The lead screw 16 is in threaded cooperation with the moving plate 12, and the guide rod 11 restricts the moving track of the moving plate 12 to drive the moving plate 12 to move up and down reciprocally. The material supporting frame 13 is connected to the moving plate 12 as a whole to drive the material supporting frame 13 to move up and down reciprocally. The pulleys 14 are installed on the material supporting frame 13. The material supporting frame 13 drives the pulleys 14 to fit with the material outside the feeding roller 2 to support the material on the feeding roller 2, making the process of the feeding roller 2 driving the material to rotate more stable. And during the discharging process, as the material gradually decreases, the material supporting frame 13 drives the pulleys 14 to gradually rise to drive the pulleys 14 to always fit with the material.

The first cylinder 9 can drive the sliding frame 6 to slide on the slide rail 5. One side of the sliding frame 6 is provided with a plug 8, so as to drive the plug 8 to move towards the loading roller 2, and then insert the plug 8 into the slot 10 inside the loading roller 2 to fix the loading roller 2 and the plug 8 as a whole, and install the loading roller 2 on the top of the left side of the main frame body 1. At this time, the self-locking motor 7 can drive the loading roller 2 to rotate through the plug 8 to automatically feed the material on the outer side of the loading roller 2. When the material on the loading roller 2 is used up, the output end of the first cylinder 9 can drive the plug 8 to withdraw from the inside of the slot 10 to remove the loading roller 2 from the main frame body 1, so as to solve the problem that it takes too much time to disassemble and install the loading roller by a manual cylindrical fixture in the prior art, which affects the working efficiency of the coater.
