The Acceptable life of long laser reduces period use cost.Fixed screw can keep laser will not during engraving
It is displaced, can effectively be fixed on crossbeam and be not easy to tilt.Ducted fan is mounted on laser by ducted fan fixing bracket
In engraving machine rack, misty of laser burns generation when can also work laser engraving machine while radiating to stepper motor
Grain is dispersed, and engraving precision is improved.
Laser radiator in the present invention is made of the aluminium alloy of perfect heat-dissipating, and mounting hole is arranged on radiator and pacifies
Dress is convenient, is not required to punch temporarily, time saving and energy saving, and unique round hole art chute designs can make laser head is upper in a certain range to lower
Section meets the engraving requirement to different size objects.Cooling fin, which is mounted on stepper motor objective table, can be effectively ensured laser
Stability when work.Stepper motor radiator in the present invention is radiated using 5V ducted fans, can be radiated to stepper motor
While effectively disperse light engraving machine work when laser burns generate mist particles.
The beneficial effects of the invention are as follows；
Heat-sinking capability of the present invention is strong, not easy to wear, extends the Acceptable life of laser, reduces period use cost,
It is easy for installation, it is not required to punch temporarily, the mist particles that laser burns generate when effectively dispersing the work of light engraving machine.
