Description

Technical Field

[0001] This utility model belongs to the technical field of strip steel cleaning devices, and in particular relates to a cleaning device that uses high-pressure jet to achieve double-sided cleaning of strip steel. Background Technology

[0002] The strip double-sided cleaning device is an automated equipment specifically designed to remove contaminants from both sides of strip steel (such as cold-rolled steel sheets, galvanized sheets, stainless steel strips, etc.). It is widely used in metal processing, automobile manufacturing, and home appliance production to ensure the quality of subsequent strip steel processing (such as coating, welding, stamping). The high-pressure jet cleaning device uses the impact force of the high-pressure jet to clean the surface of both sides of the strip steel, aiming to remove oil, iron filings, oxide scale, and contaminants from the strip steel surface to meet the surface quality requirements of subsequent processing technologies.

[0003] A search revealed Chinese Patent Publication No. CN105880199A, which discloses an abrasive jet double-sided cleaning device and method for steel strip. The device comprises interconnected idler rollers, a cleaning tank, a feed pipe, a high-pressure water inlet pipe, a jet unit, support rollers, a steering roller group, a water spray pipe, and an air knife. The idler rollers are located on the inlet side and fixed to the foundation by a base. The cleaning tank is a box-type steel structure, entirely fixed to the foundation. The method of use is as follows: First, the front and rear sections of the equipment tension the steel strip. Then, the idler rollers support the steel strip. Next, the lower surface of the steel strip is cleaned by cleaning tank #1, and the upper surface is cleaned by cleaning tank #2. The support rollers support the steel strip during cleaning. Then, steering roller #1 turns the original upper surface of the steel strip to face the jet nozzle. The two steering rollers complete the second turning of the steel strip. The water spray pipe cleans the surface of the steel strip, and the air knife blows the surface clean, resulting in a clean steel strip. Its advantages are: it can cleanly and thoroughly remove oil, salt, rust and other adhering substances in one go. The equipment is simple, easy to operate, efficient, energy-saving and environmentally friendly. However, for stubborn impurities, these substances will form a tight bond on the surface of the strip steel. For example, the high-temperature rolling oil remaining during the rolling process will solidify into a viscous film after cooling, and may even seep into the tiny pits on the surface of the strip steel. It is difficult to break through this viscous adsorption by the impact force of the water flow alone. Iron filings or metal particles embedded on the surface of the strip steel will form a local interlock with the strip steel due to long-term compression. The shearing force of the water flow is not enough to peel them off from the base and they cannot be completely removed. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device that uses high-pressure jet to clean both sides of steel strip, aiming to solve the technical problem that stubborn impurities are tightly bonded to the surface of steel strip and cannot be completely removed by the impact of water flow.

[0005] The technical solution of this utility model is implemented as follows: A cleaning device for double-sided cleaning of steel strip using high-pressure jet cleaning includes a body. Multiple scraping mechanisms are equidistantly rotatably connected to the left side of the inner wall of the body. These scraping mechanisms are used for rolling cleaning. Multiple guiding and tidying mechanisms are equidistantly installed in the middle of the inner wall of the body. These guiding and tidying mechanisms are used to tidy and guide the cleaned steel strip. Each scraping mechanism includes a rotating column, which is equidistantly rotatably connected to the left side of the inner wall of the body. Multiple sponge wiping scrapers are equidistantly fixed around the outer wall of the rotating column. A drive assembly is fixedly connected to the top of the body.

[0006] Optionally, the drive assembly includes a motor, which is fixedly connected to the top of the machine body. A connecting column is fixedly connected to the output end of the motor.

A protective shell is fixedly connected to the left side of the inner wall of the machine body.

[0007] Optionally, the guiding and sorting mechanism includes a T-shaped plate, which is equidistantly installed in the middle of the inner wall of the machine body. A long plate is fixedly connected to the middle of an adjacent side of the outer wall of the T-shaped plate.

A double-acting screw is rotatably connected to the upper part of the inner wall of the elongated hollow block. A sliding rod is fixedly connected to the lower part of the inner wall of the elongated hollow block. The upper part of the inner wall of the T-shaped plate is threadedly connected to the outer wall of the double-acting screw. The lower part of the inner wall of the T-shaped plate is slidably connected to the outer wall of the sliding rod. Multiple support plates are fixedly connected at equal intervals to the inner wall of the elongated hollow block.

[0009] Optionally, a bolt is threaded to the outer front end of the machine body, and a warning sign is threaded to the outer wall of the bolt.

[0010] Optionally, a drum is provided on the right side of the outer wall of the machine body, and a motor is fixedly connected to the front end of the outer wall of the drum.

Through the transmission of bevel gears one and two, the rotating column drives the sponge wiping scraper to roll and scrape away impurities. Then, high-pressure jets are sprayed from the high-pressure nozzles on the upper and lower sides of the inner wall of the machine body to clean both sides. After cleaning, the steel strip is wound up and rewound by a drum driven by a motor three.

[0014] In this invention, the second motor starts and drives the worm gear and worm wheel transmission, causing the bidirectional lead screw inside the long hollow block to rotate, which drives the T-shaped plate to slide along the slide bar to adjust the spacing. The long plate on the T-shaped plate moves accordingly, and the roller on the outer wall of the fixed short column rolls the guide steel strip. The support plate supports the bidirectional lead screw to ensure stability.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a cleaning device for double-sided cleaning of steel strip using high-pressure jet cleaning. The device includes a body 1. Multiple scraping mechanisms 2 are equidistantly rotatably connected to the left side of the inner wall of the body 1. These scraping mechanisms 2 are used for rolling cleaning. Multiple guiding and tidying mechanisms 3 are equidistantly installed in the middle of the inner wall of the body 1. These guiding and tidying mechanisms 3 are used to tidy and guide the cleaned steel strip. Each scraping mechanism 2 includes a rotating column 201, which is equidistantly rotatably connected to the left side of the inner wall of the body 1. Multiple sponge wiping scrapers 202 are equidistantly fixed around the outer wall of the rotating column 201. A drive assembly 203 is fixedly connected to the top of the body 1. The drive assembly 203 includes a motor 203. 1. Motor 1 2031 is fixedly connected to the top of the machine body 1. The output end of motor 1 2031 is fixedly connected to a connecting column 2035. Multiple bevel gears 1 2033 are fixedly connected at equal intervals on the outer wall of the connecting column 2035. The bottom of each bevel gear 1 2033 is meshed with a bevel gear 2034. The rear end of the outer wall of bevel gear 2034 is fixedly connected to the front end of the outer wall of the rotating column 201. A protective shell 2032 is fixedly connected to the left side of the inner wall of the machine body 1. A bolt 9 is threadedly connected to the front end of the outer side of the machine body 1. A warning sign 8 is threadedly connected to the outer wall of the bolt 9. The warning sign 8 can remind the staff of the precautions when using and operating the equipment, thereby reducing the probability of accidents.

[0026] Specifically, after the strip enters the machine body 1, it is first scraped and polished by the scraping mechanism 2 on the left side. The motor 1 2031 drives the connecting column 2035 to rotate. Through the meshing transmission of bevel gear 1 2033 and bevel gear 2 2034, the rotating column 201 is driven to rotate, so that the sponge wiping scraper 202 on the outer wall rolls and scrapes the surface of the strip to initially remove impurities. Then, the high-pressure nozzles 11 on the upper and lower sides of the inner wall of the machine body 1 spray high-pressure jets to clean both sides of the strip. The cleaned strip continues to be conveyed and finally wound up by the drum 6 on the right side of the outer wall of the machine body 1. The drum 6 is driven by the motor 3 5 to realize rewinding.

[0027] Reference Figure 1 , Figure 5 and Figure 6 The guiding and sorting mechanism 3 includes a T-shaped plate 301, which is equidistantly installed on the inner wall of the machine body 1. A long plate 302 is fixedly connected to the middle of an adjacent side of the outer wall of the T-shaped plate 301. Multiple fixed short columns 303 are fixedly connected to the bottom of the long plate 302 at equal intervals. A roller 304 is rotatably connected to the outer wall of the fixed short columns 303. A transmission assembly 305 is fixedly connected to the right side of the outer wall of the machine body 1. The transmission assembly 305 includes a second motor 3051, which is fixedly connected to the right side of the outer wall of the machine body 1. A worm gear 3052 is fixedly connected to the output end of the second motor 3051, and a worm wheel 305 is meshed with the bottom of the worm gear 3052. 5. A long hollow block 4 is fixedly connected to the middle of the inner wall of the machine body 1. A two-way screw 3053 is rotatably connected to the upper part of the inner wall of the long hollow block 4. A slide rod 3054 is fixedly connected to the lower part of the inner wall of the long hollow block 4. The upper part of the inner wall of the T-shaped plate 301 is threadedly connected to the outer wall of the two-way screw 3053. The lower part of the inner wall of the T-shaped plate 301 is slidably connected to the outer wall of the slide rod 3054. Multiple support plates 3056 are fixedly connected at equal intervals to the inner wall of the long hollow block 4. A drum 6 is provided on the right side of the outer wall of the machine body 1. A motor 5 is fixedly connected to the front end of the outer wall of the drum 6. Starting the motor 5 can drive the drum 6 to roll up and collect the cleaned strip steel.

[0028] Specifically, after the motor 3051 starts, its output end drives the worm 3052 to rotate. The worm 3052 meshes with the worm wheel 3055, which in turn causes the bidirectional lead screw 3053 inside the elongated hollow block 4 to rotate. Since the upper part of the inner wall of the T-shaped plate 301 is threadedly connected to the outer wall of the bidirectional lead screw 3053, and the lower part of the inner wall is slidably connected to the outer wall of the slide rod 3054, the rotation of the bidirectional lead screw 3053 will drive the T-shaped plate 301 to slide along the slide rod 3054, thereby adjusting the spacing between adjacent T-shaped plates 301. The elongated plate 302 on the T-shaped plate 301 moves with it, and the roller 304 fixed on the outer wall of the short column 303 contacts the strip steel. The roller guides and straightens the strip steel through rolling, ensuring that the strip steel is transported smoothly. The support plate 3056 inside the elongated hollow block 4 supports the bidirectional lead screw 3053, ensuring stable transmission.

[0029] Reference Figure 1 , Figure 2 and Figure 3 High-pressure nozzles 11 are fixedly connected to both the upper and lower sides of the inner wall of the machine body 1. A support short plate 10 is fixedly connected to the left front end of the outer wall of the machine body 1. The support short plate 10 can support the motor 2031. Multiple sliding plates 12 are equidistantly connected to the front side of the outer wall of the machine body 1. A drain pipe 13 is connected to the front bottom of the machine body 1. A sealing cover 7 is rotatably connected to the front end of the outer wall of the drain pipe 13. Tightening the sealing cover 7 can discharge the wastewater collected inside the machine body 1. A rolling long rod 14 is fixedly connected to the right side of the outer wall of the machine body 1. A rolling cylinder 15 is rotatably connected to the outer wall of the rolling long rod 14. The rolling cylinder 15 can reduce the friction when the strip is coiled and reduce the occurrence of damage.

[0030] Specifically, high-pressure nozzles 11 are fixedly connected to the upper and lower sides of the inner wall of the machine body 1. A support short plate 10 is fixedly connected to the left front end of the outer wall of the machine body 1. The support short plate 10 can support the motor 2031. Multiple sliding plates 12 are equidistantly connected to the front side of the outer wall of the machine body 1. A drain pipe 13 is connected to the front bottom of the machine body 1. A sealing cover 7 is rotatably connected to the front end of the outer wall of the drain pipe 13. Tightening the sealing cover 7 can discharge the wastewater collected in the cleaning inside the machine body 1. A rolling long rod 14 is fixedly connected to the right side of the outer wall of the machine body 1. A rolling cylinder 15 is rotatably connected to the outer wall of the rolling long rod 14. The rolling cylinder 15 can reduce the friction when the strip is coiled and reduce the occurrence of damage.

[0031] Working principle: After the strip enters the machine body 1, it is first scraped and polished by the scraping mechanism 2 on the left side. The motor 1 2031 drives the connecting column 2035 to rotate. Through the meshing transmission of bevel gear 1 2033 and bevel gear 2 2034, the rotating column 201 is driven to rotate, so that the sponge wiping scraper 202 on the outer wall rolls and scrapes the surface of the strip to initially remove impurities. Then, the high-pressure nozzles 11 on the upper and lower sides of the inner wall of the machine body 1 spray high-pressure jets to clean both sides of the strip. The cleaned strip continues to be conveyed and finally wound up by the drum 6 on the right side of the outer wall of the machine body 1. The drum 6 is driven by the motor 3 5 to realize rewinding.

[0032] After the motor 3051 starts, its output end drives the worm 3052 to rotate. The worm 3052 meshes with the worm wheel 3055, which in turn causes the bidirectional lead screw 3053 inside the elongated hollow block 4 to rotate. Since the upper part of the inner wall of the T-shaped plate 301 is threadedly connected to the outer wall of the bidirectional lead screw 3053, and the lower part of the inner wall is slidably connected to the outer wall of the slide rod 3054, the rotation of the bidirectional lead screw 3053 will drive the T-shaped plate 301 to slide along the slide rod 3054, thereby adjusting the spacing between adjacent T-shaped plates 301. The elongated plate 302 on the T-shaped plate 301 moves with it. The roller 304 fixed on the outer wall of the short column 303 contacts the strip steel and guides and organizes the strip steel through rolling, ensuring that the strip steel is transported smoothly. The support plate 3056 inside the elongated hollow block 4 supports the bidirectional lead screw 3053 and ensures stable transmission.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
