Description
(1) technical field
The present invention is a kind of nipper modular construction of textile industry combing machine, particularly relates to the power drive structure 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 is to remove wherein staple fibre, impurity, cotton knot and fault etc. by combing by the carded sliver web of carding machine output, also improve simultaneously the degree of stretching of cotton fiber, make after the combing sliver by 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 as follows: 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 motion slightly up and down, cooperate cylindrical the moving of nipper top that cotton, chemical fibre are fed forward repeatedly 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 is as the fork in the frame formation moving sets, 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, but continuous progressive the raising along with 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 pass through crank, slide block and sliding bar mechanism are realized, after mechanical dimension determines, the displacement of clamped plate motion, speed and acceleration are also promptly fixing, 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 wished 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, the cost height, 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 wishes that also breakthrough change can be arranged.
(3) summary of the invention
The objective of the invention is to intend providing not adopting traditional mechanical toggle to carry out transmission, overcome the deficiency that toggle brings, 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 be achieved through the following technical solutions:
A kind of drives structure of combing machine nipper, a fulcrum of the nipper support bar that is rotationally connected with pedestal in bottom that is rotationally connected, it is characterized in that another fulcrum of nipper another root support bar of bottom that is rotationally connected, the wobble wheel of the fixedly connected servomotor in the lower end of support bar mechanism.
Adopt the technical program, curve data by computer input servomotor is controlled the servomotor motion, the wobble wheel of servomotor mechanism reciprocally swinging back and forth causes fixedly connected with it support bar and the nipper that is rotationally connected also is oscillating motion, 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, described servomotor mechanism is two servomotors, wherein an A servomotor is by an A servomotor gear and a planetary planet carrier gears engaged, another B servomotor is by planetary central gear and back planetary gear engagement, preceding planetary gear is exported gear teeth meshing with driving again, drives the coaxial connection wobble wheel of the output gear teeth.
Output by two servomotors, realize that by planetary wheel mechanism motion is synthetic, the final tongs plate axis that drives moves, 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 do not need synchronous proposition specific (special) requirements that two servomotors are in operation, the mechanical interference phenomenon can not appear.
Further, described servomotor mechanism is the A servomotor gear of two servomotors and B servomotor gear and the coaxial output gear engagement of wobble wheel.
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 are directly and the Driven by Coaxial gears engaged of wobble wheel, structure is very simple, device input expense is low, and guarantee two input servomotors actions synchronously, be than the work that is easier to realize for existing computer technology.
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 bigger operation inertia and vibration that the prior art mechanical action brings, improves the precision of mechanism action, the service life of extension fixture.
