In the initial state of the first topping roller c61, the height of the first topping roller c61 is flush with the height of the material supporting arm c 4. After the first ejecting cylinder c62 drives the first ejecting roller c61 to complete the up-and-down reciprocating motion within a set time, the first ejecting cylinder c62 makes the first ejecting roller c61 keep an ejecting state, that is, the height of the first ejecting roller c61 is higher than that of the material supporting arm c4, so that the height of the plate located between the plate positioning module b and the material supporting arm c4 can be increased to the maximum extent, and the phenomenon that the plate bends downwards due to gravity in the transition process and rubs with the corner of the sliding frame c2 to affect the product quality is avoided. When the plate material constant-pressure mechanism presses the plate material, the first ejecting air cylinder c62 drives the first ejecting roller c61 to descend and reset to the initial position.
