Curved cup labeling method and device

Abstract

The invention discloses a curved cup labeling method and device. The labeling device comprises a base, a first machine cabinet and a second machine cabinet, wherein the first machine cabinet and the second machine cabinet are fixed on the base; the side, close to the first machine cabinet, of the outer wall of the top of the base is fixedly provided with a second motor through bolts; the outer wall of the side, close to the first machine cabinet, of the second machine cabinet is provided with a clamping groove; and the inner wall of the clamping groove is fixedly provided with a first motor through bolts. The curved cup labeling method comprises the following steps that S1, electrostatic film coating is conducted, and a labeling tape is driven by the first motor to enter a female die and electrostatically adsorbed to the outer side of a gap between the female die and a male die, namely the outer side of a cup wall. A label is flattened between the inner walls of the female die throughan L-shaped scraping surface, in cooperation with electrostatic adsorption, bubbles or wrinkles at the bonding positions are reduced, injection molding and labeling operation are integrated, the thickness of the cup wall can be regulated through a distance measuring positioner, bonding of the cup wall during plastic molding replaces traditional glue or an adhesive sticker, the labeling tightness is higher, and the water resistance is better.

Description

technical field [0001] The invention relates to the technical field of curved cup processing, in particular to a method and device for labeling curved cups. Background technique [0002] A water cup is usually a container for people to hold liquids, and can be used to drink tea, water, coffee, and beverages at ordinary times. A water glass is a vessel used to hold liquids in most cases. Usually made of plastic, glass, porcelain or stainless steel, when packing beverages in restaurants, they are often served in paper cups or plastic cups. The curved cup is a kind of cup in the water cup. Its side is different from the traditional cylindrical structure. The side is a curved cup wall. [0003] In the production of curved cups, it is necessary to label the cup wall. The existing labeling machines are glued between the self-adhesives, which may cause the label to wrinkle or curl at the corner of the label, which needs to be done manually. The labeling is smooth, but there are ...

Problems solved by technology

[0003] In the production of curved cups, it is necessary to label the cup wall. The existing labeling machines are glued between the self-adhesives, which may cause the label to wrinkle or curl at the corner of the label, which needs to be done manually. The labeling is smooth, but there are still bubbles or wrinkles, and there are unsafe problems in manual operation
