Weighing filling machine is based on programmable intelligent module, industrial control computer and RS485 fieldbus to realize signal acquisition, processing, control and output, which constitutes a cost-effective weighing system. The communication between monitoring computer and management computer is realized by using local area network. IOM4017 module is adopted, D/O conversion is adopted IOM4050 module, and the open-door filling valve is controlled by an IOM4050.
020-34563445Automatic Filling machine is a mechanical and electrical integration of products, using microcomputer control technology, can complete the automatic feeding, weighing, bucket filling, capping and other functions. It consists of a feeding part, a rotor Feeder, a weighing part, a barrel mechanism, a pneumatic lifting device, a belt conveyor, a capping device, an upper frame, a lower frame, a transition bucket, a recovery cover, an electric control cabinet, a nitrogen system and an electrical control system. The feeding device is mainly composed of a three-stroke feeding mechanism and an electromagnetic rotor feeder. The three-stroke feeding mechanism is mainly composed of bucket body, three-stroke cylinder, three-opening curved cutting door, upper flange and upper and lower adjustment structure. This feeding mechanism adopts the self-weight feeding mode, the device structure is simple, the operation is safe and reliable, the commonality is good, the feeding precision is high, the speed is fast. The three-stroke feeding mechanism is located at the top of the upper frame, and the rotor feeder is located at the appropriate position between the three-stroke feeding mechanism and the weighing part. The combined use of the two mechanisms will ensure the feeding accuracy and improve the filling accuracy. The weighing component is mainly composed of weighing bucket body, movable door body, opening and closing cylinder, weighing module and sensor support. The weighing component is under the feeding device and above the transition bucket.
After the feed system starts feeding, the signal is transmitted to the relay that controls the three-stroke cylinder and the rotor feeder. The three-stroke cylinder is initially in a contracted state. When a certain amount of time is quickly added, the three-stroke cylinder begins to extend the first stroke, and the opening of the three-opening arc cutting door decreases by a certain Angle. When the material measurement in the weighing bucket reaches a certain level (85% of the measurement), the three-stroke cylinder extends the second stroke, leaving only the small mouth of the three-degree arc cutting door to feed, and this is actually a slow adding state. When measuring or slowly adding to the expected time, the three-stroke cylinder extends the third stroke, the three-opening arc cutting door is completely closed, and the feeding is stopped. If the three-degree arc cutting door is completely closed but the measurement does not reach the set measurement, the rotor feeder starts, and the small flow rate is slowly fed, so as to further improve the feeding accuracy and ensure the weighing accuracy. When the measurement reaches the theoretical measurement, the three-stroke feeding mechanism and the rotor feeder of the feeding device stop feeding. And the signal is transmitted to the relay that controls the valve cylinder of the weighing device, the valve cylinder on both sides is extended, the valve is opened, and the filling begins. After filling is completed, the filling cylinder shrinks, the filling rocker arm opens, and the filling barrel falls on the belt conveyor. Control the valve cylinder of the weighing device to shrink, the valve to close and wait for the next cycle.
