The lifting rod 2 is supported on the bearing hole of the bearing seat 5. The upper end of the lifting rod 2 is connected to the lifting frame 1, and the lower end of the lifting rod 2 is connected to the chain 9.
[0024] The lifting frame 1 is the main component that supports the food vacuum packaging bag. Its design must have sufficient strength and stability to ensure that the packaging bag is not damaged during the lifting process. The up and down movement of the lifting frame 1 allows the packaging bag to be smoothly immersed in and removed from the hot water in the water tank, completing the sterilization and shrinkage process.
[0025] In practice, the lifting frame 1 can be made of stainless steel to resist corrosion and high temperatures.
[0026] Water tank 6 serves as the heat transfer medium between the heating device and the packaging bags; its capacity must be rationally designed based on production efficiency and packaging bag size. The interior of the water tank should be kept clean to avoid contaminating the food packaging bags.
[0027] In practice, the bottom of water tank 6 can be designed as a flat bottom or a conical bottom to facilitate drainage and maintenance.
[0028] The housing 7 is a crucial component protecting the internal structure and ensuring operational safety of the equipment, while also providing heat and sound insulation. It should be noted that the housing design must facilitate maintenance and repair.
[0029] In practice, the casing 7 can be made of stainless steel to improve the durability and safety of the equipment.
[0030] The heating device is responsible for heating the water in the tank to the set sterilization temperature. The heating efficiency and the accuracy of temperature control directly affect the sterilization effect and energy consumption.
[0031] In practice, heating devices include electric heating rods, steam heaters, etc., and the appropriate heating method is selected according to production needs.
[0032] The lifting device is a key component for realizing the up-and-down movement of the lifting frame, and its performance directly affects the sterilization effect of the packaging bag and the operational stability of the equipment.
[0033] In practice, the lifting device includes a lifting rod, a driven sprocket, a bearing housing, a chain, a drive sprocket, and a motor. The lifting rod, supported by bearing holes in the bearing housing, connects to the lifting frame, enabling vertical movement. The driven sprocket and drive sprocket are driven by a chain, transmitting power from the motor to the lifting rod. The bearing housing supports the lifting rod, ensuring its stable operation. The chain transmits power, connecting the lifting rod and the sprocket. The motor provides the power source, driving the movement of the lifting frame through the sprocket and chain transmission mechanism.
[0034] To facilitate the adjustment of the length of the chain 9, an upper tensioning block and a lower tensioning block are provided at both ends of the chain 9. A lifting rod connecting plate is provided at the lower end of the lifting rod 2, and the upper tensioning block and the lower tensioning block are connected to the lifting rod connecting plate.
[0035] In specific implementation, the food packaging bag sterilization and shrinking machine of this utility model also includes a lifting limit control device, which includes an upper limit switch 11, a position limit switch piece 13 and a lower limit switch.

[0036] The lifting frame 1 is equipped with multiple drainage holes. When the lifting frame is raised to discharge material, the residual water left on the lifting frame can be promptly drained back into the water tank through the drainage holes.
[0037] Rollers are provided between the lifting frame 1 and the water tank 6. The rollers are fixed on the lifting frame 1 to facilitate the up and down movement of the lifting frame and enhance the support of the lifting rod.
[0038] In some alternative implementations, the food packaging bag sterilization and shrink wrapping machine of this invention may also include a temperature sensor. The temperature sensor is installed inside the water tank to monitor the water temperature in real time, ensuring that the heating device can heat the water to the set sterilization temperature, and adjusting the heating power promptly when the temperature fluctuates to maintain temperature stability. By using a temperature sensor, the accuracy and stability of the sterilization temperature can be improved, and energy consumption can be reduced.
[0039] In some alternative implementations, the food packaging bag sterilization and shrink wrapping machine of this utility model may also include a circulation pump and a filter. The circulation pump is installed at the bottom of the water tank and connected to the water tank and filter through a pipe to form a circulation loop. By using a circulation pump and a filter, the circulation flow of water in the water tank can be promoted, improving heating efficiency and sterilization uniformity; the filter is responsible for removing impurities and particulate matter from the water, keeping the water quality clean; enhancing the sterilization effect and extending the service life of the equipment.
[0040] In some optional implementations, the food packaging bag sterilization and shrink wrapping machine of this utility model may also include an ultraviolet germicidal lamp. The ultraviolet germicidal lamp is installed inside the water tank or at the water outlet and fixed by a bracket. Utilizing the sterilizing effect of ultraviolet light, the packaging bags are subjected to secondary sterilization after sterilization treatment, ensuring a more thorough sterilization effect; improving sterilization efficiency and reducing food safety risks.
[0041] In some alternative implementations, the food packaging bag sterilization and shrink wrapping machine of this utility model may also include an insulation layer. The insulation layer wraps around the water tank and the outside of the machine casing and is fixed by bolts or glue.

The automatic drain valve is installed at the bottom of the water tank, and the water replenishment system is connected to the water tank through a pipe and controlled by a solenoid valve. By using the automatic drain valve and water replenishment system, old water in the water tank can be periodically drained and new water can be automatically replenished to keep the water fresh and clean; this avoids water quality deterioration from affecting the sterilization effect and improves the continuity and stability of equipment operation.
[0043] In some alternative implementations, the food packaging bag sterilization and shrink wrapping machine of this utility model may also include a pressure sensor and an alarm system. The pressure sensor is installed inside the water tank or on related pipelines and is connected to the alarm system via a cable. By using the pressure sensor and alarm system, pressure changes in the water tank can be monitored in real time. When the pressure exceeds the set value, the alarm system sounds an alarm to remind the operator to handle the situation promptly; this can prevent equipment failures and safety accidents, and improve the safety and reliability of equipment operation.
[0044] The working principle of this food packaging bag sterilization and shrink-up machine is as follows:
[0045] The heating device 8 first heats the water medium in the water tank 6. After heating to the required temperature, the motor 12 is started. The motor 12 drives the lifting frame 1 to move downward through the sprocket and chain transmission device, bringing the food vacuum packaging bag placed on the lifting frame 1 into the water tank 6. The motor 12 stops rotating when the limit switch 13 contacts the lower limit switch 11. Then, the hot water sterilizes the food vacuum packaging and smooths the surface wrinkles of the packaging bag. After a few seconds, the motor 12 reverses, and the lifting frame 1 rises with the food vacuum packaging bag until the limit switch 13 contacts the upper limit switch 14. The motor 12 stops rotating, and the residual water left on the lifting frame is drained back into the water tank through the drain hole 15. The food vacuum packaging bag is discharged, completing one batch of work.
