The composite assembly 5 includes a coating roller 51 and a composite roller 52. The membrane materials released from the bottom reverse osmosis membrane unwinding assembly 1, the first rigid membrane unwinding assembly 2, the second rigid membrane unwinding assembly 3, and the top reverse osmosis membrane unwinding assembly 4 are passed through the composite assembly 5 to form a composite membrane material 7. The feeding assembly 6 includes a first slide rail 61, a first gripper 62, a second slide rail 63, and a... The second gripper 64, the first gripper 62 includes a first gripper cylinder 621 and a first horizontal clamping plate 622 and a second horizontal clamping plate 623 driven by the first gripper cylinder 621, the second gripper 64 includes a second gripper cylinder 641 and a third horizontal clamping plate 642 and a fourth horizontal clamping plate 643 driven by the second gripper cylinder 641; when the first gripper 62 and the second gripper 64 respectively clamp the two sides of the composite film 7, the first slide rail 61 and the second slide rail 63 synchronously drive the composite film 7 to be transported to the subsequent process.

[0039] Specifically, the bottom layer reverse osmosis membrane unwinding assembly 1 releases the reverse osmosis membrane, the first rigid membrane unwinding assembly 2 releases the first rigid membrane, the second rigid membrane unwinding assembly 3 releases the second rigid membrane, and the top layer reverse osmosis membrane unwinding assembly 4 releases the reverse osmosis membrane. The first and second rigid membranes are disposed between the two reverse osmosis membranes and serve as a support layer. The first and second rigid membranes are preferably non-woven fabric layers, such as PP meltblown material, PET spunbond material, etc.

[0040] See Figures 1 to 4The bottom-layer reverse osmosis membrane unwinding assembly 1 includes a first unwinding shaft 11, a first tension adjusting roller 12, and a first laser displacement sensor 13. The reverse osmosis membrane released from the first unwinding shaft 11 passes through the first tension adjusting roller 12 and several rollers before entering the composite assembly 5. The first laser displacement sensor 13 is aligned with the outermost reverse osmosis membrane of the first unwinding shaft 11 and monitors the radius of the reverse osmosis membrane roll in real time, thereby calculating the release length of the reverse osmosis membrane in real time. The first rigid membrane unwinding assembly 2 includes a second unwinding shaft 21, a second tension adjusting roller 22, and a second laser displacement sensor 23. The first rigid membrane unwinding assembly 2 releases the first... After passing through the second tension adjusting roller 22 and several passing rollers, the rigid film enters the composite assembly 5. The second laser displacement sensor 23 is aligned with the outermost layer of the first rigid film on the second unwinding shaft 21 and monitors the radius of the first rigid film roll in real time, thereby calculating the release length of the first rigid film in real time. The second rigid film unwinding assembly 3 includes a third unwinding shaft 31, a third tension adjusting roller 32, and a third laser displacement sensor 33. The second rigid film released from the third unwinding shaft 31 enters the composite assembly 5 after passing through the third tension adjusting roller 32 and several passing rollers. The third laser displacement sensor 33 is aligned with the outermost layer of the second rigid film on the third unwinding shaft 31 and monitors the radius of the first rigid film roll in real time. The radius of the second rigid membrane roll is monitored to calculate the release length of the second rigid membrane in real time. The surface layer reverse osmosis membrane unwinding assembly 4 includes a fourth unwinding shaft 41, a fourth tension adjusting roller 42, and a fourth laser displacement sensor 43. The reverse osmosis membrane released by the fourth unwinding shaft 41 enters the composite assembly 5 after passing through the fourth tension adjusting roller 42 and several rollers. The fourth laser displacement sensor 43 is aligned with the outermost reverse osmosis membrane of the fourth unwinding shaft 41 and monitors the radius of the reverse osmosis membrane roll in real time to calculate the release length of the reverse osmosis membrane in real time. The release length is calculated by monitoring the radius of the second rigid membrane roll through the first laser displacement sensor 13, the second laser displacement sensor 23, and the third laser displacement sensor 43. The optical displacement sensor 33 and the fourth laser displacement sensor 43 ensure the synchronization of the four membrane layers; the first unwinding shaft 11, the second unwinding shaft 21, the third unwinding shaft 31 and the fourth unwinding shaft 41 are all air-expanding shafts, which facilitates the installation and replacement of the membrane rolls; the first unwinding shaft 11, the second unwinding shaft 21, the third unwinding shaft 31 and the fourth unwinding shaft 41 are all installed on one side of the vertical plate 8, which facilitates the installation and replacement of the membrane rolls; the first unwinding shaft 11 is installed at the bottom of the vertical plate 8 and the fourth unwinding shaft 41 is installed at the top of the vertical plate 8, so that the first hard membrane and the second hard membrane are sandwiched between the two reverse osmosis membranes.

[0041] See Figure 2 and Figure 3The working principle of the first gripper 62 and the second gripper 64 is as follows: The first gripper cylinder 621 is installed on the first L-shaped plate 65. The horizontal part of the first L-shaped plate 65 is movably installed on the first slide rail 61. The vertical part of the first L-shaped plate 65 is provided with a first vertical slide rail 651, a first slider 652 and a second slider 653. The first horizontal clamping plate 622 is installed on the first slider 652, and the second horizontal clamping plate 623 is installed on the second slider 653. The first gripper cylinder 621 drives the first slider 652 and the second slider 653 to move closer or further apart, thereby driving the first horizontal clamping plate 622 and the second horizontal clamping plate 623 to clamp or release. On one side of the composite membrane material 7; similarly, the second gripper cylinder 641 is mounted on the second L-shaped plate 66, the horizontal part of the second L-shaped plate 66 is movably mounted on the second slide rail 63, the vertical part of the second L-shaped plate 66 is provided with a second vertical slide rail 661, a third slider 662 and a fourth slider 663, the third horizontal clamping plate 642 is mounted on the third slider 662, the fourth horizontal clamping plate 643 is mounted on the fourth slider 663, the second gripper cylinder 641 drives the third slider 662 and the fourth slider 663 to move closer or further away from each other, thereby driving the third horizontal clamping plate 642 and the fourth horizontal clamping plate 643 to clamp or release the other side of the composite membrane material 7. The purpose of this embodiment is to intermittently provide the four-layer composite membrane 7 stacked together to subsequent processes. The specific steps are as follows: First, the first gripper 62 and the second gripper 64 move along the first slide rail 61 and the second slide rail 63 unloaded (the first horizontal clamping plate 622 and the second horizontal clamping plate 623 release one side of the composite membrane 7, while the third horizontal clamping plate 642 and the fourth horizontal clamping plate 643 release the other side of the composite membrane 7) to one end close to the composite assembly 5. Second, the first gripper 62 and the second gripper 64 close again. The first horizontal clamping plate 622 and the second horizontal clamping plate 623 clamp one side of the composite membrane material 7, while the third horizontal clamping plate 642 and the fourth horizontal clamping plate 643 clamp the other side of the composite membrane material 7. The first gripper 62 and the second gripper 64 clamp the composite membrane material 7 and move along the first slide rail 61 and the second slide rail 63 to the end away from the composite component 5, completing one conveying cycle. The composite membrane material 7 is conveyed in a cyclic manner according to the first step and the second step, so as to convey the composite membrane material 7 to the next process in a fixed length and intermittently.
