A labeling machine pressing device

Abstract

The invention discloses a labeling machine downward pressing device, which comprises a machine frame, a conveying belt and a downward pressing mechanism, wherein the conveying belt is arranged on the machine frame; the downward pressing mechanism comprises an ascending and descending mechanism and a downward pressing component; the downward pressing component comprises a case, a belt assembly, a fixing frame and downward pressing elements; a plurality of downward pressing elements are in parallel arrangement; each downward pressing element comprises a movable rod arranged on a fixing frame, a T-shaped press head fixedly arranged at the lower end of the movable rod and an elastic element arranged on the movable rod; the press heads are positioned above the lower layer of a synchronous belt. Through a plurality of movable press heads, an irregular product at the upper end can be effectively pressed down, the downward pressing effect is good, each press head is provided with an elastic element, the downward pressing effect can be improved, and the downward pressing effect is fitter. The press heads are tensioned through a tensioning belt, and the position staggering between the press heads in the downward pressing process is avoided.

Description

technical field [0001] The invention belongs to packaging and labeling equipment, in particular to a pressing device for a labeling machine. Background technique [0002] During the labeling process of the product, it is sometimes necessary to press the product in the transmission process and then label it, so as to avoid the poor labeling due to product shaking or offset. For products with a flat upper surface, the pressing method is relatively simple. But a row of bottles, due to the defects of the production process, the height of each bottle will be slightly different, that is, the upper end of some bottles is slightly higher, and the upper end of some bottles is slightly lower. It is difficult to effectively press the product with a flat-bottomed pressing plate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressing device for a labeling machine, which can press down products with irregular upper surfac...
