[0002] With the development of modern industrial technology, the demand for high-precision cutting tools is increasing. Under this background, diamond wire emerges as the times require as a kind of efficient and precise cutting material. Diamond wire is mainly applied to the cutting process of hard and brittle materials such as crystalline silicon and sapphire, and is known for its excellent hardness and wear resistance. It not only improves the efficiency of material cutting, but also greatly reduces the material loss in the cutting process, so it has been widely used in the fields of solar photovoltaic industry, semiconductor manufacturing and jewelry processing.

[0003] The production process of diamond wire mainly includes the selection and processing of metal bus, the attachment of diamond powder (sand coating process) and other steps. Among them, uniformly attaching fine diamond powder to the metal bus is the key link of the whole production process. In this process, the diamond powder needs to be accurately and uniformly delivered to the designated position for subsequent sand coating operation through a feeding groove.

[0004] However, in actual production equipment, fine powder materials such as diamond powder are difficult to be quantitatively delivered due to their poor flowability and easy adhesion in the process of micro-uniform delivery. Especially in the case of micro-uniform addition, it is difficult to achieve precise control like liquid. Secondly, due to the easy adhesion of the powder material itself, it is not easy to separate uniformly during delivery, which further affects the uniformity of material flow. These problems eventually lead to poor performance in continuous delivery, which cannot guarantee the continuity and stability of production. UTILITY MODEL CONTENTS
