Description

The proposed tissue cutting device is one of the machines of this kind, in which a knife is used, driven from the motor in a reciprocating motion. The latter is achieved with the help of a gear system and a crank or eccentric mechanism, with the ability to set and fix the position of the knife at various desired heights. For ease of movement and installation of the entire fixture along the material being filled in, there is a rock lifting device. In FIG. 1 shows lateral adaptation; FIG. 2-hinge gook in the drive from the motor to the knife. Plate 1, on which all the delays are collected, serves as the base of the machine and can be moved on the rollers 2 in various etches along the material to be 4k. The rollers can be lifted by the position of the levers 6 coupled to the pole and 4 and 5 with the handles 3. These rollers, which can be produced by the anthem, are needed to give the whole machine a stable VHHC for those moments when it is in shape. For the denser with and / and the plate 1, the outsole is supplied with rubber glue 7 to the material being laid down. with eccentric or. with crank 12 on the shaft 18, driven by the motor 13, either by means of a system of gears 14, 15, 16, 17, or by means of a Hook hinge (Fig. 2). The shaft 18 is resting in sliding bearings 20, which can be raised or lowered by means of a toothed rack 21 connected to them, driven by a gear 22 with a handle 23. On the handle 23 there is a cutting rod 24, pressed by a spring 25, which rod It serves as a brake for the wheel 22. The rod 24 falls into the gaps between the teeth of the stationary gear wheel 26 and thereby fixes one or another position of the shaft 18, the eccentric or the shaft 12, and at the same time the position of the slide 10 and the knife 27 fixed in it ). When replacing the gears 14, 15,16,17 by Hooke's articulated clutch, the rod 28 of the latter is made expandable (telescopic tubes on the key), so that you can move the shaft 18 more within great limits. and the other end of the 30-shaft motor. For a more uniform rotation of the shaft 18, a flywheel 31 is associated with it.

The subject of the patent.

L A device for cutting tissue using a crank and gear drive driven by a motor in reciprocating motion.

a knife, characterized in that the axis of the gear wheel 17 is arranged immovable in the latter on a key for mounting, using a pinion gear 21 and 22, a knife and informing it of the movement of the mechanism at a desired height above the cut tissue.

2. The form of execution of the device according to claim 1, characterized in that it is used to facilitate the movement of the device, roles 1 and 2-2, for switching off which are gears 4 and 5.

3. In the device according to p. 1 and 2 are used in the drive mechanism from the motor to the Hooke's hinge knife.
