Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an online heating and hot stamping composite device. Background Art

[0002] Among the existing patents, the Chinese patent document with application number 202311755431.4 discloses a digital printing machine with flexographic printing and hot stamping composite integration, including: a main unwinding assembly, on which several layers of substrate are sleeved; a flexographic printing assembly, used to evenly print ink patterns on the surface of the substrate; a hot stamping film assembly, used to cover the hot stamping film on the printed pattern of the substrate; a frame, on which the main unwinding assembly, the flexographic printing assembly, and the hot stamping film assembly are sequentially arranged. The present invention combines traditional flexographic printing technology with digital printing technology to enrich the functions of the digital printing machine; a flexographic printing seat is arranged in front of the digital printing, which can be used for the varnishing process, and the digital printing effect is better; the hot stamping film assembly is arranged after the flexographic printing assembly, and the hot stamping film composite integrated production process has a more concentrated processing technology that saves time and simplifies equipment integration; it is compatible with the coating process and the hot stamping process, and can be hot stamped first and then digitally printed according to the special needs of customers. However, the patent document states that after the substrate is UV-cured, the temperature of the substrate will rise without immediate cooling, so that the tension of the substrate will change after being heated. That is, under the same traction force, the stretching degree of the substrate will also be different, which is not conducive to subsequent processing and is not conducive to ensuring production quality.

[0003] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0007] Furthermore, the machine is equipped with an adjusting mechanism, an adjusting end of the adjusting mechanism is connected to the pressure roller drive, and the adjusting mechanism is used to drive the pressure roller to approach or move away from the cooling roller.

[0008] Furthermore, the hot stamping film heating and compounding mechanism comprises a heating roller rotatably connected to the machine platform and a compounding roller rotatably connected to the machine platform, the heating roller and the compounding roller are arranged in parallel, and a compounding gap is arranged between the heating roller and the compounding roller.

[0009] Furthermore, a fifth guide roller is arranged between the hot stamping film unwinding mechanism and the feeding end of the composite gap, and a sixth guide roller is arranged between the protective film winding mechanism and the discharging end of the composite gap.

[0010] Furthermore, the machine is equipped with a color mark sensor, which is located at the feeding side of the digital hot stamping gold varnish mechanism, and the digital hot stamping gold varnish mechanism is electrically connected to the color mark sensor.

[0011] Furthermore, the cooling roller is a water-cooled roller.

[0012] The beneficial effects of the utility model are as follows: in practical application, the substrate is sequentially wound around the first guide roller, the second guide roller and the third guide roller, and passes through the digital hot stamping varnish spraying mechanism, the UV drying and cooling mechanism, and the hot stamping film heating and compounding mechanism. The digital hot stamping varnish spraying mechanism sprays hot stamping varnish on the substrate, and then the UV drying and cooling mechanism UV-cures the hot stamping varnish on the substrate and cools the substrate.

In the process of UV drying and cooling mechanism UV-curing and cooling the substrate after the hot stamping varnish is sprayed, the UV curing lamp UV-cures the hot stamping varnish on the substrate, and at the same time, the cooling roller cools the substrate. The substrate passes through the material gap, and the rotating drive mechanism drives the cooling roller to rotate. The rotating cooling roller cooperates with the pressure roller to convey the substrate to move. The utility model realizes digital spraying of hot stamping varnish on the substrate. While UV light curing the hot stamping varnish on the substrate, the substrate can be cooled in time to avoid the problem of traction and stretching caused by change in tension of the substrate after heating, thereby ensuring the quality of the substrate and the accuracy of subsequent thermal composite, and realizing the composite of the substrate and the hot stamping film.
