Coating, gluing and compounding device for production of thermosensitive offset paper

Abstract

The invention discloses a coating, gluing and compounding device for production of thermosensitive offset paper. The device comprises a film passing guide roller, a paper passing guide roller and a glue application roller and further comprises a gluing and compounding roller and a curling and correcting roller; base paper is guided by the paper passing guide roller and the curling and correcting roller to pass through the upper end of the gluing and compounding roller; a film is guided in by the film passing guide roller, passes through the space between the glue application roller and the gluing and compounding roller, then winds around the gluing and compounding roller and is compounded with the base paper at the upper end of the gluing and compounding roller, and the base paper and the film move together and wind around the curling and correcting roller; the gluing and compounding roller is located above the glue application roller and driven by the glue application roller to rotate; the lower part of the glue application roller is immersed in glue; a scraper is arranged on one side of the glue application roller and used for scraping the glue on the outer surface of the glue application roller; the film is guided by the film passing guide roller to make contact with the glue application roller firstly and then make contact with the gluing and compounding roller. The device is better in gluing uniformity and compounding synchronism, the manufacturing quality of the thermosensitive offset paper is effectively improved, curling of the thermosensitive offset paper can also be prevented, and the yield of products is increased.

Description

technical field [0001] The invention relates to manufacturing equipment for printing office consumables, in particular to a coating, gluing and compounding device for producing heat-sensitive version paper. Background technique [0002] Thermal master paper is a special consumable for digital all-in-one speed printing machines. It has the advantages of "high efficiency, convenience, environmental protection, and economy". It has a broad market prospect and is currently widely used in schools, institutions, enterprises, etc. unit. The manufacturing process of heat-sensitive paper is composed of gluing, compounding, drying, slitting, and packaging. Among them, the gluing and compounding processes are the most critical processes in the entire heat-sensitive paper manufacturing process. Control the most important link. Since there is no standard coating, gluing and compounding machine for producing heat-sensitive paper in China, each manufacturer designs and transforms itself ...

Problems solved by technology

The advantage of this method is that it does not require high synchronization of the machine, and the disadvantage is that the uniformity of gluing is poor, and it is only suitable for the production of low-end products that do not require high printing quality.

The other is the extrusion type forward gluing, that is, the direction of the film is consistent with the direction of the gluing roller, and the film passes through the gap between the gluing roller and the gluing roller to control the amount of gluing. The uniformity of gluing in this way Slightly improved, but because the mirror roller is used, the amount of gluing is also controlled by the gap between the sizing roller and the gluing roller. Affected by the mechanical precision, the control of the gluing amount is still not accurate enough

[0004] In addition, the existing coating, gluing and compounding machines for producing heat-sensitive paper usually use the film to be coated and glued, and then compounded with the base paper on other guide rollers. Some machines even go through After a few guide rollers are combined with the base paper, the quality of the compound is greatly affected by the synchronization between the guide rollers of the machine

[0005] To sum up, the existing coating, gluing and compounding machines for producing heat-sensitive paper still have unsatisfactory gluing uniformity, and it is difficult to accurately control the amount of gluing, which is greatly affected by machining accuracy and synchronous control stability. It caused problems such as low quality and low yield rate of the produced heat-sensitive version paper, which needs to be further improved
