Description

Technical Field

[0001] The utility model relates to the technical field of unwinding restraint devices, in particular to an unwinding restraint system. Background Art

[0002] The basic components of the unwinding device usually include an unwinder, a tension control device, a deviation correction device, etc. Among them, the unwinder is the core part of the unwinding device, which is usually composed of a frame, a reel, a transmission device, etc. The tension control device is used to control the tension during the unwinding process to ensure the stability and flatness of the material during the transportation process.

[0025] The specific usage scenario of this embodiment is: by setting an adaptive support component to support the bottom of the steel coil 350 without affecting the rotation and unwinding of the steel coil 350, by setting an unwinding constraint component to achieve a good constraint effect between the top and bottom outer walls of the steel coil 350.

[0030] Example 4: Figure 5The unwinding constraint assembly includes a side plate 400, two side plates 400 are provided, the side plate 400 is fixedly mounted on the outer wall of the top of the workbench 100, the outer wall of the side plate 400 is rotatably connected to the rotating platform 410, the bottom of the rotating platform 410 and the top of the workbench 100 are rotatably connected to the second cylinder 430 through a movable block, the rear end inner wall of the rotating platform 410 is fixedly mounted with a conveyor belt 420, the inner wall of the side plate 400 is rotatably connected to the unwinding limit frame 440 through a rotating shaft, and the top outer wall of the side plate 400 is fixedly mounted with a top Plate 401, a lifting plate 441 is fixedly installed at the bottom of the unwinding limit frame 440, the top plate 401 and the lifting plate 441 are rotatably connected to the third cylinder 442 through a movable block, the second servo motor 450 is fixedly installed on the top outer wall of the unwinding limit frame 440, the bottom outer wall of the unwinding limit frame 440 is rotatably connected to the unwinding roller 461 through the second bearing seat 460, and the end of the unwinding roller 461 and the outer wall of the output shaft of the second servo motor 450 are connected through the second pulley 451 and the second belt 452.

[0031] The specific usage scenario of this embodiment is: by controlling the third cylinder 442 to pull the unwinding limit frame 440 at the same time, the unwinding limit frame 440 can be rotated, so that the unwinding roller 461 at the bottom of the unwinding limit frame 440 pressurizes the top unwinding point of the steel coil 350.

[0032] The working principle of the utility model is as follows: when in use, a person skilled in the art installs the steel coil 350 to be unwound on the outer wall of the unwinding shaft 340, hoists the unwinding shaft 340 and the steel coil 350 so that the unwinding shaft 340 can be placed on the top of the two rotating rollers 221 for support, controls the first cylinder 210 to lift and lower and adjusts the position of the unwinding shaft 340 and the steel coil 350 on the driving wheel at the bottom of the base 200, so that one end of the unwinding shaft 340 is aligned with the top outer wall of the lifting frame 310. The other end is plugged into the hexagonal prism 361 on the outer wall of the driving shaft 330, and then the second cylinder 430 is driven to control and adjust the rotation angle of the rotating platform 410 and the conveyor belt 420 around the inner wall of the side plate 400, so that the rotating platform 410 and the conveyor belt 420 support the bottom of the starting end of the steel sheet, so that the steel coil 350 can be unrolled, and at the same time, the unwinding limit frame 440 is pulled by controlling the third cylinder 442 so that the unwinding limit frame 440 can rotate, so that The unwinding roller 461 at the bottom of the unwinding limit frame 440 applies pressure to the unwinding position at the top of the steel coil 350, and then the first servo motor 360 is turned on to drive the driving shaft 330 and the unwinding shaft 340 to rotate. Under the limiting action of the unwinding roller 461 and the rotating roller 221, the steel coil 350 is unwound as the unwinding roller 461 rotates. Since the rotating roller 221 and the bottom of the steel coil 350 are in rolling friction, the friction force on the surface of the steel coil 350 is greatly reduced, thereby To prevent the surface of the steel coil 350 from being worn by powder, the second servo motor 450 is turned on to drive the unwinding roller 461 to squeeze and limit the top of the steel coil 350. When the unwinding shaft 340 rotates, the height of the rotating roller 221 can be continuously adjusted. By adjusting the rotating platform 410 and the unwinding limit frame 440, the height changes with the diameter of the steel coil 350, thereby facilitating the whole process of constraining the surface of the steel coil 350 and unwinding the steel coil 350 quickly and smoothly.
