separate from the blocking block 211, at this time, the outer rotary drum 21 will stop rotating to protect the corner from being torn, then the first elastic folding part 232 will contract to make the barb 231 be hooked on another blocking block 211 quickly, so as to prevent the corner from losing the tightening effect due to the inversion of the outer rotary drum 21, and when the barb 231 is hooked on another blocking block 211, the outer rotary drum 21 can be driven to rotate continuously to maintain the normal operation of winding operation, the pushing and supporting columns 24 can be held by hand to slide along the inner wall of the inner rotary cylinder 22, the resistance balls 23 can extend out of the ball holes 221 along with the sliding of the pushing and supporting columns 24, so that the resistance balls 23 extend out of the inner rotary cylinder 22 to be attached to the blocking blocks 211, the number of the resistance balls 23 is increased to adjust resistance and correspond to corners with different diameters, the inner rotary cylinder 22 and the central shaft 34 are connected through the universal cross coupling 35, the inner rotary cylinder 22 can be arranged obliquely to the central shaft 34, so that the corners and finished products are distinguished at a certain angle, and the corners on the outer rotary cylinder 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 the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and are not to be construed as limiting the scope of the invention.
