Problems solved by technology

[0005] At present, the rod drawing method is generally carried out by single-row hole drawing. When we need to increase the number of single-drawing holes, the number of inserting rods will increase to both sides, which leads to an excessively large angle between the quartz glass fiber strands on both sides. , not conducive to drawing operations
Restricted by the technological principle that the α angle generally does not exceed 7°, it is difficult to increase the number of drawing holes and the drawing output on the basis of the existing single-row hole drawing

Embodiment 1

[0032] figure 1 It is a structural diagram of the annular wire drawing device of Embodiment 1 of the present invention.

[0033] Such as figure 1 As shown, the annular wire drawing device of Embodiment 1 of the present invention includes a rod lowering mechanism 1 , a rod clamping mechanism 2 , a positioning mechanism 3 , a rod melting device 4 , a clustering mechanism 5 , a wire arranging mechanism 6 and a wire winding mechanism 7 . Wherein, the lower rod mechanism 1 has a lifting structure, which can move the clamping rod structure 2 in the vertical direction. The clamping rod mechanism 2 is connected with the lifting structure, and holds a plurality of quartz glass rods in a vertical state in a circular arrangement.

[0034]The positioning mechanism 3 is located below the rod clamping mechanism 2, and has a plurality of circularly arranged through holes corresponding to the quartz glass rods held by the rod clamping mechanism 2, so that each quartz glass rod passes throug...

Embodiment 2

[0060] The present invention has been described above as a preferred embodiment 1, but various changes can be made in carrying out the present invention, and a second embodiment of the present invention will be described below. For the sake of brevity, the same parts as those in Embodiment 1 will not be repeated.

[0061] In this embodiment, the difference from Embodiment 1 lies in the bundling mechanism. The second-level bundling method is used in Embodiment 1, and the third-level bundling method is used in this embodiment.

[0062] In this embodiment, the first-level converging mechanism includes a plurality of concentrators 52, and each concentrator 52 is configured to be similar to the second concentrator 52 in Embodiment 1, that is, a plurality of converging grooves are arranged on one side surface, and quartz The glass fiber strands are bundled into one group through the bundle groove. A plurality of bundlers 52 are evenly distributed in the circumferential direction, so...

Abstract

The invention provides an annular wire drawing device, and relates to the field of quartz glass fiber precursor manufacturing, and the annular wire drawing device comprises a rod feeding mechanism, a rod clamping mechanism, a positioning mechanism, a rod melting device, a bundling mechanism, a wire arranging mechanism and a wire winding mechanism. The rod discharging mechanism comprises a lifting structure; the rod clamping mechanism is used for holding a plurality of quartz glass rods in an annular arrangement mode in a vertical state; the positioning mechanism is positioned below the rod clamping mechanism and is provided with a plurality of through holes which are annularly arranged corresponding to the quartz glass rods held by the rod clamping mechanism; the rod melting device is located below the positioning mechanism and melts the quartz glass rod penetrating through the positioning mechanism to generate a quartz glass fiber precursor; the wire arranging mechanism is located below the bundling mechanism. The wire winding mechanism is located below the wire arranging mechanism and used for winding the arranged quartz glass fiber precursors. According to the scheme, by changing the arrangement mode of the holes, the number of wire drawing holes and the yield are increased, and the consistency of raw wires is enhanced. The invention also provides a quartz glass rod wire drawing method.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the field of producing quartz glass fiber precursors, and more particularly, relate to an annular drawing device and a method for drawing quartz glass rods. Background technique [0002] There are currently three production methods for continuous production of quartz glass fibers: rod drawing method, melt drawing method and sol-gel method. Based on the consideration of practicality and economic cost, the rod drawing method is used to produce quartz glass fiber in industry. The rod drawing method is to heat and melt quartz glass rods with a diameter of about 1.8 to 4 mm, draw the wires from the melting place, and integrate them into a bundle, then apply the sizing agent through the bundle wheel, and pull it by a high-speed rotating wire drawing machine, and then continuously pass it by the wire arranging wheel. Wound on the bobbin to become a continuous quartz glass fiber precursor. [0003] In...
