Description

Technical Field

[0001] This application relates to the field of aluminum alloy cold rolling mill technology, and more particularly to a cleaning device for aluminum alloy cold rolling mill. Background Technology

[0002] Cold rolling mills are one of the common pieces of equipment used for processing aluminum alloy sheets and strips. During the cold rolling process, oil is used to cool and lubricate the aluminum alloy sheets and strips, resulting in a large amount of oil adhering to them. Therefore, it is necessary to clean the oil on the aluminum alloy sheets and strips. The existing cleaning method is to install a liquid blowing device on the cold rolling mill to blow away the oil on the aluminum alloy sheets and strips.

[0003] While existing cold rolling mills can easily scrape away impurities on the surface of aluminum alloys during cold rolling, the cleaning of the aluminum alloy surface by scraping with a single scraper is not efficient. When the scraper needs to be replaced, the timely use of another set of scrapers is not effective, which affects the cleaning efficiency of the clean scraper on the aluminum alloy surface. Utility Model Content

[0004] This application provides a cleaning device for an aluminum alloy cold rolling mill to solve the problem mentioned in the background art that when cleaning the aluminum alloy surface by scraping with a single scraper, the scraping of impurities is only done by a single scraper, and when the scraper needs to be replaced, the other set of scrapers is not used in a timely manner, which is not very effective.

[0005] This application provides a cleaning device for an aluminum alloy cold rolling mill, including a cold rolling mill body. Rolls are rotatably connected to the outer wall of the cold rolling mill body, and aluminum alloy plates are adhered to the surface of the rolls. A servo motor is installed on the outer wall of the cold rolling mill body. A drive gear is fixedly connected to the output end of the servo motor. A connecting gear meshes with the outer wall of the drive gear. A first rotating rod is fixedly connected to the rotation center of the drive gear via a rotating shaft. A second rotating rod is fixedly connected to the rotation center of the connecting gear via a connecting shaft. A first lifting rod is slidably connected to the outer wall of the first rotating rod and slidably connected to the outer wall of the cold rolling mill body. A lifting groove is provided at the connection between the outer wall of the cold rolling mill body and the first lifting rod. A second lifting rod is slidably connected to the outer wall of the second rotating rod. A limit groove is provided at the connection between the outer wall of the first rotating rod and the first lifting rod. A scraper is engaged with the outer wall of the first lifting rod.

[0006] Preferably, a connecting box is fixedly connected to the outer wall of the first lifting rod, a connecting rod is fixedly connected to the outer wall of the scraper and slidably connected to the outer wall of the connecting box, a telescopic rod is engaged with the outer wall of the connecting rod and slidably connected to the inner wall of the connecting box, a telescopic rod is fixedly connected to the outer wall of the telescopic rod and slidably connected to the outer wall of the connecting box, a spring is sleeved on the outer wall of the telescopic rod and fixedly connected to the outer wall of the connecting box, a pull block is fixedly connected to one end of the spring and fixedly connected to one end of the telescopic rod, and a collection box located below the scraper is provided on the outer wall of the cold rolling mill body.

[0007] Preferably, the first rotating rod forms a rotating structure between a servo motor and a drive gear, and the first rotating rod and the second rotating rod rotate in opposite directions.

[0008] Preferably, the first lifting rod forms a lifting structure with the lifting groove through the first rotating rod and the limiting groove. The limiting groove is provided in two sets, and the positions of the two sets of limiting grooves are equidistant from the rotation center of the first rotating rod.

[0009] Preferably, the first lifting rod and the limiting groove are configured in a one-to-one correspondence, and a U-shaped groove is provided at the connection between the inner wall of the first lifting rod and the scraper.

[0010] Preferably, the outer wall contour of the pressing part of the connecting rod and the telescopic rod is inclined, and the outer wall contour of the engaging part of the connecting rod and the telescopic rod is flat.

[0011] Preferably, the scraper is connected to the first lifting rod via a connecting rod and a telescopic rod to form an installation structure, and a slot is provided at the connection point between the outer wall of the connecting box and the connecting rod.

[0012] Beneficial effects:

[0013] Considering that existing cold rolling mills can easily scrape off impurities on the surface of aluminum alloys during cold rolling, but when cleaning the aluminum alloy surface with a scraper, using only a single scraper to remove impurities is not very effective when another set of scrapers is needed to replace the scraper, thus affecting the cleaning efficiency of the clean scraper on the aluminum alloy surface.

[0014] When the scraper needs to be used alternately, the clean scraper can be installed on the second lifting rod first. When the scraper on the first lifting rod needs to be disassembled, the servo motor is turned on, and the rotation of the drive gear drives the connecting gear to rotate. At the same time, the rotation of the drive gear and the connecting gear drives the first rotating rod and the second rotating rod to rotate relative to each other, so that the first lifting rod and the second lifting rod alternately lift and lower, thus achieving the effect of alternating use of the scraper and improving the efficiency of the scraper in cleaning impurities on the surface of the aluminum alloy plate.

[0031] The outer wall of the first lifting rod 9 is fixedly connected to a connecting box 14. The outer wall of the scraper 13 is fixedly connected to a connecting rod 15 that is slidably connected to the outer wall of the connecting box 14. The outer wall of the connecting rod 15 is engaged with a telescopic rod 16 that is slidably connected to the inner wall of the connecting box 14. The outer wall of the telescopic rod 16 is fixedly connected to a telescopic rod 17 that is slidably connected to the outer wall of the connecting box 14. The outer wall of the telescopic rod 17 is sleeved with a spring 18 that is fixedly connected to the outer wall of the connecting box 14. One end of the spring 18 is fixedly connected to a pull block 20 that is fixedly connected to one end of the telescopic rod 17. The outer wall of the cold rolling mill body 1 is provided with a collection box 19 located below the scraper 13.

[0032] The connection box 14 facilitates the easy disassembly and replacement of the scraper 13.

[0033] The first rotating rod 7 forms a rotating structure with the servo motor 4 and the drive gear 5, and the first rotating rod 7 rotates in the opposite direction to the second rotating rod 8.

[0034] It facilitates the driving of the servo motor 4. By driving the rotation of the drive gear 5, the first rotating rod 7 can be easily rotated, which in turn enables the first lifting rod 9 to slide easily.

[0035] The first lifting rod 9 forms a lifting structure with the lifting groove 10 through the first rotating rod 7 and the limiting groove 12. There are two sets of limiting grooves 12, and the positions of the two sets of limiting grooves 12 are equidistant from the rotation center of the first rotating rod 7.
