[0034] Referring to Figure 4The clamping rod mechanism 8 comprises a sliding block 801 which is slidingly connected to the top of the slide rail 7. The sliding block 801 is slidingly connected to the slide rail 7 in such a way that the clamping rod mechanism 8 can move smoothly along the path defined by the slide rail 7, thereby providing stable guidance for the conveying of the quartz rod 10. The top of the sliding block 801 is fixedly connected to a screw block 802.

[0036] Referring to Figure 3 , the quartz filament pulling mechanism 15 includes two fixed plates, between which two rollers are rotatably connected. The two rollers can exert a stable pulling force on the softened quartz rod 10 through rotation, uniformly drawing it into fine quartz filaments 14.

[0037] Referring to Figure 1 , the flame blowing mechanism 16 includes a mounting plate, on which a plurality of flame injectors are fixedly connected. The plurality of flame injectors are installed on the mounting plate and can simultaneously blow on the fine quartz filaments 14, uniformly blowing the fine quartz filaments 14 into quartz fiber cotton.

[0038] Referring to Figure 2 and Figure 3 , a plurality of lead screw seats 5 are fixedly connected to the top of the rack 1, and the outer wall of the lead screw 6 is rotatably connected to the inside of the lead screw seat 5. The lead screw seat 5 provides stable support and rotation basis for the lead screw 6, enabling it to remain stable during rotation.

[0041] Referring to Figure 1 The laser diameter measuring module 13 comprises the same number of measuring assemblies as the quartz rods 10. Each measuring assembly is in mutual feedback with the corresponding servo motor 2 through the central control system. The laser diameter measuring module 13 is used for detecting the diameter of the fine quartz filaments 14. When the laser diameter measuring module 13 detects that the diameter of the fine quartz filaments 14 changes, the change information can be quickly transmitted to the central control system. The central control system adjusts the rotating speed of the corresponding servo motor 2 in time according to the information, so as to adjust the feeding speed of the quartz rod 10 and correct the diameter of the fine quartz filaments 14, thereby ensuring that the single-filament diameter of the produced quartz fiber cotton is uniform.

[0042] Working principle: The quartz rod 10 is sequentially inserted through the quartz rod positioning hole 903 on the quartz rod positioning sliding block 901, and then the end of the quartz rod 10 is placed into the quartz rod positioning groove 805 on the lead screw sliding block 802.

The primary burner 12 is ignited, the servo motor 2 is started, and the quartz rod 10 slowly advances. When the front end of the quartz rod 10 passes through the primary burner 12, the worker pulls the softened quartz rod 10 into the quartz filament drawing mechanism 15. The quartz filament drawing mechanism 15 draws the quartz rod 10 into fine quartz filaments 14. When the fine quartz filaments 14 pass through the flame blowing mechanism 16, the flame blowing mechanism 16 is ignited to blow the fine quartz filaments 14 into quartz fiber cotton.

[0043] When the rod clamping mechanism 8 passes through the quartz rod stabilizing mechanism 9, the quartz rod positioning sliding block separation structure 804 will first contact the quartz rod positioning sliding block separation structure guide groove 902. When the rod clamping mechanism 8 continues to move forward, the quartz rod positioning sliding block 901 in the quartz rod stabilizing mechanism 9 will be separated by the quartz rod positioning sliding block separation structure 804, so that the rod clamping mechanism 8 can pass through, thereby ensuring that the quartz rod 10 remains stable during the advancing process.

[0044] When the quartz fiber pulling mechanism 15 is pulling the fine quartz fiber 14, the fine quartz fiber 14 will pass through the laser measuring module 13, the laser measuring module 13 comprises the same number of measuring assemblies as the quartz rod 10, each measuring assembly is feedback with the corresponding servo motor 2 through the central control system, the laser measuring module 13 can measure the diameter of each fine quartz fiber 14 in real time, when the diameter of the fine quartz fiber 14 changes, the laser measuring module 13 can transmit the change information to the central control system, the central control system can timely adjust the rotating speed of the servo motor 2 to correct the diameter of the fine quartz fiber 14. In this way, the diameter of the single filament of the quartz fiber cotton produced can be more uniform, and the product stability is better.

[0045] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
