April 20, 2025 – A newly granted utility model patent that promises to revolutionize the feeding technology of color masterbatch machines has recently captured the industry’s attention. The patent titled “A Feeding Device for Color Masterbatch Machines,” applied for by Guangdong Lihong Equipment Technology Co., Ltd. in June 2024, has now been officially authorized.
This patent focuses on the technical field of color masterbatch machine feeding. The disclosed feeding device features an ingenious structure. The feeding hopper is firmly positioned at the top of the color masterbatch machine, seamlessly connecting with its internal cavity, while the top cover provides reliable sealing. Notably, the feeding hopper is equipped with a mixing mechanism inside and a lifting mechanism at the rear that works in tandem with the cover. These innovative designs form a comprehensive feeding system.
According to AsiaMB, in the past, when feeding color masterbatch machines, feeding hoppers often lacked components for mixing raw materials and additives. As a result, users had to manually mix the raw materials and additives in advance, which was a cumbersome process and significantly reduced the convenience of using the feeding hopper. However, this patent by Guangdong Lihong Equipment Technology Co., Ltd. has successfully addressed this long – standing industry pain point. It effectively enhances the practicality and operational efficiency of the feeding hopper, potentially opening up new development opportunities in the field of color masterbatch machine feeding.
