A kind of wire breakage detector
Technical field:
The present invention relates to the technical fields of detection device, more specifically to a kind of wire breakage detector.
Background technique:
Current mechanical end break self-stop needle (automatic stop bar) is widely used in doubling as wire breakage detector, twists thread, again
On twirl, principle is: yarn pass through automatic stop needle (or automatic stop bar is pressed on yarn), when yarn broken automatic stop needle (automatic stop bar) by
In self gravitation effect to whereabouts, lower backwardness encounters a parts, this parts promotes spool bracket to lift, and spool lifts discord
Groove drum contact does not just turn, to play the role of automatic stop.But the present parts to match with end break self-stop needle (automatic stop bar) often go out
Existing failure, when end break self-stop needle (automatic stop bar) falls, parts fail to lift spool.(the automatic stop of end break self-stop needle is used simultaneously
Bar) it can manage it and have a problem that, after end break self-stop needle (automatic stop bar) whereabouts spool is lifted, spool can be because inertia continues after lifting
Rotation.
Summary of the invention:
The purpose of the present invention is to the deficiencies of the prior art, and provide a kind of wire breakage detector, are able to maintain
While yarn is tensioned, it can quickly judge to have troubles, to realize equipment automatic stop.
To achieve the above object, The technical solution adopted by the invention is as follows:

On plate, the other end lower tensioning wheel is hinged with by bearing, pillar;Divide on the upper side edge of lower nutted rod and the lower side of upper nutted rod
It is not fixed with upper magnet item and lower magnet strip, upper magnet item and lower magnet strip are attracting;
Side on mounting base close to lower nutted rod lower side is fixed with approach switch sensor, mounting base upper end
It forms fulcrum on front end face, has directive wheel by bearing hinge connection on fulcrum, drive is fixed on the rear end face of mounting base lower end
Dynamic motor, the front end face sleeve that the shaft of driving motor passes through mounting base are fixed with unilateral bearing, and unilateral bearing upper sleeve is solid
Surely there is reel;The string holes opposite with directive wheel and reel is separately formed on the upper and lower end face of the detection box.
Preferably, the quadrangle of the mounting base forms waist-shaped hole.
Preferably, it is fixed with cushion block on the rear end face of the mounting base quadrangle, it is opposite to form waist-shaped hole on cushion block
Perforation;Mounting base is bolted on detection box.
Preferably, the quadrangle of the detection box forms stud set, and cover is bolted on detection box.
Preferably, the center of the directive wheel and reel is distributed on the vertical center line of mounting base.
Preferably, the thickness of the thickness of the upper nutted rod and lower nutted rod is equal, the thickness of upper tensioning wheel and lower tensioning
The thickness of wheel is equal, and the sum of thickness of upper nutted rod, upper tensioning wheel and mounting base is less than the depth of detection box.
The beneficial effects of the present invention are: its structure is simple, is able to achieve and the yarn in it is disposed to be in tensioning state always,
And can quickly judge to have troubles, to realize equipment automatic stop.

Specific embodiment:
Embodiment: as shown in Fig. 1 to 4, a kind of wire breakage detector, including cover 1 and detection box 2, it detects and is installed in box 2
There is the mounting base 3 of rectangle, the quadrangle of mounting base 3 forms mounting hole 31, and the center of 3 rear end face of mounting base, which is fixed with, to be connect
Touch sensor 8, the probe of touch sensor 8 expose the front end face of mounting base 3, the peace of the upper and lower side of touch sensor 8
Upper nutted rod 4 and lower nutted rod 6 that 3 front end face of bottom plate is equipped with alternating expression are filled, one end of upper nutted rod 4 is hinged on close to installation
On the mounting base 3 of 3 side side of bottom plate, the other end upper tensioning wheel 5, one end of lower nutted rod 6 be hinged with by bearing, pillar
It is hinged on the mounting base 3 close to 3 other side side of mounting base, the other end by bearing, pillar is hinged with lower tensioning wheel
7;Upper magnet item 9 and lower magnet strip 10, upper magnetic are respectively fixed on the upper side edge of lower nutted rod 6 and the lower side of upper nutted rod 4
Body item 9 and lower magnet strip 10 are attracting;
Side on mounting base 3 close to lower 6 lower side of nutted rod is fixed with approach switch sensor 11, mounting base 3
It forms fulcrum 32 on the front end face of upper end, has directive wheel 12, the rear end of 3 lower end of mounting base by bearing hinge connection on fulcrum 32
Driving motor 15 is fixed on face, the front end face sleeve that the shaft of driving motor 15 passes through mounting base 3 is fixed with unilateral bearing
13,13 upper sleeve of unilateral bearing is fixed with reel 14;It has been separately formed and directive wheel on the upper and lower end face of the detection box 2
12 and the opposite string holes 21 of reel 14.
Preferably, the quadrangle of the mounting base 3 forms waist-shaped hole 31.
