Description

Technical Field

[0001] The invention relates to the technical field of production of modified polypropylene resin, in particular to a special production system of modified polypropylene resin. Background Art

[0002] Modified polypropylene resin is a thermoplastic resin made by polymerizing propylene. Its properties are enhanced and optimized through modification, resulting in a variety of excellent properties, including high strength and stiffness, excellent heat resistance, chemical resistance, weather resistance, and processability. It can be manufactured into products of various shapes and sizes through processes such as blow molding, injection molding, and extrusion. Therefore, it is widely used in injection molding, blow molding, and extrusion molding. Modified polypropylene resin has a wide range of applications, including the production of various types of daily necessities, food packaging, medical devices, automotive parts, and household items, as well as in the production of building materials. Its excellent mechanical properties and heat resistance make it important in high-end applications such as automotive parts, electronic equipment, and solar panels.

[0003] The production of existing modified polypropylene resin requires polypropylene resin and necessary modifying additives, such as fillers, stabilizers and compatibilizers. These materials should be stored in a designated area and accurately measured and weighed according to the required formula. The polypropylene resin and additives are then mixed and stirred using a mixer or extruder. The polypropylene resin will be melted and then the additives will be gradually added. The mixture will then be stirred or kneaded to ensure that the additives are evenly distributed in the resin. In this process, since the polypropylene resin is mixed with various additives, including dispersants, although the mixing process will try to ensure the uniform distribution of the additives, due to the large-scale preparation of modified polypropylene resin, when a large amount of polypropylene resin is mixed with the additives, the polypropylene resin still has a large viscosity after melting. Although the mixing time and speed are increased, a small amount of dispersant may still not be completely evenly distributed, thereby leaving a small amount of dispersant in the final product, which may also cause certain pollution to the environment. For this reason, we propose a dedicated production system for modified polypropylene resin. Summary of the Invention

The limit gears (413) can support, rotationally limit, and rotationally drive the rotating assembly (44); A cover plate (414) mounted on the top of the mounting cylinder (411); The injection assembly (42) comprises: A bracket (421) mounted on the top of the cover plate (414); An injection cylinder (422) is installed inside the bracket (421), and various additives can be injected into the injection cylinder (422); The injection valve tube (423) is connected to the bottom of the injection cylinder (422), and the bottom of the injection valve tube (423) is in contact with the top of the rotating assembly (44).

10. A special production system for modified polypropylene resin according to claim 9, characterized in that: The rotating assembly (44) comprises: The rotating disk (441) is provided with a limiting ring (442) on the top thereof, and the limiting ring (442) is rotatably connected to the inside of the groove at the bottom of the cover plate (414), and the rotating disk (441) can be suspended and rotationally limited by the limiting ring (442); The second tooth groove (443) is arranged around the outer wall of the rotating disk (441), and the second tooth groove (443) is meshed and connected with the limit gear (413). The limit gear (413) cooperates with the second tooth groove (443) to clamp the rotating disk (441). At the same time, the rotation of the limit gear (413) can drive the rotating disk (441) to rotate; The injection groove (444) is arranged on the top of the rotating disk (441), and when the rotating disk (441) rotates, the injection valve tube (423) can rotate to the top of the injection groove (444) to make the additive fall; A metering cannula (445) is installed at the bottom of the rotating disk (441) and is connected to the injection groove (444). The falling of the additive can be guided through the metering cannula (445); The plug (446) is installed at the bottom of the metering plug (445), and the plug (446) can be inserted into the interior of the polymerized and separated polypropylene resin by driving the telescopic rod (123), and the additive can be directly injected into the interior of the polypropylene resin through the plug (446), and the polypropylene resin can be stirred and mixed through the metering plug (445) and the plug (446); A sealing groove (447) provided on the outer wall of the metering cannula (445); The metering disk (448) is slidably connected to the inside of the sealing groove (447), and the metering disk (448) is slidably connected to the inside of the metering insert (445), and the metering disk (448) is composed of a pressure sensor and a rotary valve, which can block and bear the falling additives and dispense a fixed amount of additives; The sealing toughness strip (449) has one end connected to the top of the metering disk (448) and the other end connected to the top of the sealing groove (447), and the two ends of the sealing toughness strip (449) are slidably connected to the two ends of the inner wall of the sealing groove (447). The sealing toughness strip (449) can block the falling additives and prevent the additives from penetrating the sealing groove (447) into the surface of the polypropylene resin, and can also perform toughness stretching on the load-bearing downward sliding of the metering disk (448).
