Description
Technical field
The invention belongs to textile technology field, more particularly to one kind export the carded sliver to carding machine in carding machine clustering process
Impurity and short flannel remove and the device and method that is optimized of fibre orientation effect.
Background technology
Buncher is to draw web in bundles of device in carding machine.Web is turned by stripping for pattern doffing roller on doffer
Move, export into topping roll and bottom roll, form the web in straight tabular.Web fiber is formed after buncher closing in and is cut
Face is rectangular column flock.Web between top and bottom rolls and buncher close up is beloid triangle.Flock
Longitude circle bar device is collected in bar cylinder, is used for mixing in doubling step.
In the case of normal driving, top and bottom rolls are more than to the web between buncher closing in, left and right sides fiber speed
Median fiber movement velocity, therefore web drawing of fiber both sides is larger, middle is relatively low so that left and right sides thinner thickness,
It is middle slightly thick, web may be caused to break end；In buncher during boundling, the high-speed motion of web can form high pressure gas
Stream, aligns the flock peripheral fibres in entering when closing up and causes disturbance；Additionally, the web from roll output is received by buncher
The anxious gathering and the rubbing action of other auxiliary device of mouth, web can produce short flannel, dust, impurity, cotton wax etc., these materials
Not only cotton sliver quality is impacted, web broken end is also easily caused.In buncher, the broken end of web has a strong impact on carding machine reliability
Property, cotton sliver quality is reduced, is unfavorable for the lifting of automaticity, and increased the labor intensity of spinner.
This device is reequiped to traditional buncher.Semiclosed getter device, and and boundling are installed additional in buncher front end
Device forms a continuous fluid cavity body.On the one hand, the entrance of device can effectively exclude web from top and bottom rolls to boundling
Flyings during device in surface adsorption air；On the other hand, airflow function of the inspiratory component of attachment device to web, by cotton
The not contained impurity blowout for eliminating in net；Additionally, the drainage screen mesh area of air-breathing part is using pre-large post-small in this device
Structure design, can produce the adsorption of crescendo, moreover it is possible to which the orientation of fiber is further optimized to impurity in web.
The content of the invention
The technical problem to be solved is to provide one kind and promotes web remove impurity, optimization in carding machine clustering process
Fibre orientation the apparatus and method for reducing web broken end.Device increases web and moves between buncher closing in from top and bottom rolls
Buffering course, and in the process, increase remove impurity impurities removal and the orientation effect to web using the suction function of air-flow, so as to
Reduce carding machine production the carded sliver containing it is miscellaneous and contain short fiber content, improve cotton sliver quality.
In order to solve above-mentioned technical problem, the invention provides a kind of improve cotton sliver quality in carding machine clustering process
Device, it is characterised in that including doffer, pattern doffing roller, topping roll, bottom roll, buncher, upper pressure roller and lower compression roller, topping roll

The acute angle drift angle of network is 55 ° ~ 65 °, and acute angle drift angle correspondence catercorner length is 3mm ~ 5mm.
5. the device of cotton sliver quality is improved in carding machine clustering process as claimed in claim 1, it is characterised in that described
The mesh area filling rate D relevant parameter expression formulas of drainage screen are：
Wherein, a represents acute angle drift angle correspondence catercorner length,Grid wire width is represented,Represent 1/2nd acute angle drift angle angles
Degree, according to fibre length select a,、And D, the width of drainage screen grid wire, drainage screen are can determine with reference to the expression formula
During so that web being subject to negative pressure, holding power perpendicular to differently- oriented directivity can be provided for fiber, prevent web from rupturing.
6. the device of cotton sliver quality is improved in carding machine clustering process as claimed in claim 1, it is characterised in that described
Negative pressure cavity is divided into upper and lower two parts, respectively goes up negative pressure cavity（6）With lower negative pressure cavity（9）, upper negative pressure cavity（6）Upper end be provided with row
Miscellaneous mouth（7）, lower negative pressure cavity（9）Lower end be provided with lower impurity discharging port（8）.
7. it is a kind of in carding machine clustering process improve cotton sliver quality method, it is characterised in that using in claim 1-6 appoint
The device that cotton sliver quality is improved in carding machine clustering process described in one, including：Doffer（11）On web Jing stripping sieve
Draw（13）Transfer is stripped, via topping roll（14）, bottom roll（16）Output, in straight tabular, web is entered web at this moment
Web entrance（1）, the flyings in not firm enough the miscellaneous wadding of web surface attachment and air move to web entrance in web
Gradually it is excluded outside slot during slot；Move to gettering mouth（4）Web acted on by negative pressure, institute in web
The impurity for containing is sucked out, and by drainage screen（3）Discharge, while realizing the stretching to fiber, web continues steadily along web gettering
Chamber（2）After motion 20mm ~ 10mm, the closing in of web Jing bunchers（5）Boundling forms column flock, and flock is via horn mouth（10）
Guiding is transferred to pressure roller（19）And lower compression roller（20）Place, the upper pressure rollers of Jing（19）And lower compression roller（20）It is compacted into bar.
