Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tape gluing, in particular to a uniform gluing device. Background Art

[0002] According to its function, tape can be divided into: high temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cut tape. Different functions are suitable for different industry needs. It is easy to use and has a wide range of uses. A layer of adhesive is coated on the surface of the tape to make the tape stick to objects. In the 19th century, rubber was the main component of adhesives. In the production process of tape, a tape gluing device is usually used to automatically complete the gluing operation of the tape. When the existing gluing device is used, the glue on the surface of the tape is smoothed by the rotation of the gluing roller. However, the gluing roller lacks a scraping component and cannot scrape off the excess glue on the surface of the tape, which easily leads to uneven smearing of the glue on the surface of the tape, thereby affecting the gluing quality. Therefore, a uniform gluing device is proposed to solve the above technical problems. Utility Model Content
