Description

Technical Field

[0001] The utility model belongs to the technical field of polarizer base film dust removal rollers and relates to a dust removal roller with high viscosity. Background Art

[0002] The polarizer base film transfer rubber roller is a key component in the polarizer production process. Polarizer is an important optical component, widely used in display technologies such as liquid crystal display (LCD) and organic light-emitting diode (OLED). The base film is an important component of the polarizer, and the rubber roller plays an important role in the production and transfer process of the base film. The surface cleanliness of the polarizer base film is crucial during the production process. In order to ensure the quality of the base film, a dust removal roller is usually used to remove dust from its surface. However, if the dust on the outer surface of the dust removal roller cannot be effectively scraped off, a series of problems will arise.

[0003] As dust accumulates, the surface of the dust removal roller becomes rough, which not only fails to effectively absorb dust on the surface of the base film, but may also cause scratches or damage to the surface of the base film, which will lead to a decline in the quality of the base film and affect subsequent production processes and product performance.

[0004] If the dust on the outside of the dust removal roller cannot be effectively scraped off, the dust is likely to be blown away by the wind and pollute the entire production workshop. Working in such an environment for a long time may not only affect the health of employees, but also affect the service life and maintenance cost of equipment. Therefore, a dust removal roller with high viscosity is urgently needed to solve the above problems. Utility Model Content
