Conveyor system is designed according to packaging line equipment composition and plant building layout to achieve smooth bottle/pack flow and line efficiency. Meanwhile, good looking of the workshop as a whole shall also be considered. Main characteristics: partial application of non-pressure control ensures line efficiency on one hand while reduces bottle collision on the other hand; modular design allows product diversity/simplicity/ interchangeability and easy installation/maintenance; centralized lubrication advantages time saving and labor saving.
