Between described main shaft, use helical gear to carry out gear link, helical gear arc top has arc tooth top.
Described acupuncture mechanism is that upper and lower symmetrical structure sees through middle holder web plate simultaneously and stripping web plate carries out acupuncture.
Described acupuncture mechanism is separately positioned in main spindle box and lower main axis case, and lower main axis case maintains static, and upper main spindle box adopts the lifting of heavy duty lifter, is furnished with hydraulic locking apparatus simultaneously in frame.
Described frame adopts the thick type carbon steel sheet of high-quality to be welded, and tempered stove high-temperature shaping is processed.
Described holder web plate and stripping web plate all adopt alloy-steel plate through heat treatment surface finish hard chrome plating, endoporus Glabrous thorn; Holder web plate, stripping web plate adopt the large height crimping of great circle arc angle to form, and respectively can electrical-controlled lifting, are provided with special-purpose scale and automatic spacing anticollision device, collision-prevention device.
The invention has the beneficial effects as follows:
1. adopt described needling structure frequency can reach the punch frequency of 1800 beats/min, the speed of production of 1～10 m/min, high-yield and high-efficiency guarantees that needing machine vibrations does not occur or swings simultaneously, working stability is efficient;
2. by helical gear camber tooth top, make up morpheme error or the rigging error of two main shafts, make machine operation smooth and easy stable;
3. to thorn, action completes four plates on same machine, has avoided the misdraft to eedle-punched non-wovens, has guaranteed the accuracy of pinprick position, improves the quality of eedle-punched non-wovens;
4. can carry out flexibly apparatus preparing acupuncture pattern according to nonwoven product characteristic and technological requirement, the synchronous while of upper and lower main spindle box is stung or up and down simultaneously to thorn conversion allotment restructuring.
accompanying drawing explanation:
Accompanying drawing 1 is the schematic diagram of invention;
Accompanying drawing 2 is invention acupuncture mechanism front view;
Accompanying drawing 3 is invention acupuncture mechanism side view;
Accompanying drawing 4 is invention gear schematic diagram;
Accompanying drawing 5 is invention general structure schematic diagram.
the specific embodiment:
In order to make juror can the present invention's object, feature and function be had further and be understood, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
As shown in Figure 4, OB is crank, and AB is connecting rod, and B is crankpin center, and A is connecting rod aperture center (or push rod pin center)
According to formula:
The centrifugal force that balance weight produces
cβ=mβ*rβ*ω2
In formula: c β is the centrifugal force that every balance weight produces
M β is balance weight quality
R β is the distance from balance weight barycenter to pivot
The reciprocal inertia force of crank
Pj=-mjRω2cosωt-?mjλR（2ω）2cos2ωt
In formula: Pj is reciprocal inertia force
Mj is reciprocating mass (is eccentric mass+connecting rod tip quality, namely the above quality of push rod bearing pin)
R is eccentric throw
ω t is the angle that crank is turned over by top dead centre
λ is R/L (L is length of connecting rod, i.e. suspension ring centre-to-centre spacing)
The crank up angular velocity varies causing because torque is inhomogeneous is little, be similar to bent axle and do the revolution of zero angle speed, just be equivalent to a reciprocating mass and an eccentric rotating mass, crank throw and length of connecting rod are considered as determining reciprocal inertia force and the centrifugal intertia force of bent axle for this reason.
So be decomposed on crank mechanism under tangential force and normal component of force, take into full account and meet bent axle bearing capacity and shearing force and torsional moment, do the angle of revolution (being the angle that crank is turned over by top dead centre) of a certain proportion of crankshaft rotating centre distance (i.e. the distance from balance weight barycenter to pivot) and connecting rod.
The distance of the pivot of crank mechanism little (be gyrating mass corresponding light) under contrast, so the centrifugal force vectors that produces inferior to tradition (eccentric wheel) mechanism generation centrifugal force vectors.Yet gyrating mass is corresponding to be alleviated (the centrifugal center radius that is gyrating mass is little), mechanism's work reciprocal inertia force is little, improves the optimization to the amount of evoking of mechanism vibrations and coefficient of friction for this reason.
Refer to shown in Fig. 1 to Fig. 2, a kind of acupuncture mechanism of needing machine, mainly comprises main shaft 2, suspension ring 3, push rod 4, guide pin bushing 5; Suspension ring 3 connect push rod 4, on push rod 4, be provided with guide pin bushing 5, main shaft 2 passes in the middle of suspension ring 3, in suspension ring 3 both sides, be provided with the bearing block 6 for fixed main shaft 2 simultaneously, thereby in bearing block 6 both sides, there is weighting distribution wheel 7 simultaneously and form an acupuncture mechanism 1, push rod is passed to the power coming and change torque into, as power, export acting, drive other operating mechanisms and servicing unit work.Adopt thus crankshaft structure to reduce connecting rod ratio, rotary inertia is little, and reciprocal and rotation out-of-balance force greatly reduces, so frequency can reach the punch frequency of 1800 beats/min, the speed of production of 1～10 m/min.
Refer to shown in Fig. 3 to Fig. 4, described main shaft is two and be arranged in parallel, on main shaft 2, be equidistantly distributed with acupuncture mechanism 1, between described main shaft 2, use helical gear 8 to carry out gear link, the arc top of helical gear 8 has arc tooth top 9, and described acupuncture mechanism 1 carries out acupuncture for upper and lower symmetrical structure sees through middle holder web plate 12 simultaneously with stripping web plate 13, and to thorn, action completes four plates on same machine, avoid the misdraft to eedle-punched non-wovens, guaranteed the accuracy of pinprick position.
As preferred technical scheme, described acupuncture mechanism is separately positioned in main spindle box 10 and lower main axis case 11, and lower main axis case 11 maintains static, and upper main spindle box 10 adopts the lifting of heavy duty lifter, is furnished with hydraulic locking apparatus 14 simultaneously in frame; Described frame adopts the thick type carbon steel sheet of high-quality to be welded, and tempered stove high-temperature shaping is processed; Described holder web plate 12 and stripping web plate 13 all adopt alloy-steel plate through heat treatment surface finish hard chrome plating, endoporus Glabrous thorn; Holder web plate 12, stripping web plate 13 adopt the large height crimping of great circle arc angle to form, and respectively can electrical-controlled lifting, are provided with special-purpose scale and automatic spacing anticollision device, collision-prevention device.
certainly, above diagram, only for better embodiment of the present invention, not limits the scope of application of the present invention with this, therefore, everyly in the principle of the invention, make equivalent change and all should be included in protection scope of the present invention.
