Problems solved by technology

[0002] Flexographic printing refers to the printing method that uses an elastic relief printing plate to transfer ink to the surface of the substrate. In normal use, since the ink fountain roller is required to transfer the ink from the ink fountain to the anilox roller, the ink needs to form a layer on the surface of the ink fountain roller. The ink layer, and rotates with the rotation of the ink fountain roller, is likely to cause ink loss and odor divergence, resulting in a reduction in ink quality, harm to the physical and mental health of surrounding operators, and waste of ink, and the gas in the external environment may also Mixed in, the generated air bubbles entering the nozzle will inevitably affect the inkjet effect
[0003] The ink is not only easy to volatilize, but also easy to solidify. If the temperature of the ink is too low, its fluidity will be deteriorated, which will reduce the work efficiency, and even cause blockage in severe cases. Because the ink covers the ink delivery device, it will cause external damage to the device. Heat insulation makes ordinary blowing heat dissipation ineffective. At the same time, blowing heat dissipation may blow external impurities and air bubbles into the ink, resulting in secondary pollution

Embodiment 1

[0026] This embodiment combines figure 1 , figure 2 and image 3 As shown, the integrated multifunctional flexographic printing inking device includes an ink fountain 1, the ink fountain 1 is equipped with ink 2, and a cylindrical ink fountain roller, the ink fountain roller is partially immersed in the ink 2, and the ink fountain roller From the outside to the inside, it includes a casing 3, an ink flow chamber 4 and a rotatable hollow cylindrical rotor 5. The curved wall of the casing 3 is provided with a number of ink outlet holes 9 communicating with the ink flow chamber 4. The ink outlet The holes 9 are arranged in a row and evenly distributed on the curved wall of the casing 3;

[0027] The rotor 5 is inscribed on the inner wall of the housing 3 obliquely below, and the rotor 5 is coaxially provided with a rotating shaft 6 and an annular cavity 12, the cavity 12 is arranged on the periphery of the rotating shaft 6, and the side of the cavity 12 The water inlet pipe 1...

Embodiment 2

[0039] This embodiment is further improved based on embodiment 1, as figure 1 As shown, the height of the soaked part of the ink fountain roller is higher than the maximum height of the ink inlet 10 and the ink return port 11 .

[0040] During use, the height of the soaked part of the ink fountain roller is higher than the maximum height of the ink inlet 10 and the ink return port 11, so that the ink fountain roller can absorb ink to the maximum every time, thereby improving efficiency, and the ink return is also directly in the ink fountain The ink of 1 is carried out under the liquid surface of 2 to prevent splashing and the distribution of ink mist.

Embodiment 3

[0042] This embodiment is further improved based on any one of Embodiments 1-2, such as figure 1 As shown, the rotating shaft 6 is connected with a variable frequency motor.

[0043] During use, the running speed of the rotating shaft 6 can be adjusted through the frequency conversion motor, thereby adjusting the ink output speed.

Abstract

The invention discloses an ink transporting device and particularly relates to an integrated multifunctional ink transporting device for flexographic printing. The integrated multifunctional ink transporting device for flexographic printing provided by the invention comprises an ink hopper. The ink hopper is filled with printing ink. The integrated multifunctional ink transporting device for flexographic printing also comprises a cylindrical ink foundation roller which is partially soaked in printing ink. The ink foundation roller successively comprises a shell, an ink flowing cavity and a rotatable hollow cylindrical rotor from outside to inside; a plurality of ink outlet holes communicating to the ink flowing cavity are formed in the curved surface wall of the shell and are arranged in an array and are uniformly distributed on the curved surface wall of the shell. According to the integrated multifunctional ink transporting device for flexographic printing disclosed by the invention,the temperature of the rotor can be controlled through the cavity, and on the one hand, a slip sheet and the rotor are prevented from deforming as the temperature is too high as a result of temperature accumulation in a long work time, an isolation area can play an isolating role, and parts are prevented from being damaged; on the other hand, when the printing ink is too low in temperature, the printing ink can be heated, so that the printing ink is not congealed, and the printing ink can flow smoothly, and therefore, the work efficiency is accelerated.
