The adjusting device 2 includes a rotating rod 201. One end of the rotating rod 201 is rotatably connected to the side surface of the protective shell 102, and the other end of the rotating rod 201 is fixedly connected to a turntable 202. A motor 203 is fixedly connected to the side surface of the turntable 202. The output shaft of the motor 203 is fixedly connected to a reciprocating lead screw 204. A threaded block 205 is threadedly connected to the circumferential surface of the reciprocating lead screw 204. A fixed block 207 is fixedly connected to the circumferential surface of the threaded block 205. A rotating rod 208 is rotatably connected to the side surface of the fixed block 207. One end of the rotating rod 208 away from the fixed block 207 is rotatably connected to a positioning block 209. An installation block 210 is fixedly connected to the top of the positioning block 209. A positioning rod 211 is fixedly connected to the side surface of the installation block 210. One end of the positioning rod 211 away from the installation block 210 is fixedly connected to a slider 212. A disc 213 is arranged on the side surface of the slider 212. A chute 214 is opened on the side surface of the disc 213. The inner wall of the chute 214 is slidably connected to the side surface of the slider 212. A limiting rod 206 penetrates through the side surface of the threaded block 205. It can be applicable to steel coils with different inner diameters. By adjusting and moving components such as the positioning rod 211 and the installation block 210, effective tightening and positioning of the take-up drums with different sizes can be achieved, enabling the equipment to flexibly respond to the production requirements of different specifications and sizes, improving the versatility and adaptability of the production line, ensuring the stability and reliability of the take-up drum during operation, and avoiding production interruptions or quality problems caused by poor positioning.

[0029] In this embodiment, the motor 203 is driven to rotate the reciprocating lead screw 204, and then the reciprocating lead screw 204 rotates to drive the threaded block 205 to perform a horizontal displacement. The threaded block 205 is limited by the limiting rod 206 on the side surface of the threaded block 205. Then, the displacement of the threaded block 205 drives the fixed block 207 to displace. The displacement of the fixed block 207 drives the rotating rod 208 to rotate. Then, the rotation of the rotating rod 208 causes the other end of the rotating rod 208 to move upward, causing the positioning block 209 to move upward. Then, the upward movement of the positioning block 209 drives the installation block 210 to move upward. The displacement of the installation block 210 drives the positioning rod 211 to move upward. The positioning rod 211 drives the slider 212 to displace along the chute 214, achieving the effect that the four positioning rods 211 can tighten take-up drums with different inner diameters, and it is applicable to steel coils with different inner diameters.

The material of the airbag 215 is set to be rubber. The number of the positioning rods 211 is set to be several and is arranged in a circumferential array on the side of the threaded block 205. The fixing frame 104 is fixedly connected to the top of the protective shell 102. One end of the limiting rod 206 is fixedly connected to the side of the turntable 202. The number of the positioning blocks 209 is set to be several, two in a group, and is arranged in a circumferential array on the side of the threaded block 205. The airbag 215 is located on the movement track of the slider 212. The size of the turntable 202 is the same as that of the disc 213. The airbag 215 is used to push the slider 212 to displace, and the power is transmitted to the cleaning roller 222 through a complex transmission device, realizing the cleaning effect on the surface of the steel coil. This kind of cleaning can effectively remove the dirt, oxide layer or other bad substances on the surface, improving the surface quality and smoothness of the steel coil. The design of the cleaning roller 222 can usually ensure the gentle treatment of the surface of the steel coil, avoiding damage caused by excessive friction or improper cleaning.

[0032] In this embodiment, the airbag 215 is extruded by the displacement of the slider 212, so that the gas inside the airbag 215 is pushed into the air pressure chamber 216, causing the sliding rod 217 to displace. The displacement of the sliding rod 217 drives the rack 218 to displace, and then the displacement of the rack 218 drives the gear 220 to rotate. The rotation of the gear 220 drives the rotating shaft 221 to rotate, and then the rotation of the rotating shaft 221 drives the cleaning roller 222 to rotate, realizing the effect of cleaning the surface of the steel coil and improving the quality of the steel coil.
