Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a constant temperature platform for a scraper coating machine. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. Specific applications include packaging, advertising car stickers, wedding displays, hospital CT films, food labels, inner coatings for paper cups, conductive layers, insulating films, chip lamination, coatings for reflective materials, reflective films for safety signs, car covers, and skin-feel films for robots. The coating platform of the coating machine needs to be heated to a certain temperature to prevent the coating from hardening too quickly. However, existing coating machines usually heat the coating platform by adding heating wires at the bottom. The heating and cooling rates of the heating wires are too fast, which can easily cause the coating platform to overheat, affecting the normal use of the coating. Utility Model Content
