Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis membrane edge pressing, in particular to an automatic edge pressing device for reverse osmosis membrane preparation. Background Art

[0002] Reverse osmosis technology is a high-efficiency membrane separation technology widely used in water treatment. Its basic principle is based on the osmosis phenomenon. By applying a pressure higher than the natural osmotic pressure, water molecules are forced to pass through the semipermeable membrane in reverse, thereby achieving the separation of solutes and solvents. In the reverse osmosis process, by applying pressure to the high-concentration solution, water molecules are forced to pass through the membrane in reverse, thereby obtaining pure water on the low-pressure side. The core of this process is the reverse osmosis membrane, which can effectively block dissolved salts, particulate matter and organic pollutants.

[0003] Reverse osmosis membranes are widely used in various fields. In the process of preparing reverse osmosis membranes, in order to ensure the quality of the reverse osmosis membranes, they need to be subjected to edge pressing treatment. The existing edge pressing treatment method usually uses two pressing rollers to clamp and press the film up and down. During the edge pressing process, it is very easy to cause uneven force on the reverse osmosis membrane, resulting in wrinkles or tears in the reverse osmosis membrane, which reduces the quality of the reverse osmosis membrane and causes the reverse osmosis membrane to fail to play its maximum role in various fields.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the automatic edge pressing device for reverse osmosis membrane preparation currently available on the market, and even if it can be solved, it needs to be solved through the cooperation of external tools, thus failing to achieve the desired effect.

At the same time, when the pulley 2111 moves out of the guide groove of the guide rail 2106, the reaction force of the first spring 2120 can return the pressure roller 2104 to its original position.

[0038] The leveling unit 22 includes a first rotating rod 2202, one end of which is fixedly connected to the surface of the rotating disk 2103, a first transmission wheel 2201 is fixedly installed on the other end of the first rotating rod 2202, a fixing plate 2210 is fixedly installed on one side of the fixing rod 2107, a second rotating rod 2206 is rotatably connected to the inner wall of the fixing plate 2210, one end of the second rotating rod 2206 is fixedly installed with the second transmission wheel 2204, a belt 2203 is arranged on the top of the fixing plate 2210, the belt 2203 is sleeved on the surfaces of the first transmission wheel 2201 and the second transmission wheel 2204, a mounting frame 2207 is fixedly installed on the other end of the second rotating rod 2206, a mounting rod 2208 is slidably installed on the surface of the mounting frame 2207, the number of the mounting rods 2208 is several, and a leveling brush 2209 is fixedly installed on the bottom of the mounting rod 2208;

[0041] By setting up the coordinated use of the edge pressing unit 21 and the flattening unit 22, the purpose of ensuring the edge pressing effect can be achieved, and the edge pressing method in which the pressing roller 2104 and the reverse osmosis membrane move in relative directions can ensure that the reverse osmosis membrane is uniformly stressed during the edge pressing process. This uniform stress can reduce the deformation and wrinkles of the reverse osmosis membrane, thereby improving the flatness and tightness of the edge pressing, while avoiding the reverse osmosis membrane from tearing, thereby ensuring the processing quality of the reverse osmosis membrane and enabling the reverse osmosis membrane to play its greatest role in various fields.

[0042] The specific implementation of this embodiment is as follows: when the user needs to perform edge pressing treatment on the reverse osmosis membrane, the user first uses the control terminal 12 to start the device body 11, and the start of the device body 11 transports the reverse osmosis membrane. At this time, the user uses the external control switch and power supply to start the dual-axis motor 2102, and the start of the dual-axis motor 2102 drives the two turntables 2103 to rotate, and the rotation of the turntable 2103 drives the first rotating rod 2202 to rotate, and the rotation of the first rotating rod 2202 drives the first transmission wheel 2201 to rotate, and the rotation of the first transmission wheel 2201 drives the second transmission wheel 2204 to rotate through the belt 2203, and the rotation of the second transmission wheel 2204 drives the second rotating rod 2206 to rotate, and the second rotating rod 2 206 rotates through the bearing 2205 and the fixed plate 2210, the rotation of the second rotating rod 2206 drives the mounting frame 2207 to rotate, the rotation of the mounting frame 2207 drives the mounting rod 2208 to rotate, and the rotation of the mounting rod 2208 drives the leveling brush 2209 to rotate. Since the leveling brush 2209 is made of a flexible material, the leveling brush 2209 will not cause damage to the reverse osmosis membrane when leveling the reverse osmosis membrane. During the rotation of the leveling brush 2209, it will level the folded reverse osmosis membrane to facilitate subsequent edge pressing processing. After the reverse osmosis membrane is leveled, the reverse osmosis membrane will be continuously transported. The rotation of the turntable 2103 will also drive the fixed cylinder 2108 to rotate. The rotation of the fixed cylinder 2108 The movable rod 2112 is driven to rotate, and the rotation of the movable rod 2112 drives the positioning plate 2113 to rotate, and the rotation of the positioning plate 2113 drives the rotating shaft 2114 to rotate, and the rotation of the rotating shaft 2114 drives the supporting shell 2116 to rotate, and the rotation of the supporting shell 2116 drives the housing 2117 to rotate, and the rotation of the housing 2117 drives the fixing block 2121 to rotate, and the rotation of the fixing block 2121 drives the fixing shaft 2105 to rotate, and the rotation of the fixing shaft 2105 drives the pressing roller 2104 to rotate, and the fixing block 2121 rotates while driving the mounting plate 2110 to rotate, and the rotation of the mounting plate 2110 drives the pulley 2111 to rotate, so that the pulley 2111 enters the guide groove of the guide rail 2106 , moves along the guide groove of the guide rail 2106. When one of the pressure rollers 2104 rotates to a vertical state with the reverse osmosis membrane, the pulley 2111 will be guided by the guide groove of the guide rail 2106, so that the upper and lower pulleys 2111 move in relative directions. The pulley 2111 drives the mounting plate 2110 to move during the movement. The movement of the mounting plate 2110 drives the fixed block 2121 to move. The movement of the fixed block 2121 drives the first sliding sleeve 2119 to press the first spring 2120 on the surface of the first sliding rod 2118, so that the upper and lower pressure rollers 2104 can contact the upper and lower surfaces of the reverse osmosis membrane. After the contact, the pulley 2111 will move through the rotation of the turntable 2103 and the linear guidance of the guide rail 2106.The linear movement of the pulley 2111 will drive the installation plate 2110 to move linearly, the linear movement of the installation plate 2110 will drive the fixed block 2121 to move, the linear movement of the fixed block 2121 will drive the support shell 2116 to move, the linear movement of the support shell 2116 will rotate with the positioning plate 2113, and at the same time, the torsion spring 2115 will be twisted, and the movable rod 2112 will also be pulled. When the movable rod 2112 is pulled, it will pull the tension spring 2109, so that the upper and lower pressure rollers 2104 can move in a linear direction, so that the movement between the pressure roller 2104 and the reverse osmosis membrane can move in relative directions, until one of the pulleys 2111 is about to leave the guide groove of the guide rail 2106, and the other pulley 2111 will enter the guide rail 2106. The straight line guide position ensures that the reverse osmosis membrane is always pressed. When the pulley 2111 is separated from the guide groove of the guide rail 2106, the pressing roller 2104 will return to its original position through the reaction force of the torsion spring 2115 and the tension spring 2109. Repeating the above steps can complete the pressing of the reverse osmosis membrane, achieving the purpose of ensuring the pressing effect. The pressing roller 2104 and the reverse osmosis membrane move in relative directions to ensure that the reverse osmosis membrane is uniformly stressed during the pressing process. This uniform stress can reduce the deformation and wrinkles of the reverse osmosis membrane, thereby improving the flatness and tightness of the pressing, and avoiding the tearing of the reverse osmosis membrane, ensuring the processing quality of the reverse osmosis membrane, and enabling the reverse osmosis membrane to play its greatest role in various fields.

[0043] Example 2: Please refer to Figure 1 - Figure 8 The present invention provides a technical solution: an automatic edge pressing device for preparing a reverse osmosis membrane. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0044] As a further limitation of the edge pressing mechanism 2 of the present invention, an auxiliary mechanism 3 is provided inside the flattening unit 22, and the auxiliary mechanism 3 is used in conjunction with the flattening unit 22, and the auxiliary mechanism 3 is used to prevent the flattening unit 22 from causing damage to the reverse osmosis membrane;

[0045] The auxiliary mechanism 3 includes a connecting rod 302, one end of which is fixedly mounted on the surface of the fixing frame 2101, and the other end of the connecting rod 302 is fixedly mounted with a guide opening ring 301, and the surface of the mounting frame 2207 is provided with a slide groove 303, and the number of the slide grooves 303 is several. A second slide rod 304 is fixedly mounted on the inner wall of the slide groove 303, and a second sliding sleeve 306 is slidably mounted on the surface of the second slide rod 304, and a guide block 307 is fixedly mounted on one side of the second sliding sleeve 306, and one side of the guide block 307 is fixedly connected to one side of the mounting rod 2208. By setting the auxiliary mechanism 3, the purpose of increasing the leveling effect can be achieved. In the process of pressing the reverse osmosis membrane, it can be ensured that the reverse osmosis membrane will not be folded for the second time, and then it can be ensured that the reverse osmosis membrane will not be folded before pressing the reverse osmosis membrane, and the effect of pressing the reverse osmosis membrane is further increased;

[0046] A second spring 305 is fixedly installed at the bottom of the second sliding sleeve 306, one end of the second spring 305 is fixedly installed on the inner wall of the sliding groove 303, and the second spring 305 is sleeved on the surface of the second sliding rod 304. By setting the second spring 305, the leveling brush 2209 can be returned to its original position through the reaction force of the second spring 305, so that the leveling brush 2209 will not contact the reverse osmosis membrane when it is not completely moved to the upper and lower surfaces of the reverse osmosis membrane, thereby avoiding the phenomenon of causing the boundary of the reverse osmosis membrane to be moved;

[0047] One end of the guide opening ring 301 is provided with an inclined surface, and the guide block 307 is used in conjunction with the inclined surface of the guide opening ring 301 .

[0048] The specific implementation of this embodiment is as follows: when the reverse osmosis membrane is leveled, the rotation of the mounting frame 2207 drives the guide block 307 to rotate. When the guide block 307 rotates to a position in contact with the inclined surface of the guide opening ring 301, the guide block 307 drives the second sliding sleeve 306 to squeeze the second spring 305 on the surface of the second sliding rod 304 during the rotation process, thereby driving the mounting rod 2208 to move. The movement of the mounting rod 2208 drives the leveling brush 2209 to move to a position in contact with the upper and lower surfaces of the reverse osmosis membrane, thereby leveling the folds of the reverse osmosis membrane. When the guide block 307 moves to the opening of the guide opening ring 301, the leveling brush 2 209 will be reset by the reaction force of the second spring 305, so that the leveling brush 2209 moves to a position where it cannot contact the reverse osmosis membrane. When the leveling brush 2209 rotates to a position almost parallel to the reverse osmosis membrane, the leveling brush 2209 will not move the edge of the reverse osmosis membrane until the leveling brush 2209 is completely rotated to the upper and lower surfaces of the reverse osmosis membrane. The leveling brush 2209 will move to a position in contact with the reverse osmosis membrane, thereby achieving the purpose of increasing the leveling effect. In the process of pressing the reverse osmosis membrane, it can be ensured that the reverse osmosis membrane will not fold for the second time, and further ensure that the reverse osmosis membrane will not fold before pressing the reverse osmosis membrane, thereby further increasing the effect of pressing the reverse osmosis membrane.
