Description
Technical Field
The invention relates to the technical field of printing, in particular to a rubber roller for local ink supply.
Background
In the process of printing and ink conveying, the situation that the whole page is not required to be subjected to ink and only a plurality of local ink receiving lines are required can be frequently met, in the situation, if the whole ink transmission is continued, ink at the non-pattern part can not be transferred, the ink continuously performs middle fracture movement under the repeated rolling of an ink roller, so that a connecting material in the ink is very easy to volatilize, the ink is pulverized and dried, and under the action of the serial roller in serial motion, the dried ink is spread to the pattern part, so that the quality problems that the lines of a product are not in a dot shape and the like are caused.
For the situation, the traditional method is that a machine operator adopts a rubber tapping method to process, namely, the rubber surfaces of non-pattern parts of all rubber rollers in an ink set are cut off and only the pattern parts are reserved, so that only the pattern parts are used for transmitting ink, and the non-pattern parts are not used for transmitting ink, and the phenomenon that the product quality is influenced due to ink pulverization and dry and hard drying can be avoided.
But the tapping has the following disadvantages: 1. the workload is large, and the production efficiency is influenced: generally, one ink set consists of 6-8 rubber rollers, each rubber roller needs to be polished, time and labor are wasted, polishing needs to be performed temporarily when the rubber roller is replaced, and a machine only stops for waiting, so that the production efficiency is influenced; 2. the universality is poor: the polished rubber rollers can only be specially used for rollers and can only be used on the ink set with fixed variety, and once the whole set of polished rubber rollers of the variety is replaced, all the polished rubber rollers are scrapped; 3. influence the product quality: more or less rubber roller fines are carried on the polished rubber roller, and ink dots are easy to form when the rubber roller is transferred to a printing plate.
