Substrate-free adhesive tape repasting equipment and adhesive tape repasting method thereof

Abstract

The invention discloses substrate-free adhesive tape repasting equipment and an adhesive tape repasting method thereof. The substrate-free adhesive tape repasting equipment comprises a circular knife machine, and a first station, a second station and a third station which are mounted on the circular knife machine, the number of the second stations is two, and the two second stations are arranged at the two ends of the circular knife machine. The first station is located on the left side of the third station. The first station comprises a first steel rod and a hot pressing roller which are positioned on the circular knife machine; wherein the space between the first steel rod and the hot pressing roller is used for feeding materials; the second station comprises a second steel roller and a rubber roller; and the space between the second steel roller and the rubber roller is used for feeding materials. The hot-pressing roller is utilized and heated, so that the activity of the double-faced adhesive tape can be improved, the double-faced adhesive tape can be quickly transferred and pasted to a low-gram-weight release film, the pre-pasting time is greatly shortened, and meanwhile, adhesive pulling and adhesive overflowing are avoided; the invention further discloses a repasting method of the base-material-free adhesive tape, so that the compounding effect of the base-material-free adhesive tape and the low-gram-weight release film is more ideal and reliable.

Description

technical field [0001] The invention relates to the technical field of tape transfer equipment and tape transfer method, in particular to a base material-free tape transfer device and a tape transfer method. Background technique [0002] Substrate-free double-sided tape is made of water-resistant kraft paper, white glassine paper or transparent PET that is directly coated with acrylic glue and then attached with polymer coating without any medium, such as PET, foam, cotton Therefore, it has the characteristics of good processability, good temperature resistance, good dimensional stability, thermal stability, chemical stability, and good initial viscosity and stickiness. [0003] Generally speaking, the conventional method, the use of non-substrate double-sided tape is to transfer to the 40-60g release film, and it also requires a long time of pre-lamination, if you want to transfer to a lighter weight release film However, the effect is not very ideal, and there may be unde...

Problems solved by technology

[0003] Generally speaking, the conventional method is to transfer to a 40-60g release film using double-sided adhesive without substrate, and it also requires a long time of pre-lamination. If you want to transfer to a lighter weight release film On the other hand, the effect is not very ideal, and there may be adverse phenomena such as product pull and glue wrinkle
