Description

Technical Field

[0001] The utility model relates to the technical field of printing press feeding, in particular to a printing press feeding device. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating a printed product identical to the printing plate.

[0003] At present, when a printing machine is loading materials, a suction clamping structure that can be displaced and raised is configured at the chassis of the printing machine. After the suction clamping structure sucks up the sheet at the material seat with a suction cup, the sheet is sucked up and moved to the conveyor belt of the printing machine for transportation and printing. However, when this feeding device is performing suction clamping and sheet feeding, the sheets are easily adhered to each other due to stacking, which causes the sheets to be sucked away and enter the bottom of the printing machine, thereby resulting in the production of defective printing products. For this reason, we propose a feeding device for a printing machine. Utility Model Content
