The invention discloses a film sample heat shrink performance detection device. The device comprises a base, a film fixing rack mounted on the base, a liftable heating cavity arranged right above the film fixing rack, an encoder connected with a controller, a roller and a tension sensor, wherein one shrink rate detection station and one shrink force detection station are at least arranged on the film fixing rack; the heating cavity is used for heating film samples on the film fixing rack; the roller is mounted on a spindle of the encoder and fixedly connected with the film sample at the shrink rate detection station, when the film samples shrink with heat, the encoder is used for detecting rotation angle information of the roller when the film samples shrink with heat and sending the rotation angle information to the controller, and the controller calculates the shrink rate of the film samples according to the diameter of the roller; the tension sensor is mounted on the base, directly connected with the film sample at the shrink force detection station and used for detecting the tension of the film samples in the heat shrink process and sending the tension to the controller so as to obtain the heat shrink force of the film samples.
Description
technical field [0001] The invention belongs to the technical field of testing, and in particular relates to a detection device for thermal shrinkage performance of film samples. Background technique [0002] Films are widely used in the packaging industry, but most films have a certain degree of heat shrinkage, which will affect the packaging performance of the film, so it is necessary to test the heat shrinkage of the film. The heat shrinkability of the film includes heat shrinkage rate and heat shrinkage force. For different products, the heat shrinkage rate and heat shrinkage force of the film must be appropriate and stable, among which the appropriate heat shrinkage rate and heat shrinkage force can make the packaged product look full, tight and fit; stable heat shrinkage rate and heat shrinkage force The thermal shrinkage force can maintain the uniformity of the size of the packaged product. Therefore, it is of great significance to quantitatively detect the heat shr...
