Description

Technical Field

[0001] This invention relates to the field of plastic molding extrusion equipment technology, specifically to an extruder auxiliary traction device for preventing cable vibration. Background Technology

[0002] In the cable extrusion production process, the traction device is a core and critical piece of equipment connecting extrusion molding and cooling / winding. Its operational stability and pressure uniformity directly determine the appearance quality, dimensional accuracy, and insulation performance of the finished cable. Currently, the mainstream in the industry adopts a traction structure with two sets of transverse conveyor belts clamping the cable. Compared to traditional single-roller traction equipment, this increases the contact area with the cable, avoiding localized deformation caused by single-point pressure on the cable. It is effectively adapted to continuous extrusion traction operations for long-length, large-diameter cables, and is therefore widely used in various wire and cable extrusion production lines.

[0003] Currently, conventional conveyor belt traction devices all employ a closed-loop transmission mechanism with driving and driven wheels at both ends, leaving the middle section of the conveyor belt suspended and loose. To address the issues of mid-section collapse and insufficient traction, existing technologies typically add several auxiliary drive wheels in the middle section for support and restraint. However, this improvement method has significant drawbacks in practical production applications: First, the densely arranged auxiliary drive wheels in the middle section significantly increase the overall transmission resistance, making it difficult to achieve perfect matching of multiple wheels' synchronous rotation, easily leading to jamming and other problems, resulting in unstable conveyor belt operation and causing cable conveying vibration; Second, the direct rigid contact between the auxiliary drive wheels and the conveyor belt causes the corresponding drive wheel positions to bulge under pressure, while the positions without drive wheels are relatively concave, resulting in extremely uneven distribution of the clamping and compressing force on the cable. This leads to differentiated stress conditions, with some areas being excessively tight and others loose, causing irregular indentations on the cable's surface insulation sheath. Meanwhile, existing conveyor belt traction structures only have a single traction and conveying function. After the cable is extruded, the temperature is high, requiring it to be bent separately and introduced into a special cooling water tank for immersion cooling and shaping. This production process causes bending angles in the cable conveying path, completely disrupting the continuous horizontal stretching of the cable after extrusion, which can easily lead to quality defects such as cable stretching deformation, eccentricity, and sheath wrinkles. Summary of the Invention

[0004] The purpose of this invention is to provide an extruder auxiliary traction device that facilitates flexible and uniform clamping of the entire conveyor belt, reduces conveyor vibration and cable deformation, and simultaneously and gently cools the cable with water, ensuring horizontal conveying and cooling throughout the entire process to prevent cable vibration, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an extruder auxiliary traction device for preventing cable vibration, comprising an extruder, a support, a conveying mechanism, a traction mechanism, and a cooling mechanism. A water tank is fixedly connected to the support. The conveying mechanism is installed on the support for conveying cables and raw materials. The traction mechanism includes an upper conveyor belt and a lower conveyor belt installed in the water tank. Baffles are respectively provided on both sides of the upper and lower conveyor belts. The traction mechanism can transport cooling water in the water tank between the baffles on both sides to fill and pressurize the inner walls of the upper and lower conveyor belts, so that the upper... The middle section of the conveyor belt and the lower conveyor belt fits tightly against the outer wall of the cable and provides elastic cushioning, improving the anti-vibration effect and the fit strength. At the same time, the water overflowing from the baffle between the upper and lower conveyor belts can flow around the cable for auxiliary cooling. The cooling mechanism is installed on the water tank and is used to pump the water in the water tank to the upper side of the cable and flow down along the outer wall of the cable to complete the cooling.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-10The diagram illustrates an extruder auxiliary traction device for preventing cable vibration. It includes an extruder 1, a support 2, a conveying mechanism, a traction mechanism, and a cooling mechanism. A water tank 3 is fixedly connected to the support 2. The conveying mechanism is mounted on the support 2 and is used to convey the cable 37 and raw materials. The traction mechanism includes an upper conveyor belt 4 and a lower conveyor belt 5 installed within the water tank 3. Baffles 6 are provided on both sides of the upper and lower conveyor belts 4 and 5. The traction mechanism can transport cooling water from the water tank 3 to the space between the baffles 6, filling and pressurizing the inner walls of the upper and lower conveyor belts 4 and 5. This ensures that the middle portion of the upper and lower conveyor belts 4 and 5 is tightly fitted against the outer wall of the cable 37, providing elastic cushioning and improving the anti-vibration effect and fit strength. Simultaneously, water overflowing from between the baffles 6 and the upper and lower conveyor belts 4 and 5 can flow to the vicinity of the cable 37 for auxiliary cooling. The cooling mechanism is mounted on the water tank 3 and is used to pump water from the water tank 3 to the upper side of the cable 37 and... The water flows downwards along the outer wall of cable 37 to complete the cooling process, preventing cable 37 from bending during transport and preventing water from damaging the outer wall of cable 37. The traction mechanism also includes a fixed frame 7 and a guide frame 8 fixedly installed on the upper side of the water tank 3. The inner walls of both ends of the upper conveyor belt 4 and the lower conveyor belt 5 are respectively connected to a drive wheel 9 and a driven wheel 10. The two ends of the drive wheel 9 and the driven wheel 10 are respectively rotatably connected to a baffle 6. The baffle 6 is provided with a sealing element to improve the sealing effect between the upper conveyor belt 4 and the lower conveyor belt 5. The guide frame 8 is provided with an adjusting element to adjust the distance between the upper conveyor belt 4 and the lower conveyor belt 5. The fixed frame 7 is provided with a driving element to drive the drive wheel 9 to rotate. The fixed frame 7 is provided with a conveying element to pump the water in the water tank 3 to the inner walls of the upper conveyor belt 4 and the lower conveyor belt 5. The driving element includes a drive motor 11 fixedly installed on the fixed frame 7. The drive motor 11 is preferably a variable frequency speed-regulating three-phase asynchronous motor with a rated power of 1.The motor has a power rating of 5kW to 3kW (specific power depends on cable specifications and traction speed), and is used in conjunction with a reducer to ensure sufficient traction torque and speed range. The output end of the drive motor 11 is coaxially fixedly connected to a drive shaft 12. Two sets of worm gears 13 are fixedly connected to the outer wall of the drive shaft 12, with opposite thread directions. One end of each of the upper and lower drive wheels 9 is coaxially fixedly connected to a worm wheel 14 that meshes with the worm gear 13. The conveying component includes a pressure pump 19 fixedly mounted on a fixed frame 7. The input end of the pressure pump 19 is connected to a first inlet pipe 20, and the output end of the pressure pump 19 is connected to two first outlet pipes 21. The first water outlet pipe 21 is fixedly connected to the sides of the upper and lower sets of baffles 6 respectively. The first water outlet pipe 21 passes through the baffles 6 and can transport water to the internal areas of the upper conveyor belt 4 and the lower conveyor belt 5. The sealing element includes multiple sets of sealing plates 26 installed on the baffles 6. Sliding grooves 27 are respectively opened on the upper and lower sides of the baffles 6. The sealing plates 26 are slidably connected to the inner walls of the sliding grooves 27 in the horizontal direction. The sides of the upper conveyor belt 4 and the lower conveyor belt 5 are slidably attached to the edges of the sealing plates 26 respectively. The sides of the sealing plates 26 are fixedly connected to elastic elements 28 that are fixedly connected to the sliding grooves 27. The elastic elements 28 can be any existing elastic structure such as springs, with preferential replacement. In this alternative, the conveying mechanism includes a wire feeding mechanism 35 fixedly mounted on the bracket 2. The extruder 1 is equipped with a feed hopper 36. A vertically arranged worm gear 13 drives a worm wheel 14 to rotate, which improves the stability of the drive and allows the worm wheel 14 to roll along the outer wall of the worm gear 13 when adjusting the distance between the upper conveyor belt 4 and the lower conveyor belt 5, without affecting the transmission connection between the worm wheel 14 and the worm gear 13. A pressure pump 19 draws and pressurizes water from the water tank 3 through the first water inlet pipe 20 and delivers it to the first water outlet pipe 21. The pressurized water is then delivered to the upper conveyor belt 4 and the lower conveyor belt 5 through two sets of first water outlet pipes 21. The inner wall of the baffle 6 causes the middle section of the upper conveyor belt 4 and the lower conveyor belt 5 to be lifted up. Through the sealing plates 26 located on the upper and lower sides of the baffle 6, the sealing plates 26, pushed by the elastic element 28, reduce the gap between themselves and the upper and lower conveyor belts 4 and 5. This allows the middle section of the upper and lower conveyor belts 4 and 5 to be stably lifted by water pressure, increasing the contact strength with the outer wall of the cable 37 and improving stability during transport. Simultaneously, because the internal structure is supported and driven by water pressure, the upper and lower conveyor belts 4 and 5 can swing slightly to absorb energy, buffering the vibrations during cable 37 transport and ensuring stability during transport.

[0020] Example 2: Please refer to Figures 1-6This embodiment further illustrates Embodiment 1. The cooling mechanism shown in the figure includes a fixed frame 15 fixedly installed within a fixed bracket 7. A triangular groove 16 is fixedly connected within the fixed frame 15. An output groove 17 is formed at the bottom end of the triangular groove 16. Guide cloths 18 are fixedly connected to both sides of the output groove 17. The bottom sidewall of the guide cloth 18 slides against the cable 37 to guide the water flow. The fixed bracket 7 is equipped with a pumping component for pumping water from the water tank 3 into the triangular groove 16. The pumping component includes a delivery pump 32 fixedly installed within the fixed bracket 7. The input end of the delivery pump 32 is connected to the second inlet pipe 33, and the output end of the delivery pump 32 is connected to the second outlet pipe 34. The second inlet pipe 33 is connected to the water tank 3, and the second outlet pipe 34 is connected to the triangular groove 16. The delivery pump 32 draws water from the water tank 3 into the fixed frame 15 and the triangular groove 16 through the second inlet pipe 33 and discharges it through the second outlet pipe 34. The water flows out from the output groove 17 at the bottom of the triangular groove 16. After being guided by the guide cloth 18, the water flows downward along the outer wall of the cable 37 to complete the slow flow cooling operation.

[0021] Example 3: Please refer to Figures 4-10 This embodiment further illustrates Embodiment 1. The adjusting component shown in the figure includes a guide block 22 fixedly installed on the side of the baffle 6. Guide grooves 23 are respectively opened on both sides of the inner wall of the guide frame 8. The guide block 22 is slidably connected to the inner wall of the guide groove 23 in the vertical direction. A rotating rod 24 is rotatably connected in the guide groove 23. Two sets of threaded grooves 25 with opposite thread directions are opened on the rotating rod 24. The rotating rod 24 passes through the guide block 22. The upper and lower guide blocks 22 are respectively threadedly connected to the threaded grooves 25 with opposite thread directions. A first gear 29 is rotatably connected to the guide frame 8. The upper end of the rotating rod 24 is coaxially fixedly connected to... The second gear 30 meshes with the first gear 29. A knob 31 is coaxially fixedly connected to the upper side of the first gear 29. By rotating the knob 31, the first gear 29 drives the second gears 30 on both sides to rotate. The second gears 30 drive the rotating rod 24 to rotate, thereby causing the upper and lower guide blocks 22 to move in opposite directions under the drive of the threaded grooves 25 with opposite thread directions. This drives the upper and lower baffles 6 to move and open, adjust the distance between the upper conveyor belt 4 and the lower conveyor belt 5, and ensure that the minimum distance between the two ends of the upper conveyor belt 4 and the lower conveyor belt 5 is greater than the diameter of the cable 37, so as to avoid direct compression of the cable 37 and deformation.

[0022] Working principle: The wire core to be processed is fed to the output end of the extruder 1 through the wire feeding mechanism 35. The extruder 1 melts the extruded raw material in the feed hopper 36 and extrudes it evenly to wrap around the outer wall of the wire core. The output cable 37 passes horizontally above the water tank 3. By rotating the knob 31, the first gear 29 drives the second gears 30 on both sides to rotate. The second gears 30 drive the rotating rod 24 to rotate, so that the upper and lower guide blocks 22 move in opposite directions under the drive of the threaded grooves 25 with opposite thread directions. This drives the upper and lower baffles 6 to move and open, adjusting the distance between the upper conveyor belt 4 and the lower conveyor belt 5, and ensuring that the minimum distance between the two ends of the upper conveyor belt 4 and the lower conveyor belt 5 is greater than the wire core. The diameter of cable 37 is designed to prevent direct compression and deformation. During use, the drive motor 11 drives the drive shaft 12 to rotate, which in turn drives the upper and lower worm gears 13 to rotate synchronously. This causes the upper and lower worm wheels 14 to rotate synchronously in opposite directions. The worm wheels 14 drive the drive wheel 9 to rotate, thus enabling the upper conveyor belt 4 and the lower conveyor belt 5 to simultaneously transport the cable 37 in the middle position. The vertically arranged worm gear 13 drives the worm wheel 14 to rotate, which improves the stability of the drive and allows the worm wheel 14 to roll along the outer wall of the worm gear 13 when adjusting the distance between the upper conveyor belt 4 and the lower conveyor belt 5, without affecting the transmission connection between the worm wheel 14 and the worm gear 13.

[0023] Water from the tank 3 is pumped and pressurized by the pressure pump 19 through the first inlet pipe 20 and delivered to the first outlet pipe 21. The pressurized water is then delivered to the inner walls of the upper conveyor belt 4 and the lower conveyor belt 5 through two sets of first outlet pipes 21, causing the middle sections of the upper and lower conveyor belts 4 and 5 to be lifted. The sealing plates 26 on the upper and lower sides of the baffle 6, pushed by the elastic element 28, reduce the gap between the sealing plates 26 and the upper and lower conveyor belts 4 and 5, allowing the middle sections of the upper and lower conveyor belts 4 and 5 to be stably lifted by water pressure. This increases the contact strength with the outer wall of the cable 37, improving stability during transport. Simultaneously, the internal water pressure support allows the upper and lower conveyor belts 4 and 5 to oscillate slightly to absorb energy, buffering the vibrations of the cable 37 during transport and ensuring the cable 37 remains stable. 7. Stability during the conveying process: Due to the gaps on both sides of the upper conveyor belt 4 and the lower conveyor belt 5 during the transmission process, the internal water pressure will continuously leak out from the gaps as it increases. The water flowing out from the gaps will flow onto the lower conveyor belt 5. The middle of the cross-section of the upper conveyor belt 4 and the lower conveyor belt 5 is concave, which improves the wrapping of the outer wall of the cable 37 during the conveying process. It can also help retain water on the lower conveyor belt 5, so that the cable 37 can be cooled by the water during the horizontal conveying process. The water is constantly flowing, and the lower conveyor belt 5 will also continuously transport the retained water to one end and discharge it into the water tank 3. This ensures that the water around the cable 37 is always at a suitable temperature. The water tank 3 is equipped with a circulating cooling device, which can ensure that the water inside the water tank 3 is always clean and at a suitable temperature.

[0024] Water from the water tank 3 is pumped in through the second inlet pipe 33 by the delivery pump 32 and discharged through the second outlet pipe 34 into the fixed frame 15 and the triangular groove 16. The water flows out from the output groove 17 at the bottom of the triangular groove 16. After being guided by the guide cloth 18, the water flows downward along the outer wall of the cable 37, completing the slow-flow cooling operation. This structure reduces the impact of the water flow on the outer wall of the cable 37 during the cooling process by guiding the water flow through the guide cloth 18 to the top of the cable 37, avoiding damage to the outer wall of the cable 37. It also avoids the cable 37 bending and causing creases when transported into the water tank 3. Water flow cooling is more efficient than water mist spraying. At the same time, the water flow after being guided can reduce the impact on the cable 37 while ensuring the flow rate, thus improving the efficiency of use.
