Description
(1) technical field
The present invention relates to relate in a kind of transmission device of textile machine, particularly spinning combing machine the transmission driving dynamic structure of nipper and detaching roller.
(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 of comb interlock machine output, also improve simultaneously the degree of stretching of fiber, make after the combing ribbon 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 ribbon 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, the reciprocal variable motion of the motion of cooperation cylinder, detaching roller etc. is fed forward cotton, hair, blend fibre repeatedly, break, carry out work again with carrying.
The speed change reciprocating motion of Purely mechanical has been adopted in the motion of the clamped plate motion of prior art or detaching roller, usually by the toggle of common electric machine driving device cam or parallel four connecting rods, be converted into by rotation that swing realizes.Though the configuration structure of prior art can satisfy the basic run action of nipper and detaching roller, but continuous progressive the raising along with textile industry, along with the raising that materials such as cotton chemical fibre are required combing, 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 swing-bar mechanism are realized, after mechanical dimension determines, the displacement of nipper or the motion of discrete roller, speed and acceleration are also promptly fixing, can not arbitrarily adjust, can not adapt to the requirement of slight change, therefore, the transmission mechanism of prior art and mode and unsatisfactory.
In recent years, only in spinning combing machine the transmission driving mechanism of detaching roller successfully to have adopted by servomotor be the type of drive of power, similar disclosed technology has " drive mechanism of cotton comber detaching roller ", application number 03116393.9, the reciprocating motion of the servomotor direct driving device performance period property of this type of public technology by having the electric cam function, adopted the power of a servomotor in this control mode as driving mechanism, servomotor is controlled by the program in the servo controller, and the operation characteristic curve that can change servomotor according to program is to satisfy the variation of detaching roller operation, adjusting needs, the operation excursion of raising equipment is finished more kinds, specification, the combing sliver that characteristic requires.Yet, check according to practice, if only adopt a servomotor as power source, obviously difficulty satisfies the present situation that the combing equipment speed of service improves day by day, but because the price of servomotor is relatively more expensive again, the economic input ratio of two servomotors of configuration is higher in spinning combing machine, and the servomotor relative power is less, even be equipped with two servomotors, on driving power, still have slightly inadequate sensation, be difficult to satisfy requirement at a high speed in the bigger occasion of rotary inertia, the speed of service of having to sometimes reduce, this can influence production efficiency again.
Technical problem to be solved by this invention is: the running orbit of its key position of transmission of existing spinning combing machine employing Purely mechanical is unadjustable, and adopts servomotor directly to drive, and the raising of the speed of a motor vehicle can be subjected to the restriction of servomotor characteristic again.So far, the technical merit of this area has to pace up and down in a dilemma, all difficult desirable condition, along with different spinning process requirements is satisfied in the raising to the carding quality of ribbon, urgent hope can provide more economically a kind of, and the combing machine nipper that the energy free adjustment changes and the drives structure of detaching roller transmission have breakthrough changes and improvements.
