When the cloth clamping and moving mechanism 3 drives the cloth to move, the lifting mechanism 502 drives the laser protection plate 503 and the upper air suction hard tube 504 to move downwards until the distance between the air suction opening 508 and the laser incision 101 is 1.2-1.6cm, and the air suction barrel 506 is opened; in the process of cutting cloth by laser, smoke can be generated and absorbed by the air suction barrel 506, the upper air suction hose 505 and the upper air suction hard tube 504, so that the smoke is prevented from diffusing and affecting the operation of an operator. The upper air suction hard pipe 504 is preferably made of a stainless steel pipe, so that the air suction and dust collection effects are achieved, the laser protection effect is achieved, meanwhile, the stainless steel pipe is convenient to obtain materials, mature in processing method, low in manufacturing cost and flexible in installation mode, and can be connected with other parts in modes such as welding. The top surface of laser protection plate 503 is equipped with transverse baffle 507, transverse baffle 507 is located go up the top of hard tube 504 that induced drafts, can further protect laser, prevent the skew of the hard tube 504 that induced drafts on leading to because of the accident, and make the laser take place the relative skew and go up the condition of inlet scoop 508 of the hard tube 504 that induced drafts, transverse baffle 507 plays the effect of secondary protection to laser, improves the utility model discloses a security.

Fixing base 501, elevating system 502, laser protection plate 503 and the outside of last hard tube 504 that induced drafts are equipped with air suction cover 509, it is right to go up air suction cover 509 when the laser cutting subassembly carries out the protection, form the third laser protection, improved greatly the utility model discloses operation process's security. When the cloth cutting is completed, the laser tube 403 stops emitting laser, the air suction barrel 506 is closed, and the lifting mechanism 502 drives the laser protection plate 503 and the upper air suction hard tube 504 to move upwards so that the air suction opening 508 of the upper air suction hard tube 504 is far away from the laser incision 101, so that the cloth can move conveniently; then, the cloth clamping and moving mechanism 3 drives the cloth to move away from the laser incision 101, and the whole laser cutting bag opening process is completed.

The bucket 506 of induced drafting and main control unit 6 itself are prior art, and its concrete structure does not do the perusal.

The utility model discloses a laser cutting unit mount has improved clothing notched precision in the below of operation panel 1 on the one hand, and on the other hand has practiced thrift installation space, makes the structure more reasonable and simplification simultaneously, and reduce cost lets the clothing enterprise more can and accept more easily. The upper air suction assembly of the utility model is mainly positioned at one side of the machine head 2, and meanwhile, the working area of the upper air suction assembly is not directly contacted with the operating platform 1, thereby facilitating the feeding, moving and cutting of cloth; the upper air suction assembly plays a role in laser protection while absorbing smoke generated in the cutting process, and three laser protections are formed by the upper air suction hard tube 504, the transverse baffle 507 of the laser protection plate 503 and the upper air suction cover 509, so that the health and safety of operators are guaranteed.
