[0002] A dust purifier is a type of equipment widely used in grain processing, food industry, chemical industry and other fields. It is mainly used to separate impurities and dust from materials. The working principle of a dust purifier is usually to separate light impurities from heavy materials through the action of airflow. The air chamber and air damper are key components of the dust purifier, which are responsible for adjusting the speed and direction of airflow, thereby affecting the separation effect of materials.

[0003] The damper adjustment structure of the air chamber in the powder cleaning machine is a key component for controlling the size and direction of airflow, which directly affects the separation effect of materials and the operating efficiency of the equipment. Different impurity materials require different airflow sizes, and if the damper adjustment is inconvenient, the exhaust volume cannot be flexibly adjusted according to the characteristics of the materials and the working conditions, which may lead to unstable separation effect.

[0004] Therefore, to address the problems of inconvenient adjustment of the exhaust volume and inconvenience in filtering the input air, a damper adjustment structure for the air chamber of a powder cleaning machine is needed to solve these problems. Utility Model Content

[0005] To address the problems of inconvenient adjustment of exhaust volume and inconvenience in filtering input air in existing technologies, this application provides an air chamber damper adjustment structure for a powder cleaning machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A damper adjustment structure for a powder cleaning machine air chamber includes: a device body, a fixed frame fixedly connected to the left end of the device body, a connecting plate connected to the bottom end of the inner wall of the fixed frame via a transmission assembly, a plurality of engaging grooves opened on the outer wall of the connecting plate, a closing plate connected to the inner wall of the engaging grooves via a deflection assembly, the transmission assembly including an electric push rod fixedly connected to the front side of the bottom end of the fixed frame, and the bottom end of the connecting plate fixedly connected to the driving end of the electric push rod;

[0008] A connecting frame is fixedly connected at its top to the top of the inner wall of the device body. A drive motor is fixedly connected to the inner wall of the front end of the connecting frame. The drive end of the drive motor is connected to a transmission block via a moving assembly. A cleaning brush is rotatably connected to the rear end of the transmission block. A toothed plate is connected to the cleaning brush via a driven assembly. The deflection assembly includes an adapter rod fixedly connected to the front end of the closing plate. The front end of the adapter rod is sleeved on the inner wall of the fitting groove. The rear end of the closing plate is rotatably connected to the inner wall of the fixed frame.

[0009] As a further improvement of this utility model, a controller is installed at the front end of the device body, and a scale groove is provided on the outer wall of the front end of the device body opposite to the outside of the controller.

[0010] As a further improvement of this utility model, the moving assembly includes a reciprocating lead screw fixedly connected to the drive end of the drive motor, and a slider is sleeved on the outer wall of the reciprocating lead screw.

[0011] As a further improvement of this utility model, the outer wall of the slider is fixedly connected to the inner wall of the transmission block, and the outer wall of the transmission block is slidably connected to the inner wall of the front end of the connecting frame.

[0012] As a further improvement of this utility model, the driven assembly includes a transmission gear fixedly connected to the rear end of the cleaning brush, and the toothed plate and the transmission gear are meshed together.

[0013] As a further improvement of this utility model, a dust filter is installed on the left end of the connecting frame, and the outer wall of the dust filter is in close contact with the outer wall of the cleaning brush.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, when the electric push rod is started, it drives the connecting plate to move. When the connecting plate moves in the slide groove, the closing plate is deflected by the adapter rod, thereby changing the opening and closing angle of the closing plate at the fixed frame, reducing the gap between the closing plate and the fixed frame, reducing the exhaust volume of the device, and making it convenient for the device to adjust the airflow according to the required airflow of the impurity material.

[0016] 2. In this utility model, when the reciprocating screw is driven to rotate by the drive motor, the reciprocating screw drives the transmission block to move along the connecting frame through the slider. This causes the transmission block to drive the cleaning brush and the transmission gear to move along the tooth plate. This facilitates the rotation of the cleaning brush during the movement, thereby effectively cleaning the dust filter, maintaining the cleanliness of the dust filter and the ventilation flow, and preventing impurities from clogging the dust filter.

[0030] Example 1: A damper adjustment structure for a powder cleaning machine's air chamber, comprising: a device body 1, a fixed frame 2 fixedly connected to the left end of the device body 1, a connecting plate 8 connected to the bottom of the inner wall of the fixed frame 2 via a transmission, a plurality of engaging grooves 9 formed on the outer wall of the connecting plate 8, a connecting rod 11 fixedly connected to the front end of a closing plate 5, the front end of the connecting rod 11 sleeved on the inner wall of the engaging grooves 9, and the rear end of the closing plate 5 rotatably connected to the inner wall of the fixed frame 2. In the damper adjustment structure for the powder cleaning machine's air chamber, the controller 3 aligns with the indicator mark at the scale groove 4. The electric push rod 10 and the drive motor 12 can be adjusted accordingly. When the electric push rod 10 is started, it will drive the connecting plate 8 to move. When the connecting plate 8 moves in the slide groove 9, it will cause the closing plate 5 to deflect through the adapter rod 11, thereby changing the opening and closing angle of the closing plate 5 at the fixed frame 2. The deflection of the closing plate 5 will reduce the gap between the closing plate 5 and the fixed frame 2, thereby reducing the exhaust volume of the device. The powder cleaner can be adjusted according to the airflow required by the impurity material to ensure the best separation effect.

[0031] Example 2: Connecting frame 6, the top of connecting frame 6 is fixedly connected to the top of the inner wall of the device body 1, the front inner wall of connecting frame 6 is fixedly connected to drive motor 12, the drive end of drive motor 12 is fixedly connected to reciprocating lead screw 13, the outer wall of reciprocating lead screw 13 is sleeved with slider 15, the rear end of transmission block 14 is rotatably connected to cleaning brush 16, the rear end of cleaning brush 16 is fixedly connected to transmission gear 18, the toothed plate 17 and transmission gear 18 are meshed. In the dust filter cleaning mechanism of the dust cleaning machine air chamber, when drive motor 12 drives reciprocating lead screw 13 to rotate, reciprocating lead screw 13 drives transmission block 14 to move in connecting frame 6 through slider 15. The movement of transmission block 14 drives cleaning brush 16 at the same time, so that transmission gear 18 moves along toothed plate 17, so that cleaning brush 16 rotates during the movement, thereby effectively cleaning dust filter 7, maintaining the cleanliness of dust filter 7 and smooth ventilation, and avoiding impurities clogging dust filter 7.

[0032] As one of the optimized structural designs for Example 1, such as Figures 1-4 As shown, copying from the right + sentence expansion

[0033] Working principle: The controller 3 aligns with the scale groove 4 to adjust the electric push rod 10 and drive motor 12 accordingly. When the electric push rod 10 is started, it drives the connecting plate 8 to move. When the connecting plate 8 moves, it engages with the sliding groove 9, which drives the adapter rod 11 to deflect the closing plate 5. This changes the opening and closing angle of the closing plate 5 at the fixed frame 2, reducing the gap between the closing plate 5 and the fixed frame 2, thus reducing the exhaust volume of the device. This allows the device to adjust the airflow according to the required amount of impurities. When the drive motor 12 drives the reciprocating screw 13 to rotate, the reciprocating screw 13 drives the transmission block 14 to move along the connecting frame 6 via the slider 15. This causes the transmission block 14 to drive the cleaning brush 16, which in turn causes the transmission gear 18 to move along the toothed plate 17. This allows the cleaning brush 16 to rotate during the movement, thus cleaning the dust filter 7, maintaining the cleanliness of the dust filter 7, ensuring the ventilation flow of the dust filter 7, and preventing impurities from clogging the dust filter 7.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
