A self-adhesive coating machine is a device specifically used for manufacturing self-adhesive labels. A self-adhesive label is a common type of adhesive label, which is coated with an adhesive layer on the back and can be directly attached to various object surfaces by removing the protective paper on the back.
The main function of the adhesive coating machine is to evenly apply the adhesive layer on the back of the adhesive label. This device typically consists of the following main components:
Coating system: The coating system usually consists of a coating roller or coating head. The coating roller is a rotating roller that extracts glue from the coating tank and evenly spreads it on the back of the label. The coating head is usually a uniform spraying device that sprays the adhesive evenly onto the label.
Control system: The control system is used to adjust the operating speed and pressure of the coating drum or coating head to control the thickness and uniformity of the coating adhesive layer.
Glue supply system: The glue supply system is used to supply the glue to the coating roller or coating head to ensure continuous supply and quality control of the glue.
Drying system: The coated adhesive label needs to undergo a drying process to quickly solidify the adhesive and form a sticky adhesive layer. The drying method can be natural drying or hot air drying.
The self-adhesive coating machine can also be equipped with other functions and devices, such as the stripping device for back protective paper, printing device, cooling device, etc., to meet different production needs and label design requirements.
The adhesive coating machine is widely used in industries such as packaging, logistics, and product labeling. Through the operation of this device, various self-adhesive labels can be efficiently produced, including barcode labels, product labels, logo labels, etc. It provides a fast, reliable, and high-precision method for manufacturing self-adhesive labels, meeting the needs of commercial and industrial fields for labels.
