[summary] cone winder regards spinning process as medium important equipment, technical innovation is rapid in recent years. Abroad is full automatic machine of gauze of subsidiary channels in the human body through which vital energy already developed the 3rd generation in 20 centuries end, have accurate winding, nicety to spin fold, check of bolt of splice of clear gauze of accurate fixed length, electron, air, online quality and gauze defect classification, energy-saving fall the characteristic such as bad news. The article is based on a stage to amount to VFD-F transducer, discuss its to be in fan of negative pressure of automatic winding machine is energy-saving the application on control. [keyword] energy-saving constant negative pressure controls transducer of automatic winding machine one, foreword is automatic cone winder is the crucial equipment that industry of implementation spin industry upgrades, home market has about 2600 right-and-left demand every year, go up century at the beginning of 90 time, chinese automatic winding machine counts an import for the most part, main entrance type is mixed for the 2nd generation the 3rd acting automatic winding machine. Go up century since 90 years of metaphase, qingdao is baronial company and Shanghai 2 spin machine introduce technology of the 2nd acting automatic winding machine to form crop from Italy and Germany respectively, introducing digest absorb a foundation to go up, in recent years, two companies part at own research and development the 3rd acting automatic winding machine, form batch. The amount of all sorts of winding machine that at present enterprise of spin of our country cotton is using has 30 thousand about. Graph 1 cone winder the position in spinning technological process 2, winding machine is basic canister of working procedure sth resembling a net (call subsidiary channels in the human body through which vital energy gauze again) the first working procedure that is the preparation before knitting, its task is to will come from the cop that spins a ministry or skein to machine the tube that accords with particular demand on cone winder. Working procedure of canister of subsidiary channels in the human body through which vital energy can generalize for the following at 2 o'clock: A.

Because steel gets diametical limitation, make the amount allowing gauze on canal of spun yarn gauze very limited, cannot use at weaving directly, adopt working procedure of canister of subsidiary channels in the human body through which vital energy will raw yarn (or filament) the tube of decoy of make it high capacity, offer warping, roll of abb, knitting, shuttleless loom offer abb or float catch wait for working procedure. General in special its circle the tube of gauze length can amount to 100 thousand meters or so. B.

The certain defect on cleared yarn, acrobatics, improvement yarn character. The raw yarn that comes by the carry that spin a factory has more exterior flaw commonly, when the clear gauze device that goes up through cone winder, can keep clear of the nap on its, dirt bits reachs the foreign matter defect such as weak gauze, wide ties, such, already the exterior quality of ameliorable fabric, increased their average strength besides gauze on-line weak point because of get rid of again, reduced yarn hind the broken end in line working procedure. Graph the automatic winding machine of 2 models is current the market the 3rd acting automatic winding machine, on gauze, clear gauze, retreat twist, the splice that break gauze, winding figuration all realizes automata to finish, divide in addition, advanced sex still reflects its skill in: A.

Canister gauze tension is even, density is even and can accuse; B.

Get used to; C of special package requirement.

Of precision of canister gauze length can accuse; D.

Get used to the; E of gauze of subsidiary channels in the human body through which vital energy of all sorts of different yarn.

Working procedure of canister of subsidiary channels in the human body through which vital energy realizes; F of feebleminded bad news.

Craft of canister of subsidiary channels in the human body through which vital energy realizes low cotton waste to use up.

Among them the low specific power consumption of working procedure of canister of subsidiary channels in the human body through which vital energy, basically control technical implementation through negative pressure of constant of fan frequency conversion. 3, specific power consumption of automatic winding machine analyses automatic winding machine to already realized odd ingot control in the round at present, small-power dc is used to not have in great quantities in drive of odd ingot motivation brush electric machinery and pace to enter electric machinery, convenient implementation odd ingot is opened stop control. In the meantime, of odd ingot open stop, the action that affects canister gauze to suck gauze arm a place with a draught directly, affect size of air negative pressure and dosage at the same time. The 2nd generation, the 3rd acting inchoate and automatic winding machine, negative pressure fan by labour frequency direct drive, power of fan electric machinery presses the greatest negative pressure and air consumption design, namely no matter canister of odd ingot sth resembling a net is started, full load of fan electric machinery runs, power comsumption waste is big. The 3rd acting later period is automatic fan of cone winder negative pressure is controlled by transducer, negative pressure sensor detects in real time negative pressure of negative pressure air channel, its can according to air consumption size rotate speed of self-adjusting electric machinery suction wind.

If do not have or only less ingot movement, suck low speed of wind electric machinery to move, can reduce fan power comsumption at this moment 50% above. If be in,some shorter period of time has a lot of ingot-shaped tablet at the same time movement, sensor of its negative pressure can be collected in time negative pressure is worth at that time, convey directly transducer control plate, pass transducer automatic operation, change electric machinery rotate speed quickly, maintain in order to make sure negative pressure is accurate go up in set value, make sure thrum is caught rapid and effective, achieve goal of pilot of energy-saving constant negative pressure. Power comsumption of place of fan of the negative pressure in pressing cone winder is compared, case supports this design to be able to make overall and average power comsumption can be reduced at most 27% .

5 times square curve notes: Take ★ to be indispensible modification parameter, the others is optimize parameter. C.

The note is current the 3rd acting cone winder, advocate accuse to go up to adopt labour to accuse machine and sheet more piece machine form, ability of its system interference rejection is worth not strong; Use frequency conversion is controlled, layout and debug an attention to prevent interference design; Of transducer parameter optimize a design, energy-saving to fan effect has immediate effect. 5, 4 old automatic winding machine of the world before market of cone winder frequency conversion analyses eye produce business: Germany is granted come to company of blessing company, Japanese village field, Italy Sa Weiao company, China great company holds Qingdao domestic majority is automatic cone winder market. Among them Sa Weiao company and young great company part in Shandong aid Ning Heqing island built large-scale production base. As a result of inchoate our country automatic winding machine counts an import, main entrance type is mixed for the 2nd generation the 3rd acting automatic winding machine, its did not equip for the most part system of frequency conversion fan, its frequency conversion is energy-saving transform the market to be worth to pay close attention to.
