Description
Technical field
The present invention relates to a kind of drum rotation speed measures and warning device.
Background technology
In tobacco cutting is produced, the application of cylinder kind equipment is general, relates to a plurality of operations such as loose, moisture regain, dry, perfuming.Drum rotation speed is an important parameter in technology for making tobacco threds, and according to the difference of trade mark formula, its rotating speed requires different, and the actual speed of cylinder also exerts an influence to the homogeneity of warming and humidifying, perfuming and loose ability.
At present, scrap prodn. line is taked open loop mode to the control of drum rotation speed more, according to technological requirement rotating speed, by frequency converter, exporting a fixed frequency controls, cannot monitor its actual speed, once Rolling motor, reductor or carrying roller are changed, be prone to and set the unmatched phenomenon of rotating speed, affect completing of technic index.For detecting in real time drum rotation speed, some enterprise adopts mirror reflection optoelectronic switch to detect the reflector plate mode on cylinder, and because reflector plate is with drum rotating, the jitter that causes optoelectronic switch to detect, exists undetected situation.Also have enterprise to adopt the equipment such as scrambler or Speed Controller be installed on drum electric arbor, however all exist install inconvenience, to existing equipment change large, control complicated shortcoming, lack corresponding warning processing capacity simultaneously.
Summary of the invention
The object of this invention is to provide and a kind of drum rotation speed is measured and warning device, real-time detection that can be to drum rotation speed, and the rotating speed fault that transfinites is sent to warning in time.
To achieve these goals, the present invention adopts following technical scheme: the device that a kind of drum rotation speed is measured and reported to the police, comprise cylinder, block rubber, optoelectronic switch, protective cover, controller and operation screen, block rubber sticks on the side surface of cylinder inlet end, optoelectronic switch is arranged on the fixed blade guard of cylinder inlet end, its induction ray and drum central axis line parallel, and height equates with block rubber, optoelectronic switch is electrically connected to controller, and controller is electrically connected to operation screen.
Compared with prior art, the present invention detects the block rubber with drum rotating by optoelectronic switch, send pulse signal, by supervisory system, calculated the gap periods of pulse signal, thereby draw cylinder actual speed, and with technique initialization rotating ratio, the rotating speed fault that transfinites is sent to warning in time, thereby rollers running performance is monitored in real time, is guaranteed the working ability of cylinder, have simple in structure, easy for installation, control accurate feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is systematic schematic diagram of the present invention;
In Fig. 1: 1, cylinder, 2, rubber blanket, 3, optoelectronic switch, 4, protective cover, 5, controller, 6, operation screen.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in Figure 1, the present invention includes cylinder 1 and block rubber 2, optoelectronic switch 3, protective cover 4 and controller 5 and operation screen 6, block rubber 2 sticks on the side surface of cylinder 1 inlet end, optoelectronic switch 3 is arranged on the fixed blade guard 4 of cylinder 1 inlet end, its induction ray is parallel with cylinder 1 central axis, and height equates with block rubber 2, makes the induction range of block rubber 2 in optoelectronic switch 3, optoelectronic switch is electrically connected to controller, and controller is electrically connected to operation screen.
Optoelectronic switch 3 can adopt diffuse reflection type optoelectronic switch, and block rubber 2 is its inductor, and block rubber 2 is highly 5CM, and distance is 2CM between the two.
In order to increase the robustness of system, operation screen is connected by Industrial Ethernet with controller.
Adopt block rubber as inductor, can avoid the welding connecting mode of metal sensing chip and cylinder, improve ease for use.
As shown in Figure 2, according to technological requirement, on operation screen, rotating speed is set in input, by transducer drive Rolling motor according to setting rotation speed operation.Because block rubber 2 is with cylinder 1 rotation, when block rubber 2 enters the induction range of optoelectronic switch 3, optoelectronic switch 3 is to controller input pulse signal, detects its time to be spaced apart t, and via controller calculates transient speed n=60/t, on operation screen, shows in real time.
The tolerance of setting drum rotation speed is ± 5%, and limit range is ± 20%, when 0.95n0≤n≤1.05n0, and cylinder safe handling.
When 0.8n0 < n < 0.95n0 or 1.05n0 < n < 1.2n0, cylinder actual speed has deviation with setting rotating speed, on operation screen, send alarm, cylinder remains in operation.
When n≤0.8n0 or n >=1.2n0, cylinder actual speed is abnormal, on operation screen, sends alarm, and cylinder shuts down.
