[0044] A method for an automated powder delivery system, comprising the following steps:

[0045] 1) The forklift operator delivers the whole stack of powdered sugar to the pallet conveyor 1. The buffer capacity of each variety is two to three stacks. After the pallet conveyor 1 moves the whole stack of powdered sugar to the working range of the robot depalletizer 3, the robot depalletizer 3 moves the bagged powdered sugar to the material conveyor 4 through the suction cup;

[0046] 2) The material conveyor 4 conveys the bagged powdered sugar, and uses a rectangular tube to replace the traditional round tube roller to form a bumpy conveyor, and the crystal crusher 5 is started to knock the bagged powdered sugar to break the agglomerated powdered sugar, and then transport it to the lifting dust collector 6;

[0047] 3) When the lifting dust collector 6 drives the bagged powdered sugar to move upward, the dust on the outer surface of the bagged powdered sugar can be adsorbed and cleaned, and the cleaned bagged powdered sugar is transferred to the interior of the automatic bag cutting machine 7;

[0048] 4) After the automatic bag cutting machine 7 cuts the bagged powdered sugar, the powdered sugar falls into the screening machine 9 under the action of gravity, and the waste bags after cutting are stored in the waste bag storage box 8 for subsequent processing by staff. Specifically, the automatic bag cutting machine 7 fixes the outer packaging of the bagged powdered sugar with a clamp, and then cuts the bagged powdered sugar with a cutter, so that the powdered sugar falls into the screening machine 9 under the action of gravity. Since the clamp clamps the outer packaging of the powdered sugar, the outer packaging will not fall, and finally the waste bags are placed in the waste bag storage box 8 by the automatic bag cutting machine 7;

[0049] 5) After the sieving machine 9 filters the impurities in the powdered sugar, the vacuum feeder 12 is started to move the powdered sugar into the buffer tank 13 by means of negative pressure, thereby completing the transportation of the powdered sugar.

[0050] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0051] The working principle of the above embodiment is:

[0052] (1) The whole stack of powdered sugar is delivered to the pallet conveyor 1 by a forklift, and the buffer capacity of each variety is two to three stacks. The robot depalletizer 3 can automatically identify the variety and automatically depalletize, and transport it to the material conveyor 4. By starting the electric push rod 502, the pressing plate 503 moves up and down to crush the raw material bag, and then moves to the inside of the lifting dust collector 6 for dust removal, and then sends it to the automatic bag cutting machine 7 for bag opening. The material falls into the inside of the screening machine 9 to filter out foreign matter. Then, the vacuum loader 12 is used to generate negative pressure inside the screening machine 9, so that the raw material enters the buffer tank 13 through the connecting pipe 11 for subsequent use, and the empty stacks are automatically stacked by the empty plate stacker 2, and then centrally emptied and processed by a forklift.

[0053] (2) When the raw material bag moves to the outer surface of the lifting conveyor belt 602, it will be driven by the lifting conveyor belt 602 to move to the inside of the protective box 601. At this time, starting the fan 611 can generate a certain negative pressure inside the protective box 601 to pull the dust. When the raw material bag passes through the cleaning component 15, it will squeeze the inclined surface on the left side of the cleaning brush 1504, so that the cleaning brush 1504 pushes the cleaning plate 1503 to move toward the inside of the cleaning block 1501 and squeezes the cleaning spring 1502, so that the cleaning brush 1504 can maintain effective fit with the raw material bag with an arc-shaped edge, so that the raw material can be cleaned. The dust on the outer surface of the bag is cleaned, and when the raw material bag moves, it will also come into contact with the cleaning brush 603. The dust entering the air will enter the interior of the negative pressure pipe 604 due to the negative pressure and enter the interior of the dust box 606 through the connecting pipe 605, and will be blocked by the filter assembly, so that the dust is collected in the dust box 606 for subsequent cleaning. When it is necessary to clean the filter layer 608, it is only necessary to rotate the fixing bolt 610 to make the fixing bolt 610 and the dust box 606 lose the threaded fixation, and then pull the positioning frame 609 upwards to take out the filter layer 608, so that the filter layer 608 can be easily replaced and cleaned.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0055] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.

The automatic powder conveying system according to claim 1, characterized in that: The filter assembly comprises a filter layer (608), a positioning frame (609) and a fixing bolt (610); the filter layer (608) is slidably connected to the dust box (606); the top of the dust box (606) is fixed to the positioning frame (609); the interior of the positioning frame (609) is slidably connected to the fixing bolt (610) threadedly connected to the dust box (606).

10. A method of using the automatic powder delivery system described in any one of claims 1 to 9 above, characterized in that: The following steps are involved: 1) A forklift operator delivers a whole stack of powdered sugar to a pallet conveyor (1). The buffer capacity of each variety is two to three stacks. After the pallet conveyor (1) moves the whole stack of powdered sugar to the working range of a robot depalletizer (3), the robot depalletizer (3) moves the bagged powdered sugar to a material conveyor (4) through a suction cup. 2) The material conveyor (4) conveys the bagged powdered sugar by using a rectangular tube to replace the traditional round tube roller to form a bumpy conveying, and the crystal crusher (5) is started to knock the bagged powdered sugar to break the agglomerated powdered sugar and then transport it to the lifting dust removal machine (6); 3) When the lifting dust collector (6) drives the bagged powdered sugar to move upward, the dust on the outer surface of the bagged powdered sugar can be adsorbed and cleaned, and the cleaned bagged powdered sugar is transferred to the interior of the automatic bag cutting machine (7); 4) After the automatic bag cutting machine (7) cuts the bagged powdered sugar, the powdered sugar falls into the inside of the screening machine (9) under the action of gravity, and the cut waste bags are stored in the inside of the waste bag storage box (8) and are subsequently processed by the staff; 5) After the sieving machine (9) filters the impurities in the powdered sugar, the vacuum feeder (12) is started to move the powdered sugar into the buffer tank (13) by means of negative pressure, thereby completing the transportation of the powdered sugar.
