Description
Technical Field
The invention relates to the technical field of printing, in particular to a printing device for preventing an original film from stretching and deforming under heating.
Background
The original film is a common plastic film and is widely applied to the integral assembly package of various products such as wine, pop cans, mineral water, various beverages, cloth and the like. In order to facilitate product promotion, component description and the like, characters and patterns are generally required to be printed on an original film in the production process. However, the original film is easily deformed after being stretched or heated, so that the printed characters and patterns are easily deformed, and the overall effect of product packaging is affected.
In order to solve the above problems, chinese patent (CN201761131U) discloses a thermal shrinkage film printing apparatus, which includes a first plate roller and a first press roller for matching printing, and further includes a pretreatment unit for stretching a thermal shrinkage film, so that the thermal shrinkage film is printed by the first plate roller and the first press roller after reaching a predetermined stretching amount through the pretreatment unit. The conventional printing process is added with a process of pre-stretching the heat-shrinkable film, and patterns are printed on the surface of the heat-shrinkable film after the heat-shrinkable film reaches a preset stretching amount. Therefore, when the pattern is printed on the heat-shrinkable film by the printer, the heat-shrinkable film has a certain expansion amount, and the subsequent deformation amount of the heat-shrinkable film is relatively small relative to the pre-expansion amount, so that the deformation amount of the heat-shrinkable film in the actual printing process is reduced, and the deformation amount of the pattern and the deformation amount in the actual printing process are within a controllable range, thereby obviously reducing the printing error of the heat-shrinkable film and improving the printing precision and the printing quality of the pattern.
Although the above patent scheme solves the problem that the original film printing process is easy to deform, the scheme still has some points to be improved: during printing, the lower part of the first plate roller is soaked in the ink, the ink reaches the whole first plate roller through the rotation of the first plate roller, and the redundant ink on the first plate roller is scraped through the scraper plate, so that the lower part of the first plate roller can be soaked only by using more ink in the whole process, and the input cost is increased; meanwhile, the ink is usually in an open state in the air, and is easy to volatilize due to more organic components contained in the ink, so that the air quality is influenced, and the printing environment is poor; in addition, moisture and impurities in the outside air under the opening easily enter the ink, dilution and pollution are caused to the ink, and poor printing quality is caused.
