When it comes into contact with the cold rolling rolls, it will adhere to the processing rolls. During rolling, this will cause scratches on the surface of the workpiece and affect the rolling quality of the workpiece. Utility Model Content

[0008] The cleaning unit on the adjusting mechanism and the cold rolling mill stand includes a mounting base, which is installed on the adjusting mechanism and the cold rolling mill stand. The mounting base is equipped with a first connecting valve and a dust suction hole. The mounting base has a receiving cavity inside. A slide rod is slidably installed on the mounting base. An elastic component is installed at the end of the slide rod located in the receiving cavity. A scraper is installed at the other end of the slide rod. The scraper is slidably connected to the first cold rolling roll and the second cold rolling roll. The dust suction hole is connected to the first connecting valve and corresponds to the first cold rolling roll and the second cold rolling roll.
[0009] Furthermore, the elastic components on the mounting base include a spring and a top plate. The spring is installed inside the receiving cavity, and the top plate is installed on the portion of the slide rod located inside the receiving cavity. The top plate is connected to the spring.
[0010] Furthermore, an air jet port and a second connecting valve are provided at the end of the mounting base away from the dust suction hole. The air jet port and the dust suction hole are located on both sides of the scraper. The air jet port is connected to the second connecting valve and corresponds to the first cold rolling roll and the second cold rolling roll.
[0011] Furthermore, a cleaning unit for cleaning workpieces is installed on the cold rolling mill stand. The cleaning unit includes a fixing plate, which is installed on the cold rolling mill stand.

[0029] like Figures 1-8 As shown, a cold rolling mill for producing copper-magnesium alloy rods includes a cold rolling mill stand 1. Guide mechanisms 9 for guiding the cold-rolled workpieces are rotatably mounted at both ends of the cold rolling mill stand 1. An adjusting mechanism 6 and a first drive mechanism 2 are mounted on the cold rolling mill stand 1. A second cold rolling roll 8 for the cold-rolled workpiece is rotatably mounted on the cold rolling mill stand 1, and the second cold rolling roll 8 is connected to the power output end of the first drive mechanism 2. A second drive mechanism 12 is mounted on the adjusting mechanism 6, and a first cold rolling roll 7 for the cold-rolled workpiece is rotatably mounted on the adjusting mechanism 6. A cleaning unit for processing the first cold rolling roll 7 and the second cold rolling roll 8 is mounted on the adjusting mechanism 6 and the cold rolling mill stand 1. The first cold rolling roll 7 is connected to the power output end of the second drive mechanism 12. The first drive mechanism 2 and the second drive mechanism 12 are electrically connected to an external controller. The guide mechanism 9, adjusting mechanism 6, first drive mechanism 2, and second drive mechanism 12 are operational. Using existing technology, based on the dimensions of the workpiece before and after cold rolling, the distance between the first cold rolling roll 7 and the second cold rolling roll 8 is adjusted by the adjusting mechanism 6. During the cold rolling process, the workpiece is guided by the guiding mechanism 9 so that it enters between the first cold rolling roll 7 and the second cold rolling roll 8. The second cold rolling roll 8 is driven to rotate by the first driving mechanism 2, and the first cold rolling roll 7 is driven to rotate by the second driving mechanism 12. The workpiece is processed by the first cold rolling roll 7 and the second cold rolling roll 8 to complete the cold rolling. The cold-rolled workpiece is discharged and collected by the guiding mechanism 9. During cold rolling, the contact points between the workpiece and the first cold rolling roll 7 and the second cold rolling roll 8 need to be sprayed by an external spraying device. During the cold rolling process, the impurities adhering to the first cold rolling roll 7 and the second cold rolling roll 8 are treated by the cleaning unit to avoid impurities affecting the cold rolling quality of the workpiece.
[0030] like Figures 3-5As shown, the cleaning unit on the adjusting mechanism 6 and the cold rolling mill stand 1 includes a mounting base 301. The mounting base 301 is mounted on the adjusting mechanism 6 and the cold rolling mill stand 1. A first connecting valve 307 and a dust suction hole 308 are installed on the mounting base 301. A receiving cavity 302 is provided inside the mounting base 301. A slide rod 305 is slidably mounted on the mounting base 301. An elastic component is installed at the end of the slide rod 305 located in the receiving cavity 302. A scraper 306 is installed at the other end of the slide rod 305. The scraper 306 is slidably connected to the first cold rolling roll 7 and the second cold rolling roll 8. The dust suction hole 308 is connected to the first connecting valve 307. The cold rolling roll 7 and the second cold rolling roll 8 correspond to each other. The first connecting valve 307 is connected to the external dust collection device. The scraper 306 is attached to the first cold rolling roll 7 and the second cold rolling roll 8 through the elastic component. The scraper 306 causes the impurities to fall off the rotating first cold rolling roll 7 and the second cold rolling roll 8, avoiding the problem of impurities adhering to the first cold rolling roll 7 and the second cold rolling roll 8 and causing scratches on the surface of the cold rolled workpiece. This ensures the quality of cold rolling of the workpiece and improves the cold rolling effect. At the same time, the external dust collection device collects and processes the fallen impurities through the first connecting valve 307 and the dust collection hole 308, preventing impurities from falling onto the workpiece and affecting the cold rolling quality.
[0031] like Figure 5 As shown, the elastic components on the mounting base 301 include a spring 303 and a top plate 304. The spring 303 is installed in the receiving cavity 302, and the top plate 304 is installed on the portion of the slide rod 305 located in the receiving cavity 302. The top plate 304 is connected to the spring 303, and the spring 303 supports the slide rod 305 through the top plate 304, so that the scraper 306 can continuously adhere to the first cold rolling roll 7 and the second cold rolling roll 8, so that the scraper 306 can effectively treat the impurities on the first cold rolling roll 7 and the second cold rolling roll 8.
[0032] like Figures 3-5 As shown, an air jet 309 and a second connecting valve 310 are provided at the end of the mounting base 301 away from the dust suction hole 308. The air jet 309 and the dust suction hole 308 are located on both sides of the scraper 306. The air jet 309 is connected to the second connecting valve 310. The air jet 309 corresponds to the first cold rolling roll 7 and the second cold rolling roll 8. The second connecting valve 310 is connected to an external blower. During the cold rolling process of the workpiece, the external blower blows air onto the surfaces of the first cold rolling roll 7 and the second cold rolling roll 8 through the second connecting valve 310 and the air jet 309, causing impurities on the first cold rolling roll 7 and the second cold rolling roll 8 to be blown to both sides of the first cold rolling roll 7 and the second cold rolling roll 8, thus preventing impurities from falling onto the workpiece and affecting the quality of the cold rolling of the workpiece.
[0033] like Figure 2 , Figure 3As shown, a cleaning unit for cleaning workpieces is installed on the cold rolling mill stand 1. The cleaning unit includes a fixing plate 401, which is installed on the cold rolling mill stand 1. A screw 402 is threaded onto the fixing plate 401. A support base 403 is rotatably installed on the lower end of the screw 402. A steel brush mechanism 404 is installed on the support base 403. The steel brush mechanism 404 operates using existing technology. By rotating the screw 402, the support base 403 and the steel brush mechanism 404 are moved, adjusting their heights so that the steel brush mechanism 404 is in close contact with the cold-rolled workpiece. During cold rolling, the steel brush mechanism 404 cleans impurities from the surface of the cold-rolled workpiece, preventing impurities from adhering to the workpiece and affecting the cold-rolling quality of the workpiece.
[0034] like Figure 2 , Figure 3 As shown, a limit rod 405 is installed on the support base 403. The limit rod 405 is slidably connected to the fixing plate 401. The support base 403 drives the limit rod 405 to move, and the limit rod 405 limits the support base 403 to prevent it from tilting when moving.
[0035] like Figure 1 , Figure 2 , Figures 6-8 As shown, a limiting unit for preventing the cold-rolled material from deviating is installed on the cold rolling mill stand 1. The limiting unit includes a telescopic mechanism 501 and a limiting plate 502. The telescopic mechanism 501 is located on both sides of the cold rolling mill stand 1. The telescopic end of the telescopic mechanism 501 is slidably connected to the cold rolling mill stand 1. The limiting plate 502 is installed on the telescopic end of the telescopic mechanism 501. The limiting plates 502 on both sides of the cold rolling mill stand 1 are arranged opposite to each other. The telescopic mechanism 501 is electrically connected to an external controller. The telescopic mechanism 501 operates using existing technology. During the cold rolling process of the workpiece, according to the size of the workpiece after cold rolling, the telescopic mechanism 501 drives the limiting plate 502 to move, adjusting the distance between the limiting plates 502 on both sides of the cold rolling mill stand 1. The limiting plate 502 limits the cold-rolled workpiece to prevent the cold-rolled workpiece from deviating, thereby affecting the quality of the cold rolling.
[0036] like Figure 2 , Figure 7 As shown, a collection chamber 10 is provided at the lower end of the interior of the cold rolling mill stand 1. A liquid outlet pipe 11 is installed on the side of the cold rolling mill stand 1. The liquid outlet pipe 11 is connected to the collection chamber 10 and an external collection device. During cold rolling, coolant needs to be sprayed onto the cold rolling part of the workpiece by an external spraying device. The sprayed coolant falls into the collection chamber 10 for collection and is then discharged to the external collection device for recycling through the liquid outlet pipe 11.
[0037] Working principle: When cold rolling a workpiece, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, based on the dimensions of the workpiece before and after cold rolling, the distance between the first cold rolling roll 7 and the second cold rolling roll 8 is adjusted by the adjusting mechanism 6, as follows: Figure 2 , Figure 3 As shown, rotating the screw 402 causes the support base 403 and the steel brush mechanism 404 to move, adjusting the height of the support base 403 and the steel brush mechanism 404 so that the steel brush mechanism 404 can fit in close contact with the cold-rolled workpiece. When the support base 403 moves, it drives the limiting rod 405 to move, thus limiting the support base 403.
[0038] like Figures 1-3 , Figure 6 , Figure 7 As shown, the workpiece is guided by the material guiding mechanism 9 and enters between the first cold rolling roll 7 and the second cold rolling roll 8. The steel brush mechanism 404 cleans the impurities on the surface of the cold-rolled workpiece. The first drive mechanism 2 drives the second cold rolling roll 8 to rotate, and the second drive mechanism 12 drives the first cold rolling roll 7 to rotate. The workpiece is processed by the first cold rolling roll 7 and the second cold rolling roll 8 to complete the cold rolling of the workpiece. The cold-rolled workpiece is discharged and collected through the material guiding mechanism 9.
[0039] During cold rolling, such as Figures 3-5 As shown, spring 303 supports slide bar 305 via top plate 304, allowing scraper 306 to continuously adhere to the first cold rolling roll 7 and the second cold rolling roll 8. The scraper 306 causes impurities to fall off the rotating first cold rolling roll 7 and the second cold rolling roll 8. An external dust collection device collects the fallen impurities through first connecting valve 307 and dust collection hole 308. Simultaneously, an external blower device blows air onto the surfaces of the first cold rolling roll 7 and the second cold rolling roll 8 through second connecting valve 310 and air jet vent 309, blowing the impurities off the first cold rolling roll 7 and the second cold rolling roll 8 and directing them to the sides of the rolls, preventing impurities from falling onto the workpiece and affecting the quality of the cold rolling process.
[0040] like Figure 2 , Figure 7 As shown, when the workpiece is cold rolled, coolant is sprayed onto the cold-rolled part of the workpiece by an external spraying device. The sprayed coolant falls into the collection chamber 10 for collection and is then discharged into the external collection device through the outlet pipe 11 for recycling.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
