The mounting plate 21 is fixedly connected to the bottom of the driving assembly. Round blocks 24 are fixedly installed on the front sides of both ends of the mounting plate 21. A long plate 25 is movably sleeved on the outer side of the round block 24. A pressing wheel 26 is fixedly installed below the long plate 25. Rectangular blocks 29 are fixedly installed on the front sides of both ends of the mounting plate 21, and a telescopic spring 30 is elastically installed between the lower side of the rectangular block 29 and the upper side of the long plate 25.

[0034] When the packaging bag needs to be heat-sealed, the driving assembly is started to drive the mounting plate 21 to move downward, the mounting plate 21 drives the round block 24 to move downward, the round block 24 drives the long plate 25 to move downward, the long plate 25 drives the pressing wheel 26 to move downward and contact the packaging bag, the pressing wheel 26 is squeezed by the long plate 25 to rotate around the round block 24 and move outward to squeeze the telescopic spring 30, thereby applying elastic force to eliminate wrinkles in the packaging bag.

[0035] By starting the driving assembly, the mounting plate 21 is driven to move downward, so that the pressing wheel 26 contacts the packaging bag, driving the long plate 25 to rotate and move outward around the round block 24, squeezing the telescopic spring 30. The telescopic spring 30 releases elastic potential energy to push the pressing wheel 26 to move on the surface of the packaging bag. Compared with the traditional heat sealing machine for PE packaging bag processing, this PE packaging bag processing heat sealing machine eliminates wrinkles by moving the pressing wheel 26 on the surface of the packaging bag, thereby improving the sealing quality of the packaging bag.
