[0036] like Figures 1-8 As shown, the principle of the double insurance glue machine paper break detection device provided in this embodiment is as follows: when using the device, the support fixing rod 8 should be welded and fixed in a designated place, and then the compressed air flow drainage pipe 4 is connected to the external compressed air tank. At this time, the photoelectric detection end 17 can be inserted into the installation slot 26.

[0037] When the device is operating, the double-insurance photoelectric detection structure 2 will detect the object to be detected, and transmit the detection results to the actual operation structure after processing. At the same time, the compressed air flow guide pipe 4 begins to quickly inject cold air into the disc exhaust pipe 5, and the cold air entering the disc exhaust pipe 5 will be quickly ejected from the air jet port 6, thereby quickly filling the entire photoelectric detection protective shell 1. At this time, the cold air filled in the entire photoelectric detection protective shell 1 begins to absorb the temperature of the various parts in the inner cavity of the photoelectric detection protective shell 1 and the external edge. Then the powerful fan 12 starts to rotate and quickly draws the air in the inner cavity of the photoelectric detection protective shell 1 to the outside, thereby forming a circulating convection of compressed cold air, which can achieve better heat dissipation effect, and thus make the device always in a suitable temperature state during operation.
