Description

Technical Field

[0001] This utility model belongs to the technical field of thin film slicing equipment, and in particular relates to a roll-cutting thin film slicing equipment. Background Technology

[0002] A polarizer is an optical film with selective light transmission capability. Its core function is to convert unpolarized light into linearly polarized light vibrating in a specific direction, or to filter polarized light. It allows light from only one direction to pass through. In liquid crystal display panels, two polarizers are usually placed, one on the upper surface and one on the lower surface of the liquid crystal layer. The lower polarizer converts the unpolarized light emitted from the backlight into linearly polarized light. The liquid crystal layer controls the twisting angle of the liquid crystal molecules according to the pixel voltage, thereby rotating the direction of the incident polarized light. The upper polarizer acts as an analyzer, allowing only light with the same polarization direction as its polarizer to pass through, thus controlling the light and forming an image.

[0003] In the production process of existing polarizing films, thin film slicing equipment is typically used to slice the entire sheet of film. The existing thin film slicing method combines a die-cutting mechanism and a traction pressure bar. In the specific implementation process, the traction pressure bar sequentially conveys the entire sheet of film toward the die-cutting mechanism one step, and the die-cutting mechanism slices the conveyed sheet of film into sheets. To avoid the phenomenon of double-cutting between two adjacent sheets, a gap of film is left between the previous sheet and the next sheet. Therefore, the above method of slicing film results in low film utilization due to the presence of gap film. Utility Model Content

[0004] The purpose of this invention is to provide a roll-cutting film slicing device to solve the problem of low film material utilization in conventional film cutting methods in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution: A roll-cutting film slicing device includes a conveying assembly, a slicing mechanism, and a receiving assembly, wherein: The slicing mechanism is disposed on the conveying path of the conveying assembly.
