Description

Technical Field

[0001] This invention relates to the field of silicon steel strip processing technology, and discloses a silicon steel strip insulating coating machine and coating method. Background Technology

[0002] Silicon steel strip is a type of steel strip material with many excellent properties and is widely used in fields such as power electronics. During the production process of silicon steel strip, a coating is applied to its surface to protect it and prevent damage from oxidation and corrosion.

[0003] Currently, during the coating process of silicon steel strip, impurities are easily generated on the surface of the silicon steel strip during production. If these impurities are not cleaned, they will affect the coating itself, impacting the coating's protective ability and its bonding strength with the silicon steel strip. This can cause the coating to easily detach from the silicon steel strip, and both of these negative effects will significantly reduce the protective effect of the coating on the silicon steel strip, resulting in a high risk of damage to the silicon steel strip. Therefore, it is necessary to invent a coating machine that can remove impurities on the silicon steel strip before coating. Summary of the Invention

[0004] The present invention addresses the problems mentioned in the background art by providing a silicon steel strip insulating coating machine and coating method, aiming to better coat the silicon steel strip with the coating.

[0005] Technical solution: A silicon steel strip insulation coating machine and coating method, comprising: a frame; a guide roller rotatably connected to the frame; a bracket B fixedly connected to the frame; a cleaning roller slidably connected to the bracket B, through which the silicon steel strip passes; a rotating component connected to the bracket B, the rotating component being connected to the cleaning roller; a moving component A connected to the bracket B, the moving component A being connected to the cleaning roller; a support rod fixedly connected to the frame; an additive device disposed on the support rod; and extrusion rollers rotatably connected to the frame, the extrusion rollers being close to each other.

[0006] The moving component A includes: a cleaning roller with a threaded section that is threadedly connected to a bracket B; a limiting groove on each cleaning roller and a connecting ring rotatably connected to the limiting groove of each cleaning roller; and a rotating frame rotatably connected to the bracket B, with the connecting ring slidably connected to the upper and lower ends of the rotating frame.

[0007] As a further improvement of the present invention, the rotating assembly includes: a transmission wheel rotatably connected to the bracket B, each cleaning roller having a groove section, and each transmission wheel being slidably connected to the groove section of each cleaning roller; a transmission belt wound between the transmission wheels; a motor A fixedly connected to the bracket B; and a gear A rotatably connected to the bracket B and fixedly connected to the output end of the motor A, the two gears A meshing with each other, and the gear A located on the bracket B being coaxially fixed with one of the transmission wheels.

[0008] As a further improvement of the present invention, the additive is slidably connected to the support rod; it also includes: a tank disposed on the frame, the tank containing paint; a delivery pipe fixedly connected between the additive and the tank, the delivery pipe connecting the additive and the tank; and a movable component B connected to the frame, the movable component B being connected to the additive.

[0009] As a further improvement of the present invention, the moving component B includes: a functional roller rotatably mounted on a frame, the functional roller being driven to rotate by a movable silicon steel belt, the functional roller having a spiral groove that is connected end to end; and a connecting rod connecting the functional roller and the additive, one end of the connecting rod being slidably connected to the groove of the functional roller, and the other end being fixedly connected to the additive.

[0010] As a further improvement of the present invention, it also includes: a groove rail fixedly connected to the frame, wherein one of the extrusion rollers is slidably connected to the groove rail; and a movable component C connected to the frame, wherein the movable component C is connected to the extrusion roller.

[0011] As a further improvement of the present invention, the moving component C includes: a gear B rotatably connected to the frame; a rack slidably connected to the frame, the rack meshing with the gear B, and the rack rotatably connected to the extrusion roller slidably connected to the groove rail; and a motor B fixedly connected within the frame, the output end of the motor B being fixed to the gear B.

[0012] As a further improvement of the present invention, at least two sets of the aforementioned guide rollers, cleaning rollers, additives, extrusion rollers, and all corresponding associated components are provided on the frame.

[0013] As a further improvement of the present invention, the specific steps for using the silicon steel strip insulation coating machine are as follows:

[0014] S1. First, the silicon steel strip is passed through two cleaning rollers and around two guide rollers in sequence. Then, motor B is started to control the two extrusion rollers to separate and pass the silicon steel strip through the extrusion rollers. After that, motor B is reversed to control the two extrusion rollers to come closer together, thus completing the loading of the silicon steel strip into the silicon steel strip insulation coating machine.

[0015] S2. Start motor A to control the cleaning roller to rotate and move in a staggered manner. The cleaning roller removes impurities attached to the silicon steel strip passing through it.

[0016] S3. Start the additive to add paint onto the silicon steel belt. The functional roller is rotated by the moving silicon steel belt, while the control additive moves back and forth. The extrusion roller flattens the paint coated on the silicon steel belt that passes through it.

[0017] S4. Finally, after completing the coating process of the silicon steel strip, turn off motor A.

[0018] The beneficial effects of this invention are as follows: By incorporating a rotatable and staggered cleaning roller, this invention thoroughly removes impurities adhering to the silicon steel strip, resulting in a more stable and uniform bonding of the subsequent coating to the surface of the silicon steel strip, thereby improving the coating quality and ensuring the coating's ability to protect the silicon steel strip. Furthermore, by incorporating a back-and-forth movable applicator, this invention allows the coating to be evenly applied to the silicon steel strip. Combined with the leveling effect of the extrusion roller, this improves the uniformity of the coating application, ensuring the silicon steel strip is fully protected by the coating. Finally, the invention features controllable, separate extrusion rollers, making the process of the silicon steel strip passing through the extrusion rollers more convenient and improving the ease of use of this invention.

Detailed Implementation

[0028] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this invention in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this invention and are therefore intended only as examples, not as limiting the scope of protection of this invention.

[0029] Example: A silicon steel strip insulation coating machine, see reference. Figures 1-2 The system includes: a frame 1, which is the main body of the silicon steel strip insulation coating machine; a base plate 101 fixedly installed at the bottom of the frame 1; a bracket A102 fixedly installed at the top of the frame 1; guide rollers 2 rotatably installed on the bracket A102 and the frame 1, which guide the silicon steel strip into the silicon steel strip insulation coating machine; two guide rollers 2 are provided on the bracket A102 and the frame 1; a bracket B104 fixedly installed at the top of the frame 1; a cleaning mechanism installed on the bracket B104, which removes impurities from the silicon steel strip before coating; a support rod 103 fixedly installed in the middle of the frame 1; a feeding mechanism installed on the frame 1 and the support rod 103, which evenly adds coating to the surface of the silicon steel strip; and a leveling mechanism installed at the bottom of the frame 1, which evenly spreads the coating to ensure that the thickness of the coating is consistent at all locations.

[0030] See Figures 1-2 The frame 1 is equipped with two sets of guide rollers 2, cleaning mechanism, feeding mechanism and leveling mechanism as described above. The two sets are symmetrically distributed on the left and right sides of the frame 1, so that the silicon steel strip insulation coating machine can coat two units of silicon steel strips at the same time.

[0031] See Figure 1 , Figure 3 and Figure 4The cleaning mechanism includes: two cleaning rollers 3 slidably mounted on the bracket B104, with a silicon steel strip passing between the two cleaning rollers 3. The rotating cleaning rollers 3 remove impurities attached to the silicon steel strip before coating, reducing the impact of impurities on the coating protection function; a rotating component mounted on the bracket B104, which is connected to the cleaning rollers 3 and controls their rotation; and a moving component A mounted on the bracket B104, which is connected to the two cleaning rollers 3 and controls their staggered back-and-forth movement.

[0032] See Figure 1 , Figure 3 and Figure 4 The rotating assembly includes: two drive wheels 304 rotatably mounted on the bracket B104, each of the cleaning rollers 3 having a groove section 307, and the inner ring of each drive wheel 304 having a protrusion that is slidably connected to the groove section 307 of each cleaning roller 3. Through the insertion engagement of the protrusion and the groove section 307, the drive wheel 304 can control the rotation of the cleaning roller 3, and the cleaning roller 3 and the drive wheel 304 can move relative to each other; a drive belt 305 wound between the two drive wheels 304 to enable them to rotate synchronously; a motor A308 fixedly mounted on the bracket B104; and gears A309 rotatably mounted on the bracket B104 and fixedly connected to the output end of the motor A308. The two gears A309 mesh with each other, and the gear A309 on the bracket B104 is coaxially fixed with the drive wheel 304 below.

[0033] See Figures 3-4 The moving component A includes: a threaded section 306 on the upper cleaning roller 3, which is threadedly connected to the bracket B104, so that the upper cleaning roller 3 moves back and forth relative to the bracket B104 when it rotates; each cleaning roller 3 has a limiting groove 302, and a connecting ring 301 is rotatably installed on the limiting groove 302 of each cleaning roller 3. The connecting ring 301 and the cleaning roller 3 can rotate relative to each other and move back and forth synchronously. The two connecting rings 301 have protrusions on both sides; a rotating frame 303 is rotatably installed on the bracket B104. The upper and lower ends of the rotating frame 303 have sliding grooves. The protrusions of the two connecting rings 301 are slidably connected to the sliding grooves at the upper and lower ends of the rotating frame 303, respectively. The rotation of the rotating frame 303 enables the two cleaning rollers 3 to move back and forth synchronously, but the directions of movement are staggered.

[0034] The motor A308 is started. The motor A308 controls the rotation of two transmission wheels 304 through gear A309 and transmission belt 305, which in turn controls the rotation of two cleaning rollers 3 to remove impurities attached to the silicon steel belt. During the rotation of the cleaning rollers 3, the upper cleaning roller 3 moves back and forth due to the meshing action of the threaded section 306 and the bracket B104. When the cleaning roller 3 moves forward, it drives the connecting ring 301 on it to move forward, and the rotating frame 303 is rotated. Its lower end controls the cleaning roller 3 to move backward. Conversely, when the upper cleaning roller 3 moves backward, the lower cleaning roller 3 moves forward, thereby achieving the opposite movement direction of the two cleaning rollers 3.

[0035] See Figures 5-6 The feeding mechanism includes: an additive 4 slidably mounted on a support rod 103, the additive 4 having a built-in suction pump, the additive 4 being used to add coating to the silicon steel strip; a placement seat 401 fixedly mounted on a base; a tank 402 placed inside the placement seat 401, the tank 402 containing coating, which can be replaced with another tank 402 or replenished with coating after the coating is used up; a conveying pipe 403 fixedly mounted between the additive 4 and the tank 402, the conveying pipe 403 connecting the additive 4 and the tank 402, the connection between the conveying pipe 403 and the tank 402 being detachable; and a moving component B mounted on a frame 1, the moving component B being connected to the additive 4 to control the reciprocating back-and-forth movement of the additive 4, changing the position of the coating added by the additive 4 to the silicon steel strip.

[0036] See Figures 5-6 The moving component B includes: a functional roller 404 rotatably mounted on the frame 1, the functional roller 404 being used to guide the silicon steel belt to pass under the additive 4, the functional roller 404 being able to be rotated by the moving silicon steel belt, the functional roller 404 having a spiral groove that is connected end to end; and a connecting rod 405 installed between the functional roller 404 and the additive 4, one end of the connecting rod 405 being slidably connected to the groove of the functional roller 404, and the other end being fixedly connected to the additive 4.

[0037] During the process of transporting the silicon steel belt for coating, the functional roller 404 is driven to rotate by the moving silicon steel belt, which in turn controls the connecting rod 405 to move back and forth, thereby controlling the additive 4 to move back and forth, so that the additive 4 can evenly add coating on the silicon steel belt, so that the coating can be evenly spread later.

[0038] See Figures 7-8 The leveling mechanism includes: a rotatable extrusion roller 5 mounted on the frame 1, two extrusion rollers 5 are provided, and the two extrusion rollers 5 are close to each other. When the silicon steel strip passes between the two extrusion rollers 5, the coating on the silicon steel strip will be evenly leveled by the extrusion rollers 5; a movable component C mounted on the frame 1, the movable component C is connected to one of the extrusion rollers 5 to control the movement of the extrusion roller 5, so as to facilitate the passing of the silicon steel strip between the two extrusion rollers 5.

[0039] See Figures 7-8 The moving component C includes: a groove rail 501 fixedly mounted on the frame 1, wherein one of the extrusion rollers 5 is slidably connected to the groove rail 501; a gear B502 rotatably mounted on the frame 1; a rack 503 slidably mounted on the frame 1, the rack 503 meshing with the gear B502, and the rack 503 rotatably connected to the extrusion roller 5 which can move freely; and a motor B504 fixedly mounted inside the frame 1, the output end of the motor B504 being fixed to the gear B502.

[0040] The motor B504 is started, and the extrusion roller 5 is controlled to move up and down through the transmission of gear B502 and rack 503, thereby changing the distance between the two extrusion rollers 5, which facilitates the loading of silicon steel strip. When the silicon steel strip is transported to the extrusion roller 5 after the coating is added, the extrusion roller 5 is rotated by the silicon steel strip, and the coating is evenly spread on various positions on the silicon steel strip, thus completing the coating work.

[0041] In summary, coating is one step in the silicon steel strip processing flow. The silicon steel strip insulation coating machine can be installed among the devices involved in the silicon steel strip processing flow. Therefore, the specific operating steps of the silicon steel strip insulation coating machine are as follows:

[0042] S1. First, the silicon steel strip, which has been transported to the silicon steel strip insulation coating machine after the previous processing, is passed through two cleaning rollers 3 and around two guide rollers 2 in sequence. Second, the motor B504 is started to control the extrusion rollers 5 to separate and pass the silicon steel strip between the extrusion rollers 5. Then, the motor B504 is reversed to control the two extrusion rollers 5 to come closer. Finally, the silicon steel strip is connected to the processing device involved in the next processing step, thus completing the loading of the silicon steel strip into the silicon steel strip insulation coating machine.

[0043] S2. Start motor A308 to control the cleaning roller 3 to rotate and move in a staggered manner. The cleaning roller 3 removes impurities attached to the silicon steel strip passing through it.

[0044] S3. Start the additive 4 to add paint onto the silicon steel belt. The functional roller 404 is rotated by the moving silicon steel belt, while the control additive 4 moves back and forth. The extrusion roller 5 flattens the paint coated on the silicon steel belt that passes through it.

[0045] S4. Finally, after completing the coating process of the silicon steel strip, turn off motor A308.

[0046] The above embodiments are merely specific implementations of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
