Description

Raw material processing mechanism for BMC bulk molding compound production Technical Field The utility model relates to the technical field of BMC material processing, in particular to a raw material processing mechanism for BMC bulk molding compound production. Background The BMC bulk molding compound is used as a thermosetting composite material, and the production raw materials mainly comprise unsaturated polyester resin, calcium carbonate filler, chopped glass fiber and various additives. The calcium carbonate filler and the chopped glass fibers are subjected to sufficient drying treatment before mixing so as to avoid abnormal resin curing caused by moisture residue or air hole defects in the finished product. In the traditional production process, the raw material drying and mixing procedures are generally carried out step by step, namely, the drying equipment and the mixing equipment are independently operated, so that the material transferring link is complicated, the energy consumption is increased, and the dried filler and fiber are easy to agglomerate again due to electrostatic force or humidity change, so that the subsequent dispersion uniformity with the resin slurry is affected. In addition, the existing mixing device adopts a single stirring shaft structure, so that high-efficiency shearing is difficult to form for a mixed system of high-viscosity resin and powdery filler, and mixing dead angles are easy to occur. Some devices try to integrate the drying function, but the material falls uncontrollably, and the dried material is easy to be intensively distributed in a certain area in the resin slurry after being intensively fed into the resin slurry, and needs to be stirred for a long time to be uniformly mixed, so that the mixing treatment efficiency of the raw materials is low.
