Intelligent paint dryer temperature-control system based on A/D converting circuit

Abstract

The invention discloses an intelligent paint dryer temperature-control system based on an A / D converting circuit, and the system mainly comprises a central processor, and a display, a power supply, a temperature sensor, a temperature controller and a data memory that are all connected with the central processor, and a heater connected with the temperature controller. The system is characterized in that an A / D converting circuit is in series connection between the temperature sensor and the central processor; a rectification filtering voltage stabilizing circuit is in series connection between the power supply and the central processor; a current driving circuit is in series connection between the temperature controller and the heater; and the A / D converting circuit comprises an amplification contrast circuit and an integration operation circuit. The temperature intelligent control system has the advantages of raising the temperature-sensitive accuracy and temperature stability of a high-molecular leather paint dryer; preventing high-molecular footwear leather surfaces from deformation and preventing the paint of the footwear leather surfaces from falling off; saving workmanship time greatly; and reducing cost.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an intelligent temperature control system for an intelligent spray paint dryer based on an A / D conversion circuit. Background technique [0002] As polymer leather is widely used in the leather products industry, while people have higher and higher requirements for the quality of leather products, they also put forward higher requirements for the quality of polymer leather. However, to produce high-quality polymer leather, the key lies in the step of drying the polymer shoe material leather after painting. [0003] However, the temperature control system of the traditional polymer leather spray paint dryer is relatively simple, and a power-off thermostat with a bimetal shrapnel structure is often used as the temperature control system on the heater. The bimetal shrapnel of this kind of power-off thermostat is easy to deform due to long-term high temperature, ...
