Enameled wire baking dynamic temperature control device and working method thereof

Abstract

The invention discloses a dynamic temperature control device for enameled wire baking includes a baking chamber, a cooling assembly disposed at an outlet of the baking chamber and a temperature control assembly disposed downstream of the cooling assembly, wherein the cooling assembly includes a variable frequency blower, wherein an air outlet of the variable frequency blower is aligned with an enameled wire sent out from the outlet of the baking chamber for air cooling treatment of the enameled wire; The temperature control assembly includes an integrated auxiliary heating unit and a temperature detection unit, wherein, the auxiliary heating unit and the enameled wire fed into the temperature control assembly are heat exchanged so that the enameled wire temperature sent out by the temperature control assembly reaches a predetermined finished product temperature value; The temperature detection unit is used for real-time monitoring and collecting the enameled wire temperature at the temperature control component, wherein, based on the temperature difference between the real-time line temperature value monitored by the temperature detection unit and the temperature value of the auxiliary heating unit, the air outlet quantity of the variable frequency fan is dynamically adjusted until the auxiliary heating unit and the enameled wire temperature are equal.

Description

technical field [0001] The invention relates to the technical field of enameled wire production and processing, in particular to an enameled wire baking dynamic temperature control device and a working method thereof. Background technique [0002] The production process of enameled wire is generally drawing, annealing, painting, baking, cooling and winding. Among them, the painting, baking and cooling processes need to go through 10 to 14 reciprocating cycles continuously, and the temperature stability of the wire temperature after cooling is directly It affects the painting and baking effect of the next cycle, thus affecting the quality and performance of the product. Since in the actual production process, the running speed of the enameled wire and the temperature of the baking furnace are fixed, among them, if the temperature of the enameled wire after cooling is low, it will lead to incomplete baking of the paint film after painting; If the wire temperature of the ename...

AI Technical Summary

Problems solved by technology

Since in the actual production process, the running speed of the enameled wire and the furnace temperature of the baking furnace are fixed, among them, if the temperature of the enameled wire after cooling is low, it will lead to incomplete baking of the paint film after painting; If the temperature of the enameled wire is high, it will lead to excessive baking of the paint film after painting. These problems are not good for the production of enameled wire.

However, the cooling of the wire in the circuit of the traditional enamelled machine is directly supplied by the fan, and the air volume is not controlled. Moreover, due to the difference in ambient temperature and season, the fluctuation of the wire temperature after cooling is also different, which is not conducive to the control of the performance of the enameled wire. , so solving the dynamic control of enameled wire temperature is of vital significance for product quality performance
