Description

Technical Field

[0001] This utility model belongs to the field of tapered optical fiber production technology, and in particular relates to a marking device for tapered optical fiber drawing towers. Background Technology

[0002] Tapered optical fibers have different diameters, controlled by a narrow-thickness-narrow-thickness pattern. The connecting section has a tapered structure. After coating, the overall fiber diameter remains consistent due to the setting of the coating layer. Now, tiny marks can be etched on the coating layer by marking, which is highly accurate and does not damage the optical fiber. By marking the points where the fiber diameter changes, the location of the change points can be directly determined by appearance, which is convenient for subsequent installation and debugging.

[0003] Currently, laser marking is mostly used to mark optical fibers after drawing, coating, and curing in the fiber drawing tower. However, due to the high fiber drawing speed, and the influence of temperature fluctuations and surface tension in the preform melting zone, mechanical vibration, airflow disturbances, and fiber tension fluctuations, the optical fiber may experience certain lateral swaying problems, which will affect the marking accuracy and the marking position on the optical fiber. Summary of the Invention

[0004] The purpose of this invention is to provide a marking device for tapered fiber drawing towers. The fiber is clamped by a whole capsule and two sub-capsules, which can be clamped using a three-point support method. The tightening force can be transmitted with the fiber, ensuring the positional stability of the fiber during marking and improving the marking quality. The marking can be marked on the fiber by a laser nozzle, and the marking points indicate the fiber diameter change points, which can determine the position of the tapered section on the tapered fiber.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a marking device for a tapered fiber drawing tower, comprising a first clamping component, a second clamping component, and a laser nozzle; Both the first clamping member and the second clamping member include a pusher frame.

A whole belt body is driven between the two pulleys of the first clamping member, and a whole bag body is fixed on the circumferential side of the whole belt body; The two sides of the two pulleys of the second clamping member are connected to the belt body for transmission. The belt body has a segmented capsule fixed to its peripheral side. Both the whole capsule and the segmented capsule are filled with gas. A clearance gap is formed between the two segmented capsules. The outer sides of the two segmented capsules are flush with the two sides of the whole capsule, respectively. The laser nozzle is fixed on the pusher of the second clamping component by the frame, and the laser nozzle faces the clearance interval.

[0006] Furthermore, the pusher includes a set of side plates, with the two pulleys respectively disposed at the top and bottom ends between the two side plates, and a connecting seat fixed on the outer side between the two side plates, and the end of the telescopic rod of the adjusting cylinder is fixed to the connecting seat.

[0007] Furthermore, the frame includes a horizontal plate, which is fixed to the top surface of the connecting seat of the second clamping member. A vertical plate is fixed to the top of the horizontal plate. The laser nozzle is slidably mounted on the top surface of the horizontal plate via a slide block. An adjustment mechanism is provided between the slide block and the vertical plate.

[0008] Furthermore, the adjustment mechanism includes a screw that passes through the vertical plate and is threadedly connected to the vertical plate. One end of the screw is rotatably connected to the outer side of the slide block, and the other end of the screw is provided with a throttle handle.

[0009] Furthermore, a mounting base is fixed on the adjusting cylinder, and the mounting base is an L-shaped base plate.

[0010] Furthermore, the pulley of the second clamping member has an outward protrusion in the middle, and the sides of the belt splitter and the bag splitter contact the outward protrusion.
