Description

Technical Field

[0001] The utility model relates to the technical field of quartz fiber production, in particular to a rod positioning structure for quartz fiber production. Background Art

[0002] Quartz fiber is a high-performance inorganic fiber material made of high-purity silicon dioxide and natural quartz crystals. It has good light transmittance, heat resistance and insulation, and is widely used in optics, electronics, chemicals and other fields. At present, the rod drawing method is often used in industry to produce quartz fiber. The steps of the rod drawing method are as follows: prepare a number of quartz rods of about φ5mm, fix their upper ends on the feeding mechanism through the rod positioning structure, gradually lower them to the heating equipment through the feeding mechanism to melt, and draw wires from the molten place, integrate them into a bundle, apply the impregnation agent through the bunching wheel, and be pulled by the high-speed rotating wire drawing machine. The wire is continuously wound on the winding drum by the wire arrangement wheel to become a continuous quartz fiber.

[0003] In the prior art, rod positioning mostly adopts a opposed clamping structure, which has a poor positioning effect. The quartz rod is prone to shaking and deviating during feeding, affecting the wire drawing quality. In addition, the holes opened on it are fixed and can only install a corresponding number of quartz rods. When the processing technology needs to be changed and the number of quartz rods needs to be adjusted, the entire quartz rod needs to be replaced, which reduces production efficiency.

[0029] Please refer to Figure 1-4 , a rod positioning structure for quartz fiber production, comprising a quartz rod 1, a positioning plate group 2 for fixing the quartz rod 1, and a mounting hanger 3 for connecting the positioning plate group 2 with a feeding mechanism;

[0030] The positioning plate group 2 includes a corresponding fixed plate 4 and a movable plate 5, wherein the movable plate 5 is arranged parallel to the fixed plate 4 and can move up and down relative to the fixed plate 4;

[0031] The upper surface of the fixing plate 4 is provided with a pressure-bearing surface, and a plurality of first positioning holes 6 corresponding to the outer diameter of the quartz rod 1 are provided on the pressure-bearing surface. The first positioning holes 6 are used for the quartz rod 1 to penetrate and radially limit the quartz rod 1.

[0032] The lower surface of the movable plate 5 is provided with a pressure surface, and a plurality of second positioning holes corresponding to the first positioning holes 6 are provided on the pressure surface. When the movable plate 5 moves downwardly close to the fixed plate 4, the second positioning holes can cooperate with the quartz rod 1 in the first positioning holes 6 to further limit the radial position of the quartz rod 1.

[0033] A section of the quartz rod 1 near the end is set as a positioning section, and the positioning section is set between the fixed plate 4 and the movable plate 5. A convex ring 8 is coaxially fixed on the positioning section, and the outer diameter of the convex ring 8 is larger than the outer diameter of the quartz rod 1. When the movable plate 5 moves downward toward the fixed plate 4, the pressure-bearing surface and the pressure-applying surface can be clamped at both ends of the convex ring 8 to axially limit the quartz rod 1. In this embodiment, the convex ring and the quartz rod are fixedly connected in an integrated manner.

[0034] In the above structure, the structures of the fixed plate 4 and the movable plate 5 can be of any shape. In order to achieve the purpose of flexible disassembly, the positioning plate group 2 includes at least two pairs of fixed plates 4 and movable plates 5. The fixed plates 4 and movable plates 5 are both rectangular plates with the same structure. Connectors are provided on the two long sides of the fixed plates 4 and the movable plates 5. The fixed plates 4 can be spliced ​​into an integrated fixed plate along the width direction through the connecting parts, and the movable plates 5 can be spliced ​​into an integrated movable plate along the width direction through the connecting parts.

[0035] Usually, in the production process of quartz fiber yarn, 30 to 60 quartz rods need to be cut at a time. Therefore, in order to take into account the capacity of the quartz rods and the flexibility of assembly, the first positioning holes 6 are provided with at least two rows, and each row has a number of holes evenly distributed along the length direction of the fixed plate 4; in this embodiment, the first positioning holes 6 are provided with two rows, and each row has 15 holes.

[0036] When the fixed plate 4 is assembled into an integrated fixed whole plate, the distance between each row of first positioning holes 6 is equal; correspondingly, when the movable plate 5 is assembled into an integrated movable whole plate, the distance between each row of second positioning holes is equal.

[0037] In the above structure, the connecting member is a strip slider 9 or a strip slide groove 10. In this embodiment, there are three fixed plates 4, one of which (referred to as fixed plate a) has a strip slider 9 as the connecting member, and the other two fixed plates (referred to as fixed plates b) have strip slide grooves 10 as the connecting members. The strip slider 9 on the fixed plate a can be inserted into the strip slide groove 10 on the fixed plate b along the length direction, thereby achieving preliminary splicing.

[0038] In order to ensure the stability of the fixed plates after assembly and increase their connection strength, stop grooves 11 are provided on the two wide sides of each fixed plate 4, and the positioning plate set 2 includes stop blocks 12 that match the stop grooves 11. When the fixed plates 4 are assembled into an integrated fixed plate, the stop blocks 12 can be inserted into each stop groove 11 on the same side of the fixed plate to prevent relative movement between the fixed plates 4 along the length direction. Figure 3 As shown, in this embodiment, two stop blocks are provided, which respectively stop and limit the fixing plate 4 from the left and right sides, thereby effectively preventing the fixing plate 4 from relative movement after being assembled.

[0039] In this embodiment, the structure of the movable plate 5 is the same as that of the fixed plate 4, and will not be described in detail herein.

[0040] A distance adjusting assembly is provided between the fixed plate 4 and the movable plate 5, and the movable plate 5 moves up and down relative to the fixed plate 4 through the distance adjusting assembly; the distance adjusting assembly can be a common structure in the prior art, such as a ball screw, a lifting cylinder, etc.

[0041] Due to the harsh working environment during bar processing, in order to ensure that the positioning plate group 2 has sufficient stability and heat resistance while taking into account the cost of use, the distance adjustment component is an adjusting bolt 13 and an adjusting nut 14 sleeved on the adjusting bolt 13; first mounting holes 15 are symmetrically provided on the left and right sides of the pressure-bearing surface of the fixed plate 4, and second mounting holes are symmetrically provided on the left and right sides of the pressure-exerting surface of the movable plate 5. The first mounting hole 15 is correspondingly arranged to the second mounting hole, and the adjusting screw is vertically arranged between the fixed plate 4 and the movable plate 5, and the two ends of the adjusting screw extend into the first mounting hole 15 and the second mounting hole respectively.

[0042] In the above structure, the first positioning hole 6 is arranged between the two first mounting holes 15, and the second positioning hole is arranged between the two second mounting holes. In this way, the layout can be optimized to prevent the adjusting bolt 13 from interfering with the quartz rod 1.

[0043] A plurality of first positioning posts 17 corresponding to the first positioning holes 6 are downwardly arranged on the lower surface of the fixed plate 4, and a plurality of second positioning posts 18 corresponding to the second positioning holes are upwardly arranged on the upper surface of the movable plate 5, and through holes corresponding to the outer diameter of the quartz rod 1 are coaxially arranged in the first positioning posts 17 and the second positioning posts 18. In this way, the first positioning posts 17 and the second positioning posts 18 can further limit the radial position of the quartz rod 1, thereby improving its stability during processing.

[0044] Working principle: When in use, first, according to the use requirements, the fixed plate 4 and the movable plate 5 are assembled into an integrated fixed plate and a movable plate, and further fixed by the stop block 12, and then the adjusting bolt 13 is installed on the fixed plate through the first mounting hole 15, and the quartz rod 1 to be melted is inserted into the first positioning hole 6, and then the movable plate is placed above the fixed plate to ensure that the adjusting bolt 13 is aligned with the second mounting hole and the quartz rod 1 is aligned with the second positioning hole, and then the movable plate is pressed down to press it against the convex ring 8 of the quartz rod 1, and the adjusting nut 14 is tightened to fix the movable plate, thereby achieving complete radial and axial positioning of the quartz rod 1, and finally the fixed positioning plate group 2 is connected to the unloading mechanism through the mounting bracket 3 to prepare for subsequent rod processing operations.

[0045] The utility model realizes radial and axial dual positioning by cooperating the positioning plate group 2 with the convex ring 8 on the quartz rod 1, effectively preventing the quartz rod 1 from shaking and deviation during the feeding process, and improving the wire drawing quality; through the design of the connecting parts, the fixed plate 4 and the movable plate 5 can be flexibly assembled and disassembled, and can adapt to different process requirements without the need for overall replacement, which greatly enhances the flexibility of use and improves the overall production efficiency of quartz fiber yarn.

[0046] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
