Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to an automatic feeding mechanism of high-frequency heating equipment. Background Art

[0002] High frequency heating, also known as induction heating, is a method of heating an electrical conductor using electromagnetic induction. It will generate eddy currents in the metal, causing Joule heating of the metal due to resistance. The induction heater consists of an electromagnet through which high frequency alternating current passes. If the object has a large magnetic permeability, it may also generate heat due to losses in the magnetic hysteresis phenomenon.

[0003] When high-frequency heating is performed on the raw materials, the raw materials must first be fed into the high-frequency heating equipment through a feeding mechanism, and the high-frequency heating equipment uses electromagnetic induction to heat the electrical conductor to heat the raw materials. During the transportation of the raw materials, some of the raw materials will have a certain viscosity and will accumulate and stick to the inner wall of the feeding pipe after long-term transportation. At this time, a scraper rod is used to scrape the raw materials on the inner wall. However, after a long period of work, the upper end face of the scraper rod will also be contaminated with more raw materials. These raw materials will accumulate together and stick to the inner wall of the tube body that the scraper rod cannot clean, which can easily cause the tube body to be blocked, slowing down the discharge speed and reducing work efficiency. Therefore, the present application proposes an automatic feeding mechanism for high-frequency heating equipment. Summary of the invention
