Description

Incision pressing tool for paper suction tube Technical Field The utility model relates to the field of straw processing equipment, in particular to a notch pressing tool for a paper straw. Background The paper straw has the remarkable technical problems in practical application that the spike end of the paper straw, namely the part for puncturing the sealing film of the beverage package, is easy to bend and crack and even leads to the integral failure of the straw when being used for multiple times or stressed due to the weak structure, directly influences the user experience and limits the popularization of the paper straw in high-frequency use scenes, such as take-out of food and drink pre-package; although the prior art has a method for improving local strength by increasing the number of layers or gram weight of paper, the method can lead to reduced flexibility and increased cost of the straw, and is not in line with the environmental protection concept.
