In the prefabricated stick drawn wire equipment of most optical fiber production producer, due to the automated watch-keeping facility not having in the time that preform starts wire drawing formation stub bar whereabouts, can not realize automatic shearing stub bar and fiber drawing furnace automatic cooling function, operator just must stop at the scene longer for some time after fiber drawing furnace heats up, wait for the whereabouts of stub bar, the front preparation work of some relevant wire drawings, waste production efficiency are done in the scene of can not leaving.Very fast while dropping due to stub bar, once operator's carelessness, cropping not in time, is easy to cause the silica glass that fiber drawing furnace end opening is melted to stop up simultaneously.
Summary of the invention
Goal of the invention is in order to solve the deficiencies in the prior art, after providing a kind of preform to turn around, automatically lower the temperature and automatic shearing wimble device, can automatically monitor stub bar, realize automatic shearing stub bar and the fiber drawing furnace function of cooling automatically, the phenomenon that improves operator's working efficiency and avoid fiber drawing furnace to stop up.
After preform of the present invention turns around, automatic cooling and automatic shearing wimble device are to take following technical scheme to realize: after a kind of preform turns around, automatic cooling and automatic shearing wimble device comprise automatic shearing stub bar device, signal projector, signal receiver and programmable logic controller PLC.
Automatic shearing stub bar device is arranged on the both sides of fibre drawing furnace annealing pipe below optical-fibre channel, and signal projector and signal receiver are arranged on respectively the both sides of automatic shearing stub bar device below optical-fibre channel.
Automatic shearing stub bar device comprises two shear knives, two shear knife control cylinders, two shear knives are arranged on respectively the both sides of fibre drawing furnace below optical-fibre channel, and two shear knives are equipped with respectively shear knife control cylinder, and shear knife control cylinder is controlled by programmable logic controller PLC.
What programmable logic controller PLC adopted is Omron CV2000 controller, is arranged in electrical control cabinet, and controller is connected with magnetic valve by control line.Signal receiver is connected with programmable logic controller PLC by signal transmission line.Signal receiver and signal projector adopt commercially available infrared transmitter and receptor.
Programmable logic controller PLC is connected with fiber drawing furnace heating power supply by control line.Programmable logic controller PLC is connected with signal receiver by signal transmission line.Signal receiver detects under stub bar and falls behind, signal receiver feeds back signal to programmable logic controller PLC, and programmable logic controller PLC controls the control cylinder of automatic shearing stub bar device, makes shear knife produce relative movement, complete cropping operation, stub bar is cut and fallen to stub bar bucket.Programmable logic controller PLC controls the fiber drawing furnace power supply certain power of reduction automatically simultaneously, thereby realizes fiber drawing furnace automatic cooling function.
The automatic shearing stub bar device of the both sides of optical-fibre channel below fibre drawing furnace annealing pipe, a signal projector and a signal receiver, signal receiver is connected to programmable logic controller PLC by data line, carries out signal transmission, realizes automatic shearing stub bar and fiber drawing furnace and automatically lowers the temperature.
As optimization, below fibre drawing furnace annealing pipe, the both sides of optical-fibre channel are provided with a signal projector and a signal receiver, can realize automatic monitoring surveys the stub bar of preform drawing while starting and falls, in the time that stub bar falls between signal projector and signal receiver, signal receiver feeds back to the programmable logic controller PLC of automatic clipping apparatus and fiber drawing furnace.
As optimization, below fibre drawing furnace annealing pipe, the both sides of optical-fibre channel are provided with an automatic shearing stub bar device, in the time of the signal receiving from programmable logic controller PLC, realize automatic shearing stub bar function.
As optimization, signal receiver is connected to programmable logic controller PLC, in the time that programmable logic controller PLC receives the signal feeding back from signal receiver, realizes fiber drawing furnace automatic cooling function.
Beneficial effect of the present invention: the automatic monitoring after the present invention realizes prefabricated rods and turns around, receiving after signal, realize automatic shearing stub bar and the fiber drawing furnace function of cooling automatically, improve operator's working efficiency, reduce human operational error's impact, the phenomenon of avoiding silica glass that fiber drawing furnace end opening is melted to stop up.Use the present invention, make within operator form and fall during this period of time after stub bar to preform from fiber drawing furnace heats up, needn't stay on-the-spot wait, can increase work efficiency.In addition, because fiber drawing furnace annealing pipe caliber is less, after the present invention can realize stub bar and gets off, fiber drawing furnace is lowered the temperature automatically, avoids cropping not in time, causes the silica glass of melting to be deposited in fiber drawing furnace, causes fiber drawing furnace end opening blockage problem.
Brief description of the drawings
