The fiber net collecting and compressing device comprises a collecting and compressing device arranged on a fixed plate, and is structurally characterized in that a collecting passage is arranged at the upper part inside the collecting and compressing device, the lower end inside the collecting and compressing device is made into a compressing passage, the diameter of the collecting passage is greater than the diameter of the compressing passage, the collecting passage and the compressing passage realize the transition through inclined surfaces, and inclined holes are arranged in positions on the collecting and compressing device corresponding to the compressing passage.
Description
Technical field
The utility model relates to field of textile machinery, in particular, relates to the improvement that fiber web draws the compression set structure in.
Background technology
In the spinning manufacture field, some operation relates to draws and is compressed into fiber web in ribbon closely.As: in the cotton spinning mixing in doubling step,, when the output drawing frame, fiber web be drawn in by the fiber web of drawing frame one roller output, and compression form sliver closely.
As shown in Figure 4, in this course, fiber web 20 draws in by 50 pairs of fiber webs 20 of buncher earlier.By fixing horn mouth 40, the fiber web 20 after drawing in is compressed again.Afterwards through pressing roller 10, with the ribbon output of compression.
Existing apparatus draws in fiber web 20, and is compressed into the process of tight fibers bar, is all finished respectively by buncher 50 and horn mouth 40.
To produce supermatic demand in order adapting to, the loose fiber net 20 of buncher 50 inside need to be penetrated in the compressing hole of horn mouth 40 automatically.Therefore, form hermetically-sealed construction between the buncher 50 of existing gathering compression set and the horn mouth 40.On horn mouth 40, have the inclined hole that is used for forming negative pressure at horn mouth 40.In the time the loose fiber net 20 of buncher 50 inside need being penetrated horn mouth 40, in the inclined hole of horn mouth 40, feed compressed air, compressed air flows out from the compressing hole of horn mouth 40 lower ends; At this moment form negative pressure on the top of horn mouth 40 and the inside of buncher 50, loose fibres net 20 is penetrated in the horn mouth 40.After finishing fiber web 20 and penetrating work, cut off compressed air.
The conditional request that forms sealing between the buncher 50 of this structure and the horn mouth 40 is very strict, and the negative pressure that buncher 50 inside often occur weakens phenomenon.This can cause can't finish the situation generation that loose fiber net 20 penetrates horn mouth 40, influences fiber web 20 and penetrates finishing of horn mouth 40 functions automatically.
In addition, the gathering compression set that uses is between buncher 50 and horn mouth 40 now, there is the part of not enriched by fiber web 20, and the air that comprises in the loose fiber net 20 of the part of not enriched by fiber web 20 is in its compressed process, and the air in the fiber web 20 is squeezed out fiber web 20.Between the buncher 50 and horn mouth 40 that are not enriched, form unsettled eddy current by fiber web 20.When fiber web 20 high-speed motions, the fiber fines bundle of the fiber web 20 that dissociates can be under unsettled eddy current drives, and easily forms crotch, fault such as folded in the ribbon after compression.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of simple in structure, can reduce crotch, fault such as folded, is convenient to the fiber web that fiber web passes and draws compression set in.
For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme: the utility model comprises the gathering compression set that is arranged on the fixed head, the described gathering compression set of its structural feature inner and upper is set to draw in passage, draw the compression set interior lower end in and be set to pressure channel, the diameter of described gathering passage is greater than the diameter of pressure channel; Draw passage and pressure channel in by chamfered transition, draw on the compression set and be provided with inclined hole corresponding to the pressure channel place.
The beneficial effects of the utility model: 1, simple in structure: the utility model adopt to draw the function that compression set has been realized buncher and two devices of horn mouth in the existing equipment in.Simplified the structure of equipment greatly.
2, can reduce crotch, fault such as folded: draw passage and pressure channel in owing to be provided with in the gathering compression set of the present utility model, and pass through chamfered transition; Therefore, fiber web is in drawing passage and pressure channel in the time, the space of drawing in the compression set all can be enriched, air in the loose fiber net is in compression process, in fiber web, be extruded, in drawing passage and pressure channel in, form stable air pressure, can not form unsettled eddy current.Like this, just reduced the fiber fines bundle fibroreticulate chance of dissociating.Also just reduce the crotch that in fiber web, forms, fault such as folded, improved the quality of product.
3, being convenient to fiber web passes: because gathering passage of the present utility model and pressure channel are as a whole, so do not exist sealing bad, the phenomenon that causes its internal negative pressure to weaken, therefore, can be practical finish passed the action of drawing compression set in fiber web, adapts to supermatic production better.
Description of drawings
Structural representation when Fig. 1 is work of the present utility model.
Fig. 2 is the utility model taking-up of drawing compression set in, lays view.
Fig. 3 is the structural representation that draws compression set in.
Structural representation when Fig. 4 is the work of existing gathering compression set.
In the accompanying drawing 1 for pressure channel, 2 for fixed head, 3 for floating bushing, 4 for draw in compression set, 5 for draw in passage, 6 for draw in cover, 7 for rotating shaft, 8 for inclined hole, 10 for press roller, 20 for fiber web, 30 be a roller, 40 for horn mouth, 50 be buncher.
The specific embodiment
The utility model comprises: be arranged on the gathering compression set 4 on the fixed head 2, described gathering compression set 4 inner and upper are set to draw in passage 5, draw compression set 4 interior lower end in and be set to pressure channel 1, the diameter of described gathering passage 5 is greater than the diameter of pressure channel 1; Draw passage 5 and pressure channel 1 in by chamfered transition, draw on the compression set 4 and be provided with inclined hole 8 corresponding to pressure channel 1.
Link to each other described gathering compression set 4 dismountable being arranged in the floating bushing 3 by rotating shaft 7 with floating bushing 3 on the described fixed head 2; Being convenient to the workman will draw compression set 4 in and take out or lay.
The upper end of described gathering compression set 4 is provided with draws cover 6 in, can better collect the fiber web 20 that is transported by a roller 30 by drawing cover 6 in.
As a whole when drawing compression set 4 in 6 uses of gathering cover, for easily manufactured, draw compression set 4 in and can be processed into independent part respectively with gathering cover 6, be assembled into one again at last.
Below in conjunction with description of drawings one action process of the present utility model: the fiber web 20 by 30 outputs of drawing frame one roller enters the gathering passage 5 that draws compression set 4 tops in by drawing cover 6 in, and fiber web 20 is drawn in the loose fibres bar.The loose fibres bar is drawn in pressure channel 1 compression of compression set 4 again.When fiber web 20 is drawn out gathering compression set 4, form the tight fibers bar of compression.By pressing roller 10, ribbon is exported closely again.
Whole device, simple in structure, good reliability.With a device, the work of finishing respectively by buncher 50 and 40 two devices of horn mouth before finishing.Simultaneously, make the flow direction of fiber web 20 when forming the conpressed fibers bar more become reasonable.And can effectively reduce from fiber web 20 draw in, to the process that is compressed into the tight fibers bar, the generation of crotch, fault such as folded improves yarn quality.
