Specific embodiment
As shown in Figures 1 to 7, a kind of two-stage buffering positive type suede is described through let-off mechanism, including the two blocks of wallboards 1 in left and right
It is equipped with suede warp beam 2 on the upside of wallboard, strengthening mechanism 3, upper buffer gear 5 and villus axis counting mechanism 4 are installed on the wallboard,
Wherein upper buffer gear and villus axis counting mechanism are fixed on the wallboard of two sides by bearing block, guarantee axis flexible rotation；It is upper to add
Gu mechanism can be bolted between two wallboards, guarantee that vibration etc. will not be generated when suede warp beam and positive let-off mechanism work
Situation.
The villus axis counting mechanism 4 is between suede warp beam 2 and upper buffer gear 5.
The villus axis counting mechanism includes fixed mechanism 41, hold-down mechanism 42, villus axis 43, bending plate 44, upper connection
Plate 45 is counted close to switch 46.
Wherein fixed mechanism is fixed on wallboard, and villous axis, the villus axis are assembled between two fixed mechanisms
Top is equipped with hold-down mechanism, compresses villus axis by hold-down mechanism, bending plate is equipped on wallboard, the bending plate is connected with
Upper junction plate, the upper junction plate, which is equipped with, to be counted close to switch, and the villus axis is equipped with multiple sensing holes 47, the induction
Hole is matched with close switch is counted.
It is described to count there are two close switch settings.
It counts close to switch upper surface from villus axis distance controlling in 1 ± 0.2mm.
Yarn (L) by suede warp beam to villus axis when, drive its rotation, be then transitioned into pile warp backrest mechanism, suede again
For hair axis in rotation, four sensing holes being staggered positioned at end face circulate through counting close to switch, and each hole connects by counting
It when nearly switch, counts once, represents villus axis and be rotated by 90 °, represent villus axis when two, which count, all counts twice close to switch
Rotation is turned around, and according to diameter of axle size, electric-control system calculates velvet warp yarn displacement, then by counting close to switch feedback signal
It counts and cooperates close to switch and suede through tension sensor, by the publication of electric-control system signal, so that the warp let-off of suede warp beam
It is more accurate.
The optimization design of scheme is wound with flannelette on the villus axis.Flannelette can effectively prevent yarn slippage, more accurately
Calculating yarn displacement, signal is transferred to electric-control system.
The upper buffer gear 5 includes upper fabric guide roll 51, anti-transition deformation iron plate 52, upper elastic plate 53, velvet warp yarn guide
Pipe 54 and other fixed installation components.
Wherein, upper fabric guide roll is mounted between the two blocks of wallboards in left and right by fixed plate, is equipped with fixation on upper fabric guide roll
Frame, the fixed frame are equipped with upper elastic plate, have anti-transition deformation iron plate, velvet warp yarn overtension on the downside of the upper elastic plate
When, it can support elastic plate 11, prevent the excessive damage of its stress.
Velvet warp yarn thread tube 54 is equipped on the upside of upper elastic plate.
Yarn L is then transitioned into lower buffer gear 7 after villus axis counting mechanism, through upper elastic plate (11), in yarn
Under line tension effect, upper elastic plate surrounds upper fabric guide roll center of circle rotational deformation, and at this moment yarn can contact velvet warp yarn thread tube 12, make
Yarn will not all decline regardless of elastic plate deforms, and will increase cladding of the yarn on upper elastic plate 11, increase yarn
Power inductive effects.
The upper buffer gear, upper elastic plate and fixed plate etc. are all common materials, and plate is through Overheating Treatment and part
There is sufficiently resilient and endurance life after bending, can be continued working under 400 revs/min of speed, appliance is at low cost.
Lower buffer gear 7 is additionally provided on the wallboard, the lower buffer gear 7 is in upper 5 lower section of buffer gear.Under described
Buffer gear includes lower elastic plate 71, elastic plate stop mechanism 72, fabric guide roll mounting base 73, lower fabric guide roll 75, lower elastic plate branch
Support square beam 76；The lower elastic plate support square beam is equipped with elastic stopping mechanism, is equipped with lower bullet in the elastic stopping mechanism
Property plate, the lower elastic plate upper end be equipped with fabric guide roll mounting base 73, fabric guide roll mounting base 73 be equipped with lower fabric guide roll 75.It is described
Fabric guide roll gum cover 74 is equipped between fabric guide roll mounting base 73 and lower fabric guide roll 75, the fabric guide roll gum cover 74 is socketed in lower fabric guide roll
On 75.
Yarn crosses menopause tablet at fell after upper buffer gear after lower fabric guide roll, and yarn tension drives lower bullet
Property plate benging rotation, lower elastic plate is through Overheating Treatment, after looped pile reply, can quickly rebound, encounter elastic plate under overtension
Deformation is more, and it is excessive that elastic plate stop mechanism prevents elastic plate from deforming, its curve transition is protected to damage.
The optimization design of scheme, the elastic plate stop mechanism are a long straight panel.
The wallboard is equipped with tension induction mechanism 6, and the upper buffer gear is connected with tension induction mechanism 6, constantly
Incude tension variation.
The tension induction mechanism 6 include tension swing arm 61, tension switch 62 and tension connecting joint bearing 63, it is described on
51 end of fabric guide roll connects tensioned swing arm 61, and tension swing arm 61 is connected with tension switch 62, and tension switch connects tensioned company
Oscillating bearing 63 is connect, tension connecting joint bearing 63 is rotatably connected on wallboard.It is pulled and becomes by yarn tension in upper buffer gear
After shape, certain angular deflection occurs for upper fabric guide roll 51 so that tension swing arm deflects, then drive tension switch,
The deformation of tension connecting joint bearing, tension switch can constantly sense the tension variation of buffer gear.
Wherein, the electronic switch tensometer of model MKY-HTS can be used in tension switch.Tension connecting joint bearing can be adopted
With the oscillating bearing of GEK45ES-2AS.
Working principle, during gigging circle, then buffer is descended in the upper elastic plate deformation of buffer gear upper first
The lower elastic plate of structure deforms, and tension persistently changes, and two-stage elastic plate increases deformation simultaneously, and after current looped pile is casted off, yarn resets,
Tension does not allow to change too much, and elastic plate deforms reset first at present for this, and then upper elastic plate does reset by a small margin and maintains yarn
Line tension waits next pile-weaving.
Mechanism is summarized, suede is through tension induction mechanism and counts close to switch mating reaction, and more acurrate induction suede is through tension
Variation, more acurrate calculating velvet warp yarn sendout.Upper and lower buffer gear acts on simultaneously, and warp tension change degree can be prevented excessive, had
Looped pile flatness at effect protection cloth cover.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
