[0002] The aluminum cold rolling mill is a mechanical equipment specially used for cold rolling processing of aluminum alloy plates. Cold rolling is a process of rolling metal plate strips into thinner specifications by applying pressure to the metal material below the recrystallization temperature.

[0033] As shown in the accompanying Figure 1 to the accompanying Figure 4 :

[0034] This utility model provides an automatic tailing device and control system for an aluminum cold rolling mill, including a cold rolling assembly 101. Both ends of the cold rolling assembly 101 are provided with take-up and release assemblies 102. The take-up and release assemblies 102 at both ends of the cold rolling assembly 101 facilitate control of the material strip passing through the cold rolling assembly 101 for processing. The cold rolling assembly 101 includes a frame 10101, and tailing assemblies 103 are fixedly installed on both sides of the frame 10101. Each tailing assembly 103 includes a mounting frame 10301. Three guide rollers 10302 are rotatably connected to the top of the mounting frame 10301 near the end of the frame 10101. The guide rollers 10302 have two ends... A correction ring 10303 is fixedly installed on the side. Correction rings 10303 are also fixedly installed on the outer sides of both ends of the guide roller 10302. This facilitates the guide roller 10302 in guiding the strip into and out of the cold rolling assembly 101, preventing strip deviation during the tailing process. The diameter of the guide roller 10302 located in the middle is smaller than the diameter of the other two guide rollers 10302, and damping is provided between the middle guide roller 10302 and the mounting frame 10301. Damping is provided in the middle to facilitate the guidance of the material strip by the guide rollers 10302 at both ends during processing. During the tailing process, the damping at both ends of the middle guide roller 10302 decelerates and controls the material strip, reducing waste. Second telescopic rods 10304 are fixedly installed at both ends of the middle guide roller 10302, and lifting seats 10309 are fixedly installed at the output ends of the second telescopic rods 10304. The second telescopic rods 10304 and lifting seats 10309 are fixedly installed at the output ends of the second telescopic rods 10304, which facilitates the control of the lifting seats by the second telescopic rods 10304 during the tailing process. 10309 descends and performs automatic tail-swing. Shaft seats 10310 are fixedly installed at both ends of the bottom of the lifting seat 10309. Two clamping rollers 10311 are rotatably connected between the shaft seats 10310. The two clamping rollers 10311 are positioned at the top between the three guide rollers 10302. This arrangement of the two clamping rollers 10311 at the top between the three guide rollers 10302 facilitates the descent of the lifting seat 10309, causing the clamping rollers 10311 to tightly push the material belt against the outside of the middle guide roller 10302. This allows the middle guide roller 10302 to decelerate the material belt and provide tension, thereby stabilizing the tail-swing process and reducing waste generation.

[0035] The guide roller 10302 has clamping grooves 10305 at both ends, and the clamping grooves 10305 are located at the bottom of the shaft seat 10310. The clamping grooves 10305 at both ends of the guide roller 10302 and the clamping grooves 10305 are located at the bottom of the shaft seat 10310, which facilitates the lowering space of the shaft seat 10310 during automatic clamping and finishing.

The fixed connection between the output end of the receiving and releasing motor 10204 and the receiving and releasing roller 10203 facilitates the fixation of the material belt roll by the receiving and releasing roller 10203, and the receiving and releasing motor 10204 controls the winding and unwinding of the material belt roll.

[0039] The guide roller 10206 is rotatably connected to the top of the guide frame 10205, and tension sensors 10207 are fixedly installed at both ends of the guide roller 10206. The rotatable connection of the guide roller 10206 to the top of the guide frame 10205 and the fixed installation of the tension sensors 10207 at both ends of the guide roller 10206 facilitate the guidance of the material belt by the guide roller 10206 and the monitoring of the tension of the material belt during processing.
