Embodiment Construction

[0011] The basic principle of the repeatable self-adhesive spreading method of the present invention is exactly to cut off the above-mentioned spread coating equipment of tens of meters to tens of meters into small sections of spread coating devices of half a meter to one meter, and then, layer by layer, the soft Replace the paper or cloth base with a non-stick board, put it on a multi-layer rack, introduce cold and hot air to dry, spread it for a second time after drying, and reciprocate, and then transfer to other linings such as interlining cloth or interlining paper It realizes repeatable self-adhesive spreading to make thick-coated products.

[0012] Repeatable self-adhesive spread coating method of the present invention is realized like this:

[0013] (1) Spreading First, spread the adjusted self-adhesive colloid evenly on the anti-adhesive board through a flat-plate spreading device to form an adhesive layer, and then place it on a multi-layer support;

[0014] (2) Dry...

Abstract

The invention is a repeatable adhesive smearing method, including the stages: smearing: uniformly smearing the adhesive on anti-adhesive plate by plate smearing device, placing the plate on a multilayer bracket; drying: leading cold wind and hot wind to the multilayer, where the cold wind is natural wind and the hot wind is 30-40 degrees; smearing again: repeating the first smearing procedure, able to smear adhesive and also medicine and medicament to form a medicine house layer, this stage can be repeated many times to make the smeared thickness up to 1-2mm; transferring: pasting a substrate on the last smeared adhesive layer, the substrate can adopt cloth, paper, nonwoven cloth or other fabrics. Then, reversing the anti-adhesive plate and peel it off and pasting on transparent film.

Description

technical field [0001] The invention relates to a glue coating process, in particular to a repeatable self-adhesive spreading method. Background technique [0002] Generally, the existing self-adhesive spreading equipment uses a conveyor belt (conveyor chain) as a conveying device to spread the colloid on paper or cloth or on a rolled substrate. The equipment is relatively long, from about 10 meters to 60 meters. There are different lengths of about one meter, mainly for the production of self-adhesive tapes. In production, the glue coating is very thin, so the production efficiency is very high. The longer the equipment used, the higher the efficiency and the more stable the quality of the product. [0003] With the development of the economy, self-adhesive products are widely used, but new requirements are also put forward for self-adhesive products, such as small batches, thick coatings, products that are repeatedly coated, and the needs of adapting to different human sk...
