Technical Field
[0001] This utility model relates to the field of polishing technology, and in particular to a polishing device for cold-rolled stainless steel coils. Background Technology
[0002] Cold-rolled stainless steel coils are a type of metal material made from hot-rolled stainless steel coils. After pretreatment such as pickling and annealing at room temperature, they are processed through a cold-rolling process. During production, cold-rolled stainless steel coils require polishing equipment to remove scratches, oxide scale, and rough textures generated during cold rolling, while also reducing the adhesion points of corrosive media and extending their service life.
[0003] Chinese Patent CN217097155U discloses an 8K polishing device for stainless steel coils, including a worktable, suction troughs, and felt rollers. An operation panel is mounted on one side wall of the worktable, and an observation window is located on one side of the operation panel. A conveyor belt is positioned at the center of the upper part of the worktable, and the suction troughs are located on both inner side walls of the worktable. This polishing device, through its suction troughs, suction pipes, suction pump, and collection trough, can centrally collect and store waste debris generated during polishing of the steel strip, making cleaning more efficient and convenient. The distance between the polishing device and the steel strip can be freely adjusted via hydraulic rods, support frames, polishing rollers, chains, and a drive motor, improving the polishing quality of the steel strip.
[0004] However, the above technical solution has the following shortcomings: although the device can centrally process the debris, some debris will adhere to the polishing roller during the polishing process and will not easily fall off normally, thus affecting the subsequent polishing process of stainless steel coils.

The blade of the scraper is in contact with the surface of the polishing rollers, one end of the screw is inserted into the rotating connector and rotates, and the other end of the screw has a knob.

[0021] Example 1
[0022] like Figure 1 - Figure 4 As shown in the figure, the cold-rolled stainless steel coil polishing device proposed in this embodiment includes a machine body 1 and a cleaning mechanism; multiple polishing structures are rotatably connected to the machine body 1, and each polishing structure includes two polishing rollers 2 that are distributed vertically and rotate in opposite directions.
[0023] The cleaning mechanism includes multiple mounting plates 3 horizontally arranged on the body 1, two symmetrically distributed guide rods 4 slidably connected to the mounting plates 3, a connecting plate 5 arranged on the guide rods 4, multiple fixed cylinders 6 arranged in a linear array on the connecting plate 5, a spring 7 arranged inside the fixed cylinder 6, a telescopic rod 8 arranged on the spring 7 and slidably connected to the fixed cylinder 6, a scraper 9 arranged on the telescopic rod 8, a screw 10 threadedly connected to the mounting plate 3, a rotating connector 11 arranged on the connecting plate 5, and two locking nuts 13 threadedly connected to the screw 10; the blade of the scraper 9 is in contact with the roller surface of the polishing roller 2, one end of the screw 10 is inserted into the interior of the rotating connector 11 and rotates, and the other end of the screw 10 is provided with a knob 12.
[0024] The machine body 1 is provided with multiple absorption covers 15, which are located on the side of the scraper 9. The machine body 1 is provided with a collection seat 17, and a negative pressure pipe 16 is provided between the absorption covers 15 and the collection seat 17.
[0025] In this embodiment, when the steel coil is polished by the polishing roller 2, the rotation of the polishing roller 2 causes the roller surface to scrape off debris with the scraper 9. The scraper 9 and the roller surface have a certain angle to improve the scraping effect. The spring 7 ensures that the scraper 9 is always in contact with the roller surface to ensure the stability of the scraping. The pressure between the scraper 9 and the roller surface can also be adjusted to ensure the scraping effect. When it is necessary to adjust the pressure of the scraper 9, the screw 10 can be rotated by the knob 12. The screw 10 is screwed into the mounting plate 3 and rotates at one end of the rotating connector 11. Under the guidance of the guide rod 4, the screw 10 will drive the connecting plate 5 to move, thereby adjusting the pressure between the scraper 9 and the roller surface. After adjusting to the appropriate position, the two locking nuts 13 are tightened on both sides of the mounting plate 3 to ensure the stability of the screw 10. The operation is simple and convenient and has good practicality.
[0026] It should be noted that the collection seat 17 adopts the collection box and exhaust fan designed by the utility model with patent announcement number CN216066948U to suck up and collect the debris, and the magnitude of the squeezing force between the scraper 9 and the roller surface can be detected by installing a sensor (not shown).

Compared with the first embodiment, in this embodiment, the mounting plate 3 is provided with fixing plates 18 at both ends. Multiple bolts 19 are provided through the fixing plates 18. The bolts 19 are threaded to the machine body 1. The telescopic rod 8 is provided with four limit sliders 14 arranged in a ring array. The inside of the fixing cylinder 6 is provided with a groove for the limit sliders 14 to slide.
[0029] In this embodiment, the fixing plate 18 and bolt 19 are used to fix and disassemble the mounting plate 3 so that the scraper 9 can be inspected and replaced. The limiting slider 14 plays a guiding and stabilizing role in the movement of the telescopic rod 8 and the extension and retraction of the spring 7, ensuring the stability of the scraper 9 when scraping debris, and at the same time preventing the spring 7 from bending or twisting.

At the same time, the support roller 25 is used to guide and support the conveying of the steel coil. The pressure adjusting roller 26 is provided to ensure the stability of the steel coil conveying and winding. The cylinder 27 can drive the lifting frame 28 to move vertically to adjust the height of the pressure adjusting roller 26 to accommodate the steel coil.
