[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6This embodiment provides a technical solution: a powder material conveying mechanism, which includes a housing 1, with uniformly distributed hoppers 3 inside the housing 1, a conveying mechanism 2, and a controller 11 outside the powder material conveying mechanism. The input end of the controller 11 is electrically connected to an external power source. A feed hopper 5 is provided on the upper right side of the housing 1, and a discharge hopper 7 is provided on the lower left side of the housing 1. A lever 6 is rotatably connected between the left and right inner walls of the feed hopper 5. A lever motor is provided on the right side of the feed hopper 5, and the output shaft of the lever motor is fixedly connected to the right side of the lever 6. The input end of the lever motor is electrically connected to the output end of the controller 11. A bracket 9 is provided on the lower side of the housing 1. The bracket 9 can be added by the user according to the redo process. It can be installed by hoisting or vertical mounting. When the conveying mechanism is needed, the external powder material can be fed into the interior of the housing 1 through the feed hopper 5.

[0026] Conveying mechanism 2: It includes a first rotating shaft 21, a transmission wheel 22, a conveyor belt 24, a fixed block 25, a second rotating shaft 26, a connecting rod 27, a third rotating shaft 28, and a fixed seat 29. The first rotating shaft 21 is symmetrically rotatably connected between the front and rear inner walls of the housing 1. The outer arc surfaces of the two first rotating shafts 21 are respectively fixedly fitted with transmission wheels 22. The two transmission wheels 22 are connected by a conveyor belt 24. The outer surface of the conveyor belt 24 is fixedly connected with evenly distributed fixed blocks 25. The middle part of the fixed blocks 25 is rotatably connected to the second rotating shaft 26. The outer arc surfaces of the second rotating shaft 26 are symmetrically fixedly connected with connecting rods 27. The third rotating shaft 28 is fixedly connected between every two longitudinally adjacent connecting rods 27. The middle part of the outer arc surface of the third rotating shaft 28 is respectively fixedly connected to the connecting rods 27. A fixed base 29 is rotatably connected to the outer surface of each pair of fixed bases 29, and a hopper 3 is fixedly connected to each pair of fixed bases 29. The diameter of the left drive wheel 22 is different from that of the right drive wheel 22, with the left drive wheel 22 having a larger diameter than the right drive wheel 22. The conveying mechanism 2 also includes support rollers 23, which are uniformly rotatably connected between the front and rear interiors of the housing 1. The outer arc surfaces of the eighteen support rollers 23 are all rotatably connected to the inner side of a conveyor belt 24. A conveyor motor 10 is located on the right side of the front side of the housing 1, and the input end of the conveyor motor 10 is electrically connected to the output end of the controller 11. An extension plate 4 is located on the upper right side of the hopper 3, and an air duct 8 is located on the right side of the discharge hopper 7. The height of the air duct 8 is lower than that of the hopper 3. A blower is installed on the lower surface of the hopper 3 and the lower side of the air duct 8. The input end of the blower is electrically connected to the output end of the controller 11. When the hopper 3 moves along the transmission direction of the conveyor belt 24 and cuts into the air duct 8, the upper surface of the air duct 8 maintains a sliding relationship with the receiving extension plate 4. Therefore, the lower hopper 3 forms a relatively closed channel with the side wall of the casing 1 through the receiving extension plate 4. This channel is the pneumatic conveying channel for powder. At this time, the controller 11 can be adjusted to operate the toggle motor and the conveyor motor 10. The rotation of the output shaft of the toggle motor will cause the toggle plate 6 to rotate, continuously feeding the powder in the feed hopper 5 into the hopper 3. The output shaft of the conveyor motor 10 rotates, thereby driving the transmission wheel 22 on the right side to rotate. The conveyor belt 24 then drives the left-side drive wheel 22 to rotate. During the operation of the conveyor belt 24, the fixed blocks 25 on the conveyor belt 24 move along the transmission direction of the conveyor belt 24. When the fixed seats 29, which are in pairs, move to the left side of the inside of the housing 1, they are tilted in the circular direction of the left-side drive wheel 22. At this time, the left fixed seat 29 in the pair of fixed seats 29 tilts first along the circular tilt direction of the drive wheel 22. The hopper 3 will then be affected by the tilt and tilt to the left, thus dumping the powder in the hopper 3. Due to the sealing effect of the extension plate 4, a large amount of powder is effectively prevented from being dumped onto the conveyor belt 24. Instead, the powder will fall into the next hopper 3 first.Then, as the hopper 3 moves along the transmission direction of the conveyor belt 24, the powder is discharged through the discharge hopper 7. Simultaneously, the controller 11 can be adjusted to activate the induced draft fan, which draws external airflow into the casing 1 through the induced draft channel 8. This airflow is ejected from the lower part of the casing 1, performing high-pressure cleaning on the inside of the hopper 3 passing through the right side of the casing 1. The resulting material undergoes secondary pneumatic conveying along the transmission direction of the conveyor belt 24 and is then discharged outside the casing 1 through the discharge hopper 7.

[0027] The working principle of the powder material conveying mechanism provided by this utility model is as follows: When the conveying mechanism is needed, the external powder material can be fed into the inside of the housing 1 through the feed hopper 5. At this time, the controller 11 can be adjusted to operate the toggle motor and the conveyor motor 10. The output shaft of the toggle motor rotates, which drives the toggle plate 6 to rotate, continuously feeding the powder material in the feed hopper 5 into the hopper 3. The output shaft of the conveyor motor 10 rotates, which in turn drives the right transmission wheel 22 to rotate, which in turn drives the left transmission wheel 22 to rotate through the conveyor belt 24. During the operation of the conveyor belt 24, the fixed blocks 25 on the conveyor belt 24 can be moved along the transmission direction of the conveyor belt 24. When the fixed seats 29, which are in groups of two, move to the left side of the inside of the housing 1, they are subject to the circular tilting direction of the left transmission wheel 22. At this time, the fixed seats 29, which are in groups of two, move along the transmission direction of the conveyor belt 24. The left fixed seat 29 in seat 29 first tilts along the circular tilt direction of the transmission wheel 22. At this time, the hopper 3 will be affected by the tilt and tilt to the left, which will cause the powder in the hopper 3 to be poured out. Due to the sealing effect of the extension plate 4, the powder is effectively prevented from being poured out of the conveyor belt 24 in large quantities. Instead, it will fall into the next hopper 3 first. Then, as the hopper 3 moves along the transmission direction of the conveyor belt 24, the powder will be discharged with the discharge hopper 7. At the same time, the controller 11 can be adjusted to start the blower. The blower will bring the external airflow into the housing 1 along the blower channel 8. This airflow is sprayed out in the lower part of the housing 1 and blows the inside of the hopper 3 on the right side of the housing 1 under high pressure to complete the cleaning. The material generated is conveyed pneumatically along the transmission direction of the conveyor belt 24 and then discharged out of the housing 1 with the discharge hopper 7.

[0028] It is worth noting that the core chip of the controller 11 disclosed in the above embodiments is a PLC microcontroller, specifically the STM32. The toggle motor, conveyor motor 10, and induced draft fan can be freely configured according to the actual application scenario. It is recommended to use the S37RF17DE71M4 combined high-torque geared motor for the toggle motor, the Y-series three-phase AC asynchronous motor for the conveyor motor 10, and the GDF series centrifugal duct fan for the induced draft fan. The controller 11 controls the operation of the toggle motor, conveyor motor 10, and induced draft fan using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
