Abstract

The invention discloses a stretching structure with good stability for producing uniaxially-stretched polyimide film, relates to the technical field of polyimide film production, and aims at solving the problems that an existing stretching structure is poor in stretching uniformity and low in overall flexibility. A metal roller, transition rollers and a limiting roller are installed in a stretching box, the limiting roller is located at the lower end of the metal roller, the transition rollers are located on the two sides of the metal roller, a motor is installed at one end of the metal roller, the metal roller is connected with the motor through a coupler, and the metal roller is connected with a stretching box through a bearing. Polyimide films are arranged outside the metal roller and the transition rollers correspondingly, a tensioning roller is installed on one side of the exterior of the stretching box, a rubber layer is arranged outside the limiting roller, the limiting roller is connected with the rubber layer in a glued manner, and an electromagnetic heating ring is arranged outside the stretching box. A heat insulation layer is arranged outside the electromagnetic heatingring.

Description

technical field [0001] The invention relates to the technical field of polyimide film production, in particular to a stretch structure for production of uniaxially stretched polyimide film with good stability. Background technique [0002] Polyimide film includes two types of polyimide film of phenylene type and polyimide film of biphenyl type. It is yellow and transparent, has outstanding high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties, and can be used for a long time in the air of 250 degrees Celsius to 280 degrees Celsius. Polyimide film is a polyimide film One of the earliest products, it is used for motor slot insulation and cable wrapping materials. Transparent polyimide film can be used as a flexible solar cell bottom plate. The main function of the stretch structure is to stretch the film horizontally according to a certain stretching ratio Stretch and imidize the polyimide film to a certain speci...
