In actual production process, according to the different materials of packaging bag film, a certain clamping time is needed. In order to make the sealing of packaging bag tight and beautiful, it is necessary to increase the sealing pressure and prolong the clamping time. When the liquid product film itself has a certain thickness or special material, in order to ensure sufficient sealing conditions, the production speed of multi-column packaging machine column will be greatly reduced. At the same time, the transverse sealing sealing lifting drive of multi-column packaging machine used in the market is mostly servo motor driven lifting screw, which drives screw nut to drag the whole transverse sealing mechanism to move up and down.
