This is a sign laser marking machine, mainly composed of a laser marking component, a sign discharging component, a sign blanking component, and a smoke treatment component. The height of the laser marking head can be adjusted by manually shaking the trapezoidal screw rod. The incoming signs are in a stack and are placed in the silo of the sign discharging mechanism. The silo is equipped with a counterweight block, which can be used to adapt to signs with a relatively light weight (the counterweight block can be removed if the signs are heavy enough). The device has a built-in smoke pipeline, and an external smoke purifier can be connected through the top of the outer cover. This is an SW source file, which can be freely edited. The structural details of the whole machine in the file are well-perfected. I hope you will like it.
