The utility model discloses a whole stack paper box backing paper pre-wrapping mechanism which comprises a
machine frame, a paper placing platform, a first adsorption mechanism, two edge folding clamping plates and two first lifting mechanisms, the
machine frame is provided with a paper supply
station, the paper placing platform is provided with a paper placing
station, and the two edge folding clamping plates are arranged on the paper placing
station. The rack is provided with a position switching mechanism capable of driving the first adsorption mechanism to switch the position between the paper supply station and the paper placing station, the first adsorption mechanism is installed at the
power output end of the position switching mechanism, and the adsorption direction of the first adsorption mechanism is arranged downwards; two vertically-through inserting holes are formed in the paper placing platform, the two inserting holes are located in the same straight line and form the paper placing station, the two first lifting mechanisms are both installed at the bottom of the paper placing platform, the
power output ends of the first lifting mechanisms are arranged upwards, and the two edge folding clamping plates are installed at the
power output ends of the corresponding first lifting mechanisms respectively. The two edge folding mechanisms are located below the two inserting holes and can move up and down in the corresponding inserting holes.
