Description

The film cutting apparatus of three-dimensional packaging machine

[technical field]

The utility model relates to a kind of similar cigarette case 3 D transparent film packing machine equipment, in particular the film cutting apparatus on the three-dimensional packaging machine.

[background technology]

At present, the film cutting apparatus that uses on the three-dimensional packaging machine, as shown in Figure 1, this film cutting apparatus also is made of cutter shaft 15, knife rest 11 and rotor 14, described cutter shaft 15 is installed on the knife rest 11, and rotor 14 is installed on the cutter shaft 15, and this rotor 14 also is sharp rotor, tool rest 13 also is installed on knife rest 11, on tool rest 13, is fixed with a dead knife 12.This film cutting apparatus will lean on the rotation of cutter shaft 15, drive sharp rotor 14, could cut off hyaline membrane (BOPP film) when making sharp rotor 14 with dead knife 12 wipe contacts, there is not the gap between its sharp rotor 14 and the dead knife 12, and slightly interference, thereby sharp rotor 14 is in cutting the process of film, wearing and tearing easily, and noise is big during contact.Need often sharp rotor 14 to be whetted a knife, and will often adjust the magnitude of interference of sharp rotor 14 and dead knife 12, its troublesome poeration, simultaneously, its magnitude of interference also is difficult for adjusting.Look into Chinese patent, its publication number is CN2048845U, name is called " a kind of notching device of wrapping machine envelope " and discloses following content: a kind of notching device of wrapping machine envelope, be by the roller driving system, parts such as a pair of vertically sealed roller and cutting knife pair are formed, it is characterized in that: said a pair of vertically sealed roller is the arc roll surface that keeps symmetry along cylindrical axis parallel cut-out, roller end is two shapes and big or small identical of concentric external incorporate roll shaft again, roll surface rotates the vertically sealed roller of pressing relatively, fixedly is pasted with the cutting knife pair again on the roll body of the same side of roll surface.From the specification sheets of this patent application and accompanying drawing thereof as can be known, the secondary part of its cutting knife of this notching device is attached on the roll body, and is provided with in the part of roll body, thereby, the firmness of cutting knife pair is not enough, the otch that can only be used for less envelope, for the BOPP film, it is long to want to cut off width, then be at a complete loss as to what to do with this notching device, this otch is used to cut envelope simultaneously, needs certain temperature, and this also is not suitable for for the BOPP film.

[utility model content]

In view of the problem that background technology exists, the technical problems to be solved in the utility model provides a kind of can the cut-out hyaline membrane, and the not easy to wear and noiselessness of cutter is applied in the film cutting apparatus of similar cigarette case three-dimensional packaging machine.

For solving the problems of the technologies described above, the utility model takes following technical scheme to realize: a kind of film cutting apparatus of three-dimensional packaging machine, has knife rest, cutter shaft and rotor, described cutter shaft is installed on the knife rest, described rotor is installed on the cutter shaft, it is characterized in that described cutter shaft has first cutter shaft and second cutter shaft, described first cutter shaft is relative with second cutter shaft to be rotated, described rotor has the cutter of flatting turn and sharp rotor, the cutter of flatting turn is installed on first cutter shaft, sharp rotor is installed on second cutter shaft, described sharp rotor peace rotor is provided with on first cutter shaft and second cutter shaft vertically, and extend on the whole axial plane of first cutter shaft and second cutter shaft, described cutter and the sharp rotor of flatting turn is in contact with one another when cutting film; Described first cutter shaft and second cutter shaft are provided with elongated slot, and described cutter and the sharp rotor of flatting turn places this elongated slot respectively, and is fixed; The cutting edge of the described cutter of flatting turn is a circular arc shaped; The cutting edge cross section of described sharp rotor is horn shape.

After the utility model adopts double-pole axle construction, not friction relatively between its sharp rotor peace rotor, thereby not wearing and tearing between them, long service life, and noiselessness can be cut off roomy hyaline membrane; Its flat turn cutter and sharp rotor are installed in the elongated slot of cutter shaft, have increased the firmness of tool setting; The horn shape cutting edge assembly mutually of the circular-arc cutting edge of its cutter of flatting turn and sharp rotor is thoroughly cut off hyaline membrane, has improved the reliability that cuts.

[description of drawings]

Further describe the specific embodiment of the present utility model below more in conjunction with the accompanying drawings.

Fig. 1 is the constructional drawing of the utility model background technology;

Fig. 2 is a constructional drawing of the present utility model;

Fig. 3 is the lateral plan of the utility model tool setting on cutter shaft.

[specific embodiment]

With reference to Fig. 2, Fig. 3, the film cutting apparatus of this three-dimensional packaging machine, has knife rest 1, cutter shaft and rotor, described cutter shaft is installed on the knife rest 1, described rotor is installed on the cutter shaft, described cutter shaft has first cutter shaft 2 and second cutter shaft 5, on first cutter shaft 2 and second cutter shaft 5, gear 6 is installed all, two gears are meshing with each other, so first cutter shaft 2 and the 5 relative rotations of second cutter shaft, gear 6 on first cutter shaft 2 or second cutter shaft 5 is by the driving system transmission of three-dimensional packaging machine, and described rotor has cutter of flatting turn 3 and sharp rotor 4, and the cutter 3 of flatting turn is installed on first cutter shaft 2, sharp rotor 4 is installed on second cutter shaft 5, described cutter 3 and the sharp rotor 4 of flatting turn is provided with on first cutter shaft 2 and second cutter shaft 5 vertically, and extends on the whole axial plane of first cutter shaft 2 and second cutter shaft 5, and described cutter 3 and the sharp rotor 4 of flatting turn is in contact with one another when cutting film; Described first cutter shaft 2 and second cutter shaft 5 are provided with elongated slot (not marking among the figure), and described cutter 3 and the sharp rotor 4 of flatting turn places this elongated slot respectively, and is fixed; The cutting edge of the described cutter 3 of flatting turn is circular-arc; The cutting edge cross section of described sharp rotor 4 is horn shape, and is reliably thorough when making it cut hyaline membrane with cutter 3 assembly mutually of flatting turn, and reduced noise.During the work of this device, hyaline membrane passes between first cutter shaft 2 and second cutter shaft 5, and hyaline membrane carries out film feeding by the another set of trailer coupling on the three-dimensional packaging machine; When the sharp rotor 4 on the flat turn cutter 3 and second cutter shaft 5 on first cutter shaft 2 is in contact with one another, just hyaline membrane can be cut off.
