Nowadays, EPS foam processing companies have achieved mass production. During the production process, the pre-expander machine and the shape molding machine have been automated, but the silo connecting the two parts is still manually operated. For relatively large foam processing enterprises, there are generally dozens of silos. During the production process, the input and output of these silos need to be managed and switched manually. If the switching is not timely or the switching is wrong, it will easily lead to the use of the material equipment shuts down or produces products that do not meet the requirements. This manual method is not only labor-intensive, but also inefficient and error-prone.
The EPS silo management control system can realize the timely, accurate and automatic switching of the silo feeding and discharging process, including EPS pre-expander machine, blowing pipeline, standard silo, suction pipeline, EPS shape molding machine, silo three-way valve , The silo level sensor and silo control, the discharge port of the EPS pre-expander machine is connected with the blowing pipeline, the standard silo is connected with the suction pipeline through the discharge valve, and the suction pipeline is connected with the EPS shape molding machine; The standard silo is connected with the blowing pipeline through the three-way valve of the silo; the silo level sensors are respectively installed on the side walls of the upper and lower parts of the standard silo; the silo control cabinet is equipped with a PLC controller and a solenoid valve; The valve of the three-way valve of the silo is controlled by the cylinder, the air intake pipe of the cylinder is connected with the solenoid valve through the PU pipe, and the solenoid valve is controlled by the PLC controller. The beneficial effect of the utility model is to automate the conveying process of the EPS silo raw materials, save manpower, and improve the timeliness and accuracy of silo switching during the raw material conveying process.
