1results about How to "Stable feeding speed" patented technology

This invention belongs to the field of plastic processing and packaging technology, and specifically to a quantitative packaging method for plastic granules for sale. The method includes the following steps: raw material pretreatment, precision feeding, dynamic weighing, automatic bagging, vacuum heat sealing, online quality inspection, intelligent traceability code printing and labeling, automatic palletizing, and finished product warehousing. In the pretreatment stage, the invention utilizes a fully enclosed chamber with a temperature of 18-22℃ and humidity ≤40%RH, combined with a vibrating screen and an ion wind electrostatic eliminator. This achieves a plastic granule moisture content ≤0.08%, a surface dust and agglomerate removal rate ≥99.5%, and a dust concentration ≤0.5mg / m³. This eliminates the problems of electrostatic agglomeration and dust dispersion in existing technologies, ensuring smooth subsequent feeding and accurate weighing. It also significantly improves the working environment, meeting environmental protection and safety production requirements. The invention employs a dual-sensor electronic scale to achieve dual-stage control of coarse and fine feeding, improving accuracy by more than 20 times compared to existing technologies. This meets the stringent requirements for net / gross weight for sales and significantly shortens the production cycle.
