Description

Medicine box packing device

Technical Field

The invention relates to the technical field of medicine box packaging, in particular to a medicine box packaging device.

Background

In the packaging industry, it is often appropriate to package the boxes into bundles before they are first used, i.e. to bundle the individual boxes into a stack by means of a strapping element. This packing function is typically implemented using the following machines: the machine is capable of forming bundles from boxes that have been continuously output after boxing, and then binding all the boxes of each bundle together. The purpose of this is to provide a series of bundled boxes which are then easily packaged for transport or storage. The box bundling process is to push the stacked boxes to pass through the vertically wound packaging films, at the moment, the films are wrapped on the back, the upper surface and the lower surface of the medicine box, the film pressing strip is positioned above one side of the medicine box, which is not wrapped with the films, then the film pressing strip positioned above is lowered to press the upper film onto the workbench surface, the heat sealing cutter is lifted to drive the lower film to lift and contact with the upper film, the heat sealing cutter is used for heat sealing the upper film and the lower film and then cutting off the films, so that film wrapping on four sides of the medicine box is realized, and meanwhile, the new packaging films are in a vertical bonding shape. In the bundling process, the packaging film is attached to the outer surface of the medicine box, so that the medicine box can be bundled well without influencing transportation, if the vertical packaging film is too tight, the medicine box can be easily toppled when being pushed to be wrapped, if the vertical packaging film is loose, the medicine box is not easily bundled and firm, and the heat shrinkage packaging machine can be adopted in the prior art to further attach the packaging film to the outer surface of the medicine box, so that one more working procedure is needed, and the operation is inconvenient, so that a device for preventing the medicine box from falling off randomly in the process of bundling well transportation when bundling and packaging is needed.
