[0017] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Example

[0018] like Figs. 1-3As shown, this embodiment is a quantitative distribution wheel, including a distributing cylinder 1. A rotating central shaft 3 is disposed within the inner cavity of the distributing cylinder 1, and a distributing partition 2 is disposed on the rotating central shaft 3. A feed inlet is disposed on the side wall of the distributing cylinder 1, and a powder inlet pipe is connected to the outside of the feed inlet for feeding powder into the distributing cylinder 1. A baffle plate 7 is also disposed inside the distributing cylinder 1, located above the distributing partition 2 and below the feed inlet. A discharge port is disposed at the bottom of the distributing cylinder 1, and the discharge port is connected to a powder outlet pipe 5. The lower end of the rotating central shaft 3 passes through the bottom of the distributing cylinder 1 and is connected to a motor 9. The bottom of the distributing cylinder 1 can be a flange.

[0019] In this embodiment, there are multiple material distribution partitions 2, which are evenly arranged around the rotation center axis 3, so that adjacent material distribution partitions 2 form material distribution chambers of the same volume. All material distribution partitions 2 are vertical and extend radially along the material distribution cylinder 1. The size of the discharge port is adapted to the material distribution chamber. The discharge port is located directly below the baffle plate 7.

[0020] In this embodiment, the baffle plate 7 is horizontally arranged, and its lower surface is flush with the top of the distribution partition plate 2. The area of ​​the baffle plate 7 covers one-third of the distribution cavities. When the distribution partition plate 2 rotates, only the powder inside the distribution cavity can be pushed below the baffle plate 7 and discharged from the outlet below the baffle plate 7.

[0021] In this embodiment, a fixed sleeve 6 is provided outside the rotating central shaft 3, and a scraper 61 is provided on the fixed sleeve 6. When the fixed sleeve rotates with the rotating central shaft 3, the scraper 61 can stir and disperse the powder in the distributing cylinder 1, so that the powder falls more smoothly into the distributing cavity formed by the distributing partition 2.

[0022] In this embodiment, a pneumatic thin ball valve 41 is provided on the powder inlet pipe, which is used to control the opening and closing of the powder inlet pipe.

[0023] In this embodiment, the rotating central shaft 3 is fixed to the bottom plate of the distributing cylinder 1 by a bearing structure. The bearing structure may include deep groove ball bearings, thrust ball bearings, and corresponding sealing rings. The lower end of the rotating central shaft 3 is connected to the motor 9 via a coupling 8. The bottom of the distributing cylinder 1 may be a flange, which is fixedly connected to the motor 9 as a whole by a flange structure.

[0024] The working process of the quantitative distribution wheel in this embodiment is as follows: First, the pneumatic thin ball valve 41 is opened, allowing the powder to enter the distribution cylinder 1 from the powder feeding pipe 4. Under the action of the baffle plate 7, the powder cannot be directly discharged from the powder outlet pipe 5, but will first fall into the distribution chamber formed by the distribution partition plate 2. When the powder in the distribution cylinder 1 reaches a certain amount, the distribution chamber not covered by the baffle plate 7 will be filled with powder. At this time, the motor 9 can be started, causing the motor 9 to drive the rotating central shaft 3 to rotate at a certain angle. At this time, the distribution partition plate 2 will also rotate synchronously at the corresponding angle, thereby distributing the powder. The powder in the chamber also moves sequentially to the corresponding angular position. Since the lower surface of the baffle plate 7 is flush with the upper end of the distribution partition plate 2, when the distribution chamber is rotated below the baffle plate 7, only the material inside the distribution chamber can enter below the baffle plate 7, thus ensuring that the volume of material in each distribution chamber is the same (i.e., achieving quantitative function). When the distribution chamber is opposite to the discharge port below the baffle plate 7, a specific amount of powder in the distribution chamber can flow out from the powder discharge pipe 5; when the empty distribution chamber rotates out from below the baffle plate 7, it can be refilled with powder; and so on. By controlling the rotation parameters of the motor 9, quantitative distribution (feeding) can be achieved.

[0025] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
