Huaruida Packaging Obtains Patent Related to Film Hot-Melt Device: BOPP Film Raw Material Mixing and Hot Melting Enhances Material Exchange Uniformity
January 7 news: Information from the China National Intellectual Property Administration shows that Huaruida Packaging Materials Co., Ltd. has applied for a patent titled "A BOPP Film Raw Material Mixing and Hot-Melt Device", with authorization announcement number CN121043297B and authorization announcement date January 6, 2026. The application publication number is CN121043297A, the application number is CN202511587453.3, the application publication date is January 6, 2026, the application date is November 3, 2025, the inventors are Pan Xiaorong, Zhang Cunwen, Li Chengsheng and Pan Junpeng, the patent agency is Wenzhou Renli Intellectual Property Agency (General Partnership), the patent agent is Bian Guangwei, and the classification numbers are B29B13/02 and B29K23/00.
The patent abstract shows that the invention relates to the technical field of plastic processing equipment, and particularly relates to a BOPP film raw material mixing and hot-melt device, comprising a heating kettle, an auger spiral ring, a first drive assembly, a fixed cylinder and a movable cylinder. A hot-melt chamber is provided in the heating kettle, the axis of the hot-melt chamber is vertical, the auger spiral ring is rotatably arranged in the hot-melt chamber, and the axis of the auger spiral ring coincides with the axis of the hot-melt chamber. In the present invention, an auger spiral ring is provided; since the rotation directions of two adjacent auger spiral rings are opposite, under the rotating action of the auger spiral rings, the material also circulates along the radial direction of the hot-melt chamber, increasing the material exchange uniformity in the radial direction of the hot-melt chamber. In addition, under the flow-guiding action of the auger spiral rings, the material in the hot-melt chamber also converges at the junction of two adjacent auger spiral rings, further increasing the material exchange uniformity.
Tianyancha data shows that Huaruida Packaging Materials Co., Ltd. was established on January 12, 1970, its legal representative is Pan Xiaohua, its industry is printing and reproduction of recording media, its enterprise size is medium, its registered capital is RMB 102.048 million, and its paid-in capital is RMB 102.048 million. Its registered address is No. 359 Chengnan Avenue, Ruian Economic Development Zone, Ruian City, Wenzhou City, Zhejiang Province. Huaruida Packaging Materials Co., Ltd. has invested in 0 companies externally, participated in 9 bidding projects, and in terms of property information has 2 trademark records and 54 patent records, and holds 10 administrative licenses.
