Description

Technical Field

[0001] The present invention relates to the technical field of reverse osmosis membrane processing, and specifically relates to a film winding device for reverse osmosis membrane processing and a film winding method thereof. Background Art

[0002] A reverse osmosis membrane roll is an artificial semi-permeable membrane that filters out impurities such as dissolved salts, colloids, microorganisms, and organic substances in a solution by pressurizing the solution and passing the solution through the reverse osmosis membrane to obtain a pure aqueous solution. The reverse osmosis membrane has the advantages of simple process, low energy consumption, good water quality, and no pollution, and is widely used in food, drinking water, medical treatment, etc. The film winding process of the reverse osmosis membrane roll is as follows: One end of the guiding cloth is adhered to the central tube, glue is applied to the other three sides except the side parallel to the central tube, then a layer of membrane sheet is added in the middle of the guiding cloth, glue is applied to the other three sides except the side parallel to the central tube, a layer of clean water net is placed on the membrane sheet, glue is applied to the other three sides except the side parallel to the central tube, and then the membrane sheet is continuously placed, repeating the above process until the required number of layers of each layer of membrane is placed, and finally the film is wound and encapsulated.

[0003] During the process of winding the reverse osmosis membrane, due to the accumulation of membrane sheets and water inlet nets, a large amount of air exists between them, resulting in a relatively high thickness of the stacked membranes. At this time, when winding each layer of membrane, the membrane sheets will be guided and extruded by the central tube, which will increase the winding resistance and easily cause wrinkles during the winding process, thus affecting the flatness of the winding.

[0014] The present invention also discloses a method for winding membranes for reverse osmosis membrane processing. Using the above-mentioned winding membrane device for reverse osmosis membrane processing, it includes the following steps:

[0015] S1: First, install the center tube at one end of the placing table through the winding frame. Then connect one end of the guiding cloth to the center tube, and use an external gluing device to apply glue to the other three sides of the guiding cloth except the side parallel to the center tube.

[0016] S2: Through the operation of the alternate feeding member, move the membrane placing plate to one side of the U-shaped pressing plate. Pull the U-shaped pressing plate, and place one end of the membrane on the membrane placing plate under the U-shaped pressing plate, and then release the U-shaped pressing plate. At this time, the U-shaped pressing plate will press one end of the membrane through the first return spring.

[0017] S3: Then, through the operation of the alternate feeding member and the pressing and connecting and exhausting member, lay the membrane on the guiding cloth. During this process, make the guiding cloth and the membrane fully adhere through the pressing and connecting and exhausting member. Then use an external gluing device to apply glue to the other three sides of the membrane except the side parallel to the center tube.

[0018] S4: Move the water purification net placement plate to one side of the U-shaped pressing plate through the operation of the alternating feeding member, pull the U-shaped pressing plate, place one end of the water purification net on the water purification net placement plate under the U-shaped pressing plate, and then release the U-shaped pressing plate. At this time, the U-shaped pressing plate will press one end of the water purification net through the first return spring. After that, lay the water purification net on the diaphragm through the operation of the alternating feeding member and the pressure-connecting and exhausting member;

[0019] S5: Repeat the above steps to stack the diaphragm and the water purification net, and then perform film winding through the operation of the winding rack.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting the pressure-connecting and exhausting member, when the telescopic cylinder is fully extended, the latch is buckled at the flat part of the L-shaped movable plate. When the telescopic cylinder contracts, it will pull the latch to move horizontally through the L-shaped movable plate, and the pressure roller moves down to the top of the diaphragm, so that the pressure roller presses the diaphragm or the water purification net during the contraction of the telescopic cylinder, so as to discharge the air between the diaphragm and the water purification net, so as to reduce the resistance of the winding rack when winding the stacked diaphragm and water purification net, thereby preventing the diaphragm and the water purification net from wrinkling during the winding process;

[0022] 2. By setting the one-way displacement unit, when the latch contacts the swing inclined rod along the horizontal section, the swing inclined rod will swing upward with the movement of the latch at this time, and the torsion spring will wind up. When the latch separates from the swing inclined rod, the swing inclined rod will be restored under the action of the torsion spring. As the L-shaped movable plate moves, one end of the latch contacts the trapezoidal blocking plate. At this time, the trapezoidal blocking plate will squeeze the latch, so as to separate the latch from the L-shaped movable plate. At this time, the first slider will drive the latch to move back under the elastic restoring force of the second return spring. At this time, the swing inclined rod guides the latch under the limitation of the second stop block and the first stop block, so that the latch moves above the support cross bar along the swing inclined rod. When the second return spring is fully extended, the latch separates from the support cross bar and falls to the top of the inclined section under the action of the third return spring at the same time, so as to realize the one-way pressing of the pressure roller on the diaphragm or the water purification net, so as to prevent the pressure roller from pushing the diaphragm or the water purification net when resetting;

[0023] 3. By setting the alternating feeding member, the controller controls the servo motor to drive the turntable to rotate 90 degrees. At this time, the turntable will drive the direct connection guide rail to move towards the positioning guide frame through the eccentric connecting pin, so as to synchronously move the first translation rack and the diaphragm placing plate towards the winding frame. At the same time, the water purification net placing plate moves towards the servo motor under the action of the reversing gear and the second translation rack, so as to move the diaphragm on the diaphragm placing plate to the stacking position. After the diaphragm is placed, the controller controls the servo motor to drive the turntable to rotate 90 degrees again. At this time, the diaphragm placing plate and the water purification net placing plate are aligned. At this time, the surface of the diaphragm can be coated by an external gluing device. Then, the controller controls the servo motor to drive the turntable to rotate 90 degrees again, so as to move the water purification net placing plate towards the winding frame. Then, the water purification net on the water purification net placing plate can be removed, which provides convenience for the taking of the water purification net and the diaphragm, and further improves the film winding efficiency.

The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0035] Please refer to Figures 1 to 8, in the embodiment of the present invention, a film winding device for reverse osmosis membrane processing includes a placement table 1. A winding rack 2 is installed at one end of the placement table 1. A controller 5 is arranged on one side of the winding rack 2. A U-shaped pressing plate 4 is inserted into the top of the placement table 1 near the winding rack 2. A first return spring 3 connected to the top of the placement table 1 is arranged at the bottom of the U-shaped pressing plate 4. Support blocks 19 are installed on both sides of the placement table 1. A telescopic cylinder 9 is installed at one end of the support block 19 away from the winding rack 2. A support seat 27 is arranged at the top of the telescopic cylinder 9. An alternating feeding member is installed on the support seat 27. The support seat 27 is connected to a membrane placement plate 13 and a purified water net placement plate 39 through the alternating feeding member. The output end of the telescopic cylinder 9 is connected to a pressing and connecting exhaust member.

[0036] In this embodiment: First, install the central tube at one end of the placement table 1 through the winding rack 2. Then connect one end of the guide cloth to the central tube, and use an external gluing device to apply glue to the other three sides of the guide cloth except the side parallel to the central tube. Through the operation of the alternating feeding member, move the membrane placement plate 13 to one side of the U-shaped pressing plate 4, pull the U-shaped pressing plate 4, and place one end of the membrane on the membrane placement plate 13 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 membrane through the first return spring 3. Then, through the operation of the alternating feeding member and the pressing and connecting exhaust member, lay the membrane on the guide cloth. During this process, make the guide cloth and the membrane fit tightly through the pressing and connecting exhaust member to reduce the air between the membrane and the guide cloth. Then, use an external gluing device to apply glue to the other three sides of the membrane except the side parallel to the central tube. Through the operation of the alternating feeding member, move the purified water net placement plate 39 to one side of the U-shaped pressing plate 4, pull the U-shaped pressing plate 4, and place one end of the purified water net on the purified water 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 purified water net through the first return spring 3. Then, through the operation of the alternating feeding member and the pressing and connecting exhaust member, lay the purified water net on the membrane. Repeat this process to stack the membrane and the purified water net, and then perform film winding through the operation of the winding rack 2.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6, the pressing and exhausting part includes a side connection guiding frame 7 installed on the side of the supporting block 19 away from the placing table 1. A guiding insertion rod 8 extending to the outside of the side connection guiding frame 7 is inserted into the inside of the side connection guiding frame 7. One end of the guiding insertion rod 8 is provided with a first slider 26 slidably connected to the inner side of the side connection guiding frame 7. One side of the first slider 26 is provided with a second return spring 6 connected to the inner wall of the side connection guiding frame 7 and located outside the guiding insertion rod 8. A translation connecting frame 25 is installed on the side of the first slider 26 close to the placing table 1. An insertion bin 24 is slidably connected to the inner side of the translation connecting frame 25. A third return spring 28 connected to the inner wall of the translation connecting frame 25 is arranged at the top of the insertion bin 24. A pin 23 extending to the outside of the insertion bin 24 is inserted into the inside of the insertion bin 24. A third return spring 28 connected to the pin 23 is also arranged inside the insertion bin 24. A displacement frame 22 located outside the translation connecting frame 25 is arranged at the top of the insertion bin 24. A pressing roller 20 is arranged at the bottom of the displacement frame 22. A trapezoidal blocking plate 18 is installed on the side of the supporting block 19 close to the placing table 1. The output end of the telescopic cylinder 9 is connected with a connecting frame 15. An L-shaped movable plate 17 matched with the trapezoidal blocking plate 18 is arranged on one side of the connecting frame 15. The supporting block 19 is divided into a horizontal section 191 and an inclined section 192. One-way displacement units located above the supporting block 19 are arranged on both sides of the placing table 1.

[0038] In this embodiment: After the U-shaped pressing plate 4 presses one end of the diaphragm, the telescopic cylinder 9 is started. Through the operation of the telescopic cylinder 9, the L-shaped movable plate 17 is separated from the trapezoidal blocking plate 18. When the inclined surface of the L-shaped movable plate 17 contacts the pin 23, the pin 23 will be extruded. When the telescopic cylinder 9 is fully extended, the pin 23 is buckled at the flat part of the L-shaped movable plate 17 under the action of the third return spring 28 inside the insertion bin 24. When the telescopic cylinder 9 contracts, the pin 23 will be pulled by the L-shaped movable plate 17 to move horizontally, so as to make the pin 23 drive the translation connecting frame 25 to move horizontally through the insertion bin 24. At this time, the displacement frame 22 moves synchronously with the insertion bin 24, and at the same time, the second return spring 6 contracts. When the pin 23 separates from the top of the inclined section 192, the third return spring 28 will push the insertion bin 24 to move downward under the action of the elastic restoring force, so as to make the pressing roller 20 move downward to the top of the diaphragm, so as to make the pressing roller 20 press 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 resistance when the winding frame 2 winds the stacked diaphragm and water purification net, thereby preventing the diaphragm and the water purification net from wrinkling during the winding process.

[0039] Please refer to Figure 2 , Figure 3 , Figure 5 , the horizontal height of the top of the horizontal section 191 is less than the horizontal height of the top of the placing table 1.

[0040] In this embodiment, by setting this structure, when the latch 23 moves onto the horizontal section 191, the pressure roller 20 makes full contact with the diaphragm or water purification net on the placement table 1.

[0041] Please refer specifically to Figure 4 、 Figure 5 , a ball is rotatably connected to the end of the latch 23 away from the insertion bin 24 through a rotating shaft.

[0042] In this embodiment, by setting this structure, the frictional force between the latch 23 and the L-shaped movable plate 17 is reduced.

[0043] Please refer specifically to Figure 1 、 Figure 5 、 Figure 6 , the one-way displacement unit includes a support crossbar 16 installed at the top of the placement table 1 and above the horizontal section 191. One end of the support crossbar 16 away from the inclined section 192 is rotatably connected to a swing inclined rod 21 through a rotating shaft. A second stop block 30 is installed at the end of the swing inclined rod 21 close to the support crossbar 16. A first stop block 29 is arranged on the support crossbar 16 above the second stop block 30. A torsion spring 31 is clamped between the swing inclined rod 21 and the support crossbar 16 through a card slot.

[0044] In this embodiment, when the latch 23 contacts the swing inclined rod 21 along the horizontal section 191, the swing inclined rod 21 will swing upward as the latch 23 moves. At this time, the torsion spring 31 is wound up. When the latch 23 separates from the swing inclined rod 21, the swing inclined rod 21 will return to its original position under the action of the torsion spring 31. As the L-shaped movable plate 17 moves, one end of the latch 23 contacts the trapezoidal blocking plate 18. At this time, the trapezoidal blocking plate 18 will squeeze the latch 23 to separate the latch 23 from the L-shaped movable plate 17. At this time, the first slider 26 will drive the latch 23 to move back under the elastic restoring force of the second return spring 6. At this time, the swing inclined rod 21 guides the latch 23 due to the limitation of the second stop block 30 and the first stop block 29, so that the latch 23 moves above the support crossbar 16 along the swing inclined rod 21. When the second return spring 6 is fully extended, the latch 23 separates from the support crossbar 16 and at the same time 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 water purification net, so as to prevent the pressure roller 20 from pushing the diaphragm or water purification net during reset.

[0045] Please refer specifically to Figure 5 、 Figure 6 , the end of the swing inclined rod 21 away from the support crossbar 16 fits against the top of the horizontal section 191, and the end of the support crossbar 16 away from the swing inclined rod 21 is flush with the end of the inclined section 192 close to the horizontal section 191.

[0046] In this embodiment: By setting this structure, when the latch 23 moves away from the inclined section 192, the swing positioning rod 21 cannot limit the latch 23. When the latch 23 is restored, the swing positioning rod 21 will guide the latch 23, so as to realize the difference in the movement and reset paths of the latch 23.

[0047] Please refer specifically to Figure 1 , Figure 7 , Figure 8 , the alternating feeding member includes a positioning and guiding frame 14 installed on the top of the support base 27. A second slider 38 is slidably connected to the inner side of the positioning and guiding frame 14. One side of the second slider 38 is provided with a water purification net placement plate 39 located above the placement table 1. The inner side of the positioning and guiding frame 14 is slidably connected with a diaphragm placement plate 13 located above the water purification net placement plate 39 through the second slider 38. One side of the second slider 38 connected to the diaphragm placement plate 13 is provided with a first translation rack 35. One side of the trapezoidal blocking plate 18 connected to the water purification net placement plate 39 is provided with a second translation rack 37. One side of the positioning and guiding frame 14 is provided with a reversing gear 36 meshing with the first translation rack 35 and the second translation rack 37. The top of the positioning and guiding frame 14 is installed with a mounting frame 12. The top of the mounting frame 12 is installed with a servo motor 10. The output end of the servo motor 10 is connected with a turntable 11. The bottom of the turntable 11 is installed with an eccentric connecting pin 32. The outside of the eccentric connecting pin 32 is sleeved with a direct connection guide rail 33. The outer wall of the direct connection guide rail 33 is installed with an extension rod 34 connected to the first translation rack 35.

[0048] In this embodiment: The controller 5 controls the servo motor 10 to drive the turntable 11 to rotate 90 degrees. At this time, the turntable 11 will drive the direct connection guide rail 33 to move towards the positioning and guiding frame 14 through the eccentric connecting pin 32, so as to synchronously move the first translation rack 35 and the diaphragm placement plate 13 towards the winding frame 2. At the same time, the water purification net placement plate 39 moves towards the servo motor 10 under the action of the reversing gear 36 and the second translation rack 37, so as to move the diaphragm on the diaphragm placement plate 13 to the stacking position. After the diaphragm is placed, the controller 5 controls the servo motor 10 to drive the turntable 11 to rotate 90 degrees again. At this time, the diaphragm placement plate 13 is aligned with the water purification net placement plate 39. At this time, the surface of the diaphragm can be coated with glue by an external gluing device. Then, the controller 5 controls the servo motor 10 to drive the turntable 11 to rotate 90 degrees again, so as to move the water purification net placement plate 39 towards the winding frame 2. Then, the water purification net on the water purification net placement plate 39 can be removed, which provides convenience for the taking of the water purification net and the diaphragm and further improves the film winding efficiency.

[0049] Please refer specifically to Figure 7 , Figure 8, the teeth on the first translation rack 35 and the second translation rack 37 face in opposite directions, and both the first translation rack 35 and the second translation rack 37 are engaged with the reversing gear 36.

[0050] In this embodiment: By setting this structure, the water purification net placement plate 39 and the diaphragm placement plate 13 are always moved in opposite directions.

[0051] Please refer specifically to Figure 7 , the diameter of the eccentric connecting pin 32 is equal to the inner wall width of the direct connecting guide 33, and the inner wall length of the direct connecting guide 33 is greater than the diameter of the turntable 11.

[0052] In this embodiment: By setting this structure, when the turntable 11 rotates, the eccentric connecting pin 32 drives the direct connecting guide 33 to perform reciprocating movement in the horizontal direction.

[0053] The following combines the above-mentioned film winding device for reverse osmosis membrane processing to provide a film winding method for reverse osmosis membrane processing, which specifically includes the following steps:

[0054] S1: First, install the central tube at one end of the placement table 1 through the winding frame 2, then connect one end of the guide cloth to the central tube, and use an external gluing device to apply glue to the other three sides of the guide cloth except the side parallel to the central tube;

[0055] S2: Control the servo motor 10 to drive the turntable 11 to rotate 90 degrees through the controller 5. At this time, the turntable 11 will drive the direct connecting guide 33 to move towards the positioning guide frame 14 through the eccentric connecting pin 32, so that the first translation rack 35 and the diaphragm placement plate 13 move synchronously towards the winding frame 2. At the same time, the water purification net placement plate 39 moves towards the servo motor 10 under the action of the reversing gear 36 and the second translation rack 37, thereby moving the diaphragm on the diaphragm placement plate 13 to the stacking position. Pull the U-shaped pressing plate 4, place one end of the diaphragm on the diaphragm placement plate 13 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 diaphragm through the first return spring 3;

[0056] S3: Activate the telescopic cylinder 9. Through the operation of the telescopic cylinder 9, the L-shaped movable plate 17 is separated from the trapezoidal blocking plate 18. When the inclined surface of the L-shaped movable plate 17 contacts the pin 23, the pin 23 will be extruded. When the telescopic cylinder 9 is fully extended, the pin 23 is buckled at the flat part of the L-shaped movable plate 17 under the action of the third return spring 28 inside the insertion bin 24. The controller 5 controls the servo motor 10 to drive the turntable 11 to rotate by another ninety degrees. At this time, the diaphragm placement plate 13 is aligned with the water purification net placement plate 39. When the telescopic cylinder 9 contracts, it will pull the pin 23 to move horizontally through the L-shaped movable plate 17, so as to make the pin 23 drive the translation connecting frame 25 to move horizontally through the insertion bin 24. At this time, the displacement frame 22 moves synchronously with the insertion bin 24, and at the same time, the second return spring 6 contracts. When the pin 23 separates from the top of the inclined section 192, the third return spring 28 will push the insertion bin 24 to move downward under the action of the elastic restoring force, so as to make the pressure roller 20 move downward 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 resistance when the winding frame 2 winds the stacked diaphragm and water purification net, thereby preventing the diaphragm and the water purification net from wrinkling during the winding process. When the pin 23 contacts the swing position inclined rod 21 along the horizontal section 191, at this time, the swing position inclined rod 21 will swing upward along with the movement of the pin 23. At this time, the torsion spring 31 winds. When the pin 23 separates from the swing position inclined rod 21, the swing position 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 pin 23 contacts the trapezoidal blocking plate 18. At this time, the trapezoidal blocking plate 18 will extrude the pin 23, so as to separate the pin 23 from the L-shaped movable plate 17. At this time, the first slider 26 will drive the pin 23 to move back under the action of the elastic restoring force of the second return spring 6. At this time, the swing position inclined rod 21 guides the pin 23 due to being limited by the second stop block 30 and the first stop block 29, so that the pin 23 moves above the support cross bar 16 along the swing position inclined rod 21. When the second return spring 6 is fully extended, the pin 23 separates from the support cross bar 16 and falls to the top of the inclined section 192 under the action of the third return spring 28 at the same time, so as to realize the one-way pressing of the pressure roller 20 on the diaphragm or the water purification net, so as to prevent the pressure roller 20 from pushing the diaphragm or the water purification net during the resetting;

[0057] S4: Through the operation of the alternating feeding member, the water purification net placement plate 39 is moved to one side of the U-shaped pressing plate 4. 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. Then, through the operation of the alternating feeding member and the pressing and exhausting member, the water purification net is laid on the diaphragm;

[0058] S5: By repeating the above steps, the diaphragm and the water purification net can be stacked, and then the film winding process can be carried out through the operation of the winding rack 2.

[0059] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
