Description

Technical Field

[0001] This utility model relates to the field of stainless steel coil cold rolling technology, specifically to a degreasing device for stainless steel coils after cold rolling. Background Technology

[0002] Cold rolling of stainless steel coils is a metal processing technology that refers to further rolling hot-rolled stainless steel coils at room temperature using a cold rolling mill to reduce their thickness, improve surface finish, and enhance dimensional accuracy.

[0003] The prior art discloses a degreasing device for cold-rolled stainless steel coils (publication number CN221869753U), relating to the field of cold-rolled oil cleaning technology for stainless steel coils. It includes a base and a conveying roller and a degreasing roller mounted on the base. The base also includes a scraping assembly comprising two vertical plates symmetrically fixedly connected to the base, with a rotating roller rotatably connected between the two vertical plates. A drive motor is fixedly connected to the front vertical plate, and the output shaft of the drive motor is fixedly connected to one end of the rotating roller. Multiple scrapers are fixedly connected in a ring at equal angles on the outer circumference of the rotating roller. In use, the multiple scrapers rotate periodically, ensuring that each scraper only participates in the scraping work for a short period. Combined with an oil collection trough to collect the cold-rolled oil flowing from the scrapers, this prevents a large amount of cold-rolled oil from accumulating at the point of contact with the degreasing roller, thus ensuring the effectiveness and reliability of the degreasing process.

[0004] The aforementioned roller has multiple scrapers fixedly connected in a ring at equal angles on its outer circumference. When replacing the scrapers, it is necessary to cut between the roller and the scrapers, making the disassembly and replacement of the scrapers quite troublesome and requiring a lot of time to replace them.

[0031] The scraping device 1 includes a degreasing agent nozzle 11. A spray connector 14 is threadedly connected to the top surface of the degreasing agent nozzle 11. A connecting pipe 12 is fixedly connected to the front of the spray connector 14. The connecting pipe 12 is installed at the bottom of the storage box 2. A water pump is installed on the inner wall surface of the storage box 2. The water pump and the connecting pipe 12 are connected, so that the degreasing agent inside the storage box 2 can be extracted. The degreasing agent can be sprayed onto the surface of the stainless steel coil through the degreasing agent nozzle 11. A support component 13 is slidably connected to the bottom of the spray connector 14. An electric push rod 15 is installed on the top of the spray connector 14. The spray connector 14 is installed on the top of the electric push rod 15. The electric push rod 15 can adjust the position of the spray connector 14.

[0032] The support assembly 13 includes a scraping unit and a support unit, which are arranged sequentially from top to bottom.

[0033] The scraping unit includes a scraper 137, which is fixedly connected to the top surface of the connector 136. A threaded rod 139 is fixedly connected to the top surface of the connector 136. A connecting plate 135 is movably connected to the top surface of the connector 136. The connecting plate 135 is installed on the top surface of the electric push rod 15. There are four electric push rods 15, which are arranged in a rectangular shape. The four electric push rods 15 are controlled by a PLC controller, which can adjust the electric push rods 15 on the left and right sides to move up and down together, so as to facilitate the adjustment of the position of the degreasing agent nozzle 11 and the connecting plate 135. A plug rod 138 is fixedly connected to the bottom surface of the connecting plate 135.

[0034] The support unit includes a support frame 131, which is threaded to the top of the support bracket 3. The support frame 131 is movably connected to the surface of the electric push rod 15. The support bracket 3 can determine the position of the support frame 131, thereby determining the position of the electric push rod 15, facilitating disassembly and replacement of the electric push rod 15 and protecting its safety. A connecting platform 132 is fixedly connected to the top surface of the support frame 131, movably connected to the top of the electric push rod 15. The connecting platform 132 and the support frame 131 can determine the position of the electric push rod 15, facilitating disassembly and replacement of the electric push rod 15, protecting its safety, and thus increasing the service life of the electric push rod 15. A metal casing 133 is fixedly connected to the top surface of the connecting platform 132. The front and rear of the metal casing 133... Connecting ears are fixedly connected to both sides of the surface. The connecting ears are slidably connected to the surface of the plug rod 138. The plug rod 138 and the connecting ears can maintain the stability of the connecting plate 135 and keep the scraper 137 stable, which is convenient for scraping and degreasing the stainless steel coil. The connecting table 132 is slidably connected to the inside of the connecting plate 134. The plug metal plate 134 is installed in the middle position of the rotating roller assembly 4. The plug metal plate 134 can determine the position of the rotating roller assembly 4 and the connecting table 132, which can protect the stability of the connecting table 132, facilitate the disassembly and replacement of the connecting table 132, and protect the safety of the connecting table 132. There are two metal shells 133, which are distributed on the left and right.

[0035] When in use, start the two electric push rods 15 on the left end to move downwards. The electric push rods 15 can drive the spray connector 14 to move downwards. The spray connector 14 can slide on the inner wall surface of the metal housing 133 on the left end. The position of the metal housing 133 can be adjusted. When facing stainless steel coils of different specifications, adjust the position of the degreasing agent nozzle 11.

[0036] Start the spray connector 14. The spray connector 14 draws degreasing agent from the inside of the connecting pipe 12 through the connecting pipe 12, so that the degreasing agent enters the degreasing agent nozzle 11 through the connecting pipe 12 and the spray connector 14, and then sprays the degreasing agent onto the surface of the stainless steel coil through the degreasing agent nozzle 11.

[0037] At the same time, the rotating roller assembly 4 can rub the surface of the stainless steel coil, allowing the degreasing agent to mix with the oil stains on the surface of the stainless steel coil, thus performing preliminary degreasing operations on the stainless steel surface.

[0038] When the electric push rod 15 is activated, the internal piston rods of the two electric push rods 15 on the right end drive the connecting plate 135 to move downward. The connecting plate 135 drives the connecting piece 136 and the scraper 137 to move downward through the threaded rod 139, so that the surface of the scraper 137 connects with the surface of the stainless steel coil, thereby enabling the scraping operation of the stainless steel coil.

[0039] When the connecting plate 135 moves downward, it can drive the threaded rod 139 to move downward, so that the threaded rod 139 slides on the inner wall surface of the connecting lug of the metal housing 133, which can maintain the stability of the connector 136 and the scraper 137.
