Method for burning and carving body surface of livestock and poultry with laser beam

Abstract

The invention relates to a method for burning and carving the body surfaces of livestock / poultry carcasses by use of laser beams. The method comprises the following steps that: burning-carving information is input into a laser equipment controller; livestock / poultry carcasses are kept still or put on a production line in motion; the body surfaces of the livestock / poultry carcasses face laser equipment; the inside of the laser equipment is provided with a laser, a vibrating mirror, a sensor, a beam expanding lens, an automatic zoom device and a focusing mirror; the laser equipment is controlled by the controller; the sensor outputs a signal to the controller after detecting that the livestock / poultry carcasses enter a laser marking area; the controller controls the laser to give off a laser beam; the laser beam is expanded by the beam expanding lens; the vibrating mirror is irradiated with the expanded laser beam before or after focusing; the controller controls the vibrating mirror to swing; the laser beam is focused on the body surfaces of the livestock / poultry carcasses through the swinging vibrating mirror and the focusing mirror so as to scan; and tracks form characters or graphs. The method has the advantages of leaving non-erasable marks on the body surfaces of the livestock / poultry carcasses, replacing the prior mode of marking the body surfaces of the livestock / poultry carcasses, preventing illegal livestock / poultry products from coming into the market and promoting the self-discipline of slaughtering enterprises.

Description

technical field

[0001] The invention relates to a method for burning with laser beams, in particular to a method for burning with laser beams on the body surface of livestock and poultry carcasses. Background technique

[0002] China is currently the world's largest producer and consumer of livestock and poultry meat, and the quality and safety of livestock and poultry meat is particularly important and urgent. In the four links of production, slaughter, circulation and consumption of livestock and poultry meat, there are different degrees of safety problems, such as private engraving of quarantine seals, forging of fake "Animal Quarantine Certificates", and more than one "ticket" of livestock and poultry meat In recent years, the phenomenon of illegal slaughtering in the livestock and poultry slaughtering industry, water-injected livestock and poultry meat, high-temperature livestock and poultry meat, and diseased and dead livestock and poultry meat flowing into the market ...
