In order to supply a large amount of demand, most of today's common straws are plastic tube strips, which can be directly cut into the required length and completed, in order to achieve rapid production. But not all drinks are so simple about the matching straws.

For example, sometimes the straw needs to be packaged with the drink. In this case, the length of a single straw will protrude from the drink, which makes it too long and the straw is often damaged by foreign objects. Therefore, it is necessary to produce another telescopic straw to replace it. Single length straws.

However, the current machines for manufacturing telescopic straws are too simple and cannot satisfy all production procedures at one time. Therefore, it is necessary to provide a novel and progressive straw machine to solve the above problems.
