Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, and in particular to a polymer dynamic vulcanization composite material molding equipment. Background Technology

[0002] Dynamically vulcanized polymer composites are high-performance materials prepared through dynamic vulcanization technology, possessing excellent mechanical properties, heat resistance, and chemical corrosion resistance. In recent years, with the increasing demand for lightweight automobiles and high-performance building materials, dynamically vulcanized composites have been increasingly widely used in industry.

[0003] In existing technologies, the molding of dynamically vulcanized composite materials mainly employs equipment such as twin-screw extruders, internal mixers, and open mixing mills. Twin-screw extruders achieve material mixing and vulcanization through the meshing action of two screws, but their structure is complex and maintenance costs are high. Internal mixers achieve material mixing and vulcanization through the rotation of rotors, but they suffer from high energy consumption and low production efficiency. Open mixing mills achieve material mixing and vulcanization through the relative movement of two rollers, but they suffer from poor product consistency and low automation. Utility Model Content

[0042] Specifically, the high-pressure vulcanizing module 3, through the action of the pressure block 303, can apply high pressure within the vulcanizing chamber 305, effectively promoting the vulcanization reaction and increasing the degree of cross-linking of the polymer material, thereby enhancing the physical properties and durability of the final product. The design of the hydraulic cylinder 302 allows for precise control of the movement of the pressure block 303, ensuring uniform pressure distribution during the vulcanization process, avoiding local overpressure or underpressure, and ensuring consistent vulcanization results. The design of the heating base 304 allows the vulcanizing chamber 305 to be tightly integrated with the heating system, providing a stable temperature environment during the vulcanization process, further promoting the vulcanization reaction and improving production efficiency. The design of the fixed platform 301 makes the installation and disassembly of the high-pressure vulcanizing module 3 more convenient. The design facilitates daily maintenance and repair of the equipment, reducing downtime. The cooling module 4, through the design of the condensate storage tank 401 and the spiral winding tube 404, can quickly cool the material after extrusion, ensuring that the vulcanized product is cured at the appropriate temperature, preventing material deformation or performance degradation due to excessive temperature. The combination of the condensate storage tank 401 and the delivery pump 402 allows the coolant to be recycled, reducing energy consumption and material waste, and improving the economy and environmental friendliness of the equipment. The design of the spiral winding tube 404 allows the coolant to be evenly coated on the outside of the extrusion tube 207, thereby achieving efficient heat exchange, ensuring uniform temperature distribution of the material during the cooling process, and avoiding uneven cooling.

[0043] Reference Figure 1 , Figure 4 A stirring drive module 5 is fixedly connected to the top right side of the top plate 102. The stirring drive module 5 includes a drive motor 501. The bottom of the drive motor 501 is fixedly connected to the top of the top plate 102. A drive shaft 502 is fixedly connected to the drive end of the drive motor 501. A driving bevel gear 503 is fixedly connected to the outer side of the drive shaft 502. A driven bevel gear 504 is fixedly connected to the upper outer side of the outer rotating shaft 203. The outer sides of the driving bevel gear 503 and the outer sides of the driven bevel gear 504 mesh with each other. The top left side of the top plate 102 is fixedly connected to the extrusion drive module 6. The extrusion drive module 6 includes a second drive motor 601. The bottom of the second drive motor 601 is fixedly connected to the top of the top plate 102. The drive end of the second drive motor 601 is fixedly connected to a second drive shaft 602. The outside of the second drive shaft 602 is fixedly connected to a drive pulley 603. The top of the inner rotating shaft 205 is fixedly connected to a driven pulley 604. A connecting belt 605 is coupled between the driven pulley 604 and the drive pulley 603.

[0044] Specifically, drive motor 501 provides powerful performance, efficiently transmitting power to the outer rotating shaft 203 via drive shaft 502 and a bevel gear transmission system. This ensures that the stirring rod 204 can quickly and evenly stir the material, improving the mixing effect. The bevel gear design allows for precise adjustment of the stirring speed as needed, adapting to the stirring requirements of different materials and ensuring optimal stirring results under various working conditions. Fixing drive motor 501 to the top of the top plate 102 saves space and makes the layout of the entire stirring system more compact, facilitating the overall design and installation of the equipment. Drive motor 601 transmits power to the inner rotating shaft 205 via drive shaft 602 and a pulley system, ensuring that the spiral extrusion blades 206 can extrude material at a stable speed, improving extrusion efficiency. The use of the connecting belt 605 reduces impact and vibration in the mechanical transmission. This design makes the extrusion process smoother, reduces equipment wear, and extends service life. By adjusting the speed of drive motor 601, the extrusion speed can be easily adjusted to adapt to the processing requirements of different materials, ensuring product quality and consistency. The design of the mixing drive module 5 and the extrusion drive module 6 enables the mixing and extrusion processes to work efficiently and collaboratively, ensuring the continuity and consistency of materials during mixing and molding. The efficient power transmission and control system of the two drive modules can significantly improve the overall efficiency of the production line, reduce the residence time of materials at each stage, and accelerate the production cycle. The modular design makes the maintenance and repair of each drive system more convenient, reduces the risk of equipment failure, and improves operational safety. Through the control of the drive motor, intelligent monitoring of the mixing and extrusion processes can be achieved, further improving the automation level of the equipment and adapting to the needs of modern production.

[0045] Working principle: First, after the equipment is started, drive motor 501 drives the outer rotating shaft 203 to rotate through drive shaft 502 and bevel gear transmission system, which drives multiple stirring rods 204 to stir inside the stirring extrusion conical tank 201. This process ensures uniform mixing of materials, providing a good material foundation for subsequent extrusion. At the same time, drive motor 601 drives the inner rotating shaft 205 through drive shaft 602 and pulley system, causing the spiral extrusion blades 206 to rotate, thereby extruding the material in the stirring extrusion conical tank 201 along the spiral channel. The material is then sent into the vulcanization chamber 305 through the extrusion pipe 207.

[0046] During the conveying process, the cooling module 4 rapidly cools the extruded product through the condensate storage tank 401 and the spiral winding pipe 404, ensuring that the product solidifies at the appropriate temperature and avoiding material deformation or performance degradation due to excessive temperature. The recycling of the coolant reduces energy consumption and material waste, and improves the economy and environmental friendliness of the equipment.

[0047] After the material enters the vulcanization chamber 305, the hydraulic cylinder 302 applies high pressure through the pressure block 303 to promote the vulcanization reaction. At the same time, the heating base 304 provides stable heating for the vulcanization chamber 305 to ensure the suitability of the vulcanization temperature. The high temperature and high pressure conditions during the vulcanization process help to improve the degree of cross-linking of the polymer material, thereby enhancing the physical properties and durability of the final product.
