Description
Technical field
The present invention relates to a kind of ring throstle drafting system.
Background technology
Two Apron Draft systems are a kind of drawing-off forms that current ring spinning frame generally adopts.What this drawing-off form was most crucial is two cushion rubber elastic nips, the structure of two cushion rubber elastic nips is mainly the upper cushion rubber that cover is sold stretching on having on middle top roller, on middle bottom roller, cover has downside pin and the lower cushion rubber by apron tension frame stretching, at the default spring leaf in the middle part of upper pin, spring leaf presses pin and upper cushion rubber downwards in the time of drawing-off, make it be formed as a swingable elastic nip structure, the curvilinear characteristic of Here it is two cushion rubber elastic nips.Upper and lower cushion rubber is in conjunction with forming the flexible passage that grips of yarn, and in order to strengthen gripping channeling, this channels designs becomes by the determined tracing pattern of upper and lower pin form.Two cushion rubber elastic nip drawing-off forms have been improved front draft zone postmedian friction field intensity, compared with simple drawing-off, in drafting process, can make the Fiber Velocity point reach of yarn, it is more concentrated that the reach of Fiber Velocity point is conducive to Fiber Velocity point, can guarantee that drafted yarn moves apart from deviation in a less interval after drawing-off, thereby guarantee that yarn quality is not because of stretch exercise severe exacerbation.
But the linear velocity of upper and lower cushion rubber exists certain difference all the time, this speed difference can bring the harmful effect of the following aspects in drafting process:
(1), the speed difference that exists between upper and lower cushion rubber can make to produce between upper and lower cushion rubber friction, thereby produce static, and upper and lower cushion rubber is non-conductor, static is easily gathered on cushion rubber, fibre bundle by time will make it bring static.These static can bring many problems in drawing of fiber process: as being wound around rubber roll, cushion rubber, roller.Between fiber, because static can repel mutually, fibre bundle is more also disperseed, limit fiber more also leaves fibre bundle and becomes flyings (this is also to have one of reason of a large amount of flyings in Cotton Textile Enterprises air), increases harmful filoplume and breakage etc.
(2) speed difference, between upper and lower cushion rubber, easily causes between the upper and lower layer fiber in yarn movement velocity asynchronous, and fibre bundle is produced to rubbing effect, affects into the yarn indexs such as Yarn Evenness, filoplume, thickness joint.
(3), speed difference between upper and lower cushion rubber, easily cause the unstable of drafting force in drafting process, and stable drafting force is the key point that guarantees normal drawing-off and yarn quality, larger draw force variation is difficult to meet the control requirement that guiding that grasping force in normal drafting process is greater than drafting force, fiber all the time must be greater than control, can worsen yarn quality.
In addition, two Apron Draft systems are subject to the impact of temperature, humidity larger.
Traditional two Apron Drafts are to be transferred to front roller by the mode that upper and lower apron is held taking to hold through the yarn that middle rear roller is micro-after leading, flat turn moves.Because upper and lower apron motion is by the transmission that rubs, in two apron motions, lower apron is main transmission, the apron frictional force that flexibility is good is so larger, the situation of skidding is just difficult for occurring, and the phenomenons such as the apron that sclerosis qualitative change occurs skids with regard to very easily producing, displacement, pause and transition in rhythm or melody, the quality of impact spinning.So workshop temperature during lower than 25 ℃, is emitted rove, go out the phenomenon probability of happening such as hardhead just high, bar is dry etc., and index will worsen; During lower than 20 ℃, just produce and lead inextensible phenomenon, and cannot spin.
Relative humidity is more obvious on the impact of spinning, relative humidity is lower than after 45%, because apron is non-conductor, easily produce static, under the effect of static, roller, apron can adsorb workshop flyings, floating dust, yarn after drawing-off is in twisting process, staple fibre also can expose formation filoplume, and in this case, spinning yarn evenness and filoplume will worsen.And in summer due to hot and humid, can there is again wrapping phenomena, around roller, around roller, around apron etc., spun yarn board will end breakage rate increases, production efficiency reduces.
In order to ensure spinning quality, textile enterprise will utilize air-conditioning system cool-down dehumidification summer, produce winter and need unlatching air-conditioning system to carry out humidification heat insulation work, and air-conditioning system power consumption is serious, has greatly increased production cost.
