In the process of running, often there is the phenomenon of tension force shakiness in traditional ribbon conveyer, to cause adhesive tape,
The damage of rack or tensioning apparatus；Especially in power-off or shutdown, tension force shakiness easily causes equipment damage.
All more or less there is problem in existing belt stretcher：Such as heavy-hammer-tightening or hydraulic tensioning device, due to
Its adjustable range is small, corresponding speed is slow, can not be suitable for large conveying quantity at all, the scalable love of extra long distance is the work of conveyer
Condition.Although having occurred variable frequency tensioning device now, existing variable frequency tensioning device need by tension sensor into
The tension feedback of row belt and it is necessary to tension be kept by brake, therefore failure rate is higher, and control complicated, tune
Section precision is low, and corresponding speed is slow, and cost is also relatively high.
Utility model content
One of the purpose of this utility model is to provide a kind of of low cost, simple in structure, easy to control and accurate, response
Fireballing Novel belt tensioning control device.
The two of the purpose of this utility model are to provide a kind of ribbon conveyer including Novel belt tensioning control device.
This Novel belt tensioning control device provided by the utility model, including controller, frequency converter, tensioning motor,
Steel wire rope and strand band machine, further include contactor, and it is permanent magnet synchronous motor to be tensioned motor；Power input by frequency converter and
The input terminal of contacts of contactor connection tensioning motor；Controller connects the control terminal of the control terminal and contactor of frequency converter；Control
Device sends out control signal to frequency converter, and control frequency converter controls tensioning motor by contacts of contactor, to ensure skin
The rate of tension of band.
The Novel belt tensioning control device further includes man-machine interface；Man-machine interface is connect with controller, for grasping
Make personnel and control instruction is issued to controller by man-machine interface.
The controller is PLC, Special industrial controller, microcontroller or DSP.
Breaker is also serially connected between the input terminal of the power input and frequency converter, breaker is for protecting frequency conversion
Device.
The contactor is the contactor with the normally opened node of two-way and the normally closed node of two-way；The control terminal of contactor with
Controller connects, and the normally opened node of two-way of contactor is serially connected with the arbitrary two-way input terminal of tensioning motor respectively, and the two of contactor
The normally closed node in road is connected to respectively between the arbitrary two-way input terminal of tensioning motor；Such connection type and the contactor of effect are
To seal star contactor.
The utility model additionally provides a kind of ribbon conveyer including the Novel belt tensioning control device.
This Novel belt tensioning control device and its ribbon conveyer provided by the utility model, it is same by using permanent magnetism
Motor is walked as tensioning motor, while simply but cleverly circuits improvement will be passed through in envelope star contactor access device so that
Tight motor does not need the braking of brake during belt tension is kept, and ensure that power failure etc. in special circumstances
The tension of conveyer belt, to ensure that the reliability of system；In addition, the utility model also has of low cost, simple in structure, control
The advantages that system is convenient and accurate, fast response time.
Description of the drawings
Fig. 1 is the functional block diagram of the utility model.
Fig. 2 is the circuit diagram of the utility model.
Specific implementation mode
It is the functional block diagram of the utility model as shown in Figure 1：Power input is connected by frequency converter and contacts of contactor
Connect the input terminal of tensioning motor；Controller connects the control terminal of the control terminal and contactor of frequency converter；Controller sends out frequency converter
Go out and control signal, control frequency converter controls tensioning motor by contacts of contactor, and tensioning motor passes through steel wire rope and strand
Ensure the rate of tension of belt with machine；Man-machine interface is connect with controller, for operating personnel by man-machine interface under controller
Send out control instruction；Controller is PLC, Special industrial controller, microcontroller or DSP.
It is illustrated in figure 2 the circuit diagram of the utility model：Power input is connected by breaker (indicating K1 in figure)
The input terminal (R, S and T) of frequency converter is connect, any two ends (being the ends V and the ends W in figure) in the output end (U, V and W) of frequency converter are each
From after the normally opened node (indicating KM-1 and KM-2 in figure) by contactor, (motor M must use permanent magnetism to connection tensioning motor M
Synchronous motor)；In addition, (being the ends U and V and the ends V and W in figure) is by connecing between any two ends of the output end of frequency converter
Normally-closed contact (KM-3 and KM-4 is indicated in figure) short circuit of tentaculum；The control coil KM of contactor then connects the control of controller
End；The control terminal of frequency converter also connects controller simultaneously.The effect of contactor is to seal star contactor.
This Novel belt tensioning control device provided by the utility model, it is necessary first to by of current of electric and belt
Power carries out calibration one by one (corresponding motor current value and belt tension value by experiment)；After system electrification, control
Device processed is powered on star contactor is sealed, and the normally opened node for sealing star contactor at this time is closed, and normally closed node disconnects, at this time controller according to
The tensile force requirement of belt feeder, directly assigns the control instruction of frequency converter, is controlled current of electric by frequency converter, pass through guarantor
Card is tensioned the current value of motor to carry out the tensioning of belt.
When needing to shut down, controller first exports control command control frequency converter and shuts down, and then disconnects envelope star contactor again.
When the unexpected loss of power accident occurs, system cut-off, seals the control terminal dead electricity of star contactor, at this time at this time
There are both ends to be disconnected with input end of motor in the output end of frequency converter, and be tensioned whole short circuits between the input terminal of motor, due to opening
Tight motor is using permanent magnet synchronous motor, therefore being tensioned motor being capable of rapid parking brake in input terminal short circuit.
The Novel belt tensioning control device of the utility model eliminates tension sensing compared with traditional tensioning apparatus
Device and brake, simple in structure, easy to control, precision is high, fast response time.
