Abstract
The utility model relates to a spinneret plate, in particular to a spinneret plate used for weaving cross-shaped carpet yarns. A yarn outlet opening of a spinneret hole adopts a cross-shaped hole; a circular separator separating the four sides of the cross-shaped hole is arranged in the center of the cross-shaped hole, and is integrated with the spinneret plate surface. The spinneret plate has the advantages of simple structure, uniform cross section and shape of formed carpet yarns, good bending resistance and flexibility, and large air capacity as well as good thermal insulation effect for the formed hollow structure.
Description
Technical field
The utility model relates to a kind of spinnerets, especially a kind of spinnerets that is used to spin the cross carpet silk.
Background technology
The cross carpet silk has characteristics such as good flexibility and toughness and has obtained promoting widely and using.But make in the cross carpet silk process at the existing spinnerets spray silk that utilizes, extrude by spinneret orifice in the cooling procedure of back at fiber, tend to because four limits that make the cross carpet silk of expanding with heat and contract with cold produce deformation or adhesion, and cause the cross center of carpet silk to cross the Forming Quality that slightly influences carpet silk.In addition, existing cross carpet silk is owing to the Design of spinneret reason, and feel and flexibility are relatively poor, also can occur problems such as structural stability during use.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of can effectively improve cross carpet silk spray yarn quality, and can form the spinnerets of hollow structure.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cross carpet silk spinnerets that spins, the plate face of spinnerets is provided with spinneret orifice, it is characterized in that: the filament mouth of described spinneret orifice is a cross bore, be provided with the circular barrier that cross bore four limits are separated at the center of cross bore, described barrier and plate face are structure as a whole; By barrier is set, making the carpet silk that pushes out from filament mouth is valvular structure, the hot-air pressure that is positioned at carpet silk middle part is low than the carpet silk outside, make external pressure have certain radial contraction squeezing action power to the outer wall of flap carpet silk, the flap carpet silk is inwardly shunk, form pintongs side fusion docking structure, and form hollow structure at the middle part of carpet silk.In addition, the adjustment space of expanding with heat and contract with cold and providing enough that utilizes barrier that carpet silk is produced in the final molding process has effectively prevented from can guarantee the uniformity and the stability of product quality simultaneously owing to the malformation of expanding with heat and contract with cold and causing.And the integrative-structure of barrier and plate face designs, and then simplifies the processing technology of spinnerets, has guaranteed the precision of spinneret orifice size.
In order to make filament mouth keep certain extrusion pressure, guarantee molding effect, further: described filament mouth is the undergauge structure.
Have enough molding times in order to ensure the fiber that squeezes out at filament mouth, more further: the contraction angle [alpha] in the described filament mouth undergauge structure is 30 °-90 °.
The utility model is simple in structure, the carpet silk cross sectional shape homogeneous of moulding, and fold resistance and flexible better and form hollow structure contains that air capacity is big, high insulating effect.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model spinneret pore structure schematic diagram.
Fig. 3 is the utility model cross bore structural representation.
Among the figure: 1. plate face 2. spinneret orifices 3. cross bore 4. barriers
The specific embodiment
As Fig. 1, Fig. 2, a kind of cross carpet silk spinnerets that spins shown in Figure 3, the plate face 1 of spinnerets is provided with spinneret orifice 2, the filament mouth of described spinneret orifice 2 is a cross bore 3, is provided with circular barrier 4 at the center of cross bore 3, and barrier 4 separates cross bore four limits.Described filament mouth is the undergauge structure, and shrinking angle [alpha] is 50 °, and the depth D of filament mouth is 2mm.Described barrier 4 is structure as a whole with plate face 1.
The utility model is simple in structure, and institute's carpet silk of making is tactical rule and stablizing not only, and can become hollow structure at the center, has further increased the flexibility of carpet silk, has also improved the heat insulation effect of carpet silk.
