[0022] When working, the film material enters the utility model through feeding, and then is guided to move by guide roller 2 as one of the guiding devices. When the film material enters the gap 4, the position of the film material in the gap 4 is in the state of "about to contact with the guide roller 2 but not yet", and the film material in this state has contacted with the coating head 31 at this time, and is coated by the coating head 31; the film material after coating will leave the gap 4, and the end not coated will contact with the guide roller 2, so as to move through the guide roller 2 and enter the next station.

[0023] The utility model changes the relative position between the guide roller 2 and the coating head 31, so that the coating head 31 coats the film material in the gap 4 which does not contact with the guide roller 2, at this time, the film material is necessarily straightened due to tension, so that the film material can also be in contact with the coating head 31 when the thickness of the film material is small; when the thickness of the film material is large, the film material still has a buffer space in the gap 4 because it is not limited by the guide roller 2, so as to avoid being scratched by the coating head 31, and the effect of improving the coating quality is achieved.

[0024] In the embodiment, the angle between the output end of the coating head 31 and the horizontal plane is 40-50°, preferably 45°. Under this angle, the coating head 31 can reliably coat the coating material to the film material, and the coated film material can quickly switch the posture after leaving the gap 4, so as to avoid the coating material from separating from the film material under the action of gravity, and the coating effect is ensured.
