Label paper carrier

Abstract

The invention discloses a label paper carrier. The label paper carrier comprises a shape-retaining unit and a loading plate; the shape-retaining unit comprises a shape-retaining piece, a push piece, ajacking rod and a reset spring; a shape-retaining surface distributed around the center line of the shape-retaining piece as well as a sliding groove distributed around the center line of the shape-retaining piece are arranged on the shape-retaining piece; the push piece is embedded in the sliding groove and is protruded on the shape-retaining surface; the shape-retaining piece is fixedly connected with the loading plate; and the jacking rod is movably arranged on the loading plate in a sliding way. The label paper carrier prevents from bearing other functions by only realizing single liftingfunction, so that constraint of the label paper lifting height of the label paper carrier caused by blockage of parts of the label paper carrier is avoided, and the label paper carrier has large lifting height.

Description

technical field [0001] The invention relates to a marking paper carrier. Background technique [0002] Common joint cup products are mainly yogurt in small cups. In addition to the cup body, the packaging of this yogurt product also has a label paper attached to the surface of the cup body and a cover film attached to the mouth of the cup. The combination of label paper and cup body includes thermoplastic lamination and heat shrink lamination, and the two methods correspond to label paper of different materials. In the thermoplastic bonding method, the label paper of the cup body is placed in a curled state in the mold cavity required for cup body forming before extrusion molding. When the sheet is heated and extruded in the mold cavity, the label paper is pasted on the On itself; the curled state here refers to the short strip of label paper rolled into a three-dimensional tubular structure. Although the head and tail of the label paper overlap, they are not fixedly conne...

Problems solved by technology

[0006] The raised structure of the four air tubes used to push the marking paper is not located at the top of the air tube, but at the lower end of the air tube, so the range of movement of the raised structure on the air tube is limited by the working position of the top of the air tube and cannot obtain a higher position , the height that the label paper can reach when it is ejected is limited by the air tube, so that the air tube distributed in a raised position can only be applied to a standard paper of one height, which limits the existing technology for loading and outputting the label.
