Description

Technical Field

[0001] This utility model belongs to the field of optical fiber preform cold processing technology, and in particular relates to a vertical rod-mounting device for cold processing of optical fiber preforms. Background Technology

[0002] Optical fiber preforms are raw materials used to manufacture optical fibers. They are typically composed of a rod-shaped material with a special structure and chemical composition. The manufacturing process of optical fibers usually involves processing the optical fiber preforms into the final optical fiber.

[0003] According to the published apparatus and method for preparing irregularly shaped optical fiber preforms (Publication No.: CN113043475A), the apparatus includes a base, a control system, a take-up drum, a wire, a movable roller, upper and lower fixed rollers, and a workpiece support. The take-up drum is fixed to the base via a slide rail. The forward and reverse rotation of the take-up drum drives the wire wound on the drum to reciprocate. The tension of the wire is adjusted by adjusting the position of the movable roller. The control system cuts the preform by setting the speed of movement along the slide rail and the mileage of the forward and reverse rotation of the take-up drum. However, the apparatus, with its movable roller, upper and lower fixed rollers, and workpiece support, makes it difficult to simultaneously fix the optical fiber preform body and clean up the waste generated during processing. This makes it difficult to ensure the stability of the optical fiber preform during processing, increases processing errors due to unstable clamping, and makes it difficult to effectively clean up waste during processing. Further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a vertical rod-mounting device for cold processing of optical fiber preforms. The force of the bidirectional reciprocating screw driven by the motor cooperates with the chain wheel, positioning plate and reciprocating screw in the fixing device to realize the displacement of the rotating rod to drive the gear to move, so that the gear meshes with the rack to rotate, and then the rotation of the gear drives the rotating rod to rotate, and the rotation of the rotating rod drives the fan blade to rotate, thus solving the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a vertical rod-mounting device for cold processing of optical fiber preforms, including a protective plate, on the top of which the optical fiber preform body is provided. A fixing device is provided on the top of the protective plate. The fixing device includes a fixing plate, which is fixedly connected to the side of the protective plate. A motor is fixedly connected to the side of the fixing plate. A bidirectional reciprocating screw is fixedly connected to the output shaft of the motor. A threaded block is threadedly connected to the circumferential surface of the bidirectional reciprocating screw. A clamping plate is fixedly connected to the side of the threaded block. A sprocket is fixedly connected to the circumferential surface of the bidirectional reciprocating screw. A chain is provided on the side of the sprocket. A positioning plate is fixedly connected to the side of the protective plate. A reciprocating screw is rotatably connected to the side of the positioning plate. A chain wheel is fixedly connected to the circumferential surface of the reciprocating screw. A threaded sleeve is threadedly connected to the circumferential surface of the reciprocating screw. A mounting plate is fixedly connected to the top of the threaded sleeve. A rotating rod passes through the side of the mounting plate. A gear is fixedly connected to the circumferential surface of the rotating rod. A fan blade is fixedly connected to the circumferential surface of the rotating rod. A rectangular plate is fixedly connected to the side of the protective plate. A rack is fixedly connected to the side of the rectangular plate.

[0006] Furthermore, a limiting rod extends through the side of the threaded block, one end of which is fixedly connected to the side of the fixing plate. A limiting plate is fixedly connected to the bottom of the threaded sleeve, and the end of the limiting plate away from the threaded sleeve is slidably connected to the top of the protective plate. The design of the limiting rod can limit the threaded block, increasing the stability of the device.

[0007] Furthermore, the fixing device includes a cleaning structure, which includes a rotating shaft fixedly connected to one end of a reciprocating lead screw. A sprocket A is fixedly connected to the circumferential surface of the rotating shaft, and a chain A is provided on the side of the sprocket A. A support plate is fixedly connected to the side of the protective plate, and a rotating rod passes through the side of the support plate. A fixing block is fixedly connected to the circumferential surface of the rotating rod, and a chain wheel A is fixedly connected to the circumferential surface of the rotating rod. A storage box is fixedly connected to the side of the support plate, and a flexible hose passes through the side of the storage box. A nozzle passes through the end of the flexible hose away from the storage box.

[0008] Furthermore, the side of the chain meshes with the side of the chain wheel, the side of the chain meshes with the side of the sprocket, and the side of the gear meshes with the side of the rack. The design of the gear and rack allows the fan blades to rotate, effectively cleaning up waste during the processing.

[0009] Furthermore, the side of chain A meshes with the side of sprocket A, and the design of chain A and sprocket A allows for the alternating squeezing and releasing of the hose by the fixed block, which generates a certain negative pressure, thereby attracting and cleaning the dust generated during the processing.

[0010] Furthermore, the number of threaded blocks is set to two, and they are symmetrical to each other along the vertical central axis of the bidirectional reciprocating screw. The design of the threaded blocks can fix and limit the optical fiber preform body by the clamping plate, preventing the position of the optical fiber preform body from shifting during the processing.

[0011] Furthermore, the number of fan blades is set to several, and they are arranged in a circumferential array on the circumferential surface of the rotating rod. The design of the fan blades can keep the processing area clean, reduce the impact of waste chips on processing accuracy, and improve the long-term stable operation capability of the equipment.

[0012] This utility model has the following beneficial effects: 1. This utility model utilizes the force of a motor-driven bidirectional reciprocating screw to rotate in conjunction with components such as the chain wheel, positioning plate, and reciprocating screw in the fixing device. This achieves the effect of displacing the rotating rod to drive the gear to move, causing the gear to mesh with the rack and rotate. The rotation of the gear then drives the rotating rod to rotate, which in turn drives the fan blade to rotate. This achieves the effect of fixing the optical fiber preform body while cleaning up the waste generated during processing, ensuring the stability of the optical fiber preform during processing, reducing processing errors caused by unstable clamping, and effectively cleaning up waste during processing.

[0013] 2. This utility model utilizes the force of a reciprocating screw rotating to drive a rotating shaft, which, in conjunction with the rotating shaft, storage tank, and nozzle components in the fixing device, pumps fluid by alternately squeezing and releasing the hose through continuous compression by the fixing block. As the fixing block rolls, the hose's elasticity causes it to continuously return to its original shape, creating a negative pressure at the storage tank outlet. This causes the water in the storage tank to be sprayed out through the hose and nozzle, effectively cleaning up dust generated during processing, suppressing dust diffusion, and ensuring a clean working environment and the health of workers.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] A specific application of this embodiment is as follows: The application uses a motor 202 to drive a bidirectional reciprocating screw 203 to rotate. The rotation of the bidirectional reciprocating screw 203 then drives two threaded blocks 204 to move towards each other. The threaded blocks 204 are limited by limiting rods 205 on their sides. The displacement of the threaded blocks 204 then drives the clamping plate 206 to move, thus achieving the function of fixing and clamping the optical fiber preform body 102. The rotation of the bidirectional reciprocating screw 203 drives the sprocket 207 to rotate, and the rotation of the sprocket 207 then drives the chain... Chain 208 rotates, driving chain wheel 209 to rotate, which in turn drives reciprocating screw 211 to rotate. The reciprocating screw 211 then displaces threaded sleeve 212, which is then limited by a limiting plate 213 at its bottom. This displacement of threaded sleeve 212 further displaces mounting plate 214, which in turn displaces rotating rod 215. The displacement of rotating rod 215 then displaces gear 216, causing the gear to... Gear 216 meshes with rack 218 to rotate, which in turn drives rotating rod 215 to rotate. Rotating rod 215 then drives fan blade 217 to rotate, thus cleaning up waste generated during processing. Reciprocating screw 211 rotates, driving rotating shaft 226 to rotate, which in turn drives sprocket A227 to rotate. Sprocket A227 then drives chain A228 to rotate, which in turn drives chain wheel A229 to rotate. The rotation of the chain wheel A229 drives the rotating rod 223 to rotate, which in turn drives the fixed block 224 to rotate. The fixed block 224 continuously squeezes the hose 222, which alternately squeezes and releases the hose to pump fluid. As the fixed block 224 rolls, the elasticity of the hose 222 causes it to continuously return to its original shape, creating a negative pressure at the outlet of the storage tank 221. This causes the water in the storage tank 221 to be sprayed out through the hose 222 and the nozzle 225, thus cleaning the dust generated during the processing.
