A film planar stretching device with flexible pneumatic stretching

Abstract

The invention relates to a film plane stretching device with flexible pneumatic stretching. The device can meet the plane stretching requirements of different stretching ratios, and can also reduce adverse effects in the stretching process and improve the flatness of the plane stretching. The technical solution of the present invention includes a square base; a guide rail is respectively provided from the four corners of the base to the center direction, each guide rail is provided with a sliding seat that can slide along the guide rail, and each sliding seat side is arranged with 2 pairs of Misplaced through holes, X-axis slide rails are arranged in the two through holes at the upper ends of the left and right slide seats, and Y-axis slide rails are provided in the two through holes at the lower ends of the upper and lower slide seats to form a guide device; each slide seat has another One side is provided with simply supported rods, and two adjacent simply supported rods are provided with telescopic air pipes, and the telescopic air pipes are connected to the X-axis slide rail or the Y-axis slide rail through several clamping devices with equal spacing; An air inlet and an air outlet are respectively arranged to form a pneumatic telescopic device.

Description

technical field [0001] The invention relates to a film plane stretching device with flexible pneumatic stretching. Background technique [0002] Planar stretching devices occupy an important position in current scientific research, such as the field of piezoelectric films, photoelectric conversion films, etc. During the film stretching process, the uniformity and flatness of the stretching have a huge impact on the film properties. . Therefore, how to stretch the film well has become a prerequisite for scientific performance research. [0003] At present, the most commonly used stretching methods are purely mechanical, including single-end stretching and simple plane stretching. 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 of current devices; although simple plane stretching equipment solves the problem of stretch flatness, The stretched wrinkles are also su...

AI Technical Summary

Problems solved by technology

Insufficient stretching flatness in the process of single-end stretching, and large-area wrinkles in the center and both sides of the film are inevitable problems in current devices; although simple planar stretching equipment solves the problem of stretching flatness, The stretched wrinkles are also suppressed, but the solution effect is not as perfect as imagined, especially for the processing of the boundary elongation problem along the boundary direction during the stretching process, and for film-type flexible materials, the stretching The variation of the film ratio is relatively wide, and the current stretching device can no longer meet the requirements of film stretching.
