Embodiment Construction

[0016] as attached figure 1 As shown, an optical fiber preform automatic cooling and automatic shear cone device includes an automatic shear head device 4, a signal transmitter 1, a signal receiver 3, and a programmable controller PLC 5 for a drawing furnace. The automatic cutting head device 4 is installed on both sides of the fiber channel under the annealing tube 8 of the fiber drawing furnace, and the signal transmitter 1 and the signal receiver 3 are respectively installed on both sides of the fiber channel under the automatic cutting head device. The programmable controller PLC 5 is respectively connected to the power supply of the automatic cutting head device 4 and the wire drawing furnace 7 through control lines, and the programmable controller PLC 5 is connected to the signal receiver 3 through a signal transmission line. After the signal receiver 3 detects the falling of the material head, the signal receiver 3 feeds back a signal to the programmable controller PLC5...

Abstract

The invention discloses an automatic cooling and automatic cone shearing device for turned optical fiber preformed bars. The device comprises automatic stub bar shearing devices, a signal transmitter, a signal receiver and a programmable logic controller (PLC); the automatic stub bar shearing devices are arranged on two sides of an optical fiber channel below an annealing pipe of an optical fiber drawing furnace, and the signal transmitter and the signal receiver are respectively arranged on the two sides of the optical fiber channel below the automatic stub bar shearing devices; and the automatic stub bar shearing devices comprise two shearing knifes, wherein the two shearing knifes are used for controlling cylinders and respectively arranged on the two sides of the optical fiber channel below the optical fiber drawing furnace, each shearing knife is provided with a shearing knife control cylinder, and the shearing knife control cylinders are controlled through the PLC. The device can automatically monitor falling of stub bars, realize the functions of automatically shearing the stub bars and automatically cooling the drawing furnace, improve the working efficiency of operators and avoid blockage of the drawing furnace.

Description

technical field [0001] The invention relates to an automatic cooling and automatic cone shearing device for an optical fiber preform rod after turning around. Background technique [0002] At present, in the preform drawing equipment of most optical fiber manufacturers, since there is no automatic monitoring device when the fiber preform starts to be drawn and the material head falls, the automatic cutting head and the automatic cooling function of the drawing furnace cannot be realized. After that, you must stay on site for a long period of time, waiting for the whereabouts of the material head, and you cannot leave the site to do some related preparatory work before drawing, which wastes production efficiency. At the same time, because the material head falls quickly, once the operator is negligent and the material cutting head is not timely, it is easy to cause the lower opening of the drawing furnace to be blocked by molten quartz glass.
