Description

Technical Field

[0001] This utility model relates to the field of surface cleaning technology for pinch rollers, and in particular to a mechanism for cleaning impurities from the surface of pinch rollers. Background Technology

[0002] Pinch rollers are common equipment in continuous production lines in metallurgy, papermaking, and textiles. They are mainly used to apply a certain clamping force and traction force to strip materials (such as steel plates, aluminum foil, paper, and fabrics) to ensure that the materials maintain stable tension and speed during processing.

[0003] Currently, when traction is performed on strip, the strip is passed between two conveyor rollers. The clamping force of the upper and lower rollers pulls the material forward, assisting in the stable operation of the production line and preventing the strip from becoming loose or overstretched. However, during the transfer of strip via the conveyor rollers, the strip may carry oil, metal shavings, dust, and chemical coatings. Some of these residues will adhere to the roller surface when passing between the two conveyor rollers. If the roller surface has hard particles (such as welding slag, metal shavings, dust, and oxide scale), they may be pressed into the material surface during clamping, causing scratches, dents, or contamination, thus affecting the quality of the finished product. If oil or chemical residues adhere to the roller surface for a long time, it will reduce the adhesion between the roller surface and the material. The friction between the rollers causes the strip to slip or become unstable in tension when passing over the upper and lower rollers. In the existing technology, after the pinch rollers have been used for a period of time or when there are obvious hard particles, oil stains or chemical residues on the surface, the on-site workers will use a spray gun to evenly spray an agent targeting oil stains and chemical residues on the roller surface. After spraying, a soft brush or nylon scraper is used to scrape off the agent on the roller surface. At this time, the oil stains, chemical agents and hard particles attached to the roller surface are removed together. After the roller surface dries naturally, the cleaning of the roller surface is completed. However, this process requires manual intervention, which consumes a lot of manpower and resources and increases the time required for cleaning the roller surface. Utility Model Content

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5 One embodiment of this utility model provides: a mechanism for cleaning impurities from the surface of a pinch roller, comprising:

[0029] The support frame 1 has two pinch rollers 2 mounted on one side via a drive motor. The support frame 1 provides space and support for the installation of the two pinch rollers 2. When the strip (such as steel plate, aluminum foil, paper and cloth) passes between the two pinch rollers 2, the synchronously rotating pinch rollers 2 can provide power to the strip and apply a certain clamping force and traction force to the strip, ensuring that the strip maintains stable tension and speed during processing (this is existing technology and will not be described in detail here).

[0030] Both pinch rollers 2 have slidingly mounted movable plates 4 on their outer walls, with the two pinch rollers 2 located between the two movable plates 4. Connecting plates 7 are fixedly mounted at both ends of the two movable plates 4. Connecting ear plates 12 are provided on both sides of the two movable plates 4. Each connecting ear plate 12 has two mounting holes on its outer wall. Limit bolts can be detachably installed in the cavities of all four mounting holes. The outer walls of the four connecting plates 7 have through holes that match the limit bolts. One of the two movable plates 4 is located directly above the two pinch rollers 2, and the other is located between the two pinch rollers 2. Directly below, one end of the connecting plate 7 at both ends of one of the movable plates 4 is attached to one end of the connecting plate 7 at both ends of the other movable plate 4. One side of the two connecting ear plates 12 is attached to the outer wall of the two adjacent connecting plates 7. At the same time, limit bolts are inserted into the inner cavity of the four through holes. The small ends of the four limit bolts are fitted with limit nuts through thread engagement. With the cooperation of the four limit bolts and limit nuts, the two adjacent connecting plates 7 can be limited and connected, and finally the two movable plates 4 located outside the two pinch rollers 2 are connected and limited.

[0031] Spray pipes 5 are fixedly installed on one side of each of the two movable plates 4. Multiple spray heads are fixedly installed on the outer wall of each of the two spray pipes 5. A transmission pipe 11 for the transmission of cleaning fluid is fixedly installed at one end of each of the two spray pipes 5. When the two movable plates 4 are connected to each other through two connecting lugs 12, the ends of the two transmission pipes 11 away from the spray pipes 5 are tightly fitted together. Then, a U-shaped clamp is fitted onto the outside of the ends of the two transmission pipes 11 that are fitted together. The two transmission pipes 11 can be connected by the U-shaped clamp, which prevents the cleaning fluid from leaking from the connection point when passing through the two transmission pipes 11, thus improving the sealing between the two transmission pipes 11.

[0032] One end of one of the spray pipes 5 is fixedly installed with a connector 3 for providing cleaning fluid. When it is necessary to spray cleaning fluid (such as acetone and white oil) on the outer surface of the two pinch rollers 2, first connect the spraying equipment to the end of the connector 3 away from the spray pipe 5 through a hose (which can be done by threaded connection or flange connection). Then start the spraying equipment so that the cleaning fluid in the spraying equipment is transferred to the hose through the water pump, and enters the inner cavity of the spray pipe 5 connected to the connector 3 through the hose and connector 3. Then it enters the inner cavity of the other spray pipe 5 through two interconnected transmission pipes 11. Then the cleaning fluid in the inner cavities of the two spray pipes 5 is sprayed onto the roller surface through multiple spray heads.

[0033] A drive motor is fixedly installed on one side of the inner cavity of the support frame 1. A threaded rod 6 is fixedly installed on the power output end of the drive motor. A drive block 8 is detachably installed on one side of one of the movable plates 4. The outer wall of the drive block 8 is provided with a threaded hole that matches the threaded rod 6. When spraying cleaning liquid on the outer surface of the two pinch rollers 2, the drive motor is started to make the two pinch rollers 2 rotate synchronously. Then the drive motor is started to make the threaded rod 6 rotate. At this time, with the cooperation of the threaded hole, the two movable plates 4 can move along the axis of the threaded rod 6. With the movement of the movable plates 4 and the rotation of the pinch rollers 2, the cleaning liquid can be evenly sprayed on the outer surface of the pinch rollers 2.

[0034] One end of the drive block 8 is connected to the outer wall of one of the movable plates 4 by means of threads or snaps, so that the drive block 8 can be connected to and separated from the movable plate 4.

[0035] Both movable plates 4 and spray pipes 5 are bent (e.g.) Figure 3 As shown, the sidewalls of the two movable plates 4 can be attached to the outside of the pinch roller 2, reducing the straight distance between the side of the movable plate 4 close to the outer wall of the pinch roller 2 and the outer wall of the pinch roller 2, preventing the cleaning liquid sprayed from multiple spray heads from splashing to the outside of the pinch roller 2, so that the cleaning liquid can be sprayed evenly on the outer surface of the pinch roller 2.

[0036] Both movable plates 4 are detachably equipped with scrapers 9 for scraping the cleaning fluid from the roller surface. The scrapers 9 are bent, and the degree of bending is the same as that of the movable plates 4. When the movable plates 4 move along the axis of the threaded rod 6, the end of the scraper 9 away from the movable plates 4 comes into contact with the outer wall of the pinch roller 2, thereby scraping off the cleaning fluid, grease, chemical residues and hard particles (such as welding slag, metal shavings, dust, powder and oxide scale) adhering to the outer wall of the pinch roller 2. At the same time, due to the bent design of the scraper 9, the contact area between the scraper 9 and the outer surface of the pinch roller 2 can be increased, thereby improving the efficiency of scraping off the cleaning fluid, grease, chemical residues and hard particles.

[0037] The scraper 9 is made of nylon material, which allows one end of the scraper 9 to make soft contact with the outer wall of the pinch roller 2, thus preventing the scraper 9 from scratching the outer wall of the pinch roller 2 and protecting the outer surface of the pinch roller 2.

[0038] Multiple through holes are provided on one side of the two movable plates 4. Screws 10 can be detachably installed in the inner cavity of the multiple through holes. The outer wall of the scraper 9 is provided with threaded grooves that are compatible with the screws 10. The connection between the movable plate 4 and the scraper 9 can be achieved by the cooperation of multiple screws 10 and multiple threaded grooves. When the scraper 9 needs to be replaced (e.g., the end of the scraper 9 that contacts the outer surface of the pinch roller 2 is worn out, resulting in a gap between the two), firstly, separate the multiple limiting bolts and multiple limiting nuts, then separate the drive block 8 and the movable plate 4 connected to it, and remove the U-shaped clamp from the outside of the two transmission pipes 11. Next, remove the two movable plates 4 from the outside of the pinch roller 2, and then use a tool to continuously rotate the screws 10 until the multiple screws 10 are completely removed from the inside of the multiple threaded grooves to separate the scraper 9 from the movable plate 4, so as to facilitate the replacement of the scraper 9.

[0039] The moving plate 4, spray pipe 5, scraper 9, spray head and transmission pipe 11 constitute the cleaning component. The cleaning component can spray cleaning liquid on the outer surface of the two pinch rollers 2 at the same time and scrape off the cleaning liquid adhering to the outer surface of the two pinch rollers 2, thereby cleaning the hard particles and oil stains on the outer surface of the two pinch rollers 2 without manual intervention, reducing the manpower and material resources required, as well as the time required for roller surface cleaning, and improving the efficiency of roller surface cleaning.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
