Description

Technical Field

[0001] The present application relates to the technical field of paper processing, and in particular to a paper reel and a position-adjustable gluing device thereof. Background Art

[0002] High-speed white cardboard machines frequently experience abnormal triangular head adhesion when making various types of paper weights, resulting in poor base preparation during roll change, base deviation, paper breakage, and roll change failure. The bonding quality of the triangular head during roll change directly affects the output of the paper machine. When winding and changing rolls, the triangular head is cut off by a water needle, and then the glue spraying system sprays glue for bonding. After the triangular heads of different paper weights are cut out, the airflow formed by the auxiliary blowing device and the high rotation of the iron core roller is carried to the prepared iron core roller. During this period, the positions of the triangular heads of different paper weights will be displaced, resulting in the glue spraying not being able to stick to the triangular heads, which seriously affects the operating efficiency of the paper machine.
