Description

Straw machine

The present invention is related to the straw machine.

In order to supply a large amount of demand, most of the common straws today are plastic tube strips, which are directly cut to the required length and then completed, in order to be able to produce quickly. But not all beverages have such simple requirements for the straws that match them.

For example, sometimes the straw needs to be packaged with the drink. At this time, the length of a single straw will protrude from the drink, and it will be too long and the straw will often be damaged by the concave or break of foreign objects. Therefore, it is necessary to produce another telescopic straw to replace it. A single length of straw.

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