Abstract
The invention provides a spinneret plate for a melt spinning device. The spinneret plate comprises a main body and is characterized in that a set of guide holes are formed on a feeding side of the main body; the tail ends of the guide holes are communicated with spinneret holes on a discharging side of the main body; a heat-insulating sleeve is arranged on the exterior of the main body; the axial direction of the heat-insulating sleeve extends along the discharging side of the main body; the extending length of the heat-insulating sleeve is 1.5-2.5 times of the axial length of the main body. The spinneret plate for the melt spinning device can effectively prevent the spinneret plate from being blocked under a horizontal blowing cooling environment and the work is stable and reliable.
Description
Technical field：
The present invention relates to a kind of melt spinning device spinneret, belong to synthetic fiber spinning technical field.
Background technology：
Melt spinning method is divided into polymerization, co-blended spinning method, core-sheath spinning method again, is a kind of conventional spinning process, from
Screw extruder melt out is sent to spinneret assembly through dosing pump.The latter is by groups such as drainage screen, distribution plate and spinnerets
Become, its effect is the impurity removing in melt, makes melt equably deliver to spinneret.Existing spinneret is with heat-resisting, corrosion resistant
The stainless steel material of erosion is made, and the aperture on face is arranged according to certain rules, and aperture is usually 0.2～0.5 millimeter.Melt passes through spray
Keyhole formation melt stream on filament plate.Melt stream is subject to the effect of cold air to cool and solidify after spraying.Thread and surrounding
The heat exchange of medium is mainly carried out with convection type with conducting.The temperature of melt stream progressively declines in cooling procedure, viscosity
Then improve constantly, and when viscosity brings up to certain marginal value winding tension and has been insufficient to allow fiber to continue to attenuate, just reach solid
Change point.Solidification length refers to length from spray webbing aperture to solidification point for the melt stream, and this is the key area that fibre structure is formed.
Typically by the way of air-cooled, cooling blowing mode divides horizontal blowing and blow-through wind two to the type of cooling of existing thread
Kind.The wind direction of horizontal blowing is vertical with fiber, straight blowing direction and fibers parallel, typically adopts horizontal blowing more.The fibre of different cultivars
Tie up and the requirement difference to cooling for the different fibers, spinning polyester and polyamide cord line fiber are then often below spinning head and cold
But above room, setting heater, to drop low-fiber rate of cooling, makes as-spun fibre even structure, tensile property is good.Spinning
During coarse sliver fiber processed, (as monofilament) Chang Yishui is coolant, so that fiber is cooled down rapidly.And existing cooling wind is directly horizontal blows
Mode makes spinneret be affected to lead to the spacing rapid cooling in die orifice exit by cold wind, easily causes spinneret and blocks up
Plug, impact is normal to be produced.
Content of the invention：
The purpose of the present invention is to provide a kind of melt spinning device spinneret for above-mentioned problem, can be prevented effectively from
The situation that spinneret is blocked in the environment of horizontal quenching, stable and reliable in work.
Above-mentioned purpose is realized by following technical scheme：
Melt spinning device spinneret, including body, the feed side of described body is provided with one group of guide hole, described guide hole
End connection be located at body exit side spinneret orifice, described body exterior is provided with a muff, described insulation
The exit side elongation axially along body of set, the length of its elongation is 1.5-2.5 times of the described axial length of body.
Described melt spinning device spinneret, described guide hole from feed side toward exit side include successively cylindrical section and
Surface blending section, described cylindrical section is 5 with the aspect ratio of described surface blending section：1.
Described melt spinning device spinneret, described guide hole is in that concentric circles arrange.
Described melt spinning device spinneret, described guide hole assumes diamond in shape arrangement.
Beneficial effect：
The body exterior that the outside of the present invention is provided with spinneret is provided with muff, and effectively prevent cooling, wind is directly horizontal blows
Mode make spinneret be affected to lead to the spacing rapid cooling in die orifice exit by cold wind, easily cause spinneret block up
Plug, the normal problem producing of impact.
The guide hole of the present invention includes cylindrical section and surface blending section from feed side successively toward exit side, described cylindrical section with
The aspect ratio of described surface blending section is 5：1, increase melt potential energy and mobility, reduce the elasticity that melt obtains in inlet region
Can, reduce the contact surface of net and spray webbing back before plate, reduce the probability that dead angle occurs as far as possible, also shorten melt simultaneously
The time of staying, avoid the generation with carbonization of degrading.
Brief description：
Fig. 1 is the structural representation of the present invention.
In figure：1st, body；2nd, guide hole；3rd, spinneret orifice；4th, muff.
Specific embodiment：
Embodiment 1：
As shown in figure 1, the melt spinning device spinneret of the present embodiment, including body 1, the feed side of described body is arranged
There is one group of guide hole 2, the end connection of described guide hole is located at the spinneret orifice 3 of the exit side of body, described body exterior is arranged
There is a muff 4, the exit side axially along body of described muff extends, the length of its elongation is described body
1.5-2.5 times of axial length.
Melt spinning device spinneret described in the present embodiment, described guide hole wraps toward exit side successively from feed side
Include cylindrical section and surface blending section, described cylindrical section is 5 with the aspect ratio of described surface blending section：1.
Described melt spinning device spinneret, described guide hole is in that concentric circles arrange.
Embodiment 2：
The present embodiment is with the difference of embodiment 1, the melt spinning device spinneret described in the present embodiment, described
Guide hole assumes diamond in shape arrangement.
Technological means disclosed in the present invention program are not limited only to the technological means disclosed in above-mentioned technological means, also include
The technical scheme being made up of above technical characteristic equivalent.The unaccomplished matter of the present invention, belongs to those skilled in the art's
Common knowledge.
