Description

Technical Field

[0001] This utility model relates to the field of leveling mechanism technology, and in particular to a leveling mechanism for a large-scale thick plate leveling and cross-cutting production line. Background Technology

[0002] The thick plate leveling and shearing production line, also known as a shearing line or leveling line, is mainly used to uncoil, level, cut to length, and stack thick plates into flat plates of the required length. The leveling mechanism is an indispensable component of the thick plate leveling and shearing production line. By leveling the uncoiled plates, the flatness of the thick plates can be ensured, which facilitates the subsequent cutting of the thick plates according to the set length.

[0003] The leveling mechanism of the thick plate leveling and cross-cutting production line mainly applies external force to the plate to cause it to undergo deformation such as stretching, compression, and bending, thereby eliminating internal stress and making the plate flat. However, if foreign objects adhere to the surface of the leveling roller during the leveling process of the thick plate, it will affect the leveling effect of the thick plate.

[0004] The existing publicly available technical solution, CN218775547U, discloses a leveling roller cleaning mechanism for a leveling machine, including an upper pressure mold frame and a lower pressure mold frame. Multiple upper leveling rollers are rotatably connected within the upper pressure mold frame. An upper scraper frame is fixedly connected to the top of the upper pressure mold frame, and multiple upper scraper strips are fixedly connected to the bottom of the upper scraper frame, with the upper scraper strips contacting the upper leveling rollers. The upper pressure mold frame is equipped with a cleaning mechanism that can scrape away residual waste on the rotating leveling rollers using the upper and lower scraper frames, making the cleaning method more convenient. It can also remove waste that falls onto the lower scraper frame, thereby discharging the waste from the leveling machine after cleaning the leveling rollers. Furthermore, a slider can be used to further scrape the upper scraper strips and upper leveling rollers, improving the practicality of the mechanism.

[0005] In actual implementation of the above technical solution, after cleaning the leveling roller, a layer of lubricating oil is brushed onto the surface of the leveling roller to extend the service life of the roller surface. However, the leveling roller is usually directly installed on the leveling device, and the distance between the upper and lower leveling rollers is limited, making it inconvenient to operate the leveling roller. Summary of the Invention

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4 A leveling mechanism for a large thick plate leveling and cross-cutting production line includes a leveling device bracket 1, an upper pressure roller assembly 4 is slidably installed inside the leveling device bracket 1, and a lower pressure roller assembly 5 is provided below the upper pressure roller assembly 4. A lubrication assembly 3 for lubrication is provided on the leveling device bracket 1.

[0029] The upper pressure roller assembly 4 includes an upper pressure roller bracket 402, and an upper pressure roller body 401 is slidably installed inside the upper pressure roller bracket 402. A first movable slider 403 is fixedly provided on the top of the upper pressure roller bracket 402.

[0030] The lower pressure roller assembly 5 includes a lower pressure roller bracket 503, and a lower pressure roller body 502 is rotatably mounted inside the lower pressure roller bracket 503. A second movable slider 504 is fixedly provided at the bottom of the lower pressure roller bracket 503. A connecting groove 501 is provided at the connection between the first movable slider 403 and the second movable slider 504 and the leveling device bracket 1.

[0031] A support plate 6 is fixed inside the leveling device bracket 1 and arranged parallel to the lower pressure roller assembly 5. A lower pressure plate 7 that can move up and down is arranged parallel to the upper pressure roller assembly 4. The telescopic end of the leveling cylinder 2 is fixedly installed on the top of the lower pressure plate 7. Lifting sliders 405 are rotatably installed on both the left and right ends of the upper pressure roller body 401. A lifting groove 404 is provided at the connection between the lifting slider 405 and the lower pressure roller bracket 503.

[0032] By adopting the above technical solution, when leveling the thick plate, the thick plate enters between the lower pressure roller body 502 and the upper pressure roller body 401. The leveling cylinder 2 is activated, and the leveling cylinder 2 pushes the lower pressure plate 7 to move downward. The lower pressure plate 7 can push the lifting slider 405 on the upper pressure roller body 401 to slide downward inside the lifting groove 404. At this time, the distance between the upper pressure roller body 401 and the lower pressure roller body 502 decreases until the thick plate is pressed tightly. The thick plate is between the lower pressure roller body 502 and the bottom. Supported by the support plate 6, the upper pressure roller body 401 is used to level the thick plate. After leveling, the upper pressure roller bracket 402 and the lower pressure roller bracket 503 can be pulled. At this time, the upper pressure roller bracket 402 and the lower pressure roller bracket 503 slide on the connecting groove 501 through the first moving slider 403 and the second moving slider 504 respectively, thereby dragging the upper pressure roller assembly 4 and the lower pressure roller assembly 5 to one side of the leveling device bracket 1, so as to facilitate the cleaning and lubrication of the upper pressure roller assembly 4 and the lower pressure roller assembly 5.

[0033] Specifically, such as Figures 2 to 4 As shown, the lubrication assembly 3 includes a cleaning soft brush 306 installed between the lower pressure roller body 502 and the upper pressure roller body 401. A support rod 305 is fixedly installed on one side of the cleaning soft brush 306, and an oil outlet plate 303 is fixedly installed at the end of the support rod 305. An oil supply pipe 302 is fixedly connected to one side of the oil outlet plate 303, and a lubricating oil tank 301 is fixedly connected to the end of the oil supply pipe 302. Multiple oil outlet nozzles 304 are installed on the surface of the oil outlet plate 303, and the oil outlet nozzles 304 are arranged one-to-one with the lower pressure roller body 502 and the upper pressure roller body 401. Guide sliders 307 are fixedly installed at both ends of the cleaning soft brush 306, and a guide groove 310 is opened at the connection between the guide slider 307 and the leveling device bracket 1. A reset telescopic rod 308 is fixedly installed between the guide slider 307 and the guide groove 310, and a reset spring 309 is sleeved on the outside of the reset telescopic rod 308.

[0034] By adopting the above technical solution, the cleaning soft brush 306 is located on the outside of the lower pressure roller bracket 503 and the upper pressure roller bracket 402. It is particularly important to note that the cleaning soft brush 306 is configured in two ways: one set of cleaning soft brushes 306 is height-matched to the lower pressure roller body 502, while the other set is height-matched to the upper pressure roller body 401. This ensures that the cleaning soft brushes 306 are not squeezed when the lower and upper pressure roller bodies 502 and 401 are leveling the thick plate. When the upper and lower pressure roller assemblies 4 and 5 are pulled out, they gradually approach the cleaning soft brush 306. Once the upper and lower pressure roller assemblies 4 and 5 reach the upper and lower sides of the cleaning soft brush 306 respectively, the cleaning soft brush 306 slides inside the guide groove 310 via the guide slider 307. Simultaneously, the reset telescopic rod 308 and the reset spring 309 extend and retract, thereby allowing the bristles of the cleaning soft brush 306 to... By pressing the upper pressure roller assembly 4 and the lower pressure roller assembly 5 together, respectively, the upper pressure roller assembly 4 and the lower pressure roller assembly 5 can be cleaned. At the same time, the lubricating oil in the lubricating oil tank 301 can flow to the oil outlet plate 303 through the oil supply pipe 302 and be sprayed out by the oil outlet nozzle 304. The direction of the oil outlet nozzle 304 can be set according to whether the upper pressure roller assembly 4 or the lower pressure roller assembly 5 is being lubricated. At this time, the lubricating oil is sprayed onto the upper pressure roller assembly 4 and the lower pressure roller assembly 5 through the oil outlet nozzle 304. 5. Lubricate the upper pressure roller assembly 4 and the lower pressure roller assembly 5. When pushing the upper pressure roller assembly 4 and the lower pressure roller assembly 5 back, the cleaning soft brush 306 can move on the upper pressure roller body 401 and the lower pressure roller body 502, thereby applying lubricating oil to the surface of the upper pressure roller body 401 and the lower pressure roller body 502. When the upper pressure roller body 401 and the lower pressure roller body 502 are pulled to move, the cleaning and lubrication of the upper pressure roller body 401 and the lower pressure roller body 502 can be achieved.

[0035] Working principle: When leveling a thick plate, the plate enters between the lower pressure roller body 502 and the upper pressure roller body 401. The leveling cylinder 2 is activated, pushing the lower pressure plate 7 downwards. The lower pressure plate 7, in turn, pushes the lifting slider 405 on the upper pressure roller body 401 to slide downwards within the lifting groove 404. This reduces the distance between the upper pressure roller body 401 and the lower pressure roller body 502 until the thick plate is pressed tightly. Supported by the lower pressure roller body 502 and the bottom support plate 6, the plate is leveled in conjunction with the upper pressure roller body 401. After leveling, the upper pressure roller bracket 402 and the lower pressure roller bracket 503 can be pulled. The upper pressure roller bracket 402 and the lower pressure roller bracket 503 slide on the connecting groove 501 via the first moving slider 403 and the second moving slider 504, respectively, thus dragging the upper pressure roller assembly 4 and the lower pressure roller assembly 5 to one side of the leveling device bracket 1. The upper pressure roller assembly is then pulled out. When the upper pressure roller assembly 4 and the lower pressure roller assembly 5 are pushed back, the upper pressure roller assembly 4 and the lower pressure roller assembly 5 gradually approach the cleaning soft brush 306. When the upper pressure roller assembly 4 and the lower pressure roller assembly 5 reach the upper and lower sides of the cleaning soft brush 306 respectively, the cleaning soft brush 306 slides inside the guide slide groove 310 through the guide slider 307, while the reset telescopic rod 308 and the reset spring 309 extend and retract simultaneously, so that the bristles of the cleaning soft brush 306 are in close contact with the upper pressure roller assembly 4 and the lower pressure roller assembly 5 respectively. At the same time, the lubricating oil in the lubricating oil tank 301 can flow to the oil outlet plate 303 through the oil supply pipe 302 and be sprayed out by the oil outlet nozzle 304 to lubricate the upper pressure roller assembly 4 and the lower pressure roller assembly 5. When the upper pressure roller assembly 4 and the lower pressure roller assembly 5 are pushed back, the cleaning soft brush 306 can move on the upper pressure roller body 401 and the lower pressure roller body 502, thereby applying the lubricating oil to the surface of the upper pressure roller body 401 and the lower pressure roller body 502.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
