The present invention relates to a corrugated packing carton making molding processing machine and molding processing technology, comprising a fixed base, a transmission device, a transmission belt, a mounting frame and a mounting plate, the upper end of the fixed base is provided with a transmission device, and the upper end of the transmission device passes through A transmission belt is connected in a sliding fit mode, a mounting frame is installed in the middle of the upper end of the fixed base, and a mounting plate is fixed in the upper end of the mounting frame. The invention can solve the problem that in the traditional round corrugated box forming automatic processing process, glue is often used at the joint between the cylinder and the bottom support. For heavy items, the load-bearing capacity of the glued round corrugated box is relatively low. Poor, it will cause the butt joint of the cylinder and the bottom bracket to fall off, and in the process of processing, it is necessary to manually fix the position of the cylinder and the bottom bracket of the corrugated box, and then deal with the joint, usually lack of joints Pressure-holding treatment, and the manual fixing effect is poor, which is not convenient for automatic production and other problems.
