Abstract: For preventing emulsion adhesive from developing a solid layer on its surface, an emulsion adhesive stirring and water compensating device was designed and applied to a CT cartoner. Driven by an independent motor, the device stirred the adhesive continuously when the machine was stopped temporarily. The automatic water compensating to adhesive was controlled by a PLC control system. The results of application showed that the solid surface layer was effectively reduced, thereby adhesive waste dropped from 4.22 to 1.08 kg/machine per week. Moreover, the consistence of emulsion adhesive were guaranteed, and maintenance work was decreased.
