Description

DEVICE FOR SEPARATION OF SHEET PAPER MATERIAL

The useful model refers to devices for the printing industry.

A device for cutting sheet of paper material (and.SSSSR No. 1423377, class. 26 D 1 | 20.1987), containing a table for the material, a drive knife mounted with the possibility of reciprocating movement, the beam of the clamp sheet material, placed on one side of the cutting plane. It is intended primarily for cutting a stack of paper material. High-quality pressing of the last sheets with a knife is carried out by a pneumatic device.

Closest to the proposed technical solution is a device for separation - cutting of sheet paper material in the form of a single-knife paper-cutting machine (AS USSR J 2342757, class B 26 D

at 26 D 1/06 1/06, 1968). It contains the base in the form of a table with a rigidly fixed

on it with a knife holder, a sheet paper feeder in the form of a carriage on rolling bearings, which moves in a direction perpendicular to the line of movement of the knife, with a flat substrate for sheet paper material. This device is intended for cutting sheets of paper, but cannot provide for the separation of paper material of various thicknesses into parts by other methods, for example, delamination using notches.

The technical result of the proposed technical solution is to expand the functionality of the device by ensuring the separation of paper material not only by cutting it, but also by delamination, which allows us to expand the range of processed paper materials.

It is achieved by the fact that the device for separating sheet paper material containing a base, a knife holder fixed thereon, located on the base with the possibility of plane-parallel movement of the carriage with a flat substrate for sheets of paper material, further comprises a two-stage insert with the possibility of alternately placing each of its steps into the carriage next to the substrate, and the knife holder is equipped with a mechanism for fixing the knife edge at a different distance from the plane of the substrate.

In fig. Figure 1 shows a general view of the utility model, and Fig. 2 two-stage insert.

The proposed device comprises a base 1 with a holder 2 for knife 3 fixed on it, which has a locking mechanism 4 of the knife edge 3 at different distances from sheet paper material. On the base 1 there is a carriage 5, on which a flat substrate 6 for sheets of paper material and a two-stage insert 7 are placed. The carriage 5 can, using the guides 8, perform plane-parallel movement along the base 1.

The device operates as follows.

A sheet of paper material is laid on a flat substrate 6 of the carriage 5, and it is brought to the knife 3 until its tip contacts the material. Next, establish the necessary depth of immersion in the material, which depends on the functional purpose of this operation.

If it is necessary to make a cut of paper, a certain immersion depth is set, and the operation is carried out once. For this, the substrate 6 together with the carriage 5 are manually moved in the direction of action of the knife tip.

if it is necessary to prepare paper material for dividing it into parts by layering, for example, in the manufacture of business cards, carry out the following. First, set the required immersion depth of the tip of the knife 3 in the material. Then, the substrate 6 and the insert 7 mounted on the carriage 5 are moved in the direction of the tip of the knife 3, thereby delaminating the paper material. Then repeat this operation, turning the liner 7. Moreover, observe the distance between the notch lines - this value is approximately 0.3 mm. It is due to the properties of the paper material. The transverse distance between the steps of the liner 7 determines the distance between the notch lines.

The proposed design of the utility model can be widely used for working with such paper materials, the separation of parts of which by separation must be carried out as needed. It can be, for example, business cards. The business cards that passed the processing described above with two lines that ensure the separation of the material are folded together and fastened into a single set. As necessary, business cards are torn off from the bonded spine at the place of material separation.
