Fiberglass cloth cutting device

Abstract

This invention proposes a fiberglass cloth cutting device for cutting a fiberglass cloth, comprising an inlet end, an outlet end, and a cutting assembly. The cutting assembly is disposed between the inlet and outlet ends and includes a blade assembly and a laser emitter assembly. The laser emitter assembly has two laser emitters arranged side-by-side along the direction of movement of the fiberglass cloth, emitting laser light towards the fiberglass cloth and forming a laser path. The blade assembly cuts the fiberglass cloth along the laser path. When one laser emitter emits laser light onto the surface of the fiberglass cloth and heats it, the other laser emitter is turned off for cooling to prevent overheating. Furthermore, when switching between the two laser emitters, both emit laser light towards the fiberglass cloth simultaneously.

Claims

1. A fiberglass cloth cutting device for cutting a fiberglass cloth; the fiberglass cloth cutting device comprising: a feed end through which the fiberglass cloth can enter the fiberglass cloth cutting device; a discharge end through which the fiberglass cloth can leave the fiberglass cloth cutting device; a cutting assembly disposed between the feed end and the discharge end; the fiberglass cloth being movable through the cutting assembly; the cutting assembly comprising: a blade assembly disposed between the feed end and the discharge end for cutting the fiberglass cloth; a laser emitter assembly disposed between the blade assembly and the feed end, the laser emitter assembly for emitting laser light toward the fiberglass cloth and forming a laser path on the fiberglass cloth; the laser emitter assembly comprising: Two laser emitters are arranged side-by-side along the direction of movement of the fiberglass cloth; each laser emitter emits laser light towards the fiberglass cloth, forming a laser path on the fiberglass cloth; wherein... When one of the laser emitters emits a laser toward the fiberglass cloth, the other laser emitter may emit a laser toward the fiberglass cloth or not.

2. The fiberglass cloth cutting apparatus as described in claim 1, wherein, The laser emitters emit lasers in a direction perpendicular to the direction of movement of the fiberglass cloth.

3. The fiberglass cloth cutting apparatus as described in claim 1 or 2, wherein, The blade assembly comprises: two circular blades located above and below the fiberglass cloth, respectively; each circular blade has a pivot and two side surfaces, and each circular blade can rotate about its pivot; the distance between the two pivots is less than or equal to the sum of the radii of the two circular blades; a portion of one side surface of each circular blade abuts against each other, and the abutting portion is aligned with the laser path.
