Description
Technical field
The utility model relates to twin-screw extrusion equipment fault detection technique fields, and in particular to a kind of twin-screw extrusion is set
Standby middle shaft coupling takes off axis fault detection system.
Background technique
Twin-screw extrusion equipment (double screw extruder) is on the basis of single screw extrusion equipment (single screw extrusion machine)
Grow up, since it has the characteristics that good charging performance, mixing plasticizing capacity, exhaust performance, extrusion stability, mesh
Before have been widely used in the modified processing of high molecular material.
Currently, the input shaft of twin-screw extrusion equipment generally passes through the driving axis connection of shaft coupling and transmission case.In reality
During charging operating, when load torque mutation, the stability of shaft coupling connection is vulnerable to influence, it may be assumed that shaft coupling occurs
The failure of de- axis.After the de- axis of shaft coupling occurs, if shutting down not in time, feeding equipment will continue feeding, cause machine jams and original
Material waste, machine cleaning take time and effort very much；Main motor remains in operation, and may cause the device on shaft coupling and flies out and hurts sb.'s feelings.It is existing
Have in technology, in order to avoid the generation of the problem, usually improves the frequency of equipment maintenance, manpower consuming is larger, simultaneously
By the continuous observation device operating status of people, do not have timeliness.In addition, when what detection also easily occurred that shaft coupling bursts apart not in time asks
Topic.
Utility model content
The purpose of this utility model is to provide shaft couplings in a kind of twin-screw extrusion equipment to take off axis fault detection system, with
Solve the problems, such as to refer in above-mentioned background technique in order to avoid in twin-screw extrusion equipment shaft coupling burst apart it is related go out, and take
The mode of equipment maintenance frequency is improved, manpower expends larger and detection not in time or presence easily occurs what shaft coupling burst apart
Problem.
To achieve the above object, the utility model provides the following technical solutions: shaft coupling in a kind of twin-screw extrusion equipment
De- axis fault detection system, including be installed on shaft coupling several induction original parts, for detect incude original part close to switch
And controller；It is described to be fixedly arranged on supporting bable tops close to switch, and will test signal and be transmitted to controller；The controller passes through
The operating of the detection signal control twin-screw extrusion equipment obtained close to switch.
Further, the induction original part is screw.
Further, the induction original part is 1.
Further, the alarm of alert bright sound is issued when further including shaft coupling failure, the alarm is installed on twin-screw
On extrusion equipment.
It further, further include current sensor for detecting electric current in twin-screw extrusion equipment circuit, the electric current
Sensor will test data and be transmitted to controller.
Compared with prior art, the utility model has the beneficial effects that
(1) using close switch real-time detection shaft coupling revolving speed, and judge whether shaft coupling is in de- axis failure shape accordingly
State can not only further appreciate that the trend of screw speed variation, can also reduce manpower consuming, the timeliness of real-time detection compared with
It is good；
(2) the real-time Acquisition Circuit electric current of current sensor is used, long-term follow, analysis can be changed to apparatus of load, in turn
Realize the judgement to the runnability, the working condition of shaft coupling of equipment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- drive shaft, 2- transmission case, 3- screw, the close switch of 4-, 5- input shaft, 6- twin-screw extrusion equipment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1: referring to Fig. 1, the utility model provides a kind of technical solution: shaft coupling in a kind of twin-screw extrusion equipment
Device takes off axis fault detection system, including be installed on shaft coupling 1 induction original part, for detect incude original part close to switch
4 and controller；
The induction original part is screw 3；
It is described to be fixedly arranged on supporting bable tops close to switch 4, and will test signal and be transmitted to controller；The controller passes through
The operating of the detection signal control twin-screw extrusion equipment 6 obtained close to switch 4.
Working principle:
(1) drive shaft 1 of transmission case 2 is connect by shaft coupling with the input shaft 5 of twin-screw extrusion equipment 6, and by spiral shell
Silk 3 is fixed on shaft coupling；
(2) whenever shaft coupling one circle of rotation, close to the transmittable pulse out of switch 4 to controller, the controller
Calculate the revolving speed of shaft coupling (the detection signal close to switch 4 is relatively stable reliable)；
(3) controller is judged according to revolving speed, described when the revolving speed of shaft coupling is in certain normal range
Axis device stable connection；When the revolving speed of shaft coupling is not in normal setting range, the shaft coupling is likely to be at de- axis failure shape
State need to be overhauled, and the function of the working condition of real-time monitoring shaft coupling is realized.
In addition, the detection system issues the alarm of alert bright sound, the alarm installation when can also increase shaft coupling failure
In in twin-screw extrusion equipment 6, when shaft coupling is in de- axis malfunction, alert bright sound is issued；
The real-time acquisition of size of current, the detection system can also add when operating to realize to twin-screw extrusion equipment 6
For detecting the current sensor of electric current in 6 circuit of twin-screw extrusion equipment, setting no-load current (does not have object in the controller
Electric current when material), off-axis electric current (shaft coupling is in electric current when de- axis failure)；
The detection signal of current sensor is compared by the controller with no-load current, off-axis electric current, when with zero load
When electric current is identical, controller control whole system shuts down, and realizes the effect of energy-saving protective；When identical as off-axis electric current,
Control alarm equipment alarm prompt；The controller is also recordable and stores current values when twin-screw extrusion equipment 6 operates, and
Shaft coupling is taken off to the load current record reservation before and after axis failure, is used as reference data so as to subsequent.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that can these embodiments be carried out with a variety of variations, repaired in the case where not departing from the principles of the present invention and spirit
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
