Further, described extrusion system is connected to form successively by motor, reductor and screw propulsion system, and screw propulsion system comprises barrel and screw propulsion rod, and screw propulsion rod is connected on reductor, and barrel is connected with blanking chamber by flange.The utility model adopts motor to provide power, by reductor, high-revolving for motor power conversion is become the slow-revving power of high moment of torsion, and the express material fallen from blanking chamber is released by screw propulsion rod.
Further, described paddle device is on support and can radial rotary, and the blade of paddle is Z-shaped.Z-shaped paddle fully can stir the material in hopper, avoids solid accumulation to block and causes producing extremely.
Further, described stirring system is connected with extrusion system by transmission system, provides power to drive the paddle rotary work of stirring system while extrusion system running.The dynamical system of extrusion system acts on stirring system simultaneously, effectively can save system unit, reduces equipment cost, improves the task performance of dynamical system.
Further, described transmission system adopts Chain conveyer, Chain conveyer is nonelastic slip and skidding, and average ratios is accurate, reliable operation, and efficiency is high; Transmitted power is large, and overload capacity is strong, and the transmission size under identical operating mode is little; Required tensile force is little, and the pressure acted on axle is little; Can at high temperature, humidity, many dirt, have in the adverse circumstances such as pollution and work.。
Further, described transmission system comprises sprocket wheel I, driving chain, sprocket wheel II, and sprocket wheel I device is at the tail end of paddle, and sprocket wheel II device, at the end of screw propulsion rod, is connected by driving chain between sprocket wheel I with sprocket wheel II.The structure of transmission system is simple, and transmission efficiency is high, and save system resource, cost of manufacture is low.
Compared with prior art, the utility model advantage is:
Extruder blanking device described in the utility model utilizes mechanical seal and ring flange effectively to improve the sealing of junction, and structural strength is high, and wearability is good, long service life, change without the need to frequent maintenance, reduce maintenance cost, the equipment of guarantee can long-acting stable operation; The utility model structure is simple, and cost of manufacture is low, high financial profit.
