Detailed implementation manners
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0019] After the rolling mill roll has been used for a long time, some foreign matters will also adhere to its surface, and it needs to be cleaned regularly to ensure the good use performance of the rolling mill roll; since the rolling mill roll is relatively heavy, if it is directly disassembled for cleaning, it is undoubtedly cumbersome and extremely inconvenient. Therefore, the general method is to manually use a scraper to remove the foreign matters on the rolling mill roll, and then use a wet sponge brush or other items to clean the rolling mill roll to ensure the cleanliness of the rolling mill roll. However, this method is undoubtedly laborious, and after cleaning a part, it is necessary to rotate the rolling mill roll, which leads to the problem of potential safety hazards.
[0020] Given by Figures 1-9 , the present invention relates to a rolling mill roll cleaning device, including a housing 1. Inside the housing 1, there are a scraper 2 and a cleaning unit. The cleaning unit includes a rotating roll 3 and an elastic ring 4. The rotating roll 3 is rotatably arranged inside the housing 1. A central cavity 5 is formed inside the rotating roll 3. At the end of the rotating roll 3, a liquid inlet pipe 6 with an external one-way valve 7 is connected. A plurality of elastic partition plates 8 are fixed between the elastic ring 4 and the rotating roll 3. Elastic cavities 9 are formed between the rotating roll 3, the elastic ring 4 and adjacent elastic partition plates 8; A communicating pipe 10 with a lower one-way valve 11 is fixed on the rotating roll 3. The elastic cavity 9 is communicated with the central cavity 5 through the corresponding communicating pipe 10. A plurality of liquid outlet holes 12 with upper one-way valves 13 are formed on the elastic ring 4; A plurality of protruding cleaning parts 14 are formed on the outer side of the elastic ring 4. The cleaning parts 14 are located in the middle of adjacent elastic partition plates 8. A driving mechanism is arranged inside the elastic cavity 9; When the elastic ring 4 is stressed, the liquid inside the elastic cavity 9 is ejected through the liquid outlet holes 12, and the driving mechanism is used to make the cleaning part 14 perform a linear motion along the axial direction of the rotating roll 3; When the elastic ring 4 is not stressed, the liquid is transported into the elastic cavity 9 through the liquid inlet pipe 6, and the driving mechanism is reset.
[0021] Designed in this way, during use, the housing 1 is installed below the rolling mill roll, and the elastic ring 4 on the rotating roll 3 abuts against the rolling mill roll, and the scraper 2 also abuts against the rolling mill roll; In this way, during the rotation of the rolling mill roll, the foreign objects on the outer wall of the rolling mill roll are scraped and removed by the scraper 2. After the rolling mill roll rotates, the elastic ring 4 is driven to rotate by static friction, so that the rotating roll 3 rotates. The specific cleaning process is as follows: Taking the clockwise rotation of the rolling mill roll as an example: When the elastic cavity 9 surrounded by the rotating roll 3, the elastic ring 4 and adjacent elastic partition plates 8 is squeezed by the rolling mill roll, under the action of the lower one-way valve 11 and the upper one-way valve 13, the liquid inside the elastic cavity 9 will be ejected through the liquid outlet holes 12, spraying liquid on the area of the rolling mill roll between the rotating roll 3 and the scraper 2. At the same time, as the rolling mill roll rotates, the cleaning part 14 on the elastic ring 4 shifts from the outside of the elastic cavity 9 to the inside of the elastic cavity 9, thus triggering the driving mechanism to act. Under the action of the driving mechanism, the cleaning part 14 shifts in the direction relative to the axis of the rolling mill roll, so as to realize the cleaning process of the rolling mill roll through the cleaning part 14; When the cleaning part 14 above the elastic cavity 9 disengages from the rolling mill roll, under the self-elastic action of the elastic cavity 9, the elastic cavity 9 returns to its original state. During this period, a negative pressure state is formed inside the elastic cavity 9. Under the action of the negative pressure and the lower one-way valve 11 and the upper one-way valve 13, the liquid inside the central cavity 5 enters the inside of the elastic cavity 9 through the communicating pipe 10, and at the same time, the liquid in the external water tank is supplemented into the inside of the central cavity 5 through the liquid inlet pipe 6 to prepare for the next spraying and cleaning.
[0022] It should be noted that there are two spaces in the external water tank, filled with cleaning liquid and clean water respectively. During cleaning, first, one of the spaces provides cleaning liquid for the liquid inlet pipe 6. After cleaning for a certain time with the cleaning liquid, then the other space provides clean water for the liquid inlet pipe 6 to rinse the rolled mill rolls after cleaning. Finally, the liquid inlet pipe 6 is separated from the liquid in the water tank. At this time, only air enters the inside of the liquid inlet pipe 6, and the air is transported through the elastic cavity 9. Its working principle is the same as that of the liquid transportation process, so it will not be elaborated too much. Finally, air flow is ejected through the liquid outlet hole 12, and the rolled mill rolls are air-dried through the air flow. The two sides of the housing 1 do not contact the rolled mill rolls, and the liquid ejected from the liquid outlet hole 12 will also be concentrated inside the housing 1 and will not spill out.
[0023] Considering that the bending degrees of rolled mill rolls with different radii are different, in order to adapt to rolled mill rolls of different sizes, the scraper 2 includes a lower plate body 15 and an upper plate body 16. The lower plate body 15 is fixed inside the housing 1. At least two installation grooves 17 are formed in the lower plate body 15. The structures in the two installation grooves 17 are the same. A telescopic spring 18 and a connecting rod 19 located above the telescopic spring 18 are movably arranged in the installation groove 17, and the connecting rod 19 is fixed to the upper plate body 16.
[0024] With this design, during use, under the action of the telescopic spring 18, the scraper 2 has a certain amount of telescopic displacement, so that the scraper 2 and the elastic ring 4 can always be in contact with the outer wall of the rolled mill roll during installation to adapt to rolled mill rolls with different radii.
[0025] Furthermore, the shape of the connecting rod 19 is an inverted T shape. Flexible pads 20 are symmetrically fixed between the lower plate body 15 and the upper plate body 16. The connecting rod 19 is located between the two flexible pads 20. With this design, the flexible pads 20 can play a protective role to prevent foreign objects from entering between the two flexible pads 20.
[0026] Specifically, a plurality of connecting pipes 10 are arranged in the elastic cavity 9, and the plurality of connecting pipes 10 are arranged along the axial direction of the rotating roll 3.
[0027] Furthermore, the shape of the cleaning part 14 is arc-shaped. A gap channel 21 is formed between the cleaning part 14 and the outer wall of the elastic ring 4, and the liquid outlet hole 12 is located inside the gap channel 21. With this design, when the cleaning part 14, the elastic ring 4 and the rolled mill roll form a surface contact, the liquid ejected through the liquid outlet hole 12 can flow in the gap channel 21 to replenish the cleaning liquid for the cleaning operation in a timely manner.
[0028] It should be noted that structures such as brushes or grinding blocks can be provided on the surface of the cleaning part 14 to ensure the cleaning effect on the rolling mill rolls. Moreover, due to the outward protrusion of the cleaning part 14 itself, the contact force between it and the rolling mill rolls is greater. Therefore, when it offsets, the cleaning force on the rolling mill rolls is greater and the cleaning effect is better. Additionally, a rigid plate body can be provided inside the cleaning part 14 so that a part of the driving mechanism is fixed on the plate body to make the overall offset of the cleaning part 14 more consistent.
[0029] Specifically, a plurality of driving mechanisms are provided in the elastic cavity 9, and the plurality of driving mechanisms are arranged along the axial direction of the roller 3.
[0030] In this device, there are various specific ways to arrange the driving mechanism. Now, two ways are provided for illustration.
[0031] The first implementation manner of the driving mechanism: The driving mechanism includes a main driving block 22 and a secondary groove 23. The main driving block 22 is fixed to the inner wall of the elastic ring 4. The free end of the main driving block 22 forms a main driving inclined surface 24. The secondary groove 23 is formed in the outer wall of the roller 3, and a secondary driving inclined surface 25 is formed in the secondary groove 23. The main driving inclined surface 24 and the secondary driving inclined surface 25 are in parallel cooperation.
[0032] With this design, when the cleaning part 14 is pressed and offsets towards the inner side of the elastic cavity 9, it drives the main driving block 22 to move synchronously. The main driving inclined surface 24 on the main driving block 22 slides along the secondary driving inclined surface 25 in the secondary groove 23, so that the main driving block 22 drives the cleaning part 14 to offset along the axial direction of the roller 3, and a relative displacement occurs between the cleaning part 14 and the rolling mill rolls, thereby realizing the cleaning of the outer wall of the rolling mill rolls through the cleaning part 14.
[0033] It should be noted that the cleaning part 14 occupies as large an area as possible between two adjacent elastic partitions 8, so as to increase the effective cleaning area per time. Moreover, the area on the rolling mill rolls that is not cleaned will be covered and cleaned by the cleaning part 14 during the rotation of the roller 3 for a long time to ensure comprehensive cleaning.
[0034] The second implementation manner of the driving mechanism: The driving mechanism includes an active rod 26 and a wave groove 27. The shape of the active rod 26 is L-shaped. The active rod 26 is fixed to the inner wall of the elastic ring 4. A notch 28 is formed in the outer wall of the roller 3, and the wave groove 27 is arranged in the notch 28. The free end of the active rod 26 is movably arranged in the wave groove 27.
[0035] With this design, its working principle is basically the same as that of the first implementation manner. The difference is that it adopts the wave groove 27. In this way, when the active rod 26 offsets, it will cause the cleaning part 14 to perform a small-range reciprocating motion, thereby improving the cleaning effect on the rolling mill rolls per time.
[0036] Considering that the rolling mill rolls are not easy to disassemble, fixing mechanisms are provided at both ends of the housing 1. The fixing mechanism includes a fixing frame 29, a screw 30, a rotating rod 31, a fixing plate 32 and a guiding rod 33. The fixing frame 29 is fixed to the housing 1. The screw 30 is in threaded cooperation with the threaded hole on the fixing frame 29. The rotating rod 31 is fixed to the screw 30. The screw 30 is rotatably connected to the fixing plate 32. The guiding rod 33 is fixed to the fixing plate 32, and the guiding rod 33 is movably engaged with the rod hole on the fixing frame 29.
[0037] With such a design, during installation, the housing 1 is placed below the rolling mill roll, and then the rotating rod 31 is used to drive the screw 30 to move. The threaded movement of the screw 30 drives the fixing plate 32 to move outwards. The same operation is performed on the other fixing mechanism, so that the two fixing plates 32 respectively abut and are fixed to the inner sides of both sides of the frame of the rolling mill roll, thus realizing the installation process of the housing 1. It can be disassembled when not needed, which is more convenient; a rubber pad can be provided on the fixing plate 32 to improve the stability during fixing.
[0038] As another operation mode of the rotating roll 3 in this device, it is as follows: A locking mechanism for the rotating roll 3 is provided on the housing 1. For example, a bolt is threadedly provided on the housing 1 to fix the outer wall of the rotating roll 3 to prevent it from rotating. In this way, when the rolling mill roll rotates, the immovable cleaning part 14 can directly clean the rolling mill roll, and then the locking mechanism is released, and operations such as flushing and air drying are continued through the rotated rotating roll 3.
[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
