Wrapping paper indentation detecting device

Abstract

The invention relates to a wrapping paper indentation detecting device. The device is arranged on a bracket. A template is arranged at the bottom of the bracket and is provided with a sample model hole. A sample clamping plate is arranged above the template and is fixed by a nut. A paper sample to be detected is fixed between a clamping plate and the template. The indentation of the paper sample exactly faces the model hole. The clamping plate is provided with a through hole, and the through hole exactly faces the model hole. A positioning hole is arranged above the bracket. A pressure rod is inserted in the positioning hole. The lower end of the pressure rod exactly faces the through hole on the fixing plate. The upper end of the pressure rod is provided with a support plate. A weight is arranged on the support plate. By adopting the technical scheme, the paper sample to be detected is fixed between the clamping plate and the template, the pressure rod is pressed on the cutting mark of the paper sample, and then the instant and direct pressure detection can be carried out on the cutting mark by putting the weight on the support plate.

Description

technical field [0001] The invention belongs to the technical field of printing and packaging, and relates to a detection device for detecting the indentation quality of packaging paper. Background technique [0002] In the production of printing and packaging, many papers for packaging boxes need to be pressed with half-cut holes. The half-cut holes generally correspond to the tearing position of the packaging box. If the indentation of the cutting holes is too shallow, the packaging box will be difficult to tear when opened. If the indentation of the cut hole is too deep, the compressive performance of the packaging box is poor, and it is easy to break from the cut. In actual production, the quality of the cutting holes must be checked frequently, and the cutting pressure of the cutting equipment should be adjusted in real time, so as to avoid the scrapping of batches of products. However, in the current actual work, due to the lack of special detection equipment for hole...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the lack of quality inspection devices for half-punctured holes in packaging boxes in the prior art, and the detection process is cumbersome, time-consuming and labor-intensive. It provides a convenient and quick packaging paper indentation detection device for instant half-punching Cut holes for quality inspection, and adjust the cutting depth of automatic production equipment in real time according to the inspection data to avoid or reduce the generation of unqualified products
