A color masterbatch mixing device and a plastic bottle injection molding process

Abstract

This application relates to the technical field of injection molding of plastic products, and relates to a color masterbatch mixing device and a plastic bottle injection molding process, which mainly relates to a color masterbatch mixing device, including a mixing box, which is connected with a main hopper and a color masterbatch hopper. The discharge end of the mixing box is connected with a mixing device, and the mixing device includes a mixing box connected to the mixing box, a mixing barrel arranged in the mixing box, and a mixing barrel that is pierced and fixedly connected to the central axis of the mixing barrel. The mixing shaft at the place, the mixing shaft is horizontally rotatably connected in the mixing box, and the circumferential side wall of the mixing tube has several inlet and outlet passages communicating with the inner cavity of the mixing tube. The application has the following effects: the mixed materials will be mixed in the cylinder, and finally fall from the inlet and outlet passages under the action of gravity, and the mixed materials can increase the degree of confusion and improve the mixing effect during the continuous turning process.

Description

technical field [0001] This application relates to the technical field of injection molding of plastic products, in particular to a masterbatch mixing device and a plastic bottle injection molding process. Background technique [0002] In the process of plastic processing and injection molding, products of different colors need to be matched with color masterbatches of different colors, and the weight of the main material and the color masterbatch will obtain different color depths under different weight ratios, so the color masterbatch has become an injection molding machine. An indispensable equipment in production, through the color masterbatch machine, the color masterbatch and main ingredients can be batched and mixed according to the weight specified in the process formula. [0003] Existing masterbatch mixers, such as the Chinese utility model patent with the authorized announcement number CN205871038U, disclose a screw type masterbatch mixer, including a mounting bas...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when one side of the color masterbatch enters, the result of mixing will be that the main material and the color masterbatch will be more clearly separated, resulting in a decrease in the degree of color mixing during the melting process and a uniform color of the product Poor degree
