[0012] Preferably, a heater is provided on the inner wall of the limiting groove, and the heater is a rectangular strip structure.

[0013] Preferably, the limit blocks are used to start and control the heater to heat the cross-sections on both sides of the silicon steel long sheet, and two limit blocks are provided on the left and right sides of each fixed limit sheet.

[0014] The present invention provides a silicon steel sheet slitting device, which relates to intelligent manufacturing equipment industry technology and has the following beneficial effects: 1. The present invention is provided with a liquid coating mechanism, which can realize stable transmission of the silicon steel long sheet through the connecting plates on both sides of the silicon steel long sheet, and can also simultaneously complete the real-time grinding of the cross-section exposed after the longitudinal shearing of both sides of the silicon steel long sheet, and naturally grind the burrs evenly. In combination with the grinding strips inside the groove, the grinding density is further improved, so that the cross-section of the silicon steel long sheet is polished more evenly and with higher precision, avoiding the problem of the deviation of the cutting transmission caused by the large number of burrs on the side, which affects the stability of the transmission process. At the same time, the factory quality of the silicon steel long sheet after longitudinal shearing is also improved. 2. The present invention provides a coating mechanism. When the connecting disc rotates, it passes through the interior of the liquid storage tank below. The interior of the liquid storage tank is filled with antioxidant and rust-proof liquid in advance. Therefore, the surface of the connecting disc and each grinding strip in the inner wall of the groove will be contaminated with liquid. As the connecting disc is driven by the fixed limit plate to rotate and grind the cross-section of the silicon steel long sheet, an antioxidant coating is added to the polished surface in real time, thereby sealing the cross-section of the silicon steel long sheet for oxidation resistance and rust prevention, preventing it from rapid and frequent contact with air during the longitudinal shearing process, and solving the problem that the side of the silicon steel long sheet is easily oxidized during working transmission after longitudinal shearing. 3. The present invention provides a liquid coating mechanism. When the fixed limit plate rotates, the slight friction force causes the liquid storage box with the counterweight plate to shake to a certain extent. This shaking can cause the liquid in the liquid storage tank inside the liquid storage box to shake to a certain extent. The antioxidant and rust-proofing liquid is better mixed by continuous and slight shaking, avoiding the problem of the antioxidant and rust-proofing liquid in the liquid storage box being stagnant for a long time. The problem of the antioxidant and rust-proofing liquid being reduced in functionality due to precipitation. 4. The present invention provides a liquid coating mechanism. When the grinding strips inside the grooves are driven to rotate by the grooves and the connecting discs, the grinding strips are used to polish the cross-sections of the side surfaces of the silicon steel long sheets. At the same time, when they are lowered into the liquid storage tank, the liquid inside the liquid storage box is stirred. The numerous grinding strips further stir and mix the liquid in the liquid storage tank, making the liquids mix more evenly, thereby reducing the problem of uneven coating on the cross-sections on both sides of the silicon steel long sheets caused by uneven mixing. 5. The present invention provides a limiting film-forming mechanism. After the connected disc is polished and smeared with anti-rust liquid by the rolling shaft, it will pass through the limiting block on the right again. The side of the silicon steel long sheet is quickly heated by the internal heater, so that the liquid quickly dries and forms a film, forming an air-isolated anti-oxidation protective layer. At the same time, before the silicon steel long sheet enters the rolling shaft, it is heated by the heater in the limiting block on the left, completing the preheating of the cross-section on both sides of the silicon steel long sheet, so that the cross-section can have sufficient temperature to be polished by the connecting disc, achieving better polishing accuracy and stability while improving the film-forming speed of the anti-oxidation and anti-rust liquid. 6. The present invention sets a limit film forming mechanism, and the limit block connected to the connecting plate is placed on the outside of the silicon steel long sheet through the limit groove. The limit block's upper and lower positions limit the silicon steel long sheet, and the silicon steel long sheet can also limit the position of the limit block in the same way, giving the liquid storage box and the limit block a certain space to shake. However, under the restriction of the silicon steel long sheet, the limit block realizes a self-locking effect on the liquid storage box at a certain swing angle, preventing the liquid from accidentally spilling, further ensuring the stability and safety of the equipment operation, and then also ensuring the quality of the longitudinal shearing of the silicon steel long sheet; 7. The present invention sets a limit film-forming mechanism. When the liquid storage box is slightly shaken left and right, the rolling bar on the inner wall of the liquid storage tank will roll back and forth on the fixed slide bar due to the inertia of the left and right swing, thereby quickly spreading and breaking up the viscous precipitates attached to the bottom layer of the inner wall of the liquid storage tank, and further utilizing the shaking effect to improve the mixing uniformity of the mixed liquid.

[0017] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a silicon steel sheet slitting device, comprising a slitting machine 1, a motor 5 fixedly connected to one side of the slitting machine 1, a rolling shaft 2 fixedly connected to the output end of the motor 5, one end of the rolling shaft 2 passes through the interior of the slitting machine 1 and is rotatably connected to the other side of the slitting machine 1 through a bearing, the outer wall of the rolling shaft 2 contacts a silicon steel long sheet 6, and the outer wall of the rolling shaft 2 is provided with a liquid coating mechanism 3; The coating mechanism 3 includes: The fixed limiting piece 301 is a circular sheet structure. The inner wall of the fixed limiting piece 301 is fixedly connected to the outer wall of the rolling shaft 2. A connecting plate 302 is fixedly connected to one side of the fixed limiting piece 301. A groove 303 is provided on the inner wall of the connecting plate 302. The connecting plate 302 serves to limit the position of the silicon steel long piece 6. The grinding bar 304 is a circular rod-shaped structure. One end of the grinding bar 304 is fixedly connected to the inner wall of the groove 303. The connecting plate 302 is a circular hollow disc-shaped structure. The grinding bar 304 plays the role of polishing the silicon steel long sheet 6; After the silicon steel long sheet 6 is longitudinally cut, it is transferred to the rolling shaft 2, and the motor 5 is started to control the rolling shaft 2 to continue rotating, and the silicon steel long sheet 6 is further transferred to the rear, thus completing a series of processes of longitudinally cutting the silicon steel long sheet 6. At this time, when the silicon steel long sheet 6 is tightened and transmitted by the rolling shaft 2, the silicon steel long sheet 6 will be separated by the left and right fixed limit pieces 301 on the rolling shaft 2, so that the silicon steel long sheet 6 can be transmitted stably without the left and right deviation and confusion. At the same time, the grooves 303 provided on the connecting plates 302 on both sides of the fixed limit pieces 301 can be used to realize the stable transmission of the silicon steel long sheet 6 through the connecting plates 302 on both sides of the silicon steel long sheet 6. The cross-sectional surface exposed after the longitudinal shearing of the silicon steel long sheet 6 on both sides can also be polished in real time at the same time, and the burrs can be naturally polished evenly. In combination with the polishing strips 304 inside the grooves 303, the polishing density can be further improved, so that the cross-sectional surface of the silicon steel long sheet 6 can be polished more evenly and with higher precision, avoiding the problem of more burrs on the side affecting the stability during the transmission process and causing the problem of deviation in the cutting and transmission, and also improving the factory quality of the silicon steel long sheet 6 after the longitudinal shearing. Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: During the slitting and subsequent transportation processes, the cross-section of the silicon steel sheet is frequently exposed to air. Due to the characteristics of silicon steel, the cross-section is easily oxidized by oxygen in the air, resulting in rust on the cross-section. This not only reduces the quality and performance of the silicon steel sheet, affecting its subsequent use, but also may shorten the product's service life and increase the company's production costs. Currently, antioxidant treatment of the cross-section of long silicon steel sheets typically requires transferring the sheet to specialized coating equipment after slitting. This approach not only increases the complexity and time cost of the production process, but can also cause secondary damage to the sheet during transfer, compromising product integrity.

[0018] When treating the cross-section of a long silicon steel sheet with an antioxidant and rust-proofing liquid, precipitation is prone to occur due to the liquid remaining in a static state for extended periods. This precipitation can lead to uneven distribution of the liquid's active ingredients, resulting in uneven application of the liquid to the cross-section. This not only compromises the antioxidant and rust-proofing effectiveness but can also leave portions of the cross-section unprotected, posing a risk of oxidation. Therefore, a sliding bar 305 is fixedly attached to the outer wall of the fixed stopper 301. The sliding bar 305 is an annular strip structure.

[0019] The fixed limiting piece 301 is slidably connected to a liquid storage box 306 via a sliding bar 305. The liquid storage box 306 is a rectangular box-shaped structure. A counterweight plate 308 is fixedly connected to the bottom of the liquid storage box 306. The counterweight plate 308 acts as a counterweight.

[0020] The inner wall of the liquid storage box 306 is provided with a liquid storage tank 307, and the liquid storage tank 307 is filled with an antioxidant and rust-proof liquid; When the connecting disc 302 rotates, it passes through the interior of the liquid storage tank 307 below, and the interior of the liquid storage tank 307 is filled with antioxidant and rust-proof liquid in advance, so the surface of the connecting disc 302 and each grinding strip 304 in the inner wall of the groove 303 will be contaminated with liquid. As the connecting disc 302 is driven by the fixed limiting piece 301 to rotate and grind the cross-section of the silicon steel long sheet 6, an antioxidant coating is added to the polished surface in real time, thereby sealing the cross-section of the silicon steel long sheet 6 to prevent oxidation and rust, so that it will not be quickly and frequently exposed to air during the longitudinal shearing process, which can solve the problem that the side of the silicon steel long sheet 6 is easily oxidized during work and transportation after longitudinal shearing; The counterweight of the counterweight plate 308 allows the liquid storage box 306 to be suspended below the fixed limiting piece 301 through the sliding bar 305 and be slidably connected to the fixed limiting piece 301. The rotation of the fixed limiting piece 301 will not affect the static state of the liquid storage box 306 and the counterweight plate 308 below. The friction of the sliding connection between them is very low, and the mutual influence is small. However, when the fixed limiting piece 301 rotates, the slight friction will cause the liquid storage box 306 with the counterweight plate 308 to shake to a certain extent. This shaking can cause the liquid in the liquid storage tank 307 inside the liquid storage box 306 to shake to a certain extent, so that the antioxidant and rust-proofing liquid can be better mixed by constantly and slightly shaking it, thereby avoiding the problem of the antioxidant and rust-proofing liquid being reduced in functionality due to precipitation of the antioxidant and rust-proofing liquid in the liquid storage box 306 due to long-term static state. When the grinding strips 304 in the groove 303 are driven to rotate by the groove 303 and the connecting plate 302, the grinding strips 304 are used to polish the cross-section of the side surface of the silicon steel long sheet 6. At the same time, when they descend into the liquid storage tank 307, they can complete the stirring of the liquid inside the liquid storage box 306. The numerous grinding strips 304 further stir and mix the liquid in the liquid storage tank 307, so that the liquids are mixed more evenly, reducing the problem of uneven smearing on the cross-sections on both sides of the silicon steel long sheet 6 caused by uneven mixing. Example 3: Please refer to Figure 1-12 , based on Example 1 and Example 2, the present invention provides a technical solution: when the cross-section of a silicon steel long sheet is heated, it is difficult to ensure the uniformity of heating using traditional heating methods. Since the thickness of the silicon steel long sheet may vary, and the relative position relationship between the heater and the cross-section, it is easy to cause local over- or underheating of the cross-section, affecting the antioxidant treatment effect and the polishing quality. At the same time, during the processing, the equipment may be subject to accidental collisions or vibrations, causing the liquid storage box and other components to shake, which may cause the anti-rust liquid to spill, not only causing a waste of resources, but also causing equipment failure and safety hazards. At the same time, the precipitation problem of the anti-rust liquid will also affect its performance and use effect. If it cannot be solved in time, the product quality will be further reduced. Therefore, a limited film-forming mechanism 4 is provided on the outer wall of the counterweight plate 308. The limited film-forming mechanism 4 includes a connecting plate 401, and one end of the connecting plate 401 is fixedly connected to a limited block 403. The limited block 403 is a block structure; The connecting plate 401 is an arc-shaped plate structure. A through groove is provided on the inner wall of the connecting plate 401 . A fixed shaft 402 is fixedly connected to the inner wall of the through groove. The fixed shaft 402 supports and fixes the connecting plate 401 . The through groove is used to reduce the weight of the connecting plate 401 .

[0021] A limiting groove 405 is provided on the inner wall of the limiting block 403 , and the long silicon steel sheet 6 is arranged in the inner wall of the limiting groove 405 .

[0022] The limiting groove 405 is a square groove, the fixed shaft 402 is a circular columnar structure, and the fixed shaft 402 is fixedly connected to the center position of the inner wall of the connecting plate 401.

[0023] A heater 404 is provided on the inner wall of the limiting groove 405 , and the heater 404 is a rectangular strip structure.

[0024] The limit block 403 is used to start and control the heater 404 to heat the cross-sections on both sides of the silicon steel long sheet 6. Two limit blocks 403 are provided on the left and right sides of each fixed limit piece 301; A fixed slide bar 407 is fixedly connected to the bottom of the inner wall of the liquid storage tank 307, and a rolling bar 406 is provided on the top of the fixed slide bar 407. A dovetail groove is provided on the outer wall of the rolling bar 406, and the outer wall of the rolling bar 406 is slidably connected to the outer wall of the fixed slide bar 407 through the dovetail groove; 4. The rust preventive measures of the present invention are as follows: The limit block 403 is connected to the counterweight plate 308 through the connecting plate 401. The counterweight lower connecting plate 401 of the counterweight plate 308 and the limit block 403 also maintain a certain stable state. At the same time, with a certain slight shaking of the liquid storage box 306, the limit block 403 can also shake slightly, allowing the heater 404 in the internal limit groove 405 to move up and down slightly, ensuring that the cross-section of the side of the silicon steel long piece 6 passing through the limit groove 405 can be fully and stably heated by the heater 404, avoiding the occurrence of uneven heating due to angles or different thicknesses of the silicon steel long piece 6. At the same time, when the silicon steel long piece 6 continuously passes through the limit groove 405 for the transmission and cutting work, it will also avoid accidents caused by the processing work or the liquid storage box 30 6 is touched, resulting in the problem that the liquid storage box 306 is shaken violently and slides and topples on the sliding bar 305 to spill the liquid. Because the limit block 403 connected to the connecting plate 401 is placed on the outside of the silicon steel long sheet 6 through the limit groove 405, the upper and lower positions of the limit block 403 limit the silicon steel long sheet 6, and the silicon steel long sheet 6 can also limit the position of the limit block 403 in the same way, so that the liquid storage box 306 and the limit block 403 can shake through a certain space. However, under the restriction of the silicon steel long sheet 6, the limit block 403 realizes the self-locking effect of a certain swing angle of the liquid storage box 306, preventing the liquid from accidentally spilling, and further ensuring the stability and safety of the equipment operation, and then also ensuring the longitudinal cutting processing quality of the silicon steel long sheet 6; When the liquid storage box 306 is slightly shaken left and right, the rolling bar 406 on the inner wall of the liquid storage tank 307 will roll back and forth on the fixed slide bar 407 due to the inertia of the left and right swing, thereby quickly spreading and breaking up the viscous sediment attached to the bottom layer of the inner wall of the liquid storage tank 307, and further utilizing the shaking effect to improve the mixing uniformity of the mixed liquid.
