[0025] See also Figure 1 , an automatic weighing and packaging device in this embodiment is used to weigh and package glitter powder.

[0026] Specifically, it includes a support frame 1, a lower hopper 2, a weighing device 3 and a packaging mechanism 4; the lower hopper 2 is installed inside the support frame 1 to store the glitter powder therein; the weighing device 3 includes a carrying plate 301 and a pressure sensor 302; the carrying plate 301 is installed on the front side of the support frame 1, and the carrying plate 301 is arranged on the carrying plate 301 to calculate the weight of the loaded glitter powder; the packaging mechanism 4 is arranged on the support frame 1 to package the packaging bags of the glitter powder.

[0027] In actual use, the packaging bag is placed on the end of the lower hopper 2 to transport the glitter powder inside the lower hopper 2 to the inside of the packaging bag. The weight of the glitter powder inside the packaging bag is calculated by the pressure sensor 302. When the weight of the glitter powder inside the packaging bag reaches the required value, the packaging bag is packaged by the packaging mechanism 4.

[0028] It should be noted that, in order to facilitate supporting the packaging bag loaded with glitter powder, the carrying plate 301 is vertically distributed to the front side of the support frame 1 , and the pressure sensor 302 is located directly below the end of the lower hopper 2 .

[0029] See also Figure 2-3In order to facilitate the packaging process of the packaging bag, the packaging mechanism 4 in this embodiment includes at least two first driving rods 401, at least two second driving rods 402 and at least two electric heating clamps 403; at least two first driving rods 401 and at least two second driving rods 402 are all connected to the front side of the inner wall of the support frame 1, and at least two electric heating clamps 403 are respectively installed on the outside of the first driving rods 401 and the second driving rods 402 for sealing the packaging bag.

[0030] In actual use, the packaging bag is passed between the two electric heating clamps 403. When the packaging bag needs to be packaged, the two electric heating clamps 403 are controlled to move toward each other so that the two electric heating clamps 403 are in contact with the two sides of the packaging bag respectively, thereby heating the two sides of the packaging bag to soften it, and then the two sides of the packaging bag are attached together to seal the packaging bag.

[0031] Furthermore, in order to improve the sealing efficiency of both sides of the packaging bag, at least two electric heating clamps 403 in this embodiment are provided with serrated teeth grooves facing each other.
