Description
Technical field
The present invention relates to hollow-fibre membrane molding fields, and in particular to a kind of multistation wire feeder.
Background technique
Hollow-fibre membrane is a kind of important form of seperation film.In unit volume membrane module, hollow-fibre membrane it is effective
Membrane area is maximum, is separated by filtration high-efficient, and easy to clean, structure is simple, easy to operate, does not generate secondary dirt in production process
Dye, thus be widely used.Hollow-fibre membrane is one of the main form of film filtering, and film is in capillary, and micropore is located at tube wall
On, can solution be exactly that achieve the purpose that separation by these micropores with its component.
Hollow-fibre membrane is that hollow fibre filament is encapsulated in membrane tube, not only has high loading density, high ratio table
Area, and structure is simple, simplifies cleaning operation, leak detection repairing is convenient, rejection at a possibility that capable of effectively reducing germ contamination
The advantages that stabilization, long service life.
In the production process of hollow-fibre membrane, material silk still passes through charging tray, spinning head, coagulation tank, service sink and receives silk
Machine.
In hollow-fibre membrane during being encapsulated into membrane tube, need to pull hollow fibre filament to pass through spinneret by receive silk machine
Head superscribes membrane tube on the surface of hollow-fibre membrane using spinning head, but is guarantee doughnut when pulling hollow fibre filament
The specification of film is consistent, most productions that hollow-fibre membrane is carried out by the way of monofilm forming, inefficiency, and is carrying out multimembrane
When shaping simultaneously, it is different easily to occur doughnut thread tension in hollow fibre filament drawing process, and hollow-fibre membrane is caused to exist
The case where occurring different specifications in production process, being even broken, makes the batch production of hollow-fibre membrane be difficult to reach identical
Filter effect.
Summary of the invention
The technical problem to be solved by the present invention is to overcome present technological deficiency, providing one kind can be in multistation
Guarantee that the doughnut thread tension of each station is identical in empty fiber membrane forming process, hollow fibre filament is avoided to be broken and effective
Improve a kind of multistation wire feeder of production efficiency.
