[0038] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0039] like Figure 1 、 2 As shown, an embodiment of the present invention discloses a vacuum conveying device for powder, comprising a shell 1, a feeding mechanism 2 is provided at the top end of the shell 1, a discharging mechanism 3 is provided at the bottom end of the shell 1, a partition mechanism 4 is provided in the shell 1, and the partition mechanism 4 includes a partition rod 41 provided in the shell 1, the partition rod 41 is an inverted V-shape, and a V-shaped cavity is formed on the lower side of the partition rod 41, and a vacuum hole 42 is provided on the side wall of the V-shaped cavity, and a vacuum pump is provided in communication with the vacuum hole 42.

[0040] Specifically, when in use, the feeding mechanism 2 is opened and the powder is transported into the feeding mechanism 2. After the powder enters, the feeding mechanism 2 is closed. A plurality of partition rods 41 are provided in the shell 1. Due to the inverted V-shaped setting of the partition rods 41, the V-shaped cavity is not filled with powder. Then the vacuum pump is started, and the vacuum pump vacuums the powder in the shell 1 through the vacuum hole 42. After the vacuuming is completed, the discharging mechanism 3 is opened, and the powder is discharged from the discharging mechanism 3 to the shell 1.

[0041] By setting the partition rod 41, after the powder enters the shell 1, a cavity can be formed on the lower side of the partition rod 41, which makes it convenient for the vacuum pump to vacuum the powder through the vacuum hole 42, and at the same time facilitates the flow of gas in the powder, reducing the time and power required for vacuuming.

[0042] Furthermore, the vacuum pump is a prior art and will not be described in detail.

[0043] like Figure 8 As shown, a first installation cavity 43 and a second installation cavity 44 are provided in the shell 1. The first installation cavity 43 and the second installation cavity 44 are respectively located at the two ends of the partition rod 41. The vacuum hole 42 is connected to the first installation cavity 43. The vacuum pump is connected to the first installation cavity 43. A solenoid valve and a filter are provided in the vacuum hole 42.

[0044] Specifically, when vacuuming is required during use, the solenoid valve is opened and the vacuum pump is started at the same time. The vacuum pump sucks the gas in the first installation cavity 43 and simultaneously sucks the gas in the powder in the shell 1 through the vacuum hole 42 .

[0045] Through the setting of the solenoid valve and the filter, during the vacuum process, the powder is sucked by the vacuum pump, affecting the normal transportation of the powder and the normal operation of the vacuum pump.

[0046] Furthermore, the solenoid valve is a prior art and will not be described in detail.

[0047] like Figure 3 、 5 As shown in , 6 and 9, a rotating part 45 is provided in the first installation cavity 43, and the rotating part 45 includes a hollow tube 451 rotatably arranged in the vacuum hole 42, one end of the hollow tube 451 is fixedly connected to the dividing rod 41, and the other end of the hollow tube 451 extends into the first installation cavity 43, the solenoid valve and the filter are located in the hollow tube 451, and the end of the hollow tube 451 extending into the first installation cavity 43 is fixedly sleeved with an impeller 452, and a first torsion spring 453 is connected between the impeller 452 and the side wall of the first installation cavity 43, and an air blowing pipe 454 is provided in the first installation cavity 43, and an air hole 455 is opened on the air blowing pipe 454, and the opening of the air hole 455 is inclined toward the impeller 452, and the air blowing pipe 454 is connected to a gas pump.

[0048] Specifically, during use, when the powder enters the shell 1, the gas pump is started, and the air pump supplies gas into the air pipe 454, and then the gas is discharged from the air hole 455 in the air pipe 454, and the gas is blown onto the impeller 452, driving the impeller 452 to rotate, the impeller 452 drives the hollow tube 451 to rotate, and the hollow tube 451 drives the dividing rod 41 to rotate, and at the same time the impeller 452 stores force on the first torsion spring 453. When the dividing rod 41 rotates, the powder in the shell 1 is stirred, so that the powder in the shell 1 is dispersed more evenly, and at the same time, the powder has a certain stirring and crushing effect, reducing the agglomeration of the powder; then the air pump is stopped, and the impeller 452 rotates in the opposite direction under the action of the first torsion spring 453, and the powder is dispersed and crushed again; in this way, the air pump is continuously started and stopped to disperse and crush the powder.

[0049] By setting the rotating member 45, the rotating member 45 can drive the dividing rod 41 to rotate, so that the dividing rod 41 disperses and breaks the powder, making the powder more evenly dispersed in the shell 1, and can reduce powder agglomeration, which is conducive to vacuuming the powder.

[0050] Furthermore, the gas pump is a prior art and will not be described in detail.

[0051] like Figure 4 、 9 As shown in Figure 10, the partition mechanism 4 also includes an auxiliary part 46, and the auxiliary part 46 includes an auxiliary plate 461.

The auxiliary plate 461 is provided with three downward-opening mounting grooves 462 at equal intervals. The mounting groove 462 is rotatably connected to an end away from the rotating part 45 with a stirring rod 463. A second torsion spring is connected between the stirring rod 463 and the side wall of the mounting groove 462, and the stirring rod 463 can enter the mounting groove 462. An entry groove 464 is provided on the side wall of the shell 1, and the entry groove 464 is connected to the second mounting cavity 44. The auxiliary plate 461 can enter the entry groove 464.

[0052] Specifically, during use, when the partition rod 41 rotates, the partition rod 41 drives the auxiliary plate 461 to rotate, and the auxiliary plate 461 drives the stirring rod 463 to rotate, and the stirring rod 463 and the partition rod 41 jointly stir the powder.

[0053] By setting the auxiliary member 46, when the partition rod 41 rotates, it can drive the auxiliary plate 461 and the stirring rod 463 to rotate, and cooperate with the partition rod 41 to stir the powder, so as to achieve a better dispersion and crushing effect on the powder.

[0054] like Figure 8 、 10As shown, the auxiliary part 46 also includes a magnetic plate 465 slidably arranged in the entry slot 464, and the magnetic plate 465 can be magnetically attracted to the auxiliary plate 461. The magnetic plate 465 extends out of the shell 1 in a direction away from the rotating part 45, and the extended end of the magnetic plate 465 is fixedly connected to a movable plate 466, and the movable plate 466 can move in a direction away from the shell 1.

[0055] Specifically, during use, when vacuuming is required, the movable plate 466 is moved, and the movable plate 466 moves in the direction away from the shell 1. The movable plate 466 drives the auxiliary plate 461 to move through magnetic force, and the auxiliary plate 461 drives the stirring rod 463 to move. When the stirring rod 463 abuts against the edge of the entry groove 464, the stirring rod 463 flips upward and enters the installation groove 462. When the auxiliary plate 461 is removed from the V-shaped cavity, the movement of the movable plate 466 is stopped, and at the same time, the auxiliary plate 461 closes the entry groove 464.

[0056] By setting the magnetic plate 465, when the partition plate 41 and the auxiliary plate 461 rotate, the magnetic plate 465 will close the entry groove 464. At the same time, when the magnetic plate 465 moves, it can drive the auxiliary plate 461 to move, making it convenient to vacuum the powder.
