Description

Technical Field

[0001] The utility model relates to the technical field of material production batching lines, in particular to an automatic batching weighing device for brake shoes. Background Art

[0002] Composite brake shoes are one of the special accessories for railway vehicles. When the train is running and braking, the friction between the brake shoes and the wheels stops the train from running. They belong to the braking device. Brake shoes include various materials selected according to the friction characteristics and the impact on the wear life of the wheel contact surface. Many brake shoes are composites of multiple materials with different characteristics. Before the production process of brake shoes, the raw materials need to be weighed and batched, and then the batched materials are transferred to the next station (temporary storage or mixed processing). In the existing process, the operator usually moves the container to the bottom of the material conveying pipe of one material for filling and weighing. After the filling is completed, the container is moved to the bottom of the material conveying pipe of the next material for filling and weighing. This is repeated until all materials are filled and weighed, and then the container is moved to the next station. The handling process is cumbersome and time-consuming, and the filling and weighing operations consume a lot of labor for personnel. Therefore, an automatic batching weigher for brake shoes is proposed to realize the automated flow operation of weighing, filling and transportation, and improve the batching efficiency.
