Description

Technical Field

[0001] The utility model belongs to the technical field of label processing, and in particular relates to a self-adhesive coating structure for label processing. Background Art

[0002] When labels are processed and produced, self-adhesive stickers need to be coated on the back surface of the label to make it have a certain degree of stickiness. Generally, the coating device is composed of a self-adhesive roller at the bottom of the label and a pressure shaft roller at the top of the label. The self-adhesive roller and the pressure shaft roller cooperate to extrude and coat the label. Although it can meet the general usage requirements, it is easy to produce wrinkles during coating, which will affect the uniformity and effectiveness of the coating, and it will also affect the quality of the coating, and its applicability and practicality are limited. Utility Model Content

[0003] The utility model aims to provide a self-adhesive coating structure for label processing which has reasonable structural arrangement and is conducive to improving the uniformity of gluing.

[0004] The technical solution to achieve the purpose of the utility model is a self-adhesive coating structure for label processing, comprising a bracket, a glue box and a reeling shaft arranged on the bracket, a glue coating roller arranged on the bracket and with the bottom end extending into the glue box, a pressing roller arranged on the bracket and directly above the glue coating roller, a tensioning roller arranged on the bracket, an electric telescopic rod arranged on the bracket, and a circular opening piece fixed to the top of the electric telescopic rod;

[0005] The annular expansion piece is located between the tensioning shaft roller and the pressing shaft roller and is attached to the bottom surface of the label belt;

[0006] The diameter of the annular expansion piece matches the width of the label tape;

[0007] A rubber shaft is arranged above the tensioning shaft roller, the rubber shaft is attached to the upper surface of the tensioning shaft roller, and the label belt is located between the tensioning shaft roller and the rubber shaft.

[0008] Further preferably, the top surface of the annular expansion piece is provided with a rubber guide strip inclined outwards.

[0009] Further preferably, a driving motor connected to the glue coating roller is fixed at the end of the bracket.

[0010] Further preferably, the surface of the pressure roller is wrapped with a rubber sleeve layer.

[0011] It is further preferred that: a lifting platform is provided on the bracket, and the glue box is provided on the lifting platform;

[0012] A lifting electric rod is arranged between the lifting platform and the bracket.

[0013] It is further preferred that: a switch panel is provided on the bracket.

[0014] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the label tape can be tightened by arranging a tensioning shaft roller in cooperation with a pressing shaft roller, and then cooperates with the annular support piece. When the label tape is transmitted, the bottom surface of the label tape will pass through the camel annular support piece. Since the entry end is smaller than the width of the label tape, and the label tape is unfolded when the label tape is transmitted, it can effectively prevent the edge of the label tape from folding, so that the label tape entering the glue coating shaft roller is in a flattened state, which is beneficial to improving the uniformity of glue coating, and can also improve the quality of glue coating, and has strong applicability and good practicality.

[0023] In actual application, the annular expansion piece is located between the tensioning shaft roller and the pressing shaft roller and is attached to the bottom surface of the label tape; the diameter of the annular expansion piece matches the width of the label tape; a rubber shaft 9 is arranged above the tensioning shaft roller, the rubber shaft is attached to the upper surface of the tensioning shaft roller, and the label tape is located between the tensioning shaft roller and the rubber shaft. The rubber shaft and the tensioning shaft roller can ensure that the label tape is always in a tensioned state, which is conducive to flattening and subsequent glue spraying operations.

[0024] In actual application, the top surface of the annular expansion piece is provided with an outwardly inclined rubber guide strip 10. By providing the rubber guide strip, the folded edge can be guided outwardly to be unfolded, thereby ensuring the uniformity and effectiveness of subsequent gluing.
