s1: firstly, a heat shrinkable film passes through a feeding channel (8), then the heat shrinkable film is connected with one of two winding rollers (5), a switch of a driving motor (3) is turned on, an output shaft of the driving motor (3) drives one group of transmission gears (41) and a rotating shaft (4) to rotate, the other group of transmission gears (41) and the rotating shaft (4) rotate in opposite directions under the action of two meshed transmission gears (41), the winding rollers (5) can wind the heat shrinkable film, the heat shrinkable film can play a role in pushing a contact driving block (63) along with the increasing thickness of the heat shrinkable film wound on the winding rollers (5), so that a bending rotating plate (61) rotates, a cutting blade (62) can cut the heat shrinkable film, the winding rollers (5) containing the heat shrinkable film can be manually taken down, and meanwhile, the contact driving block (63) can push a rotating control plate (71) to rotate through a connecting plate (631), the rotary control plate (71) can drive the push plate (72) to push the rotary guide plate (73), so that the rotary guide plate (73) can move the heat shrinkable film to a position close to a winding roller (5) which is not wound with the heat shrinkable film and wind the heat shrinkable film on the surface of the winding roller (5);

s2: the method comprises the following steps that a friction plate (632) is fixedly installed on a contact driving block (63), when a thermal shrinkage film on a winding roller (5) containing the thermal shrinkage film pushes the contact driving block (63) and a bending rotating plate (61) to rotate, the other contact driving block (63) is close to the winding roller (5) not containing the thermal shrinkage film until the friction plate (632) is in contact with the winding roller (5), in the rotating process of the winding roller (5), a friction layer of the friction plate (632) can rub against the winding roller (5) to enable the winding roller (5) to carry static electricity, and when a subsequent guide mechanism (7) guides the thermal shrinkage film, the static electricity on the winding roller (5) can have an adsorption effect on the thermal shrinkage film to improve the effect that the thermal shrinkage film is close to the winding roller (5);

s3: glue is injected into the glue storage elastic bag (633), in the rotating process of the contact driving block (63), the glue is extruded between the glue storage elastic bag (636) and the winding roller (5), the winding roller (5) drives the driving plate (635) to move when deformed, the push block (6351) on the driving plate (635) can push the extrusion rod (634) to move and extrude the glue storage elastic bag (633), the glue in the glue storage elastic bag (633) is extruded out through the extrusion type elastic switch (6331) and coated on the surface of the center of the winding roller (5), when the heat shrinkable film is adsorbed on the winding roller (5), the adhesion between the heat shrinkable film and the winding roller (5) is realized, so that the stability of the heat shrinkable film on the winding roller (5) is improved, and when the distance between the contact driving block (63) and the winding roller (5) moves to the minimum, the extrusion rod (634) is positioned at the joint of the arc-shaped part and the straight-shaped part of the push block (6351), when the heat shrinkable film is wound on the winding roller (5), the thickness of the winding roller (5) is increased, the winding roller (5) can further extrude the elastic protruding sheet (636), at the moment, the push block (6351) continues to move, so that the extrusion rod (634) is clamped at the straight part of the push block (6351), and at the moment, the position of the transmission plate (635) is manually reset;

s4: in the rotating process of the winding roller (5), the vibration groove (51) can collide with the vibration strip (6312), so that the winding roller (5) can vibrate integrally, so that the adsorbed dust on the winding roller (5) falls off, the dust in the air caused by the static on the winding roller (5) is attached to the winding roller (5), in the vibration process of the winding roller (5), the inner wall of the reinforcing cavity (52) vibrates along with the winding roller (5) and plays a certain driving force for the vibration reinforcing balls (53), so that the vibration reinforcing balls (53) move inside the reinforcing cavity (52), the hemispherical protrusions inside the reinforcing cavity (52) enable the vibration reinforcing balls (53) to move irregularly inside the reinforcing cavity (52), and the impact of the vibration reinforcing balls (53) on the hemispherical protrusions inside the reinforcing cavity (52) can improve the vibration effect of the winding roller (5).
