A fixing device for laser film tensile test

Abstract

The invention discloses a fixing device for the tensile test of the laser film in the technical field of the laser film, which includes a support plate, and fixed blocks are fixed symmetrically front and back on the left side of the bottom of the support plate, and two groups of the fixed blocks are rotationally connected with each other. The film rolling roller, the front end of the film rolling roller is sleeved and fixed with a hand-rotating rocker, the bottom of the two sets of fixed blocks is fixed with an extension block, and the right side of the two sets of extension blocks is fixed with an abutment block , the right side of the bottom of the support plate is fixedly connected with a vertical plate, and the right side of the abutment block is provided with a pressing block, and an electric push rod is evenly fixed and installed between the pressing block and the vertical plate. In the laser film tensile test, it is fixed and clamped. By inserting one end of the laser film into the clamping groove, the elastic force generated by the elastic member will clamp the supporting platen to the laser film, so as to realize the pre-fixation of the laser film. Turning the rocker by hand can drive the film rolling roller to rotate, so that the laser film can be tightened.

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.
