Automatic polymer leather paint spraying system based on variable low-pass filter circuit

Abstract

The invention discloses an automatic polymer leather paint spraying system based on a variable low-pass filter circuit. The automatic polymer leather paint spraying system based on the variable low-pass filter circuit is mainly composed of a central processing unit, a displayer, a power source, a pre-storage module, a color mark sensor, an inversion sensor, a rotation sensor, a displacement sensor, an electromagnetic valve, a motor driver, a charging tray reversing motor, a spray head rotating motor and a spray head displacement motor, wherein the displayer, the power source, the pre-storage module, the color mark sensor, the inversion sensor, the rotation sensor, the displacement sensor, the electromagnetic valve and the motor driver are all connected with the central processing unit, and the charging tray reversing motor, the spray head rotating motor and the spray head displacement motor are all connected with the motor driver. The automatic polymer leather paint spraying system based on the variable low-pass filter circuit is characterized in that the low-pass filter circuit is further connected between the color mark sensor and the central processing unit in series, and a thyristor coupling type trigger switch circuit is further connected between the central processing unit and the electromagnetic valve in series. By the adoption of the automatic polymer leather paint spraying system, the paint spraying efficiency and the paint spraying sensitivity can be effectively improved, the paint spraying range can be effectively widened, and the paint spraying stability and paint spraying accuracy of a polymer leather paint spraying machine can be effectively guaranteed; in addition, the consistency of the chromophore numerical values and the glossiness of the paint-spayed surface of polymer leather is guaranteed, the working time is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an automatic paint spraying system for polymer leather based on a variable low-pass filter 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 process of spraying paint on polymer leather. At present, traditional polymer leather spraying machines are generally controlled in a semi-automatic or manual manner. Due to the poor stability and accuracy of the spraying of the leather spraying machines controlled by these two methods, the polymer leather is prone to uneven spraying. Make the glossiness of the paint surface of the polymer leather inconsistent. Contents of the invent...
