Abstract
The utility model relates to a spinneret plate comprising a spinneret plate body, wherein spinneret orifices are formed in the spinneret plate body, an annular ventilating path, taking the center of the spinneret plate as the circle center, is arranged on the spinneret plate body on which at least one linear ventilating path is further arranged, one end of the linear ventilating path is communicated with the annular ventilating path, and the other end of the linear ventilating path is communicated with the exterior of the spinneret plate body. By adopting the spinneret plate, high temperature melt spayed by the spinneret plate can be wholly and uniformly cooled in a certain spinning line within a specified period of time to meet technological requirements and form stable pre-drafting silk with certain crystallinity and certain pre-orientation degree, so that the spinning effect is better.
Description
Technical field
The utility model relates to the fiber production apparatus technical field, refers more particularly to a kind of spinnerets.
Background technology
The structure of the spinnerets that is used for spinning that present stage generally uses comprises: the spinnerets body evenly is densely covered with spinneret orifice on the body.In the spinning production process, high-temperature fusant is extruded the spinnerets body under certain pressure, form densely covered high-temperature fusant thread through spinneret orifice, these melt thread temperature are very high, generally between 290～325 ℃, through the ring cold wind blower, need spin in journey and very short time certain, evenly cool off and form the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree; Because the diameter of spinnerets is bigger, tow is many, and cooling air is difficult to pass densely covered layer by layer peripheral tow and arrives the spinnerets middle part, and the tow that is positioned at the spinnerets middle part can not reach technological requirement because of cooling, and causes difficulty in spinning, influences product quality.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can make whole tow all cool off the spinnerets that reaches technological requirement.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of spinnerets, comprise: the spinnerets body, the spinnerets body is provided with spinneret orifice, it is the annular air channel in the center of circle that described spinnerets body is provided with the spinnerets center, also be provided with at least one straight line ventilating duct on the spinnerets body, an end of straight line ventilating duct is connected with annular air channel, and the other end of straight line ventilating duct is connected with the outside of spinnerets body.
Described spinnerets body is provided with four straight line ventilating ducts, and four straight line ventilating ducts evenly distribute along the hoop of spinnerets body.
The beneficial effects of the utility model are: above-mentioned spinnerets, can make high-temperature fusant that spinnerets sprays in official hour and certain spinning on the journey, all cooling reaches technological requirement and forms the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree uniformly, thereby makes spinning effect better.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, spinnerets body, 2, spinneret orifice, 3, annular air channel, 4, the straight line ventilating duct.
The specific embodiment
Below by specific embodiment a kind of spinnerets described in the utility model is described in further detail.
As shown in Figure 1, a kind of spinnerets, comprise: spinnerets body 1, spinnerets body 1 is provided with spinneret orifice 2, it is the annular air channel 3 in the center of circle that described spinnerets body 1 is provided with the spinnerets center, also is provided with 4, four straight line ventilating ducts 4 of four straight line ventilating ducts on the spinnerets body 1 and evenly distributes along the hoop of spinnerets body 1, one end of every straight line ventilating duct 4 is connected with annular air channel 3, and the other end of straight line ventilating duct 4 is connected with the outside of spinnerets body 1.
Above-mentioned spinnerets, it is by arranging straight line ventilating duct 4 and annular air channel 3 at spinnerets body 1, because no spinneret orifices and being interconnected in straight line ventilating duct 4 and annular air channel 3 zones, just there is not tow to stop the current of cooling air yet, cooling air can enter into the spinnerets middle part by the spinnerets periphery by the air channel, thereby the tow that is positioned at the spinnerets middle part also can be cooled off reach technological requirement, whole tow that spinnerets is sprayed all cool off and reach requirements, thereby make spinning effect better.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
