Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging, in particular to a uniformly heated cigarette box mold body. Background Art

[0002] Cigarette packaging is usually made of thin plastic. The plastic packaging needs to be ironed to ensure the fit. However, it should be noted that the temperature should not be too high during ironing to prevent the plastic from melting or deforming. At the same time, the cigarette box should not stay in the same position for too long during ironing, otherwise it will easily cause thermal damage to the cigarette box. Finally, after ironing, make sure that the plastic packaging is completely cooled before moving or handling it to avoid damaging the plastic. Therefore, the temperature control during ironing is the most important.

[0003] In order to solve the above technical problems, Chinese patent CN113290943A discloses a degradable plastic ziplock bag plastic seal strip pasting device and pasting process, including a bottom fixed plate, a folding roller drive motor, a roller drive motor and a cutting drive motor, the bottom fixed plate is fixedly provided with a pasting operation table, and the pasting operation table is provided with a plastic seal strip feeder, a hot pressing paster and a cutter from left to right. The above patent uses the power transmission mechanism and the gear box to make the moving distance of the movable discharge table together with the three-phase laminator exactly the same as the moving distance of the fixed plate, thereby ensuring the uniformity of the heating distance, so that the production of plastic ziplock bags does not need to use larger plastic films, saving raw material costs. However, the above patent cannot further iron the film that has been coated on the cigarette box, and the temperature of the ironing heating cannot be effectively controlled.

[0004] Therefore, it is necessary for those skilled in the art to provide a uniformly heated cigarette box mold body, further iron the film already wrapped on the cigarette box, ensure the fit of the film, and improve product quality. Utility Model Content
