Explosion-proof heating glass cup body manufacturing method

Abstract

The manufacturing method of the explosion-proof heated glass cup body is characterized in that it includes the following steps: the glass cup body adopts a blowing process, the outside of the glass cup body is covered with a protective film, the protective film is as close as possible to the outer wall of the cup body, and the glass cup The outside of the main body is completely wrapped; heat the glass body and the protective film together, and the protective film shrinks and fits the outer wall of the glass cup; place the heated protective film glass body on the table, rotate it and use a knife to cut the glass Cut off the protective film on the upper and lower steps of the cup body; inject glue into the upward annular opening on the periphery of the heating plate, and then insert the lower opening of the explosion-proof glass cup into the glue on the upward annular opening on the periphery of the heating plate, so that the cup The inner wall and outer wall of the opening under the body are bonded and sealed with the glue of the upward annular opening on the periphery of the heating plate; the invention has the advantages of simple and reasonable structure, less processing and manufacturing procedures, high production efficiency, good explosion-proof, prolonged service life, safety and reliability, and beautiful appearance Elegant features.

Description

technical field [0001] The invention relates to a method for manufacturing an explosion-proof heated glass body. Background technique [0002] The electric kettle is one of the commonly used small household appliances, which is used to heat water, and can be used as a container for water at the same time, and has the characteristics of being easy to use. Most of the existing technologies use glue to connect and seal between the glass body and the heating plate, or silica gel to connect and seal, such as: the invention of Chinese Patent No. ZL200720171554. The open kettle body and the heating disc connected to the lower opening of the kettle body, the electric connector which can be rotated arbitrarily and the electric heating connection base of the kettle, the kettle body is connected to the heating disc by high temperature resistant non-toxic adhesive, the The heating plate is provided with a temperature detection and control adjustment device and a water level detection d...

AI Technical Summary

Problems solved by technology

Since there are no anti-collision measures on the outside of the glass body, the glass body is easy to hit and burst and hurt people when it is not used normally, and there are potential safety hazards.
