Abstract

The invention discloses a switching power supply for a polymer leather spray paint dryer, which is characterized in that it mainly consists of a control chip U, a transformer T, an overvoltage protection circuit, a field effect transistor MOS1, a polarity capacitor C5, a diode D3, a polarity The capacitor C4 is composed of a current adjustment circuit connected with the control chip U, and a photoelectric coupling switch circuit connected with the current adjustment circuit and the secondary inductance coil L3 of the transformer T respectively. The invention can effectively adjust the high-voltage pulse in the voltage and the high-current ripple in the current, so that the dynamics of the voltage and current can be kept stable, thereby ensuring that the invention can output stable voltage and current, and ensure that the polymer leather is sprayed and baked. The stability of the drying temperature of the dryer effectively prevents the deformation or peeling off of the leather surface of the polymer shoe material.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a switching power supply for a polymer leather spray paint dryer. 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] At present, the switching power supply of the polymer leather spray dryer has the problem of unstable output voltage and current, which leads to the extremely unstable drying temperature of the polymer leather spray dryer, resulting in deformation or paint peeling on the surface of the polymer shoe material leather. defect. [0004] Therefore, it is a top priority to provide a switching power supply for a polymer leather...
