[0002] A packaging bag refers to a bag used to package various supplies, which makes it convenient to transport and store goods during the production and circulation process. It is widely used in daily life and industrial production. When sealing the packaging bag, the object needs to be stuffed into the hollow bag body first, and then it is heat-pressed and sealed for subsequent storage and use; some existing packaging bag sealing mechanisms drive the sealing part of the packaging bag to move and seal through the extrusion between guide rollers, but due to the lack of a limiting structure during the extrusion and movement process, the packaging bag may be offset and tilted, which is not conducive to the sealing operation, and the packaging bag cannot be corrected to make it vertically correspond to the hot pressing block, affecting the sealing effect of the packaging bag. Utility Model Content

[0025] The use method of the utility model is as follows: when performing the sealing operation of the packaging bag, the staff can place the packaging bag to be sealed on the left side of the conveyor belt 500, and make the sealing point correspond to the back side of the workbench 100. The staff can start the first electric push rod 301 to make the baffle 302 move back and forth to adjust the distance between the sealing point of the packaging bag and the bottom plate 403, which is convenient for the correspondence between the sealing point of the packaging bag and the bottom plate 403 during the sealing operation. Under the connection action of the fixed rod 303, the slider 305 will move in the slide groove 304, ensuring the smooth movement of the baffle 302 and providing a supporting effect for the baffle 302. After that, the staff can start the second electric push rod 307 to make the connecting plate 308 move downward to block the packaging bag on the left side. Since the baffle 302 corresponds vertically to the connecting plate 308, It can prevent the packaging bag from being offset and tilted during the sealing operation. Then the staff can start the third electric push rod 401 to press the hot pressing block 402 downward to perform hot pressing and sealing on the packaging bag, and then move the connecting plate 308 upward. The hot pressed packaging bag moves to the right through the conveyor belt 500. Then the staff can start the fan 602 to blow air into the ventilation duct 601 and blow it out through the air outlet 603 to dissipate the heat of the packaging bag that has just been hot pressed and sealed, so as to prevent the packaging bag from being deformed due to long-term heat after hot pressing. Then the packaging bag is discharged through the discharge plate 800. The utility model can not only limit the packaging bag to prevent the packaging bag from being offset and tilted, but also correct the packaging bag to make it vertically correspond to the hot pressing block 402, thereby ensuring the sealing effect of the packaging bag.
