Its working principle is based on the liquid separation process driven by a pressure difference, which can retain macromolecular substances and allow small molecular substances and salts to pass through. In order to make the nanofiltration membrane meet the installation requirements, therefore, the nanofiltration membrane needs to be cut to a suitable length before it can be installed in the equipment. However, since the installation conditions of some nanofiltration membranes require leaving part of the filter element at one end for installing the connector, therefore, one end of the nanofiltration membrane needs to be completely cut off (the filter membrane and the filter element of the nanofiltration membrane), and only the filter membrane of the nanofiltration membrane needs to be cut off at the other end.

[0024] like Figure 1 This is a schematic diagram of the structure of the utility model, a nanofiltration membrane component differential cutting device, comprising:

[0025] Rack 1, used for equipment installation;

[0026] like Figure 1 , Figure 2 As shown, the cutting mechanism 2 is used for cutting the nanofiltration membrane.

The lifting drive member 22 is a cylinder. The first cutting knife 23 and the second cutting knife 24 are adjustably arranged on the mounting plate 21, and the first cutting knife 23 and the second cutting knife 24 are arranged in different axes. The first cutting knife 23 is used to cut the filter membrane of the nanofiltration membrane, and the second cutting knife 24 is used to cut the filter membrane and the filter element of the nanofiltration membrane. By arranging the first cutting knife 23 and the second cutting knife 24 in different axes, the nanofiltration membrane can be cut at different radial depths, thereby achieving differential cutting, which can be completed in one processing, thereby improving the processing efficiency. There is a height difference between the first cutting knife 23 and the second cutting knife 24, so that the nanofiltration membrane can be cut at different depths, thereby achieving differentiated cutting.

[0027] As Figure 1 , Figure 2 shown, the cutting mechanism 2 includes guide posts 211 which are fixedly connected to the frame 1. The mounting plate 21 is slidably connected to the guide posts 211, and the guide posts 211 can increase the stability of the movement of the mounting plate 21.

[0028] The cutting mechanism 2 includes a first slide rail 25, a first slider 26 matching the first slide rail 25, a second slider 27 matching the first slide rail 25, a first connecting seat 28 and a second connecting seat 29. The first slide rail 25 is fixedly connected to the mounting plate 21. The first slide rail 25 is slidably connected to the first slider 26 and the second slider 27. The first connecting seat 28 is adjustably connected to the first slider 26. The first cutting knife 23 is rotatably connected to the first connecting seat 28. The second connecting seat 29 is adjustably connected to the second slider 27. The second cutting knife 24 is rotatably connected to the second connecting seat 29. Through the design of the first slide rail 25, the first slider 26 and the second slider 27, the distance between the first cutting knife 23 and the second cutting knife 24 can be adjusted.

[0029] As Figure 1 , Figure 2 shown, a first adjustment hole 281 extending vertically is formed in the first connecting seat 28. A first adjustment bolt 282 is arranged in the first adjustment hole 281. The first adjustment bolt 282 abuts against the first connecting seat 28 and is threadedly connected to the first slider 26. By loosening the first adjustment bolt 282, the first connecting seat 28 can move up and down freely;

[0030] A second adjustment hole 291 extending vertically is formed in the second connecting seat 29. A second adjustment bolt 292 is arranged in the second adjustment hole 291. The second adjustment bolt 292 abuts against the second connecting seat 29 and is threadedly connected to the second slider 27.

[0031] As Figure 1 , Figure 2 shown, and a clamping driving mechanism 3 for fixing the nanofiltration membrane and driving the nanofiltration membrane to rotate.

[0032] The clamping driving mechanism 3 includes a top material driving member 31, a first top material rod 32, a rotation driving member 33 and a second top material rod 34. The top material driving member 31 is a cylinder and is arranged on the frame 1. One end of the top material driving member 31 is in transmission connection with the first top material rod 32. The top material driving member 31 is used to provide power for the first top material rod 32 to approach or move away from the end of the nanofiltration membrane. The rotation driving member 33 is fixedly connected to the frame 1. The output end of the rotation driving member 33 is in transmission connection with the second top material rod 34. The second top material rod 34 is used to abut against the end of the nanofiltration membrane. The first top material rod 32 and the second top material rod 34 are coaxially arranged. The rotation driving member 33 is a motor.

[0033] The clamping drive mechanism 3 includes a second slide rail 35 and a third slider 36 that matches the second slide rail 35. The second slide rail 35 is fixedly connected to the frame 1, the second slide rail 35 is slidably connected to the third slider 36, and the third slider 36 is fixedly connected to the blanking drive member 31.

[0034] Place the nanofiltration membrane to be cut between the first blanking rod 32 and the second blanking rod 34. The blanking drive member 31 is activated to make the first blanking rod 32 approach the nanofiltration membrane until the first blanking rod 32 abuts against one end of the nanofiltration membrane, and the second blanking rod 34 abuts against one end of the nanofiltration membrane, completing the clamping and fixing of the nanofiltration membrane. The rotation drive member 33 is activated to make the nanofiltration membrane rotate, and the lifting drive member 22 is activated to make the first cutting knife 23 and the second cutting knife 24 descend and approach. When the first cutting knife 23 and the second cutting knife 24 contact the nanofiltration membrane, the cutting of the nanofiltration membrane is realized by the rotation of the nanofiltration membrane. Since the heights of the first cutting knife 23 and the second cutting knife 24 are different, one end of the nanofiltration membrane can be completely cut off, and a filter element is left at the other end, making the filter element protrude from the nanofiltration membrane.
