Description
Technical field
The present invention relates to a kind of ring throstle drafting system.
Background technology
Two Apron Draft system is a kind of weighing draft that current ring spinning frame generally adopts.What this weighing draft was most crucial is two cushion rubber elastic nips, the structure of two cushion rubber elastic nip sells the upper cushion rubber of stretching on mainly overlapping on middle top roller and having, on middle bottom roller, cover has downside pin and the lower cushion rubber by apron tension frame stretching, at the middle part pre-set springs sheet of upper pin, spring leaf presses pin and upper cushion rubber downwards when drawing-off, it is made to be formed as a swingable elastic nip structure, the curvilinear characteristic of Here it is two cushion rubber elastic nip.Upper and lower cushion rubber combines and forms yarn flexibility gripping passage, 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 weighing draft improves front draft zone postmedian friction field intensity, compared with simple drawing-off, the Fiber Velocity point of yarn can be made in drafting process to move forward, it is more concentrated that the reach of Fiber Velocity point is conducive to Fiber Velocity point, can ensure that drafted yarn moves after drawing apart from deviation in a less interval, thus ensure the yarn quality not severe exacerbation because of stretch exercise.
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 friction between upper and lower cushion rubber, thus produce electrostatic, and cushion rubber is non-conductor up and down, and electrostatic is easily gathered on cushion rubber, fibre bundle by time it will be made to bring electrostatic.These electrostatic can bring many problems in drawing of fiber process: as being wound around rubber roll, cushion rubber, roller.Because electrostatic can repel mutually between fiber, fibre bundle is more also disperseed, and limit fiber more also leaves fibre bundle and becomes flyings (this is also one of reason that there are 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 movement velocity between the upper and lower layer fiber in yarn asynchronous, produces rubbing effect, affect the yarn indexs such as resultant yarn strand, filoplume, thickness joint to fibre bundle.
(3), speed difference between upper and lower cushion rubber, easily cause the instability of drafting force in drafting process, and stable drafting force is the key point ensureing normal drawing-off and yarn quality, larger draw force variation is difficult to the control overflow that grasping force in satisfied normal drafting process is greater than drafting force all the time, the guiding of fiber must be greater than control, can worsen yarn quality.
In addition, two Apron Draft system is larger by the impact of epidemic disaster.
Traditional two Apron Drafts be by upper and lower apron to through middle rear roller is micro-lead after yarn take to hold hold, mode that flat turn moves is transferred to front roller.Because upper and lower apron motion is by friction transmission, in two apron motion, lower apron is main transmission, the apron frictional force that so flexibility is good is larger, the situation occurring to skid just not easily occurs, and the apron that sclerosis qualitative change occurs just fairly produces the phenomenons such as skidding, displacement, pause and transition in rhythm or melody, the quality of impact spinning.So when workshop temperature is lower than 25 DEG C, emit rove, the indexs such as the phenomenon probability of happening such as harmful drafting are just high, and bar is dry will worsen; During lower than 20 DEG C, just produce and lead inextensible phenomenon, and cannot spin.
The impact of relative humidity on spinning is more obvious, relative humidity is lower than after 45%, because apron is non-conductor, easy generation electrostatic, under the effect of electrostatic, roller, apron can adsorb workshop flyings, floating dust, yarn after drawing-off is in twisting process, staple fibre also can expose formation filoplume, in this case, spins yarn evenness and filoplume will worsen.And in summer due to hot and humid, wrapping phenomena can be there is again, around roller, around roller, around apron etc., spun yarn board will end breakage rate increase, and production efficiency reduces.
In order to ensure spinning quality, textile enterprise will utilize air-conditioning system cool-down dehumidification summer, and winter production need be opened air-conditioning system and carry out humidification heat insulation work, and air-conditioning system power consumption is serious, considerably increases production cost.
