[0002] A printing press is a machine that prints text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. They play an important role in the dissemination of human civilization and culture, and the paper collection mechanism of the printing press is also an important component of the printing press.

[0003] The prior art discloses a paper receiving device for a printing press with the publication number CN220078088U, which includes a support base, and an air-drying storage mechanism for preventing paper jams, including slides provided on both sides of the inner wall of the support base, a limit plate is provided between the inner walls of the two slides for sliding movement, an electric telescopic rod is provided on one side of the inner wall of the two slides for locking, a storage box is fixedly provided on one side of the outer wall of the support base, mounting grooves are provided on both sides of the inner wall of the storage box, and fans are provided on the inner walls of the two mounting grooves. In the utility model, when the upper printing press unloads paper, it directly slides onto the slope of the support base through the inclined plate, and normal paper will slide into the storage box along the slope. When a paper jam occurs, the electric telescopic rod is started to make the limit plate slide in the slide and push the paper to move so that it falls smoothly into the storage box, and then the fans in the mounting grooves at both ends are started to make the air in the storage box flow quickly, accelerating the drying of the ink marks on the upper end of the paper, thereby improving the practicality of the device.
