Description

Technical Field

[0001] The utility model relates to the technical field of ETFE film raw material mixing, in particular to a raw material mixing device for producing and processing ETFE film. Background Art

[0002] ETFE film is a plastic film produced by a casting method. The ETFE material and masterbatch must be mixed uniformly beforehand. The mixed raw materials are then plasticized and melted in an extruder. The mixed materials are then extruded through a forming die and cast in a sheet-like form onto the surface of a steadily rotating cooling roller. The film is cooled and shaped on the cooling roller, and then hauled and trimmed before being rolled up. Existing ETFE materials and masterbatches (such as UV-resistant masterbatches) are mixed unevenly, which affects the performance of the raw materials after they are plasticized and melted in the extruder, thus affecting the quality of the product.

[0003] The China Patent Network discloses a raw material mixing device for ETFE film production and processing, labeled "CN218557912U." The device comprises a mixing body mounted on a base and a mixing extruder mounted on its side. The mixing body is provided with a first mixing chamber, a second mixing chamber, and an equipment connection chamber, arranged from top to bottom. The bottom of the first mixing chamber is connected to the second mixing chamber via a material drop channel. A first mixing screw is mounted in the first mixing chamber, and a second mixing screw is mounted in the second mixing chamber. An ETFE pellet feed hopper connected to the first mixing chamber is mounted on the top of the mixing body, along with a masterbatch feed hopper on its left end. This improves the mixing effect, but the raw materials may contain moisture during use. Failure to dry the raw materials will result in a reduced mixing effect and quality. Utility Model Content
