[0002] A cold strip rolling mill is a device used to roll steel strip at room temperature. It mainly consists of a working mechanism and a transmission mechanism. The working mechanism includes a frame and rolls, while the transmission mechanism includes a gear base and a reducer. The steel strip is pulled by an electric motor, and pressure is applied by the rolls. By changing the roll gap, the thickness of the steel strip is reduced, producing products of different specifications. It offers advantages such as precise product dimensions, superior surface quality, and the ability to produce extremely thin strips.
[0003] Publication No. (CN220739025U) discloses a cold rolling mill for steel strip, including a mill body and a straightening device disposed on the feed side of the mill body. The straightening device includes a mounting frame, a straightening wheel assembly, and a guide assembly disposed on the mounting frame. The straightening wheel assembly includes an upper roll group and a lower roll group, forming a straightening space between them. The guide assembly includes a first guide member and a second guide member respectively disposed on both sides of the straightening space, the first guide member and the second guide member being able to move closer to or further away from the center of the straightening space. By providing a straightening device on the feed side of the cold rolling mill body, the steel strip is straightened before entering the rolling rolls of the cold rolling mill. Simultaneously, the first and second guide members, which are able to move closer to or further away from the center of the straightening space, guide the steel strip, preventing the center of the steel strip from deviating from the rolling centerline and ensuring the rolling quality of the steel strip.
[0004] However, this type of cold rolling mill for steel strip has the following drawbacks: it cannot clean impurities on the surface of the steel strip while fulfilling the guiding function, thus preventing jamming during the production process. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a novel guide device for cold rolling mill of steel strip, so as to solve the problem that the prior art cannot clean the impurities on the surface of the steel strip while satisfying the guiding function.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel guide device for a cold rolling mill of steel strip, comprising...
[0007] A protective plate has a movable frame slidably connected to its inner wall, a sliding sleeve fixedly connected to the inner wall of the movable frame, a sliding plate slidably connected to the inner wall of the sliding sleeve, a top block fixedly connected to the outside of the sliding plate, multiple springs fixedly connected to the end of the sliding plate away from the top block, support frames fixedly connected to both ends of the top block, a brush wheel rotatably connected to the adjacent end of the support frame, and a drive assembly for driving subsequent components fixedly connected to the outside of the protective plate.
[0008] The drive assembly includes a hydraulic cylinder, which is fixedly connected to the outside of the protective plate.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0023] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a novel guide device for a cold rolling mill of steel strip, including...
[0024] A protective plate 1 has a sliding frame 2 slidably connected to its inner wall. The protective plate 1 protects the internal structure and provides a guiding and supporting inner wall surface for the sliding of the moving frame 2, allowing it to slide stably on its inner wall and thus enabling some of the movement functions of the entire device. A sliding sleeve 3 is fixedly connected to the inner wall of the moving frame 2. As an important movable component in the entire device, the sliding sleeve 3 provides a track for the moving frame 2 to slide along a certain direction within its inner wall, providing a basis for further movement of the entire device. A sliding plate 4 is slidably connected to the inner wall of the sliding sleeve 3. The sliding plate 4 inside the sliding sleeve 3 can slide flexibly within its inner wall. This sliding characteristic of the sliding plate 4 is one of the key aspects of the entire device in achieving the cleaning of impurities on the surface of the steel strip and adapting to changes in the position of the steel strip. A top block 5 is fixedly connected to the outside of the sliding plate 4. The top block 5 is tightly connected to the sliding plate 4 and plays a role in transmitting force and adjusting position in the device. When the sliding plate 4 is subjected to pressure or external force, the top block 5 will move along with the sliding plate 4.
[0025] Multiple springs 6 are fixedly connected to the end of the slide plate 4 furthest from the top block 5. These springs 6, with their elastic deformation properties, compress or stretch when the slide plate 4 is subjected to external force, thus providing cushioning and a certain restoring force. This allows the slide plate 4 to better adapt to different situations during movement and meet the operational requirements of the device. Support frames 7 are fixedly connected to both ends of the top block 5. These support frames 7 primarily support and fix the brush wheels 8, ensuring their stable installation within the device. Through the connection between the top block 5 and the slide plate 4, the support frames 7 move with the slide plate 4, thereby driving the brush wheels 8 to perform corresponding actions. The brush wheels 8 are rotatably connected to the adjacent ends of the support frames 7. A brush wheel 8 is rotatably connected to one end of the support frame 7. A brush is connected to the brush wheel 8. When the steel belt comes into contact with the brush wheel 8 through the movable frame 2, the brush wheel 8 will rotate due to the movement of the steel belt. At this time, the brush on the brush wheel 8 can clean the impurities on the outside of the steel belt and play the role of cleaning the surface of the steel belt.
[0026] The drive assembly includes a hydraulic cylinder 9, which is externally fixed to the outside of the protective plate 1. The hydraulic cylinder 9, fixed to the outside of the protective plate 1, serves as a power source, generating thrust through hydraulic pressure to provide power for the entire device to perform corresponding actions. It is a crucial component for the device's automation. A push block 10 is fixedly connected to the drive end of the hydraulic cylinder 9. When the hydraulic cylinder 9 operates, its drive end extends or retracts, causing the push block 10 to move. The movement of the push block 10 further drives the connected movable frame 2 to move, thus achieving motion control of the device. Two slide rods 11 are fixedly connected to the outside of the protective plate 1. These two slide rods 11 guide the movement of the push block 10, ensuring stable movement along the direction of the slide rods 11 during movement, guaranteeing the accuracy and stability of the device's motion. Rollers 12 are rotatably connected to the outside of the movable frame 2.
[0027] The movable frame 2 is externally connected to rollers 12. During the movement of the movable frame 2, the rollers 12 reduce the friction between the movable frame 2 and the protective plate 1 or other components, making the movement of the movable frame 2 smoother. They also provide support and stability to a certain extent. Multiple positioning wheels 13 are fixedly connected to the inner wall of the rollers 12. The steel belt moves within the guide grooves of the positioning wheels 13, which position and guide the steel belt, ensuring it moves along a predetermined path. Furthermore, if the steel belt deviates, the movement of the movable frame 2 can correct and adjust the steel belt through the positioning wheels 13. The inner wall of the protective plate 1 has a movable groove 14. This groove provides space for the sliding of the movable frame 2, allowing it to move up and down or in other directions within the groove, meeting the device's needs for adjusting and cleaning the steel belt position.
[0028] The external sliding connection of the movable frame 2 is to the inner wall of the movable groove 14. This slidable connection allows the movable frame 2 to slide stably within the groove 14, ensuring its trajectory within the device and enabling it to move in a predetermined manner to guide and clean the steel strip. The external sliding connection of the slide rod 11 is to the inner wall of the push block 10. This slidable connection allows the push block 10 to move along the direction of the slide rod 11. The slide rod 11 provides accurate guidance for the movement of the push block 10, ensuring its stability and accuracy during movement, thus guaranteeing the normal operation of the entire device.
[0029] The top block 5 is slidably connected to the inner wall of the sliding sleeve 3. This slidable connection allows the top block 5 to slide within the sliding sleeve 3. When the moving frame 2 moves up and down, the top block 5 slides within the sliding sleeve 3, which in turn drives the brush wheel 8 to perform corresponding actions via the support frame 7, adapting to changes in the steel belt's position. The end of the spring 6 furthest from the slide plate 4 is fixedly connected to the inner wall of the sliding sleeve 3. When the slide plate 4 is subjected to pressure transmitted by the top block 5, the spring 6 is compressed. The elastic restoring force of the spring 6 ensures that the slide plate 4 returns to its original position after the pressure is removed. Simultaneously, it acts as a buffer and adjuster during the movement of the slide plate 4, allowing the brush wheel 8 to better adhere to the surface of the steel belt for cleaning.
[0030] The outer surface of the push block 10 contacts the outer surface of the protective plate 1. This contact ensures the stability of the push block 10 during movement, and under the drive of the hydraulic cylinder 9, the push block 10 accurately transmits power to the moving frame 2, ensuring the normal operation and accuracy of the device. The outer surface of the brush wheel 8 contacts the outer surface of the top block 5. The top block 5 supports the brush wheel 8 via the support frame 7. When the moving frame 2 moves, the top block 5 drives the brush wheel 8 to move accordingly. Simultaneously, the contact between the brush wheel 8 and the top block 5 ensures the stability and effectiveness of the brush wheel 8 in cleaning impurities from the steel strip surface.
[0031] The outer surface of the top block 5 contacts the inner wall of the movable frame 2. This contact allows the top block 5 to move with the movable frame 2. When the movable frame 2 moves up and down or in other directions, the top block 5 transmits this movement to the connected support frame 7 and brush wheel 8, thereby cleaning impurities on the steel strip surface and adjusting the position of the steel strip. The outer surface of the support frame 7 also contacts the inner wall of the movable frame 2. This contact allows the support frame 7 to be stably installed inside the movable frame 2, and when the movable frame 2 moves, the support frame 7 moves with it, thereby driving the brush wheel 8 to perform corresponding actions, ensuring the stability and effectiveness of the brush wheel 8 in cleaning impurities on the steel strip surface.
[0032] The outer surface of the brush wheel 8 is in contact with the outer surface of the protective plate 1. During operation, when the moving frame 2 moves to a certain position, the contact between the brush wheel 8 and the protective plate 1 provides a limiting effect, while also ensuring the stability and accuracy of the brush wheel 8 in cleaning impurities from the steel strip surface. This contact allows the brush wheel 8 to move with the moving frame 2. When the moving frame 2 moves, the brush wheel 8 will rotate or move accordingly due to its contact with the moving frame 2, thereby cleaning impurities from the steel strip surface and adjusting the position of the steel strip, ensuring the normal operation and effectiveness of the device.
[0033] The working process of this utility model is as follows:
[0034] First, when the steel belt contacts the brush wheel 8 through the moving frame 2, the brush wheel 8 will generate transmission due to the movement of the steel belt. The brush wheel 8 is connected to a brush, so when the brush wheel 8 rotates, it will clean the impurities on the outside of the steel belt. The movement of the moving frame 2 will generate up and down movement. At this time, the support frame 7 connected to the brush wheel 8 will apply pressure to the spring 6 under the slide plate 4 through the top block 5. After being pressured, the slide plate 4 will retract, which ensures that the brush wheel 8 is in close contact with the steel belt while having enough room to move. This achieves the cleaning of stubborn impurities on the surface of the steel belt, avoids the situation of the steel belt getting stuck due to impurities, and improves production efficiency.
[0035] By activating the hydraulic cylinder 9, the hydraulic cylinder 9 drives the moving frame 2 to move via the push block 10. The moving frame 2 is internally connected to a positioning wheel 13, and the steel belt moves in the guide groove inside the positioning wheel 13. When the steel belt deviates, the movement of the moving frame 2 can correct and adjust the steel belt, thereby improving work efficiency and saving production materials.
