Description
Technical field
The utility model relates to belt conveyor system field more particularly to a kind of belt conveyor system protective devices.
Background technique
During belt conveyor conveys material, since material specific gravity is larger, belt usually will appear slipping phenomenon.Belt
Skidding will cause sliding friction between belt and leather belt roller, cause to wear, and influence belt and leather belt roller service life.In addition, belt slippage
Then the material on belt cannot convey in time, and feeding device or previous stage belt conveyor still send material, cause to skid
Material accumulation and unrestrained on belt, causes material waste, and influence belt conveyor surrounding enviroment and increase cleaning works amount.
Utility model content
Technical problem to be solved by the utility model is: Belt Conveying can be stopped in belt slippage in time by providing one kind
The belt conveyor system protective device of machine.
In order to solve the above problem the technical solution adopted is that: belt conveyor system protective device includes belt conveyor, skin
Band conveyer include conveyor belt, further include master control switch and feedback device, master control switch at least with belt conveyor and feedback
Device is electrically connected and can control the operation and stopping of belt conveyor and feedback device；Feedback device includes signal wheel and signal
Wheel sensor, signal wheel are bonded with the lower surface of conveyor belt active section, and signal wheel sensor detects the revolving speed of signal wheel；Work as letter
Number wheel speed is zero or when lower than setting value, and signal wheel sensor issues signal control master control switch and disconnects.
Further, feedback device includes time-delay relay, time-delay relay controls signal wheel sensor delayed startup.
Further, belt conveyor system protective device includes at least two belt conveyors, feedback device and belt
Conveyer is arranged in a one-to-one correspondence.
The beneficial effects of the utility model are: (1) signal wheel by the frictional force drives between belt, works as belt slippage
When, belt stops or movement speed reduces, and signal wheel also accordingly stops or revolving speed reduces；Signal wheel sensor detects signal wheel
Revolving speed；When signal wheel speed is zero or is lower than setting value, signal wheel sensor issues signal control master control switch and disconnects, thus
Stop the belt conveyor skidding, protects belt conveyor.
(2) master control switch connect with feeding device, or when with multiple belt conveyors, master control switchs defeated with all belts
Machine is sent to connect；When a belt conveyor skids, master control switch can control feeding device and all belt conveyors stop,
To stop being fed to skidding belt, material accumulation on skidding belt is prevented, avoids material unrestrained.
Detailed description of the invention
Fig. 1 is belt conveyor system protective device structural schematic diagram；
Fig. 2 is feedback device structural schematic diagram；
In the figure, it is marked as belt conveyor 1, conveyor belt 11, feeding device 2, master control switch 3, feedback device 4, signal
Take turns 41, signal wheel sensor 42, time-delay relay 43.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
A kind of can stop in time in belt slippage to the protection of the belt conveyor system of skidding Belt Conveying material is provided
Device, as depicted in figs. 1 and 2: belt conveyor system protective device includes belt conveyor 1, and belt conveyor 1 includes conveying skin
Band 11, further includes master control switch 3 and feedback device 4, and master control switch 3 is at least electrically connected simultaneously with belt conveyor 1 and feedback device 4
The operation and stopping of belt conveyor 1 and feedback device 4 can be controlled；Feedback device 4 includes that signal wheel 41 and signal wheel sense
Device 42, signal wheel 41 are bonded with the lower surface of 11 active section of conveyor belt, and signal wheel sensor 42 detects the revolving speed of signal wheel 41；
When 41 revolving speed of signal wheel is zero or is lower than setting value, signal wheel sensor 42 issues signal control master control switch 3 and disconnects.
" master control switch 3 is at least electrically connected with belt conveyor 1 and feedback device 4 " refer to master control switch 3 in addition to belt
Outside conveyer 1 and feedback device 4 are electrically connected, it can also be connect with the other equipment of the equal belt conveyor systems of feeding device 2.
Signal wheel 41 passes through the frictional force drives between conveyor belt 11, when conveyor belt 11 is skidded, conveyor belt 11
Stop or movement speed reduces, signal wheel 41 also accordingly stops or revolving speed reduces；Signal wheel sensor 42 detects signal wheel 41
Revolving speed；When 41 revolving speed of signal wheel is zero or is lower than setting value, it is disconnected that signal wheel sensor 42 issues signal control master control switch 3
It opens, to stop the belt conveyor 1 to skid, protects belt conveyor 1.
Belt conveyor system protective device can also have the skin of multiple phases " series connection " with only one belt conveyor 1
Band conveyer 1, when there is multiple belt conveyors 1, feedback device 4 is arranged in a one-to-one correspondence with belt conveyor 1, in this way can be right
Each belt conveyor 1 is protected.
Master control switch 3 is connect with feeding device 2, or when having multiple belt conveyors 1, master control switch 3 and all belts
Conveyer 1 connects；When a belt conveyor 1 skids, master control switch 3 can control feeding device 2 and all Belt Conveyings
Machine 1 stops, to stop being fed to the conveyor belt 11 of skidding, prevents material accumulation in the conveyor belt 11 skidded, avoids object
Material is unrestrained.
Master control switch 3, which controls belt conveyor 1, to be stopped, and is carried out after handling exclusion slipping phenomenon, and belt conveyor system needs
It is again started up.The initial stage that belt conveyor system is again started up, conveyor belt 11 may not be able to effectively driving signal wheel 41 rotate,
At this time if signal wheel sensor 42 brings into operation, due to detecting that signal wheel 41 stops or revolving speed is insufficient, and can control total
It controls switch 3 to disconnect, causes cancel closedown.In order to avoid above situation, feedback device 4 includes time-delay relay 43, and be delayed relay
Device 43 controls 42 delayed startup of signal wheel sensor.
