Description

Technical Field

[0001] This utility model belongs to the field of printing press technology, specifically relating to a satellite flexographic printing press with a water-based ink uniform coating device. Background Technology

[0002] The satellite flexographic printing press is a type of flexographic printing equipment that uses a central impression cylinder (satellite cylinder) as its core structure. Its key feature is that multiple printing color units are arranged around a single large-diameter impression cylinder. The substrate moves in close contact with the cylinder during printing, ensuring high registration accuracy and stable tension. It is particularly suitable for continuous high-speed printing of flexible packaging materials such as films and paper. This model boasts advantages such as high printing speed, vibrant colors, and wide adaptability, and is widely used in food packaging, labeling, and corrugated paper pre-printing.

[0003] In the operation of a satellite flexographic printing press, ink is sprayed onto the surface of the rollers through an inkjet system for printing. However, when the ink volume is too large, the excess ink will drip down the roller surface because it cannot be fully utilized, resulting in ink waste, reduced ink utilization, and increased production costs. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a satellite flexographic printing press with a water-based ink uniform coating device, comprising:

[0027] The printing mechanism 100 includes a mounting base 110, a central impression cylinder 120 and a take-up and untake-up frame 130 respectively fixedly mounted on the top of the mounting base 110, a fixing plate 140 disposed inside the central impression cylinder 120, an oil storage tank 150 fixedly mounted on the top of the fixing plate 140, a plurality of nozzles 160 disposed at the bottom of the fixing plate 140, and a printing roller 170 disposed below the fixing plate 140 and used in conjunction with the nozzles 160.

[0028] The ink recycling unit 200 includes a recycling component 210 for collecting and utilizing ink, and a cleaning component 220 for cleaning the printing roller 170.

[0029] The recycling component 210 is used to collect and utilize excess ink, which solves the problem of ink waste caused by excessive ink spraying in traditional printing presses and improves ink utilization. The cleaning component 220 is used to clean the residue on the surface of the printing roller 170 when the machine is stopped, so as to avoid excessive residue from accumulating on the surface of the printing roller 170 and affecting the normal use of the printing roller 170.

[0030] Specifically, the recycling component 210 includes two scrapers 211 disposed on the surface of the printing roller 170, and a side plate 212 fixedly installed between the two scrapers 211.

[0031] When the nozzle 160 sprays ink into the interior of the printing roller 170, the ink adheres to the surface of the printing roller 170. When there is a lot of ink, the ink can be collected between the two scrapers 211 through the cooperation between the scraper 211 and the side plate 212, so that the ink can be continuously used by the printing roller 170, avoiding ink waste and improving ink utilization.

[0032] Furthermore, a number of connecting rods 213 are fixedly installed on the surface of the fixing plate 140, and the other end of the connecting rods 213 is fixedly connected to the top of the scraper 211.

[0033] The connecting rod 213 is used to install and fix the scraper 211, thereby improving the installation stability of the scraper 211.

[0034] Preferably, the two scrapers 211 are inclined, and the side plate 212 fits the surface of the printing roller 170.

[0035] By setting the scraper 211 to an inclined position, firstly, it can effectively remove residues from the surface of the printing roller 170, preventing excessive residues from affecting the normal use of the printing roller 170; secondly, it can collect excess ink so that it can be evenly applied to the surface of the printing roller 170 again.

[0036] Furthermore, the cleaning component 220 includes two main pipes 221 disposed around the printing roller 170, a plurality of nozzles 222 disposed on the surface of the main pipes 221 for cleaning the surface of the printing roller 170, and a connecting bend 223 communicating with the surface of the main pipes 221.

[0037] The cleaning fluid is pumped out at high speed by the pump body and introduced into the interior of the connecting bend 223 through the water inlet pipe 224. Under the action of the pulse valve 225, the cleaning fluid is intermittently delivered. The connecting bend 223 introduces the cleaning fluid into the interior of the main pipe 221 from both ends. Finally, the cleaning fluid is intermittently sprayed into the interior of the printing roller 170 through the spray nozzle 222 to clean the residue on the surface of the printing roller 170.

[0038] Specifically, the surface of the connecting bend 223 is connected to an inlet pipe 224 for water intake, and a pulse valve 225 is fitted onto the surface of the inlet pipe 224.

[0039] The pulse valve 225 is triggered by an instantaneous electrical signal, thereby enabling the nozzle 222 to spray intermittently, so as to improve the cleaning effect on the surface of the printing roller 170.

[0040] Furthermore, the other end of the inlet pipe 224 is connected to the output end of the pump body.

[0041] When in use, when the nozzle 160 sprays ink into the interior of the printing roller 170, the ink adheres to the surface of the printing roller 170. When there is a lot of ink, the ink can be collected between the two scrapers 211 through the cooperation between the scraper 211 and the side plate 212, so that the ink can be continuously used by the printing roller 170.

[0042] The pump body pumps the cleaning fluid out at high speed and introduces it into the interior of the connecting bend 223 through the inlet pipe 224. Under the action of the pulse valve 225, the cleaning fluid is delivered intermittently. The connecting bend 223 introduces the cleaning fluid into the interior of the main pipe 221 from both ends. Finally, the cleaning fluid is intermittently sprayed into the interior of the printing roller 170 through the spray nozzle 222 to clean the residue on the surface of the printing roller 170.

[0043] In summary, the recycling component 210 is used to collect and utilize excess ink, which solves the problem of ink waste caused by excessive ink spraying in traditional printing presses and improves ink utilization. The cleaning component 220 is used to facilitate the cleaning of residues on the surface of the printing roller 170 when the machine is stopped, preventing excessive residues from accumulating on the surface of the printing roller 170 and affecting its normal use.
