Tire extruder temperature control device and control method thereof

Abstract

The invention discloses a tire extruder temperature control device which comprises a cooling device, a heating device and a temperature control device, wherein the temperature control device comprises a proportion integration differentiation (PID) controller and a temperature lower limit alarming terminal, the heating device is connected with the temperature lower limit alarming terminal, and the cooling device is connected with the PID controller. The tire extruder temperature control device is characterized in that a temperature value set by the existing unique PID controller is changed to be a range value by aid of the temperature lower limit alarming terminal. The temperature lower limit alarming terminal in the temperature control device is actually the temperature lower limit alarming terminal which is arranged in an alarming device of the existing tire extruder device, and the heating device is merely needed to be connected with the temperature lower limit alarming terminal in the alarming device.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a tire extruder temperature control device and a control method thereof. Background technique [0002] The temperature control of the tire extruder equipment is very important, and it has a great impact on the quality of the rubber compound it extrudes. At present, intelligent instrument control is mostly used. In actual production, no matter which season the tire extruder is in production, it will By setting the first temperature value, the operation adjustment of the automatic PID controller in the instrument is carried out, and the switching control of heating and cooling is controlled to ensure that the temperature of the equipment is controlled at the first set temperature value. During the production and extrusion process of the rubber material, due to the friction between the rubber material and the pins and barrels, the temperature of the equipment itself will...

AI Technical Summary

Problems solved by technology

During the production and extrusion process of the rubber material, due to the friction between the rubber material and the pins and barrels, the temperature of the equipment itself will increase. Once the temperature increases, the PID controller will start cooling, and in different seasons, the temperature of the cold water Inconsistency, it is easy to cause excessive cooling inertia during cooling, resulting in low temperature, then the PID controller will start heating again, which will cause frequent starting of the heating device and cooling device, wasting electric energy
