Description

Technical Field

[0001] This utility model relates to the field of carbon foil technology, specifically a demagnetizing device for the material tank of a gravure coating machine. Background Technology

[0002] Carbon-coated foil is a composite foil with a layer of conductive paste composed of binder and conductive material uniformly coated on the surface of aluminum or copper current collector. It is mainly used to improve the conductivity, cycle life and stability of batteries and is widely used in the electronics and energy fields such as lithium batteries.

[0003] As a crucial component of batteries, carbon-coated aluminum foil has stringent requirements regarding the magnetic materials used. Therefore, demagnetization is particularly important in all stages of carbon-coated aluminum foil production. Traditional demagnetization processes primarily rely on pipeline demagnetizers used in the conductive paste production process. However, this method lacks a demagnetization device in the gravure coating area, leading to interactions between the gravure roller and the doctor blade, as well as the generation of metal debris during pipeline transport, which negatively impacts battery performance. Utility Model Content

[0004] The purpose of this invention is to provide a demagnetizing device for the material trough of a gravure coating machine, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A demagnetizing device for a material trough of a gravure coating machine includes a material trough. A U-shaped plate is installed on one side of the material trough along its length via a reciprocating motion mechanism. Two mounting plates are provided on the outer side of the U-shaped plate. Magnetic rods are provided on the outer surface of the mounting plates. A sleeve is fitted on the outer surface of the magnetic rods, and the sleeves are threadedly connected to the magnetic rods. Four feed holes are evenly provided at the bottom of the material trough. Mixing mechanisms are provided on both outer surfaces of the material trough.

[0007] Therefore, by using a magnetic rod and a sleeve, the magnetic properties of the magnetic rod act on the outer surface of the sleeve, thus adsorbing magnetic impurities in the slurry. This helps reduce the risk of magnetic substances on the carbon-coated foil, improving product quality. Furthermore, after the magnetic rod is removed from the sleeve, the magnetism on the sleeve surface disappears, allowing the magnetic impurities on the sleeve to be washed away, facilitating subsequent re-entry into the work and improving work efficiency. The reciprocating motion mechanism drives the sleeve to swing back and forth in the slurry, stirring the slurry. The mixing mechanism transports freshly added slurry from the bottom to the surface, further improving the uniformity of the slurry. This allows the sleeve to come into contact with more slurry, resulting in better adsorption of magnetic impurities.

[0008] Furthermore, the reciprocating motion mechanism includes two side plates mounted on the outer surface of the feed trough, a reciprocating screw rotatably mounted between the two side plates, a drive block mounted on the outer surface of the reciprocating screw, a limit rod connected between the two side plates, and the drive block slidably mounted on the outer surface of the limit rod. A motor is mounted on the outer surface of one side plate, and the end of the motor output shaft is connected to the reciprocating screw.

[0009] Furthermore, the mixing mechanism includes a circulating material pump installed on the outer surface of the material trough and near the bottom. The output end of the circulating material pump is connected to a conveying pipe, and the end of the conveying pipe is connected to the outer surface of the material trough near its top. A valve is installed inside the conveying pipe.

[0010] Furthermore, the outer surface of the U-shaped plate is provided with a groove, and the outer surface of the mounting plate is equipped with a slider that is compatible with the groove.

[0011] Furthermore, the outer surface of the mounting plate has multiple mounting grooves, and the end of the magnetic rod is fitted with a mounting block, which is fixed in the mounting groove by bolts.

[0012] Furthermore, a fixing disc is provided on the outer surface of the sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0014] 1. This utility model uses a magnetic rod and a sleeve. The magnetic force of the magnetic rod acts on the outer surface of the sleeve, thus adsorbing magnetic impurities in the slurry. This helps reduce the risk of magnetic substances on the carbon foil, improves product quality, and after the magnetic rod is pulled out of the sleeve, the magnetism on the sleeve surface disappears, allowing the magnetic impurities on the sleeve to be washed away, facilitating subsequent re-entry into the work and improving work efficiency.

[0015] 2. This utility model, through the setting of the reciprocating motion mechanism, can drive the sleeve to swing back and forth in the slurry, which can play a stirring role in the slurry. Furthermore, through the setting of the mixing mechanism, the freshly added slurry at the bottom can be transported to the surface, further improving the uniformity of the slurry. This allows the sleeve to come into contact with more slurry, resulting in a better adsorption effect on magnetic impurities. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. 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.

[0024] 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.

[0025] Please see Figures 1-5This utility model provides a demagnetizing device for a material trough of a gravure coating machine, including a material trough 100. A U-shaped plate 101 is installed on one side of the material trough 100 along its length via a reciprocating motion mechanism 200. Two mounting plates 102 are provided on the outer side of the U-shaped plate 101. A magnetic rod 103 is provided on the outer surface of the mounting plate 102. A sleeve 104 is fitted on the outer surface of the magnetic rod 103, and the sleeve 104 and the magnetic rod 103 are connected by threads. Four feed holes 105 are evenly opened at the bottom of the material trough 100. A mixing mechanism 300 is provided on both outer surfaces of the material trough 100.

[0026] In use, the coating roller is installed above the material tank 100, and the feed pipe is connected to the feed hole 105 at the bottom of the material tank 100. The feed pipe continuously feeds fresh slurry into the material tank 100. During use, the reciprocating motion mechanism 200 drives the two mounting plates 102 to reciprocate, allowing the sleeve 104 to contact more slurry and cover a larger area. During this process, due to the magnetic effect of the magnetic rod 103, a certain magnetic force is generated on the outer surface of the sleeve 104, which can attract magnetic impurities in the slurry to the sleeve 104. When it is necessary to clean the adsorbed impurities on the outer surface of the sleeve 104, simply remove the mounting plate 102 from the slurry tank 100, and then pull the magnetic rod 103 out of the sleeve 104 to make the magnetism on the surface of the sleeve 104 disappear. This will clean the magnetic impurities on the sleeve 104, making it easier to re-enter the work and improve work efficiency. It is worth noting that the magnetic field strength on the outer surface of the sleeve 104 should be greater than 10000GS. Of course, if the magnetic field strength is less than 10000GS, the adsorption effect on magnetic impurities will decrease, but demagnetization can still be achieved.

[0027] Specifically, the reciprocating motion mechanism 200 includes two side plates 201 mounted on the outer surface of the feed trough 100. A reciprocating screw 204 is rotatably mounted between the two side plates 201. A drive block 203 is mounted on the outer surface of the reciprocating screw 204. A limit rod 202 is connected between the two side plates 201, and the drive block 203 is slidably mounted on the outer surface of the limit rod 202. A motor 205 is mounted on the outer surface of one side plate 201. The end of the output shaft of the motor 205 is connected to the reciprocating screw 204. When the motor 205 is started, it drives the reciprocating screw 204 to rotate. Since the limit rod 202 limits the drive block 203, the drive block 203 can reciprocate along the length of the reciprocating screw 204, thereby driving the two sleeves 104 to reciprocate in the slurry.

[0028] Specifically, the mixing mechanism 300 includes a circulating material pump 301 installed on the outer surface of the material tank 100 near the bottom. The output end of the circulating material pump 301 is connected to a conveying pipe 302, and the end of the conveying pipe 302 is connected to the outer surface of the material tank 100 near its top. A valve 303 is installed inside the conveying pipe 302. When the circulating material pump 301 is started, it conveys the freshly added slurry at the bottom of the material tank 100 to the surface of the slurry through the conveying pipe 302, further improving the uniformity of the slurry. The valve 303 can control the flow of liquid.

[0029] Specifically, the outer surface of the U-shaped plate 101 is provided with a groove 400, and the outer surface of the mounting plate 102 is provided with a slider 401. The slider 401 is adapted to the groove 400. Through the setting of the groove 400 and the slider 401, the mounting plate 102 can be quickly disassembled and assembled, improving the cleaning efficiency of the sleeve 104 surface.

[0030] Specifically, the outer surface of the mounting plate 102 is provided with multiple mounting grooves 500, and the end of the magnetic rod 103 is equipped with a mounting block 501. The mounting block 501 is fixed in the mounting groove 500 by bolts. By setting the mounting groove 500 and the mounting block 501, an appropriate number of magnetic rods 103 can be set on the outer surface of the mounting plate 102 according to the actual production situation to ensure the demagnetization effect of the slurry and improve product quality.

[0031] Specifically, a fixing plate 600 is provided on the outer surface of the sleeve 104. Since the sleeve 104 and the magnetic rod 103 are connected by threads, the fixing plate 600 makes it easy to rotate the sleeve 104 to disassemble and assemble, reducing the chance of slipping.

[0032] 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.
