Description

Technical Field

[0001] This utility model belongs to the field of weighing and batching, and in particular relates to a pulley weighing and batching machine. Background Technology

[0002] In modern industrial production, especially in industries such as chemicals, building materials, food, pharmaceuticals, and feed, accurate material proportioning and weighing are crucial for ensuring product quality and production efficiency. Traditional batching methods often employ manual weighing or fixed automatic batching systems, which frequently suffer from problems such as low weighing accuracy, low batching efficiency, easy material blockage, severe dust pollution, and inconvenient operation and maintenance.

[0003] Especially in production scenarios requiring the mixing of multiple raw materials in specific proportions, traditional equipment typically uses multiple hoppers fixed in one location, feeding materials sequentially into a fixed weighing container for weighing. This method not only struggles to achieve continuous and efficient batching operations, but also becomes complex and slow-responding when frequent switching or precise control of materials in different hoppers is needed, impacting overall production efficiency. Furthermore, because some materials (such as powders or granules) are prone to bridging, clumping, or adhesion during storage and feeding, uneven feeding or even blockages can occur, further affecting weighing accuracy and production continuity.

[0004] Meanwhile, during the feeding and batching process, especially for powder materials, a large amount of dust is easily generated, which not only affects the working environment but may also endanger the health of operators. If dust enters the equipment, it may also cause mechanical failures or metering errors. Therefore, how to ensure batching accuracy while achieving smooth material feeding, effective dust removal, and stable equipment operation has become a pressing technical problem that batching equipment needs to solve.

The falling material enters the hopper in the corresponding slide weighing assembly below. The hopper monitors the weight of the received material in real time through a weighing sensor, achieving accurate online weighing. After a certain material has been weighed to a quantitative standard, the slide scale assembly moves on the slide rail via a drive motor and a gear and rack transmission mechanism, switches to the bottom of the next hopper, and receives another type of material, thus completing the weighing and batching of multiple materials in sequence; During the material feeding and mixing process, the circulating dust hood and dust suction pipe are connected to the external air source to effectively adsorb the generated dust, prevent dust from overflowing, and ensure a clean and safe working environment.
