Description

Technical Field

[0001] This utility model relates to the field of coating technology for ion exchange membrane processing, and more specifically, it relates to a coating device for ion exchange membrane processing. Background Technology

[0002] Ion exchange membranes are used in electrodialysis, reverse electrodialysis, electrolysis, diffusion dialysis, and many other processes. Typically, ion transport occurs through the membrane under the influence of driving forces such as an ion concentration gradient or, optionally, a potential gradient; based on their primary charge, ion exchange membranes are generally classified as cation exchange membranes or anion exchange membranes; cation exchange membranes contain negatively charged groups that allow cations to pass through but repel anions, while anion exchange membranes contain positively charged groups that allow anions to pass through but repel cations.

[0003] Currently, coating devices for ion exchange membrane processing on the market often have the following technical problems during use:

[0004] Existing coating devices for ion exchange membrane processing have difficulty in stretching and straightening the ion exchange membrane before coating. This leads to wrinkles on the ion exchange membrane during the coating process, resulting in uneven coating of the ion-conducting polymer. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coating device for ion exchange membrane processing that can stretch and straighten the ion exchange membrane to be coated between two adjusting rollers before coating, so as to avoid wrinkles on the surface of the ion exchange membrane to be coated during the later coating process, and to avoid uneven coating of ion-conducting polymer materials due to wrinkles on the surface of the coated ion exchange membrane.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A coating apparatus for processing ion exchange membranes includes a processing component, on which a coating component is inserted and fixed.

[0008] The processing component includes a processing part and an adjustment control that slides on the processing part.

[0009] The processed part includes a base plate, on the top of which are fixed symmetrical side plates. A positioning roller is fixed between the two side plates. Two symmetrical vertical grooves are opened through one side of one side plate. A guide groove is fixed on one side of the other side plate. I-shaped sliders are slidably fitted inside the two vertical grooves. A baffle is fixed on one side of each of the two I-shaped sliders. An adjusting roller is fixed on one side of the baffle. A lever is fixed on the opposite side of each of the two I-shaped sliders.

[0010] The control unit includes a T-shaped slider that slides inside the guide channel. A U-shaped slide plate is fixed to one side of the T-shaped slider, and a slide plate is fixed to one side of the U-shaped slide plate. Two symmetrical inclined grooves are opened through one side of the U-shaped slide plate, and the two inclined grooves slide with two levers respectively.

[0011] The present invention is further configured such that: a dual-axis motor is fixed on one side of the side plate between the two vertical grooves, and a threaded lead screw is fixed on one output shaft of the dual-axis motor.

[0012] The slide plate has a threaded hole through one side that is rotatably connected to the threaded screw.

[0013] The present invention is further configured such that two symmetrical plug-in posts are fixed to the top of both side plates.

[0014] The coating assembly includes a U-shaped fixing plate, on which ear plates are fixed on both outer sides, and the ear plates are inserted into the plug.

[0015] The present invention is further configured such that: another output shaft of the dual-axis motor is fixed with a rotating shaft, and a first bevel gear is fixed at one end of the rotating shaft.

[0016] Two symmetrical inclined plates are fixed on the top of the base plate away from the side plates. A rotating shaft is rotatably fitted between the two inclined plates away from the circumferential side of the positioning roller. A second bevel gear that meshes with the first bevel gear is fixed on one end of the rotating shaft away from the inclined plate.

[0017] The present invention is further configured such that: two symmetrical sliding rods are slidably fitted through the top of the U-shaped fixed plate, and a U-shaped lifting plate is fixed inside the U-shaped fixed plate at the bottom of the two sliding rods; a coating roller is rotatably fitted on the inner wall of the U-shaped lifting plate.

[0018] The present invention is further configured such that: two symmetrical swing arms are fixed on the circumferential side of the rotating shaft between the two inclined plates, and a toggle groove is provided through one side of each of the two swing arms.

[0019] The tops of the two sliding rods are fixed with irregularly shaped frames outside the U-shaped fixing plate. Two symmetrical buffer springs are fixed between the top of the inner side of the irregularly shaped frame and the top of the outer side of the U-shaped fixing plate. The two buffer springs are respectively sleeved and engaged with the two sliding rods.

[0020] The present invention is further configured such that: each of the two outer sides of the irregular frame is fixed with a toggle rod, and the two toggle rods are respectively slidably engaged with the two toggle grooves.

[0021] The irregularly shaped frame has a storage box fixed inside. A flexible hose is connected to the top of the storage box, and an oil nozzle is connected to the bottom of the storage box.

[0022] The advantages of this utility model are: 1. This utility model uses the sliding cooperation between the two inclined grooves and the two levers to drive the two I-shaped sliders to make linear movements that move away from or towards each other inside the two vertical grooves, thereby ultimately driving the two adjusting rollers to make linear movements that move away from or towards each other synchronously. This stretches and straightens the ion exchange membrane to be coated between the two adjusting rollers before coating, avoiding wrinkles on the surface of the ion exchange membrane to be coated during the later coating process, and preventing uneven coating of the ion-conducting polymer due to wrinkles on the surface of the coated ion exchange membrane.

[0023] 2. This utility model utilizes the sliding engagement between the actuating groove and the actuating rod penetrating one side of the swing arm to drive the U-shaped lifting plate to slide downwards inside the U-shaped fixed plate. This allows the coating roller to come into contact with the surface of the ion exchange membrane to be coated, which is wrapped around the periphery of the positioning roller. Subsequently, through the winding and conveying of the ion exchange membrane to be coated, the coating roller, which is rotated and engaged with the inner wall of the U-shaped lifting plate, performs synchronous rolling coating. This prevents excessive accumulation of the ion-conducting polymer in a certain area of ​​the ion exchange membrane after spraying, ensuring that the ion-conducting polymer is evenly coated on the surface of the ion exchange membrane, thereby improving the coating effect of the ion exchange membrane.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0036] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0037] Example 1, please refer to Figure 1-9This utility model provides the following technical solution: Specifically, it refers to a coating device for ion exchange membrane processing, comprising a processing component 1, on which a coating component 2 is inserted and fixed; the processing component 1 includes a processing part 3 and an adjustment control 4 slidably fitted on the processing part 3; the processing part 3 includes a base plate 301, with symmetrical two side plates 302 fixed to the top of the base plate 301, a positioning roller 304 fixed between the two side plates 302, two symmetrical vertical grooves 303 penetrating one side of one side plate 302, and a guide channel 305 fixed to one side of one side plate 302, the two vertical grooves 303... The internal components are fitted with I-shaped sliders 306, and baffles 307 are fixed on one side of each I-shaped slider 306. An adjusting roller 308 is fixed on one side of each baffle 307. A lever 309 is fixed on the opposite side of each I-shaped slider 306. The adjusting control 4 includes a T-shaped slider 401 that is fitted inside the guide channel 305. A U-shaped slide plate 402 is fixed on one side of the T-shaped slider 401. A slide plate 403 is fixed on one side of the U-shaped slide plate 402. Two symmetrical inclined grooves 404 are opened through one side of the U-shaped slide plate 403. The two inclined grooves 404 are fitted with the two levers 309 respectively.

[0038] Furthermore, a dual-axis motor 310 is fixed on one side of the plate 302 between the two vertical grooves 303, and a threaded screw 311 is fixed on one output shaft of the dual-axis motor 310; a threaded hole 405 is provided on one side of the slide plate 403 for threaded rotational connection with the threaded screw 311.

[0039] The specific application of this embodiment is as follows: Before coating the ion exchange membrane with the polymer of the ion-conducting material, the dual-axis motor 310 is started, driving the threaded screw 311 fixed to one output shaft of the dual-axis motor 310 to rotate. This rotation is achieved through the threaded connection between the threaded hole 405 and the threaded screw 311, causing the slide plate 403 to rotate threadedly on the circumferential side of the threaded screw 311. When the slide plate 403 rotates threadedly on the circumferential side of the threaded screw 311, it limits the circumferential rotation of the entire adjustment control 4 through the sliding engagement between the T-shaped slider 401 and the guide channel 305. This causes the entire adjustment control 4 to move horizontally within the guide channel 305, thus moving the entire adjustment control 4 horizontally. When the guide channel 305 moves horizontally, it provides sliding engagement between the two inclined grooves 404 inside the adjustment control 4 and the two levers 309, respectively. This causes the two I-shaped sliders 306 to move linearly away from or towards each other within the two vertical grooves 303, which in turn causes the two adjusting rollers 308 to move linearly away from or towards each other synchronously. This stretches and straightens the ion exchange membrane to be coated between the two adjusting rollers 308 before coating, preventing wrinkles from appearing on the surface of the ion exchange membrane during the later coating process. This also prevents uneven coating of the ion-conducting polymer due to wrinkles on the surface of the coated ion exchange membrane.

[0040] Example 2, please refer to Figure 1-9 This second embodiment is an improvement on the first embodiment as follows: Specifically, two symmetrical insertion posts 312 are fixed to the top of each of the two side plates 302; the coating assembly 2 includes a U-shaped fixing plate 201, and ear plates 202 are fixed to the two opposite outer sides of the U-shaped fixing plate 201. The ear plates 202 are inserted into the insertion posts 312 (after the ear plates 202 are inserted into the insertion posts 312, they are fixed by rotating the external nut with the thread between the external nut and the insertion post 312, thus fixing the coating assembly 2 in place for further processing). (For later coating operations); the other output shaft of the dual-axis motor 310 is fixed with a rotating shaft 313, and one end of the rotating shaft 313 is fixed with a first bevel gear 314; two symmetrical inclined plates 315 are fixed on the top of the base plate 301 away from the side plates 302, and a rotating shaft 316 is rotatably fitted between the two inclined plates 315 away from the circumference of the positioning roller 304, and a second bevel gear 317 that meshes with the first bevel gear 314 is fixed on one end of the rotating shaft 316 away from one of the inclined plates 315; U-shaped fixing plate 201 Two symmetrical sliding rods 203 are slidably connected through the top of the inner part of the U-shaped fixed plate 201. A U-shaped lifting plate 204 is fixed inside the bottom of the two sliding rods 203. A coating roller 205 is rotatably connected to the inner wall of the U-shaped lifting plate 204. Two symmetrical swing arms 318 are fixed on the circumferential side of the rotating shaft 316 between two inclined plates 315. A sliding groove 319 is provided on one side of each swing arm 318. A shaped frame 206 is fixed outside the U-shaped fixed plate 201 at the top of the two sliding rods 203. Two symmetrical buffer springs 207 are fixed between the inner top of the 206 and the outer top of the U-shaped fixing plate 201. The two buffer springs 207 are respectively sleeved with two sliding rods 203. A lever 208 is fixed on each of the two opposite outer sides of the irregular frame 206. The two levers 208 are respectively slidably engaged with two lever grooves 319. A storage box 209 is fixed inside the irregular frame 206. A flow hose 210 is connected to the top of the storage box 209, and an oil nozzle 211 is connected to the bottom of the storage box 209.

[0041] A specific application of this embodiment is as follows: During the use of this device, the winding equipment is first set up on one side of the drying equipment. Then, the drying equipment is positioned between this device and the winding equipment. The ion exchange membrane to be coated is then sequentially unwound, coated, dried, and wound up. (The drying equipment is prior art; for details, please refer to Chinese Utility Model Patent Publication No. CN221558876U. The drying equipment here has the same structure as the drying mechanism in Chinese Utility Model Patent Publication No. CN221558876U, but it is not shown in the figure and will not be elaborated upon here. The winding equipment described in this device is also prior art; for details, please refer to Chinese Utility Model Patent Publication No. CN221558876U. The drying equipment here has the same structure as the drying mechanism in Chinese Utility Model Patent Publication No. CN221558876U.) The winding roller in Chinese Utility Model Patent CN221558876U has the same structure, which is not shown in the figure and will not be elaborated on here. The unwinding process of this device has been explained in paragraph 39 of the specification of Chinese Utility Model Patent No. CN221558876U (which is also prior art and will not be elaborated on here). During the coating operation, the starting end of the ion exchange membrane to be coated is first passed over an adjusting roller 308, then between the coating roller 205 and the positioning roller 304, then under another adjusting roller 308, and subsequently inside the drying equipment. Finally, the starting end of the ion exchange membrane to be coated is wound onto the winding device, thus completing the preparation work before coating the ion exchange membrane (a detailed diagram after the preparation work is completed can be found in [reference]). Figure 9 This is to facilitate coating operations during the later transportation process;

[0042] After the above equipment has completed its operation, the dual-axis motor 310 is started, driving the rotating shaft 313 fixed to its other output shaft to rotate. This drives the first bevel gear 314 to rotate, causing the second bevel gear 317, which meshes with it, to rotate synchronously. This causes the entire rotating shaft 316 to rotate between the two inclined plates 315, causing the two swing arms 318 fixed to the circumference of the rotating shaft 316 to rotate downwards synchronously. When the two swing arms 318 fixed to the circumference of the rotating shaft 316 rotate downwards at a certain angle, the actuating groove 319 through one side of the swing arm 318 and the actuating rod 20... The sliding engagement between the 8 rods causes the U-shaped lifting plate 204 to slide downward inside the U-shaped fixed plate 201. When the U-shaped lifting plate 204 slides downward inside the U-shaped fixed plate 201, it slides downward through the two sliding rods 203 fixed to the top of the U-shaped fixed plate 201, and the U-shaped fixed plate 201. Combined with the elastic force of the two buffer springs 207 fixed between the irregular frame 206 and the U-shaped fixed plate 201, the coating roller 205, which is rotated and engaged with the inner wall of the U-shaped lifting plate 204, moves downward until the coating roller 205 is engaged with the positioning roller 304. After the surfaces of the ion exchange membranes to be coated are aligned, the dual-axis motor 310 is turned off. Later, when coating the ion-conducting polymer onto the ion exchange membranes, the oil nozzle 211 connected to the bottom of the storage tank 209 is simultaneously activated to spray the ion-conducting polymer stored inside the storage tank 209. (During the addition of the ion-conducting polymer inside the storage tank 209, the flexible hose 210 connected to the top of the storage tank 209 can be connected to the outlet of the external ion-conducting polymer transfer device to facilitate subsequent polymerization of the ion-conducting polymer.) The addition of the polymer (the external ion-conducting material polymer transport device is not shown in the existing technical drawings and will not be elaborated on here) allows the ion-conducting material polymer to be sprayed onto the surface of the ion exchange membrane to be coated. Subsequently, through the winding and transport of the ion exchange membrane to be coated, the coating roller 205, which is coordinated with the inner wall of the U-shaped lifting plate 204, rotates synchronously to coat the membrane. This prevents the sprayed ion-conducting material polymer from accumulating excessively in a certain area of ​​the ion exchange membrane, so that the ion-conducting material polymer can be evenly coated on the surface of the ion exchange membrane, thereby improving the coating effect of the ion exchange membrane.

[0043] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
