Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding devices, in particular to a non-stop paper feeding device. Background Art

[0002] At present, the paper feeding device of printing presses is usually realized by feeder, which is a component that separates individual sheets of paper from the paper pile and outputs them accurately. In order to increase the paper feeding speed of the printing press, the feeder is usually kept working without stopping. During this period, the paper pile under the feeder needs to be continuously increased to keep a sufficient amount of paper.

[0003] The existing paper loading device of the printing press mainly consists of two transmission mechanisms that control the two support frames up and down respectively. The paper pile being output by the feeder is the old paper pile, and the paper pile that needs to be filled is the new paper pile. The insertion roller and the paper pile plate are replaced manually to achieve the continuous overlap of the new paper pile and the old paper pile, and finally achieve the paper pile to maintain a suitable height so that the feeder can work without stopping.

[0004] The patent with publication number CN 114506700 B discloses a non-stop paper feeding device, including a chassis and a feeder, the chassis is provided with a paper inlet and a paper outlet, and also includes a paper pile frame, a first insertion roller frame, a second insertion roller frame, a first insertion roller, a second insertion roller and a driving mechanism, the paper pile frame is slidably connected to the chassis, the paper pile frame is located at the paper inlet position, the paper pile frame can slide along the paper inlet direction, the first insertion roller frame is fixedly connected to the inner wall of the chassis, the second insertion roller frame is slidably connected to the chassis, the first insertion roller is slidably connected to the first insertion roller frame, the second insertion roller is slidably connected to the second insertion roller frame, the driving mechanism is installed on the chassis, and the driving mechanism drives the second insertion roller frame Moving in the vertical direction, the first and second roller frames, the first and second rollers allow the new paper pile and the old paper pile to overlap without stopping the feeder, which can reduce the manual operation steps and the labor intensity of the workers.
