The spring 7 is subjected to force and generates a rebound force. After the force disappears, the rebound generates power to drive the limit block 6 to move, thereby realizing the rapid disassembly of the heat strip 3, which can significantly reduce the time required for replacing parts, thereby reducing the downtime of the production line, improving production efficiency and reducing production costs, and reducing the labor intensity of staff. Regular replacement of the heat strip can ensure that the sealing quality and vacuum effect are consistent, which is crucial to food quality and food preservation, and extends the shelf life of food.

[0023] Reference Figure 1-3 A cavity 2 10 is provided inside the bottom plate 1, and a motor 11 is fixedly connected to one side of the cavity 2 10. A gear 12 is fixedly connected to the driving end of the motor 11. An exhaust pipe 13 is slidably connected to the inside of the front end of the bottom plate 1, and the bottom end of the exhaust pipe 13 is fixedly connected to a rack plate 14. The rear end of the exhaust pipe 13 is fixedly connected to a negative pressure component, and the negative pressure component includes a delivery pipe 15, and the rear end of the delivery pipe 15 is fixedly connected to a vacuum pump. The front end of the delivery pipe 15 is fixedly connected to the rear end of the exhaust pipe 13. A heat sealing layer 16 is fixedly connected to the top end of the front side of the bottom plate 1, and the bottom end of the heat strip 3 contacts the top end of the heat sealing layer 16 to achieve sealing of the packaging bag. A handle 17 is fixedly connected to the top end of the top plate 2 to achieve the movement of the suction nozzle. By moving the suction nozzle, the gas can be more comprehensively sucked out to ensure that the atmosphere around the food is effectively eliminated, thereby improving the overall practicality.

[0024] Working principle: First, the heating strip 3 is quickly disassembled. First, the support rod 8 is pulled. Under the pulling of the support rod 8, the sliding block 5 is driven to move. Then, the movement of the sliding block 5 drives the limit block 6 to move. Then, the spring 7 is subjected to force under the movement of the limit block 6. Under the force of the spring 7, a rebound force is generated to offset the force received. Then, under the outward movement of the sliding block 5, the sliding block 5 and the long hole 9 are separated, so that the heating strip 3 can be quickly disassembled. At this time, the support rod 8 is released. Under the rebound force generated by the spring 7, the spring 7 rebounds. Under the rebound of the spring 7, the limit block 6 is driven to move back, and then the spring 7 is driven to move and engage with the long hole 9, so that the heating strip 3 can be quickly installed. Then, the opening of the packaging bag is placed on the heat-sealing layer 16 and put on the exhaust pipe 13. At this time, the air in the packaging bag is sucked away by starting the exhaust pipe 13. At this time, the motor 11 is started, and the gear 12 is driven by the motor 11 to move. The rack plate 14 is driven to move under the movement of the gear 12, and then the exhaust pipe 13 is driven to move, so as to move the exhaust pipe 13 back and forth. When the exhaust pipe 13 moves to the inside of the cavity 2 10, the handle 17 is pressed to prevent the exhaust pipe 13 from being pressed under the movement of the heat strip 3. The top plate 2 is driven to move under the movement of the handle 17, and then the heat strip 3 is driven to move downward under the movement of the top plate 2 to contact the heat-sealing layer 16 to achieve sealing of the packaging bag.
