Abstract
The invention provides an outlet pipe fixed length control device for an extruder. The device comprises a bracket, a trigger switch and a fixing plate, wherein the trigger switch is arranged at the lower end of the bracket; the fixing plate is used for fixing the entire outlet pipe fixed length control device on a frame; and the trigger switch is used for detecting the passage of pipes and transmitting a pipe cutting control signal. Due to the adoption of the device, adjustment is more convenient and more reliable and the position is more stable during the production of pipes of different specifications. A proximity detector is not contacted with other objects, so that the proximity detector can be used eternally once the proximity detector is in specified environments and at specified temperatures and is not influenced by the external force and hardware is not damaged. The device has the advantages of high response, high reliability, accurate positioning and freeness from maintenance.
Description
Technical field
The present invention is applicable to extruder and goes out to manage Length Control field, particularly relates to a kind of fixed length control device for extending pipes of extruder.
Background technology
The length of tube control device that goes out on existing extruder has two kinds: lead limit switch is controlled and rolling wheel encoding device length is controlled.Their weak point: lead limit switch causes pipe length location inaccurate in the long-term easy fatigue of rear spring of using.Rolling wheel encoding device is to drive encoder rotation to realize the control to pipe length by tubing, but has in actual use tubing to cause pipe length location to be forbidden with wheel slip phenomenon.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of regulate while producing different size tubing more convenient, more reliable, more firm fixed length control device for extending pipes of extruder and the control method thereof in position.
, comprise support, be arranged on the trigger switch of support lower end and for going out to manage fixed length control device and be fixed on the fixed head in frame whole, described trigger switch passes through for detection of tubing, and sends Pipe Cutting control signal.
Described trigger switch comprises proximity transducer and swing gate, and described swing gate is flexibly connected with described proximity transducer, and described proximity transducer is for sending Pipe Cutting signal according to the amplitude of preset control value and swing gate swing.
Described proximity transducer is inductance type proximity transducer.
Described support upper end is provided with big or small tube regulator, for realizing the positioning control to different pipe fittings.
Go out to manage a Length Control method, comprise and be arranged on the proximity transducer of support lower end, the swing gate being connected with proximity transducer and for going out to manage fixed length control device and be fixed on the fixed head in frame whole, comprise:
1) extruder goes out length of tube control device and is installed in frame;
2) tubing, by the described swing gate that goes out length of tube control device, promotes described swing gate;
3) described proximity transducer judges whether to carry out Pipe Cutting operation according to the amplitude of fluctuation of described preset value and swing gate: if the amplitude that described swing gate swings is less than preset value, do not send out place's Pipe Cutting signal; If the amplitude that described swing gate swings is greater than preset value, send out place's Pipe Cutting signal;
Also comprise the big or small tube regulator that is arranged at described support upper end, described step 1) and 2) between also comprise, by described big or small tube regulator, according to the specification of tubing, the preset value that regulates described proximity transducer with go out to manage positioning control.
Compared with prior art, the invention has the advantages that:
While producing different size tubing, regulate more convenient, more reliable, position is more firm.Proximity transducer not with other object contacts, therefore as long as use under the environment of regulation and under temperature conditions, not affected by external force, do not damage hardware, can use always, there is no this parameter of life-span, there is high responsiveness, high reliability, registration, non-maintaining simultaneously.
Accompanying drawing explanation
Fig. 1 is the structure chart of fixed length control device for extending pipes of extruder of the present invention;
