Description

Technical Field

[0001] The utility model belongs to the technical field of bundled optical fibers, in particular to a heating device for a melting process. Background Art

[0002] Existing bundled optical fibers are mainly bonded with inorganic or organic glue to encapsulate the optical fiber bundle into the required shape. However, during the use of the bonded bundled optical fiber, the long-term passage of high-power laser light will cause scattering and reflection at the end face. Part of the high-power laser will be reflected back to the glue connection of the optical fiber bundle, causing cracking and debonding problems on the end face of the bundled optical fiber, thereby causing damage.

[0003] To address the above phenomenon, a melting process can be selected to melt the optical fiber bundle and the newly added quartz tube into a whole, which can avoid gluing the bundled optical fiber and thus solve the problem of cracking and debonding.

[0004] As for the heating device in the melting process, the quartz tube and the optical fiber bundle are heated and melted into a whole. However, most of the current oxyhydrogen flame heads are handheld, which makes it difficult to control the stability of the flame. At the same time, for the melting heating of the quartz tube, it is necessary to ensure that the flame head has rotation and translation functions to optimize the uniformity of heating and melting. The existing melting heating device cannot meet the processing requirements of molten bundled optical fibers.

[0005] Therefore, designing a heating device with stronger heating uniformity is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of the utility model is to provide a heating device for the melting process. By designing a new type of heating device, it is possible to achieve highly uniform heating in the melting process of the bundled optical fiber, ensure heating stability, thereby improving the melting effect and improving the quality of subsequent use of the molten bundled optical fiber.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] A plurality of oxyhydrogen flame heads are fixed in an annular shape in the inner cylinder through a cylinder, the oxyhydrogen flame heads face the axis of the annular frame, the air inlet of the oxyhydrogen flame head is connected to a hose, and the other end of the hose passes through the inner cylinder and is connected to the air supply pipe;

[0011] The annular frame is fixed to the top of the sliding seat through a column, the driving mechanism is fixed to the top of the sliding seat and the output end is connected to a gear, the inner cylinder is provided with an arc-shaped tooth plate at one end close to the driving mechanism, and the gear is located below the arc-shaped tooth plate and meshes with the arc-shaped tooth plate;

[0013] Furthermore, an air delivery pipe is fixed to the peripheral side of the air supply pipe, and the air supply pipe is located at a position on the inner cylinder away from the arc-shaped tooth plate.

[0014] Furthermore, the air supply pipe is fixed to the outside of the inner cylinder through a plurality of pipe clamps, and the air delivery pipe and the plurality of pipe clamps are misaligned.

[0015] Furthermore, both ends of the arc-shaped tooth plate are respectively opposite to the two adjacent hydrogen-oxygen flame heads of the inner cylinder, and both ends of the arc-shaped tooth plate are provided with limit stops.

[0016] Furthermore, side plates are provided at both ends of the gear, and a bottom plate is fixed at the bottom between the two side plates.

[0019] The utility model designs a novel heating device, which can achieve high uniformity of heating in the heating of the bundled optical fiber melting process, ensure heating stability, thereby improving the melting effect and improving the use quality of the subsequent fused bundled optical fiber.

[0020] The oxyhydrogen flame head of the utility model can be adjusted to a certain arc angle, and the angle change of the small arc degree can completely cover the entire quartz sleeve. Compared with the 360-degree adjustment, the adjustment of the small arc angle is conducive to control and will not affect the air intake.

[0021] The utility model uses a cylinder for installing an oxyhydrogen flame head, which can adjust the distance between the oxyhydrogen flame head and the quartz tube, thereby adjusting the distance between the heating point and the quartz tube, realizing adjustment of the firepower, thereby realizing appropriate adjustment of the subsequent melting effect, and optimizing the melting process.
