HFJ Compact Spinning Device

H-fang / Chinamakes full use of technological achievements which have been made in the fieldof textile machinery in the combination of new type spinning technology fromlocal and abroad, developed a series of products such as compact spinning systemfor ring spinning machine, air-jet spinning machine, intelligent doffingtrolley, Axminster carpet loom and the new type of ball warper and rebeamer. Allthese efforts make contributions to promoting the textile the progress ofindustry development.

Huafang new technology research Co. Ltd uphold therefine on, the relentless pursuit of excellence of confidence and courage, andconstantly enrich the experience and achievements which a professionalmachinery manufacturers should have. 

With strictmanagement and the production experiences accumulated in years, H-fang / Chinais committed to provide from modeling, process, to all kinds of high qualityand high performance of mechanical equipment texture inside and outside.

H-fang / Chinacherishes every opportunity to establish and maintain a firm and lastingbusiness cooperation with all customers for mutual reciprocity and mutualbenefit, common development hand in hand!

StructureCharacteristics 

• Four-roller system, apron lattics are of positive drive.

• Negative pressure system adopt main blower with general air duct and filternet to avoid dirtying workshop.

• Modular design,6 spindles or 8 spindles in one unit.

• Well-designed negative pressure distribution ensures consistency of airflowat each suction nozzle.

• The suction nozzle of suction pipe is of optimization design for integratingthe strand of fiber easily.

• Inverter is available for controlling the negative pressure of compactspinning for different yarn count.

• Smoothly moving of the yarn is guaranteed by tension device of the apronlattice (patent product of H-FANG).

• Close-loop control for negative pressure system ensures stable pressure duringspinning. (For option)

• Autocotton - stripping device for high automation of the equipment. (For option)

Environmentrequirements

Requirements which to ensurebetter yarn result from compact spinning

1.       Ring frame equipped withtraveling cleaner

2.       Temperature, humidity and dustcontent of the air in the workshop:

a.       Temperature: 25 - 30ºC constant for all year

b.       Relativehumidity: 55±5% for cotton, 75±5% for wool and silk

c.       Dust content of the air: < 3mg/m3

When modifying old ring frame,no need to drill on the beam frame, no need to change anything on the drivingparts or parts beneath the beam frame. Thus will not destroy any part of themachine. For the drafting section, only change roller stand, front bottomroller, flute pipe unit and add compact device. Then change fan case and changeroving creel. In case of top duct solution, even no need to change roving creel

•Big fan, double ducts, small pressure difference convenient for conversion

•Overhead duct and transparent branch pipes, no block-off sight from both sides,no change in rovings position

•Pressure auto-detecting/alarming system avoid yarn breakage due to lowpressure 

•Auto strip device ensure constant pressure during machine running

•On-line monitoring convenient for central monitoring the whole spinning process(for option)

•Can be applied with ring frame suppliers for new machine.

HFJcompact spinning assembly also can be applied for worsted and semi worstedspinning to improve the yarn quality to get high benefit. It’s a perfectsolution for producing high quality single yarn fabric because when usingcompact device, less work is left for burling, which can increase the weavingefficiency.

SS. strips for profiled tube slotsmade of high wearable materials, to meet different demands as well as solutionfor worn out old profiled tubes

• Multiple specifications fordifferent processes and yarn type option

• Smooth and wearable surface,reduce environmental pollution cause during wearing out of old profiled tubesurface

• Easy installation and change,formed die and high exchangeable
