Combined exhaust cooling system of laser cutting device

Abstract

The invention discloses a combined exhaust cooling system of a laser cutting device. The combined exhaust cooling system of the laser cutting device comprises an exhaust bucket. A laser tool head holder is arranged in the exhaust bucket, and a laser tool head is fixed on the laser tool head holder. An air tube plug is formed on an upper baffle plate of the exhaust bucket. One end of an air pipe duct is hermetically connected with the exhaust bucket through the air pipe plug. The other end of the air pipe duct extends outdoors. An optical fiber is connected with the laser tool head through the air pipe duct. Cold air is blown in towards the laser tool head to improve cooling effect, and a blow pipe is connected with the laser tool head through the air pipe duct. The combined exhaust cooling system has the advantages that flexibility of the optical fiber is effectively controlled through the air pipe duct, and properties of the optical fiber are protected; the air pipe duct is hermetically connected with the exhaust bucket, and exhaust flow from the exhaust bucket is discharged through the air pipe duct and cools the optical fiber.

Description

technical field [0001] The invention relates to a laser computerized embroidery machine, in particular to an exhaust cooling device of the laser computerized embroidery machine. Background technique [0002] When the laser cutting machine cuts materials, it will produce a large amount of toxic gas. If it is not handled properly, it will cause harm to the human respiratory system. [0003] Chinese patent ZL201120347320.6 discloses a computer laser embroidery machine, which includes a laser cutter head, an optical fiber for transmitting laser light, and a smoke exhaust pipe device. The optical fiber is connected to the laser cutter head, and laser cutting or embroidery is performed on the workbench. On the top cover of the embroidery machine (not shown in the figure), the smoke generated during cutting or embroidery by the laser cutter head cannot be directly discharged outside. [0004] More importantly, the optical fiber conduction line is long, and excessive bending of the...

[0002] When the laser cutting machine cuts materials, it will produce a large amount of toxic gas. If it is not handled properly, it will cause harm to the human respiratory system.

[0003] Chinese patent ZL201120347320.6 discloses a computer laser embroidery machine, which includes a laser cutter head, an optical fiber for transmitting laser light, and a smoke exhaust pipe device. The optical fiber is connected to the laser cutter head, and laser cutting or embroidery is performed on the workbench. On the top cover of the embroidery machine (not shown in the figure), the smoke generated by the laser cutter head cutting or embroidery cannot be directly discharged outside

[0004] More importantly, the optical fiber transmission line is long, and excessive bending of the optical fiber will degrade the performance of the optical fiber

At the same time, during long-term operation, the optical fiber generates a lot of heat during operation, which affects the service life of the optical fiber
