Fixing device for laser film tension test

Abstract

The invention discloses a fixing device for a laser film tension test in the technical field of laser films. The fixing device includes a supporting plate, the left side of the bottom of the supporting plate is fixedly connected with fixing blocks in front-rear symmetry, a film rolling roller is rotatably connected between the two groups of fixing blocks, the front end of the film rolling roller is fixedly connected with a hand rotating rocker in a sleeved mode, the bottoms of the two groups of fixing blocks are fixedly connected with extension blocks correspondingly, the right sides of the two groups of extension blocks are fixedly connected with abutting blocks, the right side of the bottom of the supporting plate is fixedly connected with a vertical plate, the right parts of the abutting blocks are provided with compression blocks, and electric push rods are evenly and fixedly installed between the compression blocks and the vertical plate. The fixing device is suitable for the laser film tension test, a laser film is fixed and clamped, by inserting one end of the laser film into a clamping groove, elastic force produced by an elastic part enables a support pressing plate to clamp the laser film tightly, thus pre-fixation of the laser film is realized, and by manually rotating the hand rotating rocker, the film rolling roller can be driven to rotate, so as to be able to tighten the laser film.

Description

technical field [0001] The invention relates to the technical field of laser films, in particular to a fixing device for tensile testing of laser films. Background technique [0002] Laser film generally adopts computer dot matrix lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. From the composition of product components, laser film products can be roughly divided into OPP laser film, PET laser film and PVC laser film. kind. [0003] There are three main features of laser film: [0004] 1. Inherent aroma, strong anti-counterfeiting performance, beautiful, green, and environmentally friendly; 2. High ability to resist ink erosion, water vapor, and carbon dioxide; 3. Laser film has high gloss for cigarettes, and the holographic layer endows the film with better antistatic properties. Anti-adhesion and high machine adaptability. [0005] After the laser film is produced and formed, its tensile force needs to be teste...

Problems solved by technology

[0007] The object of the present invention is to provide a fixing device for laser film tensile testing, to solve the problem that the laser film fixing device of the existing laser film tensile testing machine proposed in the background technology only clamps and fixes it, and cannot adjust the excess length. The laser film is fixed after winding, which increases the difficulty of cutting the laser film for testing, which will greatly reduce the work efficiency of the staff.
