Background technology
Chinese patent ZL200520047626.4 discloses a kind of spinning manifold of spun-bond process non-interlaced fabric equipment; It comprises melt inlet, some grades of conveyance conduits, and each grade conveyance conduit is provided with the plurality of conduits outlet, and the outlet of each grade conveyance conduit sets gradually the next stage conveyance conduit; The pipe outlet screen pack of the conveyance conduit of level of the end; Be the perforated distributor that is distributed with the hole that differs in size below the screen pack, melt finally by evenly flowing out in the hole of perforated distributor, gets into spinnerets.Melt can make melt evenly flow out the entering spinnerets through the pipe outlet shunting of some grades of settings through the perforated distributor that is distributed with the hole that differs in size.
The weak point of above-mentioned prior art is: aborning, usually can run into the problem of line clogging, blocking position is generally in pipeline corner.If processing is untimely, will cause material carbonization in the whole distribution duct, work causes very big difficulty to pipe-dredging, even causes whole spinning manifold to scrap.Secondly, the distributing uniformity of melt is relatively poor, and reason is: 1, owing to existing pipeline processing technology, internal diameter of the pipeline deviation at the same level is bigger, can't guarantee the load height homogeneous of each pipeline.2, its pipeline branch that adopts is mixed and is had the problem that is difficult to reach homogeneous.
It is highly even how to provide a kind of melt to distribute, and simple in structure and difficult the obstruction even if the manifold of when stopping up, being convenient to clear up is used the spinning die head, is the technical problem that this area will solve.
The utility model content
The technical problem that the utility model will solve provide a kind of simple in structure, melt distributing uniformity better, convenient processing and installation, be difficult for taking place stopping up and even if the manifold of when stopping up, being convenient to clear up mediation is used the spinning die head.
In order to solve the problems of the technologies described above; The utility model provides a kind of manifold to use the spinning die head; Comprise: the die head body of a pair of symmetrical configuration; And only therein the central upper end of a die head inner body wall is provided with melt inlet, on the inwall of this die head body and in the bilateral symmetry of said melt inlet, is distributed with to be suitable for the multistage delivery chute that is connected with said melt inlet in use, and delivery chute openings at two ends at different levels outlet down links to each other with the central portion of the delivery chute of next stage; The outlet lower end at final stage delivery chute two ends is provided with screen pack, distribution plate and spinnerets up and down successively.
Particularly, screen pack is the above filter screens of 50 orders, is beneficial to the impurity in the filtering melt.Be evenly distributed with through hole on the said distribution plate.
Particularly; Said delivery chute is half slot or deep-slotted chip breaker; The sectional area of delivery chute reduces from top to bottom step by step, and the sectional area of the delivery chute of upper level is not less than the twice of the delivery chute sectional area of next stage, so that the melt hydraulic pressure in the delivery chute at the same level keeps is basic identical.
Further, the outlet of described final stage delivery chute is evenly distributed, and is beneficial to the even discharging of melt.
Be distributed with a plurality of installing holes that are used for connecting described a pair of die head body and the sealing of realization face on the inwall of said die head body through bolt.
For preventing to stop up, the corner of said delivery chute is curved, the inner wall smooth of delivery chute.
The technique scheme of the utility model is compared prior art and had the following advantages: the manifold of the utility model is used the spinning die head; On the inwall of die head body, be provided for the multistage delivery chute of melt conveying, convenient processing and installation, the difficult advantage that obstruction takes place; Even if when taking place to stop up,,, be difficult for taking place the situation that the die head body is scrapped because of obstruction just can clear up mediation as long as take the said a pair of die head body that is oppositely arranged apart; Said delivery chute processing dimension is easy to control, and machining accuracy is high, and each grade distribution is one-to-two, and the outlet of final stage delivery chute is evenly distributed, and can guarantee the even discharging of melt.
