Abstract

The invention discloses a laser curing device for a rotary group type gravure printing machine, which comprises a frame, the lower part of the frame is provided with an overturning cylinder, one side of the frame is provided with a drive motor, the front part of the drive motor is provided with a drive shaft, and the drive shaft The front end of the flipper is installed in one end of the turning drum, and a first fixing seat is provided at an inner bottom of the frame, and a first positioning plate is provided on both sides of the upper part of one end of the first fixing seat, and a second positioning plate is arranged between the first positioning plates. A guide shaft, the first guide shaft is sleeved with a first sliding tube, the other end of the first fixed base is provided with a second positioning disc on both sides of the upper part, a second guide shaft is arranged between the second positioning discs, and the second guide shaft The outer peripheral surface of the roller is equipped with a second sliding tube, and the drive motor is installed on the second sliding tube and the first sliding tube; the outer peripheral surface of the turning drum is provided with a number of laser curing lamps and UV point light source curing lamps. The invention facilitates the flexible horizontal rotation adjustment of the turning drum, so that the horizontal movement adjustment of the laser curing lamp and the UV point light source curing lamp can be conveniently carried out.

Description

technical field [0001] The invention relates to a laser curing device, in particular to a laser curing device for a rotary gravure printing machine. Background technique [0002] Photocuring refers to the curing process of monomer, oligomer or polymer matrix under light induction, and is generally used in the film forming process. Photocuring of unsaturated polyester resin; the activation energy generated by ultraviolet light with the highest energy in the spectrum can break the C—C bond of unsaturated polyester resin and generate free radicals to cure the resin. When a photosensitizer is added to the unsaturated polyester resin, ultraviolet light or visible light is used as the energy source to initiate the crosslinking reaction of the resin. Photocuring technology is a kind of optical processing technology that makes liquid epoxy acrylic resin polymerize into a solid state at a high speed through the irradiation of ultraviolet light of a certain wavelength. The photocurin...
