TECHNICAL FIELD

[0002] In cover plate glass production, the material side is the most important influencing factor on glass quality. Cover plate glass, as a kind of special glass, has very high precision requirements for the material side, so the weight precision of different raw materials in raw material mixing is extremely high. In raw material mixing, generally, a spiral conveying mechanism is used to convey raw materials from the stock bin to the electronic scale, and after the weighing of different material sides is completed, the raw materials are mixed to become glass raw materials. Since the electronic scale has very high weighing precision, how to ensure the uniformity of the spiral feeding and the weight after meeting the standard so that the raw materials do not enter the electronic scale any more becomes a crucial factor to ensure the weighing precision.
[0003] The cover plate glass mixed material is composed of more than ten kinds of raw materials. Before raw material mixing, different raw material bins are put in, and the spiral conveying mechanism installed at the bottom of the bin conveys each raw material to the corresponding electronic scale for weighing. After weighing, the raw materials are mixed in the mixer and packed to become qualified raw materials. Since some raw materials are prone to moisture and clumping, and some raw materials are clumped in the bin, if clumped raw materials enter the electronic scale at the end of the conveying process, it is likely to cause the weight of the raw materials to exceed the limit value; or after the raw material conveying is completed, due to factors such as vibration, raw materials continue to fall from the front end of the spiral conveyor, which will cause inaccurate weighing of the raw materials, affect the precision of the raw materials, and further affect the proportion of the mixed material, resulting in suboptimal glass quality.
