A gravure printing water-based ink constant temperature control device

Abstract

The invention discloses a gravure water-based ink constant temperature control device, which comprises a cooling water tower, a main water inlet pipe, a main water outlet pipe, a high pressure resistant water inlet cooling pipe, a high pressure resistant water outlet cooling pipe, a cooling water bucket, a cooling copper pipe and an adjustable thermal expansion valve; the cooling copper pipe is fixedly arranged on the inner side wall of the cooling bucket through the water inlet joint and the water outlet joint, and the high pressure resistant water inlet cooling pipe and the high pressure resistant water outlet cooling pipe respectively The water inlet joint is connected with the water outlet joint, the main water inlet pipe and the main water outlet pipe are respectively connected with the cooling water tower, the high pressure resistant water inlet cooling pipe is connected with the main water inlet pipe, and the water resistant The high-pressure water outlet cooling pipe is connected to the main water outlet pipe, and the adjustable thermal expansion valve is arranged in the middle of the high-pressure resistant water outlet cooling pipe. The device can effectively reduce the temperature of the gravure water-based ink, and control it within the temperature range required by the process, so that the printability of the gravure water-based ink is more stable.

Description

technical field [0001] The invention relates to the field of gravure printing water-based ink, in particular to a gravure water-based ink constant temperature control device. Background technique [0002] With the acceleration of China's tobacco internationalization, my country not only imposes strict limits on various harmful substances in cigarettes, but also puts forward higher-level requirements for the environmental protection of cigarette labels. Actively reducing and eliminating toxic residues in cigarette labels is a caring for consumers and a manifestation of social responsibility. The environmental protection development of cigarette labels is the core of the future development of cigarette labels. Green and environmental protection will become an unstoppable development trend of tobacco packaging. It is a foregone conclusion that non-environmental protection packaging materials will be gradually eliminated. [0003] The development and application of domestic env...

Problems solved by technology

[0003] The development and application of domestic environmentally friendly inks are still in their infancy, and most of the environmentally friendly inks have disadvantages such as unstable printing suitability and high prices. This is also an important reason for the slow application and development of environmentally friendly inks in my country.
