On the basis of the above embodiment, the side positioning assembly 14 is provided on one side of the first positioning assembly 11 and the second positioning assembly 12, and the side positioning assembly 14 includes two clamping members 141 disposed opposite to each other. Two sandwiching pieces 141 are provided on one side in the radial direction of the driving registration roller 111 and the driven registration roller 121, respectively. The clamping members 141 are telescopic cylinders, and the cylinder is adopted as the clamping members 141 in the scheme, wherein one clamping member 141 is arranged on the outer side of the side wall of the first positioning frame 112, and the side wall is a side wall without a motor for driving the active positioning roller 111. The other clamping member 141 is provided on the side of the positioning base 1221 remote from the positioning side plate 121. The movable end of each clamping piece 141 is provided with a clamping block 142, and one side of the clamping block 142 corresponding to the two clamping pieces 141 opposite to each other is provided with a notch. The clamp 141 mainly serves to position the web initially. Because the driving registration roller 111 and the driven registration roller 121 are both in contact with the web, the positioning of the web is not good until the two are brought together. The first positioning assembly 11 and the second positioning assembly 12 are separated prior to the web being placed into the present mechanism. When the coil is put into the mechanism, the two clamping members 141 are firstly operated, namely the clamping members 141 are stretched, the two clamping blocks 142 are close, and one end of the coil is firstly clamped through the clamping blocks 142.
