Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive production technology, and in particular to a mechanism for stabilizing the positioning of a self-adhesive core without backing paper. Background Technology
[0002] Currently, self-adhesive materials are widely used in various industries, with self-adhesive labels being the most common product. Traditional self-adhesive labels are generally produced by laminating a backing paper and a face paper together. When in use, the face paper is peeled off from the backing paper and pasted onto the corresponding item. Furthermore, to further reduce production and usage costs, there are considerations to adopt new types of backing paper-free self-adhesive labels, i.e., self-adhesive labels without a backing paper structure.
[0003] In existing technologies, the production process of backless self-adhesive labels often requires specialized equipment to rewind and slit the finished labels. During the rewinding process, a backless self-adhesive label mandrel is typically placed at the rewinding equipment as the winding center. With the cooperation of the rollers on the rewinding equipment, the backless self-adhesive label is continuously wound around this mandrel, forming a roll of self-adhesive label that is convenient for storage and transportation.
[0004] However, in the aforementioned fully automated winding process, multiple prepared backing paperless self-adhesive mandrels still need to be placed repeatedly on the winding equipment in turn. The existing manual operation is time-consuming and poses certain safety hazards. Furthermore, during placement, the backing paperless self-adhesive mandrels are prone to collisions with the rollers and the backing paperless self-adhesive itself, resulting in an unstable posture of the backing paperless self-adhesive mandrels when they reach the designated position. This can easily cause the winding position of the backing paperless self-adhesive to deviate, directly affecting the quality of the product. Utility Model Content

[0012] In another preferred embodiment, the attraction generating device is a powerful magnet.
