Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch production, in particular to a multi-component proportioning masterbatch mixing device. Background Art

[0002] Masterbatch is a plastic color ingredient with high color concentration and good dispersion. It is widely used in the plastic product manufacturing industry to provide the desired color. Masterbatch is mixed with colorless or naturally colored plastic raw materials to give the final product the desired color. With the growing market demand for precise color matching, the role of masterbatch mixing devices has become particularly important. This device is responsible for accurately mixing different masterbatches to ensure the consistency and accuracy of the color of plastic products. However, traditional masterbatch mixing methods often fail to meet the requirements of high precision and high uniformity mixing, especially when dealing with multi-component masterbatches.

[0003] The patent with the publication number CN210336526U discloses a multi-component masterbatch metering and mixing device, including a metering bin, a screw feeding device, a feeding valve, a weighing device, a frame, a silo and an electrical control module; the feeding valve is connected to the metering bin, the metering bin is connected to the screw feeding device, the screw feeding device is connected to the silo, the weighing device is connected to the screw feeding device and the metering bin; the electrical control module is electrically connected to the feeding valve, the screw feeding device and the weighing device; the frame is used to connect the metering bin, the screw feeding device, the feeding valve, the weighing device, the silo and the electrical control module to form a unit body. The utility model adopts a compact structural feature, is simple and compact, and can well meet the process requirements.

[0004] The above-mentioned prior art shows that multiple materials are metered and introduced into the silo through multiple units, and a static mixing structure is configured in the silo, including a multi-stage mixing guide vane. This arrangement allows the granular materials entering the silo through the screw barrel to be mixed in multiple stages. Although the system can achieve a certain degree of mixing of multiple materials, the static mixing structure in the silo often takes a long time to achieve full mixing of the materials due to the lack of effective pre-dispersion treatment when mixing multiple materials. In view of this, we propose a multi-group colorimetric masterbatch mixing device. Utility Model Content
