[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] This utility model embodiment provides a powder solid packaging machine, such as Figure 1 As shown, the device includes a storage bin 1, with a conveying pipe 2 at the bottom of the storage bin 1 that communicates with the interior of the storage bin 1. An annular airbag 3 is fitted onto the conveying pipe 2. When the opening of the packaging bag is placed over the conveying pipe 2 for packaging, the annular airbag 3 is inflated. After inflation, the annular airbag 3 can open and seal the opening of the packaging bag, which can prevent powdered chemical reagents from falling into the packaging bag and overflowing from the opening of the packaging bag during the packaging process. This can prevent powdered chemical reagents from polluting the air and harming human health.

[0021] In this embodiment, a feeding hopper 11 is installed on the top of the storage bin 1. Powdered chemical reagents can be added into the storage bin through the feeding hopper 11. At the same time, the bottom of the storage bin 1 is funnel-shaped, which can prevent powdered chemical reagents from remaining at the bottom of the storage bin 1.

[0022] In this embodiment, as Figure 2 As shown, the baling machine also includes a feeding mechanism 4, which includes a feeding rod 41 and a drive device 42 for driving the feeding rod 41 to rotate. The drive device 42 is one of an electric motor, a hydraulic motor, or a pneumatic motor. The lower end of the feeding rod 41 is located inside the conveying pipe 2 and has auger blades 43 on its outer wall to control the output of powdered chemical reagents through the conveying pipe 2, which can also play a role in accurate measurement. The upper end of the feeding rod 41 is located inside the storage bin 1 and has stirring blades 44 on its outer wall. The stirring blades 44 can stir the powdered chemical reagents inside the storage bin 1 to prevent the powdered chemical reagents from clumping and affecting the baling work.

[0023] In this embodiment, as Figure 3 As shown, the annular airbag 3 includes an airbag body 31, an inflation valve 33, an exhaust valve 34, and a support sleeve 32 located at the central hole of the airbag body 31. The support sleeve 32 can be fitted onto the conveying pipe 2 during the installation of the annular airbag 3, as shown. Figure 4 As shown, the support sleeve 32 includes a sleeve body 321. The outer wall of the sleeve body 321 is connected to the inner wall of the airbag body 31. Both ends of the sleeve body 321 are provided with retaining rings 322. The two sides of the two retaining rings 322 are respectively connected to the two sides of the annular airbag 3. The annular airbag 3 with the above design has high structural strength and small shape change after inflation and deflation, so it can better seal the bag opening of the packaging bag.

[0024] It should be noted that the airbag body 31 is connected to the inflation valve 33 and the deflation valve 34. The inflation valve 33 is connected to the inflation pump. At the same time, both the inflation valve 33 and the deflation valve 34 are solenoid valves, which can automatically control the inflation or deflation of the airbag body 31, and have a high degree of intelligence.

[0025] In this embodiment, two nuts 21 are threadedly connected to the feed pipe 2 to fix the support sleeve 32 to the feed pipe 2, which facilitates the disassembly and assembly of the support sleeve 32, thereby facilitating the disassembly and assembly of the annular airbag 3.

[0026] Specific principle: During packaging, the opening of the packaging bag is placed on the conveying pipe 2. After the opening of the packaging bag is placed on the conveying pipe 2, air is inflated into the annular airbag 3 to open and seal the opening of the packaging bag. After the opening of the packaging bag is opened and sealed, the driving device 42 drives the feeding rod 41 to rotate. The feeding rod 41 drives the auger blade 43 to rotate, so that the powdered chemical reagent inside the storage bin 1 is output through the conveying pipe 2 and enters the packaging bag for packaging. After packaging is completed, the driving device 42 stops working and at the same time, the gas inside the annular airbag 3 is discharged to loosen the opening of the packaging bag.
