Batching scales through a variety of materials were automatically quantitative weighing to complete a dosage of automatic batching equipment, powdery materials for the control of feeding, dynamic measurement, continuous delivery of production metering equipment. Pre-given mass ratio, the equalizer for the weighing of several substances in the dosage measurement. Divided into single tube single layer and double tube double layer, single tube single layer together with the completion of measurement and transportation, double tube double layer structure, the upper layer to complete the flow stabilization and transportation, the base layer to complete the measurement and transportation, the effect of flow stabilization is better and save space.
020-34563445Batching scale is divided into material storage, batching, Measuring system and electrical control system, in which the control system has two operation modes, automatic and manual. The double screw structure conveyor is used, and the double screw structure is installed in an "8" type body, with the screw rotating, the material in the body is subjected to a forward thrust forward, and at the same time, in the process, the material is squeezed, which makes a certain sealing effect in the body. At the same time, during the process, the material is squeezed, which makes the body produce a certain sealing effect, followed by a certain sealing pressure, so this conveying structure has a very good effect on conveying powders, pastes, cakes and other moisture-containing materials.
The Dosage system mainly includes signal input and conditioning module, data acquisition module, dosage control and calculation processing module, input and display module, motor drive module and discharge valve drive module. The load cell converts the weighing signal into a voltage signal, which is amplified and adjusted by the transmitter and processed by the data acquisition card for A/D conversion, and the generated digital quantities are processed in the dosage controller, and these quantities can be shown in the display, and also can be fed back to adjust the coordinated actions of the motor, the pusher, and the unloading valve. Preset quantities are entered into the controller from the keyboard.
Vacuum loading device in the material feeding device design chose the spiral feeding system, the whole device of the feeding, feeding system sealed connection, good control of dust flying. Reference to the previous coarse and fine weighing method, and improve it, try to produce accurate weighing of the dual-core working mode: that is, after the end of the coarse weighing process, by pushing the device will weighing cups pushed to the fine weighing unit, the coarse weighing process does not need to wait, directly into the next weighing cycle. Coarse weighing and fine weighing two processes at the same time, to avoid the past due to the fine weighing process affects the weighing efficiency of the entire device shortcomings. Greatly improve the weighing efficiency and practicality of the equipment.
Through the signal input and conditioning module, data acquisition module, dosage control and calculation processing module, input and display module, motor drive module and unloading valve drive module of the control system, it realizes good man-machine interaction function. It can simultaneously control multiple scales, many different materials or control output operation is intuitive, clear, automatic recovery function; powerful report function, can record and store all kinds of data in large quantities and tabulate and print; good reliability; powerful alarm prompting function can minimize the scrap rate; equipped with on-line automatic monitoring software to monitor the important information of the production at any time through real-time on-line monitor.
