Description

Fire prevention device for curing lamp Technical Field The utility model belongs to the technical field of drying and curing of printing machines, and particularly relates to a fire prevention device of a curing lamp. Background At present, after a coil stock printer (such as a gravure press, a flexo press, a coil stock digital printer and the like) performs ink-jet printing on paper, the paper needs to be dried and cured by a curing lamp, but when an abnormal condition that a machine suddenly stops occurs, the curing lamp irradiates the same position of the paper for a long time, and because the working temperature of the curing lamp is higher, even if the curing lamp is turned off, the waste heat of the curing lamp can possibly cause the paper or other inflammable forage at the irradiation position to be high Wen Kaojiao or even fire, thereby causing production safety accidents. Therefore, how to avoid the heat of the curing lamp to cause the paper to fire up Wen Kaojiao is a problem to be solved by those skilled in the art and urgent need in the abnormal situation that the paper stops being transported. Disclosure of utility model The utility model aims to solve the technical problems of overcoming the defects of the prior art and providing a fire prevention device of a curing lamp, which comprises a shutter baffle, an optical axis and a driving part; The two ends of the optical axis are respectively provided with a first mounting piece and a second mounting piece, and the optical axis is suitable for being mounted at a position to be mounted through the first mounting piece and the second mounting piece; One side of the shutter baffle is connected with the optical axis through a connecting component, and the shutter baffle is suitable for being arranged at the side of the curing lamp through the optical axis; The driving part is in driving connection with the optical axis and is suitable for driving the optical axis to move along the length direction of the optical axis so that the optical axis can drive the shutter baffle to move to the position between the curing lamp and the paper for heat insulation.
