In some embodiments, the air cylinder 420 is horizontally installed at the second bracket 120 so that the cutting knife 410 can move horizontally to keep flat when cutting the sleeve mold. In other embodiments, the cylinder 420 may also be tilted with respect to horizontal.

Referring to fig. 1, the stretching mechanism 500 extends into the opening end of the covering film 80 and stretches the covering film 80, and the stretching mechanism 500 drives the covering film 80 to move up and down, so that the covering film 80 is sleeved outside the product 90 from top to bottom.

Specifically, stretching mechanism 500 includes a support rod 510 and stretching arms 520, wherein stretching arms 520 are connected to support rod 510, and stretching arms 520 are of a stretchable structure, so that stretching arms 520 can stretch into covering film 80 from the open end of covering film 80 and stretch covering film 80, and because covering film 80 is stretchable, stretching by stretching arms 520 changes the radial dimension of covering film 80 so that covering film 80 can at least contain product 90.

In some embodiments, the radial dimension of the mantle 80 may be stretched up to 1.3 times the original radial dimension. In other embodiments, the radial dimension of the sleeve 80 may also be greater than 1.3 times the original radial dimension to meet the packaging requirements of the product 90.

In some embodiments, the number of the supporting rods 510 is four, and the four supporting rods 510 surround the product 90 with the product 90 as the center, the product 90 is a cuboid, and the four supporting rods 510 are respectively located at four opposite corners of the product 90, so as to uniformly stretch the covering film 80, and the covering film 80 is better sleeved outside the product 90.
