An air inlet 203 is provided at the bottom of the concave surface 2012. The air inlet 203 of the present invention is composed of a plurality of air inlet holes, which are arranged in a circular array to uniformly blow the material. The specific number of air inlet holes 203 can be set according to actual needs and is not particularly limited here.

[0035] Preferably, a notch is provided on the outer peripheral surface of the connecting edge 2011 to facilitate connection to the feed channel 300 described below.

[0036] The air inlet 203 is connected to the lower air gourd blowing device 400. The lower air gourd blowing device 400 includes a sealing cover 401, a lower air blowing joint 402 and a sealing member 403.

[0037] The inner wall of the sealing cover 401 is provided with concentric inner and outer grooves, and the inner groove is provided with a through hole. The sealing cover 401 is fixed to the outer side of the lower concave surface 2012, and the air inlet 203 is placed in the inner groove. A circular sealing member 403 is provided in the outer groove to further ensure the sealing of the lower concave surface 2012. One end of the lower blowing joint 402 passes through the through hole of the sealing cover 401 and communicates with the air inlet 203, and the other end is connected to the air supply unit (not shown). When the air supply unit is started, the lower blowing joint 402 blows air from the bottom to the top into the warehouse body 201, and the sealing ring 000 can be blown into the feeding channel 300.

[0038] In order to further improve the efficiency of blowing the sealing ring 000 into the feeding channel 300, an upper air hoist blowing device 500 is also connected to the warehouse body 201.

[0039] The upper air gourd blowing device 500 includes an air inlet plate 501 and an air inlet plate cover 505. Both the air inlet plate 501 and the air inlet plate cover 505 are concentric circular plates, and their diameters match the diameter of the lower concave surface 2012 of the bin body 201.

When the air supply unit is activated, the upper air blowing connector 503 blows air from top to bottom through the air flow guide 506 toward the chamber body 201. The lower air hoist blowing device 400 blows air from bottom to top toward the sealing ring 000. The combined airflow direction of the two blows the sealing ring 000 into the feeding channel 300.

[0043] Preferably, an ion generator 700 is provided on the base 100 and connected to the first mounting plate. The outlet of the ion generator 700 is connected to the air supply unit, so that the blowing airflow of the lower and upper air hoist blowing devices 400 and 500 is an electrostatic airflow, thereby eliminating the static electricity of the sealing ring itself, thereby avoiding the problem of material jamming caused by electrostatic adsorption.

[0044] Preferably, a photoelectric sensor 900 is provided on the bin cover 202 , which is located on the top surface of the first mounting plate and is used to detect whether there is gas leakage in the bin body 201 .

To facilitate assembly with other components, the discharge guide plate 301 and the guide plate cover plate 302 have an arcuate edge on the side facing the air inlet disk 501, and the arcuate edge and the notch portion 504 of the air inlet disk 501 can be combined to form a circle. The bottom surface of the discharge guide plate 301 also has a stepped surface, which is fixedly connected to the notch of the connecting edge 2011 and is snapped into the notch portion 504. The guide plate cover plate 302 covers the upper surface of the discharge guide plate 301. At this time, the upper surface of the guide plate cover plate 302 and the upper surface of the air inlet disk 501 are located in the same plane, and the air inlet disk cover plate 505 covers the air inlet disk 501 and the guide plate cover plate 302.

[0046] The surface of the discharge guide plate 301 is provided with a groove guide rail 303, and the sealing ring 000 is blown into the groove guide rail 303 by the lower air hoist blowing device 400 and the upper air hoist blowing device 500 and discharged. The number of groove guide rails 303 can be set according to actual production needs to accurately meet the discharge quantity. In the utility model, two basically parallel groove guide rails 303 are provided, and each groove guide rail 303 is basically arranged linearly. In order to facilitate the sealing ring 000 to enter the groove guide rail 303, the cross-sectional area of the feed port 3033 of each groove guide rail 303 is larger than the diameter of the sealing ring 000, and the feed port 3033 is arranged in a slightly arc shape to facilitate the introduction of the sealing ring; the size of the other groove parts of the groove guide rail 303 is comparable to the diameter of the sealing ring 000. Each feed port 3033 is located between the lower concave surface 2012 and the airflow guide groove 506, and is flush with the outer edge of the lower concave surface 2012.

[0047] Preferably, a stop portion 3031 is provided at the discharge port end of each groove guide rail 303. After the sealing ring 000 is blown into the groove guide rail 303, it stops at the stop portion 3031. Each stop portion 3031 has an arc surface on the side away from the bin body that is adapted to the outer surface of the sealing ring 000 to accommodate the sealing ring. In addition, each stop portion 3031 has a central hole to facilitate the subsequent removal of the sealing ring 000.

[0048] Furthermore, an optical fiber sensor 800 is provided on the discharge guide plate 301 to detect whether the sealing ring 000 has been discharged in place. To accommodate the sensing unit of the optical fiber sensor 800, an optical fiber mounting groove 3032 is provided on the discharge guide plate 301 near the end of the stop portion 3031, and the optical fiber mounting groove 3032 communicates with the stop portion 3031.

[0049] When the guide plate cover 302 covers the upper surface of the discharge guide plate 301 , each stop portion 3031 and the optical fiber installation groove 3032 are located outside the guide plate cover 302 .

[0050] Preferably, a plurality of guide rail air inlet holes 304 are provided on each groove guide rail 303 and within the coverage area of the guide plate cover 302. Each guide rail air inlet hole 304 is connected to a guide rail air blowing connector 305, and the guide rail air blowing connector 305 is connected to the air supply unit. When the sealing ring 000 is blown into the groove guide rail 303 along with the electrostatic air flow, the air supply unit is started, and the guide rail air blowing connector 305 blows the electrostatic air flow into the groove guide rail 303 through the guide rail air inlet hole 304, further avoiding the problem of material blockage. The number of guide rail air inlet holes 304 can be set according to the length of the groove guide rail 303 or the amount of air flow, without special restrictions. In the present utility model, three guide rail air inlet holes 304 are provided on each groove guide rail 303 at intervals.

[0051] In addition, to prevent the sealing ring 000 from being blown off, a stop device is provided at the outlet end of the groove guide rail 303.
