The cutting mechanism 5 performs a pressing process on the cutting quantity and the two sides of the reverse osmosis membrane according to the size of the reverse osmosis membrane to avoid the reverse osmosis membrane from shifting during the processing. An adjusting mechanism 10 is arranged directly below the cutting mechanism 5. The adjusting mechanism 10 adjusts the activity range and height of the cutting device according to the size of the reverse osmosis membrane to complete the transverse cutting of the reverse osmosis membrane.

[0023] In this embodiment, the adjustment mechanism 10 includes a transverse bracket 4, a ball screw 6, a device case 7, a motor 8 and an electric telescopic rod 16. The transverse bracket 4 is arranged directly above the device base 1. The motor 8 is connected to one side of the transverse bracket 4. The output end of the motor 8 is connected to the ball screw 6. The outer side of the ball screw 6 is connected through the device case 7. The device case 7 is connected through the transverse bracket 4. The electric telescopic rod 16 is arranged inside the device case 7. The device is positioned at equal intervals through the transverse bracket 4 to complete the equal-interval cutting process of the membrane.

[0024] In this embodiment, the equipment box 7 is connected to the top of the processing bracket 9 by an electric telescopic rod 16 disposed inside, and the processing bracket 9 is vertically lowered by the electric telescopic rod 16 to complete the vertical edge pressing process of the reverse osmosis membrane.

[0025] In this embodiment, the cutting mechanism 5 includes a processing bracket 9, a pressure wheel 11, a knife seat 12, a cutting blade 13, a slider 14, and a slide groove 15. The pressure wheels 11 are symmetrically arranged on both sides of the processing bracket 9. A slide groove 15 is opened at the bottom end of the processing bracket 9. The bottom end of the slide groove 15 is connected to a slider 14. The bottom end of the slider 14 is connected to the knife seat 12. The bottom end of the knife seat 12 is connected to the top of the cutting blade 13. The slider 14 is vertically positioned by the slide groove 15 to complete the set spacing adjustment.

[0026] In this embodiment, the processing support 9 is connected to the guide groove 2 through a symmetrically arranged pressing wheel 11 with the same diameter, and the pressing wheel 11 arranged at the bottom end of the processing support 9 is used to vertically press and position the reverse osmosis membrane.

[0027] In this embodiment, the cutting blade 13 is connected to the bottom end of the slider 14 via the blade holder 12 disposed at the top, and the distance is adjusted via the slider 14 disposed at the top of the cutting blade 13 to complete the adjustment control of the equipment.

[0028] The practical application of this reverse osmosis membrane production reciprocating film cutting machine includes the following work contents:

[0029] Step 1: The operator first installs multiple groups of sliders 14 inside the slide 15 according to the size of the reverse osmosis membrane and the size that needs to be cut at one time, and controls the spacing of the cutting blades 13 according to the cutting requirements of the reverse osmosis membrane, and then connects the sliders 14 and the slide 15 through the fastening holes provided with screws, thereby completing the connection of the sliders 14, and connecting the sliders 14 to the top of the knife seat 12, and vertically fixing the cutting blades 13 of corresponding sizes through the knife seat 12, thereby completing the installation of the setting;

[0030] Step 2: The operator lays the reverse osmosis membrane stored on the roller on the surface 1 of the equipment base, aligns the edge of the reverse osmosis membrane and the equipment base 1, and then opens the electric telescopic rod 16, and drives the processing support 9 and the pressing wheel 11 to vertically descend through the electric telescopic rod 16, so that the pressing wheel 11 is inserted into the inside of the guide groove 2, and the two sides of the reverse osmosis membrane are pressed and fixed, and at the same time, the cutting blade 13 is in contact with the surface of the reverse osmosis membrane;

[0031] Step 3: The operator turns on the motor 8, drives the ball screw 6 to rotate, drives the equipment box 7 to move horizontally through the ball screw 6, and adjusts the position of the equipment box 7. At the same time, the equipment box 7 is laterally displaced on the horizontal bracket 4 through the through holes set on both sides, and then the reverse osmosis membrane is transversely cut by the cutting blade 13 set under the processing bracket 9. At the same time, the pressing wheels 11 set on both sides press the two sides of the reverse osmosis membrane to prevent the reverse osmosis membrane from displacement;

[0032] Step 4: When cutting different types of reverse osmosis membranes, you can choose to switch different direct pressing wheels 11 and cutting blades 13 according to your needs. When the reverse osmosis membrane is cut by the cutting blade 13, the cutting blade 13 is vertically lowered by the electric telescopic rod 16, and the pressure wheel 11 moves synchronously in the guide groove 2 to complete the material pressing process.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
