Description

Hot melting knife of laminating equipment

Technical Field

The utility model relates to a laminating equipment, in particular to laminating equipment's hot melt sword.

Background

The film coating equipment is special equipment for coating films on paper, paperboard and other articles. In the film coating process, the film fed out from the roll is cut by a hot cutting tool. The conventional hot cutting tool mainly comprises a rotatable cutter shaft, a hot-melting cutter mounted on the cutter shaft and a heating element for heating the hot-melting cutter, wherein the cutter shaft is driven to rotate by a driving motor.

The length adaptation of traditional hot melt sword and arbor, the horizontal both sides of hot melt sword are seted up flutedly respectively, and heating element is for inlaying the electric heat module of locating in the hot melt sword recess. In the use process, the electric heating module conducts heat energy to the hot-melting cutter after being electrified, so that the hot-melting cutter has corresponding heat energy to carry out hot cutting on the film. However, after the whole hot-melting knife is fixed with the knife shaft, more or less thermal deformation occurs in the heating process, the hot-melting knife is bent due to long-term thermal deformation and changes from the original straight shape into an arc shape, at the moment, the hot-melting knife only has an arc top at the knife edge to implement hot cutting, a thin film cannot be cut off in the hot cutting process, and the film laminating equipment needs to be stopped to replace the hot-melting knife. Not only is production hindered, but also the maintenance and replacement costs are high.

Disclosure of Invention

Not enough to prior art exists, the utility model provides a hot melt sword of laminating equipment that is difficult for thermal deformation, simple structure.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a laminating equipment's hot melt sword, is including the cutter body that has cutting edge and installation department, its characterized in that: the cutter bodies are arranged in a straight shape and spliced mutually and comprise a plurality of sections, and each cutter body is buckled with the cutter body mutually.

By adopting the technical scheme, the hot-melting knife is formed by splicing a plurality of sections of knife bodies, and the knife bodies are mutually buckled, so that the length of the knife bodies is shortened, when the knife bodies are heated by the heating element, the knife bodies are butted with the knife bodies buckled by the knife bodies at two axial ends, and arc deformation cannot occur, so that the straightness of the cutting edge of the hot-melting knife is ensured, the hot-melting knife can be continuously used for hot cutting of a film, the normal production is ensured, and the maintenance and production cost is reduced.

The utility model discloses further set up to: the cutter bodies of all the sections are connected through dovetail blocks and dovetail grooves.

By adopting the technical scheme, the connecting structure is simple, the processing is convenient, and the cutter body can not fall off after being connected.

The utility model discloses further set up to: each section of cutter body is respectively provided with a mounting hole for installing a heating source along the axial direction, and the mounting hole is arranged close to the cutting edge.

By adopting the technical scheme, the installation of the heating source and the cutter body is convenient, the heating source is stable and quick in heat conduction at the cutting edge, and the hot-melting cutter can be quickly heated, so that the quick hot cutting of the film is ensured.

The utility model discloses further set up to: the knife edge is arranged in a triangular shape.

Adopt above-mentioned technical scheme, the setting is so that the cutting edge of cutter body can be heated fast, also can avoid the loss of heat energy simultaneously.

The present invention will be further described with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

FIG. 2 is an enlarged view of section I of FIG. 1;

fig. 3 is a schematic sectional view taken along line a-a of fig. 1.

Detailed Description

Fig. 1-3 show a hot melt cutter of laminating equipment, including the cutter body 1 that has cutting edge 11 and installation department 12, including a plurality of sections be straight form arrange and the cutter body 1 of mutual concatenation, each cutter body 1 and the mutual lock between the cutter body 1. Among the above-mentioned scheme, set up the hot melt sword into by the shaping of a plurality of sections cutter body 1 concatenation, and each mutual lock between the cutter body 1, the length of cutter body 1 has been shortened in the setting like this, when heating element implements the heating to cutter body 1, each cutter body 1 receives the conflict of axial both ends rather than lock cutter body 1, can not take place the arcuation and warp, thereby guaranteed the straightness of hot melt sword cutting edge department, impel this hot melt sword sustainable to implement the hot cut to the film, guaranteed the normal clear of production, the maintenance and manufacturing cost are reduced.

In the embodiment of the present invention, the cutter body 1 and the cutter body 1 after being connected can not be detached. The cutter bodies 1 of all the sections are connected through dovetail blocks 13 and dovetail grooves 14 respectively. Of course, the knife body 1 and the knife body 1 can also be connected through a rectangular clamping block and a rectangular clamping groove, or through a fastener, and the connection is also feasible.

In order to facilitate the installation of the heating source and the cutter body 1, the heat conductivity of the heating source to the cutting edge 11 is stable and quick, the hot melting cutter can be quickly heated, and the quick hot cutting of the film is ensured. Each section of the cutter body 1 is provided with a mounting hole 15 along the axial direction thereof, and the mounting hole 15 is arranged close to the cutting edge 11. The shape of the mounting hole 15 may be set according to the shape of the heat generating source. The blade 11 of the cutter body 1 is arranged in a triangular shape. This is provided in order that the cutting edge 11 of the cutter body 1 can be heated quickly and at the same time the loss of heat energy can be avoided.
