The invention relates to a
screw conveyor automatic feeding device in a blown film
production line. The
screw conveyor automatic feeding device in the blown film
production line comprises a storage hopper and is characterized in that the
screw conveyor automatic feeding device further comprises a screw conveyor, a motor, a feeding starting
electronic feedback device and a feeding stopping
electronic feedback device, wherein the screw conveyor and the motor are located in the storage hopper and the feeding starting
electronic feedback device and the feeding stopping electronic feedback device are arranged on an extruder hopper, an outer wall is fixedly arranged outside the screw conveyor, a screw conveyor sheave is connected with the lower end of the screw conveyor, one end of a
motor shaft is provided with a motor sheave, and a screw conveyor power driving mechanism is formed by the motor sheave and the screw conveyor sheave through a driving belt; a
thrust bearing assembly is arranged at the lower end of the screw conveyor and a self-aligning bearing
assembly and a pressure bearing
assembly are arranged at the upper end of the screw conveyor. Compared with a negative-pressure feeding device provided with a motor with the same power, the screw conveyor automatic feeding device in the blown film
production line has the advantages that the screw conveyor automatic feeding device is in the feeding state for only 10 minutes per hour, so that
energy consumption is reduced by 75%; dust separation is thoroughly avoided, raw materials are saved, and the problem of environment
pollution is solved; the phenomenon that the
humidity of the raw materials exceeds the standard due to the fact that the raw materials absorb too much
moisture is prevented and the first-pass yield of products is improved to a large extent; allocation of manpower resources can be reduced through
automatic control.
