Abstract
Description
Technical Field
[0001] The utility model belongs to the field of proton exchange membrane flattening, and specifically relates to a proton exchange membrane flattening device. Background Art
[0002] Proton exchange membrane is the core component of proton exchange membrane fuel cells and plays a key role in battery performance. It not only has a barrier effect, but also has the function of conducting protons. The full proton exchange membrane mainly uses fluorosulfonic acid proton exchange membrane; Nafion recast membrane; non-fluorinated polymer proton exchange membrane; new composite proton exchange membrane, etc.
[0003] After the proton exchange membrane is produced and processed, it needs to be rolled up by a winding device. When it is placed for a long time and needs to be taken down from the winding device, it will be found that the proton exchange membrane has warped edges. Common proton exchange membranes are not easy to flatten. If the proton exchange membrane has warped edges and is not flattened, it will cause the proton exchange membrane to wrinkle during use, affecting the use of the proton exchange membrane.
[0004] In view of this, the present utility model is proposed. Utility Model Content

[0008] Optionally, two T-shaped guide grooves are provided on the upper side of the U-shaped seat, and the slider is a T-shaped block structure. Two adjacent sliders are slidably fitted in the same T-shaped guide groove, so as to improve the sliding stability of the slider.
[0009] Optionally, a bidirectional threaded rod is rotatably engaged in the T-shaped guide groove, and the threads at both ends of the bidirectional threaded rod are in opposite directions. The two ends of the bidirectional threaded rod are respectively engaged with the threads of two sliders in the T-shaped guide groove, so that the spacing between the two sliders in the T-shaped guide groove can be adjusted by rotating the bidirectional threaded rod.

[0026] The two guide strips 5 guide the warped edges to be flattened and then enter between the two pressing rollers 2, so as to reduce the probability of the two pressing rollers 2 pressing the warped edges into wrinkles, and to improve the flattening effect on the proton exchange membrane.
[0027] The U-shaped seat 1 of this embodiment is provided with two T-shaped guide grooves 101 on the upper side, and the slider 3 is a T-shaped block structure. Two adjacent sliders 3 are slidably fitted in the same T-shaped guide groove 101, so as to improve the sliding stability of the slider 3 and the stability of the adjustment of the pressure roller 2 in the U-shaped seat 1.
[0028] A bidirectional threaded rod 102 is rotatably engaged in the T-shaped guide groove 101 of the present embodiment. The threads at both ends of the bidirectional threaded rod 102 are in opposite directions. The two ends of the bidirectional threaded rod 102 are respectively threadably engaged with the two sliders 3 in the T-shaped guide groove 101, so that the spacing between the two sliders 3 in the T-shaped guide groove 101 can be adjusted by rotating the bidirectional threaded rod 102, thereby facilitating the adjustment of the squeezing force of the two pressure rollers 2 on the proton exchange membrane.
[0029] In this embodiment, a bearing seat 103 is provided in the T-shaped guide groove 101, and a first bearing 104 is provided in the bearing seat 103. A smooth curved surface is provided on the outer side of the bottom end of the bidirectional threaded rod 102, and the bottom end of the bidirectional threaded rod 102 is fixed in the first bearing 104, so as to improve the rotation stability of the bidirectional threaded rod 102 through the first bearing 104, and to improve the stability of the spacing between the two sliders 3 in the T-shaped guide groove 101 when the bidirectional threaded rod 102 rotates.
