Automatic paper collecting device for stacking of stacking machine

The invention discloses an automatic paper collecting device for stacking of a stacking machine. The automatic paper collecting device comprises a paper collecting transmission mechanism, a supportingmechanism and a paper collecting mechanism. The paper collecting transmission mechanism is installed at the upper portion of the supporting mechanism. Linear sliding rails are arranged on the inner sides of the left part and the right part of the supporting mechanism correspondingly. Linear sliding blocks are arranged on the linear sliding rails. The paper collecting mechanism comprises a paper collecting rod cross beam at the upper portion and multiple paper collecting rods fixed below the paper collecting rod cross beam. The two ends of the paper collecting rod cross beam are fixedly connected with the linear sliding blocks through connecting blocks, and chain connecting plates are further fixed to the two ends of the paper collecting rod cross beam. The paper collecting transmission mechanism is connected with
