Abstract
A kind of spinneret orifice replaced type spinneret, including spinneret plate body, variable spinneret orifice；Trident Type ventilating duct is provided on the spinneret plate body, the air duct of Trident Type ventilating duct is semicircle, and Trident Type ventilating duct is uniformly divided into three equal parts centered on the center of spinneret plate body, spinneret plate body；The variable spinneret orifice sets gradually four, five, six hole locations in the plate face of the spinneret plate body of trisection.Spinneret in the utility model, structure is simple, and installation and replacement are convenient, effectively raises the efficiency of experimental branch line.Spinneret in the utility model further reduced the production cost of enterprise, bring better economic benefit to enterprise.
Description
Technical field
The utility model belongs to field of chemical fiber production equipment, and in particular to a kind of spinneret orifice replaced type spinneret.
Background technique
The effect of spinneret is by the high polymer molten or solution of viscous state, and being transformed by micropore has particular cross section shape
Thread is solidified to form strand by setting medium such as air or coagulating bath.By the classification and specification difference of fiber, have different
Specification, shape, pass, material etc..Spinneret works under higher temperature and pressure.It is required that pressure-resistant, corrosion-resistant and enough
Mechanical strength.In spinning production process, high-temperature fusant is extruded spinnerette body under a certain pressure, is formed by spinneret orifice close
The high-temperature fusant thread of cloth, these melt stream temperature are very high, by ring blower cooling device, need in certain spinning journey and very
In the short time, uniform cooling simultaneously forms the stable preliminary draft silk with certain crystallinity and pre-orientation degree；Due to spinneret
Be relatively large in diameter, tow is more, and cooling wind is difficult to reach in the middle part of spinneret across peripheral tow densely covered layer by layer, is located in spinneret
The tow in portion can lead to difficulty in spinning because cooling be not achieved technique requirement, influence product quality.
But the spinneret channel design of existing spinneret is single, generally circular hole channel, the lower end in circular hole channel pass through cone
Shape closes up and from discharge hole wire vent, and by the quick moulding of lower end toper closing in, moulding is ineffective in the spinneret channel of this class formation,
Forming degree is insufficient.When carrying out spinning to different demands fiber product, need to replace spinneret, but common spinneret
It is mostly integrally formed, needs to replace entire spinneret in replacement, thus bring the wasting of resources, increase enterprise
Production cost.
Utility model content
The purpose of this utility model is that aiming at the shortcomings in the prior art, providing a kind of spinneret orifice replaced type spinneret.
It in order to realize the present invention, is realized using following technical scheme: a kind of spinneret orifice replaced type spinneret, including spinneret
Plate plate body, variable spinneret orifice；Trident Type ventilating duct is provided on the spinneret plate body, the air duct of Trident Type ventilating duct is semicircle
Shape, Trident Type ventilating duct are uniformly divided into three equal parts centered on the center of spinneret plate body, spinneret plate body；The variable spray
Wire hole sets gradually four, five, six hole locations in the plate face of the spinneret plate body of trisection.
Further, the spinneret plate body and variable spinneret orifice junction are equipped with link slot, and link slot is arranged in spinneret
In the plate body of plate body.
Further, the two sides of the variable spinneret orifice are equipped with fixed pin.
The utility model has the advantages that the spinneret in (1) the utility model, structure is simple, and installation and replacement are convenient, effectively raising
The efficiency of fibre production.
(2) spinneret in the utility model further reduced the production cost of enterprise, bring preferably to enterprise
Economic benefit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic diagram that can be changed spinneret orifice in the utility model.
Fig. 3 is the schematic diagram of link slot on spinneret plate body in the utility model.
Specific embodiment
Embodiment: a kind of spinneret orifice replaced type spinneret, including spinneret plate body 1, variable spinneret orifice 2；The spinneret
Trident Type ventilating duct 3 is provided on plate body 1, the air duct of Trident Type ventilating duct 3 is semicircle, and Trident Type ventilating duct 3 is with spinneret
Centered on the center of plate body 1, spinneret plate body 1 is uniformly divided into three equal parts；Spinneret of the variable spinneret orifice 2 in trisection
Four, five, six hole locations are set gradually in the plate face of plate body 1.
The spinneret plate body 1 is equipped with link slot 4 with variable 2 junction of spinneret orifice, and link slot 4 is arranged in spinneret plate body
In 1 plate body.
The two sides of the variable spinneret orifice 2 are equipped with fixed pin 5.
Claims (3)
