Abstract

The invention discloses an active film unwinding device, which comprises a bracket, an unwinding mechanism arranged on the bracket and a guide roller; the unwinding mechanism includes a fixed frame, an unwinding assembly arranged on the fixed frame, a transitional roller and an unwinding tensioning tube; the fixed frame is provided with a transitional roller mounting frame for assembling the transitional roller; the transitional roller mounting frame is also provided with a speed test feedback mechanism; the unwinding assembly includes a bearing seat arranged on the fixed frame, a bearing in a bearing seat, an air expansion shaft with two ends supported by the bearing, and a servo motor for driving the air expansion shaft to rotate as well as a synchronous belt wheel; and the speed test feedback mechanism is connected with the servo motor. The active film unwinding device disclosed by the invention is suitable for unwinding of film easy to stretch and deform; and when the film is unwound, the film unwinding speed is ensured to be the same as the transmission speed of a tricot machine by the speed test feedback mechanism, thereby avoiding film stretching and deformation.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an active film unwinding device for unwinding film on a warp knitting machine. Background technique [0002] In the field of warp knitting, it is often necessary to unwind the film on the warp knitting machine, especially when producing thermoplastic composite materials, it is necessary to use the unwinding of the resin film, because the resin film is soft, and the unwinding speed needs to be adjusted during unwinding. control to make it consistent with the transmission speed of the warp knitting machine, otherwise the resin film will be stretched and affect its use effect. The speed is controlled, therefore, the stretching of the film cannot be solved. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing unwinding device described in the background technology cannot control the unwinding speed, which leads to stretching of ...
