Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis grid processing, in particular to an online grid cutting device. Background Art

[0002] The principle of reverse osmosis is to use sufficient pressure to separate the solvent in the solution through reverse osmosis. Because it is opposite to the direction of natural osmosis, it is called reverse osmosis. According to the different osmotic pressures of various materials, the reverse osmosis method with a pressure greater than the osmotic pressure can be used to achieve the purpose of separation, extraction, purification and concentration. Reverse osmosis has the characteristics of simple operation, strong adaptability and wide application range. Its application range in water treatment is expanding day by day, and it has become one of the important methods of water treatment technology. The roll element is formed by bonding the semipermeable membrane, the guide layer and the grid on the central tube in a certain arrangement according to the principle of reverse osmosis. The raw water enters the grid layer from one end of the element. When passing through the grid, under the action of external pressure, a part of the water penetrates into the guide layer through the holes of the semipermeable membrane, flows along the waterway of the guide layer to the discharge holes of the central tube, and is discharged through the central tube. The remaining part is discharged from the other end of the grid. As an important equipment element in the current water treatment equipment, the grid usually needs to be cut into the required width during its processing and manufacturing process. The existing grid cutting process is mainly carried out by a cutting device.

[0003] The slitting device includes an unwinding roller for unwinding the grid and a winding roller for winding the grid, a mounting shaft is arranged between the unwinding roller and the winding roller, and a cutting knife for slitting the grid is arranged on the mounting shaft. For example, the patent document with application number 201420820805.6 discloses a slitting machine, but the device cannot conveniently adjust the width of the cut grid according to the demand. In view of this, we propose a grid online slitting device with adjustable cutting width. Summary of the invention
