Beneficial effect: The utility model adopts a pressure plate and a vacuum pump. The spring pushes the pressure plate to apply pressure to prevent the green printed product from warping and being unable to pass through the baffle, and to prevent the material from getting stuck. The feeding belt rotates, and the friction force drives the green printed product at the bottom to move through the bottom surface of the baffle. During the feeding process, the vacuum pump is started to extract the air in the exhaust pipe, the suction pipe and the suction port. The top surface of the suction port slides against the inner surface of the feeding belt, and the air is connected to the through-hole surface to cause negative pressure, which sucks the bottom surface of the green printed product at the bottom, improves adhesion, and cooperates with the friction between the feeding belt and the green printed product at the bottom, reducing the slippage between the green printed product and the feeding belt, and further improving the stability of feeding.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned solution has the following problems: when in use, it is not convenient to clean the surface of the printed product; during the transfer and transportation of the printed product to the quality inspection machine, dust and impurities in the environment are easy to adhere to the surface of the printed product, and the dust can easily cause inaccurate inspection during inspection, thereby reducing the inspection effect and efficiency of the printed product.

The height of the baffle 19 is less than the thickness of the printed product;

[0027] A lifting mechanism is provided on the top of the base 1 and on one side of the feeding mechanism, and a fixed plate 3 is connected to the output end of the lifting mechanism.
