[0029] Specifically, a guide seat 304 is installed on the surface of one side of the two internal thread plates 303 , and a guide plate 305 is fixedly connected to the inner side of the guide seat 304 .

[0030] In a specific embodiment of the present invention, the paper web can be guided by the coordinated use of the guide seat 304 and the guide plate 305, thereby reducing the probability of wrinkles on the paper web.
