Single screw Automatic batching machine is a complete set of automatic equipment for dynamic weighing and batching control through electrical control management and visual man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed according to the production requirements. The software adopts the human configuration, according to the process requirements, through the monitoring system and PLC program to load the material to the weighing hopper weight, flow control, so as to achieve accurate measurement and batching.
020-34563445The single-screw automatic batching machine can quickly and accurately complete the quasi-dynamic metering of powder materials, and can simultaneously conduct real-time quality inspection on multiple powders. It adopts a multi-task operating system and communication capabilities, and uses a single-screw extruder with a main motor of 75kW DC, driven by a digital DC speed regulation system. The extrusion volume is adjusted by the communication port on the main station processor of the equipment communicating with the E590 DC drive system via RS422, and the rotational speed of the DC motor (i.e., the rotational speed of the extruder screw) is regulated. After each material is fed in several batches to any one or several feeding positions of the feeding level, it enters the next material feeding process according to the instruction. Each feeding process can be automatically cycled or at any time, the operator can instruct to add single materials in batches or modify the sequence of cyclic feeding. If a certain device malfunctions during normal operation, the PLC can automatically stop the incoming material source devices before this device, cut off the material source, and at the same time delay the operation of the devices after this device for a period of time to ensure that there will be no material blockage during the feeding process. The time of the feeding process can be automatically or manually modified at any time through the upper computer to set parameters.
After the material enters the Feeder from the silo, the weighing signal of the material enters the weighing funnel. The weighing signal is processed by the controller to control the vibrating feeder to discharge at a certain speed. When the measured material reaches the set value, the feeding stops. When it is confirmed through inspection that the feeding bin is at the designated feeding position and there is no material in the bin, the feeding bin is opened according to the operator's instructions or the automatic program, and the material enters the feeding bin. When all the measured materials enter the feeding silo and it is confirmed that the silo door for measured feeding is closed, the next batch of materials is added according to the operator's instructions or the automatic program. At the same time, the walking motor of the feeding silo is started according to the operator's instructions or the automatic program to complete the lifting process. When the feeding silo reaches the designated position, the silo stops, the silo door opens, and the materials are added and poured into the silo. When all the materials in the feeding bin have been poured into the bin, the feeding bin returns to its original position, the valve closes, and the feeding bin returns to the designated bin to start the next batch of feeding. After being processed by the PLC, it serves as a position (displacement) signal to participate in the detection of the batching position, travel correction and control (in the automatic Batching system, the travel switch takes priority).
Design features
The continuous dynamic metering method is adopted for the quantitative metering of solid and liquid powder materials, which can control the fast and slow feeding, improving both accuracy and ensuring production efficiency.
2) By adopting centralized control on the operation console and developing configuration software, it can quickly respond to changes in customer demands. The human-machine interface is friendly. Operators can monitor the working status of the production line in the control room, improving efficiency and the speed of handling abnormal situations.
3) The centralized installation of weighing instruments makes communication with monitoring software and PLCS more convenient, safe and reliable.
4) The production and management software is powerful and can complete various production formula management, process control, abnormal alarm, as well as the collection, storage, report analysis and printing of production data.
5) It is convenient to upgrade and expand. If users need to expand the existing system, they only need to introduce the newly installed sensor leads and valve control lines into the control room and add the corresponding functional modules on the software interface. It is simple and fast.
6) It is equipped with pressure and liquid level detection inside the warehouse. Liquid level gauges and pressure sensors can be installed in the raw material warehouse. The centralized control center can monitor the liquid level, pressure, etc. in real time to prevent accidents.
