Description

The utility model relates to equipment for cutting, mainly of roll materials, and can be used in the printing and other industries for cutting, for example, paper rolls.

Known device for cutting roll paper, containing a work table installed on the basis (RF patent No. 2 413 606, Mkl. B26D 1/46, B26D 3/16, publ. 03/10/2011).

The closest to the proposed technical solution is a device for cutting - a roll cutter of roll paper Steiger R 130, containing a work table mounted on a stand and a self-sharpening circular knife. (http://rezak.ru/steiger/r130.shtml).

A common disadvantage of these technical solutions is the fixed height of the desktop. This makes it difficult for operators of different heights and cleaning the premises at the end of the work.

The technical problem solved by the proposal is to improve the ease of use of the cutting device due to the possibility of adjusting the working height of the device and to facilitate cleaning of the room at the end of the work.

To solve this technical problem, a cutting device is proposed containing a working table, a self-sharpening circular knife, two parallelogram mechanisms, some links of which are attached to the sides of the working table, the opposite links of the parallelogram mechanisms are formed by fastening elements to the wall, at least one fastening element to the wall connected to an adjacent link of the parallelogram mechanism by a gas lift, the corresponding links of the parallelogram mechanisms can be rigidly connected.

The proposed cutting device can be manufactured on existing equipment from known materials and used in printing and other industries for cutting, for example, paper rolls. The applicant did not find other technical solutions for a similar purpose with a similar set of essential features during a search in scientific and technical literature and patent documentation. Therefore, the applicant considers that the proposal for this application meets the criteria for patentability of a utility model "novelty" and "industrial applicability".

The essence of the utility model is illustrated by drawings, which show a non-exclusive example of a cutting device.

FIG. 1 shows the cutting device in the maximally extended working position, FIG. 2, 3 - different positions of the working table

The figures indicate: working table 1, self-sharpening circular knife 2,, links 3, 4, 5, 6 of parallelogram mechanisms, which are attached to the sides of the working table 1, opposite links 5 and 3, 4 and 6 are connected to elements 7 of fastening to the wall , links 4, 6 of parallelogram mechanisms are connected by rigid connection 8, gas lift 9.

The device works as follows: parallelogram mechanisms, connected by a rigid link 8, provide adjustment of the height of the working table 1, keeping its horizontal position. Gaslift 9 ensures smooth operation of the device. If the gas lift 9 is made frictional, it provides fixation of the working table 1 at any intermediate height. When the working table 1 is maximally raised, the device (in plan) takes up a minimum of space.

The applicant has manufactured and successfully tested prototypes of the proposed cutting device.

Claims (3)

1. A device for cutting paper rolls containing a work table and self-sharpening circular knife, characterized in that it is equipped with fastening elements made with the possibility of fastening to the wall, two parallelogram mechanisms, some links of which are attached to the sides of the desktop, and opposite links are connected to the fastening elements to the wall, the corresponding links of the parallelogram mechanisms are rigidly connected communication to ensure adjustment of the height of the work table and maintain its horizontal position, while one of the fastening elements to the wall is connected to the adjacent link of the parallelogram mechanism by means of a gas lift. 2. The device according to claim 1, characterized in that the gas lift is made frictional.
