[0027] It should be noted that: The raw materials on the polyolefin film raw material roller 4 and the adhesive film raw material roller 5 respectively pass through the corresponding dust adhering rollers 204. The four tension springs 203 pull the corresponding slide bars 202, so that the two dust adhering rollers 204 slide directionally along the four sleeves 201, and then closely adhere to the polyolefin film raw material roller 4 and the adhesive film raw material roller 5, and adhere and adsorb the impurities and dust attached to their surfaces. Adhesive glue is coated on the outside of the two dust adhering rollers 204.

[0028] In the specific implementation process, refer to Figure 1 and Figure 3 As shown, the composite structure 6 includes a support frame 601.

The four tension springs 203 pull the corresponding sliding rods 202 to realize the directional sliding of the two dust-removing rollers 204 along the four sleeves 201, and then closely adhere to the polyolefin film raw material roller 4 and the adhesive film raw material roller 5, adhering and adsorbing the impurities and dust on their surfaces. Then, the liquid pump 302 generates suction to adsorb the glue liquid in the glue box 301 to the two equalizing pipes 303. The two equalizing pipes 303 evenly distribute the glue liquid to a number of nozzles 304 for spraying, so as to realize uniform coating on the surfaces of the polyolefin film raw material and the adhesive film raw material. Then, the electric telescopic rod 604 performs telescopic actions to control the displacement of the movable pressing roller 605 towards the fixed pressing roller 603, and the motor 606 controls the rotation of the fixed pressing roller 603 to achieve squeezing and compacting the polyolefin film raw material and the adhesive film raw material. The fixed pressing roller 603 transmits the rotational power to the driving pulley 701. The driving pulley 701 uses the transmission belt to control the synchronous rotation of the driven pulley 702, and then controls the rotation of the winding roller 703 to wind and press the completed composite film.
