Problems solved by technology
The current printing method lacks effective means to remove organic solvents. After the printed matter is discharged, a large amount of organic solvent vapor directly volatilizes into the air in the workshop, which is likely to cause occupational diseases in the workshop personnel. Special printed materials such as certificates and lottery tickets urgently need new post-press treatment. Way

Embodiment Construction
[0032] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0033] The strip-shaped intermediate finished product 50 of printed matter in the present invention generally refers to certificates, lottery tickets, etc., which have only been printed with ink but have not yet dried and solidified. Since they have not been cut and separated, they are generally strip-shaped and need to be irradiated. The UV light dries and cures the ink. However, the current equipment functions are too old, and there are only post-light curing measures, and the energy efficiency is not high. Moreover, the strip-shaped printed intermediate product 50 after the light curing is completed is directly discharged, and a large amount of orga...

The invention discloses a photo-cured printing ink printed matter printing post-treatment device. The hardware of the device comprises a machine frame, a photo-curing irradiation module, a blowing module, an air extracting module, a rotating-in roller and a rotating-out rotating roller, wherein a shell is arranged on the machine frame, a channel is arranged in the middle of the shell and comprisesa feeding end and a discharging end, the channel is used for allowing a belt-shaped printing object middle finished product to pass through, and the shell internally comprises a photo-curing chamberand a volatilization chamber; the photo-curing irradiation module is used for projecting the belt-shaped printing object middle finished product; the blowing module is provided with an airflow slow-release structure; the air extracting module is used for separating steam volatilized from an organic solution; the rotating-in roller is movably arranged on the outer side of the feeding end; the rotating-out rotating roller is movably arranged on the outer side of the discharging end; and the rotating-in roller and the rotating-out rotating roller are both used for lifting the belt-shaped printedobject middle finished product. The device is used for taking measures that the organic solvent can be promoted to volatilize after the photo-curing process of the special printed matter is met, and the solvent steam can be discharged in time.
Description
technical field [0001] The invention relates to the field of processing technology for intermediate products in the anti-counterfeiting printing industry, in particular to a device for post-printing of photocurable ink printed matter. Background technique [0002] Existing special printed matter such as certificates, lottery tickets, etc., will be printed with light-curable ink. Specifically, printed matter that has just been printed with light-curable ink will generally be printed in an environment exposed to ultraviolet light, so that it will dry as soon as possible. Specifically, due to Printed materials such as certificates and lottery tickets will be strip-shaped intermediate products before cutting, so they will pass through the rollers to affect the non-printed side of the strip-shaped intermediate products, and then turn the printed side to the ultraviolet light source. However, due to the unreasonable arrangement of the ultraviolet light emitting device in the exist...
