Technical field
The utility model belongs to Weaving device automatic control technology field, relates to a kind of improvement of carding machine control device, is a kind of carding machine carded sliver weight control device specifically.
Background technology
Comb and parallel cotton fibers prior to spinning is the preceding working procedure of spinning, and the fragment length weight of the output products of carding machine---the carded sliver is that the carded sliver uniformity is the important indicator that is related to subsequent product yarn and even cloth quality, and the control of carded sliver weight is mainly implemented on carding machine.In the prior art, be the thickness of output sliver behind thickness by detect giving the cotton layer of feeding before the cotton roller and the large pressuring roller, through the calculating of the neat and well spaced device of length fragment, regulate that the frequency of the frequency converter of using to the cotton roller electric machine controller realizes.Under ordinary production speed, this method can make carded sliver weight be well controlled, but has following problem in carding machine lifting speed process: the carding machine transfer amount is on the low side relatively in the boosting velocity procedure, light partially 2～3 gram/rice of carded sliver weight; The carding machine transfer amount is on the high side relatively in the reduction of speed process, and carded sliver weight lays particular stress on 3～5 gram/rice.Adopt the control accuracy of frequency converter low, speed responsive is slower.This is ubiquity and the technical problem that needs to be resolved hurrily in the present carding machine.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of carding machine carded sliver weight control device is provided, and makes carding machine its output carded sliver weight in lifting speed process also can be controlled at setting value effectively, the control accuracy height, and speed responsive is fast.
The purpose of this utility model is achieved through the following technical solutions:
A kind of carding machine carded sliver weight control device, comprise the cotton layer of feeding detecting unit, the output sliver detecting unit, the neat and well spaced device of length fragment, central controller, give cotton roller motor and controller thereof, doffer's motor and controller thereof, it is characterized in that: described to give cotton roller motor and controller thereof and doffer's motor and controller thereof all be servomotor and controller thereof, give on the cotton roller servomotor and be equipped with to the cotton roller revolution detector, doffer's revolution detector is installed on doffer's servomotor, be connected to the cotton roller servomotor controller for the output signal of cotton roller revolution detector, the output signal of doffer's revolution detector is connected to doffer's servomotor controller, give cotton roller servomotor controller and doffer's servomotor controller respectively with the neat and well spaced device of length fragment, central controller connects.
To improvement of the technical scheme: described to give cotton roller revolution detector and doffer's revolution detector all be rotary encoder.
To further improvement in the technical proposal: describedly adopt the CAN communication for the connection between cotton roller servomotor controller, doffer's servomotor controller, the neat and well spaced device of length fragment, the central controller.
The utility model compared with prior art has following advantage and good effect:
It all is servomotor and controller thereof that the utility model is given cotton roller motor and controller thereof and doffer's motor and controller thereof, give on cotton roller servomotor and the doffer's servomotor and be separately installed with to cotton roller revolution detector and doffer's revolution detector, be connected to the cotton roller servomotor controller for the output signal of cotton roller revolution detector, the output signal of doffer's revolution detector is connected to doffer's servomotor controller.Be connected for the cotton roller servomotor controller respectively with the neat and well spaced device of length fragment, central controller with doffer's servomotor controller.Can in servo controller, embed special-purpose operation curve,,, accurately control thereby reach the omnidistance of the carded sliver by the total line traffic control doffer of CAN and to the servo method of operation of cotton roller according to the judgement of doffer's running status.Adopt the CAN communication, the control accuracy height, speed responsive is fast, can make the carded sliver deviation of weight of doffer in lifting speed process be controlled at ± 5%/5 meter within, reach user's instructions for use.
