According to information from the National Intellectual Property Administration, Sanmen Zhenhe Technology Co., Ltd. has obtained a patent titled "A Feeding Device for Color Masterbatch of Degradable Materials," with authorization announcement number CN 222645087 U, and an application date of May 2024.

The patent abstract describes a feeding device for color masterbatch in degradable materials, falling under the category of mechanical equipment. It addresses the issue of traditional color masterbatch addition and transportation methods being largely manual, which not only reduces efficiency but also makes it difficult to ensure the accuracy and uniformity of color masterbatch addition, ultimately affecting the quality and appearance of the products. The color masterbatch feeding device for degradable materials comprises a body and a control box mounted on the body, with a control unit inside the control box. The body includes a frame, on which a conveyor belt for transporting the color masterbatch is mounted. The conveyor belt features several storage compartments for holding the color masterbatch, an outlet box for outputting the color masterbatch, connected to the body via several fixed supports. The outlet box has several outlet openings at its bottom and includes a metering device inside for precisely measuring the color masterbatch as it is conveyed. This utility model ensures the accuracy and uniformity of color masterbatch addition, resulting in improved product quality.
