A shift frame 22 located outside the translation connecting frame 25 is arranged on the top of the insertion bin 24, and a pressure roller 20 is arranged at the bottom of the shift frame 22. A trapezoidal blocking plate 18 is installed on the side of the support bracket 19 close to the placement table 1, and a connecting frame 15 is connected to the output end of the telescopic cylinder 9. An L-shaped movable plate 17 matching the trapezoidal blocking plate 18 is arranged on one side of the connecting frame 15. The support bracket 19 is divided into a horizontal section 191 and an inclined section 192. One-way shifting units located above the support bracket 19 are arranged on both sides of the placement table 1.

[0023] In this embodiment: when the U-shaped pressure plate 4 presses one end of the diaphragm and then starts the telescopic cylinder 9, the L-shaped movable plate 17 is separated from the trapezoidal blocking plate 18 through the operation of the telescopic cylinder 9.

When the latch 23 is separated from the top of the inclined section 192, the third return spring 28 pushes the plug-in bin 24 to move downward under the action of the elastic restoring force, so that the pressure roller 20 moves down to the top of the diaphragm, so that the pressure roller 20 presses the diaphragm or the water purification net during the contraction of the telescopic cylinder 9, so as to discharge the air between the diaphragm and the water purification net, so as to reduce the winding frame 2 when winding the stacked diaphragms and water purification nets. When the latch 23 is separated from the swinging inclined rod 21, the swinging inclined rod 21 will be restored under the action of the torsion spring 31. As the L-shaped movable plate 17 moves, one end of the latch 23 is in contact with the trapezoidal blocking plate 18. At this time, the trapezoidal blocking plate 18 will squeeze the latch 23, so as to separate the latch 23 from the L-shaped movable plate 17. When the first slider 26 is in the state of being extended, the first slider 26 will drive the latch 23 to restore and move under the action of the elastic restoring force of the second return spring 6. At this time, the positioning inclined rod 21 is limited by the second stop block 30 and the first stop block 29, so that the latch 23 moves to the top of the supporting cross bar 16 along the positioning inclined rod 21. When the second return spring 6 is fully extended, the latch 23 is separated from the supporting cross bar 16, and at the same time, it falls to the top of the inclined section 192 under the action of the third return spring 28, so as to realize the one-way pressing of the pressure roller 20 on the diaphragm or the water purification network, so as to prevent the pressure roller 20 from pushing the diaphragm or the water purification network when resetting; S4: Move the water purification net placement plate 39 to one side of the U-shaped pressing plate 4 by the operation of the alternating feeding member, pull the U-shaped pressing plate 4, and place one end of the water purification net on the water purification net placement plate 39 under the U-shaped pressing plate 4, and then release the U-shaped pressing plate 4. At this time, the U-shaped pressing plate 4 will press one end of the water purification net through the first return spring 3, and then lay the water purification net on the diaphragm by the operation of the alternating feeding member and the pressure-connecting exhaust member; S5: The membrane sheets and the water purification net can be stacked repeatedly in this way, and then the membrane is rolled up by the operation of the winding frame 2.
