Material mixing control method based on spiral conveying type color master mixing device

Abstract

The invention discloses a material mixing control method based on a spiral conveying type color master mixing device. The spiral conveying type color master mixing device comprises hoppers (1), material conveying mechanisms (2) and a material box (3). The hoppers (1) and the material conveying mechanisms (2) are installed in a one-to-one correspondence mode. The material conveying mechanisms (2) are installed on the material box (3). Feeding inlets corresponding to the material conveying mechanisms (2) are formed in the material box (3). Materials mixed through the color master mixing device are conveyed to an injection molding machine to be subjected to melting injection molding, and thus an injection molding product is obtained. The color master mixing device further comprises an image recognition system. An image of the injection molding product is input and the colors of the image are recognized by the image recognition system, and the conveying speed of the material conveying mechanisms is adjusted according to the comparison result. According to the material mixing control method based on the spiral conveying type color master mixing device, the image recognition technology is introduced, negative feedback is added, the comparison result is used for controlling the material conveying speed of the material conveying mechanisms, and thus products of which the color is consistent with that of an expected standard are obtained.

Description

Technical field [0001] The invention relates to the field of color masterbatch mixers, in particular to a material mixing control method based on a screw conveying type masterbatch mixing device. Background technique [0002] The full name of color masterbatch is called color masterbatch, which is a new type of special colorant for polymer materials, also known as pigment preparation. Color masterbatches are mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. pigment The aggregate made evenly loaded in the resin can be called a pigment concentrate, so its tinting power is higher than the pigment itself. Color masterbatch (multiple colors can be used) and uncolored resin blended during processing can achieve the colored resin or product with the designed pigment concentration. [0003] The mixing of color masterbatches needs to be realized by a masterbatch mixer. Each color masterbatch is equipped with a hopper....
