Figure 2As shown), the other end of the one-way feed pipe 28 is connected to an external container storing composite electrolyte slurry, and the one-way feed pipe 28 only allows the external composite electrolyte slurry to enter the slide 26, the slide 26 is connected to the first feed chamber 15 through the first one-way discharge pipe 29, and the slide 26 is connected to the second feed chamber 20 through the second one-way discharge pipe 30.

[0026] Further, the motor 22 is started to drive the take-up roller 11 to rotate, and the motor 22 will synchronously drive the driving wheel 23 to rotate, and then drive the first driven wheel 24 and the second driven wheel 25 to rotate, and drive the first unloading roller 3 and the second unloading roller 5 to rotate. The rotation of the take-up roller 11 will reel up the composite electrolyte membrane, and the rotation of the first unloading roller 3 and the second unloading roller 5 will discharge the silicone oil paper and the support membrane, and then the whole device starts to run, and the rotation of the second unloading roller 5 will drive the first cam 33 to rotate, and then the first cam 33 cooperates with the first spring 32 to drive the push rod 31 to slide back and forth, and drive the sliding plug 27 to slide back and forth in sealing. At the same time, the external composite electrolyte slurry will be drawn into the slide 26 through the one-way feed pipe 28, and then the composite electrolyte slurry will enter the first feed cavity 15 and the second feed cavity 20 through the first one-way discharge pipe 29 and the second one-way discharge pipe 30 respectively, and the composite electrolyte slurry will be sprayed onto the A surface of the silicone oil paper through multiple first spray holes 16, and then enter the preheating box 6 for drying, and then the B surface of the silicone oil paper will be sprayed, and it will be rolled up after drying again. Spraying, pressing, drying, and rolling are automatically completed in an integrated manner, with good production continuity and higher efficiency, and can greatly reduce the equipment footprint and reduce production costs.

[0027] The preheating box 6 is provided with a drying mechanism, which includes a first chute 34 (such as Fig. 9 As shown in the figure, the first slide groove 34 is arranged through the side wall of the preheating box 6, the inner wall of the first slide groove 34 is slidably connected with a slide bar 35, the side wall of the slide bar 35 is fixedly connected with a drying plate 36, an air inlet cavity 37 is opened in the drying plate 36, and a plurality of jet holes 38 are opened on the inner wall of the air inlet cavity 37, the jet holes 38 are arranged in four rows, and the two rows of jet holes 38 on both sides are symmetrically arranged, an air pump 39 is fixedly connected to the upper end of the drying plate 36, the air pump 39 is connected to the air inlet cavity 37 through a plurality of air supply pipes 40, and the air pump 39 is connected to an external container storing hot air through a pipeline.

[0028] The drying mechanism further includes four blocks 41 (such as Figure 5 As shown), a plurality of second springs 42 are commonly fixedly connected between two adjacent stoppers 41, two rotating shafts 43 are symmetrically connected to the inner wall of the air inlet chamber 37 for rotation, and the side walls of the two rotating shafts 43 are fixedly connected to second cams 44, the side walls of the stoppers 41 slide against the second cams 44, and the protruding parts of the two second cams 44 are arranged in opposite directions, one end of the rotating shaft 43 passes through the first sliding groove 34 and is fixedly connected to the first gear 45, the upper end of the base 1 is fixedly connected to the first rack 46 through a fixed shaft, the first gear 45 is meshed with the first rack 46, and the slide rod 35 is fixedly connected to the push rod 31 through a fixed rod.

[0029] It should be noted that the four blocks 41 are arranged in groups of two, and the second cam 44 is located between a group of blocks 41 (eg Figure 5 as shown).

[0030] It should be noted that the number of rows of the jet holes 38 is the same as the number of the stoppers 41, and the jet holes 38 are not a uniform matrix. When the push rod 31 is extended to the limit, the states of the stoppers 41 and the jet holes 38 are as follows: Figure 5 As shown, at this time, the two rows of air injection holes 38 close to each other are completely blocked by the corresponding two stoppers 41, and the two rows of air injection holes 38 far away from each other are completely exposed.

[0031] It should be noted that, by setting the transmission ratio between the first gear 45 and the first rack 46 , the rotating shaft 43 can only rotate forward and backward 180 degrees during the reciprocating movement of the drying plate 36 .

[0032] Furthermore, the air pump 39 will pump the external hot air into the air inlet chamber 37 through the air supply pipe 40, and finally the hot air will be ejected through the multiple jet holes 38 to dry the composite electrolyte slurry on the composite electrolyte membrane. When the drying plate 36 moves toward the drying box 7, it will drive the rotating shaft 43 to move synchronously, and drive the first gear 45 to move. Since the first gear 45 is meshed with the first rack 46, the first gear 45 will rotate synchronously, driving the rotating shaft 43 to rotate, and then driving the second cam 44 to rotate, so that the two blocks 41 on both sides move to both sides, and the two blocks 41 in the middle also move to both sides, and then the two rows of jet holes 38 on both sides will be gradually blocked by the blocks 41, and the two rows of jet holes in the middle will be gradually blocked by the blocks 41. The hole 38 will gradually open, so in the process of the drying plate 36 moving closer to the drying box 7, the jet holes 38 will increase, and the diameter of the jet holes 38 will decrease, so the jet speed can be gradually increased. On the contrary, the jet speed is small when it is far away from the drying box 7. Since the composite electrolyte slurry has a large fluidity at the beginning, the small jet speed at the beginning can avoid the flow of the composite electrolyte slurry, thereby causing the composite electrolyte slurry on the composite electrolyte membrane to be uneven. As the drying proceeds, the composite electrolyte slurry gradually solidifies and the fluidity decreases. Therefore, the closer the composite electrolyte slurry is to the drying box 7, the smaller the fluidity is. Therefore, when the drying plate 36 is close to the drying box 7, the jet speed increases, which can increase the drying speed.

[0033] A leveling mechanism is installed on the drying plate 36, and the leveling mechanism includes a leveling plate 47 fixedly connected to the side wall of the drying plate 36 through a fixed shaft. The leveling plate 47 is U-shaped, and two leveling blocks 48 are symmetrically slidably connected to the inner wall of the leveling plate 47. Two reciprocating screws 49 are symmetrically rotatably connected to the inner wall of the leveling plate 47. The side walls of the two reciprocating screws 49 are respectively threadedly connected to the two leveling blocks 48. Two second slide grooves 50 are provided on the side wall of the preheating box 6. One end of the two reciprocating screws 49 passes through the second slide grooves 50 and is fixedly connected to two second gears 51. The upper end of the base 1 is fixedly connected to two second racks 52 through a fixed shaft, and the two second gears 51 are respectively meshed with the two second racks 52.

[0034] Furthermore, the composite electrolyte membrane entering the preheating box 6 will pass through the leveling plates 47, and the reciprocating movement of the push rod 31 will drive the sliding rod 35 to move back and forth, and then drive the drying plate 36 to move back and forth, and drive the leveling plate 47 to move back and forth, so as to level the composite electrolyte membrane. There may be wrinkles on the surface of the composite electrolyte membrane just after pressing, and the reciprocating movement of the leveling plate 47 will drive the reciprocating screw 49 to move horizontally, and then drive the second gear 51 to move horizontally. Since the second gear 51 is meshed with the second rack 52, the second gear 51 will rotate synchronously, and then drive the reciprocating screw 49 to rotate, so that the two leveling blocks 48 move back and forth, further improving the effect of eliminating wrinkles.

[0035] The side walls of the two first mounting plates 2 and the two third mounting plates 12 that are close to each other are rotatably connected to the first guide roller 53, the inner wall of the box body 4 is rotatably connected to the first guide roller 53, the inner wall of the drying box 7 is rotatably connected to multiple second guide rollers 54, and a ceramic infrared heater 57 is installed on the top of the drying box 7.

[0036] In the present invention, the first unwinding roller 3 is wound with silicone oil paper, the second unwinding roller 5 is wound with a supporting film, the silicone oil paper is wound around the first guide roller 53, the first coating roller 13, the pressing roller 56, the second coating roller 18 and the guide roller 9 in sequence, and then the end is fixed to the receiving roller 11, and the supporting film is wound around the first guide roller 53, the pressing roller 56 and the guide roller 9 in sequence, and then the end is fixed to the receiving roller 11, and the supporting film is located at the upper end of the silicone oil paper (such as Figure 3 as shown).

[0037] Then, the motor 22, the air pump 39 and the ceramic infrared heater 57 are started to drive the receiving roller 11 to rotate, and the motor 22 will synchronously drive the driving wheel 23 to rotate, and then drive the first driven wheel 24 and the second driven wheel 25 to rotate, and drive the first unwinding roller 3 and the second unwinding roller 5 to rotate. The rotation of the receiving roller 11 will reel up the electrolyte membrane, and the rotation of the first unwinding roller 3 and the second unwinding roller 5 will unwind the silicone oil paper and the support film, and then the whole device starts to operate. The rotation of the second unwinding roller 5 will drive the first cam 33 to rotate, and then the first cam 33 cooperates with the first spring 32 It will drive the push rod 31 to slide back and forth, and drive the sliding plug 27 to slide back and forth in a sealed manner. At this time, the external composite electrolyte slurry will be drawn into the sliding cylinder 26 through the one-way feed pipe 28, and then the composite electrolyte slurry will enter the first feed cavity 15 and the second feed cavity 20 through the first one-way discharge pipe 29 and the second one-way discharge pipe 30 respectively. The composite electrolyte slurry will be sprayed onto the A surface of the silicone oil paper through multiple first spray holes 16, and then when the silicone oil paper and the support film pass between the two pressing rollers 56, the silicone oil paper and the support film are pressed together, and then enter the preheating box 6 together.

[0038] The composite electrolyte membrane entering the preheating box 6 will pass through the leveling plates 47, and the reciprocating movement of the push rod 31 will drive the sliding rod 35 to move back and forth, and then drive the drying plate 36 to move back and forth, and drive the leveling plate 47 to move back and forth to level the composite electrolyte membrane. There may be wrinkles on the surface of the composite electrolyte membrane just after pressing, and the reciprocating movement of the leveling plate 47 will drive the reciprocating screw 49 to move horizontally, and then drive the second gear 51 to move horizontally. Since the second gear 51 is meshed with the second rack 52, the second gear 51 will rotate synchronously, and then drive the reciprocating screw 49 to rotate, so that the two leveling blocks 48 move back and forth, further improving the effect of eliminating wrinkles.

[0039] The air pump 39 will pump the external hot air into the air inlet chamber 37 through the air supply pipe 40, and finally the hot air will be ejected through the multiple jet holes 38 to dry the composite electrolyte slurry on the composite electrolyte membrane. When the drying plate 36 moves toward the direction close to the drying box 7, it will drive the rotating shaft 43 to move synchronously, and drive the first gear 45 to move. Since the first gear 45 is meshed with the first rack 46, the first gear 45 will rotate synchronously, driving the rotating shaft 43 to rotate, and then driving the second cam 44 to rotate, so that the two blocks 41 on both sides move to both sides, and the two blocks 41 in the middle also move to both sides, and then the two rows of jet holes 38 on both sides will be gradually blocked by the blocks 41, and the two rows of jet holes 38 in the middle will be gradually blocked by the blocks 41. 8 will gradually open, so in the process of the drying plate 36 moving closer to the drying box 7, the jet holes 38 will increase, and the diameter of the jet holes 38 will decrease, so the jet speed can be gradually increased. On the contrary, when away from the drying box 7, the jet speed is small. Since the composite electrolyte slurry has a large fluidity at the beginning, the small jet speed at the beginning can avoid the flow of the composite electrolyte slurry, thereby causing the composite electrolyte slurry on the composite electrolyte membrane to be uneven. As the drying proceeds, the composite electrolyte slurry gradually solidifies and the fluidity decreases. Therefore, the closer the composite electrolyte slurry is to the drying box 7, the smaller the fluidity. Therefore, when the drying plate 36 moves closer to the drying box 7, the jet speed increases, which can increase the drying speed.

[0040] When the composite electrolyte membrane moves out of the preheating box 6, multiple second spray holes 21 will spray the composite electrolyte slurry on the B side of the silicone oil paper, and then it will enter the drying box 7, and the ceramic infrared heater 57 will dry it again to finally form a complete composite electrolyte membrane, which will then be rolled up on the receiving roller 11.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
