Description

Technical Field

[0002] The continuous production line of plates and strips has very high requirements for the unwinding process and tail swinging process. The fully automatic and accurate positioning of the head and tail of the strip must be completed in a very short time. Taking the galvanizing production line as an example, the maximum sleeve volume of the entrance loop is 480 meters, and the maximum process speed is 160 meters / minute. Therefore, the entrance section must complete the positioning and welding of the head and tail of the strip on the center line of the welding machine within 3 minutes to ensure the normal operation of the production line. Once the tracking and positioning of the head and tail of the strip deviates, manual intervention is required. It is impossible to complete the positioning welding process within 3 minutes, which will inevitably cause the production line to slow down and even stop running. Therefore, improving the tracking and positioning accuracy of the head and tail of the unwinding machine is an important part of the automation technology innovation of the plate and strip production line;

[0003] Therefore, a tracking and positioning device for the head and tail of the uncoiler is designed to optimize the above problems. Utility Model Content

[0022] General working principle: Before use, the mounting frame 5 is fixed to the inlet end of the slitting machine. The slitting machine is used to cut the waste at the head and tail of the tape. When in use, the coil is placed on the unwinder body 1, and then the coil is conveyed. At the same time, during the conveying process, the thickness of the coil is measured by the laser rangefinder 3, so as to determine the head and tail of the coil. After the coil is released from the unwinder body 1, it passes between the roller 6 and the pressure roller 8, and the conveying length of the coil is determined by the meter 10. The coil passes through the roller 6 then enters the interior of the slitting machine, the meter 10 calculates the conveying length, after reaching the set conveying length, the programmable controller 4 controls the slitting machine to cut the waste at the head of the belt, and then continues to convey the coil, after the coil is released, the reading of the laser rangefinder 3 does not change, at this time the distance between the unwinder body 1 and the mounting frame 5 is the remaining amount of the coil, and then, as the coil continues to be conveyed, after reaching the remaining waste length, the programmable controller 4 controls the slitting machine again to cut the waste at the tail of the belt.

[0023] In this embodiment, both ends of the mounting frame 5 are horizontally provided with protrusions, and the protrusions are provided with mounting holes.

[0024] Partial working principle: When fixing the mounting frame 5, the device is fixed by passing bolts through the mounting holes.

[0025] In this embodiment, the clamping mechanism 9 includes a guide groove 12, a slider 13 and a compression spring 15. The guide groove 12 is vertically opened on both sides of the mounting frame 5. The inside of the guide groove 12 is slidably provided with a slider 13. The two ends of the pressure roller 8 are respectively rotatably installed on the slider 13. A compression spring 15 is provided between the top of the slider 13 and the inner top of the guide groove 12.

[0026] Partial working principle: During the coil conveying process, the compression spring 15 continuously applies downward pressure to the pressure roller 8 to ensure that the pressure roller 8 presses the coil tightly and the conveying is more stable.

[0027] In this embodiment, a guide rod 14 is fixed between the upper and lower ends of the guide groove 12 . The guide rod 14 passes through the slider 13 and the compression spring 15 . The guide rod 14 is slidably connected to the slider 13 .

[0028] Partial working principle: During the sliding of the slider 13, the guide rod 14 is arranged to ensure that the slider 13 is in a vertical sliding state.

[0029] In this embodiment, the cleaning mechanism 11 includes a flip rod 16, a brush plate 17 and a tension spring 18. The flip rod 16 is hingedly mounted at the bottom of the mounting frame 5. The two groups of flip rods 16 are symmetrical to each other. A brush plate 17 is installed between the two groups of flip rods 16. A tension spring 18 is provided between the top of the flip rod 16 and the side of the mounting frame 5.

[0030] Partial working principle: During the coil conveying process, the brush plate 17 is attached to the bottom of the coil. When the coil is conveyed, friction occurs between the brush plate 17 and the coil, thereby self-cleaning the bottom surface of the coil to ensure the stable rotation of the roller 6.

[0031] In this embodiment, the brush plate 17 and the turning rod 16 are mutually engaged, and a groove is provided at the top of the turning rod 16 .

[0032] Partial working principle: After a long period of cleaning, the brush plate 17 needs to be replaced, and the clamping installation method is adopted to make the replacement of the brush plate 17 more convenient.
