Description

Technical Field

[0001] This utility model relates to the field of casting molding machine technology, and in particular to a continuous casting molding machine for perfluorinated proton exchange membranes. Background Technology

[0002] Perfluorinated proton exchange membranes (PEMs) are the heart material of fuel cells, responsible for conducting protons and isolating gases. Their performance directly affects the efficiency and lifespan of the battery. As the core equipment for PEM preparation, the continuous casting molding machine transforms perfluorinated resin into high-performance proton exchange membranes through a continuous process of solution casting, cooling curing, and precision molding.

[0003] If the resin solution is not pre-cooled, the temperature may remain at a high level. At this time, the solution viscosity is low and the fluidity is too strong. When it is directly cast onto the forming roller, it will spread out or even drip due to gravity, resulting in uneven film thickness or even failure to form a continuous film layer. To address the above problems, the following solutions are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a continuous casting machine for perfluorinated proton exchange membranes to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous casting molding machine for perfluorinated proton exchange membranes, comprising a main body, the main body further comprising a molding mechanism, a drive motor fixedly connected to the outer wall of the main body, a rotating rod rotatably connected to the inner wall of the main body, the rotating rod extending to the outside of the main body and fixedly connected to the output shaft of the drive motor, and a molding roller fixedly connected to the outer wall of the rotating rod.

[0006] Preferably, two support rods are fixedly connected to the top of the main body, and a shell is fixedly connected to the side of the two support rods that are close to each other.

[0007] Preferably, several inclined plates are fixedly connected to the inner wall of the housing, and two baffles are fixedly connected to the outer wall of the forming roller.

[0008] Preferably, a discharge plate is fixedly connected to the inner wall of the shell, and a discharge port is opened at the bottom of the discharge plate.

[0009] Preferably, the forming roller has several through grooves, and a cooling box is fixedly connected to the inner wall of the through grooves.

[0010] Preferably, a cooler is fixedly connected to the inner wall of the through groove, and a connecting pipe is fixedly connected to the side of the cooler away from the through groove. The end of the connecting pipe away from the cooler is fixedly connected to the cooling box.

[0011] Preferably, two connecting rods are fixedly connected to the outer wall of the main body, and a scraper is fixedly connected to the side of the two connecting rods that are close to each other.

[0012] Preferably, a collection box is provided below the scraper, and the bottom of the collection box is slidably connected to the main body.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this utility model:

[0015] 1. When using this molding machine, the resin solution is poured into the housing. Under the action of several inclined plates, as the resin solution flows onto the inclined plates, it falls in a Z-shape layer by layer after passing through multiple inclined plates. The extended path increases the residence time of the resin solution in the air, thereby effectively reducing the temperature of the resin solution and achieving a pre-cooling effect. This keeps the resin in a semi-solid state, avoiding complete solidification which would make casting difficult, and also reducing the load on the subsequent molding rollers, improving the molding efficiency of the resin solution on the molding rollers. After pre-cooling, the resin solution... The liquid flows through the outlet onto the outer wall of the forming roller. At this point, the drive motor is started, which drives the forming roller to rotate. With the combined use of the cooling box, the cooler, and the connecting pipe, the cooler cools the coolant in the cooling box through the connecting pipe. The cooled coolant is then transferred through the forming roller to the resin solution flowing onto the outer wall of the forming roller, thereby cooling the resin solution into the required exchange membrane. The semi-cured state can improve the uniformity of resin adhesion on the surface of the forming roller. By reducing the cooling pressure of the forming roller through pre-cooling, the rotation speed of the forming roller can be increased, thereby accelerating the casting speed and increasing production capacity.

[0016] 2. The baffle ensures that the width of the formed exchange membrane is consistent. During the rotation of the forming roller, it contacts the scraper, which removes the residue on the outer wall of the forming roller, preventing the resin residue from solidifying and sticking to the roller surface. This avoids the residue affecting the exchange membrane formed on the forming roller. The baffle prevents the exchange membrane from being scrapped due to width deviation, and the scraper prevents batch defects caused by residue contamination. This ensures the consistency of the exchange membrane during forming and the continuity of the forming machine in the production of exchange membranes. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6 The perfluorinated proton exchange membrane continuous casting molding machine shown includes a main body 101, which also includes a molding mechanism 1. A drive motor 102 is fixedly connected to the outer wall of the main body 101, and a rotating rod 103 is rotatably connected to the inner wall of the main body 101. The rotating rod 103 extends to the outside of the main body 101 and is fixedly connected to the output shaft of the drive motor 102. A molding roller 104 is fixedly connected to the outer wall of the rotating rod 103. Two support rods 105 are fixedly connected to the top of the main body 101. A housing 106 is fixedly connected to the side of the two support rods 105 that are close to each other. A molding roller 104 is fixedly connected to the inner wall of the housing 106. Several inclined plates 107 are fixedly connected. Two baffles 108 are fixedly connected to the outer wall of the forming roller 104. A discharge plate 109 is fixedly connected to the inner wall of the housing 106. A discharge port 110 is opened at the bottom of the discharge plate 109. Several through grooves 111 are opened inside the forming roller 104. A cooling box 112 is fixedly connected to the inner wall of the through groove 111. A cooler 113 is fixedly connected to the inner wall of the through groove 111. A connecting pipe 114 is fixedly connected to the side of the cooler 113 away from the through groove 111. The end of the connecting pipe 114 away from the cooler 113 is fixedly connected to the cooling box 112.

[0026] When using this molding machine, the resin solution is poured into the housing 106. Under the action of several inclined plates 107, as the resin solution flows onto the inclined plates 107, it flows down in a Z-shape layer by layer after passing through multiple inclined plates 107. The extended path increases the residence time of the resin solution in the air, thereby effectively reducing the temperature of the resin solution and achieving a pre-cooling effect. This keeps the resin in a semi-solid state, avoiding complete solidification which would make casting difficult, and also reducing the load on the subsequent molding roller 104, improving the molding efficiency of the resin solution on the molding roller 104. After pre-cooling, the resin solution flows to the molding roller through the discharge port 110. On the outer wall of 104, the drive motor 102 is started at this time. The drive motor 102 drives the forming roller 104 to rotate. With the combined use of the cooling box 112, the cooler 113 and the connecting pipe 114, the cooler 113 cools the coolant in the cooling box 112 through the connecting pipe 114. The cooled coolant is then transferred through the forming roller 104 to the resin solution flowing onto the outer wall of the forming roller 104, thereby cooling the resin solution into the required exchange membrane. The semi-cured state can improve the uniformity of resin adhesion on the surface of the forming roller. By reducing the cooling pressure of the forming roller 104 through pre-cooling, the rotation speed of the forming roller 104 can be increased, thereby accelerating the casting speed and increasing production capacity.

[0027] Two connecting rods 115 are fixedly connected to the outer wall of the main body 101. A scraper 116 is fixedly connected to the side of the two connecting rods 115 that are close to each other. A collection box 117 is provided below the scraper 116. The bottom of the collection box 117 is slidably connected to the main body 101.

[0028] Under the action of the baffle 108, the width of the formed exchange membrane can be ensured to be consistent. During the rotation of the forming roller 104, it contacts the scraper 116. The scraper 116 can scrape off the residue on the outer wall of the forming roller 104 to prevent the resin residue from solidifying and sticking to the roller surface, and avoid the residue from affecting the exchange membrane formed on the forming roller 104. The baffle 108 prevents the exchange membrane from being scrapped due to width deviation, and the scraper 116 avoids batch defects caused by residue contamination, which can ensure the consistency of the exchange membrane during forming and ensure the continuity of the forming machine in the production of exchange membranes.

[0029] The working principle of the perfluorinated proton exchange membrane continuous casting molding machine provided by this utility model is as follows: When using this molding machine, the resin solution is poured into the housing 106. Under the action of several inclined plates 107, when the resin solution flows onto the inclined plates 107, it flows down in a Z-shape layer by layer on the inclined plates 107 after passing through multiple inclined plates 107. The extended path increases the residence time of the resin solution in the air, thereby effectively reducing the temperature of the resin solution and achieving the effect of pre-cooling. This keeps the resin in a semi-solid state, avoiding complete solidification which would lead to casting difficulties, and also reducing the load on the subsequent forming roller 104, improving the efficiency of the resin solution forming on the forming roller 104. After pre-cooling, the resin... The solution flows through the outlet 110 onto the outer wall of the forming roller 104. At this time, the drive motor 102 is started, and the drive motor 102 drives the forming roller 104 to rotate. With the combined use of the cooling box 112, the cooler 113 and the connecting pipe 114, the cooler 113 cools the coolant in the cooling box 112 through the connecting pipe 114. The cooled coolant is then transferred through the forming roller 104 to the resin solution flowing onto the outer wall of the forming roller 104, thereby cooling the resin solution into the required exchange membrane. The semi-cured state can improve the uniformity of resin adhesion on the surface of the forming roller. By reducing the cooling pressure of the forming roller 104 through pre-cooling, the rotation speed of the forming roller 104 can be increased, thereby accelerating the casting speed and increasing production capacity.

[0030] Under the action of the baffle 108, the width of the formed exchange membrane can be ensured to be consistent. During the rotation of the forming roller 104, it contacts the scraper 116. The scraper 116 can scrape off the residue on the outer wall of the forming roller 104 to prevent the resin residue from solidifying and sticking to the roller surface, and avoid the residue from affecting the exchange membrane formed on the forming roller 104. The baffle 108 prevents the exchange membrane from being scrapped due to width deviation, and the scraper 116 avoids batch defects caused by residue contamination, which can ensure the consistency of the exchange membrane during forming and ensure the continuity of the forming machine in the production of exchange membranes.

This keeps the resin in a semi-solid state, preventing complete solidification which would hinder casting and reducing the load on the subsequent forming roller 104, thus improving the efficiency of resin solution forming on the forming roller 104. The pre-cooled resin solution then passes through… The material flows from the outlet 110 onto the outer wall of the forming roller 104. At this time, the drive motor 102 is started, and the drive motor 102 drives the forming roller 104 to rotate. With the combined use of the cooling box 112, the cooler 113 and the connecting pipe 114, the cooler 113 cools the coolant in the cooling box 112 through the connecting pipe 114. The cooled coolant is then transferred through the forming roller 104 to the resin solution flowing onto the outer wall of the forming roller 104, thereby cooling the resin solution into the required exchange membrane. The semi-cured state can improve the uniformity of resin adhesion on the surface of the forming roller. By reducing the cooling pressure of the forming roller 104 through pre-cooling, the rotation speed of the forming roller 104 can be increased, thereby accelerating the casting speed and increasing production capacity.

[0033] Under the action of the baffle 108, the width of the formed exchange membrane can be ensured to be consistent. During the rotation of the forming roller 104, it contacts the scraper 116.
