Environmentally friendly label sheet printing process and printing equipment thereof

Abstract

The invention belongs to the technical field of label production and machining and particularly discloses an environmentally friendly label sheet printing process and printing equipment thereof. A fixed frame, a winding roll, an unwinding roll, a first pressing roll, a second pressing roll, an auxiliary roll and code spraying equipment are included. The unwinding roll is rotationally connected tothe left end of the fixed frame through a rotary shaft. The winding roll is rotationally connected to the middle of the fixed frame through a rotary shaft. The first pressing roll is rotationally connected to the left end of the fixed frame through a rotary shaft, and the winding roll is driven by a motor. According to the environmentally friendly label sheet printing process and the printing equipment thereof, an adhesive sticker can be flattened from the middle to two sides, thus distribution uniformity of the adhesive sticker is improved, and the problems that the adhesive sticker is not distributed evenly, consequently partial bulges appear in the label paper pasting process, the content of the adhesive sticker on the periphery is low, and the edge of label paper warps are prevented. Meanwhile, a first scraper blade is designed in an arrow shape and is matched with elastic design of a rubber block, and the conditions that high pull force is generated by a flattening plate to the label paper in the flattening process of the adhesive sticker, and consequently the label paper is damaged can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of label production and processing, and in particular relates to an environmentally friendly label face sheet printing process and printing equipment thereof. Background technique [0002] A label is a printed matter used to mark product goals, categories or content, making it easy for users and manufacturers to find and locate target products. The so-called labels in the printing industry are mostly printed matter used to identify the relevant instructions of their own products, and most of them are self-adhesive on the back. [0003] In the prior art, in the label production process, inkjet printing and gluing are usually carried out separately, which leads to the need to heat the label paper appropriately during gluing to improve the activity of the self-adhesive, thereby improving the adhesiveness of the self-adhesive. The adhesion strength of the label paper, and the addition of gluing and heating, the...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, to solve the waste of heat resources in the label production process, the phenomenon of unevenness and edge warping of the label after the label is pasted, and the waste of resources and environmental pollution caused by the loss of excess stickers, the invention proposes a A kind of environment-friendly label sheet printing process and its printing equipment
