ABSTRACT
Industrial production, there are many places need for powdered or granular solids
flow for accurate measurement and control, with feeding device consisting of
quantitative feeding control system. It is a feeder, flow measurement and control in a
device. At present, production equipment as many quantitative feeding control system
has been widely used in cement, metallurgy, building materials, electric power,
chemical, food, mining, food and other industries. Quantitative feeding in industrial
production is playing an increasingly important role, because of its wide application, if
can improve the feeding system precision, the degree of automation, it has important
practical significance.
Automatic bagging palletizing line is used in the industries of petrochemical,
fertilizer, food processing, and transportation port etc. It can perform bagging and
palletizing automatically for powder and granular materials such as chemical fertilizer,
plastic granules (PP/PE/PVC) and grains etc. It is easy for customers to store, transport
and sale their products. Automatic bagging & palletizing line consists of auto-weighing
bagging machine, auto-bag feed group, sealing system ,bag turn down machine, metal
detector, sorting machine, jet printer and palletizing machine etc. units. Through
programming controller, the whole system process can be automatic controlled. Any
process operation troubles, not enough feeds, bag feeding not due or palletizing not in
time all can be alarmed by sound or light. It has the advantages of simple operation,
reliable and easy maintenance etc.
