Under the blocking effect of the limiting surface and the slide 230, the translation of the plastic film is limited to avoid the misalignment of the heat-sealing edge during the hot air process. When it is necessary to replace plastic films of different widths, the position of the slide 230 can be adjusted so that the distance between the slide 230 and the limiting surface can adapt to plastic films of different widths. This increases the applicable range of the adjustable former.

[0035] In some preferred embodiments, the slide bar 220 has a scale set along its length direction. The operator can understand the distance between the slide seat 230 and the limit surface according to the scale on the slide bar 220, so that the distance between the slide seat 230 and the limit surface matches the plastic film width.

[0036] In addition, an embodiment of the utility model also provides a food packaging machine, which is equipped with the above-mentioned adjustable former.

[0037] By adjusting the installation position of the connecting plate 120, the height of the connecting plate 120 can be adjusted to change the distance between the guide gap and the heat sealing roller.
