The drying speed of the printing ink is reasonably controlled, the physical and chemical mechanism in the printing ink drying is mastered, the rapid printing operation can be effectively carried out, and the product quality is ensured. Too fast drying of the ink can reduce the normal transfer performance of the ink and influence the normal operation of production; the ink is weakened and pale in color, and the surfaces of the printing plate and the ink roller are dry and hard, so that the ink feeding in the transmission is blocked; expanding the image-text dry layer of the printing plate outwards; the phenomenon that the ink adsorbability is increased and the blank part is dirty and the like is caused by the overlarge consumption of the drying agent. The printing ink is dried too slowly, so that overprinting difficulty, adhesion and the like can be caused, and the firmness is reduced; scratch and the like are easily caused in the conveying process. Therefore, the drying speed of the ink is suitable, and too fast and too slow are not favorable. Therefore, the ink is dried by the curing machine.

Detailed Description

The technical scheme and the beneficial effects of the utility model are clearer and clearer by further describing the specific embodiment of the utility model with the accompanying drawings of the specification.

Referring to fig. 1 and 2, the UV drying apparatus of the present embodiment includes: control platform, feeding zone, printing drying zone, cooling zone, receipts material district. The control platform is respectively connected with a feeding area, a printing and drying area, a cooling area and a material receiving area which are sequentially sequenced, the printing and drying area is provided with a printing machine which is positioned at the downstream of the feeding area and used for coating ink on the easy-open cover sheet, and a UV-LED curing machine which is positioned at the downstream of the printing machine, a UV-LED lamp is arranged on the UV-LED curing machine, and a plurality of ultraviolet light-emitting diodes are arranged on the UV-LED lamp. The UV-LED irradiates and solidifies the ink by utilizing UV-LED light, which is one of LEDs and is invisible light with single wavelength, and can emit a complete continuous ultraviolet band, thereby meeting the fixed production requirement after ink printing. The high-power light-emitting diode does not emit infrared rays, the linear light source has an ultra-long service life, is a cold light source, does not have heat radiation, is not influenced by the switching frequency, has high energy, uniformly irradiates and improves the production efficiency, and does not contain toxic substances, so that the high-power light-emitting diode is safer and more environment-friendly than the traditional light source. The temperature of the surface of the irradiated product rises to below 5 ℃, but the ultraviolet curing machine in the traditional mercury lamp mode generally raises the surface of the irradiated product by 60-90 ℃, so that the positioning of the product is displaced, and the product is poor. Therefore, the LED type curing machine adopts semiconductor light emission, has no factor of polluting the environment and is more environment-friendly; meanwhile, the UV-LED mode of the UV-LED curing machine only consumes power during irradiation, and the power consumption is almost zero during standby, so that the effective luminous efficiency is more than 10 times higher than that of a mercury lamp mode.

Wherein at least one printing drying area is provided, and each printing drying area is provided with at least one printing machine and at least one UV-LED curing machine. Compared with the mercury lamp service life of the traditional UV curing equipment which is only 800-3000 hours, the UV-LED curing machine adopts a UV-LED ultraviolet curing system, and the service life of the UV-LED ultraviolet curing system reaches 20000 hours. The LED system may be turned on instantly only when ultraviolet light is required, and the service life of the LED system is 30 to 40 times that of the mercury lamp system when the duty is 1/5 (the preparation time is 5 and the irradiation time is 1). The time for replacing the bulb is reduced, the production efficiency is improved, and meanwhile, the energy is saved. When the traditional mercury lamp mode curing equipment works, the mercury lamp is started slowly, is opened and closed to influence the service life of a bulb and must be always lighted, so that unnecessary power consumption is caused, and the service life of the mercury lamp is shortened.

Because each UV-LED curing machine is provided with a plurality of ultraviolet light-emitting diodes which independently emit light, each irradiation head independently emits light through LED type irradiation, and the irradiation energy is not influenced by the increase of irradiation channels and is always kept at the maximum value. Compared with a mercury lamp, the LED type irradiation head of the UV lamp has ultra-strong concentrated illuminance, the irradiation time of operation is effectively shortened, and the production efficiency is improved. Therefore, the problem that when the irradiation channels are increased in a traditional mercury lamp point light source curing machine, the output energy of each irradiation channel is reduced due to the increase of the channels is solved.

As shown in fig. 1, the present embodiment is provided with two printing dry zones, each of which is provided with one printing press and one UV-LED curing machine. The first printing and drying area is in butt joint with the feeding area, and two UV-LED lamps are arranged on a UV-LED curing machine of the first printing and drying area and used for carrying out first printing and first curing on the sheet; the second printing and drying area is arranged between the first printing and drying area and the cooling area, and four UV-LED lamps are arranged on a UV-LED curing machine of the second printing and drying area and used for carrying out second printing and second curing on the sheet. During each curing, the UV-LED curing machine adopts a high-power LED chip and a special optical design, so that the ultraviolet light can reach high-precision and high-intensity irradiation. By adopting the latest optical technology and manufacturing process, the high-intensity output and uniformity which are more optimized than those of the traditional mercury lamp irradiation mode are realized, and the irradiation intensity is almost 2 times that of the traditional mercury lamp irradiation mode, so that the UV adhesive is cured more quickly, the production time is shortened, and the production efficiency is greatly improved.

It can be understood that in other embodiments, the specific number of the printing drying zones is set according to different printing requirements and curing requirements, so that multiple operations of printing and curing are realized, and the high-quality printing effect of the ink is ensured.

As shown in fig. 2, the UV-LED curing machine is also disposed between the feeding machine and the printing machine, and the UV-LED curing machine disposed between the feeding machine and the printing machine can be used for sterilizing the sheets input by the feeding machine by light irradiation, so as to improve the quality of subsequent printing.

As shown in fig. 1 and 2, a printing sampling inspection table is arranged between the printing machine and the UV-LED curing machine, and is used for sampling and detecting the effect of the printed sheet to prevent subsequent ineffective curing operation.

As shown in figures 1 and 2, a quality sampling inspection table is arranged between the cooling area and the material receiving area and used for sampling and detecting the printed and cured sheet, and whether the printed or cured sheet has printing or curing defects or not is guaranteed.

As shown in fig. 1 and 2, in the present embodiment, the feeding zone is provided with a feeder connected to the printing and drying zone, and the feeder is provided with a feeding roller table for conveying the easy-open lid sheet. The material receiving area is provided with a material receiving machine which is butted with the printing and drying area, and the material receiving machine is provided with a discharging roller way for outputting the easy-open cover sheet material which finishes the printing ink printing.
