Description

Technical Field

[0002] Weighing: measuring data related to quality, usually weight. When used as a noun, it means the process of measuring quality.

[0003] Most of the existing raw material weighing devices install weighing sensors on the surface of the raw material placing plate. Most of the raw material placing plates are arranged in an inclined shape. The raw materials on the surface of the raw material placing plate are poured into a discharge pipe through the inclined surface, and the raw materials are discharged through the discharge pipe. However, the raw materials on the surface of the raw material placing plate are poured into the discharge pipe by gravity, and a small amount of raw materials will remain on the surface of the raw material placing plate, which is inconvenient for weighing and discharging other raw materials later. In addition, the raw materials are easily moldy and rotten when they are piled up inside the weighing device for a long time, which affects the normal use environment of the weighing device. Therefore, a precise raw material weighing device is needed. Utility Model Content

[0025] The raw material box 19 is arranged inside the distribution box 3, and a movable moving block 13 is arranged on the side wall of the distribution box 3 above the raw material box 19, and at the same time, the side wall of the moving block 13 at one end away from the raw material box 19 is slidably connected to the inner side wall of the discharge pipe 9, and the moving block 13 is driven to move by the driving assembly, so that the moving block 13 drives the scraper 14 fixedly installed below to scrape the raw materials on the surface of the placement plate 17 inside the raw material box 19, thereby ensuring the weighing environment of the surface of the placement plate 17.

[0026] The driving assembly includes a rotating motor 10 and a rotating rod 11. The rotating motor 10 is fixedly installed on the side wall of the material distribution box 3. One end of the rotating rod 11 passes through the side wall of the material distribution box 3 and is keyed to the output shaft of the rotating motor 10.

[0028] The length of the thread groove 12 is the same as the inner diameter of the raw material box 19. By setting the length of the thread groove 12 to be the same as the inner diameter of the raw material box 19, it is ensured that the moving block 13 can reciprocate on the side wall of the thread groove 12 to fully scrape the raw materials on the surface of the placement plate 17.
