Description

Technical Field

[0001] This utility model relates to the field of steel coil production technology, and in particular to a steel coil slitting and flattening device. Background Technology

[0002] The steel coil slitting and flattening device is a combined piece of equipment used for finishing hot-rolled steel coils. It integrates multiple functions such as leveling (straightening), slitting (rewinding), and flattening, aiming to improve the geometry, mechanical properties, and surface quality of finished strip steel, and to slit large coils into smaller coils as required. During transportation and storage, steel coils are prone to the adhesion of impurities such as oxide scale and dust. If impurities in existing equipment are pressed into the steel plate surface during the flattening process, they will form defects such as indentations and scratches. More seriously, the particles swept off can diffuse around the equipment, potentially causing secondary contamination of the steel coils and affecting the cleanliness of the final product. Furthermore, traditional flattening mechanisms mostly use rigid pressure rollers and fixed pressure modes, which are difficult to flexibly adapt to steel coils of different thicknesses or those with slight waviness, camber, or other plate shape defects. Insufficient pressure will lead to incomplete leveling, leaving the steel coil uneven; excessive pressure can easily create new indentations or warping on the surface, and even cause edge damage to thin-gauge steel coils. Therefore, we propose a steel coil slitting and flattening device. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a steel coil slitting and flattening device to solve the issues raised in the background art.

[0004] This utility model discloses a steel coil slitting and flattening device, comprising a base plate. The base plate has a support at its upper end, a first cylinder at its upper end, an output frame at the first cylinder, a motor on one side of the mounting frame, a cleaning roller at the motor's output end, a collection box at the top of the support, a negative pressure fan and a filter plate inside the collection box, and a dust collection hood connected to the other side of the collection box via a pipe. The base plate also has a second cylinder at its upper end, an electric slide rail at its output end, a slider movably mounted on the upper end of the electric slide rail, a connecting rod at the lower end of the slider, a support plate at the lower end of the connecting rod, a sliding rod movably mounted on the support plate, a spring sleeved on the sliding rod, a connecting frame at the lower end of the sliding rod, and a pressure roller movably mounted within the connecting frame.

[0005] In the above scheme, the cleaning roller is movably mounted in the mounting frame via bearings, and the pressure roller is movably mounted in the connecting frame via bearings.

[0006] In the above scheme, a fixed frame is provided at the top of the bracket, and a dust collection hood is installed on the fixed frame.

[0007] In the above scheme, the air inlet end of the dust collection hood faces the cleaning roller.

[0008] In the above scheme, pressure rollers are symmetrically arranged on the left and right sides of the support plate.

[0009] In the above scheme, a limiting plate is fixedly provided at the top of the connecting rod.

[0010] In the above scheme, the lower end of the limiting plate is connected to a spring, and the other end of the spring is connected to a support plate.

[0011] The advantages and beneficial effects of this utility model are as follows: It can actively remove dust particles from the surface of steel coils, preventing impurities from causing surface depressions during flattening and ensuring a good flattening effect from the source. At the same time, the matching negative pressure fan, dust collection hood, and collection box can promptly suck up the dust generated during the cleaning process and filter it through the filter plate, effectively preventing secondary pollution during the cleaning process. This not only optimizes the final cleanliness of the steel coils but also improves the working environment around the equipment.

[0012] The flattening core mechanism employs a flexible pressure system composed of slide bars, springs, and limiting plates. When the pressure roller contacts the surface of the steel coil, the spring provides continuous and flexible pressure, allowing the pressure roller to adaptively conform to the minute undulations of the steel coil surface, thereby achieving more uniform flattening. This flexible contact method avoids indentations or scratches that may be caused by rigid pressure rollers, effectively protecting the surface quality of the steel coil while ensuring the flattening effect.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-4 As shown, this utility model is a steel coil slitting and flattening device, including a base plate 1. The base plate 1 has a support 11 at its upper end, and a first cylinder 12 at its upper end. The output end of the first cylinder 12 has a mounting frame 13. A motor 14 is located on one side of the mounting frame 13, and a cleaning roller 15 is located at the output end of the motor 14. The steel coil to be flattened passes through the upper end of the base plate 1, and a winding device is located at the other end. When the steel coil passes through the upper end of the base plate 1, the first cylinder 12 is turned on, and its output end pushes the mounting frame 13 to begin winding. As the mounting frame 13 moves downward, the cleaning roller 15 at the lower end begins to move downward, bringing the cleaning brush of the cleaning roller 15 into contact with the upper surface of the steel coil. The motor 14 is then turned on again. The cleaning roller 15 is movably mounted inside the mounting frame 13 via bearings. The output end of the motor 14 drives the cleaning roller 15 to rotate within the mounting frame 13. Simultaneously, the cleaning brush cleans the upper surface of the steel coil, removing dust particles adhering to the surface. This prevents the presence of dust particles from causing dents on the surface of the steel coil during the flattening process, thus affecting the flattening effect.

[0021] The top of the support 11 is equipped with a collection box 2. Inside the collection box 2 are a negative pressure fan 21 and a filter plate 22. The other side of the collection box 2 is connected to a dust collection hood 25 through a pipe 23. When the cleaning roller 15 starts cleaning the steel coil, the negative pressure fan 21 is turned on, and the negative pressure fan 21 starts to generate suction in the collection box 2. Through the pipe 23, suction is generated at the end of the dust collection hood 25, which allows the dust generated by the cleaning roller 15 to be adsorbed in the dust collection hood 25. After being filtered by the filter plate 22, the dust particles are concentrated and collected in the collection box 2, which can avoid the dust from causing secondary pollution of the steel coil during the cleaning operation of the cleaning roller 15, thus affecting the cleaning effect of the steel coil.

[0022] The base plate 1 has a second cylinder 3 on its upper end, and an electric slide rail 31 at the output end of the second cylinder 3. A slider 32 is movably mounted on the upper end of the electric slide rail 31, and a connecting rod 33 is mounted on the lower end of the slider 32. A support plate 34 is mounted on the lower end of the connecting rod 33, and a sliding rod 4 is movably mounted on the support plate 34. A spring 41 is sleeved on the outside of the sliding rod 4, and a connecting frame 43 is mounted on the lower end of the sliding rod 4. A pressure roller 44 is movably mounted inside the connecting frame 43. The cleaned steel coil enters the lower end of the pressure roller 44. By turning on the switch of the second cylinder 3, the telescopic end of the second cylinder 3 moves the upper electric slide rail 31 downwards, moving the pressure roller 44 to the upper surface of the steel coil. By turning on the switch of the electric slide rail 31, the slider 32 at the upper end of the electric slide rail 31 begins to move left and right, and the pressure roller 44 moves to the upper surface of the steel coil. Roller 44 is movably mounted within connecting frame 43 via bearings. Roller 44 can rotate within connecting frame 43, ensuring smooth flattening operation. The two lower rollers 44 begin flattening the upper surface of the steel coil. After roller 44 contacts the upper surface of the steel coil, slide rod 4 at the upper end of connecting frame 43 begins to move upwards. A limiting plate 42 is fixedly mounted on the top of connecting rod 33. A spring 41 is connected to the lower end of the limiting plate 42, and the other end of the spring 41 is connected to support plate 34. Slide rod 4 pushes the limiting plate 42 to stretch the spring 41. The spring 41 provides continuous, flexible pressure, allowing roller 44 to closely conform to the minute undulations of the steel coil surface, achieving a more uniform flattening effect. Flexible contact prevents the rigid roller 44 from causing indentations, scratches, or other damage to the steel coil surface.

[0023] In the above scheme, a fixed frame 24 is provided at the top of the bracket 11, and a dust collection hood 25 is installed on the fixed frame 24. The air inlet end of the dust collection hood 25 faces the cleaning roller 15, and the dust collection angle of the dust collection hood 25 is fixed at the lower end of the bracket 11 to ensure that dust particles are fully adsorbed by the dust collection hood 25.

[0024] In the above scheme, pressure rollers 44 are symmetrically provided on the left and right sides of the support plate 34, and the pressure rollers 44 at both locations can ensure that the steel coil is fully flattened.

[0025] Working principle: In operation, this type of steel coil slitting and flattening device involves passing the steel coil to be flattened through the top of the base plate 1, with a winding device at the other end. As the steel coil passes through the top of the base plate 1, the first cylinder 12 is activated, causing its output to push the mounting frame 13 downwards. Simultaneously, the motor 14 is activated, and the cleaning brush cleans the upper surface of the steel coil. Furthermore, the negative pressure fan 21 is activated, generating suction within the collection box 2, which draws dust through the pipe 23. The suction force generated at the end of the cover 25 concentrates the dust particles into the collection box 2. The cleaned steel coil enters the lower end of the pressure roller 44. By turning on the switch of the second cylinder 3, the extension end of the second cylinder 3 moves the upper electric slide rail 31 downward, moving the pressure roller 44 to the upper surface of the steel coil. The two pressure rollers 44 at the lower end begin to flatten the upper surface of the steel coil. The spring 41 can provide continuous and flexible pressure, so that the pressure roller 44 can closely fit the slight undulations of the steel coil surface, achieving a more uniform flattening effect.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
