Abstract
The utility model mainly discloses a swing frequency control device of a grooved drum frequency converter of a draw texturing machine, comprising a microprocessor chip, a communication interface, an intermediate relay, and a grooved drum frequency converter, wherein the microprocessor chip is connected with the grooved drum frequency converter by the communication interface; the microprocessor chip is simultaneously connected with the grooved drum frequency converter by the intermediate relay; the microprocessor chip sends a signal to a coil of the intermediate relay so as to control the work state of contact points of the middle relay. The device disclosed by the utility model realizes continuous data exchange with the frequency converter by taking the microprocessor chip as a host computer, so that the frequency converter operates as required; the device disclosed by the utility model not only has strong anti-interference ability, but can also finish complex frequency change quickly.
Description
Technical field
The utility model relates to elasticizer manufacturing technology field, and is relevant through the fast-changing elasticizer groove drum of serial communication interface control of conversion device frequency frequency converter wobble frequency control device with the use single-chip microcomputer especially.
Background technology
In elasticizer manufacturing field, overlap in order to prevent silk, reach unwinding effect better; Groove drum need ceaselessly be done acceleration; Retarded motion forms moving wave shape as shown in Figure 2, and what pay special attention to is not fluctuating of groove drum speed long period; The part silk is overlaped, the back road unwinding effect of influence silk.
At present, this motion of control generally has two kinds of schemes:
1. accomplish (switch, or frequency converter wobble frequency function) through the function of frequency converter self like external signal control multistep frequency;
2. given through external analog amount signal (like 0 ~ 10V standard signal, 4 ~ 20 milliamperes of standard signals etc.), the control of conversion device is accomplished.
In order to address the above problem, the inventor designs elasticizer groove drum frequency converter wobble frequency control device, and this case produces thus.
The utility model content
The fundamental purpose of the utility model provides a kind of elasticizer groove drum frequency converter wobble frequency control device; Uninterrupted and frequency converter carries out exchanges data through host computer; Frequency converter is moved as requested, and the existing very strong antijamming capability of the utility model also can be accomplished complicated change of frequency fast.
In order to achieve the above object, the utility model is realized through following technical scheme:
A kind of elasticizer groove drum frequency converter wobble frequency control device comprises little process chip, communication interface, auxiliary reclay, groove drum frequency converter; Little process chip connects the groove drum frequency converter through communication interface, and little process chip connects the groove drum frequency converter through auxiliary reclay simultaneously, and little process chip is sent the coil that signal is given auxiliary reclay, the duty of control auxiliary reclay contact.
After adopting such scheme, little process chip can calculate the frequency values of groove drum frequency converter in the utility model, sends in the groove drum frequency converter through communication interface; As long as the groove drum frequency converter can be accepted data, auxiliary reclay is accepted the signal of little process chip, changes duty; Control groove drum frequency converter, the The whole control mode is more stable, and is reliable; Can fast, accurately control the change of frequency of groove drum frequency converter, have very high using value.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the start and stop synoptic diagram of elasticizer groove drum frequency converter in the utility model preferred embodiment.
Embodiment
In conjunction with accompanying drawing, preferred embodiment explains further details to the utility model.
A kind of elasticizer groove drum frequency converter wobble frequency control device comprises little process chip 1, communication interface 2, auxiliary reclay 3 and groove drum frequency converter 4.Little process chip 1 connects groove drum frequency converter 4 through communication interface 2, and little process chip 1 connects groove drum frequency converter 4 through auxiliary reclay 3 simultaneously, and little process chip 1 is sent the coil that signal is given auxiliary reclay 3, the duty of control auxiliary reclay 3 contacts.
As shown in Figure 1; Little process chip 1 is according to the motion mathematical model (Fig. 2) of groove drum frequency converter 4; Regularly calculate the frequency values of groove drum frequency converter 4; According to the communications protocol of frequency converter standard, through communication interface 2 frequency values is sent in the groove drum frequency converter 4, groove drum frequency converter 4 is changed as requested fast.
In design, because the frequency of groove drum frequency converter 4 is engraved in variation when being.For the difficulty of simplified system, improve the response speed of system, little process chip 1 can only not stopped paying out and sent frequency order as host computer, need not receive replying of groove drum frequency converter 4.
As shown in Figure 2, little process chip 1 is sent the coil that signal is given auxiliary reclay 3, the disconnection of control auxiliary reclay 3 contacts, closure.Auxiliary reclay 3 contacts are broken off, and groove drum frequency converter 4 is out of service; Auxiliary reclay 3 closings of contact, groove drum frequency converter 4 brings into operation.
The whole control of the utility model is more stable, and is reliable, can be quick, accurately control the change of frequency of groove drum frequency converter, and have very high using value.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
Claims (1)
1. an elasticizer groove drum frequency converter wobble frequency control device is characterized in that: comprise little process chip, communication interface, auxiliary reclay, groove drum frequency converter; Little process chip connects the groove drum frequency converter through communication interface, and little process chip connects the groove drum frequency converter through auxiliary reclay simultaneously, and little process chip is sent the coil that signal is given auxiliary reclay, the duty of control auxiliary reclay contact.
