Detailed description of the invention:
With specific embodiment, the invention will be further described below, sees Fig. 1:
Pressure inductive broken thread detection mechanism, includes head 1, is provided with tension disk 2, chooses on head 1
Line linkage, eedle 5, the thread take-up tension lever 3 of thread take-up tension lever mechanism is between tension disk 2 and eedle 5, at clamp
Being provided with more than one line piece excessively on head 1 between device 2 and eedle 5, suture 4 passes sequentially through clamp
Device 2, excessively line piece, thread take-up tension lever 3 are connected to eedle 5, are provided with foil gauge 6, foil gauge 6 crossing in line piece
Circuit corresponding with in controller electrically connects, and presets the contrast of foil gauge 6 change in resistance amount in described controller
Numerical value, by its change in resistance of controller monitoring:
If breaking, when thread take-up tension lever 3 is in take-up state, suture 4 produces tension force, and foil gauge 6 produces
Raw strain, then controller breaks, and machine normally works；
If breaking, when thread take-up tension lever 3 is in take-up state, suture 4 no-station pole canopy or tension force are little, strain
Sheet 6 maybe should diminish without strain, and the unchanged amount of resistance of foil gauge 6 or variable quantity not up to set numerical value, then
Controller judges to break, and controls machine down.
Being provided with yarn take-up spring 7 on tension disk 2, suture 4 passes sequentially through tension disk 2, yarn take-up spring 7, crosses line
Part, thread take-up tension lever 3 are connected to eedle 5.
