It is suitable for large-scale production but not suitable for smaller-scale packaging. Packaging equipment with a low degree of automation is complicated to operate. Workers need to send pre-bagged corn to the vacuum equipment for sealing. However, this type of packaging equipment needs to pause for a certain period of time during the corn vacuum sealing process, which will cause the entire packaging process to pause for the same length of time, making continuous feeding impossible and reducing packaging efficiency.

[0033] Example: Reference Figure 1-6 A fresh corn packaging machine shown in the figure comprises a base 1 and a guide plate 2, the upper surface of the base 1 is rotatably connected with a rotating column 3, the peripheral side surface of the rotating column 3 is fixedly sleeved with a mounting platform 4, the peripheral side surface of the mounting platform 4 is annularly rotatably connected with a plurality of placement frames 5, a top plate 6 is fixed to the top of the rotating column 3, a top cover 7 is fixed at the position of the lower surface of the top plate 6 corresponding to the placement frame 5, a first electric push rod 10 is fixedly installed at the position of the upper surface of the top plate 6 corresponding to the top cover 7, the output end of the first electric push rod 10 slides through the top plate 6 and is fixedly connected to the upper surface of the top cover 7, and the feed end of the guide plate 2 is located directly below a placement frame 5;

[0034] A vacuum pump 11 is fixedly installed on the upper surface of the top cover 7, and the input end of the vacuum pump 11 is fixedly connected to the inner cavity of the top cover 7. A lower horizontal plate 19 is fixed to the inner bottom surface of the placement frame 5, and an upper horizontal plate 18 is fixed to the inner side of the placement frame 5 and directly above the lower horizontal plate 19. A lifting plate 20 is slidably matched between the upper horizontal plate 18 and the lower horizontal plate 19. A rubber strip 23 and two electric heating plates 24 are fixed on the upper surfaces of the lifting plate 20 and the lower horizontal plate 19. The rubber strip 23 is located between the two electric heating plates 24. A first servo motor 8 is fixed to the lower surface of the base 1 through a bracket, and the output end of the first servo motor 8 is fixedly connected to the bottom end of the rotating column 3 through a coupling. Four supporting legs 25 are fixed to the lower surface of the base 1, and the feeding end of the guide plate 2 is tilted upward.

[0035] In the process of packaging corns, the staff first places the corns in the positioning groove 17, adjusts the position of the packaging bag so that the corns are roughly located in the middle of the packaging bag, then pinches both sides of the bag opening of the packaging bag with both hands and pulls it outward to close the bag opening of the packaging bag, and sends the closed bag opening to between the lifting plate 20 and the lower horizontal plate 19. At this time, the lifting plate 20 moves downward, and the rubber strips 23 on the lifting plate 20 and the lower horizontal plate 19 approach each other and initially squeeze the bag opening, and at this time, the lifting plate 20 and the electric heating plate 2 on the lower horizontal plate 19 4 will not squeeze the bag opening, and air can still flow out through the gap of the bag opening. The first electric push rod 10 is set to control the lifting and lowering of the top cover 7. After the top cover 7 moves down, the top of the placement frame 5 will be closed, so that the top cover 7 and the placement frame 5 form a closed vacuum environment, and the first servo motor 8 is set to drive the rotating column 3 to rotate intermittently at a specific angle to achieve continuous feeding of corn. During the rotation of the placement frame 5, the vacuum pump 11 is started to extract the air inside the placement frame 5, so that the air inside the placement frame 5 is thin to form a negative pressure environment, and the air in the packaging bag The liquid flows out from the bag opening. When the negative pressure in the placing frame 5 reaches a specific value, the vacuum pump 11 is turned off, and the lifting plate 20 moves down a specific distance again. The rubber strip 23 on the lifting plate 20 and the lower horizontal plate 19 approaches each other and tightly squeezes the bag opening. In this process, the rubber strip 23 will be deformed, and the two electric heating plates 24 on the lifting plate 20 and the lower horizontal plate 19 approach each other and tightly clamp the bag opening. The two electric heating plates 24 will heat up after being powered on, which will cause two hot air lines to appear at the bag opening of the packaging bag, thereby realizing double heat sealing treatment of the bag opening of the packaging bag, so that the sealing effect of the packaging bag is better. When the placement frame 5 rotates to the top of the guide plate 2, the vacuuming and heat sealing operations are completed. When the placement frame 5 rotates to the top of the guide plate 2, the electromagnetic valve on the placement frame 5 opens, and the outside air enters the placement frame 5 through the electromagnetic valve, so that the air pressure inside and outside the placement frame 5 reaches a balance, and the first electric push rod 10 drives the top cover 7 to rise, and the placement frame 5 rotates downward to 90°. At the same time, the lifting plate 20 moves up, and the corn will automatically fall into the guide plate 2 under its own gravity. The upward tilt of one end of the guide plate 2 is convenient for the packaged corn to be discharged.

[0036] In order to facilitate the staff to better place the corn in the placement frame 5, so that the packaged corn can be discharged quickly and stably, in this embodiment, a positioning groove 17 is provided on the bottom surface of the placement frame 5, a sealing gasket 13 is fixed on the lower surface of the top cover 7, a feed inlet is provided on one side of the placement frame 5, a vertical plate 12 for closing the feed inlet is fixed on the lower surface of the top cover 7, and a similar sealing gasket 13 is fixed on the lower surface of the vertical plate 12. The provision of the feed inlet and the vertical plate 12 facilitates the entry and exit of corn, and the provision of the sealing gasket 13 can make the top cover 7 and the placement frame 5 more tightly closed.

[0037] In order to enable the top cover 7 to slide vertically stably, in this embodiment, a group of sliding rods 9 are fixed to the upper surface of the top cover 7 , and the top ends of the sliding rods 9 slide through the top plate 6 .

[0038] In order to enable the placement frame 5 to rotate stably and the corn to be discharged stably, in this embodiment, a plurality of hinge seats 14 are fixed in a ring shape on the side of the mounting platform 4, a hinge block 16 is fixed at one end of the placement frame 5, and the hinge block 16 is rotatably connected in the hinge seat 14. A second servo motor 15 is fixedly installed on one side of the hinge seat 14, and the output end of the second servo motor 15 is fixedly connected to the rotating shaft of the hinge block 16 through a coupling. The second servo motor 15 is started to drive the hinge block 16 to rotate downward 90° in the hinge seat 14, so that the corn slides out through the feed port.

[0039] In order to control the lifting plate 20 to lift vertically stably, in this embodiment, a group of guide columns 22 are fixed between the upper horizontal plate 18 and the lower horizontal plate 19, and the lifting plate 20 is slidably sleeved on the side surface of the guide columns 22. A second electric push rod 21 is fixed on the lower surface of the upper horizontal plate 18, and the output end of the second electric push rod 21 is fixedly connected to the upper surface of the lifting plate 20. The lifting plate 20 can be driven to lift vertically by the second electric push rod 21, and the setting of the guide columns 22 can make the lifting plate 20 more stable when sliding up and down.
