[0002] Metal coils refer to continuously rolled metal materials, usually divided into sheet coils and wire coils. This material has a wide range of applications in industrial production, mainly used to manufacture various metal products and components. However, metal coils may rust during long-term storage, thus requiring the use of rust removal equipment to polish the rusted metal coils.

[0003] Currently, when using rust removal equipment to grind the unfolded coiled material with grinding rollers, some rust adheres to the surface of the grinding rollers. However, the equipment usually cannot clean the grinding rollers during use. Rust accumulation leads to an uneven surface on the grinding rollers, reducing the actual effective grinding area in contact with the coiled material. This reduces the effectiveness of the rust removal equipment. Utility Model Content

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.

[0021] Please see Figure 1-4As shown, a metal coil rust removal device includes a main body 1, which can transport the unfolded metal coil under the action of the main body 1. A U-shaped frame 2 is bolted to both sides of the surface of the main body 1. A protective cover 3 is provided above the main body 1, and the protective cover 3 can be inserted into the interior of the U-shaped frames 2. The two sides of the protective cover 3 are convex, and the thickness of the convex surface of the protective cover 3 is greater than the wall thickness of the U-shaped frame 2. Under this action, the protective cover 3 can be initially positioned. An L-shaped plate 4 is bolted to the side of the U-shaped frame 2 away from the surface of the main body 1, and a positioning mechanism is provided on the surface of the L-shaped plate 4. Structure 5, under the action of L-shaped plate 4, can prevent the parts inside the positioning mechanism 5 from easily falling off. When the parts inside the positioning mechanism 5 enter the inner cavity of the protective cover 3, it can prevent the protective cover 3 from easily moving. Under the action of the electrical control box in the main body 1 of the rust removal device, it can drive the grinding roller to rotate. When the grinding roller rotates, it can grind the metal coil that passes through the grinding roller. Under this action, the rust on the surface of the metal coil can be removed. Under the action of the protective cover 3, it can prevent the impurities generated during grinding from splashing onto the surrounding personnel. A lead screw 6 is fixedly connected to the side of L-shaped plate 4 away from the surface of the main body 1 of the rust removal device. The surface of the lead screw 6 is threaded. A baffle 7 is provided, which can limit the movement of parts inside the positioning mechanism 5 when it rotates to a suitable position. A collection box 8 is bolted to the top of the protective cover 3. A suction fan 9 is connected to the right side surface of the collection box 8, and a pipe rack 10 is connected to the left side surface of the collection box 8. A collection shell 11 is connected to the air inlet of the pipe rack 10. The number of collection shells 11 is equal to the number of grinding rollers in the main body 1 of the rust removal device, and the air inlet of the collection shell 11 is close to the surface of the grinding rollers of the main body 1 of the rust removal device. Under the action of the suction fan 9, the collection shell 11 can generate suction, which can clean the main body of the rust removal device. Rust adhering to the surface of the grinding roller enters the interior of the collection shell 11. Rust inside the collection shell 11 can enter the interior of the pipe rack 10. Rust inside the pipe rack 10 can enter the interior of the collection box 8. A filter screen plate 12 is slidably connected to one side of the inner wall of the collection box 8. Under the action of the filter screen plate 12, the rust inside the collection box 8 can be prevented from being easily discharged. A vibration mechanism 13 is provided inside the collection box 8. When the suction fan 9 runs, the vibration mechanism 13 can be activated. When the vibration mechanism 13 runs, it can drive the filter screen plate 12 to vibrate. Under this action, the rust can be prevented from easily clogging the filter screen plate 12.

[0022] The positioning mechanism 5 includes a first tension spring 51. One end of the first tension spring 51, away from the surface of the rust removal device body 1, is fixedly connected to one side of the surface of the L-shaped plate 4. The other end of the first tension spring 51 is fixedly connected to a positioning plate 52. Connecting rods 53 are fixedly connected to both sides of the other side of the positioning plate 52. One end of the connecting rod 53 passes through the surface of the L-shaped plate 4 and is slidably connected to it at the point of penetration. Pull plates 54 are bolted to the other ends of the connecting rods 53. When the pull plates 54 move away from the rust removal device body 1, the connecting rods 53 can move. When the connecting rods 53 move, the positioning plate 52 can move. When the positioning plate 52 moves, the positioning plate 52 can move. The first tension spring 51 is compressed. When the positioning plate 52 moves to the appropriate position, it can release the obstruction at the bottom of the loop frame 2. Under this action, the protective cover 3 can be prevented from passing through the inner cavity of the loop frame 2. When the pull plate 54 moves to the appropriate position, the baffle 7 is rotated. When the baffle 7 rotates to the appropriate position, it can contact the side of the pull plate 54 that is close to the surface of the rust removal device body 1. Under this action, the pull plate 54 can be prevented from easily rebounding. After the protective cover 3 is placed, the contact between the baffle 7 and the pull plate 54 is released. Under the action of the first tension spring 51, the positioning plate 52 can be returned to its original position. Under this action, the positioning plate 52 can enter the inner cavity of the protective cover 3 to prevent the protective cover 3 from easily moving.

[0023] The vibration mechanism 13 includes a bevel gear set 131, which consists of two bevel gears. The right bevel gear of the bevel gear set 131 is fixedly connected to the left end of the output shaft of the suction fan 9. When the suction fan 9 is running, the bevel gear set 131 can rotate. A transmission rod 132 is fixedly connected to the inner wall of the left bevel gear of the bevel gear set 131. The two ends of the surface of the transmission rod 132 are rotatably connected to the inner wall of the collection box 8. When the bevel gear set 131 rotates, the transmission rod 132 can rotate. Cams 133 are fixedly connected to both sides of the surface of the transmission rod 132. When the transmission rod 132 rotates, the two cams 133 on both sides can rotate. When the filter screen 12 is moved to the appropriate position, it can move to the left. A second tension spring 134 is fixedly connected to the right side surface of the filter screen 12. There are four second tension springs 134, which are evenly distributed at the four corners of the right side surface of the filter screen 12. The other end of the surface of the second tension spring 134 is fixedly connected to the right side of the inner wall of the collection box 8. When the filter screen 12 moves to the left, the second tension spring 134 can be stretched. When the cams 133 on both sides continue to rotate and release the contact with the surface of the filter screen 12, the filter screen 12 can rebound under the action of the second tension spring 134. This process is repeated, and under this action, the filter screen 12 can be in a state of vibration.

[0024] Working principle: When it is necessary to remove rust from the unfolded metal coil, pull the pull plates 54 on both sides. When the pull plates 54 move, the connecting rods 53 on both sides can move. Then, the moving connecting rods 53 on both sides can move the positioning plate 52. Next, the moving positioning plate 52 can compress the first tension spring 51. When the positioning plate 52 moves to the appropriate position, it can release the obstruction at the bottom of the return frame 2. Then, rotate the baffle 7. When the baffle 7 rotates to the appropriate position, it can contact the surface of the pull plate 54 near the rust removal device body 1. Under this action, the pull plate 54 can be prevented from moving. The protective cover 3 is easily returned to its original position. Next, the protective cover 3 is inserted into the inner cavity of the two side retaining frames 2. Then, the baffle 7 is rotated to release the limiting position of the pull plate 54. Similarly, under the action of the first tension spring 51, the positioning plate 52 can drive the pull plate 54 back to its original position. When the positioning plate 52 returns to its original position, it can enter the inner cavity of the protective cover 3. Under this action, the protective cover 3 can be positioned. Under the action of the protective cover 3, rust can be prevented from splashing onto surrounding personnel when the grinding roller of the main body 1 of the rust removal device grinds the unfolded metal coil. At the same time, the suction fan 9 is turned on when the grinding roller is grinding. Under the action of the suction fan 9, the rust adhering to the surface of the grinding roller can enter the interior of the collection shell 11. Then, the rust inside the collection shell 11 can enter the interior of the pipe rack 10. Next, the rust inside the pipe rack 10 can enter the interior of the collection box 8. Under the action of the filter screen 12, the rust inside the collection box 8 can be prevented from being easily discharged. Then, when there is too much rust inside the collection box 8, the collection box 8 can be opened to clean the rust. At the same time, when the suction fan 9 is running, it can rotate the bevel gear set 131. Then, the rotation of the bevel gear set 131 can drive the transmission rod 13. 2. Rotation of the transmission rod 132 causes the cams 133 on both sides to rotate. When the cams 133 on both sides rotate to the appropriate position, the filter screen 12 can be moved. Then, the movement of the filter screen 12 can stretch the second tension spring 134. Then, the cams 133 on both sides continue to rotate to release the contact with the filter screen 12. Next, under the action of the second tension spring 134, the filter screen 12 can return to its original position. This process is repeated, and under this action, the filter screen 12 can be in a vibrating state, which can prevent rust from easily clogging the filter screen 12.
