[0047] The implementation principle of a steel coil uncoiler provided in an embodiment of the present application is: in the initial state, the movable seat 12 is located in the loading area 122, the control block 42 is in contact with the inner wall of the abutment slide 411, the supporting portion 31 and the support block 2 are located at the position closest to the base 1, and the steel coil is moved to the support block 2 through a transfer tool. During this process, the two support rollers 21 located on the support block 2 cooperate to adjust the position of the steel coil, and the initial loading is completed.

[0048] The movable seat 12 is pushed to slide from the loading area 122 to the supporting area 123. The end of the control part 6 with the control slope 63 is first inserted into the matching slide 62 and put into place. At this time, the ball 222, under the action of the positioning spring 223, pushes the display block 125 to slide until the display block 125 is partially located outside the positioning groove 124. The support motor is started, so that the support part 31 drives the support block 2 to slide away from the base 1 under the action of the threaded transmission until the hollow part of the steel coil is located outside the placement groove 13. At this time, the positioning column 22 slides until the ball 222 is received in the positioning slide 221. After the steel coil bearing is inserted into the hollow part of the steel coil, the support motor is started again to control the support block 2 to slide until the steel coil bearing is in contact with the inner wall of the placement groove 13.

[0049] The steel coil is unwound and moved to cooperate with the guide roller assembly 14 and the pressure roller 151, and then the operator turns the control button 431 located outside the abutment block 4, so that the control block 42 first slides to the abutment wheel 412 on the abutment portion 41 under the action of the threaded transmission and fits the outer wall of the steel coil, and then continues to turn the control button 431, so that the abutment portion 41 slides toward the control block 42 and compresses the abutment spring 423; in this process, the control gear 64 can rotate under the cooperation of the synchronous toothed belt 641 and the control gear 432, so that the control part 6 slides along the cooperating slide groove 62 under the action of the threaded transmission to the locking block 5 and embeds into the locking groove 52, locking the sliding of the moving seat 12, and then the placement motor 152 can be started to unwind the steel coil.

[0050] When disassembling, the steel coil bearing must be removed first, and then the support block 2 is moved to the position closest to the base 1.
