Background technique

In recent years, in order to improve the quality of long rod-shaped insulators, the glazing process has gradually abandoned manual operations and replaced it with mechanized glazing, which can steadily improve the appearance and internal quality of products. The purpose of the glazing process is to make the product beautiful and stain-resistant, and to improve the mechanical strength of the product to a certain extent. At present, the most commonly used glaze method for glazing porcelain insulators is the glaze spraying method. During the glaze spraying process, the glaze slurry is diffusely sprinkled on the insulator, and the diameter of the long rod-shaped insulator blank is too thin and the length is too long, resulting in At the same time, the spray glaze method will cause the pollution of the processing and production environment and it is difficult to clean up, so that it will affect the later cleaning of the staff. When using the dip glaze method, it is necessary to put the blank into the glaze liquid bucket and then take it out. Because the blank is too thin or the length is too long, it may cause cracks inside the porcelain insulator and break.
