When the train is running and braking, the brake shoe rubs against the wheel to stop the train, which belongs to the braking device. The brake shoe includes various materials selected according to the friction characteristics and the wear life of the wheel contact surface. Many brake shoes are composites of multiple materials with different characteristics. The brake shoe is formed by pouring in a production line after mixing and blending various raw materials. The ratio and dosage of the raw materials directly affect the forming quality of the brake shoe. In particular, the weight of the raw materials after mixing directly affects the forming weight of the brake shoe. Non-uniformity will affect its shock absorption and noise reduction effects. For the forming consistency and uniformity of the brake shoe, the mixed raw materials need to be weighed before entering the pouring process. When the powdery materials for mixing and batching fall from the batching equipment to the weighing equipment, their impact force and concentrated accumulation will affect the use accuracy and service life of the weighing equipment.
