detailed description:

An optical fiber automatic cutting and winding device for loose tube production, which includes the following components: winding wheel 2, cutting and pressing block 1, hollow shaft 6, self-resetting cylinder 3, servo motor 10 and bracket 15, hollow shaft 6 is fixed on the top of the bracket 15 through two bearing seats 7, the winding wheel 2 is fixed on the right end of the hollow shaft 6, and the synchronous wheel 8 is fixed on the left end of the hollow shaft, and the servo motor 10 is connected with the synchronous wheel 8 through the synchronous belt 9 , that is, the servo motor 10 drives the hollow shaft 6 to rotate. In the winding wheel 2, take the radius of the winding wheel as the center line to provide an installation base groove 19, and a slide rail 5 is installed in the installation base groove 19, and the cutting block 1 is fixed by the slide block 4 and the slide rail 5, automatically The piston rod of the reset cylinder 3 is fixedly connected with the cut-off compaction block 1, and the cut-off compaction block 1 can move up and down on the slide rail 5 under the action of the self-reset cylinder 3, and the left end of the hollow shaft 6 is connected with a rotary joint 11, A solenoid valve 12 for controlling the entry of compressed air is connected to the rotary joint 11. The shaft hole inside the hollow shaft 6 communicates with the self-resetting cylinder 3. The solenoid valve 12, the rotary joint 11 and the shaft hole inside the hollow shaft 6 form a supply Passage through which compressed air passes.

An induction rod 16 is arranged on the winding wheel 2 , and an origin proximity switch 13 opposite to the induction rod 16 is arranged on the bracket 15 .

When in use, the device of the present invention is installed between the optical fiber SZ stranding and the extruder head (not shown in the figure). When the loose tube is produced to the set length or the fiber rack breaks the alarm, the solenoid valve 12 starts, the compressed air reaches the self-resetting cylinder 3 through the pipeline, and the cutting and pressing block 1 installed on the slider 4 is pulled by the slide rail 5. The guide moves downward, cuts the fiber and compresses the fiber tip. At this time, the servo motor 10 drives the winding wheel 2 to rotate and wind the optical fiber in synchronous production speed instantly and start to decelerate. Then through the pulse count of the servo motor encoder and the origin proximity switch 13, the winding wheel 2 is reversed to return to the original position to release the optical fiber, and finally the air source is turned off, the pressing block is cut off, and the optical fiber head is released under the action of the self-resetting cylinder 3, At this moment, the pay-off motor stops. This not only avoids the waste caused by throwing out the remaining loose rings of optical fibers on the tray, but also ensures the stability of the equipment.
