The double screw Weighing system is composed of large screw conveyor, small screw conveyor, mixing mechanism, material Electronic scale, frame and silo. After the equipment is started, the mixing mechanism starts to operate to prevent the material in the silo from arching and affecting the continuous transmission of the material. The screw conveyor consists of a stepper motor, a reducer and a screw shaft with a screw blade. The spiral axis rotates so that the powder material moves relative to the spiral surface, and the material is subjected to the friction of the material groove or the conveying pipe wall and does not rotate with the spiral blade, thus pushing the material along the axial direction to achieve the conveying of the material. At the beginning of material delivery, large and small screw conveyors work at the same time, and the work of large screw conveyors can improve the efficiency of material delivery. When the weight of the material in the tray reaches a preset weight value (the preset weight value is generally set to about 95% of the final weight value of the material), the weighing module sends a signal to the control system, and the control system controls the stepping motor of the large screw conveyor to stop working. At this time, only the small screw conveyor continues to work to achieve the purpose of accurate feeding.

Automatic control of various equipment such as package conveying control, weighing batching, material mixing and mixing control, packaging and filling in the centralized weighing system, involving powder, granular, block, sheet and other materials; Combined with the characteristics of the material, reasonable selection of single material ingredients, multi-material sequential accumulation, weight reduction ingredients, weight loss balance ingredients and other measurement methods. Batching weighing instrument provides a complete control scheme, integrating touch display, production management, weighing module collection and processing, feeding and unloading, output and other functions, one instrument can meet the user control production requirements, high integration; The batching weighing control module provides all functions except touch display and production management, and completes the control with man-machine interface; The weight transmission mainly collects the weight signal of the packaging scale, and transmits the output to the PLC after internal filtering processing, and the PLC completes the other control parts.

The feeding system is divided into material storage, batching, weighing system and electrical control system, of which the control system has automatic and manual two modes of operation, simple operation, flexible control, can meet the various needs of production, with the highest practicality. Can be adapted to powder, particles, liquid and other material ingredients, stirring control. According to your requirements, we can tailor a set of stable, in line with your company's control requirements of industrial batching control system, batching software system solutions.
