The process design of production line rail tube feeding (Ping Wen). The uniaxial die shake head, in order to solve the problem of paper tube grip head smooth, uniform length and at the same time, one-time positioning line in the mouth, line clear and consistent in size, synchronous distance cut V shaped mouth. The biggest advantage is in the mechanical production of paper tube surface galling uniform, dear, to produce the paper tube can be beyond the quality of the appearance of Kang Feng production. The production process of paper tube quality and appearance can be the leading level at home and abroad, is a new century innovation.
