[0018] The utility model has the following beneficial effects:

[0019] 1. Compared with the prior art, the automatic coating device for epoxy coated paper, through the paper inlet, the second motor, the first shaft, the first roller, the first gear, the second gear, the second shaft, the second roller, the paper outlet, the third roller, the nozzle, the second pulley, the belt, the first pulley, the third gear, the fourth gear, the fourth roller, the second groove, the first motor, the screw rod, the baffle, the upper left roller, the lower left roller, the lower right roller and the upper right roller, when the epoxy coated paper enters from the paper inlet, the second motor works to drive the first shaft to rotate, and then drives the first roller and the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the second shaft to rotate, and the second shaft drives The second roller is driven to rotate. At this time, the paper can pass between the first roller and the second roller, and the paper is driven to move toward the paper outlet. Before reaching the third roller, the nozzle sprays the upper surface of the paper. When the paper moves to the third roller, the rotation of the first gear drives the second pulley to rotate, which in turn drives the belt transmission, which in turn drives the first pulley to rotate, which in turn drives the third gear to rotate, which in turn drives the third roller to rotate. The rotation of the third gear also drives the fourth gear to rotate, which in turn drives the fourth roller to rotate. Since the second groove is filled with paint, the third roller will be coated with paint on the surface of the third roller when it rotates. When the paper passes through the third roller and the fourth roller, When the paper passes between the first and second rollers, the fourth roller can apply paint to the lower surface of the paper. At the same time, the distance between the third roller and the fourth roller is small, and the excess paint on the paper will be intercepted, so that the paint on the paper is evenly coated, and finally the paper is discharged from the paper outlet. When papers of different sizes need to be coated, the first motor is driven to drive the screw to rotate, and then drive the adjacent baffles to move to a position away from the center of the device, and then drive the upper left roller and the lower left roller to move to the left, and the upper right roller and the lower right roller to move to the right, so that the length of the first roller and the second roller becomes longer, and the distance between the baffles becomes longer, so that the size of the paper that can be accommodated becomes larger, and papers of different diameters can be accommodated. The paper passes between the baffles, The baffle plays a limiting role. Compared with the existing automatic coating device, which can usually only coat epoxy coated paper of a single size, when facing epoxy coated papers of multiple sizes, it may be necessary to add some components to the equipment to coat epoxy coated papers of different sizes, which is more troublesome and also increases the coating cost of epoxy coated paper. When in use, the automatic coating device can change the length of the first roller and the second roller according to the different sizes of paper, and then change the spacing between the baffles, so that the size of the paper that can run between the baffles can be changed, and epoxy coated papers of different sizes can be coated, reducing the coating cost of epoxy coated paper.

[0020] 2. Compared with the prior art, this automatic coating device for epoxy coated paper uses a nozzle, a third roller, a fourth roller and a second groove. When the upper surface of the epoxy coated paper is sprayed by the nozzle, the paper moves between the third roller and the fourth roller to squeeze and intercept the excess coating on the epoxy coated paper, and finally falls into the second groove, so that the coating is uniform and the excess coating is not wasted, which saves more costs.
