Emission reduction assembly of printing equipment

The utility model discloses an emission reduction assembly of printing equipment, which comprises a conveying rack, a conveying belt, a driving device and a driving device, and the drying box is arranged above the conveying belt, and an infrared heating lamp is installed in the drying box. In the drying process, volatilized waste gas is sucked into the purification box body through the suction pump, then the waste gas is filtered through the built-in activated carbon layer, the waste gas is discharged into the drying box again after being filtered, and at the moment, the discharged and purified gas further carries heat, so that the drying efficiency of workpieces can be improved; exhausted gas is detected in real time through a gas concentration sensor, when the concentration of waste gas in the gas exceeds a set range, it is indicated that the activated carbon layer is saturated and needs to be replaced, at the moment, an audible and visual alarm gives an alarm to remind a worker to replace the activated car
