In the drawings:
FIG. 1 is a side view of the present invention;
labeled as: 1. powder bags; 2. a negative pressure dust suction device; 3. a high-pressure air knife; 4. an electrostatic elimination ion wind rod; 5. a vacuum chuck; 6. a storage cylinder; 7. a bag cutting blade; 8. a material suction pipe.
Detailed Description
Example 1
As shown in fig. 1, the powder bag 1 is laid horizontally vertically on a conveyor from the inlet of the powder conveyor, and the conveyor feeds the powder bag into a pipeline. Dust on the powder bag 1 is blown off by the upper and lower air knives at the high-pressure air knife 3, and the dust is blocked and collected by the negative pressure dust suction device 2 at the front part. After dust removal, the powder bag 1 is static-free by the static-free ion wind rods 4 arranged on the two sides, and then moves to the storage device. After the powder bag 1 reaches the storage device, the powder bag turns downwards until the powder bag is stopped by the upper cover of the storage cylinder 6, the photoelectric sensor arranged in the storage device senses the signal and sends the signal to the control device, after the signal is received, the transmission controller stops the conveyor belt, the vacuum chuck 5 extends out, the powder bag 1 is sucked, the bag cutting blade 7 cuts the bottom of the powder bag 1, and the vacuum feeding machine starts to pump the powder.
Example 2
As shown in figure 1, the powder conveying belt is arranged in a rectangular pipeline, and a negative pressure dust suction device 2 is arranged at the inlet of the pipeline, so that dust blown off from a powder bag 1 can be collected and prevented from being diffused to the space. The upper side and the lower side of the powder conveying belt are respectively provided with a high-pressure air knife 3 for blowing off dust on the powder bag. And the static electricity eliminating ion wind rods 4 are respectively arranged at the two sides of the conveying belt behind the high-pressure wind knife 3 and are used for eliminating static electricity carried on the powder bag 1 to prevent fine dust in the static electricity adsorption air from entering the powder.
The tail end of the conveying belt is connected with a material storage device. As shown in the attached drawing, the tail end of the powder conveying belt rotates downwards 45-70 degrees, so that the bottom of the powder bag 1 is contacted with the upper cover of the powder storage barrel 6. A group of small vacuum chucks 5 on the back of the conveyor belt suck the powder bags, the powder bags 1 are fixed on the conveyor belt, and after all the powder in the powder bags 1 flow to the storage barrel 6, the vacuum chucks 5 pull out the empty powder bags 1.
The upper cover of the storage barrel 6 is provided with a rectangular feed inlet, and the width of the feed inlet is larger than that of the powder bag 1. The lower part of the feed inlet is provided with a bag cutting blade 7 which can slide left and right and is used for cutting the bottom of the powder bag 1 so as to lead the powder to flow into the storage barrel 6. In addition, in the blanking process, the upper part of the powder bag 1 is fixed by the vacuum chuck 5 so as to smoothly blank, and the powder bag 1 is always covered on the feeding hole, so that dust can be prevented from being mixed. The upper cover of the material storage cylinder 6 is inserted into the material suction pipe 8 of the vacuum feeding machine, and the material suction and powder feeding of the vacuum feeding machine work synchronously, so that the negative pressure generated during material suction is beneficial to accelerating blanking
