Description

Technical Field

[0001] This invention relates to the field of silicon core tube production technology, and in particular to a winding device for producing wear-resistant HDPE silicon core tubes. Background Technology

[0002] Wear-resistant HDPE silicon core pipe is a conduit material specifically designed for laying communication optical cables (especially FTTH drop cables). It primarily uses high-density polyethylene (HDPE) as the base material, with a smooth silicone coating pre-installed inside. This design makes the pipe's interior extremely smooth, significantly reducing frictional resistance during cable insertion and enabling rapid, one-step installation, effectively protecting the cable from damage. Simultaneously, HDPE itself possesses excellent corrosion resistance, aging resistance, and a certain level of mechanical strength, while the silicon core layer also exhibits good wear resistance, ensuring the pipe's long-term stability and reliability in complex environments such as underground locations.

[0003] In the traditional production process of wear-resistant HDPE silicon core tubes, the winding process is an indispensable step. However, existing winding equipment has certain limitations in operation. Typically, to ensure that the silicon core tube has sufficient rigidity and dimensional stability during winding and to prevent deformation or damage due to overheating or oversoftening, further surface cooling is required on the tube that has just been extruded from the extruder and has undergone preliminary cooling. In addition, to achieve uniform distribution and tight arrangement of the tube on the core and avoid uneven thickness or looseness in the middle, traditional winding equipment often needs to be equipped with an additional drive mechanism to enable the winding roller to slide horizontally back and forth. However, this additional mechanical movement not only increases the complexity of the equipment but also directly leads to additional energy consumption, leaving room for improvement in the energy efficiency of the entire winding process. Summary of the Invention

[0004] One objective of this invention is to provide a winding device for the production of wear-resistant HDPE silicon core tubes. This invention addresses the problem mentioned in the background that existing winding devices require additional cooling steps and complex reciprocating drive mechanisms, leading to a more complex equipment structure. These additional processes and movements consume more energy, resulting in low overall energy efficiency in the winding process.

[0005] A wear-resistant HDPE silicon core tube production winding device according to an embodiment of the present invention includes: A cooling mechanism, comprising a pump, cooling pipes, and a water collection tank, wherein the pump is fixedly installed on one side of the water collection tank, the cooling pipes are fixedly installed on the upper part of the water collection tank, and a drain pipe is fixedly installed on the lower part of the cooling pipes; The transmission mechanism includes a rotating shaft and a transmission rod. Both the rotating shaft and the transmission rod are rotatably mounted inside the water collection tank via a fixed block. A waterwheel is fixedly mounted on the surface of the rotating shaft. A first bevel gear is fixedly mounted on one end of the rotating shaft. A second bevel gear and a third bevel gear are fixedly mounted on both ends of the transmission rod, respectively. A reciprocating swing mechanism, comprising a reciprocating lead screw and a sliding rod, wherein a fixed base is fixedly installed on one side of the water collection tank, a sliding groove is provided on the upper surface of the fixed base, the reciprocating lead screw is rotatably installed inside the sliding groove, a fourth bevel gear is fixedly installed at one end of the reciprocating lead screw, the sliding rod is threaded onto the surface of the reciprocating lead screw, and a fixed bracket is fixedly installed at the upper end of the sliding rod; A winding mechanism, comprising a movable support and a winding roller, wherein the movable support is movably mounted on one side of a fixed support, and the winding roller is movably mounted inside the movable support and the fixed support.

[0006] Preferably, a water pumping pipe is fixedly installed at the lower end of the pump, a water delivery pipe is fixedly installed at the upper end of the pump, and the other end of the water delivery pipe is fixedly installed at the upper part of the cooling pipe.

[0007] Preferably, the cooling pipe has a silicon core tube body extruded from the extruder running through it.

[0008] Preferably, the first bevel gear and the second bevel gear mesh with each other, and the rotating shaft drives the transmission rod to rotate synchronously through the first bevel gear and the second bevel gear.

[0009] Preferably, the third bevel gear and the fourth bevel gear mesh with each other, and the transmission rod drives the reciprocating screw to rotate synchronously through the third bevel gear and the fourth bevel gear.

[0010] Preferably, a limiting block is fixedly installed at the end of the reciprocating screw away from the fourth bevel gear to limit the sliding distance of the sliding rod inside the sliding groove.

[0011] Preferably, a movable bracket is movably mounted on one side of the fixed bracket via a telescopic rod, and a spring structure is installed between the movable bracket and the fixed bracket.

[0012] Preferably, a drive motor is fixedly installed on the upper outer side of the fixed bracket, and a locking block is installed at the output end of the drive motor through an output shaft.

[0013] Preferably, baffles are fixedly installed on both sides of the surface of the take-up roller.

[0014] Preferably, a limiting groove is formed on one side surface of the take-up roller, and the shape and size of the limiting groove are the same as those of the output shaft and the locking block.

[0015] The beneficial effects of this invention are: This invention utilizes a cooling mechanism, a transmission mechanism, and a reciprocating oscillating mechanism. After the wear-resistant HDPE silicon core tube is extruded, it directly enters the cooling pipe of the cooling mechanism. A pump delivers cooling water from the water collection tank into the cooling pipe to cool and shape the wear-resistant HDPE silicon core tube. Subsequently, the water flows downward through the drain pipe. As the water flows into the water collection tank, it impacts the water cart, causing the water cart and rotating shaft to rotate. The rotating shaft drives the transmission rod to rotate via the first bevel gear. The transmission rod drives the fourth bevel gear and the reciprocating screw to rotate via the third bevel gear. When the reciprocating screw rotates, it drives the sliding rod threaded on the surface of the reciprocating screw to slide back and forth in the upper part of the sliding groove. Finally, it drives the winding mechanism above to wind up the wear-resistant HDPE silicon core tube. This achieves automatic cooling and efficient winding of the wear-resistant HDPE silicon core tube, simplifies the equipment structure, reduces additional energy consumption, improves overall energy efficiency, and avoids the complex cooling and driving problems of traditional winding devices. This invention utilizes a cooling mechanism. During operation, a pump from the cooling mechanism pumps cooling water from the collection tank into the cooling pipes via a suction pipe and a delivery pipe to cool the wear-resistant HDPE silicon core tubes. The water then flows downwards through a drain pipe, impacting the surface of the water cart. This provides power to the reciprocating oscillating mechanism and simultaneously cools the cooling water entering the collection tank. This lowers the temperature of the cooling water, allowing it to be pumped back into the cooling pipes for continued cooling of the wear-resistant HDPE silicon core tubes, thus achieving recycling. This reduces energy consumption, improves cooling efficiency, and simplifies the equipment structure. This invention utilizes a winding mechanism where a winding roller is installed inside a fixed bracket and a movable bracket during use. A drive motor rotates the output shaft and a locking block, which engage with the limiting groove, causing the winding roller to rotate and thus winding the wear-resistant HDPE silicon core tube. When the winding roller is fully wound and needs to be removed, the movable bracket is pulled outward, stretching the telescopic rod and spring structure, allowing the winding roller to be removed directly from the fixed bracket and its inner side. After inserting a new winding roller, the movable bracket is released, and the spring structure and the telescopic rod's restoring force push the movable bracket towards the fixed bracket, securing the new winding roller. This convenient replacement of the winding roller using the telescopic rod and spring structure significantly improves winding efficiency, simplifies the operation process, ensures stability and reliability during winding, and greatly enhances the convenience of equipment maintenance and production.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0018] refer to Figure 1-7 A wear-resistant HDPE silicon core tube production winding device includes the following embodiments: Example 1: Cooling mechanism 1 includes a pump 101, cooling pipes 105, and a water collection tank 107. The pump 101 is fixedly installed on one side of the water collection tank 107, the cooling pipes 105 are fixedly installed on the upper part of the water collection tank 107, and a drain pipe 104 is fixedly installed on the lower part of the cooling pipes 105. A water suction pipe 103 is fixedly installed at the lower end of the pump 101, and a water delivery pipe 102 is fixedly installed at the upper end of the pump 101. The other end of the water delivery pipe 102 is fixedly installed on the upper part of the cooling pipes 105. A silicon core tube body 106 extruded from an extruder is inserted through the interior of the cooling pipes 105. During use, the pump 101 of the cooling mechanism 1 pumps water from the water collection tank... The cooling water inside 107 is sent into the cooling pipe 105 through the pumping pipe 103 and the supply pipe 102 to cool the wear-resistant HDPE silicon core tube. After cooling the tube, the water flows downward through the drain pipe 104. As the water flows downward along the drain pipe 104, it impacts the surface of the water cart 203. On the one hand, this provides a power source for the reciprocating swing mechanism 3, and on the other hand, it cools the cooling water, reducing the temperature of the cooling water entering the water collection tank 107. This makes it easier to send the water back into the cooling pipe 105 through the pump 101 to continue cooling the wear-resistant HDPE silicon core tube, thus achieving recycling. This reduces energy consumption, improves cooling efficiency, and simplifies the equipment structure.

[0019] Example 2: Transmission mechanism 2 includes a rotating shaft 202 and a transmission rod 206. Both the rotating shaft 202 and the transmission rod 206 are rotatably mounted inside the water collection tank 107 via a fixing block 201. A waterwheel 203 is fixedly mounted on the surface of the rotating shaft 202. A first bevel gear 204 is fixedly mounted at one end of the rotating shaft 202, and a second bevel gear 205 and a third bevel gear 207 are fixedly mounted at both ends of the transmission rod 206, respectively. The first bevel gear 204 and the second bevel gear 205 mesh with each other, and the rotating shaft 202 drives the transmission rod 206 to rotate synchronously through the first bevel gear 204 and the second bevel gear 205. The third bevel gear 207 and the fourth bevel gear 208 mesh with each other, and the transmission rod 206 drives the reciprocating screw 302 to rotate synchronously through the third bevel gear 207 and the fourth bevel gear 208. Through the cooling mechanism 1, transmission mechanism 2, and reciprocating oscillating mechanism 3, the wear-resistant HDPE silicon core tube directly enters the cooling pipe 105 of the cooling mechanism 1 after being extruded by the extruder. Pump 101 delivers cooling water from the water collection tank 107 into the cooling pipe 105 to cool and heat the wear-resistant HDPE silicon core tube for molding. The water then flows downwards through the drain pipe 104. As the water flows into the water collection tank 107, it impacts the water wheel 203, causing the water wheel 203 and the rotating shaft 202 to rotate. The rotating shaft 202 drives the transmission rod 206 to rotate via the first bevel gear 204, and the transmission rod 206 drives the fourth bevel gear via the third bevel gear 207. The wheel 208 and the reciprocating screw 302 rotate. When the reciprocating screw 302 rotates, it drives the sliding rod 303, which is threaded onto the surface of the reciprocating screw 302, to slide back and forth in the upper part of the sliding groove 301. Finally, it drives the winding mechanism 4 above to wind up the wear-resistant HDPE silicon core tube. This achieves automatic cooling and efficient winding of the wear-resistant HDPE silicon core tube, simplifies the equipment structure, reduces additional energy consumption, improves overall energy efficiency, and avoids the complex cooling and driving problems of traditional winding devices.

[0020] Example 3: The reciprocating swing mechanism 3 includes a reciprocating lead screw 302 and a sliding rod 303. A fixed base 305 is fixedly installed on one side of the water collection tank 107. A sliding groove 301 is opened on the upper surface of the fixed base 305. The reciprocating lead screw 302 is rotatably installed inside the sliding groove 301. A fourth bevel gear 208 is fixedly installed at one end of the reciprocating lead screw 302. The sliding rod 303 is threaded onto the surface of the reciprocating lead screw 302. A fixed bracket 304 is fixedly installed at the upper end of the sliding rod 303. A limiting block is fixedly installed at the end of the reciprocating lead screw 302 away from the fourth bevel gear 208 to limit the sliding distance of the sliding rod 303 inside the sliding groove 301.

[0021] Example 4: The winding mechanism 4 includes a movable support 401 and a winding roller 407. The movable support 401 is movably mounted on one side of the fixed support 304, and the winding roller 407 is movably mounted inside the movable support 401 and the fixed support 304. The movable support 401 is movably mounted on one side of the fixed support 304 via a telescopic rod 402. A spring structure 403 is installed between the movable support 401 and the fixed support 304. A drive motor 404 is fixedly mounted on the upper outer side of the fixed support 304. A locking block 406 is installed at the output end of the drive motor 404 via an output shaft 405. Baffles 409 are fixedly mounted on both sides of the surface of the winding roller 407. A limit groove 408 is formed on one side surface of the winding roller 407. The shape and size of the limit groove 408 are the same as the shape and size of the output shaft 405 and the locking block 406. With the winding mechanism 4, the winding roller 407 is installed inside the fixed support 304 and the movable support 401 during use, and driven by the drive motor 401... 04 drives the output shaft 405 and the locking block 406 to rotate. The locking block 406 and the output shaft 405 are locked inside the limiting groove 408, thereby driving the take-up roller 407 to rotate, achieving the purpose of winding the wear-resistant HDPE silicon core tube. When the take-up roller 407 is fully wound and needs to be removed, the movable bracket 401 is pulled outward, the telescopic rod 402 and the spring structure 403 are stretched, and the take-up roller 407 can be directly removed from the fixed bracket 304 and the inside of the fixed bracket 304. After that, a new take-up roller 407 is installed and the movable bracket 401 is released. The restoring elasticity of the spring structure 403 and the telescopic rod 402 causes the movable bracket 401 to be pressed towards the fixed bracket 304, realizing the locking and fixing of the new take-up roller 407. The telescopic rod 402 and the spring structure 403 realize the convenient replacement of the take-up roller 407, which significantly improves the winding efficiency, simplifies the operation process, and ensures the stability and reliability of the winding process, greatly improving the convenience of equipment maintenance and production.

[0022] In use, the high-temperature silicon core tube body 106 extruded from the extruder directly enters the cooling pipe 105. The pump 101 draws cooling water from the water collection tank 107 through the water suction pipe 103 and delivers the cooling water to the upper part of the cooling pipe 105 through the water delivery pipe 102. The water flows from top to bottom over the surface of the silicon core tube body 106 for forced cooling. After heat exchange, the cooling water returns to the water collection tank 107 through the drain pipe 104. During this process, the high-speed water flow from the drain pipe 104 impacts the blades of the water car 203, causing the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 is transmitted to the second bevel gear 205 through the first bevel gear 204, driving the transmission rod 206 to rotate. The third bevel gear 207 and the fourth bevel gear 208 at the other end of the rod 206 mesh, transmitting power to the reciprocating screw 302. When the reciprocating screw 302 rotates in the sliding groove 301, it drives the threaded sliding rod 303 to perform linear reciprocating motion. The fixed bracket 304 on the upper part of the sliding rod 303 moves synchronously, realizing the reciprocating swing of the winding mechanism 4. During the winding process, the drive motor 404 drives the locking block 406 to rotate through the output shaft 405. The locking block 406 cooperates with the limiting groove 408 on the winding roller 407, driving the winding roller 407 to rotate. The baffles 409 on both sides of the winding roller 407 ensure that the silicon core tube is neatly wound. When winding is completed, the winding roller 407 needs to be replaced. When the operator pulls the movable support 401 outward, the telescopic rod 402 and the spring structure 403 are stretched, allowing the fully wound take-up roller 407 to be easily removed. After inserting the new take-up roller 407, the movable support 401 is released, and the rebound force of the spring structure 403 causes the movable support 401 to automatically reset, firmly locking the new take-up roller 407 between the fixed support 304 and the movable support 401. The entire device forms a complete automated working cycle: cooling water circulates between the water collection tank 107, the pump 101, and the cooling pipe 105, achieving continuous cooling of the silicon core tube and driving the transmission system through water flow power; the transmission mechanism 2 converts the kinetic energy of the water flow into mechanical energy, driving... The reciprocating oscillating mechanism 3 and the winding mechanism 4 complete the uniform winding of the silicon core tube while reciprocating. Through ingenious mechanical linkage design, this device achieves the organic unity of four major functions: cooling, transmission, oscillation and winding. It not only simplifies the equipment structure but also significantly improves energy utilization efficiency and ease of operation. The water circulation system serves as both a cooling medium and a power source for mechanical movement, realizing the cascade utilization of energy. The quick-change design of the winding mechanism 4 greatly improves production efficiency and ensures the continuity of the production process. The entire system operates stably and reliably, with each component coordinating and working together, perfectly solving the technical problems of low cooling efficiency, high energy consumption and complex operation in traditional silicon core tube production.
