Abstract

The present invention relates to a kind of melt-blown header structure of melt blowing machine, 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, the 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; Orthogonal first flow and the second runner is formed between flow distributor and matrix; Flow distributor has the air-flow inlet hole, the first flow-guiding channel and the second flow-guiding channel that are communicated with successively, and the sidepiece of flow distributor also has oblique through hole, and oblique through hole is communicated with first flow, the second flow-guiding channel and the second flow passage.Structure of the present invention is comparatively simple, by adopting dual-heated structure and specific hot-air runner, realizing, to the homogeneous heating of meltblown beam, not only reducing cost, also improving the quality of product.

Description

The melt-blown header structure of melt blowing machine
Technical field
The present invention relates to field of textile machinery, particularly melt blowing machine.
Background technology
Melt blowing machine adopts meltblown that resin slicer or resin particle are made 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, the uniformity of melt blown non-woven and die design, manufactures substantial connection.The structure of existing meltblown beam is comparatively complicated, and cost is higher, and the heating of melt-blown head is uneven, causes the product quality that processes not high enough.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provide a kind of melt-blown header structure of melt blowing machine, it has the advantages that structure is simple, easy to loading and unloading and cost is low.
In order to solve the problem, the present invention adopts following scheme:
A kind of melt-blown header structure of melt blowing machine, 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, the 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; Orthogonal first flow and the second runner is formed between flow distributor and matrix; Flow distributor has the air-flow inlet hole, the first flow-guiding channel and the second flow-guiding channel that are communicated with successively, and the sidepiece of flow distributor also has oblique through hole, and oblique through hole is communicated with first flow, the second flow-guiding channel and the second flow passage.
Further technical scheme is:
Second flow-guiding channel relative centre runner 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, realizing, to the homogeneous heating of meltblown beam, not only reducing cost, also improving the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
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 between upper and lower die body 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, first heat block 2 is affixed with the side of matrix 1 and flow distributor 3, and the second heat block 7 is affixed with the opposite side of flow distributor 3; Orthogonal first flow 4 and the second runner 5 is formed between flow distributor 3 and matrix 1; Flow distributor 3 has air-flow inlet hole 31, first flow-guiding channel 32 and the second flow-guiding channel 34 that are communicated with successively, the sidepiece of flow distributor 3 also has oblique through hole 33, oblique through hole 33 is communicated with first flow 4, second flow-guiding channel 34 is communicated with the second runner 5, and logical 34 relative centre stream 6 roads, road of the second water conservancy diversion are obliquely installed.Its effect is conducive to jet-impingement on 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 heat matrix and flow distributor respectively, solidify to prevent polymer melt; Hot-air flows into the first flow-guiding channel 32 from air-flow inlet hole 31, a part flows into first flow 4 from oblique through hole 33 and flows out from the second runner 5, another part flows out from the second flow-guiding channel 34, the air-flow that second runner 5 flows out and the air-flow that the second flow-guiding channel 34 flows out converge, second flow-guiding channel 34 relative centre runner 6 is obliquely installed, make jet-impingement to polymer melt also improves to spray pulling force, polymer melt is stretched, finally by cooling device (not shown), the polymer stretched is cooled, finally form fiber web.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
