Detailed Description

The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.

The bowl dropping separator comprises three bowl dropping mechanisms which are uniformly distributed on the circumference, each bowl dropping mechanism comprises a rotating shaft 1 and a bowl dropping wheel 2, the rotating shaft 1 is vertically arranged, the lower part of the rotating shaft 1 is arranged in a bearing seat 5 in place through a bearing assembly, the bearing seat 5 is arranged at the bottom of a machine bedplate 6, the bowl dropping wheels 2 (in a cylindrical shape, the length direction is upward and downward) are fixedly arranged at the tops of the rotating shafts 1, a spiral guide groove 2-1 is formed in an outer circumferential wheel body of the bowl dropping wheel 2, the notch at the upper end of the spiral guide groove 2-1 is positioned at the edge of the top of the bowl dropping wheel 2, and the notch at the lower end of the spiral guide groove 2-1 is positioned at the edge of the bottom of the bowl dropping wheel 2, as shown in figures 1 and 2.

The three rotating shafts 1 are connected through a synchronous belt wheel transmission pair 4, the synchronous belt wheel transmission pair 4 comprises a synchronous belt and three synchronous belt wheels, each synchronous belt wheel is fixedly arranged at the bottom of the corresponding rotating shaft 1, the synchronous belt is connected with the three synchronous belt wheels, one synchronous belt wheel is set as a driving wheel, the synchronous belt wheel is connected with a motor through a speed reducer, under the driving of the speed reducer driven by the motor, the synchronous belt drives the three synchronous belt wheels, namely the three rotating shafts 1 synchronously rotate in the same direction, the three rotating shafts 1 synchronously drive the three bowl-falling wheels 2 to rotate in the same direction, and the rotating direction of each rotating shaft 1 is consistent with the downward rotation (or called as downward rotation) direction of the spiral guide groove 2-1 of the bowl-falling wheel 2, as shown in fig. 1 and fig. 2.

Bowl inlets of the powder bowls 3 (with big top and small bottom) are formed among the upper end notches of the three spiral guide grooves 2-1 of the three bowl falling wheels 2, bowl outlets of the powder bowls 3 (with big top and small bottom) are formed among the lower end notches of the three spiral guide grooves 2-1, and the diameters of circumferences of the bottoms of the three spiral guide grooves 2-1 are matched with the diameters of the bowl outlets of the powder bowls 3 (with big top and small bottom), as shown in fig. 1 and 2.

The automatic bowl dropping and feeding machine comprises a bowl dropping separator and a conveyor belt 7, wherein the conveyor belt 7 is arranged below a bowl outlet between three bowl dropping wheels 2, the sorted powder bowls 3 are sequentially conveyed to a next working procedure by the running conveyor belt 7, and the powder bowls 3 for dropping and sorting of the bowl dropping separator are stacked at a bowl inlet between the three bowl dropping wheels 2, as shown in figure 3.

The invention relates to an operation scheme of a bowl falling separator, which comprises the following steps:

1. dozens of stacked powder bowls 3 are placed at the bowl inlet among the three bowl dropping wheels 2, the edge of the bowl opening of the powder bowl 3 at the lowest layer is placed on the upper end notches of the three spiral guide grooves 2-1, and the upper end notches of the three spiral guide grooves 2-1 form stable support for the stacked powder bowls 3.

2. When the motor is started, the three rotating shafts 1 synchronously drive the three bowl dropping wheels 2 to synchronously rotate in the same direction, and due to the downward rotation (downward movement) guide of the spiral guide grooves 2-1, the bowl opening edge of each powder bowl 3 sequentially enters the three spiral guide grooves 2-1 from the notch at the upper end and is conveyed downwards along the three spiral guide grooves 2-1.

3. Each powder bowl 3 conveyed downwards to the notches at the lower ends of the three spiral guide grooves 2-1 falls from a bowl outlet between the three bowl falling wheels 2 in sequence.

4. And the three bowl dropping wheels 2 continuously run to drop and sort all the powder bowls 3, and the motor is turned off.

5. And placing another stacked powder bowl 3 at a bowl inlet between the three bowl dropping wheels 2, and repeating the steps 1-4 to continuously drop and sort the stacked powder bowls 3.

The operation mode of the automatic bowl dropping and feeding machine is that on the basis of the operation of the bowl dropping separator, the powder bowls 3 dropped on the bowl outlet by the bowl dropping separator are sequentially received and conveyed to the next process through the conveyor belt 7, so that the automatic flow of dropping and separating and bowl discharging and conveying is completed.
