Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of aluminum strip production equipment, and particularly relates to a roller cleaning device for an aluminum strip rolling mill. Background Art
[0002] Calendering is a common processing method in the metalworking industry. After passing through the calendering mill, aluminum strip thins and lengthens. During the calendering process, high-strength materials generate significant heat. Furthermore, cold rolling is affected by the raw materials, resulting in a high amount of aluminum ash adhering to the surface. This can lead to the formation of putty strips on the surface of some materials, particularly the lower surface, after rolling. These strips are difficult to remove through subsequent processing. These putty strips are irregular, whitish or grayish lines that appear along the rolling direction of the mill, forming strips or bands on the lower surface of the strip.
[0003] During the rolling process of aluminum strip, oil is required for cooling and lubrication. Oil-coated rollers are prone to attracting aluminum ash, airborne dust, and particulate matter from the aluminum strip's surface. This accumulation accumulates over time, severely impacting the strip's processing quality. The resulting aluminum strip is relatively flat and prone to forming putty streaks.
[0004] At present, most rolls are cleaned by blowing nozzles, which are relatively fixed in position and can only clean a local area of a single roll. Even if multiple blowing nozzles and their accessories are installed on the side of each roll, it is difficult to completely remove the aluminum ash and dust on the roll surface, and the cost is greatly increased. Utility Model Content
[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides an aluminum strip rolling mill roll cleaning device, which aims to solve the problems that the existing roll blowing nozzle is relatively fixed in position, has poor applicability, and has poor blowing effect, which seriously affects the processing quality of aluminum strips.
[0006] To achieve the above purpose, the utility model is arranged as follows:
[0007] A roller cleaning device for an aluminum strip rolling mill comprises a pneumatic slide arranged at the top of the aluminum strip rolling mill, the pneumatic slide and the rollers on the aluminum strip rolling mill are perpendicular to each other, an electric telescopic rod is provided on the lower side of the slider of the pneumatic slide, the telescopic end of the electric telescopic rod is fixedly connected to a U-shaped frame, a cylindrical groove is provided in the U-shaped frame, a power supply and a motor are installed in the cylindrical groove, the output end of the motor is fixedly connected to a rotating shaft rotatably connected to the cylindrical groove, the rotating shaft and the cylindrical groove are parallel to the rollers, a plurality of scrapers with uniform spacing are provided on the circumferential side of the rotating shaft, and the cleaning device is also equipped with a controller, and the pneumatic slide, the electric telescopic rod and the motor are all electrically connected to the controller.
[0008] Furthermore, both ends of the columnar groove are provided with cross bars rotatably connected to the U-shaped frame, and a movable cavity is provided in the vertical section of the U-shaped frame corresponding to one of the cross bars, and a gear fixedly connected to the cross bar is provided in the movable cavity, and a rack slidably connected to the U-shaped frame is provided on one side of the gear, and the rack is meshed with the gear, and one end of the rack is rotatably connected to an adjusting bolt extending out of the U-shaped frame, and the adjusting bolt is threadedly connected to the U-shaped frame.
[0009] This structural design allows the cylindrical slot to be rotated by adjusting the bolts, thereby adjusting the direction of the notch in the cylindrical slot, allowing cleaning of rollers at different locations within the aluminum strip mill. For example, when the rollers are at their left or right extreme positions within the mill, the cylindrical slot, which cannot be rotated and adjusted, can only clean the rollers on one side, which is a limitation.
[0010] Furthermore, an elastic plastic scraper is provided at one end of the scraper away from the rotating shaft.
[0011] With this structural design, the elastic plastic scraper cooperates with the scraper, so that the elastic plastic scraper can fully contact the roller, resulting in a good cleaning effect without scratching the roller.
[0012] Furthermore, an airway chamber is provided inside the arcuate side of the columnar groove, and fine air outlet holes are opened at the notches on the arcuate side of the columnar groove, and the air outlet holes are communicated with the airway chamber. An air pipe connected to the airway chamber is provided on the outside of the columnar groove, and the air pipe is equipped with an air pump.
[0013] This structural design allows air to be blown out through the air holes, thereby further processing the rollers cleaned by the elastic plastic scrapers and scrapers to remove attached fine particles.
[0014] Furthermore, the air pipe is a corrugated hose.
[0015] This structural design facilitates the stretching and bending of the trachea.
[0016] Beneficial effects:
[0017] 1. The roller cleaning device of the utility model is equipped with a pneumatic slide, an electric telescopic rod, a U-shaped frame, a columnar trough, a motor, a rotating shaft, a scraper and a controller. The relative position of the columnar trough can be flexibly adjusted according to the situation, so that the scraper can clean the rollers at different positions and heights. After cleaning, the rollers are blown through the air outlet holes on the columnar trough to ensure thorough cleaning, thereby ensuring the flatness of the aluminum strip and avoiding the formation of putty strips.
[0018] 2. The roller cleaning device of the present invention is also provided with a cross bar, a gear, a rack, and an adjusting bolt. The cylindrical groove can be rotated by adjusting the bolt to adjust the direction of the notch of the cylindrical groove so as to clean the rollers at different positions in the aluminum strip rolling mill.

[0025] like Figures 1 to 3As shown, the present invention discloses a roller cleaning device for an aluminum strip mill, comprising a pneumatic slide 1 disposed at the top of the aluminum strip mill. The pneumatic slide 1 and the rollers of the aluminum strip mill are perpendicular to each other. An electric telescopic rod 3 is mounted on the underside of the slider 2 of the pneumatic slide 1, and the telescopic end of the electric telescopic rod 3 is fixedly connected to a U-shaped frame 4. The U-shaped frame 4 is provided with a cylindrical groove 5, and a power supply and a motor 6 are mounted in the cylindrical groove 5. The output end of the motor 6 is fixedly connected to a rotating shaft 7 that is rotatably connected to the cylindrical groove 5. The rotating shaft 7 and the cylindrical groove 5 are both parallel to the rollers. A plurality of evenly spaced scrapers 8 are provided on the circumference of the rotating shaft 7. The cleaning device of the present invention is also equipped with a controller, and the pneumatic slide 1, the electric telescopic rod 3, and the motor 6 are all electrically connected to the controller.
[0026] As a preferred embodiment of this embodiment, both ends of the columnar groove 5 are fixedly connected to cross bars 9 rotatably connected to the U-shaped frame 4, and a movable cavity is provided in the vertical section of the U-shaped frame 4 corresponding to one of the cross bars 9, and a gear 10 fixedly connected to the cross bar 9 is provided in the movable cavity. A rack 11 slidingly connected to the U-shaped frame 4 is provided on the left side of the gear 10, and the rack 11 is engaged with the gear 10. The upper end of the rack 11 is rotatably connected to the adjusting bolt 12 extending out of the U-shaped frame 4, and the adjusting bolt 12 is threadedly connected to the U-shaped frame 4.
[0027] As a preference of this embodiment, one end of the scraper 8 away from the rotating shaft 7 is fixedly connected to an elastic plastic scraper blade.
[0028] As a preferred embodiment of this embodiment, an airway chamber is provided inside the arcuate side of the columnar groove 5, and fine air outlet holes are opened at the notches on the arcuate side of the columnar groove 5, and the air outlet holes are communicated with the airway chamber. An air pipe connected to the airway chamber is provided on the outside of the columnar groove 5, and the air pipe is equipped with an air pump.
[0029] As a preference of this embodiment, the air pipe is a corrugated hose.
[0030] When the rollers need to be cleaned, the controller first determines the roller to be cleaned. The roller's position and corresponding code are pre-entered into the controller. The controller then sends a command to the pneumatic slide 1, which moves the slider 2 to the side above the roller to be cleaned. The electric telescopic rod 3 is then used to adjust the height of the U-shaped frame 4 so that the cylindrical trough 5 is directly above the roller to be cleaned. At this point, the scraper 8 with the elastic plastic scraper blade inside the cylindrical trough 5 is in close contact with the roller to be cleaned. The motor 6 is then started, which drives the rotating shaft 7 to rotate, thereby driving the scraper 8 and the elastic plastic scraper blade to rotate and clean the roller to be cleaned. After cleaning, air is supplied to the airway chamber of the cylindrical trough 5 through the air pump and air pipe, and then discharged through the air outlet to purge the roller.
[0031] Some rollers are located at the left and right extreme positions inside the rolling mill. Under normal circumstances, the rollers opposite to the opening direction of the cylindrical groove 5 cannot be cleaned. In this case, the relative position of the rack 11 can be adjusted by adjusting the bolt 12. The rack 11 meshes with the gear 10, and the gear 10 drives the crossbar 9 and the cylindrical groove 5 to rotate synchronously, thereby changing the direction of the notch of the cylindrical groove 5, so that the rollers at different positions in the aluminum strip rolling mill can be cleaned.
