Problems solved by technology

The printing plate roller is usually made of seamless steel pipe after surface treatment. Although it has the advantage of good printing effect, it has an important problem that the cost of plate making is too high.
Since the entire printing plate roll is a whole, whenever a printing pattern variety is replaced, the entire printing plate roll needs to be updated, which increases the production cost, especially for some small batches and multi-variety production. Different types of printing plate rollers not only greatly increase the cost, but also need to process corresponding printing plate rollers for different varieties, so the entire production cycle is prolonged

Embodiment Construction

[0013] See attached figure 1 , 2 , which is a preferred embodiment of the present invention, which includes: a drum-shaped layout 1, a printing plate pattern 11 is processed on the peripheral surface of the layout 1, and the pattern 11 can be a letterpress or an intaglio. An air expansion shaft 2 is installed in the layout 1 . The inflatable shaft 2 includes a shaft body 21 with a hollow pipe 20 and a rubber sleeve 27 wrapped outside the shaft body 21. The shaft body 21 is provided with an air inlet 26, and the two ends of the rubber sleeve 27 are tightened by fasteners 271. On the shaft body 21 , a through hole 22 communicating with the internal hollow pipe 20 is defined on the surface of the shaft body 21 between the two fasteners 271 . The two ends of the shaft body 21 are formed with a central shaft 25 for transmission of the entire shaft body 21 , and the air inlet 26 can be opened on the central shaft 25 .

[0014] When in use, first, set the layout 1 outside the rubb...

Abstract

The invention relates to a printing roller and belongs to the printing equipment field. The technological scheme is: it includes the roller-shape printing face with the printing patterns processed on the circle surface of it and the gas-expansion shaft in the print face. The said gas-expansion shaft is the shaft core of the roller. The working principle is: the expansion of the gas-expansion shaft fills in the hollow tube of roller and makes the shaft and the print faces integrate to form the roller.

Description

Technical field: [0001] The invention relates to the technical field of printing equipment, in particular to a replaceable printing plate roller. Background technique: [0002] Traditional printing plate rolls include gravure printing and letterpress printing, which have the characteristics of multi-color continuous printing. The printing plate roll is usually made of a seamless steel tube after surface treatment. Although it has the advantage of good printing effect, it has an important problem that the cost of plate making is too high. Since the entire printing plate roll is a whole, whenever a printing pattern variety is replaced, the entire printing plate roll needs to be updated, which increases the production cost, especially for some small batches and multi-variety production. Different kinds of printing plate rollers not only greatly increase the cost, but also need to process corresponding printing plate rollers for different varieties, so the whole production cycl...
