[0002] The star feeder is a common quantitative conveying device for powdery materials. However, in actual use, powdery granules are often affected by physical factors such as the granule structure, pressure, and moisture, which can cause agglomeration and adhesion of the powder in the silo inside the star feeder. When the feeder is operating normally, the star wheel rotates to drive the powder to fall to the discharge port; when the powder agglomerates and sticks in the internal silo of the feeder, it is easy to cause agglomeration and adhesion of the powder in the feeder, making it impossible for the feeder to carry out normal quantitative material delivery.

[0003] In order to solve the defects and shortcomings of the star-shaped feeder mentioned above during use and prevent agglomeration and adhesion in the internal bin of the feeder, a self-cleaning star-shaped feeder is provided. Summary of the invention

[0023] The present invention provides a self-cleaning star feeder, comprising: a feed port 1, a star wheel rotor 2, a rotating shaft 3, a discharge port 4, a metal scraper 5, an annular guide shaft 6, a scraper plate 7, a guide shaft 8, a scraper plate guide rail hole 9, a metal serrated scraper 10, a metal scraper guide rail hole 11, a shell 12, and a first rotating page 13-1 to a sixth rotating page 13-6.

[0024] like Figure 1 As shown, a self-cleaning star feeder includes a shell 12, one end of the shell 12 is provided with a feed port 1, and the other end is provided with a discharge port 4. The powder enters the feeder from the feed port 1, and the powder is transported out from the discharge port 4. A star rotor 2 is provided inside the shell 12, and the star rotor 2 is provided with a rotating shaft 3 and a plurality of rotating leaves 13. The powder enters the star rotor 2 in the feeder from the feed port 1, and when the rotating shaft 3 drives the star rotor 2 to rotate, the powder in the silo is transported to the discharge port 4. The rotating shaft 3 is connected to an external motor, and the rotating shaft 3 is rotated by operating the external motor, so that the rotating shaft 3 drives the star rotor 2 to rotate. The star rotor 2 is provided with an annular guide rail, and the annular guide rail is covered with a scraper 5. The scraper 5 slides on the annular guide rail between adjacent rotating leaves 13 to loosen the powder.

[0025] like Figure 1-3 As shown, the annular guide rail is an annular guide shaft 6 arranged in the planetary rotor 2. The annular guide shaft 6 is perpendicular to the rotating page 13. The annular guide shaft 6 is concentrically arranged with the rotating shaft 3, and is fixed on the rotating page 13 and rotates with the rotating page 13.

[0026] The scraper is a metal scraper 5, and the metal scraper 5 is also sleeved on the annular guide shaft 6. The metal scraper 5 is on the annular guide rail between adjacent rotary pages 13. The rotating shaft 3 drives the rotary pages 13 to realize rotational operation. When the rotation angle of the rotary pages 13 changes, each metal scraper 5 can slide back and forth between adjacent rotary pages 13. The metal scraper 5 is composed of a plurality of transverse metal sawtooth scrapers 10 and two vertical metal rods with guide rail holes 11. The metal sawtooth scraper 10 is sawtooth-shaped, wherein the vertical metal rod is provided with a guide rail hole 11, the sawtooth gap of the metal scraper 5 is dislocated, and the annular guide shaft 6 passes through the guide rail hole 11 in the metal scraper 5. The metal scraper 5 can slide back and forth on the annular guide shaft 6.

[0027] Taking the first rotary page 13-1, the second rotary page 13-2 and the metal scraper 5 in between as an example, when the star-shaped feeder 2 starts to rotate clockwise from the feed port 1, driven by the rotating shaft 3, assuming that the star wheel rotor rotates clockwise, when the star wheel rotor 2 rotates to the right and downward, the metal scraper 5 slides downward in an arc along the annular guide shaft 6 under the action of gravity, away from the first rotary page 13-1 and gradually approaches the second rotary page 13-2. In this process, the metal scraper 5 loosens the powder. When the metal scraper 5 slides to the second rotary page 13-2 under the action of gravity, it can also have the effect of knocking and vibrating the second rotary page 13-2, further loosening the powder and facilitating the powder to fall off and slide out; after the star wheel rotor 2 discharges the powder at the discharge port 4, it continues to rotate clockwise toward the feed port 1. During the rotation of the star wheel rotor 2, the metal scraper 5 slides to the side of the first rotary page 13-1 along the annular guide shaft 6 under the action of gravity.

[0028] A guide shaft 8 is provided between adjacent hinges 13, and a scraper plate 7 is sleeved on each guide shaft 8. A scraper plate guide hole 9 is provided on the scraper plate 7. The diameter of the scraper plate guide hole 9 is slightly larger than the outer diameter of the guide shaft, so as to ensure that the scraper plate 7 can slide along the axial direction of the guide shaft 8. The guide shaft 8 is arranged along the radial direction of the rotating shaft 3 and perpendicular to the rotating shaft 3. One end of the guide shaft 8 is fixed on the rotating shaft 3, and the other end passes through the scraper plate guide hole 9 and is connected to the scraper plate 7. A stop end is provided at one end of the guide shaft 8 away from the rotating shaft 3 to prevent the scraper plate 7 from sliding down along the guide shaft 8. The scraper plate 7 can be a straight plate or an arc plate. During operation, when the planetary rotor 2 rotates to the position of the feed port 1, the powder is transported to the silo composed of the rotating shaft 3 and the rotating blade 13 of the planetary rotor 2. Due to the effect of gravity, the scraper plate 7 located near the feed port 1 moves away from the limit end and closer to the rotating shaft 3; when the planetary rotor 2 rotates to the discharge port 4, the scraper plate 7 located near the discharge port 4 also moves away from the rotating shaft 3 near the limit end due to the effect of gravity. In this way, during the rotation of the planetary rotor 2, multiple scraper plates 7 slide back and forth on the guide shaft 8, thereby pushing the powder stored in the silo between the rotating shaft 3 and the rotating blade 13 to be transported to the discharge port 4, playing the role of scraping.

[0029] The specific working process of the present invention, taking the first rotary page 13-1, the second rotary page 13-2 and the metal scraper 5 therebetween as an example, is as follows: the relevant staff starts the external motor, and the external motor drives the rotating shaft 3 to rotate, thereby driving the planetary rotor 2 to rotate through the rotating shaft 3. When the planetary rotor 2 rotates to the top position of the feed port 1, the relevant staff delivers the powder to be transported to the feed port 1 of the planetary rotor 2, and then the powder enters the material bin of the planetary rotor 2, and the scraper plate 7 slides and falls to the bottom of the guide shaft 8 (close to the rotating shaft 3). Then the planetary rotor 2 continues to rotate, and when the planetary rotor 2 rotates to the side of the shell 12, the metal scraper 5 uses the gravity of the metal scraper 5 to slide in an arc along the annular guide shaft 6, and the structure of the loose powder is loosened during the sliding process. Then the star rotor 2 continues to rotate. When the star rotor 2 rotates to the discharge port 4 at the bottom of the housing 12, the metal scraper 5 uses the gravity of the metal scraper 5 to slide from the first rotary page 13-1 to the second rotary page 13-2 along the annular guide shaft 6. When the metal scraper 5 contacts the second rotary page 13-2, the metal scraper 5 knocks and vibrates the second rotary page 13-2, knocking the powder attached to the second rotary page 13-2 off, further loosening the powder, and facilitating the powder to fall off and slide out. And when the star rotor 2 rotates to the discharge port 4 at the bottom of the housing 12, the scraper plate 7 moves downward along the guide shaft 8 under the action of the scraper plate 7's own gravity, pushing the powder between the rotating shaft 3 and the first rotary page 13-1 and the second 13-2 to be transported to the discharge port 4.

[0030] After the star rotor 2 discharges the powder at the discharge port 4, it continues to rotate toward the feed port 1. During the rotation of the star rotor 2, the metal scraper 5 slides to the first rotary leaf 13-1 side along the annular guide shaft 6 under the action of gravity and stays there. When the scraper plate 7 turns to the feed port 1 after the star rotor 2 turns, it falls back along the guide shaft 8 to the bottom of the guide shaft 8 (close to the rotating shaft 3) under the action of its own gravity.

[0031] In the prior art, during actual use, powdered granular materials are often affected by physical factors such as the granular structure, pressure, and moisture, which may cause agglomeration and adhesion of the powder in the silo inside the star feeder over time. When the feeder operates normally, the star-shaped wheel rotates to drive the powder to fall to the discharge port; when the powder agglomerates and adheres in the internal silo of the feeder, it is easy to cause agglomeration and adhesion of the powder in the feeder, making it impossible for the feeder to carry out normal quantitative material transportation. The device of the present invention provides a self-cleaning star feeder with a stable structure and automatic cleaning, which can ensure quantitative and stable transportation of powder. It can effectively avoid the agglomeration and blockage of the powder in the feeder caused by the agglomeration and adhesion of the powder, and ensure that the feeder can carry out normal quantitative material transportation with stable gears.

[0032] The above description of the present invention is only a preferred implementation mode of the present invention application in combination with the accompanying drawings, but is not intended to limit the scope of protection of the present invention application. It should be pointed out that for technical personnel in the relevant field, without departing from the overall concept of the present invention, any modifications, equivalent substitutions, improvements, etc. made by technical personnel in this field without creative labor should be included in the scope of protection of the present invention application.
