Description

Technical Field

[0001] This utility model relates to the field of alloy material preparation technology, and in particular to a mixing device for preparing PC / ABS alloy materials. Background Technology

[0002] PC / ABS alloy material is a plastic alloy material made by mixing polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS) in a certain proportion and through a special processing technology. One step in the preparation of these materials is to mix them, and a mixing device is used when mixing them.

[0003] To address this, patent specification CN218901524U discloses a powder mixing device, including a table, a mixing barrel fixedly connected to the top of the table, a motor fixedly connected to the top of the mixing barrel, and a stirring shaft fixedly connected to the output end of the motor through the top of the mixing barrel. Several mixing rods are fixedly connected to the outside of the stirring shaft, and a set of connecting rods is fixedly connected to both sides of the stirring shaft. In this invention, starting the motor drives the mixing rods to mix the powder in the mixing barrel, completing the powder mixing operation. During the rotation of the stirring shaft, the connecting rods rotate synchronously, causing a scraper to clean the inner wall of the mixing barrel, effectively removing the powder adhering to the inner wall. This ensures the cleanliness of the inner wall of the mixing barrel after powder mixing while avoiding powder waste, making it worthy of widespread promotion.

[0004] While the aforementioned technology allows the connecting rod to rotate, thereby driving the scraper to clean the inner wall of the mixing tank and effectively remove the powder adhering to the inner wall, ensuring the cleanliness of the inner wall of the mixing tank after powder mixing and avoiding powder waste, uneven mixing can easily occur when mixing raw materials. Therefore, a mixing device for PC / ABS alloy material preparation is needed to solve the above problems. Utility Model Content

[0011] Preferably, one end of the bolt passes through both ends of the screening rack and is inserted into the interior of the top of the holding box, and the bolt and the top of the holding box form a threaded connection.

[0012] Preferably, the bolts are provided in two sets, and the two sets of bolts are symmetrically distributed at both ends of the screening frame.

[0013] Preferably, there are two sets of collection boxes, which are symmetrically distributed on both sides of the holding box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating a mixing structure, when mixing PC or ABS alloy powder, the rotating stirring rod can initially stir the PC or ABS alloy raw materials. Furthermore, the rotating blades drive the raw materials upward at a certain speed, creating a tumbling effect. This, combined with the stirring of the stirring rod, achieves uniform distribution and mixing of the raw materials, thus improving the mixing effect of PC or ABS alloy raw materials.

[0016] By incorporating a screening structure, the screening rack can be used to screen the mixed raw materials, removing impurities. The screened materials fall into the holding box. Due to the sloping sides of the screening rack, the screened impurities can fall directly into the collection box, achieving rapid screening and collection of impurities, making the screening of mixed raw materials more convenient.
