Description

Technical Field

[0001] The utility model relates to the technical field of millet processing, in particular to a millet packaging device. Background Art

[0002] Corn is made from the shell of the cereal crop "millet". Because of its small grain size, it is named millet. Corn enters the spleen, stomach, and kidney meridians, has the effect of strengthening the spleen and stomach, and is especially suitable for people with weak spleen and stomach. The last step after millet processing is packaging. Generally, millet is put into packaging bags for sale, so packaging equipment is needed.

[0003] For example, the patent document with the announcement number CN213384808U discloses a millet packaging device. The millet packaging device, through the coordinated use of a motor, a main shaft, a spiral feeding blade, a control box, a handle, a drive switch and a quantitative adjustment switch, enables the device to limit the amount of each packaging in advance through the quantitative adjustment switch when packaging millet, so that the quality of each bag of millet packaged can be the same to a certain extent. At the same time, the device sets the drive switch on the handle, so that the device staff can ensure that the rice bag is completely located under the discharge pipe when packaging. After the millet is put into the bag, it usually needs to be transported to the sealing process, so that the millet bag needs to be able to stand on the conveyor belt.

[0030] Working principle: When in use, put the packaging bag on the two support plates 302, and then the cylinder 306 drives the two upper racks 301 to move away from each other, so that the support plate 302 opens the packaging bag, and the upper rack 301 drives the gear 304 to rotate, and the gear 304 drives the lower rack 301 to move toward the middle, so that the support plate 302 and the clamping plate 303 clamp the packaging bag, and at the same time, the upper rack 301 drives the top block 308 to move, and under the elastic force of the compression spring 203, the lifting plate 202 drives the conduit 201 to move downward, so that the conduit 201 is inserted into the packaging bag, and then the hopper 102 starts to load millet into the packaging bag. After loading, when the driving motor 501 drives the rotating shaft 502 and the cam 503 to rotate, the cam 503 intermittently moves the top plate 504 is pushed up, and the reset spring 505 is stretched. Then, under the action of the reset spring 505, the top plate 504 is reset downward, and this reciprocating movement causes the top plate 504 to intermittently hit the bottom of the millet bag, causing the millet to settle downward, lowering the center of gravity of the millet bag, and flattening the bottom of the millet bag. Then the cylinder 306 pushes the upper rack 301 close to the guide tube 201 for reset. The support plate 302 and the splint 303 release the millet bag. At this time, the millet bag is located on the storage table 4, and then the translation motor 603 drives the bidirectional screw rod 604 to rotate, and the bidirectional screw rod 604 drives the two stabilizing plates 605 to approach each other, thereby slightly clamping the millet bag, and the electric telescopic cylinder 601 pushes the guide rail 602 forward to push the millet bag onto the conveyor belt mechanism 7.
