Background technology

Former spinning and spin the equipment of hair: fibril aggregation is bad, is in loose condition (of surface), the fiber at many yarns edge lose or with certain form be attached on the yarn or twisted in yarn, and form how assorted Yarn filoplume is, the bar bar uniformity is poor.Beaming device mainly is negative pressure cluster type main frame tool cluster type two series products both at home and abroad now, and the principle of boundling is to reduce to spin the preceding yarn trigonum of twisting.

Negative pressure net circle formula device: the representative of this form is the product of German Suessen and Japanese Toyota.This device is to add shape tube before former spinning head roller, have the skewed slot about two mm wides on the shape tube, be with the nylon wire circle on the skewed slot, the yarn that former drawing-off is good during work rotates output by yarn nylon wire circle, nylon wire circle frictional rotation on shape tube, negative-pressure air-flow by the skewed slot on the shape tube to the yarn boundling.Because the nylon wire circle is not wear-resistant, every ingot frictional rotation speed can be different, and the CVB that causes sliver to do descends, and this shortcoming is fatal to yarn quality.This device has the following disadvantages: 1, the nylon wire circle cycle in service life is short, need the frequent nylon wire circle of changing, cause yarn spare quality instability, the nylon wire circle removes cleaning weekly, homemade nylon wire circle 15 days is changed, and import nylon wire circle was changed in two months, and cleaning, to change labour intensity big, waste time and energy, reduced operating efficiency; 2, since on the net circle formula device shape tube skewed slot be full opened state, in the time of playing the effect to the enough boundlings of yarn, negative-pressure air-flow will reach more than two kPas on the nylon wire circle, power consumption is big; 3, skewed slot is that two millimeter width are width of boundling trigonum, and the width that makes yarn rolling further reduce the boundling trigonum by the air-flow on the skewed slot just can reach the boundling effect to yarn, and this causes the not smooth resultant yarn evenness quality that influences of yarn channel to worsen; 4, shape tube is because the frictional rotation of nylon wire circle can be worn and torn and be changed in 3 years, and maintenance cost is significantly increasing always.

Negative pressure dust cage formula: being the device product that Switzerland Lite Machine Ltd exclusively makes in the world, is the tight spinning equipment product of present most advanced world.The principle of this equipment beaming device is the same with negative pressure net circle formula device: just the nylon wire circle is accomplished on the hollow roller lasso (being mesh-like) that negative pressure is by the getter device boundling yarn trigonum in the roller lasso.It is the skewed slot that has two millimeter at inspiration piece.The advantage of this equipment beaming device is the defective that has overcome the wearing and tearing of nylon wire circle, be state-of-the-art in the world, but owing to be semi-open state on the skewed slot on the inspiration piece in the roller lasso, two millimeter have wide 20 a millimeters baffle plate to control air-flow (width of mesh-like) on the roller lasso, when playing the effect to the enough boundlings of yarn, negative-pressure air-flow on the mesh-like will reach more than 1,200 handkerchiefs, and power consumption is big; Skewed slot is that two millimeter width are width of boundling trigonum, and the width that makes yarn rolling further reduce the boundling trigonum by the air-flow on the skewed slot just can reach the boundling effect to yarn, and this causes the not smooth resultant yarn evenness quality that influences of yarn channel to worsen; 59 millimeters of roller cover loop diameters, it is many that material is used; The netted hole of roller lasso top sieve is more than 700, and manufacture difficulty height, cost are too big; Working environment requires very high, and the temperature and the relative humidity that have higher requirements are controlled flyings, and air-conditioning requirement turnover air-flow all has filtration system, and the environment fund input is very big; The spinning suiting kind is single, only limits to combed cotton more than 60, and is not enough because spinning the required negative pressure of other raw material; Maintenance workload is big, and every first quarter moon requires must shut down clears up getter device that roller screen cloth and cleaning split out once; And fetch long price, more than 3,000 yuan on the present every ingot of the price of this boundling equipment.

(2) mechanical compaction formula: the representative of this form is the product of Switzerland's Rochas, also has the patent of my application, and the patent No. is 200420091918.3, and it is many that these two kinds of devices all do not have thoroughly to solve spun Yarn filoplume, and fibre strength is low, the problem that flyings are many.
