A printing machine color group UV lamp curing mechanism

Abstract

This utility model discloses a UV lamp curing mechanism for a printing press, including a lamp housing, a light shield structure, a lamp tube, a light shield drive structure, and a connector structure. The lamp tube and the light shield drive structure are disposed in the lamp housing. The light shield structure includes a first light shield half-shield and a second light shield half-shield, which are rotatably disposed in the lamp housing, covering the lamp tube and forming a light outlet. The first light shield half-shield has a first cooling channel, and the second light shield half-shield has a second cooling channel. The light shield drive structure is driven to the first and second light shield half-shields, and drives the first and second light shield half-shields to rotate to open or close the light outlet. The connector structure is disposed at one end of the lamp housing and communicates with the first and second cooling channels respectively. Coolant is input from the connector structure. This utility model can improve the heat dissipation efficiency of the UV lamp, suppress high temperatures to promote the volatilization of harmful substances in the ink, and achieve the purpose of green environmental protection.
