Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a zoned dust removal mechanism for laser cutting machines. Background Technology

[0002] When a laser cutting machine is working, it needs to blow away the powder particles generated during cutting through the air damper. However, the existing air damper cannot perform dust removal synchronously with the cutting process, resulting in poor dust removal effect. Summary of the Invention

[0003] In order to overcome the technical defects of the existing technology, this utility model provides a zoned dust removal mechanism for a laser cutting machine.

[0004] The technical solution adopted in this utility model is: a zoned dust removal mechanism for a laser cutting machine, including a laser cutting machine bracket. The side plate of the laser cutting machine bracket is provided with a plurality of air vents along the working direction of the cutting machine. Each air vent is provided with an air outlet. A dust cover is provided inside the air vent. A driving device is also connected to the dust cover. The driving device drives the dust cover to move horizontally. The dust cover includes a closed dust-proof position that fits with the air outlet and an open dust-blowing position that is separated from the air outlet.

[0005] Each of the aforementioned damper cavities, located along the working direction of the cutting machine, is independently controlled to open and close via an independent dust cover and drive device.

[0006] An isolation net is also provided on the air outlet.

[0007] The isolation net is provided with positioning holes, and the dust cover is provided with positioning blocks. When the dust cover is attached to the air outlet, the positioning blocks and positioning holes are in a limiting fit.

[0008] The isolation net and the damper cavity are connected by a guide rail, and the dust cover is provided with a slot that matches the guide rail. The dust cover is guided and engaged with the guide rail through the slot.

[0009] The damper cavity also includes a back plate, and the drive device is mounted on the back plate.

[0010] The bottom of the laser cutting machine bracket is also provided with a first support foot and a second support foot to support the laser cutting machine bracket. The first support foot is located at both ends of the bottom of the laser cutting machine bracket, and the second support foot is located in the middle of the bottom of the laser cutting machine bracket.

[0011] The driving device is a cylinder.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a zoned dust removal mechanism for a laser cutting machine, including a laser cutting machine support. Several air vents are provided on the side plate of the laser cutting machine support along the working direction of the cutting machine. Each air vent has an air outlet, and a dust cover is provided inside the air vent. A driving device is also connected to the dust cover, which drives the dust cover to move horizontally. The dust cover includes a closed dust-proof position that fits against the air outlet and an open dust-blowing position that separates from the air outlet. During dust removal, each independent driving device controls the air vent at the working position of the cutting beam to open for dust removal. When the cutting beam cannot move to the next position, the original air vent closes to prevent dust particles from entering the air vent during dust removal. The air vent at the position reached by the cutting beam opens for subsequent dust removal. Attached Figure Description
