Specific embodiment
As shown in figure 3, the double component molten spraying equipment of the utility model first choice embodiment includes device for melt blowing 1, to be mixed
Fiber feeding mechanism 2, needling device 3, web forming device 4.
Device for melt blowing 1 includes spinneret die 11, and spinneret die 11 includes the spray for the lower part for being fixedly mounted on spinneret die 11
Filament plate 12 has several spinneret orifices on spinneret 12.Device for melt blowing 1 is using high velocity, hot air to the spinneret from spinneret die 11
The polymer melt stream that hole squeezes out is drawn, so as to form ultra-fine meltblown fibers.
Fiber feeding mechanism 2 to be mixed includes conveying air passage 21 and wind turbine 22.Conveying air passage 21 has discharge port 21a.When
When wind turbine 22 rotates, generate along conveying air passage 21, blow to the wind of discharge port 21a.Under the action of the forces of the wind, fiber to be mixed
Discharge port 21a is blown to, after discharge port 21a comes out, can be mixed with meltblown fibers, so as to form mixed spray fiber.It is to be mixed
Fiber feeding mechanism includes at least feed roller etc. of a wind turbine, air passage, fiber to be mixed, and wind turbine, air passage are only gived in Fig. 3
A kind of signal, the feed roller of fiber to be mixed etc. is not shown, and there are various in the prior art for fiber feeding mechanism to be mixed
Form, and be not the innovation essence place of the utility model, this will not be repeated here.
Since meltblown fibers and fiber to be mixed are only by the wind-force of vertical direction of device for melt blowing 1 and the water of the generation of wind turbine 22
Square to wind-force mixed, and the wind-force of vertical direction be more than horizontal direction wind-force, therefore, the melt-blown of vertical direction
Fiber will with close to fiber one side to be mixed vertically-supplying air combine to be formed together with brattice, fiber wind in the horizontal direction to be mixed
Under power effect, after discharge port 21a comes out, hit on brattice, and be bonded on meltblown fibers.Due to vertical direction wind speed compared with
Soon, it can scroll down through and move along vertical direction with the fiber to be mixed to come in the horizontal direction.Downward rolling movement
With the wind-force of vertical direction so that the fiber to be mixed that horizontal direction comes is meltblown fiber and encircles to form ring mostly gathers wadding
Piece, the poly- flocculus of ring so that mixed spray fiber is uneven, and horizontal pull resistance is poor.
Needling device 3 is arranged on the lower section of device for melt blowing 1 and fiber feeding mechanism 2 to be mixed, and positioned at web forming device 4
Top namely be arranged in the descent path of mixed spray fiber, in the range of the draw zone of meltblown fibers.In meltblown fibers
In draw zone, such as 0-20 cm sections below spinneret, in this region, meltblown fibers have one also in soft state
Determine stickiness.According to vertical hot wind, horizontal wind and the different influence of environment temperature, the draw zone scope of meltblown fibers may
It changes.Needling device 3 includes a pair of rotatable spiked roller 30, and the direction of rotation of the two spiked rollers 30 is on the contrary, respectively
Positioned at the both sides of mixed spray fiber.Each spiked roller 30 includes roller 31, pin cloth 32, several root thorn pins 33.Pin cloth 32 is wrapped in roller 31
Outer circumferential surface on, pricker 33 is set, and the afterbody of pricker 33 is connected by bindiny mechanism with pin cloth 32 so that often on 32 surface of pin cloth
Root thorn pin 33 can be swung up and down compared with spiked roller 30 and pin cloth 32 around a horizontal axis.Shaft may be employed in bindiny mechanism
Mode realize swinging up and down for pricker 33.Shaft nearby sets position-limit mechanism, for limiting the angle of the swing of pricker 33, preferably
Ground, the angle that pricker 33 is swung up and down are not less than 120 degree.
As shown in figure 4, pricker 33 has the groove 33a of multiple arrangements straggly on the circumferential face, the opening direction of groove 33a
Pin thorn 33b is collectively formed with 33 surface of pricker in the head of pricker 33, groove walls.
When spiked roller 30 rotates at a high speed, also a superhigh speed rotates pricker 33 therewith.When pricker 33 rotates to mixed spray fiber
During place, needle point and pin thorn 33b first needle the poly- flocculus of ring, are sprayed as the pin thorn 33b insertions on pricker circumferential surface are mixed in fiber, pin thorn
The cooperation of 33b and groove 33a, stick the filament of the poly- flocculus of ring (fiber to be mixed), and with these filaments towards melt-blown
The internal motion of fiber.When the rotation of pricker 33 is extremely less than the horizontal plane where spiked roller horizontal rotation shaft, which starts phase
For meltblown fibers toward retraction, the filament in groove 33a therefrom departs from, and glued stays in meltblown fibers.By carrying
The setting of the spiked roller of high density pricker 33, needling process intensive by doing so, repeatedly so that fiber to be mixed is fine in melt-blown
The poly- wadding quilt of ring in dimension table face is needled, and is uniformly mixed in meltblown fibers, and thus obtained mixed spray fiber is more uniform,
And with higher horizontal tearing toughness.
In order to ensure the uniformity of mixed spray fiber, the length of pricker 33 is not less than the thickness of brattice, it is preferable that pricker 33
Length is not less than 10cm.In addition, the linear velocity of spiked roller 30 is greater than the speed that moves down of vertical direction brattice, so can just needle
The poly- fibrefill of ring.
Web forming device 4 includes a pair into net roll 40, is separately positioned on the both sides of mixed spray fiber, and is located at two pins respectively
The lower section of licker-in 30.After the needling process of needling device 3, mixed uniformly mixed spray fiber by the extruding into net roll 40,
Form mixed spray fibrous layer 5.It is uniformly mixed, transverse tensile strength height, is obtained by web forming device 4 mixed due to mixing spray fiber
Spraying fibrous layer 5 also has preferable mixture homogeneity and transverse tensile strength, also, implements needling process before networking, will not
The resilience of fibrous layer 5 is influenced, fibrous layer 5 can be allowed to keep original elastic while improving mixture homogeneity, avoided
It is pierced again into the hand-manipulating of needle after networking, so as to lose resilience.
In other embodiments, the pin cloth of electromagnetism pricker pattern may be employed in needling device 3, i.e., by electromagnetism conducting come
Control pricker 33 extends and retracts.Alternatively, needling device 3 can also use the pin cloth of the stingy flow nozzle pattern of high-speed fine, i.e.,
Extending and retracting for pricker 33 is controlled by air-flow.
Above-mentioned specific embodiment is only described the preferred embodiment of the utility model, and not to this practicality
New protection domain is defined.On the premise of the utility model design conception and scope is not departed from, this field
Those of ordinary skill is according to word description provided by the utility model, attached drawing to made by the technical solution of the utility model
Various modifications, replacement and improvement should all belong to the protection category of the utility model.The scope of protection of the utility model will by right
Ask definite.
