Description
Technical Field
The utility model belongs to the technical field of the printing, especially, relate to an ink supply unit for lithography apparatus.
Background
The indirect ink transfer printing is far less rapid than gravure immersion in the ink supply speed during printing. Therefore, the ink storage performance of the ink cavity influences the transferability of the ink on the printing surface, and the transferability directly causes whether the printing surface can be completely transferred to enough ink, so that a series of problems of incomplete printing, even missing printing, serious printing appearance defects and the like can be caused if the printing surface is insufficient. The ink supply system of the existing flexible printing machine is provided with ink return ports in the middle parts of two sides of an ink tank body, the plug-in type connectors arranged at the end parts of ink return branch pipes are directly connected, the ink return branch pipes on two sides are connected with an ink return main pipe connected with an ink storage box through a tee joint, and an ink cavity formed between the ink tank body and an anilox roller is communicated with the ink storage box. The existing ink supply system is easy to cause the problem of printing missing printing quality due to the fact that no ink is transferred to a printing surface after being transferred to a printing plate.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an ink supply unit for lithography apparatus that rational in infrastructure, simple manufacture, can not miss printing.
The utility model adopts the technical proposal that:
an ink supply device for printing equipment comprises an ink tank body, an ink cavity, a doctor blade, an ink sealing blade, an ink return port, an ink return branch pipe, an ink return main pipe, an ink storage box, an ink inlet and an ink inlet pipe, wherein the ink inlet is formed in the ink tank body, one end of the ink inlet is communicated with the ink cavity, the other end of the ink inlet is communicated with the ink storage box through the ink inlet pipe, and a diaphragm pump is arranged on the ink inlet pipe; the ink return openings are two and are arranged on the ink tank body, one end of each ink return opening is communicated with the ink cavity, the other end of each ink return opening is connected with an ink return branch pipe, the ink return branch pipes are connected with an ink main pipe through three-way joints, the ink return main pipe is connected with the ink storage box, and the ink inlet openings are arranged on the upper portion of the ink tank body and are higher than the position of the ink sealing knife when the ink inlet openings are communicated with the ink cavity.
The ink scraping knife, the ink sealing knife and the anilox roller form the upper part of an ink cavity, and an ink inlet pipe connected with an ink inlet is connected with the ink storage box through a diaphragm pump.
Furthermore, a throttle valve is additionally arranged on the ink return main pipe.
Through repeated tests and observation, the ink inlet is arranged in the middle of the ink tank body in the prior art, and the ink outlet position is close to the joint of the ink sealing knife and the anilox roller. In the ink feeding process, the ink chamber is in an ink-free state in a very short time under the impact force of the diaphragm pump, and the ink disturbance on the ink inlet of the ink chamber is large, so that the ink supply at the ink sealing knife and the anilox roller is insufficient instantly, the amount of ink finally transmitted to the anilox roller is reduced, and the ink transmitted to the printing plate roller is insufficient.
Meanwhile, the ink cavity is influenced by the ink backflow speed, and the condition that the amount of ink in the ink cavity is small is easy to occur.
The beneficial effects of the utility model reside in that: because the ink inlet is lifted to the upper part of the ink cavity and even to the highest point from the middle position of the ink tank body, the ink in the ink cavity can be ensured to be always in a full-filling state through the adjustment of the throttle valve, the impact force of the diaphragm pump in the ink inlet process at the joint of the ink sealing knife and the anilox roller is reduced, and the local ink break phenomenon on the anilox roller is effectively avoided. Meanwhile, a throttle valve is additionally arranged on the ink return main pipe to control the ink return speed, so that the ink cavity is always kept in a full ink state.
Use the utility model discloses behind the device, the printing speed of a motor vehicle can reach 105 ~ 200 meters/minute and do not have the phenomenon of missing printing to take place. The device has the advantages of reasonable structure, simple manufacture, stable operation, high quality, high efficiency and the like, effectively overcomes the quality problem of missing printing, and can be widely applied to the printing of tipping paper for various cigarettes.
The present invention will be further explained with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic view of the structure of the present invention;
fig. 2 is a left side view structure diagram of the present invention.
