[0024] According to the present specific embodiment, the frame 103 is fixedly connected to the top of the base 101, the lower heat sealing head 102 is fixedly connected to the base 101 and is located on one side of the frame 103, the cutting table 104 is located above the base 101 and is provided with a cutting groove, the transport assembly is located above the cutting table 104, the cutting frame 105 is fixedly connected to the top of the cutting table 104, the moving assembly is located at the top of the cutting frame 105, the cutting cylinder 106 is located below the moving assembly, the cutting knife clamp 107 is fixedly connected to the output end of the cutting cylinder 106, the cutting knife 108 is detachably connected to the bottom of the cutting knife clamp 107 by bolts, before using the device, the cutting knife 108 of the corresponding size is selected according to the width of the food packaging bag, and is installed on the cutting knife clamp 107 by bolts, and the damaged cutting knife 108 can be replaced in this way; because the positions of food packaging bags of different widths on the cutting table 104 may be different, the positions of food packaging bags of different widths on the cutting table 104 may be different. The cutting cylinder 106, the cutting knife clamp 107 and the cutting knife 108 need to be adjusted to ensure that no missed cutting occurs. The cutting cylinder 106, the cutting knife clamp 107 and the cutting knife 108 can be moved by the moving assembly to align the cutting knife 108 with the food packaging bag. Subsequently, the upper heat sealing head and the lower heat sealing head 102 of the prior art are used to extrude and heat seal the food packaging bag. After a food packaging bag is heat-sealed on the lower heat sealing head 102, the cutting cylinder 106 is started to push the cutting knife clamp 107 downward to drive the cutting knife 108 to be pressed downward to cut the food packaging bag. Subsequently, the transport assembly is started to move the food packaging bag raw material to the lower heat sealing head 102, and the cut food packaging bag is pushed out of the lower heat sealing head 102. At this time, the food packaging bag can continue to be heat-sealed and cut, thereby processing and cutting food packaging bags of different widths, shortening the working time and improving production efficiency.

[0025] Among them, the movable rail 109 is fixedly connected to the top of the cutting frame 105, the movable block 110 is slidably connected to the inside of the movable rail 109, and is provided with an installation cavity, and is fixedly connected to the cutting cylinder 106. When the cutting knife 108 is moved, the movable rail 109 provides a moving place and limits the moving direction. The movable block 110 drives the cutting knife clamp 107 and the cutting knife 108 and other components to move along the movable rail 109.
