Description

Technical Field

[0001] This invention relates to the field of reverse osmosis membrane preparation technology, specifically to a multifunctional automatic reverse osmosis membrane winding device. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN222833700U, which discloses a multifunctional automatic reverse osmosis membrane winding device, specifically relating to the field of reverse osmosis membrane preparation technology. The device includes a base, a worktable fixedly mounted on the top of the base, a guide cloth slidably mounted on the top of the base, and multiple layers of membrane sheets fixedly mounted on the top of the guide cloth. A second support column is fixedly mounted on one side of the top of the base, and a winding roller is rotatably mounted on the top of the second support column. The guide cloth is fixedly mounted on the outside of the winding roller. By setting up a pressing roller, a pressing rod, and a first spring, after manual membrane laying, the rotating shaft and the winding roller rotate synchronously, causing the guide cloth to carry the membrane sheets into the bottom of the pressing roller. At this point, the membrane... The device pushes the extrusion roller, which in turn drives the extrusion rod to squeeze the first spring. After being squeezed, the first spring pushes the extrusion rod in the opposite direction, which in turn drives the extrusion roller to squeeze the membrane, making the guide cloth and the membrane adhere more tightly and squeezing out excess adhesive. This effectively improves the winding quality of the reverse osmosis membrane. However, the membrane wraps around and squeezes the extrusion roller. The extrusion roller moves along the extrusion rod under the action of the spring, which can cause the membrane to be wrapped too tightly and not flat enough. After the membrane is wrapped, it is difficult to remove it from the extrusion roller. Moreover, the extrusion roller is prone to deviation during the winding process, which affects the flatness of the membrane and cannot be adapted to membranes of different widths. In addition, the device does not have an automatic dispensing device, so the dispensing work cannot be completed more conveniently. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-11As shown, the present invention is a multifunctional reverse osmosis membrane automatic winding device, including a workbench 1, on which a winding mechanism 2 and a dispensing mechanism 6 are respectively arranged; the winding mechanism 2 includes a first motor 21 and a support rod 22. The first motor 21 is fixedly connected to the bottom of the workbench 1, and the output end of the first motor 21 is fixedly connected to a main pulley 23. One end of the support rod 22 is fixedly connected to a driven pulley 24. A belt 25 is movably connected between the main pulley 23 and the driven pulley 24. The other end of the support rod 22 is fixedly connected to a central rod 26. One end of the central rod 26 is fixedly connected to a limit plate 27. A threaded tube 28 is sleeved on the surface of the central rod 26. One end of the threaded tube 28 is fixedly connected to a handle 29. Support components 3 are provided between the support rod 22 and the threaded tube 28 and the workbench 1.

[0034] The support assembly 3 includes a support plate 31, which is fixedly connected to the workbench 1. An arc-shaped cover plate 32 is hinged to the support plate 31, and a first screw 33 is threadedly connected to the arc-shaped cover plate 32. One end of the first screw 33 is threadedly connected to the support plate 31.

[0035] The support rod 22 and the threaded tube 28 are respectively located in the grooves of the support plate 31 on the corresponding side, and the support rod 22 and the threaded tube 28 are rotatably connected to the support plate 31 and the arc-shaped cover plate 32 on the corresponding side.

[0036] A tensioning assembly 4 is provided between the support rod 22 and the threaded tube 28. The tensioning assembly 4 includes a roller plate 41, and four roller plates 41 are provided. Each of the four roller plates 41 is fixedly connected to a plate beam 42. A first connecting rod 43 and a second connecting rod 44 are rotatably connected to the plate beam 42. The first connecting rod 43 and the second connecting rod 44 are rotatably connected to each other. There are two first connecting rods 43 and two second connecting rods 44 symmetrically arranged. One end of each of the two first connecting rods 43 is rotatably connected to a fixing ring 45. The fixing ring 45 is fixedly connected to the support rod 22.

The threaded ring 47 is threadedly connected to the threaded tube 28.

[0037] When the threaded tube 28 is rotated, the threaded ring 47 on the threaded tube 28 will move along the threaded tube 28 along with the adjusting ring 46. The support rod 22 and the pulley 24 have a certain weight, which makes the support rod 22 and the pulley 24 have a self-locking effect. In addition, the threaded tube 28 is rotatably connected to the center rod 26, and the friction is very small, so that when the threaded tube 28 rotates, it cannot drive the support rod 22 and the pulley 24 to rotate through the tensioning assembly 4, thus ensuring the effectiveness of the opening and closing movement of the tensioning assembly 4.

[0038] A limiting component 5 is provided on the roller plate 41. The limiting component 5 includes a slide groove 51. A first limiting rod 52 is fixedly connected in the slide groove 51.

The trapezoidal platform 57 is slidably connected in the vertical groove of the cross groove 55. A wedge 58 is slidably connected in the horizontal groove of the cross groove 55. Two wedges 58 are symmetrically arranged.

[0039] The threaded tube 28 is rotatably connected to the center rod 26, the support rod 22, and the limiting plate 27.

[0040] The tension and retraction of the roll plate 41 are controlled by adjusting the distance between the fixed ring 45 and the adjusting ring 46 by rotating the threaded tube 28, which facilitates the demolding work after the film is rolled. With the help of the adjustable second limit rod 53, the permeate membrane is less likely to deviate during the film rolling process, which can adapt to permeate membranes of different widths without affecting the flatness of the film roll.

[0041] The dispensing mechanism 6 includes an electric slide rail 61 and a support column 62. There are two electric slide rails 61 and two support columns 62 symmetrically arranged. A slider 63 is slidably connected to each of the two electric slide rails 61. The two support columns 62 are respectively fixedly connected to the slider 63 on the corresponding side. A lifting groove 64 is opened on the support column 62. A second motor 65 is fixedly connected to the support column 62. The output end of the second motor 65 passes through the support column 62 and is fixedly connected to a first lead screw 66. The first lead screw 66 is rotatably connected in the lifting groove 64.

[0042] The electric slide rail 61 is existing technology, and its input terminal is connected to an external power source.

[0043] An adjustment assembly 7 is provided between the two support columns 62. The adjustment assembly 7 includes a horizontal connecting plate 71 and a second lead screw 72. Lifting blocks 73 are fixedly connected to both ends of the horizontal connecting plate 71. The two lifting blocks 73 are threadedly connected to the first lead screw 66 on the corresponding side. The two ends of the second lead screw 72 are rotatably connected to the lifting blocks 73 on the corresponding side. A third motor 74 is fixedly connected to the horizontal connecting plate 71. The output end of the third motor 74 passes through the horizontal connecting plate 71 and is fixedly connected to a worm gear 75. A worm wheel 76 is fixedly connected to the second lead screw 72. The worm gear 75 and the worm wheel 76 mesh with each other.

[0044] An adjustment groove 77 is provided on the cross plate 71. An adjustment seat 78 is slidably connected in the adjustment groove 77. The adjustment seat 78 is threadedly connected to the second lead screw 72. A glue tank 79 is fixedly connected to the adjustment seat 78.

[0045] The glue container 79 contains glue, which is applied to the permeation membrane through the dropper below.

[0046] The lifting block 73 is slidably connected to the lifting groove 64, and the horizontal connecting plate 71 is slidably connected to the support column 62.

[0047] The horizontal position of the glue tank 79 is adjusted by the electric slide rail 61, the vertical position of the glue tank 79 is adjusted by the second lead screw 72, and the height of the glue tank 79 is adjusted by the first lead screw 66, thereby achieving the purpose of dispensing glue at any position on the permeation membrane, which is convenient, quick, and improves productivity.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0049] The working principle of this invention is as follows: During dispensing, the second motor 65 drives the first lead screw 66 to rotate, causing the lifting block 73 to move the horizontal connecting plate 71, the second lead screw 72, the adjusting seat 78, and the glue tank 79 on the first lead screw 66 to adjust the height. The third motor 74 drives the worm gear 75 to rotate, thereby driving the worm wheel 76 and the second lead screw 72 to rotate, which in turn drives the adjusting seat 78 and the glue tank 79 to move on the second lead screw 72 to adjust the lateral position of the glue tank 79. The slider 63 drives the support column 62 to slide on the electric slide rail 61, thereby driving the support column 62 and the horizontal connecting plate 71 to move along the electric slide rail 61 to adjust the vertical position of the glue tank 79. During film winding, the permeable membrane is pulled onto the winding roller plate 41, according to the permeable membrane... The position of the second limiting rod 58 is adjusted by rotating the second screw 56 to push the trapezoidal platform 57 down and squeeze the wedge block 58 to move outward in the horizontal groove of the cross groove 55 and squeeze the slide groove 51, thereby fixing the second limiting rod 58. The first motor 21 drives the support rod 22 to rotate through the main pulley 23, belt 25 and driven pulley 24, thereby driving the tensioning assembly 4 to rotate and roll up the permeate membrane. When removing the rolled-up permeate membrane, unscrew the first screw 33 and open the arc-shaped cover plate 32. Rotate the threaded tube 28 through the handle 29 to adjust the position of the threaded ring 47 and the adjusting ring 46, thereby driving the second connecting rod 44 to rotate with the first connecting rod 43, and then driving the winding roller plate 41 to retract, so that the permeate membrane can be removed.
