Description
Technical Field
The utility model relates to a spinneret, in particular to simple structure, convenient to use, the cooling effect is good, fast, difficult jam, and moulding effect is good, and the shaping degree is high, improves the product quality, improves work efficiency's spinneret.
Background
The spinneret plate is used for converting a viscous-flow-state polymer melt or solution into a thin flow with a specific cross section through micropores, and solidifying the thin flow through a solidification medium such as air or a solidification bath to form filaments; different specifications, shapes, hole patterns, materials and the like are provided according to different types and specifications of the fibers; the spinneret plate works at higher temperature and pressure; pressure resistance, corrosion resistance and sufficient mechanical strength are required; in the spinning production process, high-temperature melt is extruded out of a spinneret plate body under certain pressure, densely distributed high-temperature melt trickle is formed through spinneret holes, the temperature of the melt trickle is very high, and the melt trickle needs to be uniformly cooled and form stable pre-drawn yarns with certain crystallinity and pre-orientation degree in a certain spinning range and a short time through a circular blowing cooling device; because the diameter of the spinneret plate is large, the number of tows is large, cooling air is difficult to penetrate through peripheral tows which are densely distributed layer by layer to reach the middle part of the spinneret plate, and the tows in the middle part of the spinneret plate cannot meet the process requirements due to cooling, so that spinning is difficult, and the product quality is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a simple structure, convenient to use, and the cooling effect is good, fast, difficult jam, and moulding effect is good, and the shaping degree is high, improves the product quality, improves work efficiency's spinneret.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a spinneret plate, comprising: a spinneret plate body; a circular hole is formed in the center of the upper end of the spinneret plate body; a plurality of strip-shaped grooves are uniformly distributed at the upper end of the spinneret plate body around the round hole; two groups of feeding holes are arranged in the strip-shaped groove; each group of feed holes comprises: two feed ports; the lower end of the spinneret plate is provided with discharge holes between each group of feed holes; the two feeding holes are communicated with the discharging hole to form a V-shaped channel.
Preferably, both sides of the upper end surface of the spinneret plate body are provided with first grooves, and both sides of the lower end surface of the spinneret plate body are provided with second grooves; the first groove is symmetrical to the second groove.
Preferably, the front end and the rear end of the spinneret plate body are both provided with a fixing hole.
