Description

Technical Field

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

[0002] When printing paper, a paper pick-up device is required to pick up the paper. The printing paper pick-up device is a device that grabs a whole stack of unprinted paper one by one and places it on the printing press.

It has the advantages of being able to drop the attached paper below in the process of grabbing the paper and being easy to use.

[0004] The existing technology still has shortcomings:

[0005] In the above-mentioned prior art, the paper is gripped by a suction cup, and the excess paper under the suction cup is dropped by rotating.

As a result, it is difficult to ensure that the paper to be gripped is in a straightened state during the next grip, which affects the gripping of the paper. Therefore, a printing paper picking device is proposed. Utility Model Content
