Paper card opening mechanism and paper card feeding device

Abstract

The invention relates to a paper card opening mechanism and a paper card feeding device. The paper card opening mechanism comprises a mounting frame, a plurality of swing arms, a first power mechanism and a transmission assembly. The multiple swing arms are sequentially arranged at intervals and rotationally arranged on the mounting frame, and each swing arm comprises two grabbing arms which are oppositely arranged at intervals. The two grabbing arms are arranged on the two opposite sides of the paper card respectively and can fix or loosen the paper card. All the swing arms are connected with the transmission assembly, the first power mechanism is used for driving the transmission assembly to act, and the transmission assembly can drive all the swing arms to rotate. In the using process, the two grabbing arms of each swing arm are arranged on the two opposite sides of a paper card correspondingly and fix the paper card. However, the first power mechanism drives the transmission assembly to act, the transmission assembly drives all the swing arms to rotate, and therefore the paper cards in the folded state can be rotationally opened. And after the paper card is opened, the paper card is conveyed to a target position. Therefore, the paper card can be automatically opened, the working efficiency is high, and the labor cost is low.
