Abstract

The present invention provides a glass wool cutting device. The device includes a cutting section housing that has a cutting section chamber, a feed port that is connected to the cutting section chamber, and a discharge port that is connected to the cutting section chamber. A stationary knife is disposed on the cutting section housing to protrude into the cutting section chamber and a movable cutter that has a rotary support body is disposed in the cutting section chamber and a movable knife is supported on the rotary support body to apply a shearing force to the glass wool together with the stationary knife. Additionally, a cutter actuator provides a driving force to the rotary support body.

First claim

What is claimed is:

1. A glass wool cutting device, comprising:
a cutting section housing that includes a cutting section chamber, a feed port connected to the cutting section chamber to feed a glass wool into the cutting section chamber, and a discharge port having a size smaller than a size of the feed port and connected to the cutting section chamber to discharge the glass wool from the cutting section chamber;
a stationary knife fixedly disposed on an inner surface of the cutting section housing to protrude into the cutting section chamber;

a movable cutter having a rotary support body rotatably disposed in the cutting sect ion chamber and a movable knife supported on the rotary support body to apply a shearing force to the glass wool, which is fed into the cutting section chamber, together with the stationary knife and to cut the glass wool; and
a cutter actuator configured to provide a driving force to the rotary support body,
wherein the movable knife includes a movable knife body fixed to the rotary support body and a movable knife tip portion that extends from the movable knife body to be gradually decreased in thickness to form a movable knife blade along an end thereof for cutting the glass wool, and
wherein the movable knife blade and a stationary knife blade provided on the stationary knife for applying a shearing force to the glass wool together with the movable knife blade extend along a rotational central axis direction such that they are disposed in parallel to the rotational central axis of the rotary support body.

2. The glass wool cutting device of claim 1 , further comprising:
an air supplier connected to the cutting section housing to inject air into the cutting section chamber.

3. The glass wool cutting device of claim 1 , further comprising:
a glass wool compressing section configured to compress the glass wool into a panel form using a compression roller and supply the compressed glass wool to the feed port of the cutting section housing.

4. The glass wool cutting device of claim 3 , further comprising:
a feeding hopper connected to the cutting section housing to feed the glass wool into the cutting section chamber, wherein the feeding hopper includes a hopper feeding port in communication with the cutting sect ion chamber; and
a manual feeder having a hopper opening/closing part coupled to the feeding hopper to open and close the hopper feeding port.

5. The glass wool cutting device of claim 1 , further comprising:
a collection container having a collection section chamber, wherein the collection section chamber is in communication with the discharge port to allow the glass wool, which is cut in the cutting section chamber and discharged from the discharge port of the cutting section housing, to be accommodated therein;
a filtering sieve disposed on the collection section chamber to allow the glass wool with a size equal to or less than a predetermined size to pass there-through and then sort the glass wool; and
a vibrator connected to the filtering sieve to vibrate the filtering sieve.

6. The glass wool cutting device of claim 5 , wherein a plurality of filtering sieves are disposed on the collection section chamber, and a mesh net structure of an upper filtering sieve has a larger opening than a mesh net structure of a lower filtering sieve.

7. The glass wool cutting device of claim 1 ,
wherein the movable knife tip portion is arranged to be inclined with respect to a tangent line, which abuts an outer circumference of an imaginary circle centered on a rotational central axis of the rotary support body to allow the movable knife blade to be disposed at a front-most end of the rotary support body in a rotational direction.

8. The glass wool cutting device of claim 1 , further comprising:
a sub knife having a sub knife blade disposed in parallel to the stationary knife blade to apply a shearing force to the glass wool together with the stationary knife blade and to cut the glass wool,
wherein the sub knife protrudes from the movable knife towards the stationary knife to allow the sub knife blade to be positioned behind the movable knife blade in the rotational direct ion of the rotary support body.

9. The glass wool cutting device of claim 1 , further comprising:
a rotary knife having an imaginary circular arc shape formed at least a portion thereof and centered on the rotational central axis of the rotary support body to protrude from the rotary support body towards the stationary knife to cut the glass wool fed into the cutting section chamber.

10. A method for manufacturing a glass wool pellet, comprising:
feeding a glass wool into a cutting section housing that includes a cutting section chamber and a discharge port;
applying a shearing force to and cutting the glass wool fed into the cutting section chamber with a stationary knife, which is disposed and protrudes on an inner surface of the cutting section housing, and a movable knife white rotating the movable knife disposed in the cutting section chamber; and
sorting the glass wool having a size equal to or less than a predetermined size, which are cut and discharged from the discharge port, as a glass wool pellet,
wherein the movable knife includes a movable knife body fixed to the rotary support body and a movable knife tip portion that extends from the movable knife body to be gradually decreased in thickness to form a movable knife blade alone end thereof for cutting the glass wool, and
wherein the movable knife blade and a stationary knife blade provided on the stationary knife to apply a shearing force to the glass wool together with the movable knife blade extend along a rotational central axis direction such that they are disposed in parallel to the rotational central axis of the rotary support body.

11. The method for manufacturing a glass wool pellet of claim 10 , comprising compressing the glass wool into a panel form prior to feeding the glass wool into the cutting section, wherein the glass wool compressed into the panel form is fed into the cutting section housing.

12. The method for manufacturing a glass wool pellet of claim 10 , wherein the glass wool is cut while air is injected into the cutting section chamber by an air supplier connected to the cutting section housing.

13. The method for manufacturing a glass wool pellet of claim 10 , wherein a filtering sieve disposed below the cutting section housing is vibrated to allow the glass wool that has the size equal to or less than the predetermined size, discharged from the discharge port to pass through the filtering sieve and to be sorted as the glass wool pellet.

14. The method for manufacturing a glass wool pellet of claim 13 , wherein a plurality of filtering sieves are sequentially disposed below the cutting section housing, and a mesh net structure of an upper filtering sieve has a larger opening than a mesh net structure of a lower filtering sieve to sort the glass wool pellet.

15. The method for manufacturing a glass wool pellet of claim 10 ,
wherein the movable knife includes a movable knife body fixed to the rotary support body and a movable knife tip port ion that extends from the movable knife body to be gradually decreased in thickness and to form a movable knife blade at one end thereof, and
wherein the stationary knife includes a stationary knife blade disposed in parallel to a rotational central axis of the rotary support body, and the shearing force is applied to the glass wool with the movable knife blade and the stationary knife blade to cut the glass wool.

16. The method for manufacturing a glass
