Description
(1) technical field
The utility model is a kind of power transmission arrangment of textile industry combing machine roller, particularly relates to the combing machine roller is carried out transmission by servomotor a kind of structure-improved.
(2) background technology
Known, in order to improve the quality of chemical fibre cotton woolen knitwear, important operation combing sliver in Textile Engineering, to remove impurity and the fault in the cotton spinning engineering semi-products, and eliminating short flannel, make in the combing sliver of making straightening of fibers parallel, gloss appearance, it is spinning high grade yarn and blending product imperative equipment.
The main working parts and the function thereof of combing machine are as follows: drafter, be generally the pneumatic type drafting system of iterate, and the traction sliver moves ahead; Machine is fed part, and the roller device of continous mode feeding lap can not be out of shape when making the lap feeding, can put in place rapidly during backup roll; The nipper part, nipper mechanism is controlled respectively each rank cotton fiber, and nipper rests on the front position to keep the clamping fiber not sagging when machine stops; Circle comb section part with certain and combing angle combing sliver, is set the cleaning time and the cleaning frequency of circle comb.The top comb parts reach high efficiency and top comb that high-quality possessed for guarantee producing, and be furnished with the compressed air automatic nozzle automated cleaning is carried out in top comb, and the fibre bundle that accumulates in the top comb part is cleared up; Detaching roller, supporting with roller, pneumatic pressurization makes the fiber after combing combine with web; Web is carried and slivering, makes web aggregate into uniform strip, and discerning indivedual combing heads has not problem, even identification adds the fault that may produce man-hour.The air draught parts, noil and air-flow are concentrated in the center tube simultaneously.
Detaching roller in the combing machine is that each is a pair of by front and back, and the roller shape roller of the transmission that is meshing with each other is up and down formed, between two detaching rollers of front and back upside by driving rolls engagement carrying out transmission.Driving rolls must carry out backward and forward in conjunction with complete equipment, and back and forth rotation at interval to cooperate follow-up nipper action, both separated tear fracture with continuous bar, follow-up sliver can be stacked step by step involve slivering.
The spinning movement of driving rolls has certain requirement, original technology is by driven by motor one cam mechanism, form and to change direction before and after periodic and the rotation of speed, but facts have proved through long-term the use, in the drive actions of detaching roller, wish to have the increase more flexibility, to adapt to different cotton raw materials, therefore the requirement of a different cotton grade can not satisfy the needs of product processing with simple cam mechanism.
Later on a kind of technical scheme by driving rolls in the middle of the driven by servomotor proposes and discloses, a kind of drive mechanism of cotton comber detaching roller, by servomechanism with electric cam function, detaching roller and main shaft constitute, described have the servomechanism of electric cam function by servo motor, servo-driver and host computer constitute, the input port of described servo-driver is connected with described host computer, output port is connected with the signal controlling port of described servo motor, the output shaft of described servo motor is provided with a drive, end at described detaching roller is provided with a pair of drive simultaneously, drive on the described servo motor output shaft is gear that is meshed or the profile of tooth belt wheel that is meshed by cog belt with drive on the described detaching roller, and the output shaft of described servo motor and main shaft start-stop are synchronous.This technical scheme can improve the quality and the operating efficiency of web owing to used the servomechanism with electric cam function.
But, to drive of the motion of two components simultaneously by putting into practice a servomotor from roller, the maximum characteristic of servo-drive system can't 350 pincers/minute with on drive detaching roller by the motion of required curve movement, make the speed of digitlization combing machine placed restrictions on 350 pincers/minute below, be difficult to the output requirement that reaches desirable.A servomotor drives two components from roller, three drives, two shaft couplings, driving torque is big, power of motor is big, meshing point in the transmission is many, low precision, the processing of mechanism and installation requirement height, wearing and tearing are big, life-span is short, therefore is necessary the combing machine transmission mechanism that is driven by a servomotor is further improved.
(3) summary of the invention
The purpose of this utility model is to intend a kind of raising driven by servomotor power is provided, and adopts the structure of two driven by servomotor combing machine rollers.
The purpose of this utility model is achieved through the following technical solutions:
A kind of servomotor driving improving structure of combing machine detaching roller comprises:
Two servomotors of input side;
Detaching roller, back detaching roller wheel connected the back detaching roller before the preceding detaching roller wheel of outlet side connected;
The centre is the planetary gear of being made up of planet carrier, planetary gear A, planetary gear B and central gear;
It is characterized in that, servomotor is by the planet carrier gears engaged of pinion and planet carrier, another servomotor is by central gear and planetary gear B engagement, and planetary gear A meshes with driving output wheel again, drives output wheel through coaxial driving rolls and the engagement of forward and backward detaching roller wheel.
Further, described driving output wheel and central gear concentric.
Further, the power of described servomotor is 1 to 25 kilowatt.
Adopt the technical program, two servomotors, wherein servomotor is by the planet carrier gears engaged of pinion and planet carrier, another servomotor is by central gear and planetary gear B engagement, planetary gear A on the same planet carrier meshes with driving output wheel again, drives output wheel through coaxial driving rolls and the engagement of forward and backward detaching roller wheel.Synthetic by two servomotors, bigger driving power both was provided, satisfy the rotary power needs of combing machine roller, control the forward and reverse rotation that synthetic generation needs and the variation of velocity of rotation again.
Advantage of the present utility model and beneficial effect: need to drive multicomponent from roller on combing machine driving shaft in the textile machine, need the power of consumption very big, adopt the technical program both to solve power, realized the direction and the rotation speed change of rotating again.In actual motion.With a servomotor is the main power that drives, at peak acceleration and speed place, add the input power of another servomotor, make whole driving power can not overload, can reach 450 pincers/minute with on drive detaching roller operation, improved the output of processing.
The utility model adopts digital driven by servomotor mechanism, and rotation changes than original the driving with mechanical cam mechanism greater flexibility, handles the better quality of cotton formation sliver, and the cloth that weaves is also better; The power that adopts two servomotors to provide is much higher than the separate unit machine, makes production more stable.
The utility model adopts two servomotors, and the not synchronous proposition specific (special) requirements that two servomotors are in operation can not produce and drives a forward and backward detaching roller of cover simultaneously and the mechanical interference phenomenon occurs.
