Description

Technical Field

[0001] The invention relates to the technical field of flexographic printing presses, in particular to a multifunctional horizontal flexographic printing press. Background Art

[0002] The flexographic printing machine mainly consists of four parts, namely the unwinding feeding part, the printing part, the drying part and the rewinding receiving part. In modern flexographic printing machines, there are generally measurement and control devices such as tension control, edge position control, registration control, and printed product observation, as well as mechanical status monitoring and fault diagnosis systems. In addition, in order to expand the scope of application, some flexographic printing machines are also equipped with glazing, laminating, hot stamping, slitting, die-cutting, punching, silk screen and gravure units, etc., to become a flexographic joint production line. The application number is 202010569541.1, which discloses a printing mechanism of a flexographic printing machine. By setting a scraper on the mounting plate, the scraper can scrape off the ink on the blank rollers at both ends of the plate roller, and guide the ink into the ink cartridge to avoid ink contamination on the printing machine, ensure the cleanliness of the printing machine, and facilitate the user to clean the printing machine, solving the problem that the ink blocks accumulated on both sides of the printing plate are not conducive to cleaning.

[0003] There are many factors that may cause the ink to not be completely attached to the flexographic plate in the above scheme. Among them, the humidity in the environment can indirectly affect the corona unit in the production line. As the relative humidity of the air and the temperature of the film surface increase, the required corona treatment time becomes longer, that is, the film is less likely to be corona treated. Therefore, it does not meet the existing needs. We propose a multifunctional horizontal flexographic printing machine. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, after the unwinding unit unwinds the flexible plate, it directly enters the corona treatment unit, and uses high frequency and high voltage to perform corona discharge on the surface of the treated flexible plate to generate low-temperature plasma, so that the surface of the flexible plate generates free radical reaction to cross-link the polymer, the surface becomes rough and its wetting to polar solvents is increased. These ions enter the surface of the printed body through electric shock and penetration to destroy its molecular structure, and then oxidize and polarize the treated surface molecules. The ions erode the surface through electric shock, so as to increase the adhesion ability of the printed surface. The corona treatment unit is also provided with an independent environmental humidity management mechanism, which can control the humidity of the surrounding environment where the corona treatment unit is located, so as to reduce the influence of humidity on the corona treatment process, prevent ozone from dissolving in air moisture, thereby enhancing the corona effect on the surface of the flexible plate, and at the same time avoid the occurrence of liquid contamination;

[0017] 2. In the present invention, due to the decrease in ozone concentration, the chances of oxygen-containing functional groups being generated and electret on the membrane surface are greatly reduced, thereby reducing the effect of corona treatment. As the temperature of the membrane surface increases, the stability of the electret molecules deteriorates, and the proportion of surface molecular migration increases, which is not conducive to the formation of high surface energy areas on the membrane surface, and partially offsets the effect of increasing the surface tension of the film through corona. On the other hand, according to experience in actual production, the temperature of the membrane surface is not the lower the better. In production, the corona treatment process will generate a lot of heat. In order to prevent the membrane surface temperature from being too high, a circulating cooling tube is used in conjunction with a hollow metal corona roller for closed circulation. On this basis, a set of heating devices can be added to keep the cooling water at a certain temperature.

[0018] 3. In the present invention, the auxiliary heat-conducting air shaft is arranged at the entrance and the exit of both sides of the ionization chamber, wherein the auxiliary heat-conducting air shaft at the entrance is responsible for blowing the air heated and dried by the drying fan to the surface of the flexible plate, which can play a role of preheating and drying it, avoiding the problem of moisture on the surface of the flexible plate, and also avoiding the situation that the flexible plate with a lower temperature appears water mist on the surface after entering the cavity with a relatively higher temperature during the corona process, while the auxiliary heat-conducting air shaft at the exit is responsible for extracting the gas inside the cavity, which can drive the airflow at the output port, help the flexible plate to complete the cooling operation after the corona, and prevent the flexible plate from overheating and affecting the surface tension;

[0019] 4. In the present invention, an air flow gap is arranged between the high voltage electrodes on the surface of the high voltage power supply box. When the high voltage electrodes complete the ionization operation on the air, the residual ozone inside the cavity can be quickly extracted from the cavity surface through the air flow gap and the external duct air pump, and the extracted ozone is stored inside the duct air pump, thereby ensuring that the amount of ozone inside the cavity will not be excessive.

[0031] After the unwinding unit 1 unwinds the flexible plate, it will directly enter the corona treatment unit 2, and use high frequency and high voltage to perform corona discharge on the surface of the treated flexible plate to generate low-temperature plasma, so that free radical reaction occurs on the surface of the flexible plate to cause cross-linking of the polymer, making the surface rough and increasing its wetting to polar solvents. These ions enter the surface of the printed body through electric shock and penetration to destroy its molecular structure, and then oxidize and polarize the treated surface molecules. The ions erode the surface by electric shock, thereby increasing the adhesion ability of the printed surface. The interior of the corona treatment unit 2 is also provided with an independent environmental humidity management mechanism, which can control the humidity of the surrounding environment where the corona treatment unit 2 is located, so as to reduce the influence of humidity on the corona treatment process and prevent ozone from dissolving in air moisture, thereby enhancing the corona effect on the surface of the flexible plate, and at the same time avoiding the occurrence of liquid contamination.

[0034] Due to the decrease in ozone concentration, the chances of oxygen-containing functional groups being generated and electret on the membrane surface are greatly reduced, thereby reducing the effect of corona treatment. As the membrane surface temperature increases, the stability of the electret molecules deteriorates and the proportion of surface molecular migration increases, which is not conducive to the formation of high surface energy areas on the membrane surface, partially offsetting the effect of increasing the surface tension of the film through corona. On the other hand, according to actual production experience, the temperature of the membrane surface is not the lower the better. During production, the corona treatment process will generate a lot of heat. In order to prevent the membrane surface temperature from being too high, a circulating cooling pipe 2022 is used in conjunction with a hollow metal corona roller 205 for closed circulation.
