One, foreword screw extruder is cable bag glue, play the production trade such as bottle, plastic film and tubal material main facility, its action is to will get together fat section, melt, pressurization, squeeze next piece. When screw extruder works normally, the basis produces the demand of craft, the crowded outlet pressure of its screw should keep constant, in order to assure crowded stability giving an amount. To achieve this requirement, the extruder of common country uses dc timing or slippery poor timing. In pattern of afore-mentioned two kinds of timing, dc timing precision is tall, but dc machine is strict to environmental requirement, fault rate is high; Stability of electric machinery of slippery poor timing is poor, efficiency is low, and power consumption is tall. 2, frequency control implement the characteristic develops as the high speed of contemporary electron technology, because communication transducer uses personal computer technology, because this has timing range wide, function all ready, function reliable, versatility is strong, use handy and agile wait for a lot of advantage. Get be used extensively on the timing control to electromotor, its exceedingly good section report effect more get the general welcome of the user. 3, transform program, pursue as follows: Get together fat piece lean self-prossessed from enter screw extruder into makings mouth, extruder passes frequency control implement control electric machinery of common squirrel cage to drive screw roll, get together fat piece edge snail chamfer moves ahead. Screw coat canister installs phone heating element, pass quantity of heat get together fat piece; In the meantime, inside screw extruder get together fat piece can produce certain quantity of heat because of grinding to be squashed, get together fat piece be heated is fused, be compressed by extruder the fuse-element that has constant pressure, squeeze from exit go out to get certain outside factor when screw extruder, when waiting for an influence like temperature, the viscosity of its interior fuse-element produces change, bring about wave motion of extruder outlet pressure then, change of this one pressure is measured so that the pressure signal of adjuster of elder brother PID and set compares by pressure sensor, the output frequency that will control transducer via imitate signal is being outputted after PID operation, adjust namely the rotate speed of electric machinery. Adjust the change of screw rotate speed, achieve stable extruder outlet pressure and the goal that push a volume thereby. Assured the quality of the product leisurely, improved manufacturing efficiency, also saved many charge of electricity at the same time. CNC Milling CNC Machining
