Push block 304b and folding rod 304d can be assembled on the second slide table 304a, and the bending part of folding rod 304d is hinged with the end of the second sliding table 304a, so folding rod 304d can rotate with the bending part as the center of circle. 8, the hinged rod 304c is hinged with the bottom of the folding rod 304d and the left end of the push block 304b at the same time. Between the push block 304b and the second sliding platform 304a there is a limit groove 304a-1 for limit. The length of the limit groove 304a-1 is prioritized to prevent the push block 304b from moving excessively. The push block 304b can move linearly along the direction of the limit groove 304a-1. When the push block 304b moves to the left, the hinge rod 304c pushes the folding rod 304d to rotate. When the push block 304b moves to the limit groove 304a-1 At the limit, the folding rod 304d is in a vertical state, and the push spring 304a-2 pushes the push block 304b to move after the release rod 304d-2 breaks away from the release hole 301g. The threaded ring 304a-3 is at the bottom of the second sliding table 304a, with a threaded hole in the center, which can cooperate with the screw mandrel 306. When the second servo motor 305 drags the screw mandrel 306 to rotate, the second sliding table 304a moves along the first The slide table 303b moves in a linear direction.

When in use, put the steel strip coil on the supporting rod 103e, move the sliding table 103a to a suitable distance and lock it with the latch 103c, then tilt the steel strip coil to a suitable angle through the second hydraulic rod 103f, and adjust the supporting shell 102 To the appropriate height of the pallet 101a, to meet the placement of steel coils of different diameters, the support shell 102 is adjusted to an angle that can be aligned with the center of the steel coils by the first hydraulic rod 104. At this time, the output rod 202c and the steel coils center on the same axis, and then start the first servo motor 201 to drive the multi-section rod 205 to move to the right through the worm disk 203. During the continuous movement, the pressure plate 301c is pressed and moves leftward compared to the moving direction of the multi-section rod 205. At this time, the compression spring 301b is pressed and compressed, and the traction block 301a is driven to move to the left relative to the multi-section rod 205. At this time, The three support blocks 302 are pushed outward by the conical block 301f until the traction block 301a stops moving after the inner side of the steel strip coil is pressed, and the first servo motor 201 also stops running. At the same time, the release lever 304d-2 disengages and releases hole 301g, and after the folded rod 304d crosses the inner ring of the steel strip coil under the drive of the multi-section rod 205, the push spring 304a-2 that has been in compression can push the push block 304b at this time, and the push block 304b will be moved by the hinge rod 304c The folding rod 304d is pushed to the erection, and will not be excessively advanced due to the effect of the limiting groove 304a-1 after the erection. Finally, the second servo motor 305 is running, and the second sliding table 304a can be pushed to the other side of the steel strip coil through the screw rod 306, and then the first hydraulic lever 104 is adjusted to lift the clamping unit 300 together with the steel strip coil. Work, the steel strip coil is clamped and the center is supported at this time. It should be noted that replacing the push spring 304a-2 with an electric push rod has a better clamping and fixing effect.

When dismantling, just remove the locking bolt 303a and remove the bearing sleeve 303 directly.
