Description
Technical Field
The present utility model relates to a cutting device for cutting packaging films, which is intended to be mounted on a wrapping and packaging machine, in particular on a wrapping and packaging machine for packaging trays and the like or other articles requiring a hot-cutting film device.
Background
The pallet is a substantially flat structure, typically made of wood, on which goods are placed to simplify storage and transport of the goods. However, the "towers" of the goods stacked on top of the pallet are not only unprotected, but also tend to be quite unstable.
In order to solve the above problems, a pallet winding machine is now used, specifically, a winding machine winds an elastically extensible film around a pallet and goods, which can wrap and shape the goods, and stably fix the goods at the same time.
The tray winding machines of different types are provided, so that different production requirements of enterprises can be met. In this respect, the automatic winding machine is capable of automatically winding the packaged goods, but also of independently cutting the final edge of the film at the end of the packaging and then welding it. Therefore, it is common to place the product at the end of the production line, directly connected to the machine that palletizes the product.
In this type of winding machine, the cutting is performed by a cutting device equipped with a support element and a cutting element, which stretches the packaging film and holds it in place.
It is particularly notable that conventional winding machines use an electrically heated resistance wire that, with direct contact with the wound film, is cut according to a predetermined line.
However, such cutting techniques as described above allow residues that may be present to remain on the wire and reduce its cutting ability as they accumulate, so that replacement of this wire is necessary.
Furthermore, the direct contact between the hot wire and the wound film gives off a smell which is very unpleasant for the operator during the cutting operation.
In view of the above-mentioned circumstances, it is apparent that the above-listed drawbacks relate not only to existing pallet winding machines, but more generally to all winding devices that cut the wound film by a direct contact thermal cutting method.
It is therefore desirable to be able to retrofit existing wound film cutting devices, as well as to retrofit existing winding devices with wound films or films that remain on objects (e.g., pallets); in particular, it is desirable to provide a solution that can guarantee high cutting performance as well as long lasting efficient operation.

It is a further object of the present utility model to provide a set of high performance cutting devices with high cutting capability and good cutting results.

Preferably, the primary support element and the secondary support element each have a respective portion of the outer surface, the two portions together defining a support plane, the film being located inside the support plane during the cutting operation.
Preferably, the primary support element has a primary longitudinal development axis and the secondary support element has a secondary longitudinal development axis, the primary and secondary longitudinal development axes being parallel to each other.
Preferably, the thermally activated cutting element has a further longitudinal development axis parallel to the primary and secondary longitudinal development axes, corresponding to the primary and secondary support elements, respectively.
Preferably, the thermally activated cutting element is parallel to the support plane.
Preferably, the thermally activated cutting element is placed at a distance from the support plane.
Preferably, the length of the primary and secondary support elements extending longitudinally along the respective primary and secondary longitudinal axes of development is equal to or greater than the width of the film along the primary and secondary longitudinal axes of development, so that the film can be supported on the primary and secondary support elements along its entire width.
Preferably, the length of the thermally activated cutting element extending along the respective further longitudinal development axis is equal to or greater than the width of the film along the further longitudinal development axis, so that the complete cutting of the film is completed by one cutting operation.
Preferably, the primary and secondary support elements are roll-back, round steel or profiled steel.
Preferably, the thermally activated cutting element is a thermally activated wire.

FIG. 2 is a perspective view of the cutting device of FIG. 1 with a wrapping film to be cut thereon;

Detailed Description
The general features of the utility model will be illustrated by way of exemplary and non-limiting embodiments in the following appendix.
The cutting device 10 is described below with reference to the accompanying drawings.
The cutting device 10 is mounted on the device a for winding objects, in particular trays P, through the film F, on the device a, as shown in fig. 4.
It is particularly notable that the device a is configured for winding the tray P by means of an elastic winding film F.
Referring to fig. 1 and 2, the cutting device 10 is provided with a thermally activated cutting element 11 for cutting the wrapping film F in a clear and precise manner.
The cutting device 10 comprises a main support element 12 for supporting the film F. The main support element 12 is located at the proximal end of the cutting element 11.
The cutting device 10 is furthermore provided with a secondary support element 13 for supporting the film F at the proximal end of the cutting element 11.
It is particularly notable that the secondary support element 13 is designed so that the cutting element 11 can be placed between the primary support element 12 and the secondary support element 13; as shown in fig. 2, these two have respective portions of the external surface 14, 15 which together define a supporting plane, inside which the film F is positioned during the cutting operation. For example, the support elements 12, 13 may be return rollers. According to other versions not shown, the support elements 12, 13 may comprise round steel, profiled steel or other desired elements.
The support elements 12, 13 are designed to prevent the film F from coming into contact with the cutting element 11. In other words, according to the cutting device 10 of the present utility model, it is possible to ensure a pull-apart distance between the film F and the cutting member 11.
Referring to fig. 1, the cutting element 11 has a further longitudinal development axis Y1 which is parallel both to the main longitudinal development axis Y2 of the main support element 12 and to the secondary longitudinal development axis Y3 of the secondary support element 13. In this way, the support plane is parallel to the cutting element 11. For example, the cutting element 11 may have a heat activated wire tensioned by tensioning means 16, 17.
Furthermore, as can be seen more clearly in fig. 3, the cutting element 11 is placed at a distance d from the support plane, and once the thermally activated cutting element 11 has become hot, the film F is cut by heat radiation. In this way, the cutting operation is performed without the need to bring the cutting element 11 into direct contact with the film F. Thanks to this configuration, it is possible to avoid possible residues remaining on the cutting element 11 and to reduce its cutting capacity as it accumulates continuously.
As shown in fig. 2, the cutting member 11 extends along the additional longitudinal development axis Y1 for a length equal to or greater than the width L of the film F along this additional longitudinal development axis Y1, so that the complete cutting of the film F is completed by one cutting operation. In the same way, the support elements 12, 13 extend longitudinally along the main longitudinal development axis Y2, respectively the secondary longitudinal development axis Y3, by a length equal to or greater than the width L of the film F along the main longitudinal development axis Y2 and along the secondary longitudinal development axis Y3, respectively, so as to enable the film F to be supported on the support elements 12, 13 along their entire width and thus inside the above-mentioned support planes.
Thanks to the features described above, the cutting device 10 not only has a high cutting capacity and efficiency, but also ensures that this cutting capacity is continuously available over time, thus also extending the operational life of the cutting element 11. Furthermore, the occurrence of unpleasant odours during the cutting operation is suppressed or at least very significantly reduced, since contact of the film F with the thermally activated cutting element 11 is avoided.
As is evident from the above, the cutting device according to the present utility model successfully achieves all the preset aims previously mentioned.
The description and illustrations in the figures are provided for the purpose of illustrating the innovative functioning of the cutting device.
Indeed, the materials, so long as they are compatible with the specific use, as well as the individual components of each, may be appropriately selected according to the requirements and the state of the art available. Modifications and/or additions may be made to the description and illustrations of the drawings.
