[0002] Pig feed packaging is an important link to ensure that the quality and safety of feed are maintained during storage, transportation and use. Common packaging materials are polyethylene and polypropylene plastic materials. These materials are moisture-proof, stretch-resistant and wear-resistant, and can effectively protect the feed from the external environment. They usually need to be lined with plastic film to prevent moisture. After the pig feed is loaded into the packaging bag, it is necessary to form a negative pressure environment by extracting the air in the bag. After sealing, the shelf life of the feed can be effectively extended and the impact of oxygen and moisture on the feed can be reduced. The feed should be stored in a dry, cool and ventilated environment to avoid direct sunlight and high temperature. The packaging bag can effectively protect the feed from moisture and oxidative environmental factors.

[0023] Working principle and use process of the present invention: Pig feed packaging is an important link to ensure that the quality and safety of feed are maintained during storage, transportation and use. Common packaging materials are polyethylene and polypropylene plastic materials. These materials have the advantages of moisture-proof, stretch-resistant and wear-resistant, and can effectively protect the feed from the external environment. Usually, a plastic film is required to be lined inside to prevent moisture. After the pig feed is loaded into the packaging bag, it is necessary to form a negative pressure environment by extracting the air in the bag. After sealing, the shelf life of the feed can be effectively extended and the influence of oxygen and moisture on the feed can be reduced. The feed should be stored in a dry, cool and ventilated environment to avoid direct sunlight and high temperature. The packaging bag can effectively protect the feed from moisture and oxidative environmental factors. The pig feed is loaded into the packaging bag 11 After the packaging bag 11 is put inside, it is often placed directly at the bottom of the sealing machine for packaging. At this time, the gap at the end of the packaging bag 11 is large, which increases the space for air to enter. The seal is easy to loosen and bubbles appear, thereby reducing the sealing effect of the packaging bag 11. External moisture and oxygen are easy to enter the packaging bag 11, affecting the quality of the feed. For this reason, a negative pressure sealing machine for pig feed packaging is designed. The packaging bag 11 is transported from a high position on the conveyor frame 2 to the surface of the shelf 9, and the packaging bag 11 is stretched upward manually. The packaging bag 11 is unfolded by two opening devices 4, and the pig feed in the storage cylinder 5 is guided to the internal storage of the packaging bag 11. After the micro motor 12 is started, the gear 13 connected to its output shaft is driven to rotate. Since the gear 13 is meshed with the straight rack 10 Then, under the connection of the moving plate 8, the moving block 7 is driven to move at one end of the bottom rod 6, thereby driving the placing table 9 to move toward the bottom of the sealing frame 17. After the packaging bag 11 is moved close to the binding plate 16, the binding plate 16 moves at one end of the fixing rod 14. The binding plate 16 can block the packaging bag 11 to prevent the pig feed in the packaging bag 11 from tipping over and spilling out. After the packaging bag 11 reaches the bottom of the first support frame 25 and the second support frame 29, the pushing plate 28 is pushed inward. Under the connection of the extension rod 27, the contact block 23 is driven to move at one end of the cross bar 22, which also drives the first support frame 25 gradually close to the second support frame 29. The multiple first clamping wheels 26 and the multiple second clamping wheels 30 respectively clamp the packaging bag 11 The two sides are pressed tightly. Pressing the ends of the packaging bag 11 helps to ensure that the bag mouth is tightly closed, reduce air entry, and ensure that there is no looseness and bubbles at the seal, thereby improving the sealing effect and preventing external moisture and oxygen from entering the packaging bag 11. The sealing strip and the control panel cooperate to transport the packaging bag 11 with the ends pressed to the bottom of the heating and sealing device 21. At the same time, the vacuum pump 20 and the control panel are started to clamp the ends of the packaging bag 11 in the heating and sealing device 21. The vacuum pump 20 is used to extract the air inside the packaging bag 11 to form a negative pressure environment. The temperature of the heating tube in the heating and sealing device 21 increases. In this way, the sealed parts of the packaging bag 11 are bonded together to complete the sealing. The control panel is used to set the sealing temperature, time and negative pressure value.
