Description
Technical field
The utility model belongs to fuse spinning field, in particular to a kind of high-strength ventilative staple fiber spinneret.
Background technique
Staple fiber is also known as staple, is that chemical fibre long-fiber bundle is cut off or breaks into and be equivalent to various natural fibers
The fiber of length.Polyester staple fiber plays an important role in the daily production and life of people.Spinneret is that polyester is short
Important component in fiber production process, the effect of spinneret are to turn the high polymer molten or solution of viscous state by micropore
Become the thread with particular cross section shape, is solidified to form strand by setting medium such as air or coagulating bath.According to fiber
Classification is different, and the specification of spinneret, shape, pass, material are also different, and spinneret works under higher temperature and pressure,
It asks pressure-resistant, corrosion-resistant and there is enough mechanical strengths.In the prior art, polyester staple fiber higher for intensity is insufficient
Place is: the permeability of staple fiber is often poor.
Utility model content
The purpose of the utility model is to provide a kind of high-strength ventilative staple fiber spinnerets, can guarantee polyester staple fiber
While intensity, increase the permeability of staple fiber, so that manufactured staple fiber performance is more preferable.
Purpose of the utility model is realized as follows: a kind of high-strength ventilative staple fiber spinneret, including round spinneret,
For spinneret through several spinneret orifices for enclosing and being circumferentially evenly spaced on are offered from upside to downside, the spinneret orifice includes center
Reinforcement part and annular profile portion, between the center reinforcement part and annular profile portion be equipped with it is several be arranged radially it is radially connected
Portion, the circumferential spacing between adjacent radial interconnecting piece is equal, and there are spinning air hole, the annulars between adjacent radial interconnecting piece
Peripheral part includes several arc spacer bodies, is equipped with circumferential interconnecting piece between adjacent arc spacer body, adjacent arc spacer body it
Between circumferential spacing it is equal.
When utility model works, the high polymer molten of viscous state is led to the upside of spinneret, melt passes through each spinneret
Hole is transformed into the spinneret orifice thread being made of center reinforcement part, radially connected portion and annular profile portion, such as empty by setting medium
Gas or coagulating bath are solidified to form strand.Compared with prior art, the utility model has the beneficial effects that: center reinforcement part is protected
The intensity of strand is demonstrate,proved, annular profile portion further enhances the intensity of strand；The ventilative of staple fiber can be improved in spinning air hole
Performance；While guaranteeing polyester staple fiber intensity, increase the permeability of staple fiber, so that manufactured staple fiber performance is more
It is good.
The flow area of spinneret orifice center reinforcement part is on the upside of spinneret as a further improvement of the utility model,
Successively decrease on the downside of to spinneret.High polymer molten is flowed on the upside of spinneret on the downside of spinneret, and the cross-sectional area of melt is gradually reduced,
Ensure that there is no holes in melt, it is ensured that the high intensity of center reinforcement part.
In order to guarantee the bonding strength between radially connected portion and arc spacer body, width of the spinning aperture to interconnecting piece
It spends and is incremented by from one end close to center reinforcement part to one end close to annular profile portion.
The upside of the spinneret is equipped with the upper locating ring of annular as a further improvement of the utility model, spinneret
Top is covered with upper cover body, and upper cover body inner circumferential fits with upper locating ring periphery, and the downside of spinneret is equipped with the lower locating ring of annular,
The lower section of spinneret is equipped with lower cover, and lower cover inner circumferential fits with lower locating ring periphery.When without using spinneret, upper cover body and
Lower cover shelters from the spinneret orifice on spinneret, prevents dust, impurity from entering spinneret orifice, the quality for the strand for influencing out.
In order to save the flow of high polymer molten, avoid waste, the radial width of the circumferential direction interconnecting piece is less than arc point
The radial width of spacer.
Detailed description of the invention
Fig. 1 is the top cross-sectional view of spinneret orifice.
Fig. 2 is the lower cross section figure of spinneret orifice.
Fig. 3 is the sectional view along AA of Fig. 2.
Fig. 4 is the top view of spinneret.
Fig. 5 is the structural schematic diagram of spinneret, upper cover body and lower cover.
Wherein, 1 spinneret, 2 spinneret orifices, 201 center reinforcement parts, 202 annular profile portions, 202a arc spacer body, 203 diameters
To interconnecting piece, 204 circumferential interconnecting pieces, 3 spinning air holes, locating ring on 4,5 upper cover bodies, 6 lower locating rings, 7 lower covers.
Specific embodiment
It as shown in Figs. 1-5, is a kind of high-strength ventilative staple fiber spinneret, including round spinneret 1, spinneret 1 is from upside
Run through to downside and offer several spinneret orifices 2 for enclosing and being circumferentially evenly spaced on, spinneret orifice 2 includes center reinforcement part 201 and ring
Shape peripheral part 202 is equipped with several radially connected portions 203 being arranged radially between center reinforcement part 201 and annular profile portion 202,
Circumferential spacing between adjacent radial interconnecting piece 203 is equal, and there are spinning air hole 3, annulars between adjacent radial interconnecting piece 203
Peripheral part 202 includes several arc spacer body 202a, and circumferential interconnecting piece 204, phase are equipped between adjacent arc spacer body 202a
