Description

Independent rotation driving device for two-station cup mold

Technical Field

The utility model relates to a plastic cup printing and conveying device, in particular to a two-station cup die independent autorotation driving device.

Background

The fast-consumption beverage packaging industry now takes plastic cups as the dominant, and along with the gradual development of the market and the change of demands, a plurality of new cup-shaped packaging materials are continuously emerging and are tried to be applied. The deficiencies and drawbacks of the cup printing devices of the current market manifest themselves during the course of the external demand changes.

For the change of cup type: many frosted high cups and high transparent cups appear on the market, and the cups can generate fine friction marks and influence the printing quality during the high-speed printing process due to high-speed sleeve mold and demolding.

Aiming at the structural change of the cup: market demand is diversified, cup printers are beginning to be used in some new packaging fields; a beverage cup with a special structure at the mouth part, wherein the position of the pattern relative to the cup is required to be fixed during printing;

for cup material changes: paper cups are applied to the market at present, but traditional paper cup surface patterns are printed in a plane before forming, and the paper cup surface patterns are updated with consumption and the iteration speed of products is increased, so that the traditional paper cup surface printing mode is obviously disadvantageous and cannot meet the requirement of small-batch rapid customization. Customized paper cup printing needs to ensure that the printed pattern is fixed with the paper cup seam. This is a new orientation of the cup press.

In view of the above problems, the cup mold rotation driving system of the current equipment has defects, and the current cup mold rotation driving system drives eight cup molds on the whole mold mounting plate to rotate simultaneously. For the problem of scratches, in this driving mode, for frosted high and high transparent cups, etc., the scratches can occur at the in-and-out stations: spiral scratches are generated at the moment that a non-rotating cup contacts with a cup mold rotating at a high speed at a cup feeding station; at the moment of the cup discharging station and the cup mold separating, the rotating speed of the cup is reduced because the cup mold keeps rotating at a high speed, and the speed difference is generated between the cup and the cup mold, so that scratches can be generated at the moment. The current drive configuration is clearly unsatisfactory for special configurations of cup printing or paper cup printing requiring the pattern to be circumferentially fixed relative to a location of the cup. The current cup driven by the driving structure is randomly jointed at the printing starting position or the special structure of the cup mouth, and the position fixing of the printed pattern cannot be ensured.
