Description
Technical field
The invention belongs to the Weaving device field, especially the feeder of carding machine of spinning unit.
Background technology
Opening picking has dual mode with being connected of carding step in the cotton system: the one, and traditional scutching cotton rolling feeding carding machine.The 2nd, comb connection technology clearly, feed carding machine by clear comb connection hopper in the sheet cotton mode, claim clear comb connection carding machine.Tradition carding machine spun speed, productive rate are increasing, and short fiber content also increases thereupon fast, this means that more effective length fiber sustains damage.For this reason, multiple measure is worked out in the repetition test research of many spinning factory, with the damage of minimizing effective length fiber, and obtains certain effect, but still has further improved potentiality, particularly clear comb connection carding machine, and short fiber content increases very fast.
Switzerland's Rieter (RIETER) company is improved to forward feeding to the feeding mode of fiber on the carding machine, now domestic and international most types all adopt this mode, but this measure only relates to the feeding direction, does not consider the improvement to feeding lap or sheet cotton internal fiber structure, so fail to bring into play bigger effect.
Known volume is fed feeder of carding machine, comprises frame, driving mechanism, gives cotton roller, feed plate and lap roller; Be installed on the feed plate to cotton roller, feed plate is installed on the frame, and lap roller also is installed on the frame, and drive mechanism is given cotton roller, again by driving lap roller to cotton roller.Type of drive is: the bevel gear on the side shaft meshes with giving the bevel gear on the cotton roller axle, and the side shaft rotation rotates for cotton roller thereupon, makes the incorgruous revolution of lap roller by two gap bridge spur gear transmission for the spur gear on the cotton roller axle.The feeding lap places on the lap roller, send before the pincers mouth that its cotton layer warp of sending forms for cotton roller and feed plate, accepts branch comb, the shredding of licker-in.
Known hopper feeding carding machine device, the clear connection hopper of combing feeds carding machine in the sheet cotton mode, comprises frame, driving mechanism, joins hopper and sheet cotton delivery roller to cotton roller, feed plate, clear comb.Feed plate places on the cotton roller, places on the frame to cotton roller, is equipped with on the feed plate to detect the thin displacement sensor that changes of cotton bed thickness, sensor link signal amplifier.Show direction feeding feed plate and the pincers mouth of forming to cotton roller from the cotton layer of sheet cotton of clear comb connection hopper output along vowing, the thin variation of cotton bed thickness, reach computer control system by sensor by amplifier, control system is after relatively calculating, servo drive system, servomotor are sent instruction, make to after the cotton roller speed change, accept the combing of licker-in again, reach the carded sliver is carried out the neat and well spaced purpose of short-movie section.
On existing carding machine, when fiber is carried out combing, all there is the situation of damage, comb protruding end, when particularly under high speed high yield situation, using, association and what come is increase to effective fibre damage with it causes the surge of carded sliver short fiber content, has become a historical technology difficult problem together.
