Felt cloth laser cutting machine

Abstract

The invention relates to the technical field of laser cutting, and discloses a felt cloth laser cutting machine. The machine comprises a rack, a transverse cross beam is fixedly installed above the rack, a laser generator is fixedly installed at one side of the cross beam, and plate columns located below the cross beam are fixedly installed at the two sides of the upper surface of the rack. Screenplates movably sleeve the outer portions of the plate columns in a sleeving manner, screen plate springs fixedly sleeving the outer sides of the plate columns are fixedly installed on the upper surfaces of the screen plates, and large resistors located below the screen plates are fixedly installed below the plate columns. According to the felt cloth laser cutting machine, the thickness of the machine is distinguished through the weight of felt cloth, meanwhile, the larger a magnetic field generated by an iron core is, the farther an annular magnet moves downwards through the downward moving distance of the screen plates, and then a convex lens is closer to the surface of the felt cloth, the distance between a nozzle and the felt cloth is not changed; and the nozzle part is not easily influenced by the cutting temperature, and the service life of the nozzle is prolonged.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a felt cloth laser cutting machine. Background technique [0002] Felt cloth laser cutting machine is a new type of cutting equipment used to cut or describe felt cloth. Due to the soft and easy-to-deform characteristics of felt cloth, in the previous felt cloth cutting, when the cutting knife is pressed on the felt cloth for cutting , The tool needs to press the felt cloth first and then cut it, so the cut product often has an uneven cutting surface, so now there is a laser cutting machine to cut the felt cloth. [0003] However, there are some problems in the cutting process of the felt cloth laser cutting machine: First, because the thickness of each felt cloth is not the same, it is necessary to move the laser head down during the cutting process of thicker felt cloth so that it can cut To the bottom layer of the felt cloth, but the laser head moves downward, making th...

[0002] Felt cloth laser cutting machine is a new type of cutting equipment used to cut or describe felt cloth. Due to the soft and easy-to-deform characteristics of felt cloth, in the past felt cloth cutting, when the cutting knife is pressed on the felt cloth for cutting , the tool needs to press the felt cloth first and then cut it. In this way, the cut product often has an uneven cutting surface, so now there is a laser cutting machine to cut the felt cloth.

[0003] But there are some problems in the cutting process of the felt cloth laser cutting machine: First, because the thickness of each piece of felt cloth is not the same, it is necessary to move the laser head down during the cutting process of thicker felt cloth in order to be able to cut To the bottom layer of the felt cloth, but the laser head moves downward, making the distance between the laser head and the felt cloth closer and closer, while the laser cutting machine uses the heat energy generated by the laser to cut, and the closer the distance, the higher the heating temperature of the laser head. Eventually, the laser head is burned out, which reduces the service life of the laser head; secondly, because the laser shoots out to form a path, the upper layer of felt cloth is always in a heated state when the laser cuts from the upper layer of the felt cloth to the lower layer, and the The felt cloth is greatly affected by heat, so that after cutting, the edge of the cut product is V-shaped, which makes the cutting accuracy of the product not high
