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 that extruder goes out to manage the Length Control field, particularly relates to a kind of extruder and goes out to manage the Length Control device.
Background technology
The length of tube control device that goes out on the existing extruder has two kinds: lead limit switch control and the control of rolling wheel encoding device length.Their weak point: lead limit switch causes the pipe length location inaccurate in the long-term rear spring easy fatigue of using.The rolling wheel encoding device is to drive the encoder rotation through tubing to realize the control to pipe length, but has tubing to cause the pipe length location to be forbidden with the wheel slip phenomenon in actual use.
Summary of the invention
In order to overcome the deficiency of prior art, the present invention provides a kind of and regulates more convenient, more reliable, the more firm extruder in position when producing different size tubing and go out to manage Length Control device and control method thereof.
A kind of extruder goes out to manage the Length Control device, comprises support, and the trigger switch that is installed in the support lower end goes out to manage the Length Control device and is fixed on the fixed head on the frame whole with being used for, and said trigger switch is used to detect tubing to be passed through, and sends the Pipe Cutting control signal.
Said trigger switch comprises proximity transducer and swing gate, and said swing gate and said proximity transducer flexibly connect, and said proximity transducer is used for sending the Pipe Cutting signal according to the amplitude of preset control value and swing gate swing.
Said proximity transducer is the inductance type proximity transducer.
Said support upper end is provided with big or small tube regulator, is used to realize the positioning control to different pipe fittings.
A kind of extruder goes out to manage the Length Control method, comprises proximity transducer, the swing gate that is connected with proximity transducer that is installed in the support lower end and is used for going out to manage the Length Control device and being fixed on the fixed head on the frame whole, comprising:
1) extruder goes out the length of tube control device and is installed on the frame;
2) tubing promotes said swing gate through the said swing gate that goes out the length of tube control device;
3) said proximity transducer judges whether that according to the amplitude of fluctuation of said preset value and swing gate needs carry out the Pipe Cutting operation: if the amplitude of said swing gate swing less than preset value, is not then sent out place's Pipe Cutting signal; If the amplitude of said swing gate swing greater than preset value, is then sent out place's Pipe Cutting signal;
Also comprise the big or small tube regulator that is arranged at said support upper end, said step 1) and 2) between also comprise, through said big or small tube regulator, according to the specification of tubing, the preset value of regulating said proximity transducer with go out to manage positioning control.
Compared with prior art, the invention has the advantages that:
Adjusting is more convenient, more reliable when producing different size tubing, the position is more firm.Proximity transducer does not contact with other objects, therefore as long as under environment provided He under the temperature conditions, use, not influenced by external force; Do not damage hardware, can use always, do not have this parameter of life-span; Have high responsiveness, high reliability simultaneously, locate accurate, non-maintaining.
