Safety protection interlocking device used during curling of coating product

The utility model relates to the technical field of coating product protection interlocking, in particular to a safety protection interlocking device for coating product curling, which comprises a U-shaped support, side vertical plates are detachably mounted on side walls, close to each other, of two side branches of the U-shaped support, and a plurality of sliding blocks are longitudinally arranged on the side vertical plates in a sliding manner. The multiple sliding blocks of one side vertical plate are provided with grating light emitters, the multiple sliding blocks of the other side vertical plate are provided with grating light receivers, and the grating light receivers can send out sensing signals for controlling linkage of the roll-dividing coating machine. According to the utility model, when an infrared beam in an infrared coverage area is shielded, a sensing signal in the grating light receiver can be sent out in time to stop the roll-dividing coating machine, so that a certain linkage exists betwe
