Description
Technical field
The present invention relates to and PTFE Nomex field more particularly to licker-in crochet hook hook up angular relative position automatic fine tuning control
Device processed.
Background technique
A kind of fiber that chemical property is extremely stable of PTFE Nomex dust-removal cloth-bag, its characteristics are as follows: 1. good permeabilities:
Permeability is the important indicator of measures filtration material property.The Air permenbility of polytetrafluoroethylene (PTFE) (PTFE) coated filter material can achieve
3-6m3/ ㎡ min, have been over the requirement of actual use.2. the wide adaptability of use environment: polytetrafluoroethylene (PTFE) (PTFE)
The performances such as the high-low temperature resistant of coated filter material, Anti-dew and chemical stability, not aging determine it to temperature, humidity and corrosivity
Gas have extremely strong adaptability, particularly to high concentration, high humility, subparticle dusty gas using effect more preferably, this
A little performances are all that current traditional filter material is incomparable.3. economic benefit is good: service life is closely related with economic benefit
(due to the special construction of PTFE polytetrafluoroethylpunched punched felt filter bag, making its service life up to 3 years or more) used in 3 years
Fund needed for conventional filter bag, is greatly more than the investment using PTFE polytetrafluoroethylpunched punched felt filter bag, and recycling is more valuable
The dust of value, so economic benefit is conceivable.100%PTFE Nomex filtrate be mainly used in chemical industry, waste incineration,
High-temperature resisting liquid filtering etc., keeps good chemical stability under the operating condition of various complexity.
Its production process includes: 1. fiber openings, and according to the requirement of technique, the fibrous raw material of various composition is claimed according to the proportion
Weight.It is first tentatively loosened, by big coma shredding, while the fiber of various composition in raw material being made to obtain uniform mixing,
Then smart shredding is carried out, fiber of further loosening, composite fibre ingredient, which wants shredding abundant, and it is uniformly mixed, and keep away as far as possible
Exempt from fibre damage；2. fiber combs, fiber, into air pressure cotton box, prepares feeding carding machine after shredding and being sufficiently mixed, into
Enter the combing that realization is acted on to fiber by winning between stripping roller and cylinder after carding machine, finally is transferred out to be formed by doffer
Web, the web by combing is frivolous single net at this time；3. lapping, fibre web enters lapping machine, and lapping carriage is by tooth form
The fiber list net of carding machine output is carried out cross folding, makes more with required breadth and unit grammes per square metre by V belt translation
Layer fibre web, for next procedure use；4. needle thorn compacting, fibre web enter needing machine, have in needing machine and largely have acicular hook
Puncture is repeated to web in pricker.Web is by laying repeatedly, and very fluffy when feeding needing machine, thickness can
It sees, but strength is poor, causes fiber upper and lower displacement when pricker punctures repeatedly in fibre web, generates extruding, draw close the fiber in fibre web
And it is compressed.Frictional force increases between fiber, and intensity increases, and forms the nonwovens with certain strength density；5. post-processing,
According to different process requirements, different post-processings is carried out to Nomex, processing mode has: (1) calendering.Pass through calender hot rolling
Non-woven material surface can be made smooth, smooth, thickness is uniform.The main purpose of calendering be increase non-woven material finish with
Planarization, and the tightness of material can be increased.(2) it singes.It singes and is mainly used in the non-woven material of dust or siccative filtering,
The filoplume of its protrusion of surface is burnt up, is allowed to bright and clean.(3) lotion impregnates.By manufactured Nomex be immersed in chemicals with
Lift pins pierce the properties such as high temperature resistant, acid and alkali-resistance, the antioxidant of lacing felt filter material.(4) high-temperature shaping.Nomex filtrate enters tentering baking
Case realizes the high-temperature shaping to filtrate.The deformation in use of the good filtrate of fixed effect is small, and filtrate dimensional stability is high, uses
Service life is long.(5) overlay film.Nomex filtrate obtained carries out overlay film with PTFE film by laminating machine, and filtrate coated with film will have
There is surface filtration effect, filtering accuracy improves, and can filter more tiny dust particles.Anticorrosion high temperature resistance is promoted.
For the above process, in fibre opening processes, fiber block cannot get sufficient shredding and just feed carding step, directly
The uniformity for influencing cotton net is connect, causes final finished felt face to form one one clouding, uniformity is poor, and thickness is different.
In addition, during fiber opening, it sometimes appear that blocking fiber or licker-in between licker-in and transmission device
On be wrapped over multifilament so that the shredding of fiber is not thorough, so that fiber is blocked discharge port and not blow not come out.
It is primarily present that fiber opening is uneven to above-mentioned two problems point, and fiber mixes the inconsistent problem of thickness degree,
Cause fiber fluffy degree insufficient, influences subsequent operating procedure.
In view of the above-mentioned problems, it is necessary to study a kind of licker-in crochet hooks to hook up angular relative position automatic fine tuning control device,
Improve the fiber fluffy degree in fibre opening processes.
