(1) Opening device: starting a first unreeling device, a second unreeling device, an adhesive guide roller, a first traction roller, a second traction roller, a constant-temperature water circulation system, a heating device and a reeling device; the first unreeling device is positioned at the upstream of the bonding guide roller; the second unreeling device is positioned at the upstream of the first traction roller; an upstream gap between the bonding guide roller and the first traction roller forms a bonding port of the first planar film and the double-layer single-sided bubble film; the second traction roller is positioned at the downstream included angle of the bonding guide roller and the first traction roller, and a gap between the second traction roller and the first traction roller forms a traction opening of the double-sided non-medium printing bubble film; the constant-temperature water circulation system is used for controlling the temperature of the circulating cooling medium in the bonding guide roller; the heating device provides heat for softening the first planar film and the double-layer single-sided bubble film;
(2) Conveying raw materials: the first unreeling device is used for conveying a first plane film with a printing layer on the surface, and the first plane film is guided into a gap between the bonding guide roller and the first traction roller through the bonding guide roller; the second unreeling device is used for conveying double-layer single-sided bubble films, and the double-layer single-sided bubble films enter a gap between the bonding guide roller and the first traction roller along with the rotation of the first traction roller; the rotation and running speeds of the first traction roller and the bonding guide roller are the same and are 0-30 m/min; the rotation directions of the first traction roller and the bonding guide roller are opposite;
(3) Softening by heating: the heating device comprises an air duct, a fan, a heating box, a temperature sensor I and a temperature control device; an air outlet of the air duct is aligned with an upstream gap between the bonding guide roller and the first traction roller, the fan continuously conveys air to the heating box, the heating box heats the air by heat emitted by internal electric stove wires, the heated air is subjected to temperature detection by a temperature sensor I at the position of the air inlet of the air duct, the temperature sensor I transmits a temperature signal to a temperature control device, the temperature control device controls the opening and closing of the electric stove wires in the heating box according to the set temperature and the current detected temperature, finally, the temperature of the air entering the air duct is controlled, and the temperature of the air entering the air duct is controlled to be 120-200 ℃; in the process that the plane film with the printing layer is guided to a gap between the bonding guide roller and the first traction roller through the bonding guide roller, the first plane film is closer to an air outlet of the air duct, the first plane film absorbs heat of air blown by the air duct, when the heat absorbed by the first plane film reaches a certain degree, the first plane film begins to soften, in the process that the first plane film absorbs heat and softens, part of heat of the first plane film is taken away by a circulating cooling medium in the bonding guide roller, the first plane film is prevented from being overheated, and the temperature of the cooling medium is controlled between 50 ℃ and 80 ℃ through a constant-temperature water circulation system; in the process that the double-layer single-sided bubble film advances to an upstream gap between the bonding guide roller and the first traction roller, the top of the bulge of the double-layer single-sided bubble film is slowly close to an air outlet of the air duct, the double-layer single-sided bubble film absorbs heat of air blown out by the air duct, and when the heat absorbed by the double-layer single-sided bubble film reaches a certain degree, the top of the bulge of the double-layer single-sided bubble film begins to soften; in the process of heat absorption and softening of the double-layer single-sided bubble film, part of heat of the double-layer single-sided bubble film is taken away by circulating cooling water in the first traction roller; the direction of the air outlet of the air duct can be adjusted in angle according to production requirements; the bonding guide roller can be adjusted up and down and left and right according to production requirements;
(4) And (3) bonding and cooling: when the softened first planar film with the printing layer and the double-layer single-sided bubble film simultaneously pass through a gap between the bonding guide roller and the first traction roller, the first planar film is contacted with the convex top of the double-layer single-sided bubble film and bonded together to form a double-sided medium-free printing bubble film, the double-sided medium-free printing bubble film enters the gap between the first traction roller and the second traction roller through the guide of the first traction roller, and the temperature of circulating cooling water inside the second traction roller and the first traction roller is controlled to be lower than 60 ℃ for cooling the double-sided medium-free printing bubble film; the size of a gap between the bonding guide roller and the first traction roller is matched with the integral thickness formed by effective bonding of the first planar film and the double-layer single-sided bubble film, and the size of the gap between the bonding guide roller and the first traction roller can be adjusted according to production requirements;
(5) And (3) rolling: and along with the rotation of the second traction roller and the first traction roller, the double-sided medium-free printing bubble film with the printing layer leaves the second traction roller and the first traction roller and is rolled into a bubble film roll by the rolling device, so that the preparation of the double-sided medium-free printing bubble film is completed.
