Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts production, specifically is a raw material mixing device for automobile brake pad production. BACKGROUND

[0002] In the production process of automobile brake pads, uniform mixing of raw materials is crucial. Brake pads need to have stable and reliable friction performance. If the raw materials are not mixed evenly, there will be differences in their internal structure, which will cause severe local wear and unstable braking force in use, seriously affecting driving safety.

[0003] In the production of existing automobile brake pads, workers often directly pour various different raw materials into a fixed mixing container, then start the mixing equipment and perform single-direction mixing. Because the mixing method is too simple and mechanical, raw materials of different densities and textures are difficult to fully blend. For example, heavy metal powder is easy to sink to the bottom of the container, while light fiber materials are gathered at the top, making it difficult to achieve uniform distribution in single-direction mixing. This insufficient mixing causes serious unevenness in the internal structure of the brake pad. In actual use, the brake pad may experience severe local wear, resulting in a significant reduction in its service life. At the same time, due to uneven distribution of friction materials, the braking force produced during braking is unstable, seriously affecting the braking effect and thus posing a great risk to driving safety, which cannot meet the demand for high-performance brake pads for modern automobiles.
