[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-5 , an automatic packaging machine for pre-dispersed particles, including a hopper 1, a screen 2 is arranged in the hopper 1, several legs 3 are connected to the hopper 1, the same top plate 4 is connected to several legs 3, a first motor 5 is arranged on the top plate 4, the bottom end of the output end of the first motor 5 is connected to a rotating shaft 6, the rotating shaft 6 is located in the hopper 1, a scraper 7 is arranged at the bottom end of the rotating shaft 6, the scraper 7 is located on the screen 2 and is in contact with the screen 2, the bottom end of the hopper 1 is connected to a housing 8, a second motor 9 is arranged at the bottom end of the housing 8, the output end of the second motor 9 is connected to a rotating disk 10, several dividing chambers 11 with the same specifications are arranged on the rotating disk 10, the dividing chambers 11 are arranged in a circular pattern, each dividing chamber 11 can respectively correspond to the discharge port of the hopper 1, a plug rod 12 is slidably connected to the top end inside the housing 8, a connecting plate 13 is connected to the top end of the plug rod 12, a spring 14 is connected between the connecting plate 13 and the housing 8, one side of the plug rod 12 located inside the housing 8 is beveled, and a feeding pipe 15 is connected to the bottom end of the housing 8 corresponding to the position of the plug rod 12.

[0023] Through the setting of the screen 2, the pre-dispersed particles can be effectively screened, preventing larger-sized particles from mixing in, reducing the difference range of the particle sizes between the packaged particles, thereby reducing the deviation in quantitative packaging. And by driving the rotating shaft 6 to rotate by the first motor 5, the scraper 7 drives away the large-sized particles staying on the screen 2, preventing the problem of screen clogging. Through the cooperation between the plug rod 12, the connecting plate 13 and the spring 14, when the second motor 9 drives the rotating disk 10 to rotate, the plug rod 12 can automatically extend and rebound according to the position of the dividing chamber 11, preventing the discharge of the dividing chamber 11 from being blocked. And compared with the prior art method of using a cylinder to drive the discharge, this structure reduces the cylinder driving time and effectively improves the packaging efficiency.

[0024] Specifically, in this embodiment, the legs 3 are inclined, and the outer diameter of the top plate 4 is smaller than the inner diameter of the hopper 1, providing a larger space for loading the pre-dispersed particles into the hopper 1.

[0025] Specifically, in this embodiment, several groups of stirring rods 16 arranged axially are connected to the outer wall of the rotating shaft 6. Driven by the rotating shaft 6, the stirring rods 16 perform circular motion to agitate the unpre-dispersed particles in the hopper 1 that have not been screened, which is beneficial to the falling and dispersion of the particles.

[0026] Specifically, in this embodiment, a material removal opening 17 is provided on the outer wall of the hopper 1 located on the top surface of the screen 2, which facilitates the removal of the large-sized particles after screening from the hopper 1.

[0027] Specifically, in this embodiment, a movable door 18 is provided at the material removal opening 17 of the hopper 1. When the movable door 18 closes the material removal opening 17, it prevents the particles from flowing out.

[0028] Specifically, in this embodiment, a connecting shaft 19 is connected to the bottom end of the scraper 7. The connecting shaft 19 penetrates through the screen 2. A brush 20 is connected to the outer wall of the connecting shaft 19 below the screen 2. The brushing surface of the brush 20 contacts the bottom end of the screen 2. When the scraper 7 rotates, through the connection of the connecting shaft 19, the brush 20 performs circular motion, so as to push out the particles blocked in the holes of the screen 2 from bottom to top, further preventing the problem of blockage of the screen 2.

[0029] Specifically, in this embodiment, the thickness of the rotating disk 10, the depth of the material distribution cavity 11 and the depth of the inner cavity of the housing 8 are all the same, which prevents the unpre-dispersed particles from being flushed into the gap between the rotating disk 10 and the housing 8 and ensures the unity of the quantitative packaging.
