Protection cover for protecting laser marking machine and laser marking machine cabinet

Abstract

The invention discloses a protection cover for protecting a laser marking machine, comprising a turret inner sleeve, a turret outer sleeve and a stepping motor. The turret outer sleeve covers the outside of the turret inner sleeve, and the turret outer sleeve and the turret inner sleeve are connected through a central shaft. The stepping motor is arranged in the protection cover and drives the turret outer sleeve to rotate or drives the turret inner sleeve to rotate. When laser marking is needed, the stepping motor drives the turret outer sleeve to rotate or drives the turret inner sleeve to rotate around the central shaft to ensure that the laser light emergent holes of the turret outer sleeve and the turret inner sleeve are overlapped and aim to a marking object. When cleaning is needed, the stepping motor drives the turret outer sleeve to rotate or drives the turret inner sleeve to rotate around the central shaft to ensure that the laser light emergent hole of the turret inner sleeve is shielded by the outer wall of the turret outer sleeve. In the invention, the laser marking machine can be very conveniently transformed between the working state and the cleaning state, and during cleaning, cleaning solution can not splash to the laser so that the laser is well protected.

Description

Technical field [0001] The invention relates to the technical field of laser marking, in particular to a protective cover for protecting a laser marking machine and a laser marking cabinet using the protective cover. Background technique [0002] At present, China is the world's largest producer and consumer of livestock and poultry meat. The quality and safety of livestock and poultry meat is particularly important and urgent. In the four links of livestock and poultry meat production, slaughter, circulation, and consumption, there are different degrees of safety problems, such as privately engraved quarantine seals, forged "Animal Quarantine Certificates", and more livestock and poultry meat Wait for the situation. [0003] At present, stamping is mainly used to mark the surface of the carcass of livestock and poultry after slaughter. This method is not beautiful, pollutes the carcass of livestock and poultry seriously, and affects the circulation of products. Moreover, the sta...

The entire system forms a closed-loop control, and counterfeiters cannot implement batch counterfeiting

[0005] However, because laser marking on the surface of livestock and poultry needs to be carried out at the slaughter site of livestock and poultry meat, in order to control from the source of circulation, and the environment of the slaughter site is very harsh (often need to wash with water), and based on food safety, the slaughter The on-site environment has relatively strict requirements. Therefore, the existing laser marking machine cannot be directly applied to the slaughter site and needs to be improved.
