[0052] The implementation principle of the automatic feeding device for a coating machine in this application embodiment is as follows:

[0053] When the material roller needs to be moved, the drive motor 443 drives the screw 444 to rotate. Under the limiting action of the sliding groove 4421, the slide block 445 drives the lever 446 to abut against the side of the material roller and pushes the material roller towards the material transfer ring 42. The material roller is then pushed onto the material transfer ring 42. The drive motor 61 drives the rotating column 62 to rotate. Under the connection of the drive gear 63, driven gear 65, chain 66 and transfer column 64, the material transfer ring 42 is driven to slide away from the placement table 2, and the material roller is moved to the placement table 45. The material roller slides along the material transfer plate 46 and is locked onto the fixed ring 43. The drive cylinder drives the lifting plate 53 to rise, and the lifting plate 53 drives the fixed ring 43 to rise, adjusting the position of the material roller 3 and transporting the material roller to the processing station position.
