Uncoiling device for relief three-dimensional holographic image thermal shrinkage film production

Abstract

The invention discloses an uncoiling device for relief three-dimensional holographic image thermal shrinkage film production. The uncoiling device comprises a bottom plate; supporting columns are mounted at the four corners of the bottom of the bottom plate, rolling wheels are mounted at the bottoms of the supporting columns, and locking mechanisms are mounted between the inner sides of the supporting columns; and an electric push rod is mounted in the center of the top of the bottom plate, a base is mounted at the top of the electric push rod, a frame body is mounted at the top of the base, adriving mechanism is mounted on the left side wall of the frame body, and a control panel is mounted on the right side wall of the frame body. The driving mechanism drives a second bidirectional leadscrew to rotate, the second bidirectional lead screw drives sleeves to slide towards the two sides while rotating, and thus a movable rod rotates; and the movable rod rotates to push uncoiling supporting plates to slide in inner cavities of sliding grooves through sliding blocks, thus the distance between the uncoiling supporting plates is convenient to adjust, thus the device can uncoil thermalshrinkage films with different widths, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of heat shrinkable film unwinding equipment, in particular to an unwinding device for producing heat shrinkable film with embossed three-dimensional holographic images. Background technique [0002] In recent years, my country's printing and packaging industry has developed rapidly. The market's demand for adapting to people's ever-changing spiritual culture and green environmental protection has become more intense and urgent. Concavo-convex image, three-dimensional holographic image is a kind of image that is very different from traditional photos, so it needs to be transmitted by unwinding equipment when used, but there are still some shortcomings in existing unwinding equipment: [0003] Most of the traditional devices are fixed, and the device cannot be adjusted according to the width of the heat shrinkable film, which reduces the practicability of the device. In addition, when the traditional device is ...
