Description

Technical field

[0001] The invention relates to the processing field of polyurethane composite materials for automobile roofs, in particular to a mixing machine for producing polyurethane composite materials for automobile roofs. Background technique

[0002] Polyurethane composite materials for automobile roofs often need to use a mixer during the preparation process. The mixer realizes the stirring and mixing of the raw materials. The particle size of the solid raw materials will directly affect the quality of the prepared products. Moisture may occur during the storage process. Moisture of the raw materials may affect the quality of the prepared products. When the raw materials of the mixer are introduced, the position of the feed inlet is set, so that the imported raw materials are too concentrated and piled up, which will affect the raw materials. The mixing and mixing of the machine body will inevitably adhere to the raw material particles on the inner end wall after workin...
