Description
(1) technical field
The present invention is a kind of nipper modular construction of textile industry combing machine, particularly relates to the power transmission arrangment of combing machine nipper.
(2) background technology
Known; In order to improve the quality of chemical fibre cotton woolen knitwear; Important operation combing sliver in Textile Engineering, its effect are to remove wherein staple fibre, impurity, cotton knot and fault etc. through combing by the carded sliver web of carding machine output, also improve the degree of stretching of cotton fiber simultaneously; Make after the combing sliver through postchannel process finally can spin out more than 60, the high grade yarn of gloss appearance, satisfy the comfortable dressing of people or some special demands thus.Thereby combing machine is spinning high grade yarn and blending product imperative equipment.
The main working parts and the function thereof of combing machine are following: the transmission of headstock transmission mechanism-execution complete machine; In the car carding mechanism-execution to combing, stretching, the impurity elimination of web, remove defect, remove short flannel etc.; Tailstock drafter-make sliver comingling drawing-off until moulding.
Nipper parts in the combing locomotive in the carding mechanism are one and are flat nipper; Under the driving of power drive mechanism, carry out reciprocal front and back and have a little motion up and down; Cooperate cylindrical the moving of nipper top that cotton, chemical fibre are fed forward times without number to cotton roller; Break, carry out work again with carrying.
The clamped plate motion of prior art is to rely on the toggle of parallel four connecting rods of a cover to realize; Front and back two fulcrums of nipper; Two support bars in bottom that are rotationally connected, support bar is rotationally connected with pedestal two fulcrums again, and two support bars in bottom are realized rotating and moving with crank and slide block again.A support bar constitutes the fork in the moving sets as frame, and by the motor-driven crank, the end forms toggle for the slide block that rotates on the fulcrum of another support bar.Uniform rotation by motor; The slide block that drives crank rotation and end rotates; The moving sets that slide block is formed forces another support bar as frame to swing back and forth; Because the effect of sliding pair makes that the action of frame support bar swing makes nipper also in one plane do periodically speed change reciprocating motion.
Though the configuration structure of prior art can satisfy the basic run action of nipper, along with continuous progressive raising of textile industry, along with the raising of the cotton chemical fibre being waited until material combing requirement; The raising of product quality; The swing of the actuation tongs plate axis of being realized by toggle is to realize through crank, slide block and sliding bar mechanism, and after mechanical dimension confirmed, the displacement of clamped plate motion, speed and acceleration were also promptly fixed; Can not arbitrarily adjust; Can not adapt to the requirement of slight change, therefore, the nipper transmission mechanism of prior art and mode are also unsatisfactory; The convenient nipper operation characteristic of adjusting is freely hoped to provide in this area, meets transmission device and mechanism that the more characteristic curves of simulation move.
Simultaneously, the crank connecting link kind of drive complex structure of prior art, difficulty of processing is big; Cost is high; Structure is huger, and bigger to vibration, the impact of equipment, the operation inertia that mechanical action brings is bigger; The precision of influence action and the service life of device, those skilled in the art hopes that also breakthrough change can be arranged.
(3) summary of the invention
The objective of the invention is to intend provides the toggle that does not adopt the traditional mechanical formula to carry out transmission, overcomes the deficiency that toggle brings, and overcoming can not be with a kind of nipper drive mechanism that processes raw material, technological requirement changes operation characteristic.
The objective of the invention is to realize through following technical scheme:
A kind of drive mechanism of combing machine nipper, a fulcrum of the nipper support bar that is rotationally connected with pedestal in bottom that is rotationally connected is characterized in that, through eccentric wheel, eccentric rotary connects another fulcrum of nipper by the moving runner of servomotor mechanism.
Adopt the present technique scheme, the curve data of being imported servomotor by computer decides the servomotor motion, by the rotational motion of servomotor mechanism moving runner; Through eccentric wheel; Form eccentric another axle head oscillating motion, the nipper that another axle head swing of eccentric wheel causes being rotationally connected with it also is oscillating motion, has realized the motion of nipper; The curve movement data of servomotor can be write change, make the motion of nipper also can change according to end user operator's the wish that requires.
Further; Said servomotor mechanism is two servomotors; Wherein an A servomotor is through an A servomotor gear and a planetary planet carrier gears engaged; Another B servomotor passes through planetary central gear and back planetary gear engagement, and preceding planetary gear is exported gear teeth meshing with driving again, drives the coaxial connection moving runner of the output gear teeth.
By the output of two servomotors, realize that through planetary wheel mechanism motion is synthetic, finally drive the tongs plate axis motion; Make nipper move by predetermined curve; Synthetic by two servomotors, bigger driving power both was provided, can satisfy the motion-promotion force needs of many group nippers on the combing machine; And the synchronous proposition specific (special) requirements that need not be in operation to two servomotors, the mechanical interference phenomenon can not appear.
Further, said servomotor mechanism is the coaxial output gear engagement of A servomotor gear and B servomotor gear with the moving runner of two servomotors.
The power that adopts two servomotors to provide is much higher than the separate unit servomotor; Make whole driving power improve; The motor gear A of two servomotors and motor gear B directly with the Driven by Coaxial gears engaged of moving runner, structure is very simple, it is low to install the input expense; And guarantee two input servomotors actions synchronously, be than the work that is easier to realize for existing computer technology.
The drive manner of said moving runner is that the rotate wheel shaft of driving wheel rotates.Realized by rotation being the transformation of swing through eccentric mechanism.
Advantage of the present invention and beneficial effect: drive clamped plate motion by servomotor control; Make nipper move by predetermined curve; The motion of this method servomotor is decided by the curve data of computer input servomotor; Therefore the track of the motion of nipper is adjustable, and the displacement of clamped plate motion, speed and acceleration also can change adjustment.This method helps clamped plate motion optimization, and designs simplification helps the raising of combing machine speed, the raising of carding quality.
The present invention is simple in structure, and handling ease is avoided and reduced the bigger operation inertia that the prior art mechanical action brings, and improves the precision of mechanism action and the service life of device.
