[0032] The interior of the hopper 6 is fixedly connected with two arc-shaped plates 14 , and the interior of the feed pipe 9 is fixedly connected with two arc-shaped plates 2 15 .

[0033] The shielding assembly includes a mounting frame 16 fixedly connected to the outside of the hopper 6, one side of the inner wall of the mounting frame 16 is fixedly connected to an electric telescopic rod 17, one end of the electric telescopic rod 17 is fixedly connected to a shielding plate 18, one side of the shielding plate 18 penetrates into the interior of the hopper 6 and is located below the hollow ring 7, the opposite sides of the two arc plates 14 are respectively fitted with the two sides of the shielding plate 18, and one side of the shielding plate 18 is arc-shaped and fits with the inner wall of the hopper 6.

[0034] The shielding component 2 includes a mounting frame 219 fixedly connected to the outside of the feed pipe 9, and an electric telescopic rod 20 is fixedly connected to one side of the inner wall of the mounting frame 19. One end of the electric telescopic rod 20 is fixedly connected to a shielding plate 21.

[0037] An alarm 26 is installed on the surface of the workbench 1 , and the alarm 26 is electrically connected to the controller 2 .

[0038] Working principle: when it is necessary to add raw materials to the lower mold 3, the electric telescopic rod 17 is started to drive the shielding plate 18 to move inward, so that the discharge port of the hopper 6 is not blocked, so that the powder in the hopper 6 can enter the feeding frame 5 through the hopper 6. After a period of time, the electric telescopic rod 17 is started and contracted to block and clean the discharge port of the hopper 6. Then the hydraulic rod 24 is started to push the sealing plate 25, so that the sealing plate 25 pushes the powder inside the feeding frame 5 into the lower mold 3. Since the inner wall of the feed hole 4 is tightly fitted with the discharge port of the feed frame 5, the feed hole 4 can be sealed by the sealing plate 25 after the feeding is completed. Then the hydraulic rod 24 is started to move the upper mold 23 down to the lower mold 3 and pressurize the powder inside it. After the powder is pressurized, the sealing plate 25 returns to its original position to continue pushing the feeding.

[0039] When the powder inside the hopper 6 is insufficient, the pressure sensor 8 senses that the weight of the powder above the hollow ring 7 is unqualified, and the pressure sensor 8 transmits the pressure signal to the controller 2 and is received by the controller 2. After receiving the signal, the controller 2 starts the electric telescopic rod 20 to contract so that the feed pipe 9 is not blocked, so that the powder in the storage box 13 enters the hopper 6 from the feed pipe 9 until the pressure sensor 8 senses that the weight of the powder above the hollow ring 7 is qualified. At this time, the pressure sensor 8 transmits the pressure signal to the controller 2 and is received by the controller 2. After receiving the signal, the controller 2 starts the electric telescopic rod 20 to extend again to block the feed pipe 9, thereby automatically completing the feeding work of the hopper 6;

[0040] When the powder inside the storage box is insufficient, the pressure sensor 11 senses that the weight of the powder above the hollow ring 10 is unqualified. At this time, the pressure sensor 11 transmits the pressure signal to the controller 2 and the controller 2 receives it. After receiving the signal, the controller 2 activates the alarm 26 to alarm, thereby reminding the staff to add powder to the storage box.
