Abstract
The invention relates to a differential feed device, especially to a device for introducing a thin-fiber mat from a large reserve well channel so as to make introducing rollers running at different speeds. The device comprises at least one pair of introducing rollers rotating in opposite directions and at least one combing roller, wherein, the two opposed introducing rollers jointly perform operations on the fiber at different speed.
Description
Technical field
The present invention relates to a kind of differential feed equipment.
Background technology
Equipment being used for branch comb fibre bundle is fed into combing roller in order to make fibre bundle, and with the feed apparatus of roller groove combination and adopt the feeding of the no narrow point of the resilience roller of rotation in the opposite direction the same, paired feed rolls has also been used more than 100 year.A pair of feed rolls like this is normally identical, but on form, and these two also can have different surface textures as a pair of and cooperative roller.
Above-mentioned surface texture will help picking up of fiber, and controls fiber, with the combing roller by fast turn-around with fiber separation.On the other hand, make fiber can not enwind draw roll.
Also have drawing-in system, wherein, a pair of or two pair of rollers are introduced fiber one by one.The carding speed of pair roller that connects combing roller in the back is faster than the carding speed of formerly pair roller.
Always has approximately uniform circumferential speed as a pair of and cooperative roller.
In minute comb equipment, also there are two negative functions.Preferably make the feeding hoistway have bigger space, under normal service condition, to lay in relatively and equipment is controlled.On the other hand,, require between two draw rolls, to have one deck thin fiber felt, thereby realize that good pinching pinch and realize thus dividing comb for the hoistway of short shaft depth.The thick fiber felt can cause roller to damage, and it is middle that fiber effects is not clamped in not goodly, and agglomerating fiber can be dragged by combing roller easilier.For above-mentioned reasons, grew the feeding groove of the degree of depth and coarse combing roller before being normally placed in the more shallow groove of the degree of depth.This structure setting is very complicated.To this, French Laroche company just has such system very many years ago, wherein, the top that fiber groove that degree of depth is bigger and a pair of combing roller are arranged on a combing roller, they are arranged on again on the more shallow short groove of degree of depth as a unit.Pars fibrosa ground carries out the branch comb via bigger groove, directly drops on the narrower hoistway of the groove that is arranged in the below then, by the feed rolls of two adjacent alignment fiber is carried out the processing of essence branch comb again at this.
Said system is registered with document number US2009/0077770 by Temafa company.
Summary of the invention
The technical problem to be solved in the present invention is that a kind of groove and a kind of good opening box with big idle capacity is provided.
According to the present invention, in order to address the above problem, make two peripheral speeds that suck pair roller inequality, these two suction rollers act on the corpus fibrosum with certain speed corpus fibrosum are sucked, and corpus fibrosum is moved towards equidirectional, that is to say towards combing roller and move.Can consider, make a feed rolls slower than the speed that another feed rolls sucks material.Therefore, slower feed rolls not only suppresses fiber with respect to combing roller, also with respect to the fiber of feed rolls inhibition faster.
The surface texture of slower roller helps keeping fiber, and this is that these spikes have positive and negative relative angle or top owing to have spike on the surface of slower roller, reverse angle or top opposite with the direction of rotating.
Description of drawings
Fig. 1 shows the schematic diagram of one embodiment of the present of invention.
The specific embodiment
It for example is 600 very long shaft depth that fiber feeding groove 1 has, and wherein fills up fibre bundle 2.Feed rolls 3 and 4 is installed in the lower end of fiber feeding groove, and these two feed rolls are rotated with different speed, and introduces fibre bundle, fibre bundle is transported to combing roller 6.Divide the fiber of comb to be wrapped, have spike, the sensing direction of rotation that these spikes have, the opposite direction of the sensing direction of rotation that has again with the outside of the roller of low peripheral speed rotation.
Said system also can be used in the feeding of fibrofelt, and it is whole to be used for combing/comb.
Claims (4)
1. equipment that is used for branch comb fibre bundle, it has at least one pair of draw roll that rotates in the opposite direction and at least one combing roller, it is characterized in that, and two are oppositely arranged and the speed that acts on the fiber of the draw roll of cooperation with each other is different.
2. the equipment that is used for branch comb fibre bundle according to claim 1 is characterized in that on the direction of rotation of roller, the peripheral speed of second draw roll is greater than the peripheral speed of first draw roll.
3. the equipment that is used for branch comb fibre bundle according to claim 1 is characterized in that the diameter difference of described two rollers.
4. the equipment that is used for branch comb fibre bundle according to claim 1 is characterized in that, acts on the spike and the reciprocal spike of deflection in direction of rotation that the draw roll on the fiber has the deflection direction of rotation with low speed.
