This design makes packing machine design argument, packaging principle analysis, mechanical design and strength calculation, particle packing machine designed mainly by the supply hopper, metering feed, packaging film supply, molding, longitudinal sealing, transverse sealing , quantitative feeder, cutting, heating and other electrical ponents, its working principle is mounted on an adjustable film reel shaft axial distance, the film by the tensioning device, the guide rollers, traction roller guide into the film forming device to form a folded Ushaped configuration. Further, the longitudinal sealing rollers transverse sealing the film into a tubular shape, transverse sealing the tubular film roll at the bottom of the seal, made of open pocket, to open the bag feeding mechanism for filling material, and horizontal sealing rollers seal the mouth of the pocket open , cutter cutting device into a continuous bag single bag, plete packaging process. The machine has good integrity, high precision, high efficiency, safety and reliability, easy operation, and low manufacturing costs.
