Description
Technical field
The utility model relates to the weaving production technical field.
Background technology
Textile mills' raw cotton is processed in lap or the cotton layer through the opening picking combination machine, and the fiber majority is loose cotton piece or flock state, and contains 40%～50% impurity, and wherein majority is less band fiber or stronger impurity and the cotton knot of adhesion.For satisfying the requirement of later process, this textile mills' critical process of carding machine is being undertaken the task of lap being processed the carded sliver.In the spinning process; On the basis that fiber is fully separated; Continue to remove the impurity and the fault that remain in the cotton layer; And mostly impurity and fault will be got rid of in the car tripe of back, and the fault impurity of eliminating is sneaked into sliver if can not in time clear up to machine will have a strong impact on product quality, and the while also increases the labour intensity that the spinner sweeps.
Both at home and abroad the car tripe district that falls to mix all is divided into three zones behind all carding machines, that is: first district, second that falls to mixing falls to mixing and distinguishes and the 3rd district that falls to mixing.First falls to mixing in the district, and the air-flow that the carding machine licker-in drives increases gradually, and thickness is also along with thickening.Requirement mends air-flow down from feed plate; Mend air-flow the fiber on the licker-in is played certain holding effect; And the boundary-layer that thickens to carding machine mote knife place; Because of spacing of mote knife and licker-in less, most of air-flow is stopped by mote knife and flows downward along the knife back that partial impurities and staple fibre fall thereupon.Therefore, first district that falls to mixing can get rid of more big assortedly, and its assorted content accounts for back car tripe and falls assorted below 70%.Then, another part air communication is crossed and is got into second district that falls to mix behind the mote knife, and boundary-layer begins again to thicken, and mote knife is cut apart boundary-layer, and the part air-flow does not have the knife back to flow downward, and impurity and staple fibre be whereabouts thereupon also.Therefore, mainly to eliminate fraction greatly assorted and most of than small impurities for second denuded zone.Begin again to thicken after the air communication that another part entering licker-in and mote knife space is crossed the combing plate cotton guiding plate, and require to mend air-flow down, equally the fiber on the licker-in is played certain holding effect from cotton guiding plate.By mote knife cutting at the bottom of the little leakage, the part air-flow folds into the car tripe to the boundary-layer that thickens again, and the trifle in the world in the air-flow also falls into the car tripe thereupon.Therefore, the 3rd denuded zone mainly is to utilize air pressure to get rid of short flannel and dirt bits.
Behind the modern carding machine car tripe the cotton mode of suction mainly contain two kinds of forms.First kind of mode is to concentrate to inhale, that is: back car tripe all fall to mix to all falling within the car tripe board of back, concentrate the suction simultaneously that will fall to mix in a large number to arrange to dust chamber behind the house steward on the machine by back car tripe air draught bucket arm then; Second kind is disperse to inhale, that is: each denuded zone has one to inhale point, inhales points for totally three, is discharged into dust chamber after house steward is connected with will going up respectively through bellows then.First kind of suction falls to mixing mode because the bigger air quantity of the big needs of total amount that falls to mix, negative pressure could fall to mixing to distinguishing to fall to mixing with a large amount of three siphons away fully; Need very big fan energy consumption; Do not have enough air quantity, negative pressure, back car tripe falls to mixing not that easy-clear can increase the frequency and the labour intensity that the spinner does cleaning.Mode is reasonable than the former though second kind of suction falls to mixing, not based on the fall size of assorted composition and quantity distribution air quantity, negative pressure of three districts that fall to mix.Under this mode, air quantity, negative pressure immobilize, can not be according to raw material impure and short flannel situation correctly adjust air quantity, negative pressure.The same suction point of the carding machine both sides of great majority dispersion suction mode have inhales assorted phenomenon simultaneously; Make that like this inhaling the some place middle negative pressure of airduct is zero; Cause interstitial impurity to be difficult for getting rid of; Fall to mixing to being taken away and sneak into the quality that web directly influences sliver, also can not increase the burden that cover plate and cylinder divide comb removal of impurities work even do not influence web quality by the carding machine licker-in.There is not the unfavorable factor of waste air quantity, negative pressure in the both sides air draught of same suction point, causes bigger blower fan energy waste.
Being inhaled the analysis of the adverse effect factor that falls to mixing can know by car tripe behind the above-mentioned carding machine, and mainly there are five big conspicuous defectives in car tripe suction noil behind the modern carding machine: (1) is concentrated and inhaled bigger suction air volume and the negative pressure of needs, is unfavorable for energy savings; (2) concentrate suction back car tripe to fall to mixing greatly, can increase spinner's labour intensity with air quantity, negative pressure fluctuation; (3) disperse to inhale and to fall to mixing to distinguishing air quantity, negative pressure according to the actual conditions reasonable distribution that falls to mixing; (4) great majority disperse to inhale some both sides and are drawn assorted simultaneously, make that negative pressure is zero in the middle of the suction pipe, influence impurity-eliminating effect and waste energy; (5) disperseing to inhale great majority suction point all is closed not quick detachable cleaning.
Summary of the invention
The utility model purpose is to propose a kind of convenient control, energy-conservation, the air draught control device of car tripe behind the carding machine efficiently.
