To meet the production needs of high-flatness sheets, the performance of the cold rolling mill, as the core equipment for cold rolling of metal sheets, is of paramount importance.

[0003] However, in the use of existing technology, during the cold rolling process of sheet metal, impurities adhering to the surface during storage and processing can cause deviations in the cold-rolled thickness of the steel sheet, affecting the quality of the produced products. Therefore, a cold rolling mill for high flatness plates has been proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In the solution of this application: When in use, the dust collection box adopts a split design with a steel plate inserted in the middle, which can simultaneously adsorb and clean the upper and lower surfaces of the steel plate, enhancing the comprehensiveness of cleaning. By using the structure of the dust collection box and the fan, impurities on the surface of the steel plate are adsorbed through negative pressure. At the same time, the limiting box, filter plate and collection box form a closed-loop processing process, realizing the integration of impurity adsorption, filtration and collection, improving the impurity treatment efficiency, avoiding secondary pollution by impurities, and preventing impurities from adhering to the surface of the steel plate, which would affect the cold rolling effect of the steel plate.

One end of the dust collection box 26 is fixedly connected to the input end of the fan 10. The dust collection box 26 consists of two parts, with a steel plate inserted in the middle. The fan 10 creates a negative pressure inside the dust collection box 26 to adsorb and extract impurities from the surface of the steel plate, cleaning the surface of the steel plate. A limit box 16 is fixedly connected to the lower surface of the device body 1. The output end of the fan 10 is fixedly connected to the front of the limit box 16. Three filter plates 17 are provided on one side of the limit box 16. The limit box 16 serves to limit and fix the position of the filter plates 17 and to filter the gas entering the limit box 16.

[0030] Furthermore, such as Figure 3 , Figure 4 As shown, the cleaning device includes a support frame 14. The two ends of the support frame 14 are fixedly connected to the inner wall of the device body 1. Two sliding grooves 25 are opened inside the support frame 14. Two limiting frames 19 with the same structure are arranged inside the support frame 14. The support frame 14 is used to support the position of the limiting frames 19.

[0031] Furthermore, such as Figure 3 , Figure 5 As shown, the support frame 14 has a sliding groove 25 inside, and a slide bar 20 is slidably connected inside the sliding groove 25. One side of the slide bar 20 is fixedly connected to one side of the limiting frame 19. The sliding groove 25 serves to limit the position of the slide bar 20 and the limiting frame 19.

[0032] Furthermore, such as Figure 3 , Figure 4As shown, a rack 21 is fixedly connected to the inner wall of the limiting frame 19, and a gear 22 is rotatably connected to the lower surface of the support frame 14. The outer surface of the gear 22 meshes with the surfaces of the two racks 21. The gear 22 is used to make the two racks 21 and the limiting frame 19 move synchronously.

[0033] Furthermore, such as Figure 3 , Figure 4 As shown, two cleaning blocks 23 are fixedly connected to the lower surface of the limiting frame 19. A lead screw 24 is provided inside the limiting frame 19. One end of the lead screw 24 is fixedly connected to a sprocket 12. The sprocket 12 is used to drive the lead screw 24 to rotate.

[0034] Furthermore, such as Figure 4 , Figure 5 As shown, a first motor 11 is fixedly connected to the front of the device body 1. A cleaning device with the same structure is fixedly connected to the output end of the first motor 11. The outer surfaces of the two sprockets 12 are connected by chain drive. The first motor 11 drives the two sprockets 12 to rotate synchronously through chain drive.

[0035] Furthermore, such as Figure 1 , Figure 3 As shown, a limiting roller 13 is rotatably connected inside the device body 1. A second roller 5 is rotatably connected to the side of the device body 1 away from the limiting roller 13. The second roller 5 is used to clamp the guide steel plate into the device. A second motor 18 is fixedly connected to the back of the device body 1. The output end of the second motor 18 is fixedly connected to one end of the second roller 5. The second motor 18 is used to drive the second roller 5 to rotate.

[0036] Furthermore, such as Figure 1 , Figure 4 As shown, the device body 1 has two limiting grooves 2 inside, and a slider 3 is slidably connected inside each of the two limiting grooves 2. The limiting grooves 2 are used to limit the position of the slider 3. A first roller 4 is set between the two sliders 3. A first spring 6 is fixedly connected to the upper surface of each slider 3. The top end of the first spring 6 is fixedly connected to the inner top wall of the limiting groove 2. The first spring 6 is used to push the slider 3 to move downward. A threaded rod 8 is set inside the slider 3. A nut 9 is threadedly connected to the top end of the threaded rod 8. A second spring 7 is sleeved on the outer surface of the threaded rod 8. The two ends of the second spring 7 are fixedly connected to the lower surface of the nut 9 and the upper surface of the device body 1, respectively.

[0037] The operation of the cold rolling mill for high-flatness plates provided by this utility model is as follows: During operation, the steel plate to be cold-rolled is placed between the two limiting rollers 13 on the right side of the device. The steel plate is guided and positioned between the two cleaning devices. Then, the first motor 11 is started, driving the sprocket 12 to rotate. Through chain transmission, the two sprockets 12 rotate synchronously, driving the lead screw 24 to rotate. This causes the lead screw 24 to engage in helical transmission with the limiting frame 19, allowing one limiting frame 19 to rotate. The limiting frame 19 and slide bar 20 move back and forth in the front and back directions. Under the limiting action of the slide groove 25 and the supporting frame 14, they move back and forth, driving the rack 21 to rotate. This causes the rack 21 to mesh with the gear 22, which in turn drives the gear 22 to rotate. The gear 22 then drives another limiting frame 19 to move back and forth in the front and back directions, further driving the four cleaning blocks 23 to move back and forth. This causes the cleaning blocks 23 to rub against the surface of the steel plate, cleaning the impurities adhering to its surface. Similarly, the other... The cleaning device rubs and cleans the other surface of the steel plate. Then, the steel plate moves to the left and enters the middle position of the dust collection box 26. The fan 10 is activated, creating a negative pressure environment inside the dust collection box 26 to suck up and clean the impurities on the surface of the steel plate. The impurities are then passed into the limiting box 16, where the filter plate 17 filters the gas, causing the impurities to fall into the collection box 15. The collection box 15 collects the impurities, and then the cleaned steel plate continues to move to the left. The first roller 4 is inserted between the second roller 5, and the second motor 18 is started to drive the second roller 5. The second roller 5 and the first roller 4 then press against the steel plate. The second spring 7 and the first spring 6 limit the slider 3 through the threaded rod 8 and the nut 9, so that the slider 3 is always kept at the same height relative to the first roller 4. This prevents the first roller 4 and the second roller 5 from impacting when there is no clamping object between them when the steel plate is inserted or removed, thus avoiding deformation and damage to the first roller 4 and the second roller 5.
