Description

Technical Field

[0001] The utility model relates to the technical field of sealing and shaping of transparent paper for cigarette packages, in particular to an ironing mechanism of a low-temperature ironing device. Background Art

[0002] With the development of the tobacco packaging industry, many brands pay special attention to the beauty of small-pack transparent paper in order to pursue more exquisite packaging effects. In order to better meet market needs, continuously improving product quality has become a very important task at present. Continuously improving the exquisiteness of product surface appearance, continuously meeting consumers' higher demands and improving product grades have also become the main driving force for the development of the industry. Upgrading the existing six-station forming wheel and negative pressure six-station forming wheel product equipment and rapidly improving the performance of existing product equipment is an effective means to promote the development of this industry.

[0003] The basic working principle of the existing forming wheel is as follows: after the cigarette pack is intermittently stepped from the left side of the main machine into the first station where the left side of the six-part forming wheel stops horizontally, the forming wheel intermittently rotates clockwise and then rotates the cigarette pack from the first station to the second station. During the interval when the cigarette pack stops rotating, the cigarette pack enters the first station again, and the second station is pressed by the reciprocating soldering iron above, which is ironed once and then lifted. According to the same steps, the forming wheel continues to rotate intermittently to rotate the cigarette pack from the second station to the third station. During the interval when the cigarette pack stops rotating, the cigarette pack is pressed by the reciprocating soldering iron above, which is ironed twice and then lifted. The cigarette pack is rotated to the fourth station again and then pushed out of the cabin to leave the forming wheel, completing the entire process of ironing the side of the cigarette pack. During this process, there are always cigarette packs in the first, second, third, and fourth stations, and the fifth and sixth stations are vacant.

[0004] To sum up, two groups of the six-station forming wheel are responsible for loading and unloading cigarette packs, two groups are responsible for idling, and only two groups are responsible for sealing and shaping the cigarette packs. Therefore, it is necessary to increase the temperature of the two groups of soldering irons. Excessive temperature will not only cause the aging speed of various parts in the equipment, but also have higher requirements on the material of the transparent paper, making it more difficult to shape the transparent paper packaged on the cigarette packs.
