Paper straw manufacturing system capable of forming wrinkles while cutting {PAPER STRAW MANUFACTURING SYSTEM THAT CAN BE CUT AND WRINKLED AT THE SAME TIME}

The present invention relates to a paper straw manufacturing system, and more particularly, reduces the manufacturing time of paper straws provided with wrinkles by cutting and forming wrinkles at the same time as cutting preliminary straws heated by hot air and wound around a core rod. In the present invention, when a heat wire is installed inside the core bar to form wrinkles, heat is transferred to the preliminary straw to make it flexible, and then wrinkles are formed, so that the wrinkles remain stable even after cooling. Paper capable of forming wrinkles at the same time as cutting It is about a straw manufacturing system.

In general, disposable beverage containers provided by convenience stores, marts, cafes, etc. are provided with straws having a predetermined length so that users can easily consume packaged beverages.

Conventional straws are often formed of plastic materials. Straws made of plastic have advantages in that they are easy to process, have low manufacturing costs, are light in weight, and do not cause problems in mixing other ingredients in beverages when used. However, due to the nature of the material, it takes a very long time to decompose after being discarded, and since it is harmful to the human body, voices are growing that it should be replaced.

As a solution to these needs, developments are continuously being made on a method of reusing the manufactured straw or a method of replacing the straw component itself with an environmentally friendly material. For example, straws made of reusable plastic or metal are proposed. However, straws are often used for businesses, and in this case, reuse and use of straws has limitations in terms of hygiene or infrastructure of each establishment.

For this reason, disposable straws made of paper have recently been proposed. Disposable straws made of paper material are not only harmless to the human body, but also have sufficient value to replace conventional plastic straws in that they minimize environmental pollution.

These paper straw manufacturing systems are published in Korean Patent Registration Nos. 10-1973367 and 10-2197630.
