Abstract
The utility model discloses a cracked rollover valve of detectable chain, including rollover valve casing, rollover valve case, axis of rotation, inductance type proximity switch, detector, relay, PLC and motor rotate, the rollover valve case passes through the axis of rotation to be fixed in the rollover valve casing, be equipped with the rollover valve sprocket in the axis of rotation, the motor passes through the chain and drives the rollover valve sprocket and then make the axis of rotation rotate, the detector is rotated in the installation in the axis of rotation, inductance type proximity switch installs on the rollover valve casing, the horizontal detection distance who rotates between detector and the inductance type proximity switch is 10mm, inductance type proximity switch links to each other with the relay, the relay links to each other with PLC. This rollover valve rotates the detector through inductance type proximity switches detect rollover valve and whether determines rollover valve in normal work in the rotation to determine the chain and whether split, and then whether the decision avoids putty influence production through PLC warning stopping feeding.
Description
Technical field
This utility model is related to a kind of roll-over valve, specifically a kind of roll-over valve of detectable chain breakage.
Background technology
Existing upset valve system, chain breakage easily occur causes the phenomenon of putty, and main cause is that chain wear is reached
There is fracture in strength degree, motor still in operation, but and can not find in time, add and continue above charging and cause putty.When
Between it is long, stockpile above gets up to affect the normal operation of above feed system, affects production yields.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of roll-over valve of detectable chain breakage, can not only
It is enough to find whether roll-over valve chain ruptures in time, moreover it is possible to and alarm stops charging and avoids putty from affecting production.
The technical solution adopted in the utility model is：A kind of roll-over valve of detectable chain breakage, including upset valve body,
Roll-over valve rotary shaft, inductance approach switch, rotation detector, relay, PLC, power supply and motor, the roll-over valve rotary shaft
Through upset valve body, its one end is provided with rotation detector, and the other end is connected with sprocket wheel, and the motor passes through chain-driving chain
Wheel so make roll-over valve rotary shaft rotate, the inductance approach switch be arranged on upset valve body top and with relay phase
Even, the relay is connected with PLC, and the power supply connects inductance approach switch and relay, the rotation detector and electricity
Horizontal detection distance between sense formula proximity switch is 10mm.
The beneficial effects of the utility model are：The roll-over valve detects roll-over valve rotation detector by inductance approach switch
Whether rotating judging roll-over valve whether in normal work, so as to judging whether chain ruptures, and then decide whether to pass through
PLC warnings stop charging and avoid putty from affecting production.Therefore the roll-over valve can in time find whether roll-over valve chain ruptures, energy
Enough timely stopping alarms.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1, roll-over valve rotary shaft, 2, rotation detector, 3, inductance approach switch, 4, power supply, 5, relay, 6,
PLC, 7, chain, 8, motor, 9, upset valve body, 10, sprocket wheel.
Specific embodiment
In order to deepen to understanding of the present utility model, make into one to of the present utility model below in conjunction with embodiment and accompanying drawing
Step is described in detail, and the embodiment is only used for explaining this utility model, does not constitute the restriction to protection domain of the present utility model.
As shown in figure 1, a kind of roll-over valve of detectable chain breakage, including upset valve body 9, roll-over valve rotary shaft 1, electricity
Sense formula proximity switch 3, rotation detector 2, relay 5, PLC 6, power supply 4 and motor 8, roll-over valve rotary shaft 1 passes through roll-over valve
Body 9, its one end is provided with rotation detector 2, and the other end is connected with sprocket wheel 10, motor 8 by chain 7 with movable sprocket 10 further
Rotate roll-over valve rotary shaft 1, inductance approach switch 3 is arranged on the top of upset valve body 9, rotation detector 2 and inductance
Horizontal detection distance between formula proximity switch 3 is 10mm.The white wire of inductance approach switch 3 and black line respectively with power supply 4
24+ be connected with 24-, the blue line of inductance approach switch is connected with 14 points of relay 5, No. 13 points of relay 5 and electricity
The 24+ in source 4 is connected, and No. 5 points of relay 5 are connected with the i100.0 of PLC, and No. 9 points of relay 5 are connected with the 24+ of PLC.
Operation principle：When chain is intact, motor operation, roll-over valve rotary shaft is rotated, and rotary shaft drives rotation detector to turn
Dynamic, inductance approach switch receives the signal of rotation detector.Inductance approach switch gives PLC by relay signal.Cause
It is 3 seconds to pass on detector and turning around, by programming to PLC, if the signal that also can't detect relay in 5 seconds, illustrates electricity
Sense formula proximity switch is confiscated signal, i.e. rotary shaft and is not turned, chain breakage, and at this time PLC stops motor operation, goes out alarm signal
Number, stop the operation of feed system above, prevent putty.
