Anti-spill and anti-adhesion joint of reel printing material as well as splicing method thereof

Abstract

The invention provides an anti-spill and anti-adhesion joint of a reel printing material as well as a splicing method thereof, and relates to the field of auxiliary supplies for production of reel printing materials. Through the change of a reel product joint and the improvement of a joint splicing method, the joint is prevented from overflowing adhesive under extrusion, the quality of the reel product and the stability of the subsequent processes are guaranteed and the production efficiency is improved to a certain degree; meanwhile, the joint operation time is shortened by virtue of the method simply, and the method is suitable for on-line operation. Through setting of the simple structure layer and low cost, the problems in the traditional printing industry are solved, the quality of the reel printing materials is improved, and succession of the subsequent processing of the reel printing materials, particularly reel cigarette labels is benefited; furthermore, the existing process isbasically not changed and the use cost is low.

Description

technical field [0001] The invention relates to the field of auxiliary supplies for the production of reel printed matter, in particular to an anti-spill and anti-stick joint and a splicing method. Background technique [0002] In the production process of reel trademarks, the products go through the slitting and rewinding process, and the parts with defects and defects need to be removed, and then the parts that meet the requirements are lapped and rewound into reels. The quality of the joints directly affects To the production efficiency and production quality of subsequent products. [0003] At present, tapes are usually used in the rewinding process of reel products. Specifically, the left and right joints are bonded together by tapes. There is an elastic adhesive layer. Although the thickness is very thin, generally less than 1mm, there is no problem under normal use. The tightness of the reel is high, and the pressure on the tape at the joint is huge, which will sque...

AI Technical Summary

Problems solved by technology

[0003] At present, tapes are usually used in the rewinding process of reel products. Specifically, the left and right joints are bonded together by tapes. There is an elastic adhesive layer. Although the thickness is very thin, generally less than 1mm, there is no problem under normal use. The tightness of the reel is high, and the pressure on the tape at the joint is huge, which will squeeze and deform the adhesive layer, causing it to overflow the base film layer, thereby polluting the reel trademark, causing them to stick to each other, and finally affecting the packaging molding, resulting in quality accidents

[0005] It can be seen that the focus of existing reel product joints is to ensure that the joints are firm, thin and easy to identify, but for reel products after multiple windings, squeezing the adhesive tape at the joints will squeeze the adhesive layer Defects such as spillage, contamination, and mutual adhesion were not addressed and no good solutions were proposed
