[0035] Example

[0036] Combination Figures 1-5As shown, this embodiment provides a continuous isostatic hot press for preparing CCM, which includes an upper pressure module, a lower pressure module, an oil scraping assembly, a press base 1, a pressure plate assembly, and a press fixing bracket 2. A roll material unloading area 11 is also provided on the same side of the upper and lower pressure modules. The bottom of the press fixing bracket 2 is mounted on the press base 1. Both the upper and lower pressure modules are mounted on the press fixing bracket 2, with the upper pressure module located above the lower pressure module. Furthermore, oil scraping assemblies are installed on both the upper and lower pressure modules. It should be noted that... Figure 3 The arrow perpendicular to the wiper assembly indicates the direction of movement of the steel strip, while the arrow parallel to the wiper assembly indicates the direction in which oil gathers along the rubber wiper strip to both sides.

[0037] Specifically, the roll feeding area 11 can hold transfer film rolls, proton exchange membrane rolls, and release film rolls. Preferably, the roll feeding area 11 can be equipped with multiple supports for holding each roll, with each corresponding roll placed on its respective support. The free ends of the transfer film rolls, proton exchange membrane rolls, and release film rolls are all located between the upper and lower pressure modules. It should be noted that the release film rolls in the roll feeding area 11 can isolate the upper steel strip 5 and lower steel strip 6 from the catalyst coating membrane, that is, it can ensure that the catalyst coating membrane (CCM) located between the upper steel strip 5 and lower steel strip 6 is not contaminated by oil during production.

[0038] The upper pressing module includes an upper pressing roller assembly and an upper steel strip 5. The upper pressing roller assembly consists of two upper pressing rollers 3, which are located at opposite ends of the upper steel strip 5. That is, the upper steel strip 5 is fitted onto the two upper pressing rollers 3 to form the upper pressing module. (Refer to...) Figure 1 As shown, there are two independent press mounting brackets 2, and an oil scraping assembly is provided between the two press mounting brackets 2. Each press mounting bracket 2 has an upper pressure roller 3 installed on its top.

[0039] The pressing module includes a pressing roller assembly and a lower steel strip 6. The pressing roller assembly consists of two pressing rollers 4, which are located at both ends of the lower steel strip 6. That is, the lower steel strip 6 is fitted onto the two pressing rollers 4 to form the pressing module. Similarly, each press mounting bracket 2 is also equipped with a pressing roller 4, and the upper pressing roller 3 is located above the pressing roller 4.

[0040] In this embodiment, the pressure plate assembly includes an upper pressure plate 7 and a lower pressure plate 8. The upper pressure plate 7 is located inside the upper steel strip 5, and the lower pressure plate 8 is located inside the lower steel strip 6. The upper steel strip 5 and the lower steel strip 6 pass through the upper pressure plate 7 and the lower pressure plate 8 for pressing. Both ends of the upper pressure plate 7 and the lower pressure plate 8 are connected to the press fixing brackets 2 provided on both sides. The upper pressure plate 7 is located above the lower pressure plate 8.

[0041] The oil scraping assembly includes an upper scraper 9 and a lower scraper 10. Preferably, there are two sets of both the upper scraper 9 and the lower scraper 10. The two sets of upper scraper 9 are respectively located at the inlet and outlet ends of the upper pressure plate 7, and the two sets of lower scraper 10 are located on the lower steel belt 6. Specifically, the lower scraper 10 located on the lower steel belt 6 can be used to remove the small amount of oil generated during the operation of the press and the oil dripping from below.

[0042] Furthermore, the oil scraping assembly also includes mounting brackets 15, wherein there are two sets of mounting brackets 15, which are located at both ends of the upper oil scraper 9 and the lower oil scraper 10. Specifically, the upper oil scraper 9 and the lower oil scraper 10 are connected to the mounting brackets 15 at both ends via connecting brackets 16, which can be L-shaped. Both the upper scraper plate 9 and the lower scraper plate 10 are provided with pin holes, and are connected by guide pins and screws 17 installed in the pin holes. Specifically, the guide pins pass through the corresponding pin holes on the upper scraper plate 9 and the lower scraper plate 10, and the guide pins have threaded holes for installation. The screws 17 are installed in the threaded holes, and the tightening and loosening of the screws 17 drives the tightening and loosening of the guide pins, thereby adjusting the oil scraping gap between the upper scraper plate 9 and the lower scraper plate 10. The end of the upper scraper plate 9 is provided with a first connecting hole, and the corresponding position of the connecting bracket 16 is provided with a first waist hole 18. The diameter of the first waist hole 18 is larger than the diameter of the first connecting hole. The first fixing member passes through the first connecting hole and the first waist hole 18 to achieve the connection between the upper scraper plate 9 and the lower scraper plate 10. The scraper blade 9 and the connecting bracket 16 are connected. Similarly, the end of the lower scraper blade 10 is provided with a second connecting hole, and the corresponding position of the connecting bracket 16 is provided with a second waist hole 19. The diameter of the second waist hole 19 is also larger than that of the second connecting hole. The upper scraper blade 9 and the connecting bracket 16 are connected by a second fixing member passing through the second connecting hole and the second waist hole 19. It should be noted that both the first fixing member and the second fixing member can be bolts. Therefore, when adjusting the gap between the upper scraper blade 9 and the lower scraper blade 10, the characteristics of the first waist hole 18 and the second waist hole 19 can be used to fix and adjust the gap. Preferably, the longer sections of the first waist hole 18 and the second waist hole 19 are set in the vertical direction. The operation process is as follows: Since the upper scraper 9 is in contact with the inner side of the upper steel belt 5, the upper steel belt 5 may cause a certain degree of wear to the structure of the upper scraper 9 during operation. Similarly, since the lower scraper 10 is in contact with the inner side of the lower steel belt 6, the lower steel belt 6 may cause a certain degree of wear to the structure of the lower scraper 10 during operation. Therefore, it is only necessary to periodically adjust the gap according to the wear condition.

[0043] In this embodiment, the upper scraper 9 and the lower scraper 10 have the same structure. Taking the structure of the upper scraper 9 as an example, the specific structure of the lower scraper 10 will not be repeated. Specifically, the upper scraper 9 includes an oil-absorbing body 20, a rear sealing plate 21, a rubber scraper strip 22, and a rubber strip pressure plate 23.

[0044] Specifically, the oil-absorbing body 20 has an oil-absorbing cavity 25 inside, and a vacuum oil-absorbing hole is provided on the outer surface of the oil-absorbing body 20. The vacuum oil-absorbing hole is connected to the inside of the oil-absorbing cavity 25, and vacuum oil-absorbing pipes 24 are installed at both ends of the oil-absorbing body 20. The vacuum oil-absorbing pipes 24 are connected to the inside of the oil-absorbing cavity 25. The rear sealing plate 21 is installed on one side of the oil-absorbing body 20. Preferably, the oil-absorbing body 20, the vacuum oil-absorbing pipes 24 and the rear sealing plate 21 can be combined into one piece by welding to ensure that there is no air leakage or oil leakage.

[0045] Furthermore, a rubber scraper 22 is fixed on one side of the oil suction body 20. The rubber scraper 22 and the rear sealing plate 21 are located on different sides of the oil suction body 20, and a rubber strip pressure plate 23 is fixedly installed on the outside of the rubber scraper 22. When the vacuum suction pipe 24 is connected to the vacuum port of the external vacuum pump, it can ensure that the negative pressure on both sides of the upper scraper 9 is maximized, and the oil on the inner side of both sides of the upper steel strip 5 is sucked away through the vacuum suction hole as much as possible.

[0046] The working principle of this oil scraper assembly is as follows:

[0047] The upper scraper 9 and lower scraper 10 adjust the vertical gap between the two sets of scraper blades by adjusting the screw 17 and the guide pin, ensuring that the rubber scraper strips 22 on the upper scraper 9 and lower scraper 10 are tightly fitted to the inner sides of the upper steel belt 5 and lower steel belt 6. The guide pin between the upper scraper 9 and lower scraper 10 ensures that the rubber scraper strips 22 of the upper scraper 9 and lower scraper 10 can contact the upper steel belt 5 and lower steel belt 6 perpendicularly. When the upper steel belt 5 and lower steel belt 6 move, the sealing lubricating oil will accumulate on both sides of the rubber scraper strips 22 under the action of the upper steel belt 5 and lower steel belt 6. At the same time, the vacuum oil suction holes of the upper scraper 9 and lower scraper 10 will suck the oil away and discharge it to the outside of the lower steel belt 6.

[0048] In some other embodiments, a set of laser non-destructive degreasing components 12 can be provided on one side of the upper pressure roller assembly and the lower pressure roller assembly, respectively. The laser non-destructive degreasing component 12 includes a laser and an infrared thermal imager. Specifically, a flat-top beam field lens (with uniform energy distribution to avoid local overheating) and a green laser (532nm) can be used to further and effectively remove oil stains from the contact surface with the product. In addition, the infrared thermal imager monitors and adjusts the laser emission power in real time so that the surface temperature of the upper steel strip 5 and the lower steel strip 6 is less than 300°C.

[0049] Furthermore, the laser focus is adjusted to a position 0.01-0.02mm above the surface of the corresponding upper steel strip 5 or lower steel strip 6. The specific value needs to be determined based on the oil thickness test. The laser dynamic focusing system (0.001mm accuracy) ensures that the energy density reaches its peak at the oil layer, while the energy attenuates to within a safe threshold on the substrate surface. An external infrared thermal imager can monitor and adjust the power of the laser generator in real time. The oil on the outer surface of the upper steel strip 5 and lower steel strip 6 is rapidly vaporized; when the laser beam reaches the steel strip surface, the spot diffuses, and the energy density is below the metal damage threshold. Through calculation, energy density = laser power / (scanning speed × spot diameter), where the unit of energy density is J / cm², the unit of laser power is W, the unit of scanning speed is m / s, and the unit of spot diameter is mm, thus allowing for precise control of the laser's energy density.

[0050] In some other embodiments, an upper smoke collection device 13 is provided on one side of the upper pressure roller assembly, and a lower smoke collection device 14 is provided on one side of the lower pressure roller assembly. It should be noted that the upper smoke collection device 13 and the lower smoke collection device 14 can be installed near the upper pressure roller assembly and the lower pressure roller assembly respectively (without direct contact) through a support structure such as a fixing frame (not shown in the figure). When the laser non-destructive degreasing assembly 12 degreases the outer surfaces of the upper steel strip 5 and the lower steel strip 6, the pollutants such as flue gas generated can be collected by the upper smoke collection device 13 and the lower smoke collection device 14 respectively, reducing the degree of environmental pollution.

[0051] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
