[0002] The forming wheel of the cigarette pack transparent paper packaging machine is equipped with a heat sealing station. In the actual production process, the cigarette pack rotates in the mold box of the forming wheel, and the folded long side is protected by the arc plate and comes to the heat sealing station, where the heat sealing iron heat seals and shapes the folded long side. Due to the high operating speed of the equipment and the short heat sealing time, the cigarette pack transparent paper does not shrink sufficiently, resulting in problems such as looseness, uneven side sealing and unreliable heat sealing of the cigarette pack transparent paper packaging.
