Description

Technical Field

[0001] This utility model belongs to the field of optical cable filler rope technology, specifically an optical cable filler rope extrusion structure with temperature control function. Background Technology

[0002] Optical cable filler rope refers to a rope-like material formed by filling the space between the optical cable core and the longitudinal direction of the optical fiber with some elastic materials. Common materials include polystyrene foam, polyurethane foam, polypropylene fiber, glass fiber, high-strength polyester fiber, high-strength polyamide fiber, etc. Filler rope plays a crucial role in optical cables.

[0003] The production process of optical fiber filler rope usually includes multiple steps such as raw material preparation, extrusion molding, cooling and shaping, and traction winding. Extrusion molding involves adding the material into the extrusion cylinder, heating and melting the material inside the extrusion cylinder, and then extruding it from the die.

[0004] In existing optical cable filler rope extrusion structures, uneven heating of the material during extrusion results in poor extrusion performance. Furthermore, the material's agitation within the extrusion tube is minimal, leading to insufficient mixing and uneven extrusion, which in turn affects product quality.

[0005] Therefore, this utility model provides an optical cable filling rope extrusion structure with temperature control function. Utility Model Content

[0010] Preferably, a plurality of stirring rods are fixedly connected to the middle of the first screw; the stirring rods are distributed in a linear array; through the above structure, the material inside the extrusion cylinder can be effectively stirred, so that the material in different parts can be fully mixed.

[0011] Preferably, a rubber gasket is slidably connected to the middle of the bolt; the rubber gasket is located between the first flange and the nut; through the above structure, the friction between the first flange and the nut can be effectively increased, making the connection between the first flange and the second flange more secure.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The optical cable filling rope extrusion structure with temperature control function described in this utility model heats the material by setting a temperature control box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4 As shown in the figure, an optical cable filling rope extrusion structure with temperature control function according to an embodiment of the present invention includes a base plate 1; an extrusion cylinder 11 is fixedly connected to the top of the base plate 1; a first motor 12 is fixedly connected to the side wall of the extrusion cylinder 11; a connecting seat 13 is fixedly connected inside the extrusion cylinder 11; a first screw 14 is rotatably connected inside the connecting seat 13, and the first screw 14 is connected to the output end of the first motor 12; the first screw 14 is wavy in shape; two temperature control boxes 15 are fixedly connected to the middle of the base plate 1; the two temperature control boxes 15 are symmetrically arranged; a die head assembly 16 is fixedly connected to the end of the temperature control box 15; a feeding assembly 17 is fixedly connected to the middle of the base plate 1; the feeding assembly 17 is located at one end near the first motor 12; During operation, the material enters the extrusion cylinder 11 through the feeding assembly 17. The first motor 12 is started, and the first motor 12 drives the first screw 14 to rotate inside the connecting seat 13. As the first screw 14 rotates, it drives the material to flow. The temperature control box 15 is adjusted to a suitable temperature, and the temperature control box 15 heats the material to melt it. The melted material flows along the first screw 14 and into the die assembly 16, and is then extruded from the die assembly 16. Through the above structure, the material temperature is made uniform and stable during the extrusion process, which effectively improves the dimensional accuracy and appearance quality of the extruded product. The first screw 14 is wavy, which effectively increases the disturbance amplitude of the material and greatly improves the mixing effect, thereby making the extrusion of the material more uniform and stable.

[0026] like Figure 1 and Figure 4As shown, the die assembly 16 includes a first flange 2; multiple bolts 21 are slidably connected inside the first flange 2; the bolts 21 are distributed in a circumferential array; a second flange 22 is slidably connected to the center of the bolts 21; an extrusion head 23 is fixedly connected inside the second flange 22; a nut 24 is threadedly connected to the center of the bolts 21; the nut 24 contacts the side wall of the first flange 2; during operation, different extrusion heads 23 are required when the diameter of the filling rope produced is different. By rotating the nut 24, it is removed from the bolt 21, and the sliding bolt 21 is used to pull it out from inside the first flange 2 and the second flange 22, thereby separating the extrusion head 23 from the extrusion cylinder 11. The new extrusion head 23 is then connected to the first flange 2 and fixed by the bolts 21 and the nut 24. Through the above structure, the extrusion head 23 can be quickly installed and disassembled, greatly improving work efficiency and facilitating the replacement of the extrusion head 23. This allows the extrusion structure to adapt to different production needs and effectively improves the flexibility of the extrusion structure.

[0027] like Figures 1 to 3 As shown, the feeding assembly 17 includes a feeding pipe 3; a hopper 31 is fixedly connected to the top of the feeding pipe 3; a fixing plate 32 is fixedly connected to the top of the hopper 31; a second motor 33 is fixedly connected to the top of the fixing plate 32; a second screw 34 is rotatably connected to the bottom of the fixing plate 32; and the second screw 34 is connected to the output end of the second motor 33. During operation, the second motor 33 is started when feeding, and the second motor 33 drives the second screw 34 to rotate at the bottom of the fixing plate 32. When the second motor 33 rotates, it drives the material to flow into the inside of the feeding pipe 3, and the material then flows into the extrusion cylinder 11 through the feeding pipe 3. Through the above structure, the material can be fed evenly in an effective manner, so that the material supply during the extrusion process is stable, thereby ensuring the consistency of the filling rope quality, and the material can be smoothly transported into the inside of the extrusion cylinder 11, reducing the material blockage during the conveying process.

[0028] like Figure 3 As shown, a plurality of stirring rods 4 are fixedly connected to the middle of the first screw 14; the stirring rods 4 are distributed in a linear array; during operation, the stirring rods 4 are set in the middle of the first screw 14, and the stirring rods 4 will rotate when the first screw 14 rotates. Through the above structure, the material inside the extrusion cylinder 11 can be effectively stirred, so that the material in different parts can be fully mixed, improving the uniformity of the material and further enhancing the mixing effect of the material.

[0029] like Figure 4As shown, a rubber gasket 5 is slidably connected to the middle of the bolt 21; the rubber gasket 5 is located between the first flange 2 and the nut 24; during operation, the rubber gasket 5 is provided on the bolt 21, and the rubber gasket 5 is located between the first flange 2 and the nut 24. Through the above structure, the friction between the first flange 2 and the nut 24 can be effectively increased, making the connection between the first flange 2 and the second flange 22 more secure, which helps to improve the extrusion effect of the filling rope.

[0030] like Figure 1 As shown, a protective cover 6 is fixed to the top of the fixing plate 32; the protective cover 6 is set at a position corresponding to the second motor 33; during operation, materials may splash onto the second motor 33. By setting the protective cover 6 on the outside of the fixing plate 32, the material entering the second motor 33 can be effectively reduced, the wear of the material on the second motor 33 can be reduced, and the service life of the second motor 33 can be improved.

[0031] like Figure 1 As shown, a bracket 7 is fixedly connected to the middle of the first motor 12; the bracket 7 is fixedly connected to the top of the base plate 1; during operation, the first motor 12 may vibrate. By setting the bracket 7 in the middle of the first motor 12, the first motor 12 can be effectively supported through the above structure, reducing the amplitude of its vibration, thereby maintaining the stable operation of the first motor 12.

[0032] During operation, the material enters the extrusion cylinder 11 through the feeding assembly 17. The first motor 12 is started, driving the first screw 14 to rotate inside the connecting seat 13. As the first screw 14 rotates, it causes the material to flow. The temperature control box 15 is adjusted to a suitable temperature, heating the material until it melts. The melted material flows along the first screw 14 into the die assembly 16, and is then extruded from the die assembly 16. This structure ensures a uniform and stable material temperature during extrusion, effectively improving the dimensional accuracy and appearance quality of the extruded product. The wavy design of the first screw 14 effectively increases the agitation amplitude of the material, greatly improving the mixing effect and resulting in more uniform material extrusion. To ensure uniform and stable production, different extrusion heads 23 are required when the diameter of the filling rope being produced varies. Rotating the nut 24 removes the extrusion head 23 from the bolt 21, and sliding the bolt 21 pulls it out from inside the first flange 2 and the second flange 22, thus separating the extrusion head 23 from the extrusion cylinder 11. A new extrusion head 23 is then connected to the first flange 2 and secured with bolts 21 and nuts 24. This structure allows for quick installation and disassembly of the extrusion head 23, greatly improving work efficiency and facilitating replacement. This allows the extrusion structure to adapt to different production needs, effectively increasing its flexibility. During feeding, the second motor 33 is activated, driving the second screw 34 to move at the bottom of the fixed plate 32. When the first screw 14 rotates, the second motor 33 drives the material to flow into the feed pipe 3, and then the material flows into the extrusion cylinder 11 through the feed pipe 3. This structure effectively ensures uniform feeding, maintaining a stable material supply during extrusion and guaranteeing consistent filler rope quality. It also ensures smooth material delivery to the extrusion cylinder 11, reducing material blockage during transport. A stirring rod 4 is installed in the middle of the first screw 14. When the first screw 14 rotates, it drives the stirring rod 4 to rotate. This structure effectively stirs the material inside the extrusion cylinder 11, allowing for thorough mixing of materials from different parts, improving material uniformity, and further enhancing the mixing effect. Rubber is installed on the bolt 21. Gasket 5, a rubber gasket 5, is located between the first flange 2 and the nut 24. This structure effectively increases the friction between the first flange 2 and the nut 24, making the connection between the first flange 2 and the second flange 22 more secure and improving the extrusion effect of the filling rope. Material may splash onto the second motor 33; a protective cover 6 is installed outside the fixing plate 32. This structure effectively reduces the amount of material entering the second motor 33, reducing wear and tear and thus extending its service life. The first motor 12 may vibrate; a bracket 7 is installed in the middle of the first motor 12. This structure effectively supports the first motor 12 and reduces the amplitude of its vibration.This ensures the stable operation of the first motor 12.
