Description

Technical Field

[0001] This application relates to the field of casting machine technology, and in particular to a casting machine. Background Technology

[0002] A casting machine is a piece of equipment used to produce thin film materials, widely used in many industries such as plastics, electronics, and food packaging. The following is a brief description of its working principle, structure, and applications: A fluid raw material with a certain viscosity (such as plastisol, ceramic slurry, polymer solution, etc.) is uniformly cast onto a continuously moving base belt (usually a steel or plastic belt) through a specific method (such as extrusion, gravity casting, etc.). As the base belt moves, the cast material gradually dries and solidifies under specific environmental conditions (such as controlled temperature and humidity), eventually forming a continuous thin film product, which is then peeled off from the base belt and wound up.

[0003] When processing certain special films using a casting machine, the equipment structure used is different due to the material requirements. For example, solvent-based polymer films, water-based ceramic / battery separators, biodegradable films, and optical functional films require drying treatment during the production process compared to ordinary films.

[0004] Current casting machines mainly use microwave heating for drying. After drying via microwave heating, the film is cooled and then coiled. Since microwave heating also heats the carrier film, the thermal efficiency is low and the heating time is relatively long. Furthermore, the drying, cooling, and coiling process prolongs the processing time, which is not conducive to improving processing efficiency. Therefore, this utility model proposes a casting machine to at least partially solve the problems that may exist in the prior art. Utility Model Content

[0005] In view of the aforementioned problems, this application is made in order to provide a casting machine that overcomes or at least partially solves the aforementioned problems.

[0006] A casting machine, comprising:

[0007] The support frame has an unwinding shaft at its first end and a first winding shaft and a second winding shaft for winding the target film at its second end.

[0008] The carrier film is located on the unwinding shaft and extends from the upper end of the support frame to the first take-up shaft;

[0009] The first end of the support frame is provided with a slurry hopper located above the carrier membrane; a scraper is provided at the outlet of the slurry hopper.

[0010] A drying mechanism is mounted on the upper end of a support frame and has at least one air outlet and one air exhaust outlet, as well as a microwave heating component facing the support frame.

[0011] And the air outlet is located at the front end of the exhaust port and the microwave heating component.

[0012] Optionally, the carrier film is a graphene composite carrier film or a liquid metal coating film.

[0013] Optionally, the air outlet has a "human" - shaped structure.

[0014] Optionally, the microwave heating components are distributed between the air outlet and the exhaust port.

[0015] Optionally, a hopper is further provided at the upper end of the slurry tank.

[0016] Optionally, a homogenizing mechanism is further included. The homogenizing mechanism has a homogenizing container, and the output port of the homogenizing container is connected to the slurry tank or the hopper through a fluid pump.

[0017] Optionally, a mixing mechanism is further included. The mixing mechanism has a stirring container;

[0018] The discharge port of the stirring container is connected to the homogenizing container.

[0019] This application has the following advantages:

[0020] In the embodiment of this application, through the support frame, a film unwinding roller is provided at its first end, a first film winding roller and a second film winding roller for winding the target film are provided at its second end; the carrier film is located on the film unwinding roller and extends from the upper end of the support frame to the first film winding roller; at the first end of the support frame, a slurry tank is provided at the carrier film end; a scraper is provided at the discharge port position of the slurry tank; a drying mechanism, covering the upper end of the support frame, and having at least one air outlet and an exhaust port thereon, and a microwave heating component facing the support frame; and the air outlet is located at the front end of the exhaust port and the microwave heating component. Through the ingenious layout of the equipment structure, components such as the film unwinding roller, film winding rollers, slurry tank, and scraper are reasonably arranged on the support frame, optimizing the material casting process. Placing the air outlet at the front end of the exhaust port and the microwave heating component can make more effective use of hot air, improve the heat transfer path, increase the heat efficiency, reduce the ineffective heating of the carrier film, and shorten the microwave heating time. At the same time, the optimized layout and the setting of the drying mechanism simplify the process from drying to winding, no longer requiring a complex cooling link, directly achieving rapid winding, greatly improving the processing efficiency, and effectively solving the problems of low heat efficiency and long processing time in the prior art. Description of the Drawings

[0021] To more clearly illustrate the technical solution of this application, the drawings used in the description of this application will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] In the attached diagram, 101 is the support frame; 102 is the slurry hopper; 103 is the scraper; 104 is the unwinding shaft; 105 is the carrier film; 106 is the first winding shaft; 107 is the second winding shaft; 108 is the hopper; 201 is the drying mechanism; 202 is the microwave heating assembly; 203 is the air outlet; and 204 is the exhaust vent. Detailed Implementation

[0024] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] Reference Figure 1 This application illustrates a casting machine according to an embodiment of the present application, comprising: a support frame 101, a first end having an unwinding shaft 104, a second end having a first winding shaft 106 and a second winding shaft 107 for winding a target film; a carrier film 105 located on the unwinding shaft 104 and extending from the upper end of the support frame 101 to the first winding shaft 106; a slurry hopper 102 located at the first end of the support frame 101 above the carrier film 105; a scraper 103 located at the outlet of the slurry hopper 102; a drying mechanism 201 covering the upper end of the support frame 101, and having at least one air outlet 203 and an exhaust outlet 204 thereon, and a microwave heating assembly 202 facing the support frame 101; and the air outlet 203 being located at the front end of the exhaust outlet 204 and the microwave heating assembly 202.

[0026] It should be noted that in this application, the "front end" refers to the direction of membrane travel, that is, the membrane support frame 101 moves from the first end to the second end and is wound up at the second end. The membrane first passes through the exhaust port 204 and then through the air outlet 203.

[0027] The aforementioned drying structure allows the produced film to be dried and cooled quickly. On one hand, the film is dried by microwave heating; on the other hand, air is blown onto the film through the air outlet 203 and discharged from the exhaust port 204. The airflow direction is opposite to the film's travel direction, which increases the relative airflow speed without needing to increase the airflow speed (equivalent to the film and airflow generating opposite relative motion). Moreover, the air outlet 203 is located at the front end of the microwave heating component 202, allowing the film to be cooled by the airflow through the air outlet 203 after passing through the microwave heating component 202. This eliminates the need for separate cooling of the film, improving drying efficiency and saving the cooling process, thus significantly increasing production efficiency. At the same time, since there is no need to use cooling rollers or other corresponding devices, equipment costs can also be saved.

[0028] The following will further describe one type of casting machine in various exemplary embodiments of this application.

[0029] In an embodiment of this application, a casting machine is provided, wherein the carrier film 105 is a graphene composite carrier film or a liquid metal coating film.

[0030] In this application, a graphene composite carrier film is preferably used. It possesses excellent surface activity and dispersibility, which helps raw materials (such as polymers, ceramic slurries, etc.) in the casting machine to be more uniformly distributed on the carrier film. For example, in the ceramic casting process, it enables ceramic particles to be more evenly dispersed in the slurry, thereby improving the density and uniformity of the final ceramic film and reducing defects and performance differences. Graphene's excellent thermal conductivity allows the carrier film to transfer heat more efficiently. In the casting machine drying system, it can accelerate the drying speed of the material and make the material heated more uniformly. For example, in the production of plastic film casting, it avoids uneven film performance caused by local overheating or undercooling, helping to produce high-quality films with consistent thickness and performance. Furthermore, the film has a microwave reflectivity of over 92%, therefore, when using microwave heating, the film can still maintain a low temperature; that is, heat is not absorbed by the graphene composite carrier film, thus improving thermal efficiency and being environmentally friendly.

[0031] On the other hand, graphene has a smooth surface and low surface energy. Composite it onto a carrier film can reduce the adhesion between the cast material and the carrier film. After film formation, it is easier to peel off from the carrier film, reducing the risk of film breakage. This also helps improve production efficiency by reducing the time and effort spent cleaning up adhered materials, thus contributing to increased productivity.

[0032] In an embodiment of the present application, the air outlet 203 has a "human" - shaped structure (not shown in the figure); the "human" - shaped air outlet 203 divides the air flow into two paths. One path is towards the position of the microwave heating component 202, and the other path is in the opposite direction, that is, the traveling direction of the film, and is blown out from the outlet position of the drying mechanism 201, which can further increase the cooling efficiency.

[0033] It should be noted that microwaves have good penetration through air. Most of the microwave energy will pass through the air flow at the air inlet and will not be absorbed by the air flow with a large amount of heat. Therefore, it basically does not affect the heating of the film (without considering the heat absorbed by evaporation), and even if the heat absorbed by evaporation affects the temperature, it is much lower than the process of accelerating drying by the air flow.

[0034] In an embodiment of the present application, as Figure 1 shown, the microwave heating component 202 is distributed between the air outlet 203 and the air exhaust port 204, so that the air flow entering from the air outlet 203 discharges moisture (water vapor) from the air exhaust port 204. In this process, the contact area between the air flow and the film can be increased, which is beneficial to the rapid evaporation of moisture from the film, thereby accelerating drying. Metal tension rollers can also be respectively arranged in front of the first take - up reel 106 and the second take - up reel 107, which can not only adjust the take - up tension, but also prevent the film surface from generating static electricity through its metal conductive characteristics.

[0035] In an embodiment of the present application, a hopper 108 is further provided at the upper end of the slurry tank 102; it is used to add materials to the slurry tank 102 through the hopper 108.

[0036] Furthermore, a homogenizing mechanism and a mixing mechanism (not shown in the figure) are further included. The homogenizing mechanism has a homogenizing container, and the output port of the homogenizing container is connected to the slurry tank 102 or the hopper 108 through a fluid pump, which is used to automatically feed the equipment, facilitating automation; the mixing mechanism has a stirring container; the discharge port of the stirring container is connected to the homogenizing container. Through the above - mentioned homogenizing mechanism and mixing mechanism, the above - mentioned casting machine can operate as a complete production line. After automatic mixing by the mixing mechanism and then treatment by the homogenizing mechanism, it automatically feeds the slurry tank 102. By setting corresponding operating parameters, such as the running speed, etc., through the control components on the equipment, the equipment can automatically process, saving labor.

Therefore, the appended claims are intended to be construed as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
