[0019] The technical scheme of the utility model will be further described in detail below in combination with the drawings and examples.

[0020] For example, Figures 1-3 ​As shown, a screening and feeding device of a modified atmosphere window base comprises a rack 6, a stock bin 5, a conveyor I 8, a hopper 7, a conveyor II 3 and a flow guide plate 9; the conveyor I 8 is installed on the rack 6, and the conveyor I 8 is arranged in an inclined manner, the lower end of the conveyor I 8 is located in the stock bin, the upper end of the conveyor I 8 is provided with the hopper 7 for receiving materials, one end of the conveyor II 3 is located below the discharge port of the hopper 7, and the conveyor II 3 is located on one side of the stock bin 5, one side of the conveyor II 3 is provided with the flow guide plate 9, and the other side of the conveyor II 3 is provided with a blowing assembly 2 corresponding to the flow guide plate 9, the blowing assembly 2 comprises a nozzle and a gas pipe connected with the nozzle, the nozzle is installed on the support frame of the conveyor II 3, and the gas pipe is connected with a gas pump.

[0021] In the utility model, the conveyor I 8 and the conveyor II 3 are both composed of a support frame, a driving roller, a driven roller and a conveying belt, the driving roller is driven by a motor connected with a speed reducer, and in order to facilitate feeding, the conveying belt of the conveyor I 8 is provided with a material lifting plate.

[0022] The flow guide plate 9 is located above the conveyor II 3, the flow guide plate 9 is located directly above the conveying belt of the conveyor II 3, and the flow guide plate 9 is fixedly connected to the side surface of the support frame of the conveyor II 3, the distance between the flow guide plate 9 and the surface of the conveying belt of the conveyor II 3 is less than the thickness of the modified atmosphere window base 1, one side surface of the flow guide plate 9 corresponding to the blowing assembly 2 is an inclined surface, the one side surface of the flow guide plate 9 gradually inclines from one side to the other side of the conveyor II 3 along the material conveying direction, the one side surface of the flow guide plate 9 and the other side edge of the conveyor II 3 form a material conveying channel, the inclined arrangement of the one side surface of the flow guide plate 9 makes the material conveying channel gradually narrow along the conveying direction, the minimum distance formed between the one side surface of the flow guide plate 9 and the other side edge of the conveyor II 3 is greater than the radius of the modified atmosphere window base 1 and less than the diameter of the modified atmosphere window base 1, which facilitates the conveying of the base 1 on one hand and facilitates the blowing assembly 2 to blow the concave upward base 1 into the stock bin 5 on the other hand.

[0023] The nozzle of the blowing assembly 2 is arranged close to the other side edge of the conveyor II 3, and the nozzle cannot be higher than the surface of the conveyor II, so as to avoid affecting the conveying of the base.

[0025] In order to facilitate the material in the hopper 7 from the discharge port fall into the conveyor two 3, the bottom of the hopper 7 is inclined downward.

[0026] In the specific work, the base is conveyed from the bin by the conveyor one to the hopper, and then slides from the hopper to the conveyor two, and the base is conveyed through the anti-stacking plate and the guide plate to the material conveying channel between the guide plate and the blowing assembly, when passing above the blowing assembly 2, if the step at one end of the base faces downward, the base will be blown by the blowing assembly 2 and fall into the bin, because the blowing assembly 2 blows corresponding to the step surface, the step surface is blown and falls into the bin, if the flat structure at the other end of the base faces downward, the blowing force on the base is very small, and the conveying is not affected.

[0027] It should be noted that in the utility model, the conveyor one 8 and the conveyor two 3 are both known products in the prior art, and the structure and working principle thereof are well known to those skilled in the art.
