Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon-coated aluminum foil technology, specifically a water-adding device in the process of coating carbon-coated aluminum foil for electrodes. Background Technology
[0002] Carbon-coated aluminum foil is a composite material made by uniformly and finely coating dispersed nano-conductive graphite and carbon-coated particles onto the surface of aluminum foil as a base. This surface-treated aluminum foil reduces the contact resistance between the positive / negative electrode active materials and the current collector, and improves their adhesion properties, thus reducing the amount of binder needed and significantly enhancing the overall performance of the battery.
[0003] Currently, most carbon-coated aluminum foil manufacturers use roller coating technology, which involves placing the slurry in a tray and manually adding water to compensate for the evaporation of moisture and solvent. However, manually adding water not only makes it difficult to control the amount of water, but also increases the workload of workers. Furthermore, the concentration of the slurry will show a significant trend of change between each water addition, making it difficult to ensure the uniformity of the aluminum foil coating process and making it difficult for the product performance to meet high-quality requirements. Utility Model Content

[0007] Therefore, by pouring deionized water into the cylinder and allowing it to flow out through a transparent tube under gravity, automatic water addition is achieved. Furthermore, the flow rate adjustment mechanism allows for precise control of the water dosage, eliminating the need for frequent manual water addition and reducing labor costs. Continuous water addition also prevents significant changes in slurry concentration, ensuring uniformity during aluminum foil coating and meeting high-quality product performance requirements. Additionally, the filter screen removes impurities from the deionized water, guaranteeing slurry purity and improving product quality.
[0008] Furthermore, the flow rate regulating mechanism includes a mounting sleeve disposed on the outer surface of the transparent flexible tube, an air bladder disposed inside the mounting sleeve and the air bladder wrapping around the outer surface of the transparent flexible tube, a tube body disposed on the outer surface of the mounting sleeve, the tube body and the air bladder being connected by a connecting tube, a screw being threaded through the inside of the tube body, and a piston disposed inside the tube body and connected to the screw.
[0009] Furthermore, a brush plate is provided on the outer surface of the filter screen, and the outer surface of the brush plate is provided with bristles that are in contact with the filter screen. Guide rods are connected to both sides of the outer surface of the brush plate, and the ends of the two guide rods extend to the outside of the mounting block and are jointly installed with a pull block.
[0010] Furthermore, a top cover is hinged to the top of the filling hopper, and a handle is rotatably mounted on the outer surface of the filling hopper.
[0011] Furthermore, a U-shaped glass tube is connected to the bottom of the cylinder, and a connecting block is installed on the outer surface of the U-shaped glass tube, with the end of the connecting block connected to the cylinder.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.
[0023] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0024] Please see Figures 1-4The present invention provides a water addition device in the process of coating aluminum foil for carbon coating of electrodes, including a cylinder 100, a filling hopper 101 provided at the top of the cylinder 100, a transparent hose 102 connected to the bottom of the cylinder 100, a flow rate regulating mechanism 200 provided on the outer surface of the transparent hose 102, an installation block 103 installed on the outer surface of the transparent hose 102, a filter screen 104 provided inside the installation block 103, and the filter screen 104 is inclined, and a drain pipe 105 is connected to the lower outer surface of the installation block 103, and a drain valve 106 is provided inside the drain pipe 105.
[0025] In use, deionized water is poured into the cylinder 100 through the filling hopper 101. Under the influence of gravity, the deionized water flows out through the transparent hose 102, thus achieving automatic water addition. Furthermore, the flow rate adjustment mechanism 200 allows for precise control of the water dosage, avoiding frequent manual water additions, reducing labor costs. Continuous water addition also prevents significant changes in slurry concentration, ensuring uniformity during the aluminum foil coating process and meeting the required standards. The product performance meets high-quality requirements; and through the setting of filter screen 104, impurities in deionized water can be filtered, thereby ensuring the purity of the slurry and improving product quality. Since filter screen 104 is set at an angle, most of the impurities intercepted on its surface can be washed to its angled lower part by the flow of deionized water, thus ensuring the flowability of deionized water in filter screen 104, reducing the possibility of clogging, and reducing the impact on the flow rate of deionized water. When the drain valve 106 is opened, the impurities collected in the mounting block 103 can be discharged outward.
[0026] Specifically, the flow rate regulating mechanism 200 includes a mounting sleeve 201 disposed on the outer surface of the transparent flexible tube 102. An air bladder 202 is disposed inside the mounting sleeve 201 and wraps around the outer surface of the transparent flexible tube 102. A tube body 203 is mounted on the outer surface of the mounting sleeve 201. The tube body 203 and the air bladder 202 are connected via a connecting tube 206. A screw 204 is threaded through and threaded onto the inside of the tube body 203. A piston 205 is disposed inside the tube body 203 and connected to the screw 204. When the screw 204 is turned, due to its thread... The connection method allows the piston 205 to move back and forth within the tube 203. When the piston 205 moves toward the airbag 202, it can push the air inside the tube 203 into the airbag 202 through the connecting tube 206, causing it to expand and press against the outer surface of the transparent hose 102. This reduces the flow path inside the transparent hose 102, thereby regulating the flow rate. Furthermore, the airbag 202 evenly wraps around the outer surface of the transparent hose 102, resulting in uniform force on the transparent hose 102, minimizing damage and extending its service life.
[0027] Specifically, a brush plate 300 is provided on the outer surface of the filter screen 104. The outer surface of the brush plate 300 is provided with bristles, and the bristles are in contact with the filter screen 104. Guide rods 301 are connected to both sides of the outer surface of the brush plate 300. The ends of the two guide rods 301 extend to the outside of the mounting block 103 and are jointly installed with a pull block 302. Workers can periodically pull the pull block 302 to move it back and forth, so that it drives the brush plate 300 to move back and forth on the surface of the filter screen 104. The bristles are used to clean the surface of the filter screen 104, thereby further cleaning the impurities clogging the surface of the filter screen 104, ensuring the flowability of the filter screen 104, and avoiding affecting the flow rate of deionized water.
[0028] Specifically, a top cover 400 is hinged to the top of the filling hopper 101, and a handle 401 is rotatably installed on the outer surface of the filling hopper 101. With the top cover 400, water can be added into the cylinder 100 and then the top cover 400 can be closed to prevent dust from entering. With the handle 401, it is convenient to suspend the cylinder 100.
[0029] Specifically, a U-shaped glass tube 500 is connected to the bottom of the cylinder 100. A connecting block 501 is installed on the outer surface of the U-shaped glass tube 500, and the end of the connecting block 501 is connected to the cylinder 100. After the deionized water inside the cylinder 100 enters the U-shaped glass tube 500, the water level inside the cylinder 100 can be displayed, making it convenient to replenish water in a timely manner.
[0030] Specifically, a sealing ring is provided at the connection between the guide rod 301 and the mounting block 103. By providing the sealing ring, the sealing performance at the connection between the guide rod 301 and the mounting block 103 can be improved, thus preventing leakage.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
