Abstract

The invention relates to the technical field of polyester reflecting film preparation, in particular to a preparation method and device of a double-drawing polyester reflecting film. Comprising a carrier roller, a slitting table, a cutting assembly, a winding roller and a winding module, the winding module comprises a supporting column, a driving assembly, a rotating shaft, an adjusting assembly, a base, a rotating column, a rotating plate, a first adjusting spring, an attaching ring, an abutting plate, an abutting spring, an abutting block and a shifting rod, the driving assembly is fixedly connected with the supporting column, and the winding roller is detachably connected with the rotating shaft; one end of the rotating column is rotationally connected with the base, the rotating plate is rotationally connected with the rotating column, the abutting plate is fixedly connected with the attaching ring, one end of the abutting spring is fixedly connected with the abutting plate, the abutting block is fixedly connected with the other end of the abutting spring, and one end of the poke rod is fixedly connected with the abutting block. By means of the structure, the double-drawing polyester reflecting film winding device is suitable for winding double-drawing polyester reflecting films of different specifications, and the winding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of polyester reflective film preparation, in particular to a preparation method and device for a double-drawn polyester reflective film. Background technique [0002] Polyester reflective film has excellent mechanical properties, electrical properties and optical properties, so it has a wide range of applications. LED backlight refers to the use of LEDs as the backlight for LCD displays. In the Mini LED backlight, it is made of double-drawn polyester reflective film, thereby improving the production quality of the LED backlight. [0003] At present, when preparing double-stretched polyester reflective film, it is necessary to rewind the stretched polyester reflective film, but the specifications of polyester reflective film are different, and it is not convenient to rewind double-stretched double-stretched films of different specifications during the winding process. Polyester reflective film, poor winding...
