Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber production equipment, in particular to an optical fiber invalid drawing collection tube. Background Art

[0002] For optical fiber preform, we can call it effective drawing area and invalid drawing area. Due to the production and manufacturing process of optical fiber preform, the invalid drawing area usually refers to part of the tip and tail of the preform.

[0003] Before a new rod is normally drawn, we need to cut the invalid drawing area of ​​the rod tip into a cone and scrap it (mainly the part without core layer). The required cone weight is about 4KG (based on the actual node position of the core layer). Due to the inconsistency of the cone size and diameter of the tip of the optical rod, in order to cut the invalid area cleanly, this process takes more than 15 minutes. The conventional operation method is to place an optical fiber head-turning barrel at a certain distance from the lower mouth of the drawing furnace, and use pliers to pull the optical fiber cone until the invalid drawing area of ​​the optical rod is cut cleanly before continuing to the next step.

[0004] The common U-turn barrel in the prior art has many inconveniences:

[0005] 1) The height of the barrel is not enough, which increases the frequency of cone cutting. The fiber falls quickly and easily touches the bottom directly, causing the fiber to bend and increase the risk of furnace blockage.

[0006] 2) Broken optical fiber is easy to splash outside the tube, and high-temperature glass slag is easy to cause burns to personnel and pollute the environment of the drawing channel

[0007] 3) When too much tapered optical fiber in the barrel protrudes out of the barrel mouth, it is necessary to use an iron rod to knock the optical fiber off. This process is troublesome to operate, distracting the personnel's attention from cutting the cone, and easily causing the risk of furnace blockage. When knocking the optical fiber, a large amount of broken fiber splashes everywhere, increasing the difficulty of subsequent sanitation and cleaning. Utility Model Content
