Abstract
The invention relates to a melt spraying nozzle structure for a melt spraying machine. The melt spraying nozzle structure comprises moulds which are vertically symmetrical arranged; a central runner is arranged between upper and lower moulds; each of the moulds comprises a base, a heating device and an air-flow distributing device; the heating device comprises a first heating block and a second heating block; the first heating block is fixedly connected with the base and one side of the air-flow distributing device; the second heating block is fixedly connected with the other side of the air-flow distributing device; a first runner and a second runner which are vertical to each other are formed between the air-flow distributing device and the base; the air-flow distributing device is provided with an air-flow inlet, a first guiding channel and a second guiding channel which are communicated with each other in turn; an inclined through hole is arranged on a lateral part of the air-flow distributing device; the inclined through hole is communicated with the first runner; and the second guiding channel is communicated with the second runner. The melt spraying nozzle structure is simpler. A dual heating structure and a specific hot air runner are adopted, so that the uniform heating for a melt spraying mould is realized, the cost is lowered and the quality of products is increased.
Description
Technical field
The present invention 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.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, is studied and is improved, and a kind of header structure that melts and sprays of melt blowing machine is provided, and it has characteristics simple in structure, easy to loading and unloading and that cost is low.
In order to address the above problem, the present invention adopts following scheme:
A kind of melt blowing machine melt and spray header structure, comprise upper and lower symmetrically arranged die body, there is center flow channels between upper and lower die body, 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; Form orthogonal first flow and the second runner between flow distributor and matrix; Flow distributor has air-flow inlet hole, the first flow-guiding channel and the second flow-guiding channel be 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 invention is:
Structure of the present invention 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.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, the present invention includes upper and lower symmetrically arranged die body, there is center flow channels 6 between upper and lower die body, 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 be 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 logical 34 relative centers, road of the second water conservancy diversion are flowed 6 roads and are obliquely installed.Its effect is to be conducive to jet-impingement to polymer melt.
When the present invention works, 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 are heated matrix and flow distributor respectively, to prevent polymer melt, solidify; 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 the injection pulling force to polymer melt, polymer melt is stretched, finally by the cooling device (not shown), the polymer stretched is carried out coolingly, finally form fiber web.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that, without prejudice to spirit of the present invention, the present invention can do any type of modification to the restriction of invention.
