manually rotated, the slider 10 will be driven to move inside the slide groove 9, so that the inner abutment plate 13 moves accordingly, and one side surface of the inner abutment plate 13 is provided with an anti-slip groove, so that it abuts tightly against the inner wall of the filter membrane core tube 8, thereby fixing the filter membrane core tube 8.

[0024] Among them, a slide groove 2 15 is provided on the surface of the fixed plate 7, and a slider 2 17 is slidably clamped inside the slide groove 2 15. One end of the slider 2 17 is fixedly connected to a handle 18, and the other end of the slider 2 17 is fixedly connected to a pressure strip 19.

The filter membrane core tube 8 is abutted against each other, thereby fixing the filter membrane core tube 8, which is convenient for winding up the ultrafiltration membrane. In this technology, filter membrane core tubes 8 of different lengths and inner diameters can be matched according to needs, so that the device can wind up ultrafiltration membranes of different sizes. Before winding up the ultrafiltration membrane, the fixed disk 7 is driven to rotate by a driving source to realize the winding of the ultrafiltration membrane. One end of the ultrafiltration membrane needs to be fixed on the surface of the filter membrane core tube 8, and a person holds the handle 18 to lift the slider 17, and then fits the ultrafiltration membrane to the surface of the filter membrane core tube 8. After releasing the handle 18, the elastic force of the spring 20 acts on the slider 17, so that the pressure strip 19 is pressed tightly against the surface of the ultrafiltration membrane, thereby fixing one end of the ultrafiltration membrane on the surface of the filter membrane core tube 8.
