Problems solved by technology

There are many longitudinal stretching machines produced by domestic and foreign manufacturers, but the longitudinal stretching machines dedicated to the production of electronic grade BOPI film are almost blank
For the longitudinal stretching of BOPI film, due to the different process requirements, the performance of the traditional longitudinal stretching machine is unreliable, and the stretching ratio cannot be fine-tuned within the range of process requirements, so it can only be put into use after a series of modifications
Moreover, frequent maintenance is required during the operation of the longitudinal stretching machine
It will have an adverse effect on the normal operation of the entire production line

Abstract

The invention relates to a longitudinal drawing machine special for longitudinally drawing an electronic grade biaxially oriented polyimide (BOPI) film. The machine comprises a longitudinal drawing machine body (1), wherein the longitudinal drawing machine body (1) comprises a driving end wallboard (1.1), a driven end wallboard (1.3) and a bearing component (1.5); a roller system (3) is arranged between the driving end wallboard (1.1) and the driven end wallboard (1.3) of the longitudinal drawing machine body (1); various rollers in the roller system (3) are supported by the bearing component(1.5) which is arranged on the driving and driven end wallboards of the longitudinal drawing machine body; a set of manual system (4) is arranged on a shaft of each roller in the roller system, whichis positioned on the inner side of the driven end wallboard (1.3); a set of gear transmission system (2) is arranged on various roller shafts on one side of the roller system (3) outside the driving end wallboard (1.1) of the longitudinal drawing machine body (1); and the gear transmission system (2) comprises a driving gear (2.1), a driven gear (2.2), a power transmission gear I (2.3), a power transmission gear II (2.4), a drawing gear I (2.5) and a drawing gear II (2.6). The longitudinal drawing machine has reliable performance and is maintenance-free, and a drawing ratio can be finely adjusted in a range required by a process.

Description

technical field [0001] The invention relates to a longitudinal stretching machine for biaxially stretching polyimide film production, in particular to a longitudinal stretching machine specially used for longitudinal stretching of electronic-grade BOPI films. The utility model belongs to the technical field of longitudinal stretching machine specially used for producing polymer resin film. Background technique [0002] Biaxially oriented polyimide film (BOPI film) is a new material in recent years, it is a special polyimide film. Due to the biaxially stretched molecular structure, BOPI film has superior physical, chemical and electrical properties. Operating temperature -269°C to +260°C. It is no problem to work at a temperature of 420°C for a short time. Moreover, the BOPI film also has the performance of resisting atomic radiation. This makes it the compound with the highest heat resistance and the best comprehensive performance in the world. [0003] Longitudinal str...
