Header mechanism of full-automatic labeling machine

Abstract

The invention provides a header mechanism of a fully automatic labeling machine, including a header plate and an unwinding frame support plate; a circular material tray and a brake mechanism; the circular material tray is arranged on the unwind frame support plate; the brake mechanism Including the brake shaft, brake lever, brake rubber, and the first roller; the brake shaft is set on the support plate of the unwind frame; the brake lever is located between the support plate of the unwind frame and the circular material tray, and can be placed on the support plate of the unwind frame Move in the gap with the circular material tray, the proximal end of the brake lever is connected to the brake shaft, the far end of the brake lever extends downward to the right and protrudes outward relative to the edge of the circular material tray; the first roller is arranged on the brake lever The far end; the brake rubber is set at the position where the center line of the section of the brake lever is deflected to the left, and is close to the lower edge of the circular material tray; it also includes the pressing film, the second roller, and the standard electric eye mechanism; the pressing film It is located under the first roller; the second roller is located on the right side of the first roller; the marking electric eye mechanism is located under the second roller.

Description

Technical field [0001] The invention relates to the technical field of labeling machines, in particular to the label head mechanism of a fully automatic labeling machine. Background technique [0002] The card labeling machine is suitable for labeling on the surface of various plastic sheets. Its applicable industries include electronics, hardware, plastics, chemical industries and other industries. Application examples include cardboard, acrylic board, large plastic parts and ceramic sheets, and suitable labels Mainly include self-adhesive labels, self-adhesive films, electronic supervision codes, barcodes, etc. [0003] At present, there are patent documents with publication number CN204124460U and patent documents with publication number CN205470192U respectively disclosing high-speed card labeling machines and fully automatic card labeling machines. The marking head mechanism of the above labeling machine needs to pass through at least four rollers, including a brake roller, b...

AI Technical Summary

Problems solved by technology

[0005] However, the inventor found in practice that before the labeling tape is measured, the travel path of the labeling tape is relatively complicated, and the resistance encountered during the travel process is large, resulting in frequent occurrence of broken tapes on the labeling tape

Moreover, due to the relatively complicated travel path of the labeling tape, the number of rollers and pressing sheets is too large, which makes it relatively difficult to maintain the labeling tape after the tape breaks.
