Method for detecting falling of paper lint and paper powder in paper straw

Abstract

The embodiment of the invention provides a method for detecting the falling of paper lint and paper powder in a paper straw, which comprises the following steps: providing a paper straw which comprises a side wall and a hollow part, the side wall comprises an inner side surface and an outer side surface, cutting the side wall along the length direction of the paper straw and flattening the side wall into a thin sheet which comprises a first surface and a second surface, a first transparent adhesive tape and a second transparent adhesive tape are attached to the first surface and the second surface respectively, a first image of the first surface and a second image of the second surface are obtained through a camera, the index V of paper lint and paper powder falling of the paper straw is obtained, and the paper lint and paper powder falling degree of the outer side face and the inner side face of the paper straw can be effectively detected. According to the method, the paper lint and paper powder falling performance of the paper straw is comprehensively evaluated, the operation is convenient, the precision is high, the paper lint and paper powder falling performance of the paper straw can be monitored in time, quality guarantee is provided for the paper straw, and the health and safety performance of the paper straw is improved.

Description

technical field [0001] The invention relates to the technical field of straws, in particular to a detection method of paper straws dropping paper wool. Background technique [0002] In recent years, the food service and packaging industries have developed rapidly. With the increasing awareness of environmental protection, paper straws have gradually replaced plastic straws due to their recyclability. At the same time, the safety performance of paper straws and their impact on human health It has also become the focus of consumers' attention. [0003] Paper straws are in direct contact with food and mouth when in use. The phenomenon of paper straws falling off paper wool will directly affect the safety performance of paper straws, which is not conducive to human health. Therefore, in production practice, it is urgent to develop a method that can reliably detect the drop of paper straws. The method of paper wool paper powder performance to ensure the safety of paper straws af...
