SUMMARY
[0003] The utility model discloses a kind of intaglio printing devices, to solve the problems mentioned in the above background technology.
[0004] To achieve the above object, the utility model adopts the following technical scheme: the intaglio printing device, including ink storage tank, the ink storage tank is provided with impression cylinder and plate cylinder, the plate cylinder is located below impression cylinder, the outside of the ink storage tank is respectively provided with the speed reducer for driving impression cylinder and plate cylinder rotation, the inside of the ink storage tank and below plate cylinder are provided with arc ink container, one end of the ink container is provided with scraping strip, the bottom of the ink storage tank is provided with ink outlet, further including pump body, the pump body has inlet and outlet, the inlet of the pump body is connected with the ink outlet, the outlet of the pump body is provided with pipeline, the ink container is provided with through hole, one end of the pipeline is fixed in the through hole of the ink container after penetrating the ink storage tank.
[0005] Preferably, the lower end of the ink storage tank is set into funnel shape, and the ink outlet is arranged at the bottom of the lower end of the ink storage tank.
[0006] Preferably, the through hole on the ink container is arranged on one side of the scraping strip.
[0007] Preferably, the upper end of the ink storage tank is provided with an end cap.
[0008] Preferably, the lower surface of the ink storage tank is provided with an electric heating module.
[0009] The utility model has the advantages that:
[0010] The device can continuously deliver the ink in the ink storage groove to the ink containing groove and make the ink in the ink containing groove return to the ink storage groove through the pump body circulation when in use, thereby avoiding the precipitation of the ink in the ink storage groove, improving the printing quality and ensuring the consistency of the printing effect. BRIEF DESCRIPTION OF DRAWINGS
[0011] Fig. 1 is a structural schematic diagram of a specific embodiment of the utility model.
[0012] Fig. 2 is a structural schematic diagram of the inside of the ink storage groove.
[0013] In the figure: 1, printing material; 2, ink storage groove; 3, impression cylinder; 4, plate cylinder; 5, speed reducer motor; 6, ink containing groove; 7, scraping strip; 8, ink outlet; 9, pump body; 10, pipeline; 11, end cover; 12, electric heating module. DETAILED DESCRIPTION
[0014] The specific embodiment of the utility model will be further explained in combination with the drawings.
[0015] As Figs. 1-2 shown, a gravure printing device includes an ink storage groove 2, the ink storage groove 2 is provided with an impression cylinder 3 and a plate cylinder 4, the plate cylinder 4 is located below the impression cylinder 3, the outside of the ink storage groove 2 is provided with a speed reducer motor 5 for driving the impression cylinder 3 and the plate cylinder 4 to rotate respectively, the inside of the ink storage groove 2 and below the plate cylinder 4 are provided with an arc-shaped ink containing groove 6, one end of the ink containing groove 6 is provided with a scraping strip 7, the bottom of the ink storage groove 2 is provided with an ink outlet 8, further including a pump body 9, the pump body 9 has an inlet and an outlet, the inlet of the pump body 9 is connected with the ink outlet 8, the outlet of the pump body 9 is provided with a pipeline 10, the ink containing groove 6 is provided with a through hole, one end of the pipeline 10 penetrates through the ink storage groove 2 and is fixed in the through hole of the ink containing groove 6.
[0016] The ink storage tank 2 stores a certain volume of ink inside, and when printing the printing material 1, the ink in the ink storage tank 2 is transported to the ink tank 6 through the pump body 9 and the pipeline 10, the ink in the ink tank 6 has a certain depth, so that the grooves on the outer surface of the plate cylinder 4 can be completely immersed in the ink in the ink tank 6, then the two speed reduction motors 5 drive the impression cylinder 3 and the plate cylinder 4 to rotate respectively, the rotation speed of the impression cylinder 3 and the plate cylinder 4 is the same, and the rotation direction is opposite, so as to realize the printing of the printing material 1, after the plate cylinder 4 is immersed in the ink in the ink tank 6, the plate cylinder 4 will pass through the doctor blade 7 before printing the printing material 1, the doctor blade 7 re-removes the excess ink on the outer surface of the plate cylinder 4 to the ink tank 6, so that the plate cylinder 4 only stores ink in the grooves after passing through the doctor blade 7, so as to cooperate with the impression cylinder 3 to realize the printing of the printing material 1, and as the ink in the ink tank 6 increases, the excess ink will overflow from the ink tank 6 and enter the ink storage tank 2, so as to be continuously pumped to the ink tank 6 by the oil pump.
[0017] Further, the lower end of the ink storage tank 2 is funnel-shaped, and the ink outlet 8 is arranged at the bottom of the lower end of the ink storage tank 2, so that the ink in the ink storage tank 2 can be collected at the bottom of the ink storage tank 2, thereby providing sufficient ink for the oil pump.
[0018] Further, the through hole on the ink tank 6 is arranged on one side of the doctor blade 7, so as to make the ink in the ink tank 6 flow from one side of the doctor blade 7 to the other side of the ink tank 6 as much as possible, thereby avoiding the problem that the local ink in the ink tank 6 has poor flowability for a long time.
[0019] Further, the upper end of the ink storage tank 2 is provided with an end cover 11, so as to reduce the pollution of impurities outside to the ink in the ink storage tank 2.
[0020] Further, the lower surface of the ink storage tank 2 is provided with an electric heating module 12, so as to heat the ink in the ink storage tank 2, thereby avoiding the problem that the normal use of the device is affected due to the reduced flowability of the ink in cold weather conditions.
[0021] In the description of the present application, unless otherwise clearly defined and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
