A self-adhesive product coating machine

Abstract

The invention discloses a coating machine for an adhesive product. The coating machine comprises a rack, a drying device, a compounding device, a coating device and a winding device, wherein the coating device comprises a discharging mechanism, a top block and a scraping mechanism; the scraping mechanism comprises a material collecting box, a baffle and a material melting component; a material collecting port is formed in the right side of the material collecting box; the material collecting port is obliquely provided with a scraper; in addition, a plurality of feeding troughs are formed in the bottom of the material collecting box; the top block is provided with a paper absorbing mechanism. According to the coating machine disclosed by the invention, excess materials can enter the inner part of the material collecting box through the material collecting port and further are convenient to recover, so that the phenomenon that glue is exposed in air for a long time to draw wires is avoided; without removing the glue on the scraper, the working efficiency is greatly improved; the plurality of feeding troughs are formed in the bottom of the material collecting box, so that the excess materials can flow out of the feeding troughs for filling glue holes and further the coating effect is ensured; by arranging the paper sucking mechanism, up-down floatation of backing paper in the coating process can be avoided, the uniformity of coating is ensured and further the coating effect is improved.

Description

technical field [0001] The invention belongs to the field of self-adhesive products, and in particular relates to a self-adhesive product coating machine. Background technique [0002] A coating machine is a mechanism suitable for applying adhesives, coatings, etc. to rolls of substrates. Self-adhesive products usually include face paper, glue, and base paper, wherein the glue needs to be hot-melted and coated on one surface of the base paper, and the face paper and the surface coated with glue on the base paper are attached to each other. [0003] When the existing equipment is coated with self-adhesive, if the glue stays on the backing paper for a long time, there will be glue drawing. The scrap rate is high. If the drawing sticks to the pressure roller and cannot be dealt with in time, the drawing will become thicker and thicker, which will also affect the coating effect. In order to solve this problem, the commonly used method is to use a scraper to press The roller is...

Problems solved by technology

[0003] When the existing equipment is coated with self-adhesive, if the glue stays on the backing paper for a long time, there will be glue drawing. If these drawing appear on the backing paper, it will have a major impact on the quality of self-adhesive products, causing The scrap rate is high. If the drawing sticks to the pressure roller and cannot be treated in time, the drawing will become thicker and thicker, which will also affect the coating effect. In order to solve this problem, the commonly used method is to use a scraper to press The roller is used to remove the glue, and the scraper is expensive, and needs to be replaced after several uses. First, it affects work efficiency, and second, it increases the production cost of the enterprise.
