Existing bus production line comprises pay off rack, batching stirring system, extruder, head, cross-linked pipeline and take-up mechanism, the batching discharging opening of stirring system is connected with the feed bin of extruder, the discharging opening of batching stirring system is provided with meter and heavily claims, the batching heavily being taken approrpiate wts by meter adds in feed bin, but owing to needing to stir batching in batching stirring system, and meter heavily claim calculate be batching gravity, therefore inaccurate situation of weighing can be caused to occur, thus affect the quality of bus.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bus production line for above drawback, can adjust feeding coal in real time, more accurately reliable, ensure that the quality of production of bus.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of bus production line, comprise extruder, described extruder comprises feeder, described feeder comprises feed bin and feeding mechanism, described feed bin is arranged on the top of described feeding mechanism, wherein, the discharging opening of described feed bin is provided with measuring pump, described feeding mechanism comprises feed belt, pressure gauge is provided with between described feed belt, described pressure gauge is fixed on described feeding mechanism by support, described feed belt rotates clockwise, described feeding mechanism is also provided with pressure sensor, described pressure gauge is connected with described pressure sensor, described pressure sensor is connected with terminal control unit CPU, described terminal control unit CPU respectively with feeding mechanism controller, feed bin controller is connected, described feeding mechanism controller controls the velocity of rotation of feed belt, described feed bin controller controls the discharging speed of measuring pump,
Its operation principle for: the batching needed for production enters in measuring pump by feed bin, and by measuring pump discharging on the feed belt of feeding mechanism, pressure gauge below feed belt reads pressure value now, and by pressure sensor by signal transmission to terminal control unit CPU, terminal control unit CPU according to the pressure value received respectively by feeding mechanism controller, the feed bin controller adjustment transfer rate of feed belt and the discharging speed of meter, if the pressure value received is less than rated value, then increase the transfer rate of feed belt and the discharging speed of meter, if the pressure value received is greater than rated value, then reduce the transfer rate of feed belt and the discharging speed of meter, both be combined with each other, to realize the accurate feeding of charging gear.
Beneficial effect of the present invention is:
The pressure value of the batching on feeding mechanism is dropped on by pressure gauge perception, compare and measure gravity numerical value, impact by angle and other factors is less, numerical value is more accurate, and the use of measuring pump further ensure that the accuracy of feed, by cooperatively interacting between pressure sensor and terminal control unit CPU, realize automation feed, feeding coal can be adjusted in real time, more accurately reliable, ensure that the quality of production of bus.
