Abstract
The invention provides a sizing type spinning nozzle. The sizing type spinning nozzle comprises a spinning nozzle body. The spinning nozzle body is divided into an extrusion pipe, a constant-speed peeling pipe and a separating pipe from top to bottom. The separating pipe is rotationally connected with the constant-speed peeling pipe. Melt is extruded out of the extrusion pipe, the constant-speed peeling pipe is internally and coaxially provided with a spiral scraper driven by a motor to rotate, a scraper is arranged on the inner wall of the separating pipe, and the internal diameter of the spiral scraper is equal to that of the movement track of the scraper and is matched with the diameter of the melt. Absorbing holes for absorbing abundant melt are evenly distributed in the inner wall of the separating pipe. According to the sizing type spinning nozzle, after being extruded out of the extrusion pipe, the melt swells, the spiral scraper scrapes the abundant melt away and enables the abundant melt to enter gaps in the spiral scraper, the abundant melt enters the separating pipe through rotation of the spiral scraper, and the separating pipe further processes the melt so that the diameter of the melt can be evener.
Description
Art
The present invention relates to apparatus for melt spinning field, especially, is a kind of sizing formula spinning head.
Background technology
One of main manufacturing process of melt spinning chemical fibre, is called for short melt-spun.Synthetic fiber principal item terylene, polyamide fibre, polypropylene fibre etc. all adopt melt-spun to produce.The main feature of melt-spun be winding speed high, do not need solvent and precipitating agent, equipment is simple, and technological process is short.Fusing point forms the fibre-forming polymer of thermally-stabilised melt lower than decomposition temperature, melting, and this method all can be adopted to be shaped.
Melt is by spray silk keyhole formation melt stream.Thread diameter there will be swelling going out to spray silk aperture place, this is because caused by during elastic melt ejection spray silk aperture, instantaneous pressure suddenly disappears.Different polymer aperture degrees of expansion is different.Polyester, polyamide melt are under normal spinning condition, and dieswell is than below 1.5.Buoyancy effect is polypropylene more significantly.Dieswell is often the root that melt becomes filament diameter inequality.In production, normal employing increase is sprayed silk hole diameter, draw ratio (opening length and diameter ratio) and is improved the measures such as melt temperature and reduces to swell ratio, to prevent melt fracture.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of sizing formula spinning head, this sizing formula spinning head can produce the spinning of uniform diameter.
The technical solution adopted for the present invention to solve the technical problems is:
This sizing formula spinning head comprises spinning head, described spinning head is divided into extruding pipe from top to bottom, at the uniform velocity peels off pipe and separator tube, described separator tube is rotatably connected with described pipe of at the uniform velocity peeling off, melt extrusion in described extruding pipe, described inner coaxial tube of at the uniform velocity peeling off is provided with helical form scraper, described spiral scraper is driven by motor and rotates, described separator tube inwall is provided with scraper, the internal diameter of described helical form scraper is identical with the internal diameter of described scraper movement locus and close with the diameter compatible of described melt, described separator tube inwall is evenly equipped with the sucker absorbing unnecessary melt.
As preferably, described scraper eccentric setting, the eccentric angle of described scraper is greater than 10 degree and is less than 30 degree.
As preferably, described helical form scraper to scrape speed identical with the extruded velocity of described melt.
The invention has the advantages that:
After described extruding pipe melt extrusion, melt swells phenomenon, unnecessary melt strikes off and makes unnecessary melt enter the gap of described helical form scraper by described helical form scraper, and entering described separator tube by the rotation of helical form scraper, described separator tube makes its diameter more even to melt processing further.

Fig. 3 is the schematic cross-section of this sizing formula spinning head separator tube.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1, Fig. 2 and Fig. 3, this sizing formula spinning head comprises spinning head, described spinning head is divided into extruding pipe 100 from top to bottom, at the uniform velocity peel off pipe 200 and separator tube 300, described separator tube 300 is rotatably connected with described pipe 200 of at the uniform velocity peeling off, melt extrusion 10 in described extruding pipe 100, described at the uniform velocity stripping in pipe 200 is coaxially arranged with helical form scraper 210, described helical form scraper 210 is driven by motor and rotates, described separator tube 300 inwall is provided with scraper 310, the internal diameter of described helical form scraper 210 is identical with the internal diameter of described scraper 310 movement locus and close with the diameter compatible of described melt 10, described separator tube 300 inwall is evenly equipped with the sucker 320 absorbing unnecessary melt.
Consult Fig. 3, described scraper eccentric setting, the eccentric angle of described scraper 310 is greater than 10 degree and is less than 30 degree, ensures the shearing dynamics of scraper 310 for unnecessary melt, ensures the mobility of the melt after being sheared simultaneously.
Above-mentioned sizing formula spinning head, scraping of described helical form scraper 210 is fast identical with the extruded velocity of described melt 10, and the unnecessary melt that described helical form scraper 210 is struck off no longer extrudes the melt 10 of Engage of standard diameter again
The working method of above-mentioned sizing formula spinning head and principle:
Consult Fig. 1, after described extruding pipe 100 melt extrusion 10, melt 10 swells phenomenon, unnecessary melt 10 strikes off and makes unnecessary melt 10 enter the gap of described helical form scraper 210 by described helical form scraper 210, and enter described separator tube 300 by the rotation of helical form scraper 210, described separator tube 300 makes its diameter more even to melt 10 processing further, the scraper 210 simultaneously rotated by from the unnecessary melt 10 at the uniform velocity peeling off pipe 200 centrifugal enter sucker 320 on separator tube 300 inwall absorb.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
