Description

Technical Field

[0001] The utility model relates to the technical field of label waterproof coating, in particular to a waterproof label coating machine. Background Art

[0002] A label is an identifier used to identify, classify and describe things. In order to improve the waterproof performance, durability and quality of the label, a coating machine is required to coat a layer of waterproof coating on the surface of the label. The waterproof coating can form a dense protective film, which effectively prevents moisture from penetrating into the interior of the label, so that it can maintain good performance and appearance in various environments and usage conditions.

[0003] Before the existing coating machine applies the waterproof coating to the label surface, there may be dust, oil or other impurities on the label surface. If it is not cleaned, the waterproof coating will not be evenly adhered during the coating process. These impurities may form a barrier layer, making it impossible for the waterproof coating to completely cover every part of the label, resulting in uneven coating thickness, affecting the waterproof effect. In addition, after the existing coating machine completes the coating on the label, it does not have a drying structure to quickly dry the coating, and a certain curing process is required to form a strong and durable waterproof layer.

[0004] For example, the announcement number CN207833778U discloses an on-demand self-adhesive label production device. In this patent, there is no cleaning mechanism to clean the surface of the label before coating, and after the label is coated by the glue roller, the coated label needs to wait for a long time to wait for natural air drying. The air drying method is often affected by factors such as environmental humidity and temperature, resulting in uneven drying of the coating, which may cause local moisture or spots on the label surface, affecting the appearance and waterproof effect, while greatly extending the production cycle and reducing production efficiency.

[0005] Therefore, it is necessary to invent a waterproof label coating coating machine to solve the above problems. Utility Model Content
