Problems solved by technology
[0004] The effect of cooling treatment is limited when the temperature is high in summer, and the increased production cost is high
However, the increase in the proportion of slow drying agent is prone to product quality problems, such as the phenomenon of unclean scraping and trailing lines

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] to 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...

The invention discloses an ink tank of a gravure printing machine with a cooling device. It is composed of a two-layer oil tank and a one-layer oil tank arranged in the second-layer oil tank and spaced from the second-layer oil tank. The gravure printing machine ink tank is provided with a cooling chamber body, the cooling chamber is provided between the second-layer oil tank and the first-layer oil tank, the cooling chamber is provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively connected with the water inlet pipe and the return water pipe. This technical solution uses the cold water flowing in the cooling chamber to cool down the ink in the second-layer oil tank and the first-layer oil tank in the ink tank, and the ink that flows back from the second-layer oil tank to the ink pump is also low-temperature ink. The above-mentioned low-temperature ink is composed of ink The pump is supplied to the oil tank on the first layer again, and the setting of the above-mentioned cooling cavity can effectively control the temperature of the ink in the oil tank, and solve the dry plate phenomenon well.
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...
