Printing system of self-adhesive label

Abstract

The invention discloses a printing system of a self-adhesive label. The printing system comprises a paper releasing unit, a printing unit and a paper collecting unit, wherein the head and tail ends of printing paper are respectively rolled on the paper releasing unit and the paper collecting unit; the printing unit is arranged on the printing paper between the paper releasing unit and the paper collecting unit; a film pasting unit is arranged on the printing paper between the printing unit and the paper collecting unit; the film pasting unit comprises a front side glue spreading roll positioned on the front side of the printing paper; a film pasting roll is arranged on the back side of the front side glue spreading roll; a film releasing roller is arranged above the film pasting roll; a press roll is arranged on the back side of the film pasting roll; and a film pasting platform is arranged on the reverse side of the printing paper below the film pasting roll and the press roll. The invention provides the printing system in which the printed self-adhesive label does not need release paper, a protective film is pasted on the front side of the self-adhesive label, and the protective film of the rolled self-adhesive label isolates the front side of the printed self-adhesive label from the reverse side of glue, so that the printing quality of the front side of the self-adhesive label is not influenced, and the normal use of the self-adhesive label is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of label printing systems, and more specifically relates to a self-adhesive label printing system. Background technique: [0002] Self-adhesive is a kind of material, also called self-adhesive label material. It is a composite material with paper, film or other special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. And after printing, die-cutting and other processing, it becomes a finished label; it has the advantages of no glue brushing, no paste, no dipping in water, no pollution, and saving labeling time. It has a wide range of applications and is convenient and quick. Existing self-adhesive labels include surface paper and release paper. The surface paper is the carrier of printed characters and patterns. The release paper is used to carry the surface paper. It brings great convenience, but its defect is obvious, that is, the utilization rate of...

Problems solved by technology

Existing self-adhesive labels include surface paper and release paper. The surface paper is the carrier of printed characters and patterns. The release paper is used to carry the surface paper. It brings great convenience, but its defect is obvious, that is, the utilization rate of paper is not high, less than 50%, because the release paper is to be treated as waste paper, thus a kind of linerless paper is proposed The concept of self-adhesive label is to remove the release paper of self-adhesive

However, the simple bottomless label paper only has adhesive on the bottom surface of the label paper, so that when the label is rolled, it will stick to the front of the label paper, which will affect the normal use of the label.
