A heating device for piezoceramic dispensing valves

Abstract

This utility model discloses a heating device for a piezoelectric ceramic dispensing valve, relating to the technical field of dispensing valve heating equipment. A motor shaft is located at the bottom of the motor, extending through the top of the inner cavity of the heating device body. A horizontal bar is located at the bottom of the motor shaft, with vertical bars on both the left and right sides of the bottom of the horizontal bar. Scrapers are located on opposite sides of the vertical bars, with the ends of the scrapers furthest from the vertical bars connected to the inner wall of the heating device body. When heating the adhesive, the motor drives the horizontal bar via the motor shaft to rotate at the top of the inner cavity of the heating device body. This rotation drives the scrapers via the vertical bars, allowing the scrapers to scrape off the adhesive from the inner wall of the heating device body. This not only prevents the adhesive from hardening due to adsorption but also achieves a stirring effect, resulting in more uniform heating of the adhesive.
