Research and Application of Motor-Driven Gear-Rack Pre-compression Packaging Machine Set

The tobacco sheet pre-compression and packaging machine is primarily used for the pre-compression and packaging process in the reconstituted tobacco production line. It compresses the loose reconstituted tobacco sheets (after being weighed) that have been sliced by a shredding machine and boxed into a tobacco sheet pile of a specific size and specification, meeting the packaging and transportation requirements of subsequent processes. Currently, pre-compression and packaging machines in the reconstituted tobacco industry utilize hydraulic systems for packaging due to their unique characteristics and installation positions (with piston rods and pressing heads located within the packaging material box). The transmission medium primarily relies on hydraulic oil. During the process of the piston rod descending to compress the package, the piston rod emerges from the main cylinder, bringing out a certain amount of oil film, which poses a risk of contamination in the tobacco leaves. Starting from the source of risk control, namely the hydraulic oil, this paper conducts research and design on the power source of pre-compression and packaging. The power system is converted from hydraulic drive to electric motor drive, transforming the hydraulic pre-compression and packaging machine into an electric motor-driven rack and pinion pre-compression and packaging machine. This change eliminates the risk of oil contamination from the source and simultaneously achieves effective energy savings and reduces spare part and maintenance costs.
