纵拉机

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.
