Description

Technical Field

[0001] The utility model belongs to the technical field of cold rolling devices, and in particular relates to a cold rolling device with a cleaning function. Background Art

[0002] Cold rolling is a crucial process in the metalworking industry, used to flatten, shape, and strengthen sheet metal. However, during the cold rolling process, oil, metal debris, and other impurities often remain on the surface of the sheet metal. These residues not only affect product quality but can also cause wear and blockage on the cold rolling equipment, shortening its service life.

[0003] Traditional cold rolling mills often only perform cold rolling, requiring additional equipment and processes to clean the metal sheet surface. This not only increases production costs but also reduces efficiency. To address this issue, some cold rolling mills with cleaning functions have emerged on the market. However, these devices are often complex in structure, cumbersome to operate, and offer suboptimal cleaning results.

[0004] For example, some systems use fixed brushes and water sprayers to clean sheet metal. However, due to their fixed positions, they cannot be flexibly adjusted to the thickness and shape of the sheet metal, resulting in poor cleaning results. Furthermore, the cleaning fluid from these systems is often discharged directly into the environment, wasting water resources and potentially polluting the environment.

[0005] Therefore, developing a cold rolling device with a cleaning function that has a simple structure, convenient operation, and good cleaning effect is of great significance for improving the production efficiency and product quality of the metal processing industry. Utility Model Content

A vertical fixing column 12 is fixedly installed between the four corners of the lower end surface of the top plate 9 and the four corners of the upper end of the water collection tank 3. The top plate 9, the water collection tank 3, and the two front fixing columns 12 are fixedly connected to the cold rolling mill 1. A vertical guide groove 13 is provided on the end surface of the two fixing columns 12 on the left side that are close to each other, and a vertical guide groove 13 is provided on the end surface of the two fixing columns 12 on the right side that are close to each other.

[0041] The two sliding seats 4 are both horizontally arranged square plate structures. A guide block 14 is fixedly provided at the left and right ends of the front and rear end surfaces of the two sliding seats 4. The four guide blocks 14 on the sliding seat 4 are respectively slidably engaged in the guide grooves 13 of the four fixed columns 12. The two sliding seats 4 are stably raised and lowered inside the fixed frame 2 through the mutual cooperation between the guide blocks 14 and the guide grooves 13.

[0042] The connecting rod assembly 5 includes a first connecting rod 15, a second connecting rod 16, a third connecting rod 17, and a fixed rod 18. The first connecting rod 15 is hinged to the upper sliding seat 4, and the second connecting rod 16 is hinged to the lower sliding seat 4.

The distance between the fixed rod 18 and the upper and lower sliding seats 4 is equal, and the middle of the fixed rod 18 is hinged to the middle of the third connecting rod 17.

[0043] The cylinder body of the oil cylinder 10 is fixedly mounted at the center of the upper end surface of the top plate 9 of the fixed frame 2. The piston rod of the oil cylinder 10 extends vertically downward through the top plate 9 of the fixed frame 2 and is fixedly connected to the center of the upper end surface of the upper sliding seat 4. The upper sliding seat 4 is raised and lowered by the extension and contraction of the piston rod of the oil cylinder 10. When the upper sliding seat 4 is raised or lowered, the first connecting rod 15 drives the third connecting rod 17 to rotate, and the third connecting rod 17 drives the second connecting rod 16 to rotate. The angle between the first connecting rod 15 and the third connecting rod 17 and the angle between the second connecting rod 16 and the third connecting rod 17 remain equal, thereby causing the upper and lower sliding seats 4 to move closer to or farther away from each other.

[0044] Two left and right hinged seats are fixedly provided on the front end of the lower end face of the upper sliding seat 4, and two left and right hinged seats are fixedly provided on the front end of the upper end face of the lower sliding seat 4. The two ends of the rotating shaft of the two roller brushes 6 are respectively rotatably connected to the upper and lower sets of hinged seats.

[0045] The transmission assembly includes a drive motor 24, a driving gear 25, a driven gear 26, a transmission rod 19, a first bevel gear 20, a second bevel gear 21, a third bevel gear 22, and a fourth bevel gear 23. A vertical transmission rod 19 is rotatably mounted between the top plate 9 of the fixed frame 2 and the left end of the upper end surface of the water collection tank 3. The upper and lower ends of the transmission rod 19 are hingedly connected to the top plate 9 of the fixed frame 2 and the upper end surface of the water collection tank 3, respectively. The middle region of the transmission rod 19 is a hexagonal rod-shaped structure. A vertical through-hole is provided at the left end of each of the upper and lower sliding seats 4, through which the transmission rod 19 passes. A first bevel gear 20 is fixedly mounted at the left end of the rotating shaft of the upper roller brush 6, while a second bevel gear 21 is fixedly mounted at the left end of the rotating shaft of the lower roller brush 6. A third bevel gear 22 is rotatably mounted at the lower end of the socket of the upper sliding seat 4, while a fourth bevel gear 23 is rotatably mounted at the upper end of the socket of the lower sliding seat 4. The third bevel gear 22 meshes with the first bevel gear 20, and the fourth bevel gear 23 meshes with the second bevel gear 21. A hexagonal through-hole extending vertically through the inner walls of the third bevel gear 22 and the fourth bevel gear 23 is provided. The hexagonal through-holes of the third bevel gear 22 and the fourth bevel gear 23 are slidably sleeved on the outer side of the middle area of ​​the transmission rod 19. A drive motor 24 is fixedly mounted on the upper end of the top plate 9 of the fixed frame 2, and the output shaft of the drive motor 24 is vertically downward. A driving gear 25 is fixedly mounted on the output shaft of the drive motor 24, and a driven gear 26 is fixedly mounted on the upper end of the transmission rod 19, and the driving gear 25 meshes with the driven gear 26.

[0046] The drive motor 24 rotates the transmission rod 19 through the intermeshing driving gear 25 and driven gear 26. As the transmission rod 19 rotates, the hexagonal rod structure in its central region cooperates with the hexagonal through-holes to drive the third and fourth bevel gears 22 and 23 to rotate synchronously. The third bevel gear 22 drives the upper roller brush 6 via the first bevel gear 20, while the fourth bevel gear 23 drives the lower roller brush 6 via the second bevel gear 21. When the upper and lower sliding seats 4 move toward or away from each other, the third and fourth bevel gears 22 and 23 slide on the transmission rod 19. Even after the sliding seat 4 stops moving, the transmission rod 19 can still drive the third and fourth bevel gears 22 and 23 to rotate.

[0047] A water spraying member 7 is fixedly mounted in the middle of the adjacent end surfaces of the two sliding seats 4 along the front-to-back direction. The water spraying member 7 is arranged horizontally along the left-right direction. A row of nozzles is mounted on the adjacent end surfaces of the two water spraying members 7. The nozzles in the upper row spray vertically downward, while the nozzles in the lower row spray vertically upward.

[0048] The water supply assembly 11 includes a water tank 27, a submersible pump, a return water pump 29, a water supply pipe 28, and a return water pipe 30. The water tank 27 is fixedly mounted on the upper end surface of the top plate 9 of the fixed frame 2. A submersible pump is installed inside the water tank 27. The outlet of the submersible pump is connected to the water supply pipe 28. The end of the water supply pipe 28 away from the submersible pump is connected to the two water spraying parts 7. A filter is installed at the middle height of the interior of the water collection tank 3. A return water port is installed at the lower end of the side wall of the water collection tank 3. A return water pump 29 is installed on one side of the water collection tank 3. The inlet of the return water pump 29 is connected to the return water port of the water collection tank 3. A return water pipe 30 is installed at the outlet of the return water pump 29. The end of the return water pipe 30 away from the return water pump 29 is connected to the interior of the water tank 27.

[0049] A vertical scraper 8 is fixedly provided at the rear end of each end surface of the two sliding seats 4 close to each other. The scraper 8 is a V-shaped structure, and the V-shaped tip of the scraper 8 faces the front side.

[0050] Two water leakage grooves 31 are provided on the lower sliding seat 4. The front water leakage groove 31 is located below the lower roller brush 6, and the rear water leakage groove 31 is located between the lower water spraying member 7 and the lower scraper 8.

[0051] The working principle of this utility model is:

[0052] When there is no need to clean the cold-rolled steel plate, the piston rod of the oil cylinder 10 is retracted, thereby raising the upper sliding seat 4 to the highest position, and the upper sliding seat 4 drives the lower sliding seat 4 to descend to the lowest position through the connecting rod assemblies 5 on both sides. At this time, the distance between the two sliding seats 4 is the largest, and the distance between the two roller brushes 6 and the two scrapers 8 is the largest. In this way, the roller brushes 6 and the scrapers 8 will not affect the steel plates output by the cold rolling mill 1.

[0053] When the cold-rolled steel plate needs to be cleaned, the piston rod of the oil cylinder 10 is extended, thereby lowering the upper sliding seat 4, and the upper sliding seat 4 drives the lower sliding seat 4 to rise through the connecting rod assemblies 5 on both sides. At this time, the two sliding seats 4 gradually approach each other until the two roller brushes 6 and the two scrapers 8 are in contact with the upper and lower end surfaces of the cold-rolled steel plate. During this process, the third bevel gear 22 and the fourth bevel gear 23 slide on the transmission rod 19.

[0054] The drive motor 24 then rotates the transmission rod 19 through the meshing drive gear 25 and driven gear 26. As the transmission rod 19 rotates, the hexagonal rod structure in its central region interacts with the hexagonal holes, driving the third and fourth bevel gears 22 and 23 to rotate synchronously. The third bevel gear 22, in turn, drives the upper roller brush 6 via the first bevel gear 20, while the fourth bevel gear 23, in turn, drives the lower roller brush 6 via the second bevel gear 21. The counter-rotating upper and lower roller brushes 6 remove impurities from the cold-rolled steel sheet and sweep them to the rear.

[0055] The submersible pump then pumps the cleaning water from the water tank 27 into the upper and lower water spraying members 7 through the water supply pipe 28. The nozzles of the upper and lower water spraying members 7 spray the cleaning water onto the upper and lower end surfaces of the steel plate, thereby flushing away impurities attached to the steel plate. The washed impurities leak through the two leakage grooves 31 on the lower sliding seat 4 into the lower water collection tank 3, where the impurities remain on the filter screen. The filtered cleaning water returns to the water collection tank 3 below the filter screen. The return pump 29 pumps the filtered cleaning water back into the water tank 27 for secondary use.

[0056] After the impurities are washed away, the steel plate continues to move backward, and the backward-moving steel plate maintains sliding contact with the upper and lower scrapers 8, so that the water droplets and impurities remaining on the steel plate are scraped off by the two scrapers 8.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
