These industries have high requirements for the accuracy of powder weighing. Therefore, using powder weighing equipment can improve production efficiency and product quality. Its function is to achieve accurate measurement of powder.

[0003] Current powder weighing machines typically place the powder to be weighed inside a weighing container and calculate the weight using sensors on the weighing device. However, powder has an absorbent nature, so the weighing container still needs to be manually cleaned after use to ensure measurement accuracy, which is time-consuming, labor-intensive, and reduces work efficiency. Summary of the Invention

[0004] This invention provides a weighing machine suitable for powder materials, which can clean the powder material adhering to the inside of the placing cup by driving the cleaning mechanism through the pressure cylinder, thereby saving time and effort and improving work efficiency.

[0005] To achieve the above objectives, a weighing machine suitable for powders is provided, comprising a connecting plate, a connecting plate fixedly connected to the upper surface of the connecting plate, a pressure cylinder fixedly mounted on the upper bottom surface of the connecting plate, a fixing ring disposed above the connecting plate, a support leg fixedly connected to the bottom surface of the fixing ring, the bottom end of the support leg fixedly connected to the upper surface of the connecting plate, a placement cup fixedly connected inside the fixing ring, a cleaning mechanism disposed inside the placement cup, a middle part of the telescopic end of the pressure cylinder fixedly connected to the cleaning mechanism, the bottom of the telescopic end of the pressure cylinder passing through the cleaning mechanism, a base fixedly connected to the bottom of the telescopic end of the pressure cylinder, and a weighing sensor fixedly connected below the connecting plate, with a mounting base fixedly mounted on the bottom surface of the weighing sensor. By placing the powder to be weighed inside the placement cup, after placement, the weighing sensor weighs the placed powder. After weighing, the pressure cylinder drives the cleaning mechanism and the base to move downwards. During the movement, the base releases the weighed powder, and the cleaning mechanism cleans the powder adhering to the inner wall of the placement cup during release.

[0006] According to the aforementioned weighing machine suitable for powder materials, the cleaning mechanism includes a scraper, a sliding rod, a spring, a sliding groove, a sliding block, a scraper block, and a driving block, wherein the driving block is disposed at the center of the inner cavity of the placing cup. The positional relationship between the driving block and the placing cup ensures more uniform contact between the scraper and the inner wall of the placing cup.

[0007] According to the aforementioned weighing machine suitable for powders, the drive block has holes on the side near the inner wall of the placement cup, and there are several holes. The sliding rod is slidably connected to the inner side of the holes. By configuring the sliding rod to cooperate with the holes, the sliding rod can extend and retract when subjected to force.

[0008] According to the aforementioned weighing machine suitable for powder materials, the scraper is fixedly connected to the side of the sliding rod near the inner wall of the placement cup, and the scraper is in contact with the inner wall of the placement cup. By setting the scraper to contact the inner wall of the placement cup, the scraper can scrape off the powder adhering to the inside of the placement cup when it moves.

[0009] According to the aforementioned weighing machine suitable for powder materials, the spring is sleeved on the outside of the sliding rod, and the two ends of the spring are respectively fixedly connected to the scraper and the drive block on their respective sides. The spring ensures that the sliding rod constantly pushes the scraper to scrape.

[0010] According to the aforementioned weighing machine suitable for powder materials, the sliding groove is formed on the upper surface of the scraper. Two sliding grooves are provided and symmetrically arranged. The number of sliding blocks corresponds to the number of scrapers. The two ends of each sliding block are slidably connected to the two sliding grooves on adjacent sides. By setting the sliding blocks, the scrapers can be connected, making the synchronous movement of the scrapers more stable.

[0011] According to the aforementioned weighing machine suitable for powder, the scraper is fixedly connected to the upper surface of the sliding block, and the scraper contacts the inner wall of the placement cup. The lower end of the placement cup is inclined. By setting the lower end of the placement cup to be inclined, the powder is concentrated towards the inclined area, reducing the problem of powder dispersion and difficulty in collection.

[0012] According to the aforementioned weighing machine suitable for powder materials, a reinforcing column is fixedly connected to the upper end of the drive block, and the upper end of the reinforcing column passes through the upper surface of the connecting plate and extends upwards. By setting the reinforcing column and the drive block to cooperate with each other, the drive block is further limited, making the movement of the drive block more stable.

[0013] The beneficial effects of this utility model are as follows: by setting up a cup placement mechanism, a cleaning mechanism and a base, the pressure cylinder pushes the cleaning mechanism and the base to move downward. When the base moves, it releases the powder weighed by the weighing sensor. When it is released, the cleaning mechanism cleans the powder adhering to the inner wall of the cup, thus eliminating the need for manual cleaning, saving time and effort, and improving work efficiency.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
