Description

Technical Field

[0001] This invention relates to the field of reverse osmosis membrane production, specifically a winding device for reverse osmosis membrane production. Background Technology

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane with specific properties, mimicking a biological semi-permeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis is that, under pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus separating them from water. The membrane pores of a reverse osmosis membrane are extremely small, enabling it to effectively remove dissolved salts, colloids, microorganisms, organic matter, and other substances from water.

[0003] After production, reverse osmosis membranes need to be evenly wound onto take-up rollers for easy transport. However, existing winding devices used in reverse osmosis membrane production require periodic disassembly and replacement of the take-up rollers, which is extremely inconvenient and significantly reduces the winding efficiency of the reverse osmosis membranes.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-7As shown, the present invention discloses a winding device for reverse osmosis membrane production, comprising a support plate 1 and a winding roller 13. L-shaped fixing frames 2 are symmetrically fixedly connected to both ends of the top of the support plate 1. A fixing plate 3 is fixedly connected to the side wall of the L-shaped fixing frame 2 away from the support plate 1. A servo motor 5 is fixedly connected to the wall of the fixing plate 3 via a fixing frame 4. A rotating shaft 7 is fixedly connected to the output end of the servo motor 5 via a coupling 6. The other end of the rotating shaft 7 passes through the fixing plate 3 and is rotatably connected to the fixing plate 3. A reverse drive sleeve 8 and a forward drive sleeve 9 are sleeved on the shaft wall of the end of the rotating shaft 7 passing through the fixing plate 3. The reverse drive sleeve 8 and the forward drive sleeve 9 are respectively rotatably inserted into the side wall of the L-shaped fixing frame 2 away from the support plate 1. On both sides of the support plate 1, a transmission gear 10 is fixedly sleeved on the outer wall of the reverse transmission sleeve 8, and a grab wheel 11 is fixedly sleeved on the outer wall of the forward transmission sleeve 9. Several grab grooves 12 are evenly spaced on the outer side wall of the grab wheel 11.

Two rotating grooves 15 are formed through the top of the support plate 1 corresponding to the positions of the two grab wheels 11. Corresponding tooth grooves 14 are formed on the outer walls of both ends of the take-up roller 13, and the take-up roller 13 is connected to the transmission gear 10 through the tooth grooves 14. Several first reverse grooves 81 are evenly spaced on the inner wall of the reverse transmission sleeve 8.

A plurality of second reversing grooves 87 are equidistantly opened on the shaft wall inside the reversing transmission sleeve 8 of the rotating shaft 7. A reversing driving wedge block 86 is slidably inserted into the interior of the second reversing groove 87. The reversing driving wedge block 86 is matched with the reversing driven wedge block 82. A second reversing spring 88 is fixedly connected to the inner wall of the second reversing groove 87, and the other end of the second reversing spring 88 is fixedly connected to the reversing driving wedge block 86. A plurality of second reversing grooves 88 are equidistantly opened on the inner wall of the clockwise transmission sleeve 9. A plurality of first rotating grooves 91 are provided, and a rotating driven wedge block 92 is slidably inserted into the interior of the first rotating groove 91. A first rotating spring 93 is fixedly connected to the inner wall of the first rotating groove 91, and the other end of the first rotating spring 93 is fixedly connected to the rotating driven wedge block 92. A plurality of second rotating grooves 97 are equidistantly opened on the shaft wall inside the rotating transmission sleeve 9 of the rotating shaft 7. A rotating active wedge block 96 is slidably inserted into the interior of the second rotating groove 97. The rotating active wedge block 96 is matched with the rotating driven wedge block 92. A second rotating spring 98 is fixedly connected to the inner wall of the second rotating groove 97, and the other end of the second rotating spring 98 is fixedly connected to the rotating active wedge block 96.

[0028] The reversing driven wedge block 82 is slidably inserted into the side wall of one end of the first reversing groove 81 and fixedly connected to the first reversing limiting slider 84. The inner wall of the first reversing groove 81 is provided with a matching first reversing limiting groove 85 corresponding to the first reversing limiting slider 84, and the first reversing limiting slider 84 is slidably connected inside the first reversing limiting groove 85. When the first reversing limiting slider 84 slides inside the first reversing limiting groove 85, it can make the reversing driven wedge block 82 slide more stably inside the first reversing groove 81. The reversing active wedge block 86 is slidably inserted into the side wall of one end of the second reversing groove 87 and fixedly connected to the second reversing limiting slider 89. The inner wall of the second reversing groove 87 is provided with a matching second reversing limiting groove 810 corresponding to the second reversing limiting slider 89, and the second reversing limiting slider 89 is slidably connected inside the second reversing limiting groove 810. When the second reversing limiting slider 89 slides inside the second reversing limiting groove 810, it can make the reversing active wedge block 86 slide more stably inside the second reversing groove 87. The rotary driven wedge block 92 is slidably inserted into the side wall of one end of the first rotary groove 91 and fixedly connected to a first rotary limiting slider 94. The inner wall of the first rotary groove 91 is provided with a first rotary limiting groove 95 corresponding to the first rotary limiting slider 94, and the first rotary limiting slider 94 is slidably connected inside the first rotary limiting groove 95. When the first rotary limiting slider 94 slides inside the first rotary limiting groove 95, it can make the rotary driven wedge block 92 slide more stably inside the first rotary groove 91.

[0029] The rotating active wedge block 96 is slidably inserted into the side wall of one end of the second rotating groove 97 and fixedly connected to a second rotating limiting slider 99. A matching second rotating limiting groove 910 is formed on the inner wall of the second rotating groove 97 corresponding to the second rotating limiting slider 99, and the second rotating limiting slider 99 is slidably connected inside the second rotating limiting groove 910. When the second rotating limiting slider 99 slides inside the second rotating limiting groove 910, it makes the rotating active wedge block 96 slide more stably inside the second rotating groove 97. Both servo motors 5 are electrically connected to an external power supply through a PLC controller. The TB6600 PLC controller can control the two servo motors 5 to drive synchronously, and the controller can effectively control the speed and direction of the servo motors 5, effectively ensuring that the device can drive normally.

[0030] The top of the support plate 1 is provided with a matching roller groove 16 corresponding to the take-up roller 13. The roller groove 16 is connected to the rotating groove 15, so that after the take-up roller 13 is placed inside the roller groove 16, the grab wheel 11 can grab the take-up roller 13 through the grab groove 12.

[0031] The fixed frame 4 is fixedly sleeved on the outer wall of the servo motor 5, and the fixed frame 4 is fixedly connected to the wall of the fixed plate 3 by screws, which facilitates the disassembly and assembly of the servo motor 5.

[0032] In use, a take-up roller 13 is placed in the roller groove 16 at the top of the support plate 1. Under the action of gravity, the take-up roller 13 moves downward along the inclined side of the roller groove 16. The output ends of two servo motors 5 are controlled by the PLC controller to rotate clockwise synchronously. The output ends of the servo motors 5 drive the rotating shaft 7 to rotate clockwise. When the rotating shaft 7 rotates clockwise, it can drive the clockwise driven wedge block 92 through the clockwise active wedge block 96, thereby causing the clockwise driven wedge block 92 to drive the clockwise transmission sleeve 9 to rotate clockwise. When the clockwise transmission sleeve 9 rotates clockwise, it can drive the grab wheel 11 to rotate clockwise. When the grab wheel 11 rotates clockwise inside the rotating groove 15, it can grab the take-up roller 13 inside the roller groove 16 through the grab groove 12. Located inside the gripping groove 12, as the gripping wheel 11 continues to rotate, the gripping wheel 11 will drive the take-up roller 13 to move clockwise upwards. When the take-up roller 13 moves to mesh with the transmission gear 10, the controller controls the output end of the servo motor 5 to drive the rotating shaft 7 to rotate counterclockwise. When the rotating shaft 7 rotates counterclockwise, it can drive the reverse driven wedge block 82 to move through the reverse active wedge block 86. The reverse driven wedge block 82 will drive the reverse transmission sleeve 8 and the transmission gear 10 to rotate counterclockwise. When the transmission gear 10 rotates counterclockwise, it can drive the take-up roller 13 meshed with it to wind up the reverse osmosis membrane. When the take-up roller 13 finishes winding, the controller controls the servo motor 5 to rotate clockwise. The take-up roller 13 that has wound up the reverse osmosis membrane will then disengage from the gripping wheel 11 along the gripping groove 12, so that the device can automatically complete the disassembly and replacement of the take-up roller 13, which greatly improves the winding efficiency of the reverse osmosis membrane.
