Description

Technical Field

[0001] The present invention relates to the technical field of dirt cleaning, and particularly to a roll coating cleaning device for color coated steel plates. Background Art

[0002] During the roll coating process of color coated steel plates, the main purpose of cleaning the surface of the guide roller is to ensure the coating uniformity and product quality. Cleaning can remove dust, oil stains or residual coatings on the guide roller, avoiding problems such as scratches, bubbles or color differences caused by the transfer of impurities to the steel plate surface. At the same time, a clean guide roller can reduce the frictional resistance during the coating process, maintain a stable coating pressure and film thickness control, and prevent coating thickness unevenness or missed coating defects caused by the accumulation of foreign objects. In addition, regular cleaning can extend the service life of the guide roller, reduce the risk of abnormal equipment shutdown, and ensure the continuous and efficient operation of the production line.

[0003] In the prior art, during the roll coating process of color coated steel plates, the method of cleaning the surface of the guide roller adopts the form of direct flushing or soaking and cleaning after disassembly. However, the form of direct flushing is prone to cleaning dead corners and has low efficiency, requiring a large amount of human resources. On the other hand, through the form of disassembly and soaking, it is difficult to completely remove the stubborn stains adhering to the surface, and the tools used for brushing will also cause secondary pollution problems in the subsequent cleaning process due to untimely cleaning. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a roll coating cleaning device for color coated steel plates to solve the problems raised in the above background art. The present invention has a consistent cleaning effect on any area, and can further improve the cleaning intensity through the internally rotatable annular sponge brush, improving the cleaning efficiency and accelerating the discharge process of stains. It can perform extrusion drainage treatment on the sponge brush part used for brushing inside, and this process can complete multiple extrusion drainages within a short moving distance, achieving a self-cleaning effect while also improving the self-cleaning efficiency, and avoiding secondary pollution problems in the subsequent process due to untimely cleaning.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A roll coating cleaning device for color-coated steel plates, including a cleaning device body.

The lead screw passes through the inside of the threaded sleeve.

[0010] Furthermore, the bottom of the support frame is pressed on the surface of the cleaning table. One end of the guiding rod is connected to a water injection pipe, and a valve is installed on the surface of the water injection pipe. The inner side of the support collar is installed on the surface of the linkage sleeve through an embedded bearing.

[0011] Furthermore, the washing component includes a cleaning sleeve, a driven gear, a scraper, and a pressing ring. A spring rod is welded to the end of the cleaning sleeve.

[0027] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] Please refer to Figures 1 to 7, the present invention provides the following technical solution: A roll coating cleaning device for color coated steel plates, including a cleaning device body. The cleaning device body includes a cleaning table 1, a driving mechanism 2, a pushing component 3, and a scrubbing component 4. End plates 5 are welded to both ends of the cleaning table 1. A guiding rod 12 is inserted into the top of the end plate 5. A driving mechanism 2 is inserted between the inner walls of the two end plates 5. A pushing component 3 is sleeved on the surface of the driving mechanism 2. A driving gear 22 is installed in the middle of the pushing component 3. A scrubbing component 4 is welded to the top of the pushing component 3. The scrubbing component 4 is sleeved on the surface of the guide roller to be cleaned. A driven gear 25 is embedded in the scrubbing component 4. The top of the driving gear 22 passes from the bottom of the scrubbing component 4 towards the inside and meshes with a part of the driven gear 25. A sponge brush 26 is attached to the inner wall of the driven gear 25. The sponge brush 26 is integrally in a ring structure, and the inner side of the sponge brush 26 is in contact and fit with the surface of the guide roller to be cleaned. The number of the guiding rods 12 is two. A gap is provided between the side of the scrubbing component 4 and the surface of the guiding rod 12. This cleaning device is used to clean the surface of the guide roller for roll coating during the processing of color coated steel plates.

[0029] When the present invention is used, first control the pushing component 3 and the scrubbing component 4 to move to a position close to one of the end plates 5 through the driving mechanism 2. Then, the disassembled guide roller to be cleaned can be horizontally passed through the inside of the scrubbing component 4, and both ends are supported and placed through the support plate 11. Then start the driving mechanism 2 at the bottom. Drive the pushing component 3 to perform a translational movement through the driving mechanism 2, and further drive the scrubbing component 4 at the top to move through the pushing component 3. During the movement of the scrubbing component 4 along the surface of the guide roller to be cleaned, in cooperation with the spray holes 13 on the guiding rod 12, the cleaning liquid is sprayed onto the surface of the guide roller to be cleaned. Then, with the effects of flushing, scraping by the scraper 16, and rotational scrubbing of the inner sponge brush 26, the cleaning process of the guide roller to be cleaned can be completed. And after the scrubbing component 4 moves to the end, the self-cleaning purpose of a part of the inner sponge brush 26 can be automatically achieved.

[0030] In this embodiment, a support plate 11 is welded to the inner top of the end plate 5. The support plate 11 is used to provide support for the central rod part of the guide roller to be cleaned. The driving mechanism 2 includes a motor 6, a lead screw 7, and a linkage shaft 9. The motor 6 is screwed on the outside of one of the end plates 5. The output end of the motor 6 is inserted with a lead screw 7. Transmission gear sets 8 are installed on the surfaces of the lead screw 7 and the linkage shaft 9, and the linkage shaft 9 performs a rotational movement through the transmission gear sets 8. A rib 10 is embedded on the surface of the linkage shaft 9, and both ends of the linkage shaft 9 and the end of the lead screw 7 are embedded into the inner wall of the end plate 5 through bearings.

[0031] Specifically, after driving the driving motor 6, the lead screw 7 is driven by the motor 6 to rotate. The transmission gear set 8 on the lead screw 7 can directly control the top linkage shaft 9 to rotate synchronously. In this process, the entire pushing assembly 3 can be driven to perform a translational movement by the cooperation of the lead screw 7 and the threaded sleeve 19. The linkage shaft 9 cooperates with the pushing assembly 3 to drive the driven gear 25 inside the cleaning assembly 4 and the sponge brush 26 inside the driven gear 25 to perform a rotational movement, achieving the driving purpose of the entire cleaning process.

[0032] In this embodiment, the pushing assembly 3 includes a support frame 18, an extension plate 20, and a driving gear 22. A threaded sleeve 19 is provided at the bottom of the support frame 18. An extension plate 20 is welded to the side of the support frame 18, and a support collar 23 is welded to the front end of the extension plate 20. An integrated linkage sleeve 21 is formed in the middle of the driving gear 22. The linkage sleeve 21 is sleeved on the surface of the linkage shaft 9, and the protrusions 10 on the surface of the linkage shaft 9 are embedded in the grooves 31 opened on the inner wall of the linkage sleeve 21. The lead screw 7 passes through the inside of the threaded sleeve 19. The bottom of the support frame 18 is pressed on the surface of the cleaning table 1. One end of the guide rod 12 is connected to a water injection pipe 14, and a valve is installed on the surface of the water injection pipe 14. The inner side of the support collar 23 is installed on the surface of the linkage sleeve 21 through an embedded bearing. By a single driving mechanism 2, the pushing assembly 3 and the cleaning assembly 4 on the surface are controlled to perform a translational movement, so that the surface of the horizontally placed roller to be cleaned can be washed, scraped, and rinsed, making the cleaning effect of any area consistent, and the cleaning intensity can be further improved by the rotatable internal annular sponge brush 26.

[0033] Specifically, in the pushing assembly 3, the cleaning assembly 4 above is supported by the bottom support frame 18. The top end of the support frame 18 is directly welded and fixed to the surface of the cleaning sleeve 15. Therefore, after the cooperation of the threaded sleeve 19 and the lead screw 7, the entire pushing assembly 3 can be used to drive the cleaning assembly 4 to synchronously perform a translational movement along the surface of the roller to be cleaned. At the same time, the linkage sleeve 21 in the pushing assembly 3 and the driving gear 22 on the linkage sleeve 21 are driven to rotate by the linkage shaft 9.

[0034] In this embodiment, the scrubbing assembly 4 includes a cleaning sleeve 15, a driven gear 25, a scraper 16, and a pressing ring 29. A spring rod 28 is welded to the end of the cleaning sleeve 15. The spring rod 28 passes through the surface of the scraper 16, and a limiting convex plate 34 is integrally formed at the end of the spring rod 28. A push rod 24 is welded to one side of the scraper 16, and the pressing ring 29 is welded to the other end of the push rod 24. The number of the scrapers 16 and the pressing rings 29 is two each, and the scrapers 16 and the pressing rings 29 are symmetrically installed on both sides of the cleaning sleeve 15. A plug-in piece 27 is welded to the side of the driven gear 25, and a plug-in groove 35 is formed on the inner wall of the cleaning sleeve 15. The plug-in piece 27 is used to be embedded into the inside of the plug-in groove 35. The pressing ring 29 is aligned with the side of the sponge brush 26. Spray holes 13 and grooves 31 are formed on the surface of the diversion rod 12. A compression spring 32 is installed inside the groove 31, and a ball 33 is fixed to the end of the compression spring 32. A convex ring 30 is attached to the edge of the scraper 16. The convex ring 30 is used to abut against the surface of the ball 33, and after the scraper 16 moves translationally, the ball 33 is squeezed by the cooperation of the convex ring 30. The cleaning liquid passes through the spray holes 13 and is sprayed onto the surface of the roller to be cleaned inside the diversion rod 12. A notch 17 is formed at the bottom of the cleaning sleeve 15, and the driving gear 22 passes through the notch 17. Scrapers 16 are symmetrically arranged at both ends of the scrubbing assembly 4. Therefore, during the process of translating towards any one end, the stubborn stains adhering to the surface of the roller can be directly pushed by scraping and discharged directly towards the two end regions, improving the cleaning efficiency and accelerating the discharge process of the stains.

[0035] Specifically, when the cleaning sleeve 15 moves along the surface of the roller to be cleaned, the stains on the surface of the roller to be cleaned are scraped and cleaned by the side scraper 16 on the side, and the driving gear 22 at the bottom cooperates with the driven gear 25 to drive the sponge brush 26 inside the driven gear 25 to rotate, achieving the purpose of rotating scrubbing the surface of the roller to be cleaned. After the scrubbing assembly 4 moves to one end of the roller to be cleaned, all the scraped stains can be pushed out to achieve the discharge purpose.

[0036] Two diversion rods 12 are arranged on the top of the cleaning table 1. With the cooperation of the diversion rods 12 and the convex ring 30 at the edge of the scraper 16, the overall telescopic movement of the scraper 16 can be controlled periodically, and the sponge brush 26 part for scrubbing inside can be squeezed and drained by means of this effect. This process can complete multiple squeezing and draining processes within a short moving distance, achieving the self-cleaning effect and improving the self-cleaning efficiency at the same time, avoiding the problem of secondary pollution in the subsequent cleaning process due to untimely cleaning.

[0037] Specifically, after the control washing assembly 4 is moved to one end of the roller to be cleaned, the convex ring 30 at the edge of the scraper 16 will be abutted against one side of the outwardly convex ball 33. By the block of the ball 33, the entire scraper 16, the ejector rod 24, and the extrusion ring 29 are controlled to approach the sponge brush 26 part on the inner side, and finally the sponge brush 26 part is extruded. At this time, blocked by the sponge brush 26, the pushing force of the convex ring 30 on the ball 33 increases, and finally the ball 33 is pressed towards the inside of the groove 31, and the compression spring 32 is contracted until the convex ring 30 passes over the ball 33. Then, the scraper 16 and the extrusion ring 29 can be pushed back by means of the spring rod 28 until they move to the position where the convex ring 30 abuts against the next ball 33, and the above process can be repeated to achieve the purpose of extruding and discharging the sewage from the sponge brush 26 multiple times in a short time.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0039] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
