Filling and sealing machine adopts closed and semi-closed filling paste, liquid, sealing no leakage, filling weight, capacity consistency, filling, sealing, printing once completed, suitable for pharmaceutical, daily chemical, food, chemical and other fields of product packaging. Such as: dermatitis, ointment, hair dye, toothpaste, shoe polish, adhesive, AB glue, epoxy glue, neoprene glue and other materials filling and sealing door. It is an ideal, practical and economical filling equipment for pharmaceutical, daily chemical and fine chemical industries. The experimental results show that the maximum shear rate and the average shear rate increase with the increase of rotational speed when the blade diameter is fixed for any slurry type. But when the rotational speed is constant, the relationship between maximum shear rate and average shear rate and blade diameter is related to slurry type. When the rotational speed is constant, the maximum shear rate of radial blade increases with the increase of blade diameter, but the average shear rate is independent of the blade diameter. These concepts of blade shear rate require special care in the design of shrinkage and enlargement of filling tail packer.
