Embodiment Construction
[0030] Below in conjunction with embodiment, further illustrate the present invention.
[0031] see figure 1 , figure 2 It can be seen that there is no cooling device in the two-layer oil tank 2 in the prior art.
[0032] combine image 3 , Figure 4 It can be seen that a gravure ink tank with a cooling device of the present invention is composed of a two-layer oil tank 2, a layer of oil tank 1 arranged in the two-layer oil tank 2 and spaced from the second-layer oil tank 2, and the gravure ink The tank is provided with a cooling cavity, the cooling cavity is set between the second layer of oil tank 2 and the first layer of oil tank 1, the cooling cavity is provided with a water inlet 5 and a water outlet 6, and the water inlet 5 and the water outlet 6 are respectively connected to the water inlet pipe and the return pipe connected.
[0033] The water inlet 5 and the water outlet 6 are connected to the quick interface 14 through rubber hoses; the quick interface 14 is co...

The invention discloses an intaglio printing press ink tank with a cooling device. The intaglio printing press ink tank with the cooling device is composed of a second-layer ink tank body and a first-layer ink tank body, wherein the first-layer ink tank body is arranged in the second-layer ink tank body and an interval is reserved between the first-layer ink tank body and the second-layer ink tank body. The intaglio printing press ink tank is provided with a cooling cavity which is arranged between the second-layer ink tank body and the first-layer ink tank body, and a water inlet and a water outlet are formed in the cooling cavity and communicated with a water inflow pipe and a water outflow pipe respectively. By the adoption of the technical scheme, flowing cold water in the cooling cavity is used for cooling ink in the second-layer ink tank body and in the first-layer ink tank body in the ink tank, ink flowing back to an ink pump from the second-layer ink tank body is low-temperature ink as well, and the low-temperature ink is supplied to the first-layer ink tank body again through the ink pump; and due to the arrangement of the cooling cavity, the temperature of the ink in the ink tank is effectively controlled, and the dry plate phenomenon is well solved.
Description
technical field [0001] The invention relates to a printing device, specifically a gravure ink tank with a cooling device. Background technique [0002] During the printing process of the gravure printing machine, in order to ensure that the volatile organic compound VOC of the product meets the standard, the temperature of the drying oven is set at a high level. The temperature of the ink will rise after the equipment is operated for more than 1 hour, and the layout will gradually appear to block the mesh holes and the printing of small characters is incomplete, which is often said Printing dry plate phenomenon. [0003] To solve the above problems, the prior art adopts two methods: one is to reduce the ambient temperature; the other is to continuously increase the proportion of the slow drying agent in the ink. [0004] Cooling treatment has limited effect when the temperature is high in summer, and the increased production cost is high. However, the increase in the propo...
