Slot, inside groove are set in outer groove, and the height of inside groove is less than the height of outer groove, and the loop exit of finish circulating tank is recycled by finish
The inside groove of pump connection finishing bathtray, the loop head of the outer groove connection finish circulating tank of finishing bathtray, the inlet side of finishing bathtray and outlet
Side is respectively equipped with compression roller, and inlet side and outlet side are respectively equipped with draw roll one, and draw roll one is set in the outer groove of finishing bathtray
The lower section of compression roller, inlet side and outlet side further respectively have draw roll two, draw roll two and compression roller in the outer groove of finishing bathtray
Pairing setting, the inside groove of finishing bathtray is interior to be equipped with multiple location guides.
Further, heat exchanger uses coil exchanger.
Further, finish delivery pump connection central controller.
Further, finish circulating pump uses diaphragm pump.
Further, location guide is set on by the way of interlocking up and down in the inside groove of finishing bathtray.
The beneficial effects of the invention are as follows：
First, finish of the present invention is directly configured, conveys at the scene, does not need to long-distance sand transport.The finish added is pure finish, can be with
Concentration error caused by when preventing from being artificially configured finish.Finish conveying revolution speed can be adjusted, and teletransmission is to central controller and yield
Interlocking does not need to artificial adjustment, ensures that repairing amount and production ratio are constant.
2nd, this kind of polyacrylonitrile-based carbon fibre oil feeding system has coil exchanger inside finish circulating tank, leads to chilled water
Finish heat exchange is given, ensures that finish temperature maintains lower value, it will not be rotten when temperature is excessively high.Finish delivery pump uses diaphragm
Pump, avoids due to finish demulsifying phenomenon caused by centrifugal pump high speed shear so that finish service life is elongated.
3rd, finish inside active ingredient can be prevented in roller without draw roll one, draw roll two inside finishing bathtray of the present invention
End face is adhered to, and ensures that oil concentration is stablized inside finishing bathtray.Multiple location guides are set inside finishing bathtray, and tow process is squeezed repeatedly
Pressure, fibrillation so that the effect that oils is more uniform.Finishing bathtray inlet and outlet setting compression roller can adjust the water content of import tow,
And the oil content of tow is exported, control the oil applying rate of tow.Finishing bathtray can make the outstanding of surface by the way of the overflow of both sides
The timely overflow of float is gone out, and avoids sticking on tow, brings rear road program into, influences rear road scene operation and finished product carbon fiber
Physicochemical property.
