Printing roller for mounting of card book

Abstract

The invention discloses a printing roller for mounting of a card book. The printing roller comprises a metal roller shaft and a roller body, wherein the roller body is covered with an adhesive skin layer, through holes or round pits are uniformly distributed on adhesive skin, and diameters and distribution density of the through holes or pits are set with the viscose area for mounting of card bookinside pages as the standard. With addition of the soft adhesive skin, wear resistance and toughness of the surface of the roller body are improved, frictional damage of the card book surface can beavoided in an adhesive rolling process, roundly distributed adhesive-free areas are formed on an adhesive surface after adhesive rolling by means of the through holes or pits in the adhesive skin, sothat the phenomenon of stress concentration produced on the adhesive surface after the mounting is eliminated, and the card book made by the printing roller has stable quality, reliable performance and high flatness and cannot deform after long-term use.

Description

technical field [0001] The invention relates to a printing device, in particular to a printing roller for card-book mounting which can control the amount of gluing and avoid deformation after card-book mounting, and belongs to the field of printing equipment. Background technique [0002] Card books are mainly used to collect souvenirs such as stamps, coins, coins, etc. Due to the limitation of their use nature, the inner pages need to have thicker size, higher strength and hardness, better support, and not easy to deform. [0003] When the existing collection card book is made, its inner pages are evenly glued by rubber rollers with a smooth surface, and a mounting machine is used to mount them, and the inner pages are bound into a book after the mountings are completed. Although the smooth surface of the rubber roller is simple and uniform in gluing, it is not easy to control the amount of gluing, resulting in waste of glue. The product is beautiful. In order to improv...

Problems solved by technology

Although the smooth surface of the rubber roller is simple and uniform in gluing, it is not easy to control the amount of gluing, resulting in waste of glue. beautiful product

In order to improve the above problems, in recent years, anilox rolls have been used in the printing industry for gluing, and the density of the anilox distribution is used to control the amount of gluing, so as to achieve the purpose of finely controlling the gluing process, which effectively avoids the Problems such as waste of glue or dampness on the mounted pages, but in practice, it is found that due to the reticulated distribution of the glue, the stress of the glue after mounting will be linearly distributed, and the inner pages of the mounted card will be deformed, and the flatness is poor. Bring trouble to the long-term use process
