Production and preparation process of adhesive tapes

Abstract

The invention relates to a production and preparation process of adhesive tapes. An installation table, an adhesive application device, an adhesive leveling device, an adhesive scraping device and a cooling device are included. The adhesive application device is installed on the left side of the upper end of the installation table, the adhesive leveling device is arranged on the right side of theadhesive application device, the adhesive scraping device is installed on the right side of the upper end of the installation table, and the cooling device is installed on the right side of the upperend of the installation table. The production and preparation process of the adhesive tapes can solve the problems that some areas are prone to adhesive leakage or excessive adhesive coating when plastic films are coated with the adhesives by rollers during adhesive application to the adhesive tapes by existing adhesive tape production equipment; too many adhesives are wasted due to the fact thatthe adhesives are applied unevenly and the temperature of the adhesives is too high as the adhesives are applied only once, and are naturally cooled normally after being applied.

Description

technical field [0001] The invention relates to the technical field of tape production and preparation, in particular to a tape production and preparation process. Background technique [0002] Adhesive tape is composed of base material and adhesive. Two or more unconnected objects are connected together by bonding. According to its function, tape can be divided into: single-sided tape, double-sided tape, insulating tape, Special tapes, die-cut tapes, etc., with different functions suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to the object. Early adhesives were mainly rubber; modern polymers are widely used. Adhesives need to be applied evenly on the substrate when producing tapes. [0003] Existing tape production equipment often has the following problems when applying glue to the tape: [0004] (1) When the existing adhesive tape production equipment is gluing the adhesive tape, the glue in the g...

AI Technical Summary

Problems solved by technology

[0004] (1) When the existing adhesive tape production equipment is gluing the adhesive tape, the glue in the glue pool is usually dipped by the roller, so that the roller with the glue rolls on the plastic film, so that the plastic film is glued. During the gluing process, glue leakage or excessive glue coating in some areas is easy to occur, which makes the excess glue discharged due to extrusion and winding during rewinding;

[0005] (2) When the existing adhesive tape production equipment applies glue to the adhesive tape, it usually only applies the glue once, and does not deal with the excess glue. After the glue is applied, it usually only cools the glue naturally, resulting in Uneven coating and high glue temperature lead to waste of glue in the tape production process and increase production costs
