Automatic folding calibration device for compression bag production

The utility model relates to the technical field of compressed bag production, in particular to an automatic folding and calibrating device for compressed bag production, which comprises a workbench, a hydraulic cylinder is mounted on the lower surface of the workbench, and the output end of the hydraulic cylinder is movably connected with a folding plate through a transmission part. According to the automatic folding calibration device for compressed bag production, firstly, a compressed bag needing to be machined is placed on the upper surface of the folding plate, the size of the folding plate is matched with the specified production standard size of the compressed bag, then the motor is started, the motor drives the lead screw to rotate, the lead screw drives the guide rod to move along the guide rod in the rotating process, and the compressed bag is folded and calibrated along with movement of the guide rod. The first connecting rod on the outer wall of the guide rod begins to deviate, the first connecti
