Single-glue-layer plastic card applied to rapid diagnosis, and preparation method and equipment thereof

Abstract

The present invention discloses a single-glue-layer plastic card applied to rapid diagnosis, and a preparation method and equipment thereof. The method comprises the following steps: step one, flattening a plastic sheet; step two, simultaneously applying a non-drying glue onto release paper; and step 3: enabling the glue face of the release paper to face to the flattened plastic sheet, and performing rolling press to bond the non-drying glue layer of the release paper to the plastic sheet. The single-glue-layer plastic card includes the plastic sheet and the release paper which are adhered bythe non-drying glue layer. The equipment comprises a plastic-sheet reeling and unreeling roller, a release-paper reeling and unreeling roller, a constant-tension stretching device playing a role in both plastic-sheet reeling and rolling combination, a warm water tank, a cooling device and a non-drying glue applying roller and a drying tunnel. According to the invention, the flattening problem of the plastic sheet during a continuous feeding process is solved, the heating temperature is constant, the flattening effect is good, the detection card only need one layer of non-drying glue, a film isomitted, the cost is greatly reduced, the processing steps are fewer and adverse effects such as dust pollution is greatly improved.

Description

technical field [0001] The invention relates to a detection sheet for rapid diagnosis, also known as a plastic card, in particular to a single-layer rubber plastic card for rapid diagnosis and a manufacturing method and equipment thereof. Background technique [0002] The existing rapid diagnostic test sheet is a plastic card, and its structure includes a plastic sheet, double-sided adhesive tape and release paper. The double-sided adhesive tape is composed of a film in the middle and self-adhesive adhesive layers coated on both sides of the film. The processing of this plastic big card is to take a flattened plastic sheet at a time, spread it on the workbench, then paste the purchased double-sided adhesive on the plastic sheet, and then cover the release paper on the plastic sheet. on double-sided tape. There are great defects in the processing and production of this existing plastic card: 1. The production and processing technology is backward, and can only be processed ...
