SU39917A1 - Machine for cutting rubber belts with fabric pads, rubber plates, etc. - Google Patents

Description

Machines for cutting belts made of rubber, leather, etc., are already known, consisting of a series of flat knives mounted inclined to the plane of the material being cut in such a way that the knives are produced immediately: across the entire thickness of the material.

In the present proposal, in order to change the inclination of the knives, the latter are fixed in the holders, positioned in an adjustable manner on the ocri and controlled by a sling stalk coupled to the gear mounted on the flywheel.

In order to direct the material to be cut at the places where the knives are located in the machine, special plates are used, which are also fixed in a adjustable way.

The drawing shows schematically an exemplary embodiment of the proposed machine.

On the axis 1 lying across the machine, in the bearings 2 there are reinforced plates 3, which support the material being cut from below 4. At the ends of axis 1, the downward straight line guides for gear racks 5 are fastened. At the upper ends of the rails 5 there are ravines through which the axis passes 6 carrying

(79;

; 1 stalls with knives fastened in them 7. The holders can be rearranged along the axis, with a t-minute change in the width of the belts being cut or the floor (to. On the axis 1, apart from the plates 3. there are brackets 8 fitted with linear guides 9 for brackets 10 carrying an axle 11 on which plates 12 are put on, guiding the material being cut. iapr; that are for the cut The plate, plates 12, 3 are provided with slots for the knife 7. The material to be cut 4 is fed straight to the knife blade using any suitable device, for example, the feed rolls 16. In the place where the blades 7 are located, the material passes between tangles for different materials can be changed both for each knife separately and for all at the same time, as holders with knives can be rotated and secured

in any position on the axis lying in the bearings of the rails 5, and the guides for the rails can likewise on the axis 1. In this case, the inclination of the plates 12, 3 can also be changed accordingly, since the plates 3 can rotate around the axis 1 and fasten on it in the desired position as well as the brackets 8, the carrier plates 12. feaS r The machine’s action is that the material being cut 4 is fed to the knives 7 between the guide plates 12 and 3. The blades are cut into belts with a width equal to distance between yozhami, and then retracted from for d no processing.

The subject matter of the invention.

Claims (2)

1. A machine for cutting rubber straps with fabric pads, rubber plates, etc. using flat knives mounted inclined to the plane of the material being cut, characterized in that with the purpose of changing the inclination of the knives the knives 7 are fixed in holders located unreplicable on axis 1 and controlled by a sponge stick 5 coupled to a gear mounted on the flywheel 15. 2. In the machine tool according to claim 1. use rotary and permuted relative to the axis 1 of the plates 12, 3, which serve for the wiring between the material being cut at the locations of the knives.
