magnetic conduction semi-ring 51, and when the central shaft 34 rotates along with the inner cylinder 22 in normal rotation, the barb 231 can be hooked on the blocking block 211, to pull the outer drum 21 to rotate normally and wind up the corners, and the magnetically conductive half ring 51 rotates along with the rotation of the inner drum 22, at this time, the magnetically conductive half ring 51 will adsorb the arc-shaped attaching surface 521 to drive the turning rod 52 to turn over and push the guiding rod 53 to turn over, so that the guiding arc 531 moves and bends the corners and waves, so that the corners will not taper when collected onto the outer drum 21, and when the inner drum 22 rotates at too high speed, the corners will be too tight to generate force to pull the outer drum 21, at this time, the barbs 231 will be extruded and deformed to disengage from the blocking pieces 211, at this time, the outer drum 21 stops rotating to prevent the corners from breaking, then the first elastic folding portion 232 will shrink to allow the barbs 231 to be hooked on the other blocking piece 211 quickly, so as to prevent the corners from losing the tight effect caused by the inversion of the outer drum 21, the hook 231 can also continuously drive the outer drum 21 to rotate to maintain the normal operation of winding operation when being hooked on the other blocking piece 211, the pushing and supporting column 24 can be held by hand to slide along the inner wall of the inner drum 22, along with the sliding of the pushing and supporting column 24, the resistance balls 23 can extend out of the ball holes 221, so that the resistance balls 23 extend out of the inner drum 22 to be attached to the blocking piece 211, the number of the resistance balls 23 is increased, the resistance can be adjusted, corners with different diameters can be corresponding, the inner drum 22 and the central shaft 34 are connected through the cross universal coupling 35, the inner drum 22 can be inclined to the central shaft 34, and a certain angle is formed between the corners and finished products, so that the corners on the outer drum 21 and the finished products on the main winding roller 1 can be recovered.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention.
