Description

Automatic pressure real-time fine adjustment device of offset printing device

Technical Field

The utility model relates to an automatic real-time micromatic setting of pressure of offset printing device.

Background

The invention and development of the printing machine, which is a printing apparatus capable of printing desired characters, patterns and other information on the surface of a paper sheet, the contents to be printed by the paper sheet printing machine are first formed into printing plates and then mounted on the printing machine, and then ink is uniformly applied to the printing plates by the printing machine operated by a person, thereby reproducing the same printing copies as the printing plates, is important for the spread of human civilization and culture.

Cardboard printing machine can meet the cardboard of different thickness when printing, consequently change the roller and need pressurize or decompress and adapt to the cardboard of different thickness, current cardboard printing machine pressure device adjusts inconveniently, and current cardboard printing machine pressure device pressor synchronism is relatively poor, simultaneously because the thickness of different cardboard is different, in feed inlet department, the phenomenon of skidding takes place easily, thereby make the content of printing take place to squint or fuzzy, influenced cardboard printing machine's use printing effect.

Corrugated boxes are the widest packaging product in paperboard applications, and the amount of corrugated boxes is always the first of various packaging products. Corrugated carton packaging gradually replaces some traditional products as a mainstream product of green packaging, the application range of the corrugated carton packaging is wider and wider, and the corrugated carton packaging gradually replaces transport packaging containers such as wooden cartons and the like due to the excellent service performance and good processing performance of the corrugated carton packaging for more than half a century, so that the corrugated carton packaging becomes a prime force of transport packaging. It not only protects the goods, is convenient for storage and transportation, but also beautifies the goods and publicizes the goods. The corrugated case belongs to green environmental protection product, and it does benefit to the environmental protection, does benefit to the loading and unloading transportation.

In the production process of the corrugated case, patterns and characters need to be printed outside the case, in order to ensure the convenience of printing, the corrugated board for manufacturing the case is printed, and then the corrugated board is cut into a structure with a split case body. The printing device of the corrugated case adopts the printing roller to print the cardboard of the case body, the action of the rubber roller of the rotary offset printing machine in the printing process is crucial, whether the pressure of the rubber roller to paper is proper or not directly influences the printing effect, the pressure of the rubber roller is adjusted by manually adjusting the eccentric sleeves at two ends of the rubber roller shaft at present, but the adjusting mode is limited by the processing precision and the manual adjusting error twice, the pressure at two ends of the rubber roller cannot be ensured to be completely same, the rubber roller is easy to damage when the pressure at two ends of the rubber roller is unequal, and the manual adjusting mode has no feedback effect, if the cleaning and maintenance are improper in the actual production, paper scraps are adhered on the working surfaces at two ends of the rubber roller or the rubber roller is locally aged, so that the diameter of a certain position of the rubber roller is changed, a worker cannot know information in time, and can judge the fault of the rubber roller only when observing that a printed product has an error, the information feedback is delayed, the cost is wasted, and the automation degree is low.

Therefore, we propose an automatic pressure real-time fine-tuning device of an offset printing device to solve the above problems.
