Description

TECHNICAL FIELD

[0001] The utility model relates to foundry technology field, concretely is a raw material quantitative feeding device based on foundry processing. BACKGROUND

[0002] In the field of foundry processing, the quantitative feeding of raw materials is a crucial link. Traditional feeding methods often rely on manual operation, which has many shortcomings. First, manual operation cannot guarantee the accuracy and stability of raw material addition, which can easily lead to excessive or insufficient addition of raw materials, affecting the quality and production efficiency of castings. Second, manual operation has a high safety risk, and operators may be at risk of burns or poisoning when handling high-temperature molten materials or harmful substances.

[0003] Referring to the patent entitled "Water glass casting raw material melting device" (publication number CN220759194U, publication date April 12, 2024), by setting an arc-shaped filter plate, a rotating block, and a drive motor, a large amount of heat is generated by starting the heating chamber. The fan transfers the heat to the gas booster, which compresses and pressurizes the hot air to the melting chamber to increase the temperature and melt the water glass casting raw material on the arc-shaped filter plate. At the same time, due to the operation of the drive motor, the rotating rod drives the rotating block to rotate, which in turn causes the rotating block to rotate and scrape the water glass casting raw material on the arc-shaped filter plate, preventing the water glass casting raw material from accumulating and melting.

[0004] The above patent specifically uses a manual addition method for feeding. However, with the continuous development of industrial automation, manual operation cannot meet the high requirements of modern foundry processing for production efficiency and product quality. Most existing quantitative feeding devices use simple mechanical structures such as handheld storage bins and handheld baffles, and the addition of raw materials is achieved by manually controlling the opening and closing of the storage bin discharge port. This method is not only cumbersome to operate, but also has poor synchronization and safety. The addition of raw materials is very unstable due to operational errors, often leading to an increase in the scrap rate of castings. Therefore, the utility model provides a raw material quantitative feeding device based on foundry processing. UTILITY MODEL CONTENTS
