The dispersing mechanism 2 is used to facilitate the smooth falling of the powder. The conveying assembly includes a third motor 15. The output end of the third motor 15 passes through the conveying pipe 14 and is fixedly connected to a rotating column 16. The outer side of the rotating column 16 is fixedly connected to a spiral blade 17.

[0040] Specifically, when the powder needs to be conveyed, the bag containing the powder is first placed between the first fixed plate 11 and the second fixed plate 12, and then the first motor 4 starts to start. The start of the first motor 4 will drive the rotating rod 5 connected thereto to rotate. During the rotation of the rotating rod 5, the two active bevel gears 6 on its outer side also rotate accordingly. Since the driven bevel gear 8 and the active bevel gear 6 are meshed with each other, the two driven bevel gears 8 are driven by the active bevel gear 6 to rotate, and since the two threaded rods 7 are connected to the same sliding plate 28, the sliding plate 28 will move accordingly. At the same time, the knife seat 9 located on the top of the sliding plate 28 also moves with the movement of the sliding plate 28, and the cutter 10 installed on the knife seat 9 will also move therewith.

[0041] Reference Figure 2 、 Figure 4 and Figure 5 The dispersion mechanism 2 includes a grille 201, which is fixedly connected to the middle and lower part of the inner side of the hollow box 1. The second motor 202 is fixedly connected to the left bottom of the hollow box 1. The output end of the second motor 202 passes through the hollow box 1 and is fixedly connected to a transmission rod 203.

Gear 206, the two half gears 206 are respectively meshed with the corresponding flat gear 204, the tops of the two half gears 206 are fixedly connected to the connecting rod 207, the tops of the two connecting rods 207 are fixedly connected to the knocking balls 208, the top of the hollow box 1 is fixedly connected to the fixed block 18, the top of the fixed block 18 is fixedly connected to the dust suction fan 19, the bottom of the dust suction fan 19 is connected to the suction pipe 20, the bottom end of the suction pipe 20 passes through the fixed block 18 and the hollow box 1 in sequence;

[0042] Specifically, during the use of the device, when the dust gradually falls from the bag, it will first pass through the grille 201. In order to ensure the smooth flow of the grille 201, the second motor 202 will start automatically. The start of the second motor 202 will drive the transmission rod 203 to rotate. During the rotation of the transmission rod 203, the flat gears 204 on both sides will also start to rotate. Since the half gear 206 is engaged with the flat gear 204, when the two flat gears 204 rotate, the two half gears 206 will be driven to rotate accordingly. The rotation of the half gear 206 will further drive the connecting rod 207 to rotate. The rotational movement of the connecting rod 207 will eventually drive the knocking ball 208 to knock on the grille 201. This knocking action can effectively prevent dust from agglomerating and clogging the grille 201, thereby refining the powder, improving the conveying efficiency of the device, and the powder dispersed in the hollow box 1 can be collected by the dust suction fan 19.

[0043] Reference Figure 1 A support frame 21 is fixedly connected to the middle and lower part of the outer side of the hollow box 1, and gaskets 22 are fixedly connected to the four corners of the bottom of the support frame 21. A box door 24 is provided on the front side of the hollow box 1. Hinges 25 are fixedly connected to the upper and lower sides of the left end of the front wall of the box door 24. The box door 24 is rotatably connected to the hollow box 1 through the hinges 25. An observation window 26 is opened in the middle and upper part of the front side of the box door 24;

[0044] Specifically, by driving screws into the gasket 22, the gasket 22 can be fixed to the ground, thereby firmly fixing the support frame 21, and the box door 24 can prevent dust from leaking out of the box when the device is working, and the working conditions inside the device can be observed through the observation window 26.

The controller 27 is electrically connected to the first motor 4, the third motor 15 and the second motor 202 respectively;

[0046] Specifically, the operating panel 23 facilitates the staff to move the bags containing powder. The inner size of the hollow box 1 matches the size of the grid 201, so that the powder will not enter the gap between the grid 201 and the hollow box 1, and the controller 27 can control the operation of the first motor 4, the third motor 15 and the second motor 202 respectively. The models of the first motor 4 and the second motor 202 are MS8012, and the model of the third motor 15 is YRKK800.

[0047] Working principle: When the powder needs to be conveyed, the bag containing the powder is first placed between the first fixed plate 11 and the second fixed plate 12, and then the first motor 4 is started. The first motor 4 will drive the rotating rod 5 to rotate. When the rotating rod 5 rotates, the two active bevel gears 6 on its outer side will rotate accordingly. Since the driven bevel gear 8 is meshed with the active bevel gear 6, the two driven bevel gears 8 will drive the two threaded rods 7 to rotate. Since the two threaded rods 7 are connected to the same sliding plate 28, the sliding plate 28 will move when the two threaded rods 7 rotate. At this time, the knife seat 9 on the top of the sliding plate 28 will drive the cutter 10 to move. When the cutter 10 moves, it can cut the bag containing the powder, and the powder will be scattered from the bag and fall into the conveying pipe 14 through the hollow cone 13. At this time, the third motor 15 is started and drives the rotating column 16 to rotate, and the spiral blade 17 rotates accordingly, which can carry out the powder conveying work. The staff only needs to put the bag containing the powder into the device to complete the conveying work, which reduces the leakage when dumping the powder.

[0048] When the device is in use, dust falls from the bag and passes through the grille 201. At this time, the second motor 202 is started, and the start of the second motor 202 will drive the transmission rod 203 to rotate. When the transmission rod 203 rotates, the flat gears 204 on both sides thereof will rotate accordingly. Because the half gear 206 is meshed with the flat gear 204, when the two flat gears 204 rotate, the two half gears 206 will rotate accordingly. When the two half gears 206 rotate, they will drive the two connecting rods 207 to rotate. At this time, when the two connecting rods 207 rotate, they will drive the knocking balls 208 to knock on the grille 201, which can prevent the agglomerated dust from clogging the grille 201. The device can refine the powder so that it will not agglomerate and cause clogging.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
