The creeling transmission mechanism of sliver lapper for carding machine
Technical field:
The present invention relates to sliver lapper for carding machine, relate in particular to the creeling transmission mechanism of sliver lapper for carding machine.
Background technology:
Carding machine is used for processing cotton fiber and chemical fibre, belong to textile machine, according to spinning technological process, comb and parallel cotton fibers prior to spinning is one important operation, the preceding working procedure of carding machine is Blowing-carding Unit, and later process is drawing frame (general comb technological process) or sliver lap machines (combing flow process).
The operation principle of carding machine is that cotton material that preceding working procedure is sent here carries out shredding and divides comb and removal of impurities, all cotton circle combings that are curling bulk are become to the filament substantially stretching, and remove broken seed, impurity and the short flannel carrying in cotton cleaning process, then the sliver of integrated certain specification is stored in cotton cylinder, for mixing in doubling step.The can coiler generally using in existing carding machine as shown in FIG. 1 to 3, comprise fuselage 1, dolly 2, cotton cylinder 3, transmission mechanism 4 and guiding mechanism 5, dolly 2 is arranged in fuselage 1, cotton cylinder 3 is arranged in dolly 2, transmission mechanism 4 is four-wheel Timing Belt haulage gears of air cylinder driven, comprise and drive cylinder 41, mobile belt wheel 42, linkage rack 43, belt 44, fixed pulley 45 and dolly drive contiguous block 46, drive the cylinder body of cylinder 41 to be fixed on fuselage 1 base plate, two mobile belt wheels 42 are arranged on linkage rack 43, linkage rack 43 is fixedly mounted on the piston rod that drives cylinder 41, belt 44 one end are fixedly mounted on fuselage 1 base plate, then walk around successively two mobile belt wheels 42 and two fixed pulley 45, the other end is also fixedly mounted on fuselage 1 base plate, dolly drives contiguous block 46 to be fixedly connected with belt 44, when driving the piston rod of cylinder 41 to stretch, synchronous drive is fixed on two mobile belt wheel 42 left and right traveling priorities on linkage rack 43, because the two ends of belt 44 are all fixedly mounted on fuselage 1 base plate, 44 of belts in mobile belt wheel 42 and fixed pulley 45 can drive dolly to drive contiguous block 46 to do straight reciprocating motion, thereby drive dolly 2 reciprocating.
In the creeling transmission mechanism 4 of this sliver lapper for carding machine, because the axis of mobile belt wheel 42 and fixed pulley 45 is all perpendicular to fuselage 1 base plate, in motion process, belt 44 is all the time in plumbness, belt 44 can be with transmission between mobile belt wheel 42 and fixed pulley 45, by regulating mobile belt wheel 42 to regulate the tensile force size of belt 44 between mobile belt wheel 42 and fixed pulley 45, after adjusting, through operation for a long time, belt 44 can be elongated, thereby causes belt 44 landing from belt wheel under the effect of deadweight.In addition, the suffered pulling force of belt 44 broad ways is not identical yet, easily causes belt 44 flange, thereby the wearing and tearing of aggravation belt 44 can cause belt 44 fractures when serious.Once belt 44 fractures are difficult for continued access, and these nylon steel core belt 44 costs are expensive, and also more rare on market, versatility is poor.
Summary of the invention:
The creeling transmission mechanism that the object of this invention is to provide a kind of sliver lapper for carding machine, it can make the creeling transmission mechanism operation of sliver lapper for carding machine more stable, longer service life.
The technical scheme that the present invention takes is:
A kind of creeling transmission mechanism of sliver lapper for carding machine, it is characterized in that: comprise driving cylinder, mobile sprocket wheel, linkage rack, chain, fixed chain wheels and dolly drive contiguous block, drive the cylinder body of cylinder to be fixed on the base plate of fuselage, linkage rack is fixedly mounted on the piston rod that drives cylinder, two mobile sprocket wheels are arranged on linkage rack, chain one end is fixedly mounted on the base plate of fuselage, then walk around successively two mobile sprocket wheels and two fixed chain wheels, the other end is also fixedly mounted on the base plate of fuselage, dolly drives contiguous block to be fixedly connected with chain, when driving the piston rod of cylinder to stretch, synchronous two the mobile chain crop rotation linear reciprocation that are fixed on linkage rack that drive move, chain in mobile sprocket wheel and fixed chain wheels can be done straight reciprocating motion between two fixed chain wheels, the dolly being hinged on chain drives contiguous block to drive dolly reciprocating.
Further, in two fixed chain wheels, there is a fixed chain wheels in chain linear reciprocation moving direction adjustable position, become the tightener sprocket of adjusting chain.
The creeling principle of dolly is as follows: because linkage rack is fixedly mounted on the piston rod that drives cylinder, two mobile sprocket wheels are installed on linkage rack, drive the flexible of piston rod of cylinder will drive two mobile sprocket wheels along rail moving, being wrapped in two chains on mobile sprocket wheel will do reciprocating linear motion between two fixed chain wheels.
Because dolly drives contiguous block to be hinged on chain by dolly, so dolly moves with chain row culture linear reciprocation, thereby meets the linear reciprocating motion requirement of creeling.Creeling dolly adopts after chain sprocket drive mechanism, and chain is difficult for coming off from sprocket wheel, if chain has micro-elongation after long-play, as long as regulate a fixed chain wheels wherein, make chain tension, this drive mechanism is reliable and stable, and the probability of chain breakage is minimum.Meanwhile, chain is standardized part, cheap, and versatility is good, even if chain surprisingly ruptures, also can change easily corresponding brace and carry out quick and economic maintenance.
