The invention discloses a
thermal shrinkage film
cutting device for packing boxes. The device comprises a table body, an upper
cutting knife, an anti-sticking structure, a lower
cutting knife, an ejection structure, a fixed structure, a fixed groove, a rotating structure, support columns, grooves, a
handle, a film sticking groove and a slide chute. The
thermal shrinkage film cutting device for packing boxes has the beneficial effects as follows: when a fixed block drives an ejection block to rotate, the ejection blocks extrudes a fixed rod, the fixed rod is enabled to rotate in the table body,a compression spring shrinks to produce elastic force, the fixed rod pushes an ejection rod upwards during rotating, the ejection rod slides out of the lower cutting knife, the upper cutting knife and the lower cutting knife are contacted better, cutting of a
thermal shrinkage film is facilitated, the fixed rod is propped against the bottom end of a slide rod during continuous rotating, the sliderod is pushed upwards, the ejection rod enters the upper cutting knife from a fixed hole, a lever is pushed to rotate in the upper cutting knife, a press rod is pushed to slide out of the upper cutting knife, the press rod is enabled to push a thermal shrinkage film which is
cut between the upper cutting knife and the lower cutting knife, and the
cut thermal shrinkage film is enabled to turn downwards.
