Description

Technical Field

[0001] The utility model relates to the technical field of toilet paper production equipment, in particular to a flattening device for facial tissue production. Background Art

[0002] In the traditional facial tissue production process, the roll of paper must pass through several rollers to flatten it before being rewound. When the paper roll is subjected to mechanical forces during this rolling process, friction and compression generate heat within the paper. This heat accumulates within the paper, causing localized temperature increases and, in turn, thermal expansion.

[0003] After rewinding into a roll, the cooling rates of the inner and outer layers differ significantly. This discrepancy can easily cause the roll to curl during subsequent storage and use, severely impacting the consumer experience. Furthermore, this difference in cooling rates between the inner and outer layers can lead to inconsistent fiber shrinkage in different parts of the roll. Uneven fiber shrinkage not only reduces the overall strength of the roll but can also affect its toughness.

[0004] Therefore, it is necessary to propose a flattening device to solve the problem of heat accumulation during the flattening process of paper. Utility Model Content
