The utility model relates to the technical field of printing ink stirring, and discloses a printing ink stirring storage tank with a heat preservation function, which comprises a tank body and a motor arranged at the top of the tank body, a coil heat conduction pipe is sleeved on the outer side of the tank body, and one end of the coil heat conduction pipe is communicated with a water pump. The water inlet end of the water pump communicates with a water heater, the other end of the coil heat conduction pipe communicates with a temperature control system, and the other side of the temperature control system communicates with the water heater; the hot water circulation system is used, the temperature in the stirring tank is maintained through continuous hot water flowing, hot water circulation can ensure that the temperature in the ink stirring tank is stable, the change of ink performance caused by temperature fluctuation is avoided, and the stable temperature environment is beneficial to maintaining the viscosity, fluidity and other characteristics of ink; therefore, the printing or coating effect is improved; through hot water circulation, heat can be uniformly distributed to all parts of the stirring tank, uniform mixing of printing ink is facilitated through uniform heating, and the stirring effect is improved.

This application provides an ink formulation and process for improving the stability of gravure proofing production, relating to the field of printing technology. The ink formulation provided in this application includes 60-70% binder, 10-18% pigment, 0.5-1% defoamer, 1.5-3% filler, 1-3% alcohol solvent, and water as the balance. The filler is silane coupling agent-modified calcium carbonate; the binder is an aqueous acrylic emulsion or polyurethane emulsion with a mass ratio of (30-85):(15-70). This polyurethane emulsion is prepared by reacting aliphatic diisocyanate and L-lysine diisocyanate with a polyol, and a 3-methoxy-4-hydroxymandelic acid chain extender is introduced. Using this ink formulation for printing avoids the low production efficiency and increased production costs caused by repetitive labor, achieving stable gravure printing production. The printed products have uniform and stable color, high adhesion, and good durability.

The invention discloses a full-automatic printing system, relates to the technical field of automatic printing, and solves the problem that ink on the surface of a printed matter is easily scratched, smeared and even worn. And meanwhile, the problem of low product printing efficiency is solved. The full-automatic printing system comprises a machine box, an upper frame, an automatic printing assembly and an integrated conveying and shaping mechanism, the upper frame is installed at the top of the machine box, the automatic printing assembly installed at the edge of the top of the machine box is arranged on the inner side of the upper frame, and the automatic printing assembly conducts automatic printing operation on products; and an integrated conveying and shaping mechanism is mounted in the center of the top of the case. According to the printing device, the printed and moved product is subjected to automatic air-drying and shaping pretreatment, it is guaranteed that printing ink printed to the surface of the product can be more stably bonded with the product, and the problems that the printing ink is scratched, smeared, even abraded and the like due to vibration force and friction force of the operation are solved; and the quality of the printed product is effectively improved.
