Abstract
The utility model relates to a melt-blown head structure of a melt-blown machine. The melt-blown head structure comprises an upper mould and a lower mould which are symmetrically arranged; a central runner is arranged between the upper mould and the lower mould; each of the moulds comprises a base, a heating device and an air-flow distributing device; each heating device comprises a first heating block and a second heating block; each first heating block is fixedly connected with the corresponding base and one side of the corresponding air-flow distributing device; each second heating block is fixedly connected with the other side of the corresponding air-flow distributing device; a first runner and a second runner which are vertical to each other are formed between each air-flow distributing device and the corresponding base; each air-flow distributing device is provided with an air-flow inlet, a first flow guide channel and a second flow guide channel which are communicated in sequence; an inclined through hole is further formed in the lateral part of each air-flow distributing device; each inclined through hole is communicated with the corresponding first runner; each second flow guide channel is communicated with the corresponding second runner. The melt-blown head structure is relatively simple in structure, uniform heating for a melt-blown mould head is realized by adopting dual heating structures and a specific hot air runner, so that the cost is reduced, and the product quality is also improved.
Description
Technical field
The utility model relates to field of textile machinery, particularly melt blowing machine.
Background technology
Melt blowing machine is to adopt meltblown that resin slicer or resin particle are made to fibroreticulate one-step method to become cloth equipment, and made fibre web is generally used for the aspects such as filtering material, oil absorption material, hygienic material.Meltblown beam is the critical component of melt blowing machine, and the uniformity of melt blown non-woven and die design, manufacture have substantial connection.The structure of existing meltblown beam is comparatively complicated, and cost is higher, and it is inhomogeneous to melt and spray the heating of head, causes the product quality that processes not high enough.
Utility model content
The applicant, for the above-mentioned shortcoming of prior art, studies and improves, and a kind of header structure that melts and sprays of melt blowing machine is provided, and it has feature simple in structure, easy to loading and unloading and that cost is low.
In order to address the above problem, the utility model adopts following scheme:
A kind of melt blowing machine melt and spray header structure, comprise upper and lower symmetrically arranged die body, between upper and lower die body, there is center flow channels, die body comprises matrix, heater and flow distributor, heater comprises the first heat block and the second heat block, one side of the first heat block and matrix and flow distributor is affixed, and the opposite side of the second heat block and flow distributor is affixed; Between flow distributor and matrix, form orthogonal first flow and the second runner; Flow distributor has air-flow inlet hole, the first flow-guiding channel and the second flow-guiding channel being communicated with successively, and the sidepiece of flow distributor also has oblique through hole, and tiltedly through hole is communicated with first flow, and the second flow-guiding channel is communicated with the second runner.
Further technical scheme is:
The relative center flow channels of the second flow-guiding channel is obliquely installed.
Technique effect of the present utility model is:
The utility model structure is comparatively simple, by adopting dual-heated structure and specific hot-air runner, realizes the homogeneous heating to meltblown beam, has not only reduced cost, has also improved the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
See Fig. 1, the utility model comprises upper and lower symmetrically arranged die body, between upper and lower die body, there is center flow channels 6, die body comprises matrix 1, heater and flow distributor 3, heater comprises the first heat block 2 and the second heat block 7, the first heat block 2 is affixed with a side of matrix 1 and flow distributor 3, and the second heat block 7 is affixed with the opposite side of flow distributor 3; 1 of flow distributor 3 and matrix form orthogonal first flow 4 and the second runner 5; Flow distributor 3 has air-flow inlet hole 31, the first flow-guiding channel 32 and the second flow-guiding channel 34 being communicated with successively, the sidepiece of flow distributor 3 also has oblique through hole 33, tiltedly through hole 33 is communicated with first flow 4, the second flow-guiding channel 34 is communicated with the second runner 5, and the second relative center, water conservancy diversion Tong34 road is flowed 6 roads and is obliquely installed.Its effect is to be conducive to jet-impingement to polymer melt.
During the utility model work, polymer melt flows into from the center flow channels 6 between upper and lower die body, and the first heat block 2 and the second heat block 7 heat matrix and flow distributor respectively, to prevent that polymer melt from solidifying; Hot-air flows into the first flow-guiding channel 32 from air-flow inlet hole 31, a part flows into first flow 4 and flows out from the second runner 5 from oblique through hole 33, another part flows out from the second flow-guiding channel 34, the air-flow that the air-flow that the second runner 5 flows out and the second flow-guiding channel 34 flow out converges, the relative center flow channels 6 of the second flow-guiding channel 34 is obliquely installed, make jet-impingement also improve injection pulling force to polymer melt, polymer melt is stretched, finally by cooling device (not shown), the polymer having stretched is carried out coolingly, finally form fiber web.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
