Description
Technical field
The present invention relates to a kind of device that is used to carry out burn out detection on the two-for-one twister that is arranged on.
Background technology
In the prior art; two-for-one twister twist with the fingers around and need pass through bobbin respectively when sending yarn; spindle turntable; feed carrier; and then yarn is wound up on the coiler device; and walk around in the journey at sth. made by twisting; because what be subjected to each parts touches wearing and tearing and self tension force effect; the phenomenon that yarn can break; the motor of two-for-one twister still remains in operation behind broken string; make spindle turntable and coiler device under the driving of motor, dally, both can cause the waste of use cost, the yarn that easily makes disconnection again by machine lead around; cause trouble to industrial production; so in the operating process of twisting with the fingers winding yarns, also need operating personnel to observe maintenance usually, use cumbersome.
Summary of the invention
The object of the invention provides a kind of burn out detection mechanism of two-for-one twister, and it can detect when yarn breaks automatically.
Technical scheme of the present invention is: a kind of burn out detection mechanism of two-for-one twister, it comprises falling the pin location-plate, be arranged on to insulation the needle tubing that falls on the described pin location-plate that falls, be inserted in the pin that falls in the inner chamber of the described needle tubing that falls slidably, has electric-conductor on the described pin location-plate that falls, described fall be provided with insulator between needle tubing and the electric-conductor, it axially has the guiding breach sidewall upper edge of the described needle tubing that falls, the top of the described pin that falls has cantilever arm, this cantilever arm passes the outside that the guiding breach extends to needle tubing, described cantilever arm has at least two operating positions, under first operating position, described cantilever arm is positioned at the upside of electric-conductor, is in electric insulating state between cantilever arm and the electric-conductor; Under second operating position, described cantilever arm contacts with electric-conductor, is in status of electrically connecting between the two.
Be set with magnetic block in the top inner chamber of the described needle tubing that falls.
The top of the described needle tubing that falls and fall and be provided with cross-over block between the pin location-plate.
The present invention compared with prior art, has following advantage: when practical application, yarn is passed the downside of cantilever arm and the pin that falls is formed support, yarn by normal twist with the fingers around the time, cantilever arm is supported by yarn and is in first operating position, fall needle tubing and fall to being subjected to the obstruct of insulator between the pin location-plate makes circuit disconnect; When yarn breaks, the pin that falls promptly loses support force and makes cantilever arm drop to second operating position, make cantilever arm contact and turning circuit with the pin location-plate that falls, can show power on signal by indicator lamp or miscellaneous equipment, make the staff promptly can observe a long way off, examine maintenance and need not to look at two-for-one twister.

The specific embodiment
Shown in accompanying drawing 3-accompanying drawing 5, a kind of burn out detection mechanism of two-for-one twister, it comprises falling pin location-plate 6, the needle tubing 7 that falls, be inserted in the pin 12 that falls in the inner chamber of the described needle tubing 7 that falls slidably, is set with magnetic block 13 in the top inner chamber of the described needle tubing 7 that falls.
Has electric-conductor 14 on the described pin location-plate 6 that falls, the bottom of the described needle tubing 7 that falls is passed in the electric-conductor 14, and fall to being provided with insulator 15 between needle tubing 7 and the electric-conductor 14, the top of the described needle tubing 7 that falls and fall to being provided with cross-over block 16 between the pin location-plate 6 described.
It axially has guiding breach 8 the sidewall upper edge of the described needle tubing 7 that falls, the top of the described pin 12 that falls has cantilever arm 9, this cantilever arm 9 passes the outside that guiding breach 8 extends to needle tubing 7, described cantilever arm 9 has at least two operating positions, under first operating position, described cantilever arm 9 is positioned at the upside of electric-conductor 14, and under second operating position, described cantilever arm 9 descends and contacts with electric-conductor 14.
Shown in accompanying drawing 1-accompanying drawing 2, the present invention is installed on the frame 11 of two-for-one twister and uses, also be provided with spindle turntable 2 and coiler device 10 on frame 11, be provided with bobbin 1 on the spindle turntable 2 rotatably, the present invention is promptly between bobbin 1 and coiler device 10.The yarn wound packages is provided with yarn-guide tube 5 in the bobbin 1 in bobbin 1, have yarn outlet 3 on the spindle turntable 2, and when real work, yarn 4 passes yarn-guide tube 5 backs and stretches out from yarn outlet 3, is batched by coiler device 10 through behind the present invention.Spindle turntable 2 is rotation at a high speed under the driving of motor, make yarn 4 rotate at a high speed around bobbin 1 under the drive of spindle turntable 2, thereby the sth. made by twisting of realization yarn 4 is around operation.
