Description

Technical Field

[0001] This utility model relates to the field of optical fiber production technology, and in particular to an extrusion device for optical fiber production. Background Technology

[0002] The process of making optical fiber from raw materials such as silicon tetrachloride is crucial for ensuring the quality of optical fiber. The manufacturing process determines the mechanical strength, transmission characteristics and service life of the optical fiber. The manufacturing of communication optical fiber consists of two processes: rod making and fiber drawing. During the production process, the optical fiber needs to be coated with adhesive. However, in the current technology, the adhesive cannot be mixed evenly during the extrusion process, resulting in poor performance.

[0003] Existing patent CN217989870U describes an extrusion device for an optical fiber production line, comprising a support frame. The support frame has a control mechanism and a closing mechanism on its surface. The control mechanism includes a liquid storage tube and a lead screw. A threaded block is threadedly connected to the surface of the lead screw. A fixing groove is formed on the surface of the threaded block. A piston is rotatably connected to the surface of the fixing groove via a bearing. An installation groove is formed on the surface of the piston. A sliding rod is slidably connected to the surface of the installation groove. A locking groove is formed on the surface of the sliding rod. A stirring rod is rotatably connected to the surface of the locking groove via a rotating shaft. A torsion spring is fixedly connected between the stirring rod and the locking groove. A limit groove is formed on the surface of the lead screw. Through the function of the control mechanism, the entire device can achieve uniform mixing of the adhesive during extrusion, resulting in better performance.

[0004] Different fiber optic models have different sizes, which in turn leads to different areas requiring adhesive coating. When spraying different sizes of fiber optics, existing equipment requires the original nozzle to be removed and replaced with a different size nozzle. The disassembly and installation process is cumbersome and inconvenient to store, resulting in low practicality. Utility Model Content

[0021] This utility model provides an extrusion device for optical fiber production, including a body 100, an extrusion device 101, an extrusion tube 102, and a replacement assembly. The replacement assembly includes a mounting frame 103, a rotating shaft 104, a limiting component, a rotating disk 105, a connecting cylinder 106, an extrusion head 107, a positioning block 112, an elastic element, and an abutment block 113. The limiting component includes a sliding ring 108, a limiting block 109, and a driving element. The driving element includes a driving block 110 and a first spring 111. The elastic element includes a telescopic rod 114 and a second spring 115. This solution solves the problem that existing equipment requires the original nozzle to be removed and replaced when spraying optical fibers of different sizes. The disassembly and installation process is cumbersome, and it is not convenient to store, resulting in low practicality.

[0022] In this specific embodiment, the extrusion device 101 is mounted on the machine body 100, and the extrusion tube 102 is mounted on the extrusion device 101. Both the extrusion device 101 and the extrusion tube 102 are control mechanisms and liquid outlet pipes described in the existing patent technology CN217989870U, "An Extrusion Equipment for an Optical Fiber Production Line." The extrusion device 101 is mounted on the machine body 100. The entire device, through the extrusion device 101, can achieve uniform mixing of the adhesive during extrusion, resulting in better performance. The adhesive is extruded from the extrusion device 101 through the extrusion tube 102. This solution enables convenient replacement of the extrusion head, thereby improving work efficiency and the practicality of the equipment.

[0023] The mounting bracket 103 is fixedly connected to the extrusion tube 102 and located on the side of the extrusion tube 102 away from the machine body 100. The rotating shaft 104 is slidably connected to the mounting bracket 103 and located on the side of the mounting bracket 103 away from the extrusion tube 102. The limiting member is mounted on the rotating shaft 104 and supports the rotating shaft 104. The rotating disk 105 is fixedly connected to the rotating shaft 104 and located on the side of the rotating shaft 104 away from the mounting bracket 103. The connecting cylinder 106 is fixedly connected to the rotating disk 105 and positioned... The rotating disk 105 is located on the side away from the rotating shaft 104 and connected to the extrusion tube 102. The extrusion head 107 is fixedly connected to the connecting cylinder 106 and located on the side of the connecting cylinder 106 away from the mounting frame 103. The mounting frame 103 is fixedly mounted on the extrusion tube 102, and the extrusion tube 102 supports the mounting frame 103. The rotating shaft 104 is slidably mounted on the mounting frame 103, allowing the rotating shaft 104 to move up and down within the mounting frame 103 and to rotate. The limiting member is mounted on the mounting frame 103. The limiting member fixes the rotating shaft 104 to prevent it from rotating during use. The rotating disk 105 is fixedly mounted on the rotating shaft 104, supporting it and causing it to move up and down and rotate. Multiple connecting cylinders 106 are arranged circumferentially on the rotating disk 105. The outer dimension of each connecting cylinder 106 is equal to the inner dimension of the extrusion tube 102. A sealing ring is installed inside each connecting cylinder 106 to improve sealing. No glue leakage occurs after the extrusion cylinder enters the connecting cylinder 106. There are multiple extrusion heads 107, and the sizes of the multiple extrusion heads 107 are different. The extrusion heads 107 are fixedly installed on the connecting cylinder 106, so that the glue in the extrusion cylinder is transferred to the extrusion head 107 through the connecting cylinder 106, and the extrusion head 107 completes the extrusion. By rotating the rotating disk 105, different connecting cylinders 106 are connected to the extrusion tube 102, thereby realizing convenient replacement of extrusion heads, improving work efficiency and the practicality of the equipment.

[0024] Secondly, the sliding ring 108 is fixedly connected to the rotating shaft 104 and located on the side of the rotating shaft 104 near the mounting bracket 103, and is connected to the mounting bracket 103. The limiting block 109 is slidably connected to the mounting bracket 103 and located on the side of the mounting bracket 103 away from the extrusion tube 102, and abuts against the sliding ring 108. The driving element is mounted on the limiting block 109, and the driving element drives the limiting block 109 to move. The sliding ring 108 is fixedly mounted on the rotating shaft 104, and the outer side of the sliding ring 108 abuts against the mounting bracket 103. Mounting bracket 103 has a groove that mates with the sliding ring 108, allowing the sliding ring 108 to move stably within the mounting bracket 103, thereby limiting the height of the rotating shaft 104. The limiting block 109 is slidably mounted on the mounting bracket 103, and the driving element is mounted on the limiting block 109. The driving element drives the limiting block 109 to move, causing the limiting block 109 to engage the sliding ring 108, positioning the sliding ring 108 above the groove in the mounting bracket 103. This, in turn, keeps the rotating disk 105 at a specified height, ensuring a stable connection between the connecting cylinder 106 and the extrusion cylinder.

[0025] Meanwhile, the driving block 110 is fixedly connected to the limiting block 109 and is located on the side of the limiting block 109 away from the mounting bracket 103; the first spring 111 is sleeved on the outside of the driving block 110, and the two ends of the first spring 111 are respectively connected to the driving block 110 and the mounting bracket 103. The driving block 110 is fixedly installed on the end of the limiting block 109 away from the mounting bracket 103. The driving block 110 drives the limiting block 109 to move. The first spring 111 is sleeved on the outside of the limiting block 109, and the two ends of the first spring 111 are respectively fixed on the driving block 110 and the mounting bracket 103. The first spring 111 pulls the driving block 110 to move, so that the limiting block 109 locks the sliding ring 108, thereby fixing the rotating shaft 104.

[0026] Additionally, the positioning block 112 is fixedly connected to the rotating shaft 104 and located on the side of the rotating shaft 104 away from the rotating disk 105; the abutment block 113 is connected to the mounting bracket 103 through the elastic element, the elastic element supports the abutment block 113, the abutment block 113 abuts against the positioning block 112, and the positioning block 112 is fixedly installed on the rotating shaft 104 by bolts. The positioning block 112 allows the operator to easily drive the rotating shaft 104 upwards. The rotating shaft 104 is moved and rotated. The abutment block 113 is mounted on the mounting bracket 103 through the elastic element. The upper part of the abutment block 113 is arc-shaped. The positioning block 112 has a hole, and the position of the hole is consistent with the position of the connecting cylinder 106. The abutment block 113 is parallel to the center of the extrusion tube 102, so that when the abutment block 113 abuts against the positioning block 112 and generates resistance, the connecting cylinder 106 is just aligned with the extrusion tube 102, which facilitates installation.

[0027] Finally, the telescopic rod 114 is fixedly connected to the mounting bracket 103 and located on the side of the mounting bracket 103 near the positioning block 112, and connected to the abutment block 113; the second spring 115 is sleeved on the outside of the telescopic rod 114, and the two ends of the second spring 115 abut against the mounting bracket 103 and the abutment block 113 respectively. One end of the telescopic rod 114 is fixedly installed on the mounting bracket 103, and the telescopic rod 114 and the extrusion cylinder are on the same straight line. The other end of the telescopic rod 114 is connected to the abutment block 113, so that the abutment block 113 can move up and down. The second spring 115 is sleeved on the outside of the telescopic rod 114, and the two ends of the second spring 115 abut against the mounting bracket 103 and the abutment block 113 respectively, so that the abutment block 113 moves upward, so that the abutment block 113 can abut against the positioning block 112 and generate resistance.

[0028] Using the extrusion device for optical fiber production in this embodiment, when the extrusion head 107 needs to be replaced, the driving block 110 drives the limiting block 109 to move, causing the rotating shaft 104 to drive the rotating disk 105 to move downward. At this time, the connecting cylinder 106 moves downward and separates from the extrusion tube 102. Then, the rotating disk 105 is rotated so that the extrusion head 107 of a specified size is located below the extrusion cylinder, causing the abutment block 113 to abut against the positioning block 112 and generate resistance. At this time, the rotating shaft 104 is moved upward so that the extrusion cylinder extends into the inner wall of the connecting cylinder 106, thereby connecting the connecting cylinder 106 with the extrusion cylinder. At this time, the driving block 110 is released, and the limiting block 109 fixes the sliding ring 108, thereby realizing the replacement of the extrusion head size and improving the practicality of the equipment.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
