Multi-angle circular stretching device for film

Abstract

The invention relates to a multi-angle circular stretching device for a film. According to the stretching device, stretching of multi-angle joints on a two-dimensional plane can be met, and the uniformity of film stretching can be greatly improved, so that the flattening degree of plane stretching is greatly improved. According to the technical scheme, the stretching device comprises a lead screw,the lower end of the lead screw is connected with a stepping motor base, an up-down moving device penetrates through the middle of the lead screw, a polygonal disc is arranged at the top of the leadscrew for assembling and fixing, and the lead screw is connected with a stepping motor through a coupler; and the support corners of the polygonal disc is connected with guide shafts, the other ends of the guide shafts are connected with guide shaft supporting bases, the guide shafts are sleeved with linear bearings capable of sliding back and forth, the linear bearings are fixedly connected withbearing connecting bases, the upper portions of bearing connecting bases are connected with clamping bodies, the lower portions of the bearing connecting bases are fixedly connected with conduction rods, the other ends of the conduction rods are movably connected to the up-down moving device, and the number of the guide shafts on the circumference of the up-down moving device is the same as that of the conduction rods.

Description

technical field [0001] The invention relates to the technical field of multi-angle circular film stretching on a two-dimensional plane, in particular to a multi-angle circular film stretching device. Background technique [0002] The planar stretching device occupies an important position in the current scientific research, such as the piezoelectric film field, photoelectric conversion and other flexible film fields, etc., because in the film stretching process, the uniformity and flatness of the stretching have a huge impact on its performance. Impact. Therefore, how to stretch the film well has become a necessary condition for scientific performance research. [0003] At present, the most widely used stretching methods are single-end stretching and plane stretching only for XY two directions. [0004] Insufficient stretch flatness in the process of single-end stretching, and large-area wrinkles in the center and both sides of the film are unavoidable problems in the curr...

Problems solved by technology

[0004] Insufficient stretch flatness in the process of single-end stretching, and large-area wrinkles in the center and both sides of the film are unavoidable problems in the current device;

[0005] Although the plane stretching equipment in the XY direction has completed the two-dimensional plane stretching work, it only stretches in the horizontal and vertical directions of the plane, showing a square stretching state, so the stretching effect is not as perfect as imagined, especially There is no accurate representation of the film stretching and expansion process in reality, so today's stretching devices can no longer meet the high-precision requirements of film stretching
