Technical Field

[0001] This application relates to the technical field of diaphragm edge clamping, and particularly to an edge clamping device for an alkaline electrolytic water hydrogen production diaphragm. Background Art

[0002] The alkaline electrolytic water hydrogen production diaphragm is a technology for electrolyzing water to produce hydrogen. During the process of the alkaline electrolytic water hydrogen production diaphragm, water is electrolyzed into hydrogen and oxygen, and the diaphragm plays a role in separating the generated hydrogen and oxygen. The traditional alkaline electrolytic water hydrogen production diaphragm technology uses alkaline electrolytic water hydrogen production diaphragm quality solutions such as sodium hydroxide (NaOH) or potassium hydroxide (KOH) as the electrolyte, and at the same time uses a solid polymer membrane as the diaphragm. This technology has the advantages of high hydrogen production efficiency and low cost, so it is widely used in the industrial and energy fields.

[0003] During the production process of the alkaline electrolytic water hydrogen production diaphragm, coating processing needs to be carried out. The quality of the coating substrate is of great significance to the excellent rate of the finished product quality of the alkaline electrolytic water hydrogen production diaphragm. During the coating process, factors such as the self-correction accuracy of the equipment or the levelness of the adjusting roller are extremely likely to cause the substrate entering and leaving the coating oven to form wrinkles, which in turn leads to coating belt breakage and shutdown, having a greater impact on both the product quality and cost. Therefore, further improvements can be made. Utility Model Content

[0031] The following further elaborates on the present application in conjunction with the attached Figure 1-2 drawings.

[0032] An embodiment of the present application discloses an edge clamping device for an alkaline electrolyzed water hydrogen production diaphragm.

[0033] Referring to Figure 1 , an edge clamping device for an alkaline electrolyzed water hydrogen production diaphragm includes a rectangular connecting cross plate 1 that can be connected to a coater. At both ends of the connecting cross plate 1, L-shaped connecting side plates 2 are symmetrically arranged. The bottom of the connecting side plate 2 is fixedly connected to the end of the connecting cross plate 1 in the length direction, and the connecting side plate 2 and the connecting cross are perpendicularly arranged to each other. An edge clamping mechanism 3 is arranged on the inner side wall of the connecting side plate 2;

[0034] During actual use, the edge clamping mechanism 3 is set, and the two clamping mechanisms on the two connecting side plates clamp the edge of the substrate, flattening the substrate and reducing the generation of wrinkles, thereby reducing the occurrence of the coater stopping due to tape breakage.

[0035] Referring to Figure 1 , 2 , specifically, in this embodiment, the edge clamping mechanism 3 includes a first edge pressing wheel 31 and a second edge pressing wheel 32. The first edge pressing wheel 31 is installed above the second edge pressing wheel 32. A gap exists between the first edge pressing wheel 31 and the second edge pressing wheel 32 to form a conveying channel for the edge of the substrate to pass through, and the distance between the first edge pressing wheel 31 and the second edge pressing wheel 32 is adjustable;

[0036] At the top of the inner wall of the connecting side plate 2, a driving mounting plate 21 is provided. The driving mounting plate 21 is perpendicularly arranged with the connecting side plate 2. At the top of the driving mounting plate 21, a driving cylinder 4 is provided. The movable end at the bottom of the driving cylinder 4 penetrates through the driving mounting plate 21 and is equipped with a first mounting seat 22. A first pressing wheel 31 is installed in the first mounting seat 22. The first pressing wheel 31 is provided with a first connecting shaft 33 along its length direction. Both ends of the first connecting shaft 33 are fixedly connected to both sides of the bottom of the first mounting seat 22. The first pressing wheel 31 is installed in the first mounting seat 22 through the first connecting shaft 33;

[0037] At the bottom of the first pressing wheel 31 on the inner wall of the connecting side plate 2, a second mounting seat 23 is provided. A second pressing wheel 32 is installed in the second mounting seat 23. The second pressing wheel 32 is provided with a second connecting shaft 34 along its length direction. Both ends of the second connecting shaft 34 are rotatably connected to both sides of the top of the second mounting seat 23. The second pressing wheel 32 is rotatably connected in the second mounting seat 23 through the second connecting shaft 34. To enable the second connecting shaft 34 to drive the second pressing wheel 32 to rotate, a motor mounting seat 24 is provided on the outer wall of the connecting side plate 2. The motor mounting seat 24 is perpendicularly arranged with the connecting side plate 2. Between the bottom of the motor mounting seat 24 and the connecting side plate 2, a support rib plate 25 is provided to reinforce the motor mounting seat 24 and increase the structural stability of the motor mounting seat 24. A driving motor 5 is installed on the top of the motor mounting seat 24. A coupling 6 is installed on the movable end of the driving motor 5 on the side close to the connecting side plate 2.
