Coating switching device for adhesive sticker

Abstract

The invention discloses a coating switching device for an adhesive sticker. The coating switching device comprises a glue tank and a roller set, wherein an introduction roller is movably arranged at the top of one side of the glue tank; the roller set is arranged at the inner side of the glue tank; a drawing-off roller is movably arranged at the top of the other side of the interior of the glue tank; a glue scraping mechanism is arranged in the glue tank; a stirring mechanism is arranged at the bottom in the glue tank; the roller set comprises a glue rolling roller, a pressing roller, a turning roller and a switching roller; the glue rolling roller, the pressing roller, the turning roller and the switching roller are sequentially arranged at the inner side of the glue tank; a rotating shaft of the switching roller is movably connected to a connecting rod; and the glue scraping mechanism comprises a first supporting rod, a bolt, a first scraping plate, a second supporting rod and a second scraping plate. The coating switching device for the adhesive sticker has the function of stirring the glue solution, precipitation of the glue solution is avoided, meanwhile, the glue solution is prevented from being dried and fixed on the second scraping plate, and the coating switching device is beneficial to use.

Description

technical field [0001] The invention relates to the field of switching coating devices, in particular to a self-adhesive switching coating device. Background technique [0002] The self-adhesive switching coating device is a device used to switch the coating during the production of self-adhesive. Self-adhesive is also called self-adhesive label material. It is made of paper, film or special material, and the back is coated with adhesive. A composite material with silicon-coated protective paper as the base paper. Because the thickness of the adhesive required for each place where the self-adhesive is used is different, it is necessary to use a coating switching device to change the thickness of the adhesive; the existing self-adhesive When applying glue, there is no stirring function, which will easily lead to the phenomenon of precipitation of the self-adhesive, which is not conducive to switching the thickness. At the same time, there is no heating device. The glue on the...
