Description

Technical Field

[0001] The invention belongs to the technical field of plastic masterbatch production, and in particular relates to plastic masterbatch production equipment. Background Art

[0002] Plastic masterbatch is a material used to color plastic products. It is usually a granular substance with pigments or colorants as the main components. The application range of plastic masterbatch is wide, covering electronic appliances, daily necessities, auto parts, building materials, packaging products and other fields. By adjusting the formula and color of plastic masterbatch, more personalized and innovative plastic products can be made. Its production equipment is a processing machinery equipment that realizes the mixing, extrusion cooling and pelletizing steps of multiple materials. However, during the processing steps, pigments will remain inside the mixing device, so that different colors will be contaminated when injected, affecting the processing needs. During the water-cooling molding process, water stains will remain on the surface after the water is discharged. In this way, when it enters the pelletizing equipment, it is easy to cause the pelletizing equipment to be damaged by moisture when it is scattered during pelletizing, and the pelletizing process is uneven, resulting in larger particles. Plastic masterbatch is not convenient to separate, which is inconvenient for subsequent packaging work. Summary of the invention
