Technical Field

[0001] This utility model relates to the field of TPU film processing technology, and in particular to a TPU film darkroom inspection frame. Background Technology

[0002] TPU film is a thermoplastic polyurethane and also an environmentally friendly polymer. It is non-toxic and wear-resistant. TPU film is made from TPU granules through special processes such as calendering, casting, blown film production, and coating. Due to its good elasticity, excellent physical properties, and high mechanical strength, it can be widely used in various places requiring decoration and in various industries.

[0003] However, TPU film production requires random sampling inspection. The common inspection method is manual observation to check for impurities and the molding condition of the TPU film. For different types of TPU film, darkroom observation with light is a common method. However, the general darkroom observation method simply suspends the film and illuminates it manually. But this can only observe a part of the TPU film and cannot observe it at different lighting angles when the film is tilted. Therefore, a TPU film darkroom inspection frame structure is needed to achieve better observation of TPU film. Utility Model Content
