Technical Field

The invention relates to the technical field of splicing, in particular to a bobbin paper splicing method and a bobbin paper splicing system.

Background

Bobbin paper splicing refers to splicing the in-use bobbin paper and the standby bobbin paper together so as to meet the requirement of continuous production. In the existing cigarette making and splicing machine set, bobbin paper splicing adopts online dynamic lapping of double-sided adhesive tapes, and the double-sided adhesive tapes are moved to positions between double layers of bobbin paper to be spliced by utilizing a swing cylinder to rotate a swing arm. Because the bobbin paper is dynamically spliced, the running speed of the standby bobbin paper needs to be matched with the linear speed of the in-use bobbin paper.
