Description

Technical Field

[0001] The utility model relates to a paper feeding device of a printing press, in particular to a pre-paper feeding anti-scratch feeder head device. Background Art

[0002] The continuous paper feeder in a printing press is also known as a paper feeder. Its function is to periodically separate sheets from the paper pile and deliver them to the feed rollers. The feeder head operates at very high speeds, and to keep pace with this speed, a paper stack conveyor is required. Existing paper stack conveyor mechanisms typically only utilize a single cardboard alternating lift mechanism and lack pre-loading capabilities. This results in a long wait for the alternate lift mechanism to deliver paper after the feeder head has finished delivering a stack of cards, impacting paper delivery efficiency.
