Technical Field

[0001] The utility model belongs to the technical field of powder material batching, and in particular relates to an automatic powder material batching device. Background Art

[0002] Powder refers to a substance composed of fine particles. Common powders include but are not limited to flour, cement, plastic powder, medicinal powder, etc. Powder is widely used in food processing, chemical industry, pharmaceutical industry, building materials and other fields. The automatic powder batching device is a mechanical equipment used to automatically measure, weigh and mix different types of powders. This device is widely used in chemical industry, food, pharmaceutical industry, building materials and other industries to ensure that powders are mixed in precise proportions during the production process to achieve the required product quality and performance.

[0003] The existing automatic powder batching device drives the internal scattering piece by a motor to scatter the internal powder and discharge the powder through the cooperation of the spiral feeding piece and the discharge pipe. However, when the spiral feeding piece cooperates with the discharge pipe to discharge the powder, the powder will be squeezed and agglomerated, resulting in the discharge of the powder agglomerates. The agglomerated powder will cause uneven mixing in subsequent production, affecting the quality and performance of the final product. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides an automatic powder batching device that can quickly break up the powder that is squeezed and agglomerated when discharged from the spiral conveying plate and the discharge pipe, making the subsequent production mixing more uniform and improving the quality of the final product.

Yuan 1 includes two motors 1 respectively arranged at the upper end of the material box, and the upper ends of the two motors 1 are respectively connected to the upper ends of adjacent rotating columns, and the re-scattering mechanism includes a frame plate arranged inside the lower end of the mounting frame, and connecting plates are respectively provided on the left and right sides of the inner wall of the frame plate, and the frame plate and the connecting plate are fixed by welding. Two guide columns are slidably provided inside the two connecting plates, and a scattering plate is slidably provided between the outer arc surfaces of the four guide columns, and multiple springs are provided between the scattering plate and the connecting plate, and the multiple springs are respectively sleeved on the outer arc surfaces of the corresponding guide columns. A rotating column is provided for rotation inside the frame plate, and two cams are fixedly sleeved on the outer arc surface of the rotating column. The rotating column and the cam are fixed by welding, and the two cams are cooperated with the lower end of a frame plate. An electric drive unit 2 for driving the rotating column to rotate is provided on the left side of the frame plate. The electric drive unit 2 includes motor 2 arranged on the left side of the frame plate, and the output shaft of motor 2 is connected to the left end of the rotating column through a coupling.

[0006] As a further improvement of the present invention, a control panel is provided inside the mounting frame, and both the first motor and the second motor are electrically connected to the control panel.

[0007] As a further improvement of the present invention, mounting plates are respectively provided on the left and right sides of the lower end of the mounting frame, and two mounting holes are provided inside the two mounting plates.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] First, by controlling the handle to pull the protective plate, different types of powder can be added into the interior of the two material boxes through the feed shell, which can prevent the powder from overflowing from the interior of the material box when the powder is subsequently dosed.

[0010] Secondly, by controlling and turning on the operation of the motor 1 on the left side, the output shaft drives the spiral feed piece at the lower end of the rotating column to rotate and realizes the discharge of the powder with the cooperation of the discharge pipe. At the same time, the scattering piece on the rotating column rotates to break up the agglomerated powder, making the feeding process of the spiral feed piece smoother. The personnel can judge that the internal powder is discharged to the specified batching height through the scale on the scaled observation window, and then turn off the operation of the motor 1 on the left side. Similarly, by controlling the motor 1 on the right side, the powder inside the right material box can be discharged and batched. Due to the influence of gravity, the powder falls onto the scattering plate inside the frame plate, which can quickly realize the automatic batching of the powder.

[0011] Thirdly, by controlling the operation of motor 2, the output shaft drives the cam on the rotating column to rotate, and the cam rotates to contact the scattering plate. At this time, the spring is in a stretched state. After the cam rotates out of the contact range with the scattering plate, the scattering plate will move downward under the action of the spring rebound force and the guide column, causing the scattering plate to vibrate up and down, and the powder that is agglomerated on the scattering plate due to the squeezing of the spiral conveying plate and the discharge pipe is quickly broken up by vibration, ensuring that the subsequent powder production mixing is more uniform, and the powder that is squeezed and agglomerated when the spiral conveying plate and the discharge pipe are discharged can be quickly broken up, making the subsequent production mixing more uniform and improving the quality of the final product.

[0012] Fourthly, the batching device can be quickly installed in a suitable position through the mounting holes on the mounting plate, so that it can be quickly put into production. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the material box 104 is provided with an electric drive unit 1 for driving the rotating column 202 to rotate, and the electric drive unit 1 includes two motors 201 respectively provided at the upper end of the material box 104, and the upper ends of the two motors 201 are respectively connected to the upper ends of the adjacent rotating columns 202.

[0021] As shown in Figures 1, 3 and 4, the re-dispersing mechanism includes a frame plate 301 arranged inside the lower end of the mounting frame 101, and connecting plates 306 are respectively provided on the left and right sides of the inner wall of the frame plate 301.

A plurality of springs 305 are provided between the dispersing plate 302 and the connecting plate 306, and the plurality of springs 305 are respectively sleeved on the outer arc surfaces of the corresponding guide posts 304. A rotating post 307 is rotatably provided inside the frame plate 301, and two cams 308 are fixedly sleeved on the outer arc surface of the rotating post 307. The two cams 308 are mounted on the lower end of a frame plate 301. An electric drive unit 2 for driving the rotating post 307 to rotate is provided on the left side of the frame plate 301.

[0023] By controlling the handle to pull the protective plate, different types of powder can be added into the two material boxes 104 through the feed shell 106 respectively.
