Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymer blending technology, and more specifically to an integrated automatic batching and mixing PC / ABS alloy production device. Background Technology
[0002] PC / ABS alloys combine the high impact strength and heat resistance of polycarbonate (PC) with the good processability and surface gloss of acrylonitrile-butadiene-styrene copolymer (ABS), making them widely used in various industries. This material is particularly suitable for applications in the automotive, electronics, and home appliance sectors because it offers good processability while maintaining high strength and heat resistance. Furthermore, the addition of fillers such as glass fibers or mineral fillers can further enhance the material's mechanical properties, dimensional stability, and thermal stability, making it even more outstanding in specific applications.
[0003] The traditional production process of PC / ABS alloys includes several key steps: First, raw material handling, which typically involves drying and premixing to ensure that the raw materials are free of moisture and uniformly mixed; next is the compounding process, which uses a twin-screw extruder or other similar equipment to thoroughly mix and melt-plasticize PC, ABS and their fillers; molding processes commonly include injection molding and extrusion molding, used to manufacture the final product; and finally, post-processing steps, including cooling, cutting and packaging, to complete the entire production process.
[0004] While traditional production processes meet production demands to some extent, numerous problems remain. First, insufficient automation means many steps still require manual intervention, such as raw material addition and equipment adjustment. This not only reduces production efficiency but also increases the risk of operational errors. Second, uneven mixing and significant fluctuations in process parameters make it difficult to guarantee consistent product quality, impacting the performance of the final product. Furthermore, existing production lines suffer from poor adaptability and long changeover times, increasing downtime and costs. These issues collectively hinder the efficiency and sustainable development of PC / ABS alloy production.
[0005] Therefore, providing an integrated automated batching and mixing PC / ABS alloy production device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] See appendix Figure 1 This utility model discloses an integrated automatic batching and mixing PC / ABS alloy production device, comprising:
[0041] Automatic weighing device 1, which includes an automatic weighing unit 11 for automatically weighing PC raw materials, ABS raw materials and auxiliary materials respectively;
[0042] High-speed mixing equipment 2 is located at the post station of multiple automatic weighing units 11 and mixes the materials weighed by the multiple automatic weighing units 11.
[0043] The twin-screw extruder 3 is located at the rear station of the high-speed mixing equipment 2. A single-screw conveyor 6 is provided between the inlet of the twin-screw extruder 3 and the outlet of the high-speed mixing equipment 2.
[0044] Cooling and drying equipment 4 is located at the rear station of the twin-screw extruder 3 and is used to cool the mixture extruded by the twin-screw extruder 3.
[0045] Granulator 5 is located at the rear station of cooling and drying equipment 4 and is used to granulate the cooled and dried mixture.
[0046] To further optimize the above technical solution, the automatic weighing unit 11 includes a material tank 111, an automatic weighing machine 112, and a conveying pipeline 113; the inlet of the automatic weighing machine 112 is connected to the outlet of the material tank 111, and the conveying pipeline 113 is connected to the outlet of the automatic weighing machine 112.
[0047] To further optimize the above technical solution, the automatic weighing machine 112 is electrically connected to a controller 12 and a power distribution box 13.
[0048] To further optimize the above technical solution, an ultrasonic oscillator 14 is installed on the conveying pipeline 113. The ultrasonic oscillator 14 is used to shake off the material, reduce the adhesion of the material to the pipe wall, and ensure precise control of the material.
[0049] Meanwhile, the use of high-speed mixing equipment 2 enables material premixing, ensuring thorough and uniform mixing of auxiliary materials and raw materials. This reduces the pressure required for uniform mixing during subsequent twin-screw extrusion, achieving a more even distribution of auxiliary materials and minimizing fluctuations in key process parameters such as temperature and pressure during mixing, thus ensuring product quality stability. Furthermore, preheating of the raw materials can be achieved by heating the connecting pipe, reducing the temperature difference between the raw materials and the processing temperature, further minimizing fluctuations in key processing parameters and contributing to overall product quality stability.
[0050] To further optimize the above technical solution, the automatic weighing device 1 also includes a funnel mixing chamber 15, the inlet of which is connected to the outlet of multiple conveying pipelines 113, and the outlet of which is connected to the inlet of the high-speed mixing device 2.
[0051] To further optimize the above technical solution, the cooling and drying equipment 4 includes a cooling tank 41 and an air cooler 42 arranged sequentially. The cooling tank 41 can be air-cooled or water-cooled to achieve temperature control of the extruded material.
[0052] To further optimize the above technical solution, the number of cooling tanks 41 is multiple. By combining multiple cooling tanks 41, a gradient reduction in cooling temperature can be achieved, thereby controlling the quality of the PC / ABS alloy.
[0053] To further optimize the above technical solution, the high-speed mixing equipment 2 and the twin-screw extruder 3 are connected by a hose clamp.
[0054] To further optimize the above technical solution, platform ladders are installed around both the automatic weighing equipment 1 and the high-speed mixing equipment 2.
[0055] The automatic weighing machine 112, high-speed mixing equipment 2, twin-screw extruder 3, cooling tank 41, air cooler 42 and granulator 5 mentioned in this embodiment can all be conventional equipment in the prior art. The focus of this utility model is on the integration of the overall equipment and the production mode. The specific equipment structure will not be described in detail.
[0056] The production method in this embodiment is as follows:
[0057] Raw materials PC, ABS, and auxiliary materials are added to their respective material tanks 111. The raw materials are automatically weighed by multiple automatic weighing machines 112 to adjust the mass ratio of the raw materials. The materials are then fed into a high-speed mixing device 2 through a conveying pipeline 113 equipped with an ultrasonic oscillator 14. The PC / ABS alloy material is then horizontally conveyed into a twin-screw extruder 3 via a reverse single-screw conveyor 6. After processing under the set time and temperature conditions, the high-temperature PC / ABS alloy passes through a temperature-controlled cooling tank 41. After cooling, it enters an air cooler 42 and is dried by air before entering a granulator 5 for granulation to obtain PC / ABS alloy granules.
