commonly used plastic bag packaging machines include vertical packaging machines and horizontal packaging machines. the main working principle is to seal and seal the product. the general process is to heat-press and seal the plastic film with a high-temperature die. there are two-side sealing, three-side sealing, four-side sealing, etc. some of them also require vacuum sealing and sealing. . because the packaging seal works fast and the seal is good, the measurement and control response of the thermostat is required to be fast enough, the temperature control is stable, and the pid control algorithm is accurate to meet the working requirements of the equipment.
penghua machine can process rice, corn, soybeans and wheat in daily life. its main working principle is that the mechanical rotating energy, electric energy is converted into heat energy, and the food generated by the rotation of the machine is used to squeeze the food and puffed the food through high pressure. the role of the temperature control meter is to control the appropriate expansion temperature.
bottled water needs to be sealed after being filled. the temperature control table is used to control the temperature of the hot press mold.
the function of the proximity switch is to sense the position, transmit the position signal to the plc, let the plc program make a logical judgment, and control the corresponding device to work according to the plc programming.
