[0021] Working principle: One end of the vehicle film 9 is fixedly wound on the unwinding shaft of the unwinding device 2, and the other end first passes through the connecting device 6 and then enters the box body 1, bypasses several rotating rollers arranged in the box body 1, and passes through the coating device 4, oven 5, detection device 7 and cutting device 8 arranged in the box body 1 in turn, and finally is wound on the winding shaft of the winding device 3.

[0022] The vehicle film 9 is pulled toward the winding device 3 for winding by the rotation of the winding shaft of the winding device 3; first, the vehicle film 9 will pass through the connecting device 6, and the cleaning structure provided in the connecting device 6 will clean the surface to be coated of the vehicle film 9; the static electricity eliminating rod 69 in the cleaning structure eliminates the static electricity on the surface of the vehicle film 9, and then the airflow generated by the blowing pipe 614 is evenly blown toward the surface to be coated of the vehicle film 9, effectively blowing away dust and impurities, ensuring the cleanliness of the surface of the vehicle film 9; the dust and impurities are sucked away and discharged through the cooperation of the cleaning hood 610 and the blower 611. The cleaned vehicle film 9 enters the coating device 4 arranged in the box body 1, and the coating device 4 coats the surface of the vehicle film 9. After the coating is completed, the vehicle film 9 enters the oven 5 for baking to solidify the coating layer; after the oven 5, the vehicle film 9 will pass through the detection device 7, and the detection device 7 detects the coating conditions of various parts of the vehicle film 9 through a number of equidistant and evenly distributed detection cameras 75 arranged thereon. When the camera collects images, it uses the background plate 76 as a reference to accurately judge the coating quality of the surface of the vehicle film 9; finally, the detected vehicle film 9 passes through the cutting device 8 and is rolled up onto the winding shaft of the winding device 3.

[0023] When the coating of the rolled film 9 placed on the unwinding device 2 is completed, another roll of film 9 needs to be replaced for coating; when the end of the front roll of film 9 passes through the connecting device 6, the sensor 67 set on the pressing structure of the connecting device 6 detects that there is no film 9 passing below, and the equipment stops working. Then, the staff puts another roll of film 9 to be coated into the unwinding device 2, and then puts the head end of the rear roll of film 9 and the end of the front roll of film 9 into the pressing structure of the connecting device 6; through the pressing structure and the hot pressing plate 66 , it can press and connect the heads and tails of two different rolls of car film 9 to ensure the continuity of the car film 9; after completing the pressing and connection, restart the equipment to coat the car film 9; when the connection between the two different rolls of car film 9 moves into the cutting device 8, start the cutting device 8, and the cutting cylinder 84 drives the cutter 85 to cut the connection between the two different rolls of car film 9; after completing the cutting, remove the coated car film 9 from the winding device 3, and wind the head end of the rear roll of car film 9 onto the winding shaft of the winding device 3 for winding.

[0024] The heads and tails of two different roll films 9 are pressed and connected by the pressing structure arranged in the connecting device 6, and the end of the front roll film 9 drives the rear roll film 9 to bypass several rotating rollers arranged in the box body 1, and passes through the coating device 4, oven 5, detection device 7 and cutting device 8 arranged in the box body 1 in sequence, thereby achieving the effect of facilitating loading, reducing the trouble of manual loading, and improving production efficiency.
