Abstract

The invention relates to a technique for the processing of polymeric materials and can be used in the rubber industrial industry. The purpose of the invention is to simplify the design and reduce energy consumption. The device comprises a disk knife 3 mounted on the drive shaft 1 with ribs 4 perpendicular to the plane of the knife and conical shells 5 mounted on these edges to the ends of the knife 3 with large bases. Conical shells 5 form axial clearances a with the ends of the knives, and with the drive shaft 1 - radial clearances b. During the rotation of the knife 3 ribs 4 suck air through the radial clearances b and throw it through the axial clearances a, cooling the edge of the knife. 2 Il.

gaskets, rubber mats and similar products.

The purpose of the invention is to simplify the design of the device for cutting non-metallic material and reduce energy consumption during its operation.

FIG. 1 shows a device for cutting non-metallic material; a general view; in fig. 2 is a section A-A in FIG. 1.

A device for cutting non-metallic tape material contains a disk knife 3 fixed to the drive shaft 1 by means of a nut 2 with ribs 4 perpendicular to the planes of the knife and conical shells 5 mounted on these edges with large bases to the ends of the knife with an axial clearance relative to the ends and with radial clearance b relative to the shaft.

The device works as follows.

The tape material (not shown) is fed to the cutting edge of the rotator.

from the disk knife 3 for cutting. When the knife rotates, the 3 ribs 4. Work as air wheel blades, sucking air through the radial clearances b and throwing it through the axial clearances a. Conical shells 5 provide the direction of air flow to the cutting edge of the disk knife 3. Several knives can be installed to one shaft.

Claims (1)

Invention Formula A device for cutting non-metallic material, comprising a drive shaft and a disk knife mounted on said shaft by means of a fixing unit, and means for cooling the knife, characterized in that, in order to simplify the design and reduce energy costs, the means for cooling the knife are made in the form of conical shells facing one to the other large bases located at both ends of the circular knife and rigidly connected with it by means of radially located edges, with the formation of axial and radial gaps between the top ost mi shell relative to said knife shaft and surfaces.
