It should be noted that the cam shaft 50 described herein should be identical to the cam, or any other variant of the cam, as long as they fulfill the same function, i.e., the function of driving the rotation of the clamp plate.

Referring to fig. 6 and 7, the rotation of the cam shaft 50 can push the clamp plate 60 to rotate, so as to separate the side wall of the clamp plate 60 from the side wall of the groove 201, thereby forming a gap with an angle t between the side wall of the clamp plate 60 and the side wall of the groove 201, so that after the start end of the coiled material is fed into the gap, the cam shaft 50 rotates reversely, thereby driving the clamp plate 60 to rotate reversely, so that the side wall of the clamp plate 60 and the side wall of the groove 201 abut against each other, and the gap disappears, thereby achieving the purpose of tightening the start end of the coiled material.

Compared with the prior art, the utility model discloses an in the technique, splint 60 and recess 201 are not independent separation, do not have splint 60 and need strictly align with recess 201, then splint 60 translation embedding recess 201 is with the tight principle requirement of the initiating terminal clamp with the coiled material in the recess 201, the technical scheme of the utility model, only need camshaft 50 drive splint 60 at the recess 201 internal rotation, make splint 60 lateral wall and recess 201 lateral wall offset or the separation can. Therefore, the section of the clamping plate 60 can be smaller than that of the groove 201 during design, so that a certain space can be provided for the clamping plate 60 to rotate after the clamping plate 60 is installed in the groove 201, and the aim of abutting or separating the side wall of the clamping plate 60 and the side wall of the groove 201 is fulfilled. In another embodiment, the following design is also possible:

the axial direction of the clamping plate 60 is provided with a receiving groove 601, and the cam shaft 50 is positioned in the receiving groove 601. The receiving groove 601 is axially opened, and the opening direction can be opposite to the rotating shaft body 20. When the cam shaft 50 pushes against the inner wall of the receiving groove 601 of the clip 60, the side wall of the clip 60 is separated from the side wall of the groove 201, forming a gap. After the start of the web enters the nip, the cam shaft 50 is rotated in the reverse direction so that the cam shaft 50 presses against the inner wall of the receiving groove 601 in the reverse direction, thereby abutting the side wall of the clamping plate 60 against the side wall of the groove 201 and clamping the start of the web.

In order to make the structure more compact, a notch with an acute section can be arranged in the axial direction of the rotating shaft body 20 as the groove 201, and the section of the clamping plate 60 is matched with the acute notch, wherein the two end faces of the groove 201 are provided with the mounting side walls 202, the two rotating pin shafts 40 are respectively and relatively rotatably mounted on the two mounting side walls 202, and the two ends of the clamping plate 60 are respectively fixed on the two rotating pin shafts 40.
