Abstract
The invention discloses a spinneret for one-step forming of a screen drum. The spinneret comprises a spinneret core, a driving device, a fixing seat and a melt pipe, and is characterized in that the spinneret core is fixed on the fixing seat via a bearing, the spinneret core is hermetically connected with the melt pipe through a pipe rotating joint, a spinneret plate is arranged at the front end of the spinneret core, and at leas one circle of spinneret holes in circular arrangement are formed in the spinneret plate. The spinneret can rotate, and one circle of the spinneret holes arrayed into a ring shape are formed on the spinneret, so that the spinneret can produce fabric of a screen drum structure by one-step forming; meanwhile, newborn strands just extruded from the spinneret holes have moderate viscosity to enable filaments to be adhered mutually, and accordingly the formed screen drum structure is more stable.
Description
Technical field
The invention belongs to synthetic fiber spinning field, relate in particular to a kind of net cylinder one-shot forming spinning head.
Background technology
Spinning head is for producing continuously the integral part of the melt spinning device of composite yarn.Spinning head makes that polymer melt is squeezed into many wire long filaments becomes possibility, and long filament some strands is combined to form composite yarn.Therefore such spinning head conventionally has the spinnerets that comprises a plurality of spinneret orifices on their bottom side, and polymer melt is extruded by this nozzle plate to squeeze out long filament.Subsequently, in the line treating apparatus of long filament after spinning head, be combined into multifilament threads, and be solidified and again process, be finally wound in bobbin, also do not have at present a kind of spinning head will after polymer melt ejection, directly be made into one-time formed net cylinder.
Summary of the invention
In order to overcome this problem, the invention provides a kind of net cylinder one-shot forming spinning head, for the nascent tow of just having extruded being added to certain twist forms a complete net barrel structure.
Technical scheme of the present invention is to provide a kind of net cylinder one-shot forming spinning head, comprise: melt pipe, spinning head core body and holder, it is characterized in that, described spinning head core body is fixed on holder with bearing, pipeline swivel joint be tightly connected described spinning head core body and described melt pipe, described spinning head core body front end is provided with spinnerets, and described spinnerets is provided with the spinneret orifice of at least one circle annular array.
As preferred version, described drive unit can drive described spinning head core body to rotate on described bearing.
As preferred version, described pipeline swivel joint rotation and the dead in line of described spinning head core body rotation.
As preferred version, described spinnerets is circular dull and stereotyped, and described spinneret orifice runs through described spinnerets circular slab face.
As preferred version, described spinneret orifice is arranged in annular on described spinnerets, and described annular is concentric with described spinnerets.
As preferred version, described spinneret orifice is at interval of the spinneret orifice setting of staggering, and the distance at interval of two described spinneret orifices of a spinneret orifice apart from the center of circle equates.
As preferred version, described spinneret orifice is arranged in the face of cylinder vertical in described spinnerets, the axis symmetry of adjacent spinneret orifice be 15 ° of-45 ° of angles with vertical vertical line.
As preferred version, the spinneret orifice on described spinnerets rearranges two annulars, and described annular is concentric with circular described spinnerets.
Net cylinder one-shot forming spinning head of the present invention, spinning head rotation can be rotated, which is provided with the spinneret orifice that a circle is arranged in annular, make spinning head of the present invention can one-time formedly produce the fabric of net barrel structure, utilize the nascent tow of just extruding from spinneret orifice to have appropriate viscosity simultaneously and make adhesion mutually between silk, the net barrel structure of formation is more firm.

The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of embodiment net cylinder one-shot forming spinning head of the present invention, comprise spinning head core body 1, drive unit 2, holder 3 and melt pipe 4, spinning head core body 1 is communicated with melt pipe 4, spinning head core body 1 use bearing 8 is fixed on holder 3, pipeline swivel joint 7 be tightly connected spinning head core body 1 and melt pipe 4, spinning head core body 1 front end is provided with spinnerets 5, spinnerets 5 is provided with the spinneret orifice 6 of a circle annular array, drive unit 2 can drive spinning head core body 1 to rotate on bearing 8, pipeline swivel joint 7 rotations and the 1 rotation dead in line of spinning head core body.
Pipeline swivel joint 7 can make the device of pipeline swivel joint 7 opposite sides unaffected when spinning head rotates, and the melt in melt pipe 4 and spinning head core body 1 can not be affected yet; Bearing 8 can rotate freely spinning head core body 1 under the driving of drive unit 2.
When the present invention works, polymer melt is pressed into melt pipe 4 and enters in spinning head, after spinnerets 5, be extruded spinning head, drive unit 2 drives spinning head core body 1 to rotate on bearing 8, coaxial pipeline swivel joint 7 is also followed rotation, polymer melt after spinnerets 5 can not be subject to the impact of spinning head core body 1 rotation, in some spinneret orifices 6 that polymer melt is provided with from spinnerets 5, be extruded and form nascent tow, the spinneret orifice 6 being provided with due to spinnerets 5 is arranged in annular, nascent tow also forms annular, in continuous extrusion, nascent tow forms wound packages, place, crosspoint mutual between silk can be inter-adhesive, make net cylinder 9 structures more stable, rotation due to spinning head, nascent tow is followed rotation and is coupled with certain twist.
The axis symmetry of adjacent spinneret orifice 6 be 30 ° of angles with vertical vertical line, the silk thread on net cylinder 9 is ejected and along both direction, extends respectively afterwards, makes the angle of the silk thread combination on net cylinder 9 with abundant.
In another kind of embodiment of the present invention, spinneret orifice 6 on spinnerets 5 is arranged in two annulars, during work, just can form small one and large one two net cylinders 9, small net tube is inserted in small net tube, form double-barrel structure, the invention is not restricted to spinnerets 5 and be provided with the annular that one or two spinneret orifice 6 forms, spinneret orifice forms annular and is at least one.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
