Description
Art
The utility model relates to spinning technical field of mechanical equipment, especially, is the device that a kind of magnetic pressure type control fuse swells.
Background technology
One of main manufacturing process of 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 the keyhole formation melt stream on spinnerets, due to the rheological characteristic of melt, the shape of the section shape and size after melt extrusion and micropore is made to produce difference, i.e. extrusion swelling phenomenon, extrusion swelling is phenomenon common in extrusion molding, the shape and size of extruded product are changed, and having the Quality and yield of spinning very important affects picture, and different polymer aperture degrees of expansion is different.Polyester, polyamide melt are under normal spinning condition, and dieswell is than below 1.5.Therefore to the accurate control of extruded product, the quality of spinning is just determined.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of magnetic pressure control swollen melt spinning apparatus, and the swollen melt spinning apparatus of this magnetic pressure control can prevent the spinning generation dieswell phenomenon extruded.
The utility model solves the technical scheme that its technical problem adopts:
The swollen melt spinning apparatus of this magnetic pressure control comprises body, described body root connects melt extrusion device, the head of described body forms the spinning nozzle of ejection melt, a circle conductive ring is provided with inside the root of described body, described conductive ring connects a pole of an electrostatic generator, the wall of described body is provided with the first magnetic sheet and the second magnetic sheet that arrange along body axisymmetrical, described first magnetic sheet is spirally along body distribution formation first magnetic sheet array, described second magnetic sheet is spirally along body distribution formation second magnetic sheet array, the polarity that described symmetrically arranged first magnetic sheet is relative with the second magnetic sheet forms magnetic field at described tubular body on the contrary, often pair is symmetrical arranged on the inboard wall of tube body between the first magnetic sheet and the second magnetic sheet and is all provided with corresponding ventilation recess, the centre of the first magnetic sheet and the second magnetic sheet is symmetrical arranged described in described ventilation recess is positioned at.
As preferably, adjacent ventilation recess is interconnected formation ventilating duct, and connects ventilation shaft.
As preferably, described first magnetic sheet and the second magnetic sheet are the arc sheet coordinated with described body wall.
As preferably, the length that the arc sheet be disposed adjacent deflects because of spiral is no more than 1/3rd of arc leaf length.
The utility model has the advantage of:
Body described in melt high speed extrusion, electrostatic is there is through described conductive ring outside melt, the melt of static electrification is through magnetic field that the first magnetic sheet and the second magnetic sheet are formed and corresponding ventilation recess, melt is through ventilation recess, and be subject to the Lorentz force of self-magnetic field because of melt having electronic, Lorentz force makes melt not overflow ventilation recess and solidify, therefore often through a ventilation recess, melt just solidifies a length, until solidify whole girth to form spinning, until spray described body.Spinning is formed, and the phenomenon of dieswell no longer occurs.
