Description

Paper tube cutting machine

This invention relates to a cutting machine, in particular to a paper tube cutting machine that utilizes rotation for rolling cutting.

The production of paper tubes mainly involves winding at least one paper strip into a round tube shape, and bonding the overlapping parts of the winding together to form a paper tube, and then conveying the paper tube forward and cutting it through a cutter to achieve a paper tube of a preset length. The paper tube can be widely used, such as making paper straws and other products.

The paper straw is designed with a beveled insertion portion at one end to facilitate puncturing the sealing film, and a flat-cut sucking port at the other end to facilitate drinking. During the production process, the paper tube is first made into a tubular semi-finished product with beveled insertion portions at both ends, and then the tubular semi-finished product is cut in the middle using a paper tube cutting machine to make two finished paper straws. It is known that when the paper tube cutting machine performs the cutting operation, the paper tube semi-finished product is fixed in position, and then the middle of the tubular semi-finished product is cut using a cutting knife. However, since the material of the tubular semi-finished product is soft, the flat-cut sucking portion is easily flattened after being cut, affecting product quality.

The author of this invention, in view of the above-mentioned shortcomings of the known paper tube cutting machine, came up with the idea of creating this invention. After much discussion and trial production of samples, as well as many revisions and improvements, this invention was launched.
