Background The plastic coloring and particle additive mixing equipment is widely applied to the fields of injection molding, extrusion, film blowing, 3D printing consumable production and the like. In such processes, the colored master batch or particulate additive is typically mixed with the substrate particles in a predetermined ratio before entering the subsequent forming equipment. Since the compounding results directly affect the color consistency, molding stability and batch quality of the product, how to maintain the stability of the compounding process under continuous feeding conditions has become a key issue in the design of related equipment. Most of the existing color masterbatch mixing equipment can complete proportioning supply of different particle materials, but in actual operation, the movement state, falling rhythm and collecting state of the particle materials often have differences after the particle materials enter the equipment from different positions. Especially under continuous processing scene, the condition that different materials are easy to be gathered locally, distributed unevenly or concentration fluctuates in stages before entering the mixing area and after entering the mixing area, so that the materials are close to a set value in overall proportion, but still difficult to keep a stable and consistent mixing state in local space. Therefore, in the prior art, under the conditions of continuous conveying and continuous discharging, synchronous stabilization of ratio control and mixing uniformity is difficult to achieve. When the equipment only pays attention to the feeding proportion and lacks effective adaptation to the mixing process after material collection, the output material discreteness is easily increased, and the color uniformity and the product consistency of subsequent formed products are further affected.
