[0002] Hydrogen energy has been widely recognized around the world as an efficient and clean secondary energy source. 2 It is an important process for achieving large-scale production. Compared with PEM water electrolysis, alkaline water electrolysis is more mature. In the alkaline electrolyzer, the cathode produces H 2 , the anode produces O 2 If the diaphragm is not used, H 2 , O 2 Strict separation will cause H 2 , O 2 Mixing not only fails to achieve the purpose of production, but also brings safety hazards.

[0003] The chemical and physical properties of diaphragms have become a hot topic of research. In the early days, asbestos was used as a diaphragm material, but its swelling properties in alkaline electrolytes and its harm to the human body led to its gradual elimination. Currently, the industry widely uses new composite diaphragms based on polyphenylene sulfide (PPS) fabric.

[0040] Combined with Figure 1, Attachment Figure 4 and attached Figure 5 As shown, the pinch roller 2 includes a motor 21 and two roller bodies 23, the two roller bodies 23 are rotatably arranged between the two side plates 11, a gear 24 is provided at one end of the roller body 23, the two gears 24 are meshed, a gear 22 meshed with one of the gears 24 is provided at the output end of the motor 21, a guide roller 12 is rotatably provided at the rear side of the pinch roller 2 between the two side plates 11, and a collecting trough 13 is provided under the guide roller 12 on the main frame 1.

[0041] Working principle of the pinch roller 2: Motor 1 21 drives gear 1 22 to rotate, and gear 1 22 is meshed with gear 2 24 to rotate gear 24, and the two rollers 23 are meshed with each other to rotate in opposite directions, thereby clamping the substrate and moving it. The substrate moves in the main frame 1 through the pinch rollers 2 at the substrate input and output ends of the main frame 1. After passing through the guide roller 12, the substrate passes vertically upward through the feeding mechanism 3, the scraping mechanism 5, and the smoothing mechanism 6 in turn, and then is guided by the movable frame 7 and enters the cooling pool 17 to solidify the coating material.

[0042] Combined with Figure 4 , Attachment Figure 6 and attached Figure 7 As shown, the feeding mechanism 3 includes two groups of symmetrically arranged material plates 31 and baffles 32 and a feeding pipe 33, a slide bar 2 321 is provided on the main frame 1, the baffle 32 is slidably arranged on the slide bar 2 321, the bottom of the baffle 32 is slidably matched with the material plate 31, and the feeding pipe 33 feeds the coating material to between the baffles 32 on both sides of the substrate, the feeding pipe 33 includes a main pipe 331 and a branch pipe 332, and a plurality of discharge ports 333 are provided on the branch pipe 332, a slide bar 311 is provided on the main frame 1, the material plate 31 is slidably matched with the slide bar 311, springs 312 connected to the inner side of the side plate 11 are provided at both ends of the material plate 31, a transmission plate 313 is provided at one end of the material plate 31, and the end of the transmission plate 313 passes through the through hole on the side plate 11.

[0043] Working principle of feeding mechanism 3: coating material enters main pipe 331 through external input device and flows to two branch pipes 332 respectively. Outlet 333 on the outside of two baffles 32 is blocked with plugs to prevent discharge. Material flows from outlet 333 between baffles 32 to two material plates 31. Two symmetrical baffles 32 confine coating material to a certain area. Two material plates 31 are tilted. Base material passes through the gap between two material plates 31 and baffles 32. Coating material hangs on base material when the base material passes through. Two baffles 32 can slide on slide bar 2 321 to adapt to base materials of different widths. They are fixed to slide bar 2 321 by bolts. The gap between adjacent baffles 32 is smaller than the gap between two material plates 31. The gap between adjacent baffles 32 allows base material to pass through and prevents coating material from flowing in, thereby limiting coating width.

[0044] Combined with Figure 4 and attached Figure 8 As shown, a driving mechanism 4 for driving the material plate 31 to reciprocate is provided on the main frame 1, and the driving mechanism 4 includes a motor 2 41 and a cam 46. The cam 46 is rotatably arranged on the outer side of the side plate 11, and the cam 46 cooperates with the transmission plate 313. The driving mechanism 4 also includes a gear 42, a bevel gear 1 43, and a bevel gear 2 44. The two ends of the gear 42 are coaxially connected with the two bevel gears 1 43. The output end of the motor 2 41 is provided with a gear 3 411 meshing with the gear 42. The bevel gear 2 44 is rotatably arranged on the side plate 11, and the bevel gear 1 43 meshes with the bevel gear 2 44. One end of the cam 46 is coaxially connected to the bevel gear 3 45, and the bevel gear 3 45 meshes with the bevel gear 2 44.

[0045] Working principle of driving mechanism 4: motor 2 41 drives gear 3 411 to rotate, and gear 3 411 meshes with gear 4 42 to drive bevel gear 1 43 coaxially connected to gear 4 42 to rotate, and bevel gear 1 43 meshes with bevel gear 2 44 to drive, and bevel gear 2 44 meshes with bevel gear 3 45 to drive cam 46 coaxially connected to bevel gear 3 45 to rotate. When cam 46 rotates, spring 1 312 makes transmission plate 313 always fit with cam 46, so that the rotation of cam 46 drives material plate 31 to reciprocate through transmission plate 313, realizing lateral vibration effect, so that coating material flows to the upper end of material plate 31 through discharge port 333, and then reciprocates through material plate 31, so that when coating material flows to the gap at the lower end of material plate 31, it is spread evenly, and bubbles in coating material are discharged, so that coating material is evenly hung on substrate.

[0046] Combined with Figure 4 , Attachment Fig. 9 , Attachment Fig.10 , Attachment Fig.11 , Attachment Fig.12 and attached Fig.13As shown, the scraper mechanism 5 includes two symmetrically arranged angle rollers 51, a plurality of mounting platforms 511 are evenly arranged on the angle roller 51, and a scraper 512 is installed on the mounting platform 511. The working lines of the plurality of scrapers 512 are at different distances from the axis of the angle roller 51, and the distance increases in the rotation order. Functional platforms 52 and fixed platforms 53 are respectively rotatably arranged at both ends of the angle roller 51. The functional platforms 52 and the fixed platforms 53 are slidably arranged in the adjustment groove 14 on the side plate 11. A stop plate 522 is slidably arranged in the groove at the top of the functional platform 52. Springs 2 523 are arranged on both sides of the bottom of the stop plate 522. An inserting platform 524 is arranged at the bottom of the stop plate 522. The inserting platform 524 is connected to the stop plate 522 through a spring 3 525. A groove wheel 513 is arranged at one end of the angle roller 51, and the inserting platform 524 is plugged into the slots 515 evenly arranged on the groove wheel 513. In cooperation, a limiting cylinder 55 is provided on the side plate 11, and a pressure plate 551 is provided at the output end of the limiting cylinder 55. The pressure plate 551 contacts and cooperates with the abutment plate 522. The angle roller 51 is provided with a ratchet 514 on the outer side of the groove wheel 513, and a rocker rod 526 is rotatably provided on the outer side of the ratchet 514. A limiting platform 521 cooperating with the rocker rod 526 is provided on the function platform 52, and a pawl 528 is rotatably provided on the rocker rod 526. The pawl 528 cooperates with the ratchet 514, and the rear end of the pawl 528 is connected to the rocker rod 526 through a spring four 529. A transmission wheel 527 is rotatably provided at the outer end of the rocker rod 526. A displacement cylinder 54 is provided on the side plate 11, and a push plate 541 is provided at the output end of the displacement cylinder 54. The push plate 541 cooperates with the transmission wheel 527. A guide column 15 slidably cooperates with the push plate 541 and the pressure plate 551 is provided on the side plate 11.

[0047] Working principle of scraper mechanism 5: When the substrate passes through the gap between the adjacent scrapers 512 of two angle rollers 51, the scraper 512 scrapes off a part of the coating material on the substrate to control the coating thickness. A plurality of scrapers 512 of different widths are installed on the angle roller 51 to facilitate the adjustment of coating thickness by tool change. When tool change is required, the limit cylinder 55 drives the pressure plate 551 to move upward, the push plate 522 moves upward under the push of spring 2 523, the inserting platform 524 is pulled upward by spring 3 525 and disengages from the slot 515, and then the displacement cylinder 54 pushes the push plate 541 to move upward, and the push plate 541 continues to move upward after contacting the transmission wheel 527, so that the swing rod 526 rotates, and the spring 4 529 makes the end of the ratchet 528 stick to the ratchet wheel 514. When the ratchet 528 moves with the swing rod 5 When the cam 524 is rotated, the ratchet 514 is driven to rotate, so that the scraper 512 on the angle roller 51 changes its position, so that the next scraper 512 moves to the working position, so as to achieve the automatic tool changing effect. After the ratchet 514 rotates, the limit cylinder 55 drives the pressure plate 551 to reset, so that the pressure plate 551 drives the abutment plate 522 to move downward, and the inserting platform 524 that moves downward with the abutment plate 522 moves into the groove of the groove wheel 513, and the spring 3 525 is compressed, and the bottom of the inserting platform 524 slides in the groove of the groove wheel 513. When the next scraper 512 moves to the working position, the inserting platform 524 is inserted into the slot 515 to prevent the angle roller 51 from continuing to rotate. When the tool needs to be jumped for replacement, the limit cylinder 55 controls the downward movement time of the pressure plate 551 according to how many scrapers 512 are skipped.

[0048] During rough adjustment, before moving the functional table 52 and the fixed table 53, move the widest scraper 512 to the working position, and then make the functional table 52 and the fixed table 53 slide in the adjustment groove 14 to control the minimum spacing and the centering position of the two scrapers 512. After the adjustment is completed, tighten the functional table 52 and the fixed table 53 by bolts. During fine adjustment, the coating thickness is fine-tuned by replacing the scraper 512, and the rotation of the angle roller 51 can be adjusted manually.

[0049] Combined with Figure 4 , Attachment Fig.14 , Attachment Fig.15 and attached Fig.16As shown, the smoothing mechanism 6 includes smoothing rollers 61 that are symmetrically arranged, and the distance between the two smoothing rollers 61 is smaller than the distance between the two scrapers 512. The smoothing mechanism 6 also includes an adjustment frame 65 and a threaded rod 67. The adjustment frame 65 is slidably arranged in the adjustment slot 19 on the side plate 11. Adjustment platforms 62 are rotatably arranged at both ends of the smoothing roller 61. The adjustment platform 62 is slidably arranged in the adjustment frame 65. The adjustment platform 62 is provided with threaded holes that cooperate with the threaded rod 67. The threads at both ends of the threaded rod 67 are in opposite directions. A handle 66 is provided at one end of the threaded rod 67. A scraping platform 63 is provided between the adjustment platforms 62 at both ends of the smoothing roller 61. The scraping platform 63 cooperates with the smoothing roller 61. A discharge pipe 64 is provided, which transports excess coating material back to the material plate 31. The smoothing mechanism 6 also includes a driven mechanism 68 that drives the smoothing roller 61 to rotate. The driven mechanism 68 includes a rotating rod 681, on which a driven wheel 682 is slidably provided. The driven wheel 682 is fixed to the rotating rod 681 by bolts according to the width of the substrate. Pulley 2 683 is provided at both ends of the rotating rod 681, and pulley 1 611 is provided at both ends of the smoothing roller 61. An adjustment block 685 is provided in the side plate 11, and a tensioning wheel 684 is rotatably provided on the adjustment block 685. Pulley 1 611, pulley 2 683 and tensioning wheel 684 are coordinated through belt transmission.

[0050] Working principle of the smoothing mechanism 6: Since the number of scrapers 512 installed on the angle roller 51 is limited, the coating thickness controlled by the scraper 512 is limited and cannot be precisely controlled. The smoothing mechanism 6 is required to further control the coating thickness and make the coating surface smoother. The adjustment frame 65 slides in the adjustment slot 19 to adjust the centering position of the two smoothing rollers 61. After the adjustment is completed, the adjustment frame 65 is tightened with bolts. When fine-tuning, the handle 66 is turned to rotate the threaded rod 67. Since the threads at both ends of the threaded rod 67 are in opposite directions, the two adjustment platforms 62 on the same side move toward each other, thereby precisely controlling the two The spacing between the smoothing rollers 61 is adjusted by adjusting the position of the adjustment block 685 on the side plate 11, so that the tensioning wheel 684 adjusts the belt tension. When the edge of the substrate passes through the gap between the two driven wheels 682, the driven wheel 682 is driven to rotate, and the rotating rod 681 drives the pulley 2 683 to rotate, and the belt transmission cooperates to drive the pulley 1 611 to rotate, driving the smoothing roller 61 to rotate. The coating material adhering to the smoothing roller 61 will be scraped off by the side of the scraping table 63 when passing through the scraping table 63. The scraping table 63 collects the excess coating material and re-transports it to the material plate 31 through the discharge pipe 64.

[0051] Combined with Figure 2 and attached Fig.17As shown, the movable frame 7 is slidably matched with the slide bar 3 16 on the main frame body 1, and a plurality of guide wheels 1 71 and guide wheels 2 72 are rotatably provided on the movable frame 7, and the guide wheels 1 71 and guide wheels 2 72 act on the edge of the substrate and guide it, the guide wheel 1 71 is arranged on the top of the side plate 11, and the guide wheel 2 72 is arranged in the cooling pool 17, and the plurality of guide wheels 2 72 and the plurality of guide rollers 2 18 are respectively staggered and arranged.

[0052] Working principle of the movable frame 7 and the guide roller 2 18: the movable frame 7 can slide on the slide bar 3 16, so as to adjust the distance between the two movable frames 7 according to the width of the substrate. There is no coating on the edge of the substrate, and the edge of the substrate is guided by the guide wheel 1 71 and the guide wheel 2 72 to allow the substrate to enter the cooling pool 17. The guide wheel 1 71 and the guide wheel 2 72 do not contact the coating area to prevent affecting the coating thickness before solidification. Multiple guide wheels 2 72 and multiple guide rollers 2 18 are staggered and arranged to increase the retention time of the substrate in the cooling pool 17. The coating is initially solidified at the position of the guide wheel 2 72 and further solidified when passing through the guide roller 2 18. The guide roller 2 18 will not affect the coating thickness. The cooling pool 17 needs to control the internal coolant temperature and be equipped with a circulation system (not shown) to improve the solidification efficiency.

[0053] When the present invention is implemented, the substrate is driven by the pinch rollers 2 at the front and rear ends of the main frame 1 to move in the main frame 1. After passing through the guide roller 12, the substrate moves vertically upward and passes through the feeding mechanism 3, the scraping mechanism 5, and the smoothing mechanism 6 in turn. The driving mechanism 4 causes the material plate 31 of the feeding mechanism 3 to feed in a lateral vibration manner. The scraping mechanism 5 performs preliminary control of the coating thickness and changes the tool through the automatic tool changing structure. The smoothing mechanism 6 accurately controls the coating thickness. Subsequently, the substrate enters the cooling pool 17 after being guided by the guide wheel 1 71 on the movable frame 7. The coating is cooled and solidified by the coolant. The guide wheel 2 72 and the guide roller 2 18 increase the residence time of the substrate in the cooling pool 17. After passing through the pinch roller 2, the substrate enters the winding device for winding processing.
