Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber preform manufacturing, and particularly relates to a blowing device for assembling an optical fiber preform. Background Art

[0002] During the assembly process of an optical fiber preform, a blowing device is a key technology used to ensure the cleanliness inside the preform and the quality of the optical fiber. This technology is used to precisely control the air flow rate and pressure injected into the preform by the blowing device. By using an intelligent control system and sensors, the air flow pressure and the situation inside the preform can be monitored in real time to ensure the consistency and stability during the optical fiber manufacturing process. To ensure that the air flow blown into the preform is clean, multi-stage filtering technologies are usually adopted, including coarse filters and fine filters, etc., to remove particles, dust, and impurities in the air. To provide sufficient air flow pressure and flow rate, high-performance air source technologies are usually adopted, such as high-performance compressed air systems or gas booster pumps, etc., to ensure that the blowing device can meet the requirements during the optical fiber manufacturing process.

[0003] According to a blowing device for assembling an optical fiber preform (Publication No.: CN216972342U), it includes a base and a cap fixedly arranged on the base; a through hole one for the optical fiber preform to pass through is provided at the center of the base; a through hole two corresponding to the through hole one provided at the center of the base is provided at the center of the cap; a blowing channel is formed between the cap and the base, and the blowing channel is inclined. The top end of the blowing channel is communicated with the through hole one and the through hole two, and the bottom end of the blowing channel is communicated with an air inlet. However, in the above design, when blowing air into the optical fiber preform, it is not fixed and limited, which easily causes the optical fiber preform to displace, resulting in failure to meet the standards, and improvement is needed.

A chute 611 is opened on the front side surface of the fixed frame 62. A sliding block 63 is slidably connected to the inner side wall of the chute 611. A connecting plate 64 is fixedly connected to the front side surface of the sliding block 63. A return spring 68 is fixedly connected to the top of the sliding block 63, and the end of the return spring 68 far from the sliding block 63 is fixedly connected to the inner side wall of the chute 611.

[0027] A spring telescopic rod 69 is fixedly connected to the inner side wall of the fixed frame 62. A contact plate 610 is fixedly connected to the end of the spring telescopic rod 69 far from the fixed frame 62. A support leg frame 5 is fixedly connected to the bottom of the operating table 1. The design of the contact plate 610 is beneficial. When the contact plate 610 moves, it squeezes the connecting plate 64, so that the connecting plate 64 moves upward.

[0028] The contact plate 610 is slidably connected to the bottom of the connecting plate 64. The side cross-section of the fixed frame 62 is concave. The clamping block 67 is in contact with the circumferential surface of the fixed ring 8. The connecting plate 64 is fixedly connected to the side surface of the sliding plate 65.

[0029] A filter device 7 is arranged inside the air outlet pipe of the air blower 2. The filter device 7 includes a filter net 71. The design of the filter net 71 is beneficial to filtering impurities in the gas and preventing the impurities from entering the interior of the material.

[0030] A fixing plate 72 is fixedly connected to the bottom of the sliding plate 65. A rectangular plate 73 is fixedly connected to the rear side surface of the fixing plate 72. A scraping plate 74 is fixedly connected to the rear side surface of the rectangular plate 73.

[0033] A specific application of this embodiment is as follows: When it is necessary to blow air on the material first, the staff member pulls the contact plate 610 fixed to one end of the spring telescopic rod 69, so that the spring telescopic rod 69 contracts, driving the contact plate 610 to slide at the bottom of the connecting plate 64. When the connecting plate 64 is subjected to the extrusion force of the contact plate 610, it drives the sliding block 63 sliding on the inner side wall of the sliding groove 611 to slide, squeezing the reset spring 68 fixed to the top of the sliding block 63 into a tight state, so that the sliding block 63 drives the connecting plate 64 to move, and at the same time drives the sliding plate 65 fixed to the side of the connecting plate 64 to slide on the inner side wall of the hollow block 61. When the sliding plate 65 slides, it drives the connecting rod 66 fixed to the bottom to move, so as to drive the clamping block 67 fixed to one end of the connecting rod 66. Subsequently, the staff member sleeves the material on the circumferential surface of the fixing ring 8. At the same time, the staff member no longer pulls the contact plate 610. At the same time, the spring telescopic rod 69 drives the contact plate 610 to reset. At the same time, the reset spring 68 is no longer subjected to the extrusion force, so that the sliding block 63 resets, and at the same time the clamping block 67 clamps the outer surface of the material. Finally, when the sliding plate 65 moves, it drives the fixing plate 72 fixed to the bottom to move, and at the same time drives the rectangular plate 73 fixed to the rear side surface to move, so that the scraping plate 74 scrapes the impurities accumulated on the outer surface of the filter net 71.
