At least two of the upper crossbar 1, the lower crossbar 2, and the middle crossbar 5 are provided with connecting pieces 6. Both sides of the bipolar plate are connected to the connecting pieces 6.

[0031] The side bar 3 is provided with a plurality of first mounting holes 3-1, and the middle vertical bar 4 is provided with a plurality of second mounting holes 4-1. The first mounting holes 3-1 and the second mounting holes 4-1 are threaded holes. A first groove 3-2 is formed in the middle of the side bar 3, and a second groove 4-2 is formed in the middle of the middle vertical bar 4. Both ends of the middle crossbar 5 are provided with first connecting blocks 5-1. The two first connecting blocks 5-1 are respectively installed in the first groove 3-2 and the second groove 4-2, and the first connecting blocks 5-1 are pressed and fixed in the first groove 3-2 and the second groove 4-2 with screws passing through the threaded holes.

[0032] The length of the first connecting block 5-1 exceeds the distance between two adjacent first mounting holes 3-1 and two adjacent second mounting holes 4-1.

[0033] The middle vertical rod 4 and the side rod 3 are provided with a plurality of mounting holes at different heights, and bolts pass through the mounting holes to be fixedly connected with the middle cross rod 5.

[0034] The upper cross rod 1 is provided with a plurality of mounting holes III 1-1, and the lower cross rod 2 is provided with a plurality of mounting holes IV 2-1. The mounting holes III 1-1 and the mounting holes IV 2-1 are threaded holes. A groove III 1-2 is formed in the middle of the upper cross rod 1, and a groove IV 2-2 is formed in the middle of the lower cross rod 2. Both ends of the middle vertical rod 4 are provided with connecting blocks II 4-3, and the two connecting blocks II 4-3 are respectively installed in the groove III 1-2 and the groove IV 2-2. Screws pass through the threaded holes to press and fix the connecting blocks II 4-3 in the groove III 1-2 and the groove IV 2-2.

[0035] The length of the connecting block II 4-3 exceeds the distance between two adjacent mounting holes III 1-1 and two adjacent mounting holes IV 2-1. The front and rear sides of the middle vertical rod 4 bulge, and the bulging part 4-4 supports on the lower cross rod 2.

[0036] An upper cover plate 7 is fixed above the upper cross rod 1, and an upper cover plate roller 7-1 is fixed above the upper cover plate 7.

[0039] The number of the middle vertical rods 4 is more than one, and middle cross rods 5 are installed between the middle vertical rods 4.

[0040] When the utility model is in use, the middle vertical rod 4 divides the material hanging device into left and right two regions. The middle cross rod 5 can be installed at different heights between the middle vertical rod 4 and the side rod 3 according to needs, so as to coat bipolar plates 10 of different specifications and sizes at the same time. The connecting blocks I 5-1 on both sides of the middle cross rod 5 are installed in the groove I 3-2 and the groove II 4-2. The length of the connecting block I 5-1 exceeds the distance between two adjacent mounting holes I 3-1 and two adjacent mounting holes II 4-1, which can ensure that the middle cross rod 5 can be fixed and pressed in the groove I 3-2 and the groove II 4-2 by screws through the mounting holes I 3-1 and the mounting holes II 4-1 at any height, so as to adapt to bipolar plates 10 of different lengths and sizes.

[0041] The left and right positions and the number of the middle vertical rods 4 can also be adjusted according to production requirements, dividing the material hanging device into left and right areas of different sizes. The second connecting blocks 4-3 on both sides of the middle vertical rod 4 are respectively installed in the third grooves 1-2 in the middle of the upper cross bar 1 and the fourth grooves 2-2 in the middle of the lower cross bar 2.
