Description

Technical Field

[0001] The utility model relates to the field of double-sided adhesive tape production, in particular to glue coating equipment for preparing double-sided adhesive tape. Background Art

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, with elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive evenly coated on the above base material. It consists of three parts: base material, adhesive, and release paper (film) or silicone oil paper.

[0003] Existing double-sided tape coating equipment generally uses a coating roller for coating. One end of the coating roller is in contact with the glue inside the glue storage box, and the other end protrudes from the glue storage box to coat the double-sided tape passing through. Although double-sided coating can be performed, the glue will become less and less as it is used. If it is not replenished in time, it will affect the coating effect and the practicality is poor.

[0004] Therefore, it is necessary to propose a glue coating device using double-sided adhesive to solve the above problems. Utility Model Content

[0017] Compared with the prior art, the utility model provides a glue coating device for preparing glue using double-sided adhesive tape, which has the following beneficial effects:

[0018] The glue coating equipment for preparing double-sided adhesive can realize glue coating on both sides of the double-sided adhesive through the mutual cooperation of the lower glue storage box, the lower glue coating roller, the upper glue storage box and the upper glue coating roller, thereby improving efficiency. The upper glue coating roller is arranged at the bottom of the upper glue storage box.
