Description

Technical Field

[0001] This utility model relates to the field of hot rolling mill technology, specifically to a hot rolling mill for aluminum alloy plates. Background Technology

[0002] In the production of aluminum alloy sheets, the hot rolling mill plays a crucial role. The work rolls of the hot rolling mill come into direct contact with the aluminum alloy billet. Under the high temperature and high pressure rolling environment, a large amount of aluminum alloy debris, oxide scale, oil, and other impurities quickly adhere to the surface of the work rolls. The presence of these impurities severely affects the surface quality of the aluminum alloy sheets, leading to defects such as scratches and pits, thus reducing the product's pass rate and market competitiveness.

[0003] Currently, the cleaning of hot rolling mill work rolls mainly relies on manual operation or traditional cleaning equipment. Manual cleaning is not only inefficient, but its effectiveness is also greatly affected by the operator's experience and skill level, making it difficult to guarantee consistency and thoroughness. Furthermore, in the high-temperature, high-dust working environment, manual cleaning poses a significant threat to the operator's health. Traditional cleaning equipment, such as simple mechanical scrubbing devices or chemical cleaning equipment, while improving cleaning efficiency to some extent, still has many limitations. In addition, these traditional cleaning methods cannot achieve real-time online cleaning, requiring machine shutdown for cleaning operations, significantly reducing production efficiency and increasing production costs.

[0004] With the continuous growth of market demand for aluminum alloy sheets and the increasing requirements for product quality, it is of urgent practical significance to develop a hot rolling mill work roll cleaning device that is efficient, reliable, environmentally friendly, and capable of automatic online cleaning.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-2 As shown, a hot rolling mill for aluminum alloy sheets includes a support plate 1, fixed plates 2 on the front and rear end walls of the support plate 1, two hydraulic telescopic rods 3 on the top wall of the support plate 1, a base 4 on the wall between the driving bottom ends of the hydraulic telescopic rods 3, a motor 5 on the front side wall of the base 4, round rods 6 rotatably connected to the inner walls of the front and rear sides of the base 4 via bearings, a cylinder 7 interference fit connected to the outer wall of the round rods 6, multiple brushes 8 on the outer wall of the cylinder 7, a rinsing mechanism on the left side wall of the base 4, and a cleaning mechanism on the right side wall of the base 4.

[0023] Furthermore, the rinsing mechanism includes a connecting plate 10. The outer wall of the connecting plate 10 is mounted on the left side wall of the base 4 via a connecting block 9. Multiple nozzles 11 are provided on the bottom wall of the connecting plate 10, and one end of the liquid inlet pipe 16 is provided on the top wall of the connecting plate 10. After the working roller is brushed by the brush 8 for a certain period of time, the impurities are fully separated from the working roller. The rinsing water is injected into the connecting plate 10 through the liquid inlet pipe 16 and sprayed out through the nozzles 11 to rinse the working roller.

[0024] Furthermore, multiple nozzles 11 are arranged at intervals from front to back at the bottom of the connecting plate 10, and the multiple nozzles 11 can fully cover the outer wall of the working roller, thereby improving the rinsing effect.

[0025] Furthermore, the cleaning mechanism includes a rectangular plate 13. The outer wall of the rectangular plate 13 is mounted on the right side wall of the base 4 via a rectangular block 12. Multiple nozzles 14 are provided on the bottom wall of the rectangular plate 13. One end of an inlet pipe 15 is provided on the top wall of the rectangular plate 13. The cleaning liquid is injected into the rectangular plate 13 through the inlet pipe 15 and sprayed out through the nozzles 14. The cleaning liquid can be evenly sprayed onto the outer wall of the working roller by rotating the working roller, thereby softening and cleaning the impurities on the outer wall of the working roller.

[0026] Furthermore, the rectangular plate 13 is inclined so that the cleaning liquid sprayed from the nozzle 2 14 can evenly cover the outer wall of the working roller.

[0027] Furthermore, the brushes 8 are arranged in a circumferential gap on the outer wall of the cylinder 7. After the motor 5 is started, the rod 6 drives the cylinder 7 and the brushes 8 to rotate. The rotation of the brushes 8 brushes the outer wall of the working roller, separating the impurities from the working roller.

[0028] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0029] One specific application of this embodiment is:

[0030] In actual use of this device, the fixing plate 2 is first firmly installed on the outer wall of the frame at both ends of the hot rolling mill working roll by welding or bolting. This installation method has extremely high stability and can ensure that the entire cleaning device will not shake or shift during operation, laying a solid foundation for subsequent precise cleaning operations.

[0031] When the hot rolling mill work rolls need to be self-cleaned, the hydraulic telescopic rod 3 is activated. The hydraulic telescopic rod 3 then exerts its powerful force to push the base 4 downward at a stable and controllable speed. As a key load-bearing component, the base 4 drives a series of important structures installed on it, such as the motor 5, cylinder 7, brush 8, connecting plate 10, nozzle 11, rectangular plate 13, and nozzle 2 14, to move downward synchronously. During this process, the connection of each component is firm and reliable, ensuring the overall structure's synergy.

[0032] As the base 4 descends, the brush 8 at the bottom of the outer wall of the cylinder 7 gradually approaches and eventually contacts the surface of the working roller. At the same time, the cleaning fluid is injected into the rectangular plate 13 through the inlet pipe 15. The internal structure of the rectangular plate 13 is ingeniously designed to distribute the cleaning fluid reasonably, allowing it to be sprayed evenly through the nozzle 14. Since the working roller is in a continuous rotating state, the cleaning fluid sprayed from the nozzle 14 can quickly and evenly cover the entire outer wall of the working roller under the combined action of centrifugal force and the rotational force of the working roller. This effectively softens the aluminum alloy debris, oxide scale, oil stains and other impurities adhering to the outer wall of the working roller, reduces the adhesion between the impurities and the surface of the working roller, and creates favorable conditions for subsequent cleaning steps.

[0033] While the cleaning solution softens the impurities, the motor 5 is started. The motor 5, as the power source, outputs stable rotational power, causing the rod 6 to rotate. The rod 6 is closely connected to the cylinder 7, which in turn drives the cylinder 7 and the brush 8 fixed to the bottom of its outer wall to rotate at high speed. The high-speed rotating brush 8 performs a fine brushing on the outer wall of the working roller. Under the action of strong friction, the impurities softened by the cleaning solution gradually separate from the surface of the working roller. The rotation speed of the brush 8 is carefully designed to ensure sufficient cleaning power without causing excessive wear on the surface of the working roller.

[0034] After the brush 8 continuously brushes the work roll for a period of time, the impurities have been fully separated from the work roll. At this time, the rinsing water is injected into the connecting plate 10 through the liquid inlet pipe 16. The connecting plate 10 also has an optimized internal flow channel design, which can ensure that the rinsing water is smoothly and evenly sprayed out through the nozzle 11. The spray angle and flow rate of the nozzle 11 have been precisely adjusted, and the sprayed rinsing water can impact the surface of the work roll in all directions and with high intensity, thoroughly washing away the separated impurities and completing the comprehensive self-cleaning operation of the work roll. The entire self-cleaning process is completed in one go, with all components working together to efficiently and reliably ensure the cleaning effect of the hot rolling mill work roll, providing strong support for the high-quality production of aluminum alloy plates.

[0035] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
