Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, in particular to a large lead plate rolling mill. Background Art

[0002] Lead plate refers to a plate rolled from metal lead. It has strong corrosion resistance and acid and alkali resistance. It is also a relatively cheap radiation protection material in many aspects such as construction in acid-resistant environments, medical radiation protection, X-rays, CT room radiation protection, weighting, sound insulation, etc.

[0003] During the production and processing of existing lead sheets, a rolling mill is required to press the lead sheets. During the rolling process, two rollers apply pressure to the lead sheets. However, during the actual pressing process, granular impurities are present on the lead sheets. Current rolling mills are not equipped to clean these impurities, so the particles easily adhere to the rollers. Prolonged adhesion and repeated rolling can easily damage the rollers, shortening their service life. Therefore, we propose a large-scale lead sheet rolling mill. Utility Model Content

[0004] The purpose of the utility model is to provide a large-scale lead plate rolling mill, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a large-scale lead plate rolling mill, comprising a fixed frame, a driving roller rotatably mounted on the lower side of the inner cavity of the fixed frame, a servo motor fixed to one side wall of the fixed frame, a drive shaft of the servo motor movably passing through the fixed frame and fixedly connected to one end of the driving roller;

[0006] The two side walls of the fixed frame are provided with strip holes, and adaptive sliding blocks are provided in the two strip holes. The inner cavity of the fixed frame is provided with movable rollers, and the two ends of the movable rollers are rotatably connected to the two inner side walls of the sliding blocks. A connecting frame is provided on the upper side of the inner cavity of the fixed frame, and the two ends of the connecting frame are fixedly connected to the outer walls of the two sliding blocks. A hydraulic cylinder is fixed at the middle of the top of the fixed frame, and the push rod of the hydraulic cylinder movably passes through the fixed frame and is connected to the connecting frame. A fixed shell is fixed to the two side walls of the fixed frame, and a plurality of evenly distributed rollers are rotatably installed in the inner cavity of the fixed shell. A purge assembly is installed near the fixed frame at the inner cavity of one of the fixed shells, and brush plates are fixed on the upper and lower sides of one side wall of the purge assembly, and bristles are fixed on the side walls of the upper and lower two brush plates close to each other.

[0007] By adopting the above technical solution, the lead plate is placed on the roller shaft on one side for movement, then passes through the brush plate and the purge assembly, and then enters between the movable roller and the active roller. The hydraulic cylinder drives the connecting frame and the movable roller to descend to apply pressure to the lead plate, and the servo motor drives the active roller to rotate, thereby driving the lead plate to move under pressure, thereby realizing the rolling of the lead plate. Before the lead plate enters the rolling, the bristles can be used to brush the upper and lower surfaces of the lead plate to brush off the adhered impurity particles, and the purge assembly can be used to blow again to improve the cleaning effect, which is beneficial to avoid the influence of impurities on the active roller and the movable roller, thereby protecting the active roller and the movable roller.

[0008] As a preferred embodiment of the present invention, the purge assembly includes a hollow frame and an air pump, the hollow frame is fixed to the inner cavity of the fixed shell, the air pump is fixed to the side wall of the fixed shell, the output end of the air pump is connected to the hollow frame through a conduit, and the top and bottom of the hollow frame are provided with inclined air holes.

[0009] By adopting the above technical solution, gas is generated by an air pump to form a hollow frame, and then blown toward the upper and lower surfaces of the lead plate along the inclined air holes, so that the impurities remaining on the surface of the lead plate after the bristles are brushed off can be blown away, thereby improving the cleaning effect and helping to further avoid the influence of impurity particles on the active roller and the movable roller.

[0010] As a preferred embodiment of the present invention, a pressure sensor is fixedly installed on the top of the connecting frame, and the outer end of the push rod of the hydraulic cylinder is fixedly connected to the pressure sensor.

[0011] By adopting the above technical solution, the hydraulic cylinder pushes the connecting frame down so that the movable roller can monitor the pressure when initially applying pressure to the lead plate, thereby ensuring accurate pressure and further ensuring the effect of rolling the lead plate.

[0012] As a preferred embodiment of the present invention, both side walls of the inner cavity of the strip-shaped hole are provided with limiting grooves, and the inner cavity of the limiting groove is plugged with an adaptive limiting slider, and the outer wall of the limiting slider is fixedly connected to the side wall of the sliding block.

[0013] By adopting the above technical solution and setting the limiting slider, the stability of the sliding block in lifting and lowering can be further improved.

[0014] As a preferred embodiment of the present invention, limiting rods are fixed on both sides of the top of the connecting frame, and the limiting rods movably pass through the fixing frame.

[0015] By adopting the above technical solution and setting the limit rod, the hydraulic cylinder drives the connection frame to rise and fall with high stability.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The technical solution of the present application is a large-scale lead plate rolling mill, in which bristles on upper and lower brush plates can be used to brush the upper and lower surfaces of the lead plates, thereby brushing off foreign particles, thereby preventing the particles from adhering to the active rollers and the movable rollers when the active rollers and the movable rollers are rolling the lead plates, thereby facilitating the avoidance of damage to the active rollers and the movable rollers, and extending the service life of the active rollers and the movable rollers;

[0018] The air pump generates gas to hollow the frame, and then blows it toward the upper and lower surfaces of the lead plate along the inclined air holes, thereby blowing away the impurities remaining on the surface of the lead plate after being brushed off by the bristles, improving the cleaning effect and further preventing the impurity particles from affecting the active roller and the movable roller;

[0019] The hydraulic cylinder pushes the connecting frame down so that the movable roller can monitor the pressure when initially applying pressure to the lead plate, thereby ensuring accurate pressure application and further ensuring the effect of rolling the lead plate.

[0028] Both side walls of the fixed frame 1 are provided with strip holes, and adaptive sliding blocks 14 are provided in the two strip holes. The inner cavity of the fixed frame 1 is provided with a movable roller 13, and the two ends of the movable roller 13 are rotatably connected to the inner side walls of the two sliding blocks 14 respectively.

A hydraulic cylinder 16 is fixed at the top middle of the fixed frame 1, and the push rod of the hydraulic cylinder 16 moves through the fixed frame 1 and is connected to the connecting frame 15. A fixed shell 2 is fixed to both side walls of the fixed frame 1, and a plurality of uniformly distributed rollers 21 are rotatably installed in the inner cavity of the fixed shell 2. A purge assembly is installed near the fixed frame 1 at the inner cavity of one of the fixed shells 2, and a brush plate 25 is fixed on the upper and lower sides of one side wall of the purge assembly, and a brush bristle 22 is fixed on the side wall where the upper and lower brush plates 25 are close to each other;

[0029] In actual use, the lead plate is placed on the roller shaft 21 on one side and moved, then passes through the brush plate 25 and the purge assembly, and then enters between the movable roller 13 and the active roller 11. The hydraulic cylinder 16 drives the connecting frame 15 and the movable roller 13 to descend to apply pressure to the lead plate, and the servo motor 12 drives the active roller 11 to rotate, thereby driving the lead plate to move under pressure, thereby realizing the rolling of the lead plate. Before the lead plate enters the rolling, the bristles 22 can be used to brush the upper and lower surfaces of the lead plate to brush off the adhered impurity particles, and using the purge assembly to blow again can improve the cleaning effect, which is beneficial to avoid impurities from affecting the active roller 11 and the movable roller 13, thereby protecting the active roller 11 and the movable roller 13.

[0030] Furthermore, limiting rods 18 are fixed on both sides of the top of the connecting frame 15. The limiting rods 18 are movable and penetrate the fixed frame 1. The setting of the limiting rods 18 enables the hydraulic cylinder 16 to drive the connecting frame 15 to move up and down with high stability.

[0031] Furthermore, limiting grooves are provided on both side walls of the inner cavity of the strip hole, and an adaptive limiting slider is inserted into the inner cavity of the limiting groove. The outer wall of the limiting slider is fixedly connected to the side wall of the sliding block 14.

[0032] like Figure 1 and 3 As shown; the purge assembly includes a hollow frame 23 and an air pump 24, the hollow frame 23 is fixed to the inner cavity of the fixed shell 2, the air pump 24 is fixed to the side wall of the fixed shell 2, the output end of the air pump 24 is connected to the hollow frame 23 through a conduit, and the top and bottom of the hollow frame 23 are provided with inclined air holes 26;

[0033] The air pump 24 generates gas to the hollow frame 23, and then blows it toward the upper and lower surfaces of the lead plate along the inclined air holes 26, so that the impurities remaining on the surface of the lead plate after being brushed off by the bristles 22 can be blown away, thereby improving the cleaning effect and helping to further prevent the impurity particles from affecting the active roller 11 and the movable roller 13.

[0035] The hydraulic cylinder 16 pushes the connecting frame 15 downward so that the movable roller 13 can monitor the pressure when initially applying pressure to the lead plate, thereby ensuring accurate pressure application and further ensuring the effect of rolling the lead plate.

[0036] The implementation principle of a large lead plate rolling mill of the present application is as follows: in actual use, the lead plate is placed on the roller shaft 21 on one side for movement, then passes through the brush plate 25 and the purge assembly, and then enters between the movable roller 13 and the active roller 11, and the hydraulic cylinder 16 drives the connecting frame 15 and the movable roller 13 to descend to apply pressure to the lead plate. When the lead plate is initially pressurized, the pressure sensor 17 can be used to monitor the pressure to ensure accurate pressure application, and the servo motor 12 drives the active roller 11 to rotate, thereby driving the lead plate to move under pressure, thereby To achieve the rolling of the lead plate, before the lead plate enters the rolling process, the bristles 22 can be used to brush the upper and lower surfaces of the lead plate to brush off the adhering impurity particles, and the air pump 24 generates gas to form a hollow frame 23, and then blows it toward the upper and lower surfaces of the lead plate along the inclined air holes 26, so that the impurities remaining on the surface of the lead plate after being brushed off by the bristles 22 can be blown away, thereby improving the cleaning effect and helping to further avoid the influence of impurity particles on the active roller 11 and the movable roller 13, thereby protecting the active roller 11 and the movable roller 13.
