Through the film material supply mechanism, only the feeder 41 needs to move relative to the material supply seat 31 in the whole material supply process, the material supply mechanism is simple, the material supply step is simple and convenient, and the film material supply and whole film coating process efficiency is improved.

In one embodiment of the present invention, the feeder 41 is linearly movable relative to the feeder 31, so as to achieve two states, i.e., the discharge hole 44 is exposed from the feeding seat 31 or blocked by the feeding seat 31. In another embodiment, the feeder 41 can also rotate relative to the feeder 31, and the feeder 31 can have an opening, when the feeder 41 rotates a certain angle, the supply outlet 44 can expose the supply seat 31 through the opening, and when the feeder 41 rotates another angle, the supply outlet 44 is blocked by the supply seat 31 again.

As shown in fig. 1 and 2, in one embodiment, the material supply base 31 is in a sleeve shape and is inserted into an opening of a wall of the vacuum coating chamber 1, a main portion of the sleeve extends into the vacuum coating chamber 1 through the opening of the wall, a flange 33 is provided at a rear portion of the material supply base 31, the flange 33 abuts against an outer side of the wall of the vacuum coating chamber 1, and the flange 33 is fixed to the wall of the vacuum coating chamber 1 by bolts or welding, so that the material supply base 31 is fixed to the wall of the vacuum coating chamber 1.
