Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette films, and in particular relates to a hot film auxiliary sealing device. Background Art

[0002] Cigarette film is a thin film material used to package tobacco products. It is usually made of a special material with certain air permeability and moisture resistance, and is designed to maintain the freshness and quality of cigarettes. Cigarette film is generally covered on the outer layer of cigarette packaging paper, and has certain flexibility and wear resistance to ensure the integrity of the packaging and protect cigarettes from damage. Cigarette film can also effectively protect tobacco products from moisture, contamination and damage, and can also improve the appearance and quality of the product. When packaging tobacco products with cigarette film, it is necessary to combine the cigarette film with the surface of the tobacco product by heating to ensure the firmness and sealing of the packaging. A hot film machine and a hot shovel are required to heat the cigarette film. The heating temperature and time need to be determined according to the characteristics of the cigarette film material and the requirements of the tobacco product. In short, by hot filming, a firm connection can be formed between the cigarette film and the tobacco product to prevent the tobacco product from being damaged or contaminated during transportation and storage. At the same time, hot film can also improve the sealing of the packaging, extend the shelf life of tobacco products, and maintain the freshness and taste of the product.

[0003] Currently, when using a hot spatula to heat the film, there is electrostatic adsorption between the hot spatula and the cigarette film, which causes the cigarette film to be adsorbed on the surface of the hot spatula, affecting the film sealing and making the film sealing irregular.

By setting the first hot surface to an isosceles trapezoidal plate structure, the film is gradually sealed from the middle of the long side to both sides, which is conducive to ensuring the flatness of the sealing. By setting the distance between the limit block and the front end of the positioning block to 2 cm, the coverage area of ​​the positioning block on the surface of the cigarette film is reduced while fixing the cigarette film, and the sealing is not affected. By setting the positive electrode needle and the negative electrode needle, positrons and negative electrons can be released to neutralize the positrons and negative electrons on the surface of the cigarette film, thereby avoiding the existence of static electricity on the surface of the cigarette film so that the cigarette film is adsorbed on the surface of the hot film auxiliary sealing device, affecting the sealing. By setting the discharge point to be a five-pointed star, the contact area can be increased, the efficiency and stability of electrostatic discharge can be improved, so that the discharge point forms more contact points with the surface of the cigarette film, thereby discharging static electricity more evenly and reducing local overheating or damage caused by single-point discharge. The invention can solve the problem that when using a hot spatula to hot the film, there is electrostatic adsorption between the hot spatula and the cigarette film, which causes the cigarette film to be adsorbed on the surface of the hot spatula, affects the film sealing and makes the film sealing irregular.
