Description

Known designs of cutting machines for paper, photo paper (or similar materials) are either too large or too complicated and therefore too expensive. A design for both functions such as cutting and perforating is still

unknown.

The invention specified in claims 1 to 18 is based on the problem of creating a construction which enables two functions, or only one, in one device, is user-friendly and cost-effective to manufacture.

This problem is solved with the features listed in claims 1-15.

The invention makes it possible to cut and perforate easily and precisely with one device or just one of them and the special geometry of all parts means that they are very easy to shape and therefore cost-effective to produce.

An advantageous embodiment of the invention is specified in claim 2.

By adding 4 markings on the hood, which show the interface between the round tool and the flat material in both directions of movement. On one side of the hood (2 pieces) the vernier on the guide bar enables precise cutting or perforating. On the other side of the hood (2 pieces) it is possible to reach a specific spot on the material.

A further advantageous embodiment of the invention is specified in claim 3.

By using two springs, a slot was created between the main plate and the guide bar, which allows unhindered placement of the material on the set.

A further advantageous embodiment of the invention is specified in claim 4.

By using two sliders on the main plate it is achieved that;

a) the cutting group or the perforating group is movable on the guide bar along both sides

b) the cutting group or the perforating group when one of the sliders is moved to the other position, the mutual exchange

c) the guide rail retains its lateral locking in the main plate and its parallel position to the main plate.

A further advantageous embodiment of the invention is specified in claim 5.

By using a cutting insert which is loosely and symmetrically inserted into the main plate to offset the line of action of the tool, it is achieved that;

a) the cutter knife or the perforating knife does not become blunt

b) turning the cutting insert four times, which is an advantageous option

c) exchanging the cutting insert for a new system brings the advantage of b).

Description

A further advantageous embodiment of the invention is specified in claim 6.

The cross-section of the guide bar is matched to the cross-section of the cutter's hood (as well as the perforator), which ensures that it moves smoothly on the guide bar. The cross-section is not the same throughout, it is flattened at both ends, which allows both sliders on the main plate to function. In conjunction with the two springs and a slight pressure on the guide bar, towards the main plate, it fixes the material on the main plate.

A further advantageous embodiment of the invention is specified in claim 7.

Both groups, such as cutting and perforating, consist of the same parts, except for the cutter and the perforator, which enables cost-effective production.

A further advantageous embodiment of the invention is specified in claim 8.

Both parts, the cutting knife and the perforating knife, have the same basic geometry, except for the material cutouts in the perforating knife, which enables cost-effective production.

A further advantageous embodiment of the invention is specified in claim 9.

The diameter ratios of the large roller disc and the small roller disc are adjusted so that the small roller disc rolls on the guide bar and the large roller disc rolls on the material at the same time, which enables the material to be fixed and also ensures good quality of the cut or perforation.

A further advantageous embodiment of the invention is specified in claim 10.

The specially shaped rotation axis allows the cutting knife, the perforating knife, the small rolling disc and the large rolling disc to all rotate simultaneously in the cutting or perforating group.

A further advantageous embodiment of the invention is specified in claim 11.

Multiple tangential material cuts in the perforator enable the perforating function to be carried out. An angular, coaxial material cut in the perforator enables synchronous movement with other parts.

A further advantageous embodiment of the invention is specified in claim 12.

The specially shaped plug is pushed into the specially created groove in the housing, which allows a fixed placement of the rotary axis and guarantees that the associated parts do not fall out.

A further advantageous embodiment of the invention is specified in claim 13. The main plate is equipped with several details that enable

Description

by using four hemispherical knobs on the four slats, each of the two sliders can be moved and locked into one of two possible positions. The knobs on the shorter slats allow the two sliders to be installed easily for the first time, but also make it more difficult for them to accidentally move out of the main plate.

by using two cylindrical knobs in the two special recesses, one of the two springs is locked there and possibly permanently attached,

by using a specially shaped recess with two ribs, it is ensured that the cutting group or the perforating group is stored carefully before use,

by using a specially shaped recess, the storage of various small office supplies is possible,

by using several grooves in the main plate which provide both sliders with good guidance and prevent them from falling out of the main plate,

by using several vertical surfaces to the support surface of the plate, to create a stop, which enables right-angled machining,

By using several pieces of pipe on the underside of the main plate, several anti-slip inserts can be accommodated.

A further advantageous embodiment of the invention is specified in claim 14.

The wedge-shaped, double-installed limiter prevents the four slats from bending too far and thus from breaking off during the initial assembly, as well as when the two sliders are placed. However, this is purely a precautionary measure and does not affect the function.

A further advantageous embodiment of the invention is specified in claim 15.

The multiple anti-slip inserts prevent the set from slipping on the smooth surface of the workplace.

A further advantageous embodiment of the invention is specified in claim 16.

The interior of the hood forms a specially shaped frame, which allows easy storage of the rotation axis, lateral locking of both roller discs, as well as the use of the plug.

A further advantageous embodiment of the invention is specified in claim 17.

The hood has a continuous, adapted material cut on the guide bar, which enables a secure (no falling out possible) and unhindered movement of the two groups (cutting and perforating) on the guide bar.

A further advantageous embodiment of the invention is specified in claim 18.

The hood has a specially shaped external geometry adapted to the guide bar as well as to the main plate, which prevents injury in contact with the cutter or perforator.
