For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0022] The utility model will be further described below in combination with the drawings:

[0023] Example 1: As Figures 1-4 As shown, a novel automatic flip-plate unloading device includes a material container 10 and an unloading device 13. The unloading device 13 is located at the output end of the material container 10 and includes a mounting frame 15 and an mounting pipe 14. The mounting frame 15 is connected to the material container 10 and has a sealing airbag 8 inside. One end of the mounting pipe 14 is connected to the mounting frame 15, and a distribution plate lower flange 6 is provided inside the mounting pipe 14. The distribution plate lower flange 6 is rotatably connected to the mounting pipe 14. An airflow distribution plate 5 is provided on the distribution plate lower flange 6, and an upper distribution plate flange 7 is provided on the airflow distribution plate 5. When the sealing airbag 8 is inflated, it will contact the upper distribution plate flange 7. A pneumatic actuator 1 is provided on the outer wall of the mounting pipe 14, and the output end of the pneumatic actuator 1 is connected to the lower distribution plate flange 6. When the pneumatic actuator 1 outputs, the lower distribution plate flange 6 will drive the upper distribution plate flange 7 and the airflow distribution plate 5 to rotate about the cross-sectional diameter of the mounting pipe 14.

[0024] like Figure 3 and Figure 4 As shown, an installation sleeve 2 and a support pipe 9 are installed through the installation pipe 14, and the installation sleeve 2 and the support pipe 9 are coaxial, with their axes passing through the center of the cross-section of the installation pipe 14. The pneumatic actuator 1 is fixedly installed at one end of the installation sleeve 2. A drive shaft 3 is rotatably installed inside the installation sleeve 2. One end of the drive shaft 3 is connected to the output end of the pneumatic actuator 1, and the other end of the drive shaft 3 is connected to the lower flange 6 of the distribution plate. A rotating shaft 12 is rotatably installed inside the support pipe 9, and one end of the rotating shaft 12 is connected to the lower flange 6 of the distribution plate.

[0025] Specifically, a pointer 11 is fixedly installed at the other end of the rotating shaft 12 to facilitate quick determination of the state of the airflow distribution plate 5.

[0026] Specifically, bearings 4 are also installed inside the mounting sleeve 2 and the support tube 9. The drive shaft 3 is rotatably mounted inside the mounting sleeve 2 through the bearings 4, and the rotating shaft 12 is rotatably mounted inside the support tube 9 through the bearings 4. This can reduce friction and extend the service life of the equipment. At the same time, the bearings 4 used are self-lubricating bearings, which can further extend the service life of the equipment and reduce the failure rate.

[0027] Specifically, both the upper flange 7 and the lower flange 6 of the distribution plate are circular structures, which can not only fix the airflow distribution plate 5, but also reduce the mass and reduce the burden on the pneumatic actuator 1. Furthermore, the longitudinal section of the upper flange 7 of the distribution plate is an inverted "V" shape. In this way, after the airbag is inflated and fits against the flange 7 of the distribution plate, the weight of some of the material can be used to make the slope of the airbag and the flange 7 of the distribution plate fit more tightly, thereby improving the sealing effect.

[0028] The working process of the embodiment: before use, the discharging device 13 is in a closed state, at this time the sealing air bag 8 is in an inflated state, after the sealing air bag 8 is inflated, the sealing air bag 8 is expanded out of the mounting frame 15 and is attached to the flange 7 on the distribution plate, thereby sealing the discharging port of the material container 10, at this time the material is accumulated in the material container 10.

[0029] When discharging is needed, the gas in the sealing air bag 8 is first released, so that the sealing air bag 8 is retracted into the mounting frame 15, then the pneumatic actuator 1 starts to rotate in a forward direction, the flange 6 under the distribution plate is driven by the transmission shaft 3 to rotate around the axis of the transmission shaft 3 and the axis of the rotating shaft 12, after the airflow distribution plate 5 is rotated by the transmission shaft 3, the material in the material container 10 passes through the mounting pipe 14, thereby achieving discharging.

[0030] When discharging is needed, the gas in the sealing air bag 8 is first released, so that the sealing air bag 8 is retracted into the mounting frame 15, then the pneumatic actuator 1 starts to rotate in a forward direction, the flange 6 under the distribution plate is driven by the transmission shaft 3 to rotate around the axis of the transmission shaft 3 and the axis of the rotating shaft 12, after the airflow distribution plate 5 is rotated by the transmission shaft 3, the material in the material container 10 passes through the mounting pipe 14, thereby achieving discharging.

[0031] It should be noted that the maximum angle of rotation of the pneumatic actuator 1 to drive the airflow distribution plate 5 is ninety degrees as shown in Figure 2 , in this state, the opening degree is the largest.

[0032] The above describes one embodiment of the utility model in detail, but the content is only the preferred embodiment of the utility model, and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement within the scope of the utility model application should still belong to the patent coverage range of the utility model.
