[0025] Please refer to Figures 1-4 The upper end of the workbench 1 is provided with the sealing ring 13, and the upper end of the workbench 1 is connected with the guide rod 110.

[0026] In this way, the end of the corn packaging bag is inserted into the material limiting groove 23 and tightly attached to the pressure receiving strip 16, the hydraulic cylinder 11 is started to drive the gland 12 to compress the sealing ring 13 on the workbench 1, the heat sealing strip 15 is driven to compress the end of the corn packaging bag on the pressure receiving strip 16, the vacuum pump 32 is started to extract the air in the gland 12 and the corn packaging bag to make it vacuum, and the heat sealing strip 15 is started to heat seal the end of the corn packaging bag.

[0027] Please refer to Figures 1-4 The upper end of the workbench 1 is connected with the spring 17, and the inside of the support sleeve 18 is slidably sleeved with the guide rod 110.

[0028] In this way, the design of the spring 17 can buffer the compression of the heat sealing strip 15 on the pressure receiving strip 16, prevent the heat sealing strip 15 from being damaged by extruding the pressure receiving strip 16, and the design of the limiting block 19 can limit the movement range of the support sleeve 18 to prevent the support sleeve 18 from slipping off.

[0029] Please refer to Figure 2 And Figure 5The upper end face of the workbench 1 is slidably connected to a U-shaped block 22, and the upper end face of the workbench 1 is slidably connected to a support block 24.

[0030] With this setup, by moving the U-shaped block 22 laterally, the slider 21 and support block 24 can be moved laterally, and the position of the U-shaped block 22 can be adjusted so that the U-shaped block 22 passively pushes the corn to the bottom of the corn packaging bag for sealing.

[0031] Please see Figure 1 , Figure 2 and Figure 5 The lower end of bolt 25 is pressed against the workbench 1. A vacuum mechanism is installed at the lower end of the workbench 1. The vacuum mechanism is used to extract the gas inside the corn packaging bag to make it a vacuum. The vacuum mechanism includes a power cabinet 3 installed at the lower end of the workbench 1. The power cabinet 3 is provided with heat dissipation holes 31. A vacuum pump 32 is installed inside the power cabinet 3. One end of the vacuum pump 32 is connected to a connecting pipe 33. The vacuum pump 32 is mainly responsible for extracting the gas inside the container and packaging bag to form a vacuum state. That is, when the vacuum chamber is closed, the vacuum pump 32 starts to work. Through the negative pressure generated by the operation, the gas inside the test-sealed bag is extracted, and various gases are discharged at the same time, so that the inside of the bag presents a vacuum state until the rated vacuum degree is reached. A connecting pipe 33 is installed inside the workbench 1 and the power cabinet 3.

[0032] In this setup, by rotating the tightening bolt 25 to press the worktable 1, the slider 21 is driven to press the worktable 1 upward, thereby fixing the position of the U-shaped block 22 and preventing it from sliding and moving automatically during processing. The slider 21 is designed to guide the movement of the U-shaped block 22 and prevent lateral deviation from affecting the sealing of the corn packaging bag.

[0033] The working principle of this embodiment is as follows: When using the pressing structure of this fresh corn vacuum packaging machine, fresh corn is put into the corn packaging bag. The end of the corn packaging bag is inserted into the limiting groove 23 and pulled to one end, so that the U-shaped block 22 passively pushes the corn to the bottom of the corn packaging bag. The end of the corn packaging bag to be sealed is tightly attached to the pressure strip 16. The hydraulic cylinder 11 is started to drive the pressure cover 12 to press the sealing ring 13 on the worktable 1, and drive the heat sealing strip 15 to press the end of the corn packaging bag to the pressure strip 16. The vacuum pump 32 is started to extract the air from the pressure cover 12 and the corn packaging bag to make it a vacuum. The heat sealing strip 15 is started. Under vacuum, the packaging bag is sealed by heat sealing. Heat is generated during the sealing process, which makes the opening of the packaging bag fuse together, forming a vacuum chamber isolated from the outside world, so that the end of the corn packaging bag can be heat sealed.

[0034] It is worth noting that the design of the spring 17 can buffer the pressure of the heat sealing strip 15 on the pressure receiving strip 16, preventing the heat sealing strip 15 from squeezing and damaging the pressure receiving strip 16, and the design of the limiting block 19 can limit the movement range of the support sleeve 18, preventing the support sleeve 18 from slipping off.

[0035] By moving the U-shaped block 22 to drive the slider 21 and the supporting block 24 to move laterally, the position of the U-shaped block 22 can be adjusted, so that the U-shaped block 22 passively pushes the corn at the bottom of the corn packaging bag to seal the bag. By rotating the tightening bolt 25 to press the workbench 1, the slider 21 is driven to press the workbench 1 upwards, so as to fix the position of the U-shaped block 22 and prevent it from moving automatically during processing. The design of the slider 21 can guide the movement of the U-shaped block 22 and prevent side deviation from affecting the sealing processing of the corn packaging bag.

[0036] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
