∎ History and main structural units of
single corrugated laminating production line
Following are the technical advantages of SCL1650:
Higher production efficiency and lower labor cost: In
offset printing of single paper, the mounting efficiency is triple to the
traditional laminating machines. In the packaging machinery marker in pursuit
of high intelligence and automatic production, the production line perfectly
satisfies industrial demands for its low labor cost (only 4 operators needed).
It also replaces a single corrugated line (or three-layer line) and three
laminating machines, meaning that 10 operators can be saved.
Advanced gluing method and scatheless pre-printing: Given
the gluing mode with single corrugated board on top and pre-printing roll paper
beneath, no damage can be caused to the colored surface. Ordinary gloss oil can
be applied to glazed and laminating boards without any concern about the
restrictions and difficulties on pre-printing of surface papers at corrugated
lines, thereby significantly lowering the production cost of folding cartons.
Less glue consumption and high board intensity: The
tackifier for mounting can be white emulsion or starch glue, and the
consumption can be less than 20g. Even the use of low-gram papers will never
result in the omitted corrugating. Moreover, the less application of glue
brings lower water content and higher intensity and deflection of boards.
Therefore, with respect to ordinary laminating machines, this production line
can reduce a weight of 30g-50g for surface papers.
Higher equipment accuracy and lower body paper cost:
Thanks to mounting with the single corrugated board and color-printed surface
papers, the production line is free from secondary positioning. The accuracy of
side-mark mounting increases to ±0.5mm, and 2mm-5mm deckle edge can be saved
compared with single mounting. Based on a breadth of 10,000m, the utilization
of body papers can reach 4‰-10‰.
