Description

Technical Field

[0001] This application relates to the field of stainless steel strip production technology, and in particular to an adjustable offset oil scraping device. Background Technology

[0002] During the production of stainless steel strip, it needs to be processed by a rolling mill. While passing through the rolling mill, it needs to be sprayed with protective liquids such as rolling oil to cool and protect the stainless steel strip. After rolling, the external rolling oil needs to be removed to avoid affecting subsequent processing.

[0003] The published patent document CN218743967U discloses an adjustable offset oil scraping device, an oil scraping module, and a rolling mill. It includes two sets of oil scraping rollers arranged vertically, each set comprising a track beam, an oil scraping roller box, and an oil scraping roller body. At least one set of oil scraping rollers is an offset type, equipped with an offset adjustment mechanism. This mechanism is positioned on the corresponding track beam and can drive the corresponding oil scraping roller box to move horizontally and longitudinally relative to the track beam. The document also relates to an oil scraping module using this adjustable offset oil scraping device and a rolling mill. By configuring the offset adjustment mechanism, an offset is created between the upper and lower oil scraping roller bodies. During the extrusion operation, the upper and lower surfaces of the strip can form a certain wrap angle on the upper and lower oil scraping roller bodies, improving the oil scraping effect and efficiency. By adjusting the size of this offset to adjust the wrap angle, the contact area between the strip and the roller body surface can be controlled, thus achieving precise and efficient oil scraping.

[0004] When the above devices are in use, after the oil scraper roller body has been in contact with rolling oil for a long time and reaches the cleaning limit, it needs to be squeezed out and cleaned by the staff. However, it cannot be cleaned automatically, which reduces the efficiency of use. Moreover, the oil stains after cleaning cannot be better treated, which may cause pollution. Utility Model Content

It can cooperate with the connecting plate to improve the stability of the connection, while also facilitating disassembly and installation, making it more convenient to use.

[0014] As a preferred technical solution of this application, the scraper has multiple sets of flow grooves inside, and the scraper is inclined.

[0015] By adopting the above technical solution and setting up a flow channel, the oil stains scraped off by the scraper can enter the collection mechanism better along the flow channel during use, making it more convenient to use and improving the removal efficiency.

[0016] As a preferred technical solution of this application, the scraper has an installation groove on the side near the oil scraping roller, and a rubber pad is provided inside the installation groove.

[0017] By adopting the above technical solution and setting the installation groove, the contact effect between the scraper and the oil scraping roller can be improved during use, thereby further improving the cleaning efficiency and enhancing the practicality of the device.

A connecting groove 202 is opened on one side of the connecting frame 201. A flow rack 203 is provided on the side, and a scraper 3 is provided inside the collection mechanism 2. The scraper 3 abuts against the oil scraper roller 101. A connecting pipe 4 is provided at the bottom of one end of each of the multiple flow racks 203. An oil collection chamber 5 is provided on one side of the mill body 1. The bottom of the four sets of connecting pipes 4 is located inside the oil collection chamber 5. A filter mechanism 6 is provided at the bottom of the oil collection chamber 5. The filter mechanism 6 includes a filter box 601.

A connecting plate 204 and two sets of magnetic connectors 8 are provided on both sides of the connecting rack 201. The two sets of connecting plates 204 are respectively installed on both sides of the oil scraper roller 101.

[0028] By setting up oil scraper rollers 101, the stainless steel strip passes through multiple sets of oil scraper rollers 101 during use. The oil scraper rollers 101 scrape off the emulsion and rolling oil on the surface. While the oil scraper rollers 101 are scraping continuously, the scraper 3 set on one side cleans the oil scraper rollers 101, removing the emulsion and rolling oil from the outside. The removed oil enters the interior of the flow rack 203 through the connecting groove 202, and then enters the interior of the oil collection tank 5 through the connecting pipe 4. Then, it enters the interior of the filter mechanism 6 through the oil collection tank 5 for filtration. After filtration, the oil enters the interior of the collection box 7 for collection. The adjustment mechanism 9 set on both sides can change the position of the oil scraper rollers 101 to adjust the offset of the oil scraper rollers 101. In this way, the oil on the outside of the oil scraper rollers 101 can be cleaned, and the oil can be filtered and pre-treated. This improves the cleaning efficiency of the oil scraper rollers 101 and avoids the phenomenon of efficiency reduction due to long-term cleaning, thus improving the practicality of the device. By setting the connecting plate 204, a stable connection can be achieved between the collecting mechanism 2 and the mill body 1 and the oil scraper 101 during use, and it can also follow the offset of the oil scraper 101, making it more convenient to use and improving the practicality of the device.

Inside the filter box 601 are multiple sets of support frames 604, each located at the bottom of the filter screen 603, and the support frames 604 are slidably connected to the filter screen 603. Both sets of magnetic connectors 8 have placement slots 801 inside, and magnets 802 are installed inside the placement slots 801. The scraper 3 has an installation slot 302 on the side near the scraper roller 101, and a rubber pad 303 is installed inside the installation slot 302. By providing the door 602, the filter box can be adjusted during use. The internal multi-set filter screens 603 allow for rapid cleaning and replacement, making them more convenient to use and improving the practicality of the device. The magnetic connector 8 enables a quick connection between the collection mechanism 2 and the mill body 1, and works in conjunction with the connecting plate 204 to enhance connection stability. It also facilitates disassembly and installation, making it more convenient to use. The mounting groove 302 improves the contact effect between the scraper 3 and the oil scraper roller 101 during use, further enhancing cleaning efficiency and improving the device's practicality.

[0030] Reference Figure 1-4The scraper 3 has multiple sets of flow channels 301 inside, and the scraper 3 is set at an angle. By setting the flow channels 301, the oil and dirt scraped by the scraper 3 can enter the collection mechanism 2 better through the flow channels 301 during use, making it more convenient to use and improving the removal efficiency. Both sides of the door 602 and the filter box 601 are provided with connecting parts 605, and both sides of the door 602 are provided with connecting bolts 606. The connecting bolts 606 are threadedly connected to the two sets of connecting parts 605. By setting the connecting parts 605, the door 602 and the filter box 601 can be quickly connected during use, making subsequent disassembly and replacement more convenient and improving the practicality of the device. The multiple sets of filter screens 603 have different filter hole diameters and are arranged longitudinally. By setting the multiple sets of filter screens 603 with different filter hole diameters, the filtration efficiency can be improved, while the filtration pressure of each filter screen 603 can be reduced, improving the practicality of the device.

[0031] Working principle: With the oil scraping rollers 101 in place, the stainless steel strip passes through multiple sets of oil scraping rollers 101 during operation. The oil scraping rollers 101 scrape away the emulsion and rolling oil on the surface. Simultaneously, a scraper 3 on one side cleans the oil scraping rollers 101, removing the emulsion and rolling oil from their exterior. The removed oil enters the flow rack 203 through the connecting groove 202, then flows through the connecting pipe 4 into the oil collection tank 5. From there, it enters the filtering mechanism 6 for filtration. The filtered oil then enters the collection box 7. The internal collection is completed, and the adjustment mechanism 9 on both sides can change the position of the oil scraper 101 to adjust the offset of the oil scraper 101. In this way, the external oil stains of the oil scraper 101 can be cleaned, and the oil stains can be filtered and pre-treated. This can improve the cleaning efficiency of the oil scraper 101 and avoid the phenomenon of efficiency reduction due to long-term cleaning, thus improving the practicality of the device. By setting the box door 602, the multiple sets of filters 603 inside can be cleaned and replaced quickly during use, making it more convenient to use and improving the practicality of the device. By setting the connecting plate 204, a stable connection can be achieved between the collecting mechanism 2 and the rolling mill body 1 and the oil scraper 101 during use, and it can also follow the offset of the oil scraper 101, making it more convenient to use and improving the practicality of the device. By setting the magnetic connector 8, a quick connection can be achieved between the collecting mechanism 2 and the rolling mill body 1, which can cooperate with the connecting plate 204 to improve the stability of the connection, while also facilitating disassembly and installation, making it more convenient to use. Meanwhile, by setting up the flow channel 301, the oil scraped by the scraper 3 can enter the collection mechanism 2 better along the flow channel 301 during use, making it more convenient to use and improving the removal efficiency. In addition, by setting the mounting groove 302, the contact effect between the scraper 3 and the oil scraping roller 101 can be improved during use, further improving the cleaning efficiency and enhancing the practicality of the device; by setting the connector 605, a quick connection between the box door 602 and the filter box 601 can be achieved during use, making subsequent disassembly and replacement more convenient and enhancing the practicality of the device; by setting multiple sets of filter screens 603 with different filter pore sizes, the filtration efficiency can be improved, while the filtration pressure of each filter screen 603 can be reduced, enhancing the practicality of the device.
