Description
Technical field
The utility model relates to a kind of spinning appts for melt spraying non-woven fabrics.
Background technique
Material Chinese is polybutylene terephthalate (PBT), abbreviation saturated polyester, due to good fluidity, crystallization rate
Fastly, it is suitable for production superfine fibre class non-woven fabrics.
It in the production process of non-woven fabrics, needs PBT material melt-out spinning, and forms non-woven fabrics after winding cooling.It is existing
Some spinning appts, spinneret is uneven, the quality of the non-woven fabrics of strong influence production.
Summary of the invention
The purpose of the utility model is to provide the spinning appts that a kind of spinneret is uniformly used for melt spraying non-woven fabrics.
In order to achieve the above objectives, the technical solution adopted in the utility model is:
A kind of spinning appts for melt spraying non-woven fabrics, for spraying the PBT raw material of melting, the spinning appts include shell
Body, the feed inlet for being passed through the PBT raw material on the shell, be connected on the shell for the shell
Be passed through in vivo the air inlet pipe of compressed air, on the shell for spraying the spinneret unit of the PBT raw material, it is described into
There are two tracheaes, and is located at the opposite two sides of the shell.
Preferably, two air inlet pipe are respectively communicated with air compressor.
Preferably, the spinneret unit include spinneret, several spinneret orifices for being opened on the spinneret.
It is further preferred that several filament arrays are arranged on the spinneret.
It is further preferred that the aperture of the spinneret orifice is 0.2 ~ 0.4mm.
It is further preferred that the spinning appts further include the distribution plate being disposed in the housing, the distribution plate is located at
Between the spinneret and the feed inlet.
It is further preferred that several dispensing orifices are offered on the distribution plate, several dispensing orifice array arrangements
In on the distribution plate.
It is further preferred that the spinning appts further include the heating unit on the spinneret.
It is further preferred that the heating unit is the heater strip for being attached at the spinneret face.
Due to the application of the above technical scheme, the utility model has the advantage that this is practical new compared with prior art
A kind of spinning appts for melt spraying non-woven fabrics of type are improved by the way that two air inlet pipe are respectively arranged on the opposite two sides of shell
The uniformity of compressed air, greatly improves the effect of spinneret in shell.

Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
Join as shown in figure 1 to 3, a kind of spinning appts for melt spraying non-woven fabrics, for spraying the PBT raw material of melting, spinneret
Device include shell 1, the feed inlet 2 for being passed through PBT raw material on shell 1, be connected on shell 1 for shell
The air inlet pipe 3 of compressed air, the spinneret unit 4 for being used to spray PBT raw material on shell 1 are passed through in 1, air inlet pipe 3 has two
It is a, and it is located at the opposite two sides of shell 1.Herein, two air inlet pipe 3 are respectively communicated with air compressor 5.
By the way that two air inlet pipe 3 are respectively arranged on the opposite two sides of shell 1, the uniform of compressed air in shell 1 is improved
Property, greatly improve the effect of spinneret.
In the present embodiment, spinneret unit 4 includes spinneret 4a, several spinneret orifice 4b being opened on spinneret 4a, if
For dry spinneret orifice 4b array arrangement on spinneret 4a, the aperture of spinneret orifice 4b is 0.2 ~ 0.4mm.
In the present embodiment, spinning appts further include the distribution plate 6 in the shell 1, distribution plate 6 be located at spinneret 4a with
Between feed inlet 2.Several dispensing orifices 7 are offered on distribution plate 6, several 7 array arrangements of dispensing orifice are on distribution plate 6.Herein,
Distribution plate 6 is round panel.By setting distribution plate 6, the PBT liquid after melting is enabled to flow through flow speed stability after dispensing orifice 7,
So as to spray at slave spinneret 4a more evenly, the uniformity of spinneret is further improved.
The spinning appts further include the heating unit 8 on spinneret 4a.Here, heating unit 8 is to be attached at spinneret
The heater strip on the surface plate 4a.By the setting of heating unit 8, enables the PBT liquid after melting to continue to keep temperature, prevent it
It is solidified in advance because temperature reduces, thus the quality of non-woven fabrics made of influencing.
Illustrate the course of work of lower the present embodiment in detail below: when work starts, PBT liquid after melting is from feed inlet 2
Into shell 1, two air inlet pipe 3 are passed through compressed air into shell 1 respectively at this time, so that the air pressure in shell 1 increases, PBT
Liquid uniformly sprays under the action of internal and external pressure difference from spinneret orifice 4b.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
