Description

Technical Field

[0001] The utility model relates to the technical field of hot-pressing sealing devices, in particular to a hot-pressing sealing device for packaging bags. Background Art

[0002] The hot-pressing sealing device for packaging bags is a key equipment in modern packaging technology. It uses the principle of electric heating to melt the packaging bag material through pressure, and then cools and solidifies it to achieve sealing. The device mainly includes heating elements, pressure systems and control systems to ensure that the seal is firm, moisture-proof and leak-proof. It is suitable for various packaging materials such as plastic films and is widely used in food, medicine and other industries. Its efficient and precise sealing performance improves the quality and safety of product packaging.

[0003] When the device is actually used, due to the lack of an integrated air extrusion structure, air still remains in the sealed packaging bag. Since there are bacteria and microorganisms in the air, it is easy to accelerate the deterioration of food, thereby shortening the storage time of food. Based on these problems, Chinese patent CN220181261U discloses a hot-pressing sealing device for rice noodle packaging bags. The utility model drives a bevel gear 1 on one side to rotate by a double-axis motor, and utilizes the meshing action between the bevel gear 1 and the bevel gear 2 to drive the turntable to rotate, and the rotation of the turntable drives the column to rotate. Through the active cooperation of the column and the rectangular frame, the piston plate is driven to move horizontally back and forth in the air extraction chamber, so as to facilitate the inflation of the airbag. As the airbag continues to expand, the packaging bag can be squeezed to discharge the air inside it, effectively avoiding the problem that the air remaining in the sealed packaging bag is quickly discharged due to the lack of an integrated air extrusion structure, thereby slowing down the deterioration of food and further extending the storage time of food.

[0004] The device mainly uses extrusion to expel the air in the rice noodle packaging bag. After the rice noodles are bagged, the strips of rice noodles will be piled together irregularly. At this time, there are large or small gaps between the rice noodles. Therefore, relying on the extrusion exhaust method, not only can the air in the rice noodle packaging bag not be completely discharged, but the rice noodles will also be damaged, which seriously affects the use effect of the sealing device.
