For hot stamping machine and equipment that heat quickly, the originals are not all manipulated by temperature response, because there is a backwardness from heating to temperature response. Even if the temperature collection is not behind, the temperature is heated to increase the temperature. Transmission takes time. As long as the temperature is slow to modify, it must be stable, and temperature response can be used to manipulate when there is no modification. Otherwise, it is difficult to manipulate as long as the reaction is lagging behind, and the temperature must lag behind from execution to reaction, and the temperature will be more controlled as the speed becomes faster. Therefore, the professional staff of pulse heat press technology does not think that it is only controlled by reaction.
The temperature control of the bronzing machine: the collection rate is generally 200mS, and it can be used for emergence. The rapid temperature increase is mainly the operation of heating output power. The temperature increase cannot rely on PID (the PID when it is stable must be solved by itself) The natural collection rate is immediately advantageous. In addition to the heating output power, the temperature rate is also related to the reaction rate of the sensor. The temperature transmission rate is the main assumption that depends on gas transmission. The size of the sensor is very harmful, even if the gas reaches 300 degrees. The sensor has to lag behind for a period of time to reach 300 degrees, the control measures must be written by itself, and the collection rate need not be too harsh.
Assuming that the temperature rises quickly and the cooling is rapid, PID adjustment is not needed. When the temperature comes, the continuous heating is turned off. The ON/OFF operation of heating again when the temperature is low is not very good. The temperature is simply overshoot. The heating output power should be preset in advance, and the necessary heating power calculation formula should be used to output this output power immediately. If the pulse heat press must be stable enough, a part of it can be used for PID adjustment during stability.
There is also the impact of external temperature, which is related to the working condition of the pulse heat press, but the basic principle of temperature stability is to increase heat generation = heat generation, temperature temperature. The temperature rises when the heating exceeds the heating capacity. If the heating capacity change is not large, you can use the temperature controller PID to adjust, if it is large, you need to assist other skills. Under normal circumstances, the temperature of the pulse hot press can be manipulated according to the above-mentioned method, and the temperature control in an effective range is more conducive to the best working conditions.
