corresponding time arrives, it will be triggered respectively: the next tank of aggregate batching, feeding of cement, water and chemicals, lowering of hopper, start of mixing timer. When the cement feeding time arrives, close the unloading butterfly valve and trigger the next cement batching. When the feeding time of water and reagent arrives, close the solenoid valve, stop the booster pump and trigger the next filling and reagent batching. When the hopper drops to the lower limit, it will stop automatically and wait for the feeding of aggregate belt.
3. Mixing and unloading concrete: when the mixing time arrives, open the concrete unloading door and start the unloading timer. When the time arrives, it will be closed automatically, and the output data will be counted at the same time.
During operation: (vehicle capacity) the last tank of concrete batching is completed, the system is closed, the batching trigger is triggered, and batching is no longer required. After the unloading of the last tank of concrete is completed, the system disconnects the automatic operation contact and returns to the standby state.
Conclusion:
The system has the advantages of simple structure and convenient operation and maintenance. It is suitable for small concrete mixing plants on the construction site. However, it still has shortcomings. With the development of modern science and technology, electronic belt scale and liquid flowmeter have also been widely used. The introduction of new technology to further simplify the system structure, mechanical structure and metal structure is a new idea to improve the performance of equipment. After the machine is started, count every time a sealing and cutting action is completed. After the power is turned on, the counter is automatically cleared. 7) Stop positioning function: when the machine is stopped in any state, the heat seal body is in the open position to avoid scalding the packaging materials. 8) Automatic shutdown and alarm function: in case of paper break, no paper and bag jam, it will automatically stop and alarm. That is, when the packaging material breaks or the packaging material is used up (see Fig. 8 for paper breaking detection) and the packaging bag accumulates above the cutter (see Fig. 10 for bag jamming detection), the machine will automatically stop and give an alarm to prompt the operator to deal with it. Carefully understand the input and output equipment, check the location and name of the sensor and the relationship with the output equipment. 3) understand the safety protection measures and fault alarm in the control process. 4) prepare the program in line with the control process. 5) commissioning program. 5 Use logo! 6. No design circuit diagram / wiring diagram LOGO! Control program development 1) control program of main motor
The bag pulling motor of the particle packaging machine uses a stepping motor driver to control the bag pulling time and length. In the logo, there is no corresponding function block, so in the program I designed, the control of bag pulling motor needs to be improved. 2) Other control logos of this model of particle packaging machine can be basically realized. However, due to the large number of digital signal inputs required in the control process, more expansion blocks are required. This change will reduce the cost. 3) The particle packaging machine has strict requirements on the heating temperature of heat seal. Considering that the cost will be increased if the input quantity is continuously increased, and this model of packaging machine can be well realized through simple control, the input of analog quantity is not considered in this project.
