Description

Technical Field

[0001] This utility model belongs to the field of roll cleaning technology, and specifically relates to a cleaning device for preventing scratches on the surface of rolls during hot rolling of titanium plate and strip. Background Technology

[0002] During the production of hot-rolled titanium sheet and strip, impurities such as oxide scale and titanium shavings easily accumulate on the surface of the rolls, causing scratches and defects on the strip surface, affecting product quality. Regular cleaning of the rolls is necessary. However, if the existing rolls are not disassembled for cleaning, impurities are prone to splashing or falling after cleaning, causing secondary pollution to the equipment and the sheet. The rolls need to be disassembled after shutdown and then thoroughly cleaned and maintained. This cleaning and maintenance process is time-consuming, inefficient, and affects normal rolling operations.

[0003] A search revealed a prior art patent announcement number CN222902160U for a roll that facilitates waste removal. This device uses evenly distributed brushes on a cleaning rod to sweep away waste from the surface of the roll body. However, brushes alone are insufficient to remove adhering and compacted impurities from the roll surface; they can only clean easily detachable impurities. Another prior art patent announcement number CN118875851A describes a carbide high-chromium cast iron roll device. This device uses a grinding wheel to grind the surface of the high-chromium roll to remove oxides or other impurities such as rust. However, after the grinding wheel has cleaned the oxides and other impurities, it only uses the grinding wheel to grind the roll surface without a scraper to remove the remaining impurities, resulting in incomplete cleaning. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cleaning device for preventing scratches on the surface of rolls during hot-rolled titanium plate and strip rolling. The device uses a grinding mechanism to grind and clean the impurities and oxide scale adhering to the roll surface, and then uses a scraping mechanism to scrape and clean the roll surface. The impurities that fall off after grinding and scraping are blocked and collected by a slag-blocking mechanism to prevent the fallen impurities from scattering and causing re-contamination. Finally, the impurities in the slag-blocking mechanism are sucked out by a dust suction bucket to complete the cleaning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for cleaning the surface of rolling rolls to prevent scratches during hot rolling of titanium plate and strip includes a rolling mill, rolling rolls, a cleaning mechanism, and a dust collector; the rolling rolls are disposed inside the rolling mill, the cleaning mechanism is disposed on one side of the rolling mill and cooperates with the rolling rolls, and the dust collector is disposed above the rolling mill.

[0007] The cleaning mechanism includes a support plate I, a grinding mechanism, a slag-blocking mechanism, a scraping mechanism, a dust collection hopper, and an air suction pipe. The support plate I is fixed to the outside of the rolling mill. The grinding mechanism is mounted on the support plate I, and the scraping mechanism is located below the grinding mechanism. The slag-blocking mechanism is located below the scraping mechanism. The grinding mechanism, scraping mechanism, and slag-blocking mechanism are connected in cooperation with each other. The dust collection hopper is located inside the slag-blocking mechanism and is connected to the air suction pipe. The upper part of the air suction pipe is connected to a vacuum cleaner. The grinding mechanism grinds and cleans the impurities and oxide scale adhering to the surface of the rolls. Then, the scraping mechanism scrapes and cleans the surface of the rolls. The impurities that fall off after grinding and scraping are blocked and collected by the slag-blocking mechanism to prevent the falling impurities from scattering and causing re-contamination. Finally, the dust collection hopper sucks out the impurities in the slag-blocking mechanism, completing the cleaning process.

[0008] The grinding mechanism includes a connecting seat I, an electric push rod, a grinding roller, a motor I, and a lead screw. The connecting seat I is fixed on a support plate I. An electric push rod is housed within the connecting seat I and is rotatably connected to the connecting seat I. A grinding roller is located at the protruding end of the electric push rod and is rotatably connected to the electric push rod. Connecting rods I are located at both ends of the grinding roller and are rotatably connected to the grinding roller. A connecting seat II is located at the other end of the connecting rod I and is rotatably connected to the connecting seat II. The connecting seat II is located within a positioning seat and is slidably connected to the positioning seat. Two sets of positioning seats are provided, one of which contains a lead screw that engages with the connecting seat II. The unit is equipped with motor I, whose output end is connected to a lead screw. Another set of positioning seats contains a limiting column, which is slidably connected to connecting seat II. Motor I controls the lead screw to rotate. The lead screw cooperates with the positioning seat; the rotation of the lead screw drives the positioning seat to move, which in turn drives connecting rod I to move. Connecting rod I drives the grinding roller to move. An electric push rod adjusts the height of the grinding roller. Through the cooperation of motor I and the electric push rod, the height and ejection position of the grinding roller are adjusted. When grinding and cleaning the roll is required, the grinding roller is adjusted to be close to the roll surface for grinding. During roll operation, the grinding roller is adjusted to be away from the roll to avoid affecting normal rolling operations.

[0009] The slag-blocking mechanism includes a connecting shaft, a motor II, a transmission shaft, a dirt-proof plate, and a slag-blocking plate. The connecting shaft is fixed between two sets of connecting seats II. A connecting plate I is provided on the connecting shaft, and the connecting shaft is rotatably connected to the connecting plate I. A slag-blocking plate is provided below the connecting plate I, and a dust suction hopper is provided inside the slag-blocking plate. A gear II is provided on the connecting shaft, and the gear II is rotatably connected to the connecting shaft. The gear II is also fixedly connected to the connecting plate I. Multiple sets of support plates II are fixed on the connecting shaft. A support rod is provided on one side of the support plate II, and the support rod is fixedly connected to the dirt-proof plate. The motor II is mounted on the support plate II, and the output end of the motor II is connected to the transmission shaft, which is rotatably connected to the support plate II. The drive shaft is equipped with multiple sets of gears I, which mesh with gears II. Motor II controls the rotation of the drive shaft, which drives gear I to rotate. Gear I meshes with gear II, which in turn drives gear II to rotate. Gear II drives connecting plate I to rotate, and connecting plate I drives the slag baffle to rotate. The position of the slag baffle is adjusted by motor II to ensure that it can collect the impurities that fall off after grinding and scraping. The impurities are then sucked out by a dust suction hopper. By setting up a dirt-proof plate, the connecting shaft, motor II, drive shaft, gears I and II are prevented from being contaminated by impurities splashed during cleaning, which would affect the transmission efficiency, increase the overall service life of the mechanism, and reduce the frequency of daily maintenance.

[0010] The scraping mechanism includes connecting rod II, connecting plate II, limiting shaft, spring, scraper, and angle stepper motor. Connecting rod II is located below connecting rod I and is connected to connecting rod I via a pin. The angle stepper motor is located on one side of connecting rod II, and its output end is connected to the scraper to control the scraper's tilt angle. Connecting plate II is fixed between the two sets of connecting rod II. The limiting shaft passes through the anti-fouling plate and is fixedly connected to connecting plate II. A spring is provided between connecting plate II and the anti-fouling plate, and the spring is also sleeved on the limiting shaft. The limiting shaft ensures the position of connecting plate II, and the spring between the anti-fouling plate and connecting plate II ensures that connecting plate II is pushed out. Connecting plate II drives connecting rod II, which in turn drives the scraper and the angle stepper motor. The angle stepper motor controls the scraper's tilt angle and, in conjunction with the spring, pushes it forward, ensuring that the scraper can closely adhere to the roller surface for scraping and cleaning.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] The grinding mechanism adjusts the height and ejection position of the grinding roller. When grinding and cleaning the roll is required, the grinding roller is adjusted to be close to the roll surface for grinding. When the roll is in operation, the grinding roller is adjusted to be away from the roll to avoid affecting normal rolling operations, eliminating the need to disassemble the roll. The slag-blocking mechanism collects the impurities that fall after grinding and scraping, preventing them from scattering and causing re-contamination. The impurities are then sucked out by a dust suction hopper. A dirt-proof plate is installed to prevent impurities from splashing onto the transmission components during cleaning, thus avoiding contamination of the transmission efficiency, increasing the overall service life of the mechanism, and reducing the frequency of daily maintenance. The scraping mechanism controls the tilt angle of the scraper, which, in conjunction with a spring, pushes the scraper forward, ensuring that the scraper is in close contact with the roll surface for efficient scraping and cleaning.
